Impact of the Pandemic on STEAM Disciplines in the Sixth Grade of Primary Education

The demand for professionals entering the labor market requires knowledge and disciplines in the areas of Science, Technology, Engineering, Art and Mathematics (STEAM). Schools are the first link to train competent students for today’s society. However, the pandemic has conditioned the teaching–learning methodologies based on promoting STEAM in educational centers, which is the reason that leads us to carry out this study. The main objective of the research is to evaluate the STEAM dimensions in the sixth grade of primary education in times of pandemic. The study method is based on a quasi-experimental, descriptive and correlational design with an experimental group and a control group. The data are collected through a validated questionnaire, pre-test and post-test, which develops an assessment of student collaboration in STEAM activities. The sample is made up of 142 Spanish students, of which 68 belong to the control group and 74 to the experimental group. The conclusions of the study highlight that the active methodologies, based on computational thinking and on makerspaces of the future classroom, influenced the STEAM dimensions of the experimental group before the pandemic. However, the pandemic and the health restrictions in face-to-face classes led to a negative assessment of the experimental group in the STEAM dimensions.


Introduction
Information and communication technologies (ICT) in education are used more frequently as an online communication and collaboration channel between teachers and students; however, after COVID-19, their use has accelerated. Even Ref [1] points to this era as the fourth industrial revolution, where it is necessary to cultivate creative convergence talents that can deal with uncertainty and coexist with technology. Teachers and students have adapted to new learning with social distancing, and the demand for new teaching methods is growing in the educational field [2]. Social changes and technological advances impose changes in the teaching and learning models. There is a factual need to incorporate new methodological approaches [3] that enhance creativity, the ability to solve problems and the development of new digital skills in students [4,5]. In this sense, ICTs stimulate positive responses in students and favor their attention toward the areas of Science, Technology, Engineering and Mathematics (STEM) [6,7], especially when they work in a transversal and integrated way at the curricular level [8].
STEAM approaches incorporate the (A) of arts and creativity in education in the term STEM [9,10]; in this way, learning is more integrated, meaningful and attractive for students [11]. It is a relatively new construction in education [12] and can be improved through specific educational programs [13]. STEAM increases interest in pedagogical approaches that can bring new methods for innovation in society [14]. STEAM in education (STEAM-EDU) allows cultivating talented students and meeting the demand for professions in today's society [15] linked to the use of technological devices and tools, such as engineers, programmers, computer scientists or project leaders [3,16]. For this reason, the educational field must be the axis and the base of the world economic future in view of the emerging skills needs of the labor market [17] and must adopt anticipatory strategies in education [18]. However, there is little research on STEAM-EDU teaching methodologies and resources among teachers [19,20].

STEAM Disciplines in Education
This study investigates different STEAM-EDU disciplines and areas, including multidisciplinarity, interdisciplinarity and transdisciplinarity [21][22][23]. These disciplines have an impact on skills, such as linguistics or mathematics [24,25]. In addition, notable effects on the learning attitude, motivation, confidence, student success and relationships between students and teachers are evident [26][27][28]. STEAM-EDU confirms that a student can conceive of more than one discipline occupying the same school hours and curricular space [29].
Other STEAM-EDU-related disciplines within the scientific literature are peer interaction and problem solving, in which STEAM-EDU has a dominant influence [30]. In this sense, social development and project or team work enable real-world learning through inquiry, collaboration and positive communication in the classroom [31][32][33][34]. Critical thinking plays an important role in this process [31,35], which allows students to interact and self-assess using digital technology. Learning is facilitated when all students, more or less experienced, organize their work in a way that allows all participants the opportunity to see, discuss and engage in problem solving and shared practice [36].
One way to develop these STEAM-EDU skills are teaching methodologies aimed at learning based on problems, projects and collaborative, experiential and playful learning [37]. Physical spaces, learning and emotional elements also influence academic results in schools [1]. However, the impact of collaboration and communication skills is still low [30]. To this fact, it must be added that in recent years, the relationship and interaction between pairs of students as a result of the COVID-19 pandemic have caused educational systems to accelerate the use of technologies to relate, inserting the R of reflective learning [11], that is, STREAM. In addition, this method merges reading, writing and arts to connect the four STEM disciplines [37]. Students have a positive perception of digital platforms due to the availability of comments and quick access to learning materials [38].

