The Potential of TikTok’s Key Features as a Pedagogical Strategy for ESL Classrooms

: The predominance of the use of the English language on social media entails its potential usefulness in regard to ESL learning. Amongst all social media platforms, none can boast the ubiquity of TikTok. This application has been, and continues to be, one of the largest and most inﬂuential social media platforms, as well as a massive success across a range of ﬁelds with the most active users in the world. In the ﬁeld of education, it has the potential to enhance educational pedagogies. Although TikTok has various features aligned to language learning, TikTok’s application within the education ﬁeld is still largely unexplored. This scoping review aims to identify the key features of TikTok that can be used to enhance pedagogical strategies in sustaining the teaching of language skills in ESL classrooms. Although studies have been conducted on this subject, they have often lacked clarity and also lacked the possibility of synthesis in regard to the contribution of this platform to language education. Thus, this scoping review is conducted in order to identify the useful TikTok elements that strengthened pedagogical strategies in ESL classrooms. A total of 60 publications with publication dates spanning from 2018 to 2021 were chosen from searches on the EBSCOhost, Google Scholar, and ERIC databases in order to illustrate the current state. The outcome of using the identiﬁed features of TikTok and key pedagogical TikTok strategies for the purposes of ESL learning were the two themes used to synthesize the data. Findings indicated that video-related features and the duet challenge feature in TikTok have potential in promoting engaging and meaningful learning, in the context of a virtual environment. This potential has enabled the use of major pedagogical strategies, such as digital assignment; active learning; collaborative and team-based learning; experiential learning; and incidental and constructive learning. Although using TikTok is beneﬁcial for the purposes of language learning, the ﬁndings of this study also revealed several limitations associated with the platform, such as users’ behavior, poor infrastructure, and an absence of online discussion forums. This review contains suggestions for the purposes of assisting teachers in terms of maximizing their use of TikTok, via overcoming the challenges that were highlighted in previous studies.


Introduction
The digitalization of technology is a critical component of Industry 4.0.Parallel to this, all digitalization examines the language being used.Not surprisingly, English predominates among the languages used in digital communications worldwide.
The most vibrant development that is interconnected with the teaching and learning of English is social media.This is due to the fact that most students are actively engaged in social media, thereby allowing them to be susceptible to the interconnection of technology and the learning of English as a second language.
Social media platforms, particularly TikTok, have revolutionized how people socialize and communicate.The app is now the most downloaded app on the entire globe with over 1 billion downloads.TikTok is also transforming the educational environment in the education sector, including in the case of online learning [1].Applying social-networking learning is the new frontier in the context of improving learning social media such as TikTok also aids in improving students' self-efficacy toward academic improvements [2].As one of the most popular social media platforms worldwide, TikTok is also present in the education sector.Pedagogical strategies denote abstract teaching techniques that influence instructional design models, such as collaborative, reflective, integrative, constructivist, and inquiry-based learning [3].This is consistent with the vision of Generation Z, who use social media to communicate, discuss ideas, and obtain-as well as to provide-educational information.TikTok has thus been examined for its pedagogical potential, due to this same influence and/or impact on teaching and learning.
In light of COVID-19 s limitations on group or paired activities, this review takes into consideration the issue of decreased and inhibited language practices in past studies.An alternative method of language practice, particularly in regard to practice using social media, is required for students as they spend more time at home.Students rarely interact with their friends during school closure.Their English lessons were reduced to written exercises due to the fact that the hardware and software limitations at the time made online lessons able to barely support group speaking exercises.Thus, there is a gap that this review seeks to fill, namely, to identify and synthesize the enabling features of TikTok in regard to promoting pedagogical strategies, as well as to identify the unique ability of TikTok to do just that.

