A Review of Gesture and Vocabulary Learning in a Second Language 1. Overview Nowadays, the pivotal role of Community of Practice in language learning have been advocated by many researches. (e.g. Haneda 1997; Martin-Beltrán, Guzman, and Kidwell 2019; Montante 2019; Murray and Fujishima 2013; Peercy, Martin-Beltran, and Daniel 2013) Moreover, studies on CoPs in language learning contexts have revealed that CoPs play a great role not only for language learning but also for intercultural exchanges. This study investigates the linguistic and sociocultural benefits that multilingual individuals gain through participation in a Community of Practice (CoP) in Indonesia, a typically multilingual country. Using an ethnographic approach and guided by Wenger’s CoP theory, data are collected through participant observations and semistructured interviews. Eight key themes emerge from the analysis: the empowerment of social media, innovative language activities, learning support, personal learning freedom, intercultural exchange, sharing online learning platforms, free language learning, and social networking. The findings suggest that language learners can adapt to the methods used by multilingual individuals in this community to enhance their foreign language skills. It is obvious that many impressive points should be mentioned. First, the current study addresses a research gap in the research field of CoP in language teaching and learning. Although many studies have explored CoPs in language learning, research specifically focusing on the affordances of multilingual learning communities is sparse. To bridge this gap, this study examines how a multilingual practice community (MPC) in Indonesia facilitates learning opportunities across multiple languages. Considering the invaluable significance of affordance in language learning, the implications of this study are significant, which suggest potential benefits for CoPs by providing language teachers with more affordances to aid their learning. Second, the literature review progresses logically, starting from the basic conception of CoP and the theoretical framework of the study, namely Wenger’s CoP theory, combining this useful informal learning tool with various studies about informal language learning, and introducing the specific studies on language learning through CoPs. In this way, readers can see the important role of CoPs and have an urge to see whether it will have several impacts on multilingual participants in this study. Third, the writing format of this study is both rigorous and logically structured, which may be helpful in our thesis writing. Just as we have said before, the theoretical framework used in this study is Wenger’s CoP theory. In the literature review section, the content of this theory is clearly demonstrated so that readers can have a quick grasp of this theory. What should be mentioned is that in discussion section, the eight affordances in the results section are also discussed according to Wenger’s CoP theory. That is to say, different affordances can be included in different stages. This reminds me that in our own thesis discussion writing, we could not do it as our please. Instead, we have to follow the logical unfolding of the research question and closely relate it to previous research as well as using an authoritative framework to analyze the findings. 2. Reviews for Sections 2.1 Abstract The research report’s abstract is succinct and well-structured. It provides a clear background on the research topic, highlighting the prevailing focus of previous studies and establishing the link between CoP and language learning in multilingual contexts. Moreover, the abstract also outlines the study’s innovation by delving into how a multilingual practice community (MPC) in Indonesia facilitates learning opportunities across multiple languages. It adeptly covers essential components, including the study’s purpose, significance, methodology, and conclusions, serving as an instructive model for our writing. 2.2 Literature Review and Theoretical Framework Based on the concept and goals of community of practice, the authors review previous studies on CoP in language learning contexts. Gumperz (1982)’s notion of a speech community, where language norms are shared among a group, aligns with Milroy and Gordon (2003) ’s idea of CoPs as social networks where language and social meaning are coconstructed. And then the authors have found that the previous studies show that community of practice is not only for language learning, but also for intercultural communication with significant help. Therefore, in the literature review section, the authors first give a brief introduction to the basic concept of CoP, which can be used as a learning tool to learn the norms and language of a particular community. Then the theoretical framework utilized in this paper is the three-stage theory of community of practice proposed by Wenger. In the first stage of Mutual Engagement, new and senior members of the community work together to establish a sense of membership as a foundation for the realization of the group task, and in the second stage of Enterprise, members actually cooperate with each other and participate in the completion of the task in order to learn the language and maintain their identities. The third stage, Negotiable Resources, entails members sharing shared resources with each other and negotiating to accomplish the community’s tasks. Considering that learning styles such as CoP belong to informal education, the contrast between it and formal education is that it pays more attention to the interests and needs of the participants or students, and therefore the results of the previous studies have shown that language learning can be effectively promoted in the context of informal education, so more and more researches have started to pay attention to the language learning through CoP. Most of them focus on the what, why and how aspects, including elaborating and validating the concept of community of practice, applying the community of practice to different language learning contexts, and exploring members’ views and evaluations of the community of practice, as well as its effects on the learning of language skills. Despite these studies, the authors believe that there is a research gap in that few studies have examined Affordance, or availability, or provision in multilingual learning in the context of communities of practice. In language learning, this affordance arises from learners’ participation and use, and opportunities for learning arise as a result of participation and use. At the same time, the effectiveness of language learning communities may vary in different contexts, so in order to fill this gap, this study aims to investigate the affordance of opportunities to facilitate multilingual learning in a multilingual community of practice in Indonesia. It is developed from the perspective of the participants to see what is available to them in this community for their language learning. 