Designing Training Programs to Introduce Emerging Technologies to Future Workers—A Pilot Study Based on the Example of Artiﬁcial Intelligence Enhanced Robotics

: Implementing an Emerging Technology (ET) is a difﬁcult task due to people lacking ET-related knowledge and skills or having skeptical and negative attitudes towards the ET. As learners construct their understanding about an ET and develop related skills by actually passing through the ET Innovation Process (IP) stages (Awareness, Acceptance and Adoption), it could be useful to provide them with training that imitates certain IP stages. Using Artiﬁcial Intelligence Enhanced Robotics (AIER) as the example ET, we designed a two-day workshop to lead learners ( n = 16) through the AIER IP Awareness stage, and a six-week training course with eight contact days to simulate the AIER IP Acceptance stage to learners ( n = 10). Using online surveys and quantitative content analysis methods we conﬁrmed that the workshop format increased the AIER-related self-conﬁdence and general knowledge in 78% of participants, while the training course helped more than half of the participants to construct usable knowledge about a speciﬁc AIER and to see its possibilities in their speciﬁc work-place contexts. This paper is the pilot of using the Technology-Enhanced Learning Innovation Process (TELIP) model, ﬁrst tested on a STEAM innovation, outside the educational context, for developing appropriate training approaches for speciﬁc ET IP stages.


Introduction
The emerging technologies of the 21st century are expected to have a great impact on society [1]. Emerging Technologies (ETs) can make people's lives easier and more meaningful, but they will potentially present also several challenges that need to be addressed. One of these challenges is to equip today's workforce with the necessary skills and knowledge that would make it easier for the workers to embrace ETs. The educational system plays an important role in developing basic skills and increasing the supply of specific skills, often acquired throughout the career. The best practices and the latest technologies used at the productivity frontier generally require a more highly skilled workforce [2]. More emphasis should be given to training and lifelong learning, where substantial scope exists for possibilities to improve training uptake and quality [3]. In this paper, we examine how to design and conduct a Training Course (TC) that aims at introducing ETs to adult persons in a way that would inspire them to choose ET-related careers.
A technology is considered emerging if it is novel in a given context and its full potential would most likely be realized in the future, not in the present day. If successfully sustained, an ET can have an incremental or disruptive influence on the domain where it is used-its use can create new additional opportunities or displace already existing routines, ness stage is "merely" a demonstration of the technology-related possibilities-while the Acceptance stage can be passed in an environment simulating a workplace. In case the users do not need to use the technology in their everyday routines in the present but might need it in the future, they need to be provided with a hands-on practical TC that simulates the stages of Awareness and Acceptance. The purpose of such a course could be proactively evoking positive attitudes and to avoid the possibility of the formation of negative attitudes towards an ET. The TELIP model was developed as a response to the problem of STEAM (Science, Technology, Education, Art and Math) focused Technology-Enhanced Learning (TEL) innovations' sustainability in teachers' practices. Namely, many STEAM TEL innovations, despite starting with great enthusiasm will fade without leading to significant changes in educational activities [27,28]. The TELIP model aimed at explaining the nature of the STEAM TEL innovation process and factors that influence its outcomes. In order to develop the TELIP model, the innovation process of a certain STEAM TEL innovation, robotsupported math teaching and learning [26] was examined during a four-year study that involved 137 math teachers, 56 educational technologists, and more than 2000 students from 67 Estonian schools. Although the TELIP model was first tested during a long-term study with educational robotics in the school context, it is based on a synthesis of several well-known technology acceptance and innovation adoption models: The Diffusion of Innovations Theory by [24], The Technology Acceptance Model by [25,29], The Technology-Organization-Environment Framework by [30], and The Unified Theory of Acceptance and Use of Technology by [31]. This origin makes it possible to apply the model, with certain reservations, to other technological innovations in other contexts. The three-stage nature of innovation adoption at the end-user level is also described by several earlier models, e.g., [32][33][34][35][36][37][38][39]. However, the TELIP model uniquely describes IP factors that influ- In a way, the Adoption stage can only take place in a real work context, the Awareness stage is "merely" a demonstration of the technology-related possibilities-while the Acceptance stage can be passed in an environment simulating a workplace. In case the users do not need to use the technology in their everyday routines in the present but might need it in the future, they need to be provided with a hands-on practical TC that simulates the stages of Awareness and Acceptance.