STEAM-EDU and Computational Thinking
STEAM-EDU develops computational thinking skills at an early age [39], understood as the ability to formulate and represent problems to solve them through the use of tools, concepts and practices of the computer science discipline, such as abstraction, decomposition or use of simulations [40]. There are multiple fields that allow STEAM-EDU to work through computational thinking, such as robotics [41,42], block programing or artificial intelligence, which favor student problem solving [43,44] with benefits for the development of creative thinking [45,46]. Computational thinking "is acquiring great importance due to the evolution of new technologies, thus creating a global trend that considers programming in the classroom as a fundamental activity of the present and the future" [47] (p. 45). In addition, "it is currently considered one of the most demanded skills and, hence, its approach in the educational context" [48] (p. 1).
This fact has not gone unnoticed in the Spanish educational policy, which has published at the beginning of the year 2022 a new curriculum and included computational thinking in the Royal Decree 157/2022 of Primary Education [49], specifically in the area of knowledge of the medium, as a method to "decompose a problem into simpler parts, pattern recognition, model making, selection of relevant information and the creation of algorithms to automate processes of daily life" [49] (p. 24415). It also introduced computational thinking into the area of mathematics as one of the key skills in the future of students ("this thinking should be specifically trained and developed with guided methodologies and strategies" [49] (p. 24488)). The use of information technology and computer programs in the areas of education could be an effective movement to awaken vocations in young people who are more deeply involved in engineering, modeling, robotics, programing skills, artificial intelligence [50,51]. However, computational thinking should be understood as a support or methodological means for students to learn curricular content from different areas or subjects while learning digital skills [52].
Currently, computational thinking in schools is imperative for innovation but with knowledge and skills among educators and professionals [53]. Teachers should address student interest generated by STEAM by reference to prior knowledge and use collaborative tools, tutorials, materials and methods that mimic the real world through meaningful learning [54,55], that is, "know how". However, it is necessary that the teachers themselves possess knowledge and skills in the use of technological resources and active methodologies [56,57].

Makerspaces and Future Classroom
The experimental group present in this research integrates makerspaces into their educational projects, that is, spaces to encourage creativity and collaborative learning through STEAM-EDU [58,59]. These spaces prompt students to improve their knowledge using collaborative learning and technology, unlike the traditional method [60]. In these spaces, students imagine, explore, experiment, test, manipulate, discuss and speculate [45]; these actions favor learning through projects and discovery. In addition, the use of STEAM-EDU together with ICT tools is useful to combat school failure, attend to diversity, encourage reading and promote inclusion [61,62]. Active methodologies together with adapted spaces provide meaningful learning that increases student motivation and participation, facilitating the acquisition of content and knowledge in a gamified and playful way [63].
From the European Schoolnet in Brussels, these makerspaces, called the Future Classroom Lab, have been promoted since 2012 with the aim of inspiring practicing teachers to rethink education and adapt their spaces in order to understand how they can positively impact student performance [64]. In Spain, the National Institute of Educational Technologies and Teacher Training (INTEF) and the different departments of education implement Classrooms of the Future (Figure 1) to provide support and training to teachers and educational centers. According to INTEF [65], learning spaces terms are: research, interact, explore, develop, create and present. The rise of makerspaces means that schools themselves are integrating these spaces into their educational plans to share resources and knowledge among students, motivating them to be thinkers, creatives and critics, as well as problem solvers, excellent communicators and collaborators [66]. The centers take into account the organization of learning spaces, the socio-emotional skills required for teamwork and projects, programing and designing activities [67]. Additionally, the spaces allow students to build, invent and establish relationships with all kinds of tools and utensils, such as 3D printers [6].