Background of the Study
Technology advancement has gently forced most countries, even those that were previously hesitant to include foreign languages (such as in China, Russia, and Japan), into accepting English as the language of technological progress.This use of English is known as Digital English [4].Furthermore, the impact of technology, in many fields, has brought positive impact to most, if not all, countries.In regard to education, technology has led to many positive changes and development in the teaching and learning process as well.Moreover, there is also an intertwined relationship between technological development and English language development in respect to the teaching and learning process.
Social media has a pull factor that can be exploited in order to attract students' attention and provide positive reinforcement.A theory that is relevant to TikTok is the 'uses and gratification theory' (which is commonly also known as the U&G theory).The uses and gratification theory is an analytic tool that helps to explain the use of media in the context of gratifying specific needs and wants.For purposes of this study, there is a need for learners to have learned to speak using a social media app, such as TikTok.This theory helps with understanding the user as an active element, rather than as a passive element (which is the case in other theories).U&G theory is utilized in order to focus on the user as an active user who has control over their media consumption.It is also used to investigate the satisfaction of the users when they use social media in order to find information.The fact that TikTok has been downloaded over a billion times entails the fact that it has certainly gratified users and, by extension, theoretically increases the chances of learning taking place [5].
Undeniably, the power of social media to garner attention among the masses is immense.Social media presence is not merely infiltrating individuals, but is also being actively applied in organizations in order to increase presence and to thus improve the quality of information dispersion to the public [6].
When narrowing the scope to the education sector, social media can be a free-for-all platform for teachers to disseminate information and champion education beyond more traditional classroom concepts.This is also reiterated by [7], whereby they stated that learning writing through social media presents opportunities for students to write and expose their writing to the outside world.This provides meaning to their writing process, which helps them to develop their writing skills.Social media platforms such as Facebook provide a platform for writing to occur, while other social media such as Twitter emphasize summarizing what you have to say within a word limit.Therefore, these social media apps can provide a two-thronged approach for English teachers, be it in regard to the open writing that is developed through Facebook or the learning of how to summarize while using Twitter.Thus, students subconsciously improve their writing skills and benefit from the sharing that takes place on social media.This is due to the fact that students are able to read other materials outside the classroom, which also relate to the world as well.
There are many social media platforms that are open access and thus free to use.For this review study, the focus will be on the platform TikTok.The use of TikTok, particularly in the context of using short educational videos, helps learners to learn media and improve their speaking, English pronunciation, and English writing skills.Therefore, in this regard, TikTok has become useful tool in regard to teaching English to second language learners as a pedagogical strategy.The context of English as a second language (ESL) is where students who are not native English speakers are primarily taught in English by focusing on language skills more than content [8].Furthermore, the technological upper hand also improves students' quality of life in regard to engaging better with friends and people around the world [9].TikTok has several features of note for this purpose, such as shared audio, which allow users to use the audio to listen and mimic voices.It also possesses the duet feature, whereby a user can stitch their video with someone else in order to create new content that looks similar to two individuals conversing.All these features and possibilities render it easy for students to be involved in learning English in a manner that entails that the ESL students rely on it positively.This also promotes a blended learning process, which improves the teaching and learning process of English as a second language, such that students will be fully immersed in their experiences.The TikTok app can thus aid students in improving their reading and speaking skills when it is used correctly in the context of an ESL classroom.

Materials and Methods
A scoping review framework was adopted in this study.This was conducted in order to perform a review of the research where TikTok was used as a pedagogical strategy among ESL learners [10].A scoping review method is preferred as this form of review enables a mapping out of the selected important, relevant literature that is related to the focus area discussed in this review.Furthermore, it provides necessary guidance and clarity on broad issues, such as this very same issue that focuses on social media usage in English classrooms.All five steps of the framework were followed.These steps comprise the following: (1) research question identification; (2) identification of relevant studies; (3) study selection; (4) data charting; and (5) report summarizing and reporting.

Scoping Review Research Questions
Review question: What features of TikTok can be used as a pedagogical strategy in ESL classrooms?
In the scoping review framework developed for this study, four objectives for conducting a scoping review were identified [11].One of these aims was to establish the extent, nature, and range of existing research activity.Such an objective is appropriate in mapping fields in cases where visualizing an available range of materials is challenging.Using TikTok as a pedagogical strategy is one such field.Therefore, such an objective was adopted for this paper.The main goal, in this study, was to determine how much research has been conducted on the role of TikTok in the context of teaching ESL students.Therefore, this study adopted broad research questions that would enable the achievement of the aforementioned aim.The preliminary research question of the study was to identify "What are the features of TikTok that can be used as a pedagogical strategy in ESL classrooms?".Identifying this aspect of the research question is critical.Moreover, this informs the search strategy that was used to retrieve the articles [10].TikTok, pedagogical strategies, features, and ESL learners are all also important concepts within this study area.These concepts were thus defined from the outset of the studies; further, the implications of adopting certain positions in their review were also assessed.For instance, the study adopted a broad and generalized approach to defining and discussing these concepts.Adopting such a broad perspective minimized the chances of missing out on relevant articles.The generalized approach allowed the retrieval of an equally wide selection of articles.The article may not have mentioned the concept directly, but could have addressed related issues.In this paper, the recommendation of [11] in the context of generating wide coverage was followed.