The three-stage nature of innovation adoption at the end-user level is also described by several earlier models, e.g., [32][33][34][35][36][37][38][39]. However, the TELIP model uniquely describes IP factors that influence the outcome of IP stages, impacting thus the ability of an innovation to become sustainable. These factors are the following: technological factors, organizational factors, personal factors, perceived value factors and social practices' factors. The combination of active factors in each IP stage also indicates the support that is needed by the end-users during the IP stage, facilitating the planning of the innovation process.
This paper presents a pilot use of the TELIP model outside the educational context. We are going to use the TELIP model as a guiding framework for developing a possible solution for the problem of people having insecurities, or even unconscious fears towards actively seeking ET-enhanced jobs. We theorize that by the means of specially developed training courses that consider relevant IP stages it is possible to encourage people to look forward to working with ETs and to support their self-confidence about becoming "future compatible" or being able to take advantage of the choices that include the element of ETs. One of the suggestions the TELIP model offers is that people who exit an IP stage with negative attitudes towards the ET, will have difficulties in re-entering that stage or the next one, ( [26], suggested also by [24]). As re-engaging these people requires more effort to convince them about the feasibility of the ET, it could be more useful to provide people with TCs that, depending on their previous knowledge and experience, imitate certain IP stages. Such a TC should allow people to exit the appropriate IP stage with positive attitudes that help them to successfully enter the next IP stage, leading to final adoption of the ET.
At this point, we propose that for leading people into and through the ET IP Awareness stage it is appropriate to use the workshop format-a short training course with a duration of two days. A workshop is often used as a learning method to evoke systematic changes in people's attitudes and behaviors. During a workshop, active learning is encouraged through a short-term learning experience [40]. Active learning is suitable for developing adaptability, creativity, curiosity and open-mindedness [41]-characteristics that help people to become interested in the subject learned. In a typical workshop, learners are actively engaged with their peers and their teachers. The format of a workshop as a onetime event could be suitable for creating awareness about a certain ET (i.e., to lead people to and through the Awareness stage). We also suggest that convincing people to choose for ET-related careers (i.e., to enter and pass the Acceptance stage) might require a longer-term TC. The purpose of such a TC would be to provide people with a combination of theoretical knowledge and practical experience, in order to form positive future expectations about the studied ET. The duration of this TC should be at least the same as the minimum duration of the Acceptance stage, described by the TELIP model, and it should simulate at an accelerated pace, the processes that would normally take place at the workplace. In order to facilitate people to rapidly assimilate new knowledge and develop new skills, the TC should provide them with a theoretical background from university researchers and practical know-how from a support person of industry.
Collaboration between university and industry is critical in curriculum development, in order to prepare learners for real-world conditions [42]. An industry partner can help make the curriculum relevant to industry expectations and provide learners with professional expertise, giving thus credibility to the curriculum [42,43]. University-industry collaboration can help ensure that learners are provided with employability skills that increase the individual's ability to secure and be successful in a job of their choice, making them thus more employable [44,45]. In the context of this paper, university-industry collaboration allows for the integration of the university researchers' theoretical knowledge about ETs with the industry experts' practical know-how.
The main goal of the paper is to design and validate two different training formats that, in the university-industry partnership, utilize the unique knowledge and experience of the university researchers and industry experts, in order to lead learners through the ET IP Awareness and Acceptance stages. The study design makes use of two research phases, built on each other: (a) in the first phase (Phase 1) a two-day workshop is conducted with the goal of increasing university students' understanding about a certain ET, Artificial Intelligence Enhanced Robotics (AIER), using the example of two educational AI-enhanced robots; and (b) in the second phase (Phase 2), based on the data from Phase 1, an eight-day TC is designed and conducted, using the UR3e robotic arm as an example of AIER.
In both of the phases the knowledge from two professional communities-university researchers and industry experts-is synthesized with the aim of encouraging learners to experiment with AIER devices and with new methods that are needed for constructing a basic understanding and positive attitudes towards AIER. University members (innovation and robotics researchers; adult learning didactics; sustainable development experts; philosophy professors) were playing an active role in the process of constructing participants' understanding and attitudes, by providing the methodological, didactical and technological expertise. Industry experts were supporting the study with their specific knowledge about the everyday practical aspects of using AIER devices. Based on the notions above, we have formed the following Research Questions (RQs) to guide our study phases: Phase 1 (Section 3) is guided by RQ1: Is workshop an appropriate training format for leading people to and through the AIER innovation process Awareness stage in a way that ensures learners' positive future expectations towards AIER?
Phase 2 (Section 4) is guided by RQ2: Is training course an appropriate training format for leading people to and through the AIER innovation process Acceptance stage in a way that prepares learners to accept AIER-enhanced jobs?