Justification and Objectives of the Study
The pandemic situation due to COVID-19 in March 2020 motivated all countries to adopt extreme measures to prevent the spread of the virus. In a few weeks, the educational systems changed and adapted their methodologies to the health regulations [68]; even face-to-face classes were suspended. In the Spanish context, schools resumed face-to-face In the decade of the digital age and STEAM labor demands, organizations must adapt policies and infrastructure that allow continuous improvements of educational processes [3].
As STEAM-EDU is gaining popularity in K-12 schools, student assessment is needed to identify the most influential dimensions [46]. This reason leads us to the present study on peer interaction, collaboration, communication, research and transdisciplinary thinking in problem solving offered by STEAM after the emergence of COVID-19.

Justification and Objectives of the Study
The pandemic situation due to COVID-19 in March 2020 motivated all countries to adopt extreme measures to prevent the spread of the virus. In a few weeks, the educational systems changed and adapted their methodologies to the health regulations [68]; even faceto-face classes were suspended. In the Spanish context, schools resumed face-to-face classes with prevention, hygiene and health promotion measures against COVID-19 imposed by the Spanish Ministry of Education and Health [69]. Among the most outstanding measures was the decrease in student ratio, i.e., no more than 15 students per classroom. The use of masks was also mandatory, and the use of the center's dependencies, meetings and assemblies between teachers and students was prohibited, and the minimum distance was 1.5 m between the students. They could also not share school supplies. In addition, there were 14-day lockdowns on students in the event they tested COVID+ or had close contact with a positive person.
Taking the theoretical framework as a reference, the possibility of carrying out cooperative activities among students was limited to digital platforms, videoconference applications, email. In this way, the students lost the possibility of fully benefiting from all the advantages of collaborative learning and experimentation. In addition, it caused a disadvantage in unfavorable sociodemographic environments [70]. This fact has generated in the educational field the need related to the use, learning and mastery of ICT [71]. Interdisciplinary projects with STEAM methodology after the pandemic can create a global and real vision of the knowledge that can be imparted in teaching [72]. In this sense, the COVID-19 pandemic must be used as an opportunity [70]. This reason leads us to investigate how the STEAM disciplines have been affected.
As a result of this situation, this research arises to expand knowledge about the impact that the pandemic has had on the STEAM-EDU disciplines in the primary education stage. We analyze and compare the different STEAM-EDU disciplines between a control group and an experimental group, the latter integrating computational thinking and the Classroom of the Future into its educational plans.
The main objective of this research is to evaluate the STEAM dimensions in the sixth grade of primary education in times of pandemic. There are five STEAM dimensions under study: Peer Interaction (PEER_INT), Positive Communication (POST_COM), Multiple Options (MUL_PATHS), Focus and Tasks (AA_TASK), Transversal Thinking (TRANS_THINK).
In addition, this general objective leads to the formulation of the following specific objectives: • Compare how working with STEAM-EDU influences each of the dimensions of the study before the pandemic using different methodologies.

•
Know the impact that the COVID-19 pandemic has had on STEAM disciplines.
Based on these objectives, the following hypotheses arise: • H1: STEAM-EDU disciplines before the pandemic are more effective with an active methodology based on computational thinking and with makerspaces compared to a traditional methodology. • H2: STEAM-EDU disciplines during the pandemic are better valued in the experimental group compared to the control group.

Materials and Methods
This research is a study that responds to a quasi-experimental design, with experimental and control groups and descriptive and correlational pre-test and post-test measurements, supported by a quantitative method in data treatment [73]. In order to proceed to a correct performance of the investigation, the study had the considerations of experts in these types of methodologies [74]. In addition, the analysis structure of previously reported impact database studies was followed to carry out a science-validated method [75].
Specifically, during the research process in times of pandemic, the methodologies carried out by both the control and experimental groups were similar to the traditional one due to the restrictions on collaborative work and distancing imposed by the government of Spain ( Figure 2). However, the experimental group before the pandemic used active methodologies based on computational thinking and makerspaces (Figure 3), while the control group used a traditional methodology.