Identification of Relevant Studies
As mentioned, scoping reviews mainly aim to establish the extent, nature, and range of previous research; as such, it is required to be as wide and as comprehensive as possible.Therefore, the methods used to identify articles should support the comprehensive goal of the study.This includes searching for relevant articles from key databases, namely EBSCOhost, Google Scholar, and ERIC databases.EBSCOhost was selected due to the fact that it is one of the largest electronic databases for credible, peer-reviewed scholarly articles [10].The researchers were certain that it would be possible to retrieve a relevant and wide array of articles from this website.ERIC also offers a wide variety of academic articles.The authors used it in order to diversify the selection of sources and consequently increase the breadth of the retrieved articles.Finally, Google Scholar was selected due to its advanced search algorithms, ability to connect researchers to other electronic databases, and the fact that it presents only credible academic sources.
Only articles published between 2018 and 2022 were included.The decision to limit the time frame of published articles was necessitated by, first and foremost, the time and budget constraints the researchers faced.The time range is also critical in enhancing the practicability of a scoping literature review.Recent articles are arguably more effective in highlighting the scope of research existing in a given field.
The aim of this study also informed the search terms used in the study.The research team used broad search terms in order to increase the breadth of the findings, instead of using Boolean search operators that could narrow down the findings to specific keywords.The broad search terms used in this study are mostly in the form of search questions and phrases.The precise search phrases used in this scoping review included the following: 1. How to use TikTok as a pedagogical strategy among ESL learners; 2. Using TikTok to learn a second language; 3. Features of TikTok as a pedagogical strategy; 4. TikTok, Pedagogical Strategy, and ESL learners.

Charting the Data
After the selection process, each article was classified according to its main issues and what was based on its research questions. Figure 1 shows a PRISMA 2009 flow diagram that details the process that was undertaken when identifying the relevant studies involved in this review.

Results
A total of 60 articles were retrieved to be used for the scoping review that was intended for this study.The articles were categorized based on the theme or key issues they addressed.These issues were often based on the ESL learners' perceptions in the context of the outcomes of using TikTok, as well as the key pedagogical features of TikTok that led to potential pedagogical strategies being used on TikTok.Table 1 contains a summary of information retrieved from these selected articles.The summary and categorization of these studies were conducted in accordance with the content of the author, title, location, sample, research design, type of instruments, findings, and features.The studies were conducted in various areas of the world.However, the majority of these articles were from Malaysia (12), Indonesia (6), China (7), and India (4).The study also used various research designs, namely, qualitative, quantitative, and mixed methods.

The app provides necessary social support in order to gather those who are interested in improving their language skills.Their English skills are then channeled through making comments in order to better apply the language.