AI-Enhanced Robotics
AI is a combination of hardware and software (algorithms) that allows a machine to exhibit an intelligent behavior, i.e., to exploit an animal-like intelligence. Modern AI is often able to reason, build knowledge, plan, learn (including human language) and perceive. In recent decades, some AI solutions have been able to perform complex movements and manipulate objects, similarly to humans.
AI could potentially allow machines to exhibit features similar to humans-for example, manipulate information (remember, reason, plan or learn), use human language for communication, perceive, make complex movements and manipulate objects, fuzzy behaviors and decisions. The combination of AI and robotics make it possible to exploit the approach of Embodied Cognition (EC), an idea that for higher intelligence, some aspects of the body, especially perception and movement, are needed [46]. The advances of both AI and robotics have made it possible to meaningfully combine AI with robotics. On the one hand, this provides AI with input systems (touch, sight, and hearing) and output systems (moving limbs, communication) of a robotic body. On the other hand, advanced AI allows a robotic body to exhibit complex movements and behaviors, similar to biological bodies. An example of anthropomorphic or zoomorphic robots that employ AI for their movement and behavior, is the Boston Dynamics' Atlas robot that is able to conduct complex human movements, such as parkour [47]. With their human-like properties, AIER is often perceived as a threat to human existence [17,18,48], or at least capable to infiltrate human society, changing remarkably the ways work is done or how people communicate with machines and each other [49][50][51]. As AIER is also one of the ETs that most people are aware of, it is a suitable testing ground for approaches that provide people with the necessary knowledge for their future lives.

Phase 1: Workshop "My Future Colleague Robot"
The goal of Phase 1 was to bring learners that had no previous experience with A to the AIER IP Awareness stage, meaning that they would become aware of the tec ogy, construct a basic understanding of its opportunities and challenges, acquire ele tary AIER-related skills, and would be ready to move on to the Acceptance stage quired by their future career choices. According to the TELIP model, the natural dur of the Awareness stage can be rather short, starting from only a couple of days [26] used the workshop learning-teaching format, as it matches these requirements: it can vide a basic understanding of the technology, allows a hands-on approach for develo basic skills, and has a potential duration of a few days.

Phase 1: Workshop "My Future Colleague Robot"
The goal of Phase 1 was to bring learners that had no previous experience with AIER to the AIER IP Awareness stage, meaning that they would become aware of the technology, construct a basic understanding of its opportunities and challenges, acquire elementary AIER-related skills, and would be ready to move on to the Acceptance stage if required by their future career choices. According to the TELIP model, the natural duration of the Awareness stage can be rather short, starting from only a couple of days [26]. We used the workshop learning-teaching format, as it matches these requirements: it can provide a basic understanding of the technology, allows a hands-on approach for developing basic skills, and has a potential duration of a few days.

The workshop took place in February 2021. The workshop's concept is graphically illustrated in Figure 4.
The workshop's first day consisted of four main sessions: (a) a short overview of robotics, AI, and studies about people's attitudes towards robots; (b) a demonstration of the Poppy Ergo Jr robot and its capabilities; (c) a hands-on session for the participants to experiment with the Poppy Ergo Jr robot, and (d) a more thorough overview about the Poppy Ergo Jr robot.

Similarly to the first day, the sessions (a), (b) and (c) were conducted by university researchers, and session (d) was conducted by the developers of the Clearbot robot.

Data Collection and Analysis
Before and after the workshop we asked the workshop participants to argue in free form text how they see robots in their personal and work lives after 10 years from now on. For this we used an online survey with two sets of questions: 1. Please describe what role, in your opinion, the intelligent robots will play at your workplace after 10 years. Do you see them as friends, colleagues or tools? 2. Please describe what role, in your opinion, the intelligent robots will play in your personal life after 10 years. Do you see them as family members, friends, slaves or tools?
We used the quantitative content analysis method with closed coding [54] to analyze the submitted information. The closed codes used for coding were the following: robots perceived as (a) tools; (b) colleagues; (c) friends; (d) advanced tools; (e) servants; and (f) family members. In addition, the participants were asked to give post-workshop feedback as an essay via email about their previous contact with AIER, the workshop content, its influence on themselves, and to share their thoughts about improving the workshop so it would be more useful in introducing AIER to different target groups. We used interpretative phenomenological analysis [55] to analyze the content of the essays. Two general categories were generated first: (a) a participant's previous experience with AIER and (b) a participant's self-observed improvement of their skills, knowledge, self-confidence and interest. Based on these categories we made an initial review of the essays and developed codes for each category. Next, we analyzed the essays again, and marked the presence of codes in the texts, counting each code once per participant's essay.
The data coding was conducted by two researchers in order to account for personal biases that could have had an impact on findings [56]. In the interests of coding reliability, The workshop's second day took place two weeks after the first one and had a similar structure: (a) a short overview about the robotics-related global challenges, influence on environment and society; (b) a demonstration of the Clearbot robot and its capabilities; (c) a hands-on session for the participants to experiment with the Clearbot robot, and (d) a more thorough overview about the Clearbot robot.