In this study, the final sample is made up of 142 Spanish students, of which 68 belong to the control group and 74 to the experimental group. Six students from the control group and two students from the experimental group were excluded because they did not take the pre-test, the post-test or any of them. The educational center is publicly owned in the city of Ceuta, a Spanish city located in the north of the African continent and with more than 40% of the inhabitants of the Islamic religion [76]. This educational center was selected for including within its educational center project active methodologies based on computational thinking and having Classrooms of the Future with makerspaces, as indicated by the INTEF in its network map of centers in Spain [77].

The control group of students also belongs to the same educational level, the sixth grade of primary education. It was selected because it was located in the same area of influence and constituency as the center of the experimental group in the city of Ceuta, that is, with the same sociodemographic characteristics to avoid bias. The previous analyses carried out in this investigation determined that the control group and the experimental group were equivalent. This fact allowed us to develop the investigation in an adequate way.
The study was carried out through a seminar organized and authorized by the Provincial Directorate of Education of Ceuta, dependent on the Ministry of Education and Vocational Training. In addition, it has the approval of the directors of the educational centers involved in the study, as established in art. 120.4 on the autonomy of centers in Organic Law 2/2006, of 3 May, on Education in Spain [78]. The educational centers have the authorization of the families. The students carried out the study voluntarily and anonymously, and the data processing guaranteed data protection.

Instrument
For the research, a validated co-measure questionnaire was used based on the development of an evaluation of student collaboration in STEAM activities [46], located after a thorough review of the scientific literature.
The validated instrument used is based on the US context and a K-12 sample [46]. In our case, based on the levels of validation and reliability of the questionnaire, we carried out a validation and reliability of the said instrument in the Spanish context, specifically for students in the sixth grade of primary education (Appendix A). In this case, the instrument was translated by two expert translators. Subsequently, a quantitative evaluation was carried out on the original instrument by five experts in the field of STEAM education in Spain. For this, the Fleiss Kappa and Kendall's W tests were performed, which were correct (K = 0.81; W = 0.85) [79].
An exploratory factorial analysis was performed using the quantitative validation method through the main components of the method with a varimax rotation. The dependence between the variables was obtained with the sphericity test (Bartlett = 4221.043; df = 595, p < 0.0001). Additionally, a relevant score was discovered through the Kaiser-Meyer-Olkin test (KMO = 0.811). Finally, the mean reliability of the questionnaire was calculated with various statistical processes, such as the mean variance extracted (AVE = 0.78), Cronbach's alpha (α = 0.84) and composite reliability (FC = 0.81). The results of these values confirm adequate levels of reliability of the instrument used.