Discussion
Based on the abovementioned articles, the two main themes that were able to be synthesized from these past studies were the outcomes of using TikTok pedagogical key features and the pedagogical strategies of TikTok that are relevant to ESL learning.
The pedagogical strategies elicited were found in 29 of the papers on digital learning and assignment; 8 papers on active learning; the 7 papers on collaborative and team-based learning; the 4 papers on experiential learning; the 3 papers on incidental learning; and the 2 papers on constructive learning.This shows that there is a wide range of strategies that TikTok has promoted and can make possible.The results also highlight the impact of social media, whereby focusing on TikTok toward its potential in the teaching and learning process for pupils-as it encompasses an array of strategies that can be applied by educators and teachers-in order to enhance the speaking skills of learners, specifically, as well as the proficiency of learning English, in general.
There are various key features-which were obtained following the review of the selected articles-that are useful to discuss in this section.The most prominent key features include the inclusion of technology in the learning process.The impact of technology is undeniable as the factor that pulls users in to improve their speaking skills.This is because it allows imitation and modelling, which provide real-time examples with various content that are based on different situations.This is also highlighted by [27], who advised that project-based learning can be conducted easily when using TikTok, due to the fact that it serves the right purpose of assessment for the purposes of improving English speaking.It is likened to a bank of content, ready to be used at any time by the teacher.Hence, it reduces the burden of the teacher to prepare materials, who are then able to use readymade materials that are already contextualized within a real-world scenario.This will have a positive impact on pupils' proficiency as they are able to practice the language when it is based on real-world situations that are available through TikTok's duet challenge concept [55].This is in line with the most frequent pedagogical strategy that is analyzed in all of these papers: the cases of digital learning and digital assignment.Therefore, there is a need to acknowledge the importance of utilizing the correct digital learning strategies.Furthermore, this is important due to the fact that they are a vital component in planning present and future classroom strategies in order to further develop teaching pedagogical and methodological skills [56].
Another study explored the features and outcomes of using TikTok, especially in the case of the ESL learning environment [36].ESL students who did not understand complex vocabulary found it easy to understand English using TikTok, which is a significant outcome.This includes the pronunciation of difficult words and the manner of speaking, such as tone and intonation.Therefore, when utilizing TikTok's duet challenge feature, other strategies, such as incidental learning and constructive learning, also take place.This fact allows pupils to learn at their own pace, achieve their mastery, and move toward a better understanding of English structures and concepts (which can be difficult to properly learn and understand).Similarly, other studies have confirmed that utilizing TikTok helps learners to improve their communication, speaking, and writing skills, respectively [27].Another outcome linked with TikTok is that ESL learners can learn how to express themselves inside and outside of the classroom setting.This leads to an emphasis toward active learning and experiential learning strategies, which is crucial for gaining experience in order to understand how speaking English occurs outside the classroom context [54].This is further validated by another study in which it was advised that social media use, such as using TikTok (which is actively used for this study), leads to an increased positive perception toward valid academic success, especially when the learner is not a native speaker of the language.Using short videos promotes confidence among learners, thereby significantly impacting academic performance and interaction, or via socialization with others.That said, TikTok has a positive influence on educational development; thus, it is appropriate for online learning and improves communication desires among different students.
The effectiveness of using TikTok in the context of ESL learning has arguably been examined by numerous studies [2,[62][63][64].Based on these studies, students tend to express positive emotions toward English material content, thereby improving their vocabulary as they watch TikTok videos in class.Other learners similarly demonstrate positive attitudes toward using TikTok, which serves as an aid in their classroom.This clearly indicates that TikTok positively or significantly affects how interested ESL students are in their classes.This is also related to the collaborative learning strategy that is a key strategy through the TikTok duet challenge feature.This is because pupils learn and support each other's learning through this feature [40].As such, this leads to a warm, non-hostile, and positive environment for the purposes of better development toward learning English, despite English being their second language.The impact of collaboration, despite not being performed face-to-face, can be seen as a success in regard to preaching the idea that learning can happen anywhere and everywhere, including from one's own home.
TikTok, is focused on providing entertainment, information, and socialization and is thus useful for academic purposes.Due to the result of educators' practice in regard to establishing TikTok and other social media applications-as well as in developing teaching and learning contexts in order to improve ESL learners' language proficiency-the academic element has, thus, become the main factor [5].For instance, language-learning based on TikTok videos is now ranked as the most popular knowledge-sharing type of video during the period of 2019 to 2020; this is even in spite of the fact that this trend has been affected by the COVID-19 pandemic.Substantial studies have examined the effects of using TikTok in order to support language learners and improve their language proficiency and skills [61].This indicates that the effectiveness of utilizing TikTok in the classroom setting is not restricted to borders; instead, it has become a global phenomenon with massive benefits to learners.The purpose of teaching and learning in English, or any other language, is to equip learners with the skills to communicate with it effectively [52].Communication indicates understanding and being understood.It is by using TikTok that learners learn not only diverse sounds, but also improve their speaking and writing skills.
TikTok's presence in the education field, mostly in the English language sphere, has paved the way for the development of M-learning.TikTok assists learners by providing a variety of features, such as broadcasting music videos, short musical clips, special effects, notifications, search box video feeds, settings, likes, comments, duets, reactions, and the editing and sharing of videos, as well as opportunities to make money via this platform.TikTok is used by students due to the fact that the videos are engaging [18].They can watch short videos more quickly and with less effort in order to learn more.Any age group can fully benefit from using this platform.TikTok users can use this app anywhere and anytime.As such, this fact also helps to emphasize the educational strategies used, such as collaborative learning, digital learning, and digital assignment-which goes hand-in-hand with the features exhibited through the TikTok duet challenge feature.These features support the strategies that teachers implement, thus ensuring that the application of using TikTok is in line with the advancement of educational prospects, not merely as a gimmick or trendsetter [65].
TikTok is a fun social media platform, or application, for the purposes of classroom activity where students can become a participant in controlling the pace of classroom activity.The social media app, TikTok, allows users to create and share brief videos; further, it is gaining more and more popularity.TikTok is popular among young people in particular, due to the fact that they can use it to share innovative ideas that they and their friends possess [38].Students can utilize TikTok to create videos that are up to 10 min long.These videos are subsequently posted in a series of posts known as "TikTok moments", which are shared with their friends and followers.Posts made by students will be visible to instructors.The material can be altered by instructors, including the duration of each video.The pupils' competitiveness and enthusiasm in their studies would be sparked by likes and shares.TikTok also offers the option for teachers to provide take-home assignments that students can do after class.The recordings that are made and shared via YouTube, and other social media platforms, can thus be stored and retrieved by the teachers.This could be an opportunity for teachers and parents to work together in order to support students' learning outside of the classroom.In so doing this, promotes incidental learning and experiential learning, thereby allowing pupils to be responsible toward their own learning curve and decide how they would prefer to approach it [2].It must be noted that the theory behind this notion is the theory of social constructivism.This theory entails a focus on the importance of learners to collaborate in order to learn.It also results in the focusing on of other parties, such as parents and teachers, in order to provide necessary support and facilitate the learning process, be it directly or indirectly [5].TikTok is a helpful and successful instrument for the purposes of improving language teaching and learning.However, it necessitates an examination of its effects, which will provide all stakeholders in the education sector with significant information.
The practical implications of this study are enormous.Practicing speaking will no longer be confined to the classroom, monitored by teachers, or only with their own peers.Instead, it will be further developed in order to include practice sessions with native speakers of English beyond the classroom.This would improve the quality of practice that will be received by students.
Yet, another practical implication that must be considered is that understanding the impact of TikTok would provide an input for relevant authorities, such as the Ministry of Education, in order to analyze the impact of TikTok usage for English classes.It would also be a practical suggestion for students to use TikTok, either as a practice tool or an assessment tool.Social media roles can be expanded in the field of education, not merely by providing information through short videos, but also as a practical tool for practice and assessment.However, more studies and research with relevant parties and reviews from other literature studies must be conducted before a conclusive step can be derived.For the time being, these practical implications require more reviews and must be further scrutinized with more literature studies that are based on ESL experiences around the world.