The coding followed the guidelines given for situations where calculating inter-rater reliability is not desirable [57].

Sample
The workshop participants were 16 university students of masters and bachelor's degree level (nine male and seven female, 20 to 50 years old with an average age of 33), from the fields of social sciences, educational sciences and computer sciences. Of these participants, 16 persons filled in the online query about the AIER's possible future roles, and nine persons submitted their feedback essays for the workshop (n = 9).

Results
Our first research question was "Is workshop an appropriate training format for leading people to and through the AIER innovation process Awareness stage in a way that ensures learners' positive future expectations towards AIER?" To answer this question we examined the participants' responses to the online survey and their essays.
The responses to the online survey questions were analyzed in order to find out how the workshop influenced the participants' perception of AIER (Table 1). At the workplace, the AIER was perceived relatively neutrally: as tools (62% of answers, 18% increase), colleagues (54%, 9% decrease); friends (38%, 7% increase). At homes, the robots were considered useful as (advanced) tools (92%, 4% increase), servants (38%, 13% increase), and friends (23%, 2% decrease). There were no participants who would consider AIER as their family members. These numbers allow us to suggest that the workshop improved the participant's understanding of AIER. The content of the essays revealed the following information ( Table 2). Most of the participants had no previous meaningful contact with AIER. For 56% this was their very first contact with this ET (e.g., "At the very first meeting, I felt a little awkward, because although I am interested in any field of IT, etc., my knowledge is still quite poor."), while 11% of them (n = 1) had some previous experience (e.g., "I've been in contact with learning robots a bit before, but I saw and tried such a robot hand for the first time."). The growth of self-confidence as a result of the workshop was noticed by 78% of the participants (e.g., "The workshop was actually very cool. I liked that we could actually experiment with Poppy, and I got the reassurance that you don't have to be a certified engineer to perform such simpler functions."). 78% of the participants also observed the growth of their understanding about AIER (e.g., "Everything was clear. Personally, I had thoughts about what could be done with this robot, that is, the feeling that a robot like this robot would allow me to do more vital things in the future."). 33% of the participants became inspired to learn more about AIER, and also 33% of the participants contemplated about the possibilities of using this ET by themselves.

Discussion
The feedback from the participants suggests that the workshop helped them to improve their understanding of AIER and cultivated rational and realistic attitudes towards this ET. The workshop format, if properly conducted, creates interest in AIER and desire to further experiment with it-but does not influence everyone in the same way. In our investigation, only a third of the learners were interested in learning more about AIER-a reasonable share, considering that most of our participants were from the humanitarian areas. However, a great majority of the participants became more self-confident and knowledgeable about AIER, indicating that the workshop had been successful in creating positive awareness about AIER.
In conclusion, these developments indicate that the workshop format we developed could be considered, after further improvements, to be suitable for bringing a learner to the ET IP Awareness stage. A properly prepared and conducted workshop can ensure learners' positive attitudes towards AIER and help them to become self-confident about their skills and knowledge, related to the ET. However, it is only in the Acceptance stage where the learners shape their conviction about their abilities to really use technology in their daily work routines. So while the workshop format could give some initial enthusiasm and understanding of the overall features of the technology, more is needed for preparing people to accept ET-enhanced jobs. It is the Acceptance stage where the learners make a personal decision about the usability of a technology in their job routines. In order to encourage learners, including this 67% of the learners in the workshop who were not interested in further experimenting with AIER, to start considering AIER-related future careers, we consider it necessary to guide them through the simulated Acceptance stage. For this, it is necessary to give people self-confidence in their ability to cope with technology when the situation calls for it (see also [58]). However, due to its short duration, the workshop format is not able to provide enough hands-on time for experimenting with the devices and constructing a comprehensive understanding of the technology. In addition, in the Acceptance stage learners need to be provided with a suitable framework that allows them to coherently organize their newly constructed knowledge, in order to make it usable. This framework includes knowledge about the technology and aspects related to it, about the possible usage contexts, but also about the proper methods of learning this technology.