Procedure
This study was approved by the ethics committee under code 2292/CEIH/2021, in accordance with the recommendations contained in the Declaration of Helsinki on good research practices. In addition, the study in the educational centers was carried out through a seminar organized and authorized by the Provincial Directorate of Education of Ceuta, dependent on the Ministry of Education and Vocational Training. It also has the approval of the directors of the educational centers involved in the study, as established in art. 120.4 on the autonomy of centers [78] on Education in Spain. The educational centers have the authorization of the families. The students carried out the study voluntarily and anonymously, and the data processing guaranteed data protection.
The research phase was carried out after the confinement caused by the first wave of COVID-19, specifically after the incorporation of students in face-to-face classes.
In the study phase, coinciding with the first week of incorporation of the students after the period of confinement, the researchers proceeded to collect data from the printed pre-test questionnaire that was provided to the students of sixth level of primary education, anonymously and voluntarily. This questionnaire referred to how they worked in faceto-face classes before the COVID-19 pandemic, since the students did not know how the classes would develop with the new normality established by the restrictions and sanitary measures. The researchers were present at the data collection and advised the students at all times.
In the experimental phase, the students of both groups, control and experimental, used the methodologies of their educational plans in person but taking into account the preventive measures mentioned in the justification and dictated by the health and educational legislation in Spain at that time [69]. After a quarter of classes, the researchers repeated the same procedure as the pre-test; this time, it was about collecting data from the post-test sample in relation to the methodology used during that quarter with the sanitary measures and restrictions. In this process, again, the researchers were present in the data collection and advised the students at all times. Finally, once the data were collected, they were transferred to the database of the Statistical Package for the Social Sciences (SPSS V. 25 ). Once the said database was configured, its statistical analysis was carried out.
The pedagogical method developed by the experimental group is framed within the Educational Project of the Center. This group has a methodological line for the entire primary stage, from 6 to 12 years old. Therefore, this group of sixth grade of primary education had worked on computational thinking and in makerspaces from an early age. This methodological line includes four content blocks: the computer and its operation, the internet, audiovisual image editing and computational thinking. In addition, it has the spaces that the European Schoolnet in Brussels and the INTEF advise to promote active methodologies (Figure 4). These zones are: Present, Create, Investigate, Interact, Develop and Explore. This way of working, alternating with the traditional methodology, that is, with the textbook as a guide for the teacher and students, was the work dynamics of the experimental group. Until the arrival of COVID-19 and the return to face-to-face classes, the restrictions only allowed the use of the traditional methodology, and these makerspaces could not be used.

Analysis of Data
To obtain the study data and respond to the objectives, an in-depth analysis was carried out. In the statistical analysis of the research, the mean (M), the standard deviation (SD) and the standard error of the mean (SE) were included. In addition, skewness (Skw) and kurtosis (Kme) tests were included to identify the distribution trend. The coefficient of variation (CV) was also used to find out the dispersion of the response.
These statistics were applied to identify whether or not it was feasible to use the Student's t-test. The Student's t-test (tn1+ n2−2) was used to compare the means between the different groups. Additionally, to diagnose the size of the effect achieved after the training process, Cohen's d and the biserial correlation (rxy) were used. The analysis was used, taking as reference the values of p < 0.05 as statistically significant differences.
All values of asymmetry and kurtosis were in the range of ± 1.95, following the premises established by Ref [80] for a normal distribution. The Student's t-test statistic was

All values of asymmetry and kurtosis were in the range of ± 1.95, following the premises established by Ref [80] for a normal distribution. The Student's t-test statistic was measured by the degree of independence of the results obtained, although from two different perspectives. Independent samples were analyzed, that is, a comparison was made between the traditional teaching method and the groups that used active methodologies and makerspaces, both in the pre-test and in the post-test.