Future Work
In regard to the findings found in this study, future studies may wish to further develop this teaching methodology that uses TikTok for educational purposes, particularly in the case of better English speaking.Future work may include creating a TikTok profile with content and ideas that are relatable to a class textbook's speaking activities with unique hashtags.Thus, students can duet with those videos created by other students aligned with the school curriculum.This could also be a great platform to kickstart a flipped classroom concept in classrooms, whereby they can prepare their speaking materials through those duets before being taught.In addition, this future work could also translate into a content bank of speaking ideas.The idea of unique hashtags would help students to refer to other students' videos in order to learn and obtain certain insights into how speaking can be performed.All this also shows the impact of collaborative learning taking place without the teacher's presence.Therefore, these future works should represent a bigger picture of the topic included in this review study, which is to create an English learning ecosystem with TikTok as its impetus.

Conclusions
Due to its evolving nature, the effects of TikTok as a pedagogical learning tool in language learning have not been fully explored due to the fact that this app is still relatively new in educational settings.The results of this review show that this app is gaining popularity among students worldwide due to its functionality and features.These features allow users to have fun and acquire language skills, whilst also serving as an effective and beneficial pedagogical learning tool for millennials.According to the findings of a number of studies, TikTok's distinctive characteristics not only successfully attract students of all ages, but also improve user engagement and determination.Although the TikTok app has certain challenges due to its infrastructure problems-such as slow internet and malfunc-tioning equipment-these can be fixed by ensuring all students have access to the right tools.As the Fourth Industrial Revolution begins, all parties involved in the educational sector must embrace educational tools such as TikTok in the context of supporting and increasing learning as technology-based learning gradually gains further importance.

Limitations of the Study
In this study, the scope of research available in regard to using TikTok as a pedagogical strategy among ESL learners was reviewed.However, this review suffers from a few limitations.One of the main limitations was that it relied on a relatively dated but classic scoping review procedure, as recommended by [10].This framework was selected due to its simplicity, as well as its clear and straightforward manner of application.However, this was compensated by the use of the new PRISMA-ScR framework search strategy.Time and financial constraints also minimized the of the researchers reviewing more articles.Thus, a paid independent assessor was used in order to further confirm the validity of the included articles.
The synthesis of the past studies implied that limitations in regard to the use of this app may include the restriction, by parents, in using TikTok.As TikTok is a social media tool that has a multifaceted use, its application for education may be overlooked by its primary use-which is for socializing.There may be issues with its acceptance in being used and applied for educational purposes, as many issues such as privacy and monitoring may arise.However, it is important for parents to play an active role in supporting the learning process of their children, which can be achieved (in this context) by monitoring their children while they are on the app.Another limitation of the study is the use of mobile phones and internet access.The successful use of this app is only relevant for students with a mobile phone equipped with a camera and internet access.However, there will be issue regarding accessibility in using the app, such as specific learners' internet speeds and internet access, be it due to hardware issues or software issues.