Phase 2: Training Course "My Future Colleague Robot"
The results of Phase 1 gave valuable input for designing a full-length TC for adult learners. We concluded that for various reasons the workshop format could be inadequate when the goal is to guide learners through the Innovation Stage Acceptance stage-mostly because its duration is too short to develop realistic skills for using a complex ET, such as AIER. The TELIP model suggests that depending on the complexity of a technology, its IP Acceptance stage can last from a month to a couple of years in real-life settings [26]. We propose that it is possible to use an intensive TC to adequately simulate the Acceptance stage during a much shorter time. Therefore, the goal of Phase 2 is to establish whether a full-length TC could be used to guide learners through the IP Acceptance stage.
There are indications that the transition of learners from the Awareness stage to the Acceptance stage requires the learners to become convinced about the usability of technology in real-life situations ( [59,60], as also noted by [24]). However, in the Acceptance stage, the learners develop their opinion about the usability of the technology in their own particular everyday routines. So while the task of the Awareness stage is to encourage learners to start experimenting with a technology, the task of the Acceptance stage is to incline learners to accept the technology as one of their regular work tools. In the Acceptance stage, the learners use the technology regularly in their work routines, although they have not yet developed proper usage methods, lack knowledge and skills to efficiently exploit the opportunities that the technology offers, and often need a support person to help them [60]. These notions indicate that TC that simulates the Acceptance stage should include as much as possible real-life hands-on experience, constant support-even for the independent work, but also additional information that helps learners to construct an adequate point of view on the technology.

Training Course Description and Implementation
A full-length TC was designed with the goal of introducing AIER (based on the example of the collaborative robotic arm UR3e) to persons active in the labor market, to help them to develop the basic set of skills needed to operate this robot and to encourage them to form positive attitudes towards AIER and jobs that include such ETs. One of the particular goals is to help participants to reach the level of self-confidence that would make it easier for them to accept future jobs, enhanced by AIER, and prepare them for job interviews where employers seek to confirm skills instead of checking credentials [61].
The TC was divided into eight contact days (five academic hours per day, 40 h total) that were dispersed over 6 weeks (Figures 5 and 6). This iterative nature should lead to the accumulation of the participants' knowledge, improvement of their skills, and shaping their positive attitudes towards AIER. The duration of the course considers the TELIP model ( Figure 1) offered by [26]) and is sufficient for the participants to pass the AIER IP stages of Awareness and Acceptance and to become prepared to enter the Adoption stage if offered an AIER-enhanced job.
The TC was implemented in the spring of 2021 when it was offered as a regular adult distance training program (worth 2 ECTS credit points) jointly by the Tallinn University's School of Educational Sciences and a limited liability company Demek CNC.
The contact days were conducted as distance learning sessions via the Zoom videoconferencing software. In addition, the participants were allowed to schedule individual in-person meetings in order to get hands-on experience with the UR3e robotic arm. The typical contact day consisted of the following sessions: (a) coaching about adult learning; (b) general information about robotics and AI; (c) general information about the influence of robots on society, environment and sustainable development; (d) demonstration of the UR3e robotic arm; (e) information about using and learning specific types of robots, their use scenarios, usage safety, etc.; (f) teamwork on developing potential usage scenarios in participant's current and future jobs, and (g) sharing and discussing teamwork results, joint construction of understanding about the topics of the contact day. The sessions (a), (b) and (c) were conducted by the university researchers; the sessions (d) and (e) were conducted by the industry experts, and sessions (f) and (g) were guided by the university researchers. The contact days were followed by the periods when the participants designed independently (in total 12 estimated academic hours) possible usage scenarios for AIER and related processes and developed further their knowledge and skills by using an online simulation environment eSeries Core Track (https://academy.universal-robots.com/freee-learning/e-series-e-learning/e-series-core-track/, accessed on 11 November 2021).
The TC was divided into eight contact days (five academic hours per day, 40 h total) that were dispersed over 6 weeks (Figures 5 and 6). This iterative nature should lead to the accumulation of the participants' knowledge, improvement of their skills, and shaping their positive attitudes towards AIER. The duration of the course considers the TELIP model ( Figure 1) offered by [26]) and is sufficient for the participants to pass the AIER IP stages of Awareness and Acceptance and to become prepared to enter the Adoption stage if offered an AIER-enhanced job.  The TC was implemented in the spring of 2021 when it was offered as a regular adult distance training program (worth 2 ECTS credit points) jointly by the Tallinn University's School of Educational Sciences and a limited liability company Demek CNC.
The contact days were conducted as distance learning sessions via the Zoom videoconferencing software. In addition, the participants were allowed to schedule individual in-person meetings in order to get hands-on experience with the UR3e robotic arm. The typical contact day consisted of the following sessions: (a) coaching about adult learning; (b) general information about robotics and AI; (c) general information about the influence of robots on society, environment and sustainable development; (d) demonstration of the UR3e robotic arm; (e) information about using and learning specific types of robots, their use scenarios, usage safety, etc.; (f) teamwork on developing potential usage scenarios in participant's current and future jobs, and (g) sharing and discussing teamwork results, joint construction of understanding about the topics of the contact day. The sessions (a), (b) and (c) were conducted by the university researchers; the sessions (d) and (e) were conducted by the industry experts, and sessions (f) and (g) were guided by the university researchers. The contact days were followed by the periods when the participants designed independently (in total 12 estimated academic hours) possible usage scenarios for AIER and related processes and developed further their knowledge and skills by using an online simulation environment eSeries Core Track (https://academy.universal-robots.com/free-e-learning/e-series-e-learning/e-series-core-track/, accessed on 11 November 2021). Compared to the measures we conducted with the workshop, we now focused on greater detail on certain aspects of the TC. For example, due to the facts that (a) the participants were employed adults; (b) the taught AIER was a real industrial robotic arm; and (c) the TC aimed at developing knowledge and skills needed at actual workplace situations, the participants were asked to evaluate skills and knowledge about this ET and about the UR3e robotic arm. In addition, we were interested in getting a better overview of the effectiveness of the training components.