Results
The results obtained after applying the different statistical methods are presented below. In general and descriptively, in Table 1, the results of the control and experimental groups can be observed in the pre-test and post-test questionnaire.
In relation to the results of the pre-test data, both the experimental group and the control group presented similar values in each of the STEAM dimensions. For the control group, the dimension with the highest score with a mean of 2.30 was Positive Communication (POST_COM), and the one with the lowest score with a mean of 2.21 was Transdisciplinary Thinking (TRANS_THINK). For the experimental group in the pre-test, the dimension with the highest value was also POST_COM but with a mean greater than 2.35, in reference to the control group. In contrast, the least valued dimension with a mean of 2.18 was Authentic Approach and Tasks (AA_TASK). In the analysis of the results of the post-test data, higher values were observed in all the study dimensions in the control group. Specifically, the most valued dimension in the experimental group taking the post-test was, again, POST_COM, with a mean of 2.63, that is, 0.33 points more than in the pre-test results. In contrast, the lowest valued dimension in the control group was Peer Interaction (PEER_INT), with a mean of 2.37. In turn, in the experimental group, the dimension with the highest mean value in the post-test results was also POST_COM, with a mean of 2.26, that is, 0.09 points less in relation to the pre-test results. On the other hand, the mean with the lowest score was the dimension PEER_INT 1.77, that is, 0.44 points less in relation to the pre-test results.
Considering the standard deviation, it was well below one point in all the study dimensions, both in the pre-test and post-test measures. In this case, it can be considered that there was no response dispersion. Students tended to agree on their answer. All asymmetry and kurtosis values were between +/−1.96, thus being the premises set by Ref [80] for a normal distribution. Finally, the kurtosis values showed that the response trend was mainly platykurtic.
The comparison of means of the different study dimensions shows, graphically, in Figure 5, the following: Eur. J. Investig. Health Psychol. Educ. 2022, 12, x FOR PEER REVIEW 9 test measures. On the other hand, the least valued dimension in each of the measures taken in each of the groups varies. The great difference in the mean of the measurements of the experimental group stands out in the post-test results of the PEER_INT and TRANS_THINK dimensions, in relation to the rest of the dimensions and measurements. In these two cases, they usually have a difference of at least 0.34 points with respect to the rest of the dimensions. Both dimensions, in the pre-test results, have a higher value in the experimental group. The degree of independence of the results obtained was introduced with the Student's t-statistic, although from two different perspectives. On the one hand, independent samples were analyzed, that is, a comparison was made between the control groups and the experimental groups, both in the pre-test and post-test tests. The data visible in Table  2 show that the comparison between the control group and the experimental group is significant in the post-test measurement of the PEER_INT, POST_COM and TRANS_THINK dimensions. This shows significant differences in favor of the control group. In the rest of the dimensions and comparisons, no significant differences are ob-  The great difference in the mean of the measurements of the experimental group stands out in the post-test results of the PEER_INT and TRANS_THINK dimensions, in relation to the rest of the dimensions and measurements.

This shows significant differences in favor of the control group. In the rest of the dimensions and comparisons, no significant differences are observed. In the previously indicated dimensions, in which a significant relationship is observed, the biserial correlation is medium. The effect size is very low in all dimensions, both in those with a significant relationship and in those without a significant relationship. On the other hand, the related samples were analyzed, that is, between the pre-test and post-test tests of the control and experimental groups (Table 3). In the experimental group, two dimensions are observed in which there are significant differences. This is the case for the PEER_INT and TRANS_THINK dimensions. In this case, the pre-test measures are superior to the post-test measures. That is, the evaluation of the students drops significantly in the experimental group. In the control group, there are significant differences in the pre-test and post-test measures in the COM_POS dimension. In this case, the post-test scores are higher than those of the pre-test. In the rest of the dimensions and comparisons, no significant differences are observed.

Discussion
After the suspension of classes in educational centers caused by the confinement of COVID-19, Spanish schools had to adapt spaces and resources to the demands and measures of political institutions in matters of education and health, as indicated by the government of Spain [69]. Educational centers have coexisted with technology, as Ref [1] points out, although this fact has presented a problem for schools in their educational projects in general and classroom methodologies in particular. In schools that include the STEAM methodology and have makerspaces and Classrooms of the Future in their teaching-learning process, it has meant a "before" and "after" the pandemic. In this sense, the axis of this STEAM-EDU study also suffered an impact on its disciplines for the students that we proceed to discuss.