2.3 The Present Study and Its Method The research conducted within the multilingual community in Indonesia revealed a vibrant and dynamic learning environment, characterized by rich linguistic diversity and a shared dedication to language learning. The community, which the authors refer to as the Multilingual Practice Community (MPC), provided a unique social learning space where members could engage with multiple foreign languages and cultures. The MPC welcomed language enthusiasts of all backgrounds and ages, from academic students to professionals in various fields. To join, individuals can follow the community’s social media channels, such as Facebook, Instagram, or Twitter, where details like meeting schedules, language-related events, learning resources, and updates are regularly shared. Notably, this community caters to less commonly studied foreign languages in Indonesia, such as Hindi, Russian, Turkish, Korean, Italian, and Spanish. Data are collected through participant observation and semistructured interviews, with the first author acting as a participant-observer, who informed the MPC members about the study, objectives, and the information that follows the research. So, in addition to the first author as a participant in the study, there are eleven other participants in this study, and they consist of two panelists who act as facilitators in the different language groups, and nine other members who volunteer to learn one or more languages to a greater or lesser extent. The nine of them then participate in subgroups of a total of ten different languages. Some of them may participate in only one group, while others may then participate in five or six groups. Information on how this community can help them to improve their foreign language skills are collected, and also several semi-structured interviews will be conducted to validate the data the authors obtained from the observations. Thematic analysis, informed by CoP perspectives, is employed to analyze the interview data. After reading many papers on qualitative research during this semester, I also find that classroom observation as well as interview method is one of the most common research methods. However, when using these methods, we also need to analyze the data systematically based on the theoretical framework, just like the author of the paper. 2.4 Results and Conclusion As for the findings, eight themes have emerged from the study: social media empowerment, innovative language engagement activities, learning support, personal learning freedom, intercultural sharing, sharing online learning platforms, free language learning opportunities, and social networking. The first is the empowering social media. The members unanimously recognize the usefulness of social media for communication in this community, where they could learn languages together by asking questions, answering questions, recounting original learning experiences, and sharing learning data. Secondly, there are innovative language engagement activities in this community. Participants in the community choose their own representative locations for language learning, and then they are free to choose to learn more than one foreign language, so there is a high degree of autonomy among the members. Thirdly, there is learning support, since there are two of the participants act as moderators, who can guide the discussion of each topic and provide opportunities for other participants to practice the foreign language. The fourth one is that the participants are free to choose their own strategies and styles of learning foreign languages, and in the relaxed and enjoyable atmosphere of the community, they are able to use it as a way to learn the language and make new friends without the pressure of grades, assignments, and exams. Fifthly, there is intercultural sharing, because when some of the participants live abroad and return home, only to find that they do not have a partner to practice the language they learned abroad. But in this community, they can practice with participants from similar backgrounds, and learn the language through cultural encounters. Sixth, participants also share online learning platforms, including their learning resources and information about online learning. Seventh, in this community they learn the language for free compared to formal education. Finally, the participants feel that in this community they have created a social network, have been able to find people with the same language interests, and have developed their social network while improving their language skills. These themes highlight the various affordances that facilitate multiple language learning opportunities within the MPC. The findings suggest that the MPC provides a supportive environment for language enthusiasts to practice and improve their language skills in a nonclassroom setting, promoting both linguistic and intercultural competencies. 2.5 Discussion and Implication Just as what we have mentioned in the overview part, the authors demonstrated the discussion part according to Wenger’s CoP theory to see whether the participants have successfully built a multilingual CoPs. Based on the eight affordances and several activities they have found during the research, the authors classified them into the three stages of Wenger’s CoP theory. For instance, innovative activities belong to the mutual engagement, which helps create a community as a place where people who have the same language interest can gather together and contribute to active interaction. And in joint enterprise, participants set up as the mission they need to achieve in response to their situation through practicing language in the multilingual context that enjoys the free atmosphere for them to learn the language freely and easily. And of course, this research also shed lights on the future researches in the following aspects. For language teachers who are delighted to establish a CoP in their environments, the findings show various management strategies educators might consider to encourage the enactment of CoP for language learners. Further, for potential members of the community, other than culture and language learning, members could also see opportunities for social networking. Also, future research should address the agency and identity of those who are involved in the CoPsbased language learning activities in relation to the sustainability of that community. 3. Critiques of the Research To conclude, this research provides valuable insights into the affordances of a multilingual practice community (MPC) in Indonesia. The use of Wenger’s CoP theory as a framework is appropriate, as it highlights the social processes involved in language learning within a community. The ethnographic approach, combining participant observation and semi-structured interviews, allows for an in-depth understanding of the community’s practices and the perceived benefits of multilingual engagement. One significant advantage of this methodology is its ability to capture the dynamic and interactive nature of the MPC. By being a participant-observer, the first author could gain a deeper understanding of the community’s practices and the nuances of member interactions. The thematic analysis also provides a comprehensive overview of the various affordances that facilitate language learning within the MPC. However, there are also some limitations to the study. The reliance on self-reported data from interviews may introduce bias, as participants might present their experiences in a more favorable light. Additionally, the study’s focus on a single community in Indonesia may limit the generalizability of the findings to other contexts. Therefore, future research could benefit from a comparative analysis of multiple multilingual communities across different cultural settings to provide a broader perspective on the affordances of multilingual learning. In terms of reliability and validity, the study employs robust data collection and analysis methods. The use of participant observation and semi-structured interviews allows for triangulation of data, enhancing the credibility of the findings. And the thematic analysis, informed by CoP perspectives, provides a systematic approach to identifying key themes and patterns in the data. Overall, the research contributes to the understanding of how multilingual communities facilitate language learning through social and interactive processes. It highlights the importance of informal learning settings and the role of social media, intercultural exchange, and personal learning freedom in promoting multilingualism. The findings have practical implications for language enthusiasts and educators, suggesting that the practices of the MPC can be adapted to enhance language learning in other contexts.