Data Collection and Analysis
We used an online survey with four closed questions with 6-point Likert scales and a multiple-choice question, to gather data about participants' attitudes towards TC, AIER, and their future outlooks about using this ET in their current and future workplace. The questions were the following: A. Items about the participant's feedback on the training course performance, with Likert rating scale from 1 (strongly disagree) to 6 (strongly agree): • Did the training content match your expectations? • Please rate how much do you know about using the UR3e robotic arm?

Introduction of the world of robotics The role of robots in shaping a sustainable world Ethics aspects of using robots Demonstrations of the UR3e collaborative robotic arm Work safety with collaborative robots The data processing and analysis were conducted jointly by two researchers in order to preclude possible data handling errors and to account for possible personal biases [56]. The participant's answer was considered positive if its rating value was higher than 3 (out of 6).

Sample
The TC targeted small-office and home-office employees, non-profit organizations and unemployed persons. Of the 17 participants, 14 were employed, two were unemployed and one was a university student; 13 participants were male, four were female. The age of the participants was not recorded. The participants were guided by four university trainers (experts of educational robotics, adult learning and sustainable development) and 3 industry experts. The surveys were filled in by 10 participants, of these seven were employed, two were unemployed and one was a university student. Half of these persons were looking for a job or for a new professional challenge.

Results
Our second RQ was: "Is training course an appropriate training format for leading people to and through the AIER innovation process Acceptance stage in a way that prepares learners to accept AIER-enhanced jobs?" While 70% of participants received the TC positively (e.g., "The training was very instructive, when considering the future"), the rest of the results leave room for discussion (Table 3). More than half of the participants managed to construct usable knowledge about the UR3e robotic arm and became able to offer suggestions for using the robotic arm in their work (e.g., "25+ years of experience in industrial automation, as a physicist I can usually offer something practical"), and about half of the participants considered their knowledge about the robotic arm as adequate (e.g., "On a daily basis, I work largely with the industrial sector, as well as with other companies in the field, where robotization is extremely important. Knowledge about the robot-hand's logic allows me to have longer dialogues."). In addition, 30% of the participants were able to connect what they learned with their current work or activities (e.g., "I made the final assessment already for my everyday work."), while 60% were doubtful about it (the rating value was 3 out of 6).
We also examined, which TC modules were considered necessary by the participants (Table 4). Of the modules that the participants valued the most (80%) "The role of robots in shaping a sustainable world" explained the impact of robotics on human society and the environment and described related challenges. Additionally, the modules "Demonstrations of the UR3e collaborative robotic arm" (70%) and "Introduction of the world of robotics" (50%) were considered necessary. It is interesting to note that for the participants the modules about work safety and ethical aspects of using robots were not considered as important (respectively 30% and 40% of the learners).