In Relation to the First Study Objective. To Compare How Working with Steam-Edu Influences Each of the Dimensions of the Study before the Pandemic Using Different Methodologies
The data from the pre-test study showed different results in the control and experimental groups. We agree with Refs [21][22][23]33,34,40,41] that TRANS_THINK had a better statistical evaluation in this study among the students of the experimental group that used STEAM and computational thinking as a discipline that allows them to solve and approach a problem, not necessarily math, and work cooperatively in person. This fact confirms that discussing how to approach a task, activity or problem and co-creating projects across multiple disciplines contribute to the development of transversal and critical thinking. In addition, the lines of research of Refs [4,5,9,29,46,58,59] support the results of the experimental group that developed the creativity of students by exchanging opinions, ideas and carrying out co-creation of projects. It also allows one to check what other colleagues do when presenting their projects from any area of the curriculum, such as the "present area" within a Classroom of the Future, all from motivating work spaces for students.
Another discipline with the highest score for both groups, experimental and control, was POST_COM. However, there was a higher assessment in the experimental group over the control group. Therefore, these results support previous studies [2,33,36,66] where STEAM-EDU facilitates communication in schools, respecting the ideas of others, listening and respecting turn taking. In addition, these skills allow socially appropriate behavior among the peers of the students in their lives and develop oral expression and comprehension, contributing to linguistic competence, supporting the lines with the research of Refs [24,25] from the makerspaces and Classroom of the Future, as also pointed out by previous studies by Refs [58,59].
On the contrary, the discipline with the lowest value within the experimental group, although above the average, was Approaches and Tasks (AA_TASK), also with a lower value compared to the control group, which presented a higher value. These data are not in line with the results of previous studies by Refs [11,38,60]. Before the pandemic, the experimental group did not consider it relevant to use technological tools in collaboration to tackle tasks, reflective learning (STREAM), negotiate relevant methods or materials to solve a problem. Learning through online educational platforms individually or in groups was not considered necessary by the students. Therefore, the results of this discipline agree with the study by Ref [3], in that a change in methodological approaches was not necessary to achieve STEAM skills, in this discipline specifically and before the pandemic.
The data for the Peer Interaction (PEER_INT) and Multiple Options Consultation (MUL_PATHS) dimensions are above the mean of the study scale in both groups and with similar statistical data. These results support the lines of research of Refs [31,[53][54][55] that highlight the lack of innovation in schools to develop disciplines, such as supervising and distributing tasks with their peers, negotiating roles, checking processes, asking appropriate questions to solve problems or verify research sources through STEAM methodologies in makerspaces and Classrooms of the Future, as established by previous studies by Refs [55,66].
The discussion of this objective responds positively with hypothesis H 1 , despite being a STEAM-EDU field with little research on methodologies and teaching resources, as pointed out [19,20,51]. The experimental group that developed the STEAM disciplines through computational thinking in makerspaces and Classroom of the Future had a significantly better assessment by the experimental group in two disciplines, TRANS_THINK and POST_COM. In addition, in two other disciplines, PEER_INT and MUL_PATHS, although the assessment was very similar, they were data that we can consider positive. By using a STEAM methodology, these disciplines that require training among teachers and are in the process of being implemented in the official curricula of primary education in Spain, as also pointed out [2,56,57], at least do not have a worse evaluation between students in the experimental group versus the control group.