Discussion
The experience and feedback from designing and conducting an AIER workshop (Phase 1) helped us to design a TC (Phase 2) that largely met the participants' expectations (average rating value 4.2 out of 6) and helped more than half of the participants to acquire necessary skills and knowledge to operate the UR3e robotic arm. However, it is more difficult to assess whether the TC fulfilled the goal of guiding learners through the AIER IP Acceptance stage in a way that they would be ready to move instantly to the Adoption stage in their next job-or if the TC encouraged them to start looking for AIER-enhanced jobs. Our previous experience [60] indicates that the transition from the Acceptance stage to the Adoption stage happens when learners become convinced about the overall positive effects of the technology on the outcomes of their work. In addition, learners need to build sufficient self-confidence in their skills and knowledge that are needed to use the technology-in order to become able to independently work with the technology and further develop their technology-related skills and knowledge.
The results of Phase 2 indicate that half of the learners developed skills and knowledge to use AIER independently and became convinced about their ability to offer recommendations for using AIER in their workplace environment. At the same time, the gathered data also indicates that not all of the learners were able to further develop their newly acquired skills and knowledge at their present workplace, meaning that these would fade in time [62], while, hopefully, the acquired self-confidence will encourage the learners (see also [58]) to overcome their insecurities and consider accepting jobs with AIER involvement. In addition, we need to study why the need for some of the modules, such as ethics and workplace safety, was rather low. One of the reasons could be in the fact that most of the participants were already working in technical jobs where they could have already received similar training and had, therefore, no further need for these modules-but we need to clarify if there are also other reasons.
The TC was originally planned as an in-person TC. Due to the restrictions of the COVID-19 era, we chose the distance model very early, without a clear understanding of the ramifications of this choice. This could have influenced the TC results negatively, despite the possibility of independently experimenting in-person with AIER, and of the availability of well-developed simulation tools, such as the eSeries Core Track software that we used. We also need to study if the low scores (rating value < 3) from a few individuals could have been caused by the lack of previous general technical experience, by using the distance learning approach, or by something else that did not allow us to properly address the interests of the specific learner group.

Conclusions
The 21st century is characterized by the rapidly changing meaning of the nature of work. Low-skilled jobs are being wiped out and advantage is given to the people with good skills in ETs. Literature indicates that virtually all CEOs tend to believe that ETs will have a disruptive impact on their companies and most of them find their organizations lacking skills to adapt [62]. Studies have shown that there is a significant positive link between higher skill levels and productivity [63]. The demand for skilled workers is growing, with employers globally struggling to find workers with the right mix of technical skills and human capabilities [64] and leading to a situation where "for the first time in a generation, workers are gaining the upper hand" [65]. This upper hand makes it easier for workers to become employed but on the other hand, it points at an urgent need for retraining people, to adapt to the emergence of new technology, new jobs, and even new language, amplified by the fact that the half-life of skills is falling rapidly [64]. These requirements pressure workers to become flexible and curious, with a positive outlook on lifelong learning, as these characteristics enable them to continuously learn new skills in order to retain their position in the labor market [3]. The problem of retraining people to adopt ETs is felt on the level of business organizations where many modernization attempts fail, as innovation process planners do not possess models that would provide a clear understanding of how to achieve adoption goals-resulting in progression from one ET IP stage to another becoming almost uncertain [66].
The purpose of our study was to contribute to this gap in the job market of needing more people with skills and knowledge about ETs by offering training approaches that take into account the three-stage nature (Awareness → Acceptance → Adoption) of the ET innovation adoption process. The time-dependent nature of the end-user needs during the IP stages is pointed out by [35] who recommend providing people with adequate information during the different IP stages, using different approaches. In addition, [67] confirms that adoption outlooks improve when the adopters are timely supported with appropriate information by (in the case of Brazilian agriculture) their younger, more digitally literate peers during the IP stages that correspond to the TELIP model's Awareness and Acceptance stage.
We chose AIER as an example of ETs and proposed and developed two different approaches that were designed to introduce AIER to people of different previous backgrounds with the aim of providing them with necessary skills, knowledge and positive attitudes that would encourage them to accept and seek AIER-enhanced jobs.
First, we focused on the workshop approach, assuming that the workshop format is more appropriate for people with minimal previous knowledge about AIER. The aim of such a workshop would be to guide people to and through the IP Awareness stage, providing them with some basic skills to work with AIER, and a general understanding of AIER and opportunities and problem areas related to it. This approach is also supported by [67] by suggesting that workshops and other short networking events during the Knowledge stage (corresponds to the TELIP's Awareness stage) greatly influence the technology adoption rates.
Our results confirmed that workshops can be used for introducing AIER as in our case the learners became more interested in AIER and developed realistic positive attitudes towards it. This confirms the observations by [39], who described the creation of end-user awareness about the technology and its abilities during the IP Awareness stage (corresponds to the TELIP's Awareness stage). However, due to their limited format, workshops might not be suitable for training people who need to construct a more thorough and systematic understanding of an ET and develop skills needed for using this ET, especially if more complex technologies are considered.
Based on the feedback from the workshop approach we developed a TC with the purpose of providing learners with a realistic functional environment for them to construct a usable framework of knowledge and skills for using a certain AIER-the UR3e robotic arm. Our goal was to simulate workplace use of the robotic arm in a way that would support the learners to pass the IP Acceptance stage, helping them to become convinced about the feasibility of AIER and about their ability to use AIER in a real-life workplace. Our results prove that the TC approach, described in Phase 2, is suitable for many adult learners. The authors of [39] similarly highlight the need to provide end-users during the Consideration stage (corresponds to the TELIP's Acceptance stage), with more detailed knowledge-in their case with written materials and demonstrations of the functionality of the technology. Similar micro-credential [68] training courses could enable people to apply for jobs where in-depth training takes place in the workplace and give them an idea of what lies ahead. The duration of a TC should depend on the complexity of the studied technology, available funding resources, availability of participants and on their readiness to participate in a long-term adult TC and could be shortened if the content is provided in a more intensive manner.
This paper represents a pilot use of the TELIP model outside the educational context. The model was used to examine learning of ET related skills and knowledge through the prism of the IP stages, designing appropriate approaches for initiating and passing the Awareness stage and the Acceptance stage, to estimate the impact of the conducted workshop and TC on learners, and to evaluate their transition between the different IP stages. The TELIP model (Figure 1) allows addressing the appropriate IP factors that determine whether the outcome of the IP stage leads the innovation closer to becoming sustained in the end-user's practices. In this pilot study, these factors were not considered, and this may be one of the reasons why the TC did not yield perfect results. In future work, we plan to consciously exploit the IP factors, in order to ensure better outcomes of future training courses.
In order to start using ETs, including those that could support achieving the Paris Climate Accords targets, a large portion of the population should become ready to start using these ETs, for example, by passing relevant training courses at their workplaces. Wellplanned workshops and TCs that are based on scientific models can save valuable resources, including working time. In addition, such training can be used for discovering challenges, barriers and immaturities of technologies, but also for highlighting opportunities and benefits in certain sectors, and therefore, can be used for accelerating the introduction of ETs in these sectors. The unexpected COVID-19 crisis demonstrated clearly that the necessity for implementing ETs can arise with great urgency. Without proper preparation, the people are unable to meaningfully take full advantage of the opportunities ETs offer. This pilot study represents but one necessary step towards the goal of providing the population rapidly with skills and knowledge that are needed with the ETs that have abruptly become unavoidable.

Limitations and Future Work
The piloting nature of this study determines the main limitations of the study (small sample sizes in both research phases, its data analysis methods, lack of triangulation). We plan to repeat the study after the end of the COVID-19 restrictions with a larger sample that consists of people from different countries. For collecting data we plan to design and validate a more precise tool that would incorporate both quantitative and qualitative approaches.
We also need to supplement the TELIP model and to develop clearer criteria for identifying the transition between the different IP stages. In this study, we simulated workplace settings of the Acceptance stage. In the future, we plan to exploit the universityindustry collaboration approach and implement real-life workplace settings to TC, in order to better represent the context of the potential use of AIER. In addition, it is necessary to examine further whether the innovation adoption sustainability after the simulated IP Acceptance stage is similar to what is achieved through a more natural means (e.g., learning at the workplace).
As the literature offers similar three-stage models (although with less attention on the factors that influence the innovation process during the different stages), tested in different contexts, we consider, in collaboration with relevant science teams, developing the TELIP model to a more generalizable model in the future. This future model could be used as a guiding framework by the representatives of various organizations that currently struggle to prepare themselves for the future.