In Relation to the Second Objective of the Study. To Know the Impact That the COVID-19 Pandemic Has Had on the STEAM Disciplines
Before the pandemic, the STEAM-EDU methodology, through computational thinking from collaborative and creative learning spaces, had a worse rating in the AA_TASK dimension. However, it is noteworthy that the only dimension that experienced a significantly better assessment in the experimental group in the post-test with reference to the pre-test was AA_TASK. In line with the study of Ref [11], the pandemic, the confinement, and later, the restrictions in the classroom made the students of the experimental group of this research better value the need to work with online digital platforms.
In line with Ref [67] and in accordance with the results of the experimental group of this study, the POST_COM and TRANS_THINK disciplines improved in the Classroom of the Future. However, unlike the first objective that we discussed, the data confirm that the pandemic, together with the preventive measures in Spanish schools, had an impact on the experimental group that developed active methodologies, as supported by the study by Ref [68], especially in PEER_INT, POST_COM and TRANS_THINK in a negative way, although above the average evaluation. That is, working in the classroom as a group or exchanging ideas among peers through fields of computational thinking, such as robotics, programing or artificial intelligence, as supported by studies by Refs [41][42][43]51], are considered beneficial for transdisciplinary learning. However, according to the results of this study, the students of the experimental group valued these disciplines less when working individually and without being able to share resources or being able to move to creative spaces.
The results of this research linked to the PEER_INT dimension and its variables, in relation to previous studies by Refs [21,22], which support carrying out face-to-face collaborative activities that require direct interaction between students, are not in line with the results of this study during the pandemic in the experimental group that developed STEAM-EDU methodologies due to the impact of restrictions in the classroom for health reasons. In the same way, the studies by Refs [6,67] that support the use of creative spaces of makerspaces and the Classroom of the Future to investigate, interact, explore, develop, create and present were less valued by the experimental group in the post-test data.
The discussion of this objective nullifies hypothesis H 2 , that is, the STEAM-EDU disciplines during the pandemic are better valued in the experimental group compared to the control group. Although, in reality, the post-test results are evidently lower in the experimental group than in the control, even in reference to the experimental group itself in the pre-test. We can consider these results in favor of STEAM-EDU when classes return to full normality and without restrictions. This is due to the fact that the STEAM-EDU methodology in spaces such as makerspaces and Aula del Futuro generates motivation, as indicated by previous studies [27,28], and the restrictions imposed by the pandemic have interrupted a way of working that the experimental group considered positive and effective.
In reference to the main objective of the study, "Evaluate the STEAM dimensions in sixth grade of primary education in times of pandemic", the post-test results of the experimental group support the lines of research of Refs [19,20] in relation to the fact that there is little research on STEAM-EDU teaching methodologies and resources among teachers, who encountered an added difficulty during the pandemic, that is, the restrictions implemented in educational centers by the government of Spain [69]. Finally, in the experimental group, the possibility of creating, researching, interacting, exploring, developing and presenting, which are areas of the Classroom of the Future, and these actions are associated with the pyramid of Bloom's taxonomy, are enriching cognitive processes that are achieved through computational thinking, following the lines of research in Refs [40,43,44]. In this study, the pre-test data show that they are viable but not as a result of the pandemic.

Conclusions
The conclusions of this research are that the methodologies based on computational thinking within makerspaces and Classroom of the Future before the pandemic were developing a positive impact on the STEAM disciplines, except in the AA_TASK dimension, where the use of digital platforms to work in the classroom was still not so relevant at that time. Therefore, the motivation generated by students in this digital society to work with technological tools and resources in the classroom is an unquestionable fact that has repercussions on STEAM disciplines, always from a didactic and pedagogical approach.
Another conclusion of this study is that the restrictions on the use of common spaces and the exchange of technological resources due to the pandemic have been detrimental to educational centers that develop computational thinking in creative spaces, harming STEAM disciplines because this methodology implies "know-how" and a bidirectional education, where the teacher is the guide and the students the protagonists. However, we can verify that a drop in the ratio after the pandemic positively influenced the evaluations of the control group in the post-test, not being able to determine what would have happened if the experimental group had worked on active methodologies through computational thinking in makerspaces and Classrooms of the Future in smaller groups without health restrictions.
Among the main limitations of this study is the sample selected only for students in the sixth year of primary education and in a specific sociodemographic area in Spain. This study can be transposed to other educational levels and stages and related to other variables, such as gender, sociodemographic characteristics or the use of electronic devices in homes and schools.
As future lines of research, studies can be carried out from September 2022 on the impact that STEAM disciplines will have on Spanish schools. The government of Spain will implement the School Code Plan 4.0 and will involve an investment of EUR 356 million over the next two years, officially including computational thinking and robotics in its curriculum in the stages of early childhood education, primary education and secondary education in centers supported by public funds. These fields are considered by the Spanish government as the new language of the present and future in schools.
The findings of this study are of interest to researchers and professionals in the educational world, both in formal and informal education. It is important to be aware that technological and digital tools and devices are prominent in many daily tasks, including in the world of work. Policies and centers must include training activities related to computational thinking from makerspaces and Classrooms of the Future from an early age to promote STEAM disciplines. If the world of work needs professions that require digital and technological skills, schools are the first link to achieve it. Funding: This research did not receive external funding.
