Reflective practice (RP) by EFL teachers has been found to have the potential to improve teachers’ pedagogical and professional competencies. This study reports the implementation of a contextualized RP model that integrates the Lesson Study (LS) principles by Indonesian English as a Foreign Language (EFL) teachers. The implementation was conducted at six junior high schools over a course of three months. Data collection methods included three-session classroom observations for each teacher conducted during the RP model implementation, and two sessions of focus group discussion (FGD) after the implementation. The research participants included the six EFL teachers who became the model teachers, as well as several other EFL teachers and six school principals who participated as observers. The results demonstrate teachers’ ability to conduct RP before, during, and after lessons. While they missed some opportunities to conduct reflection-during-lessons, almost all model teachers and teacher observers showed competence in reflecting after the lesson. The teachers realized the importance of conducting reflections to improve their teaching practices and students’ learning. In addition, both model teachers and teacher observers obtained the benefits of getting involved in the RP model implementation, became less nervous, and agreed with the sustainability of the implementation. The findings suggest that, in the future, RP should be well programmed by each school or by broader authorities.

We propose the PROSPER (Project, Sustainability, and Perseverance) Learning Model in English for Computer Science (ECS), a course provided by undergraduate Computer Science programs in Indonesian Higher Education Institutions. PROSPER has eight competencies: (1) System Thinking; (2) Critical Thinking; (3) Envisioning for the Future; (4) Personal Involvement; (5) Interpersonal Relations and Collaboration; (6) Tolerance for Ambiguity and Certainty; (7) Communication and Use of Media; and (8) Strategic Action. The syntax refers to Project-Based Learning and has eight stages: (1) choosing the theme of the project; (2) open-class discussion on the correlation between the topic and sustainability; (3) meeting the experts; (4) structuring the project by considering its contribution to sustainability; (5) executing the project in a sustainable way; (6) presenting the project; (7) evaluating the project; and (8) publishing the project. PROSPER model highlights the concept of sustainability and increases awareness, which has real-world relevance on a global scale. The urgency of incorporating sustainability into ECS is intimately tied to student perseverance, which is anticipated to educate them to be change agents for a better world in the present and future.

English lecturers play a vital role in making their students to communicate well in English. They should be able with new and innovative teaching skill and strategis in the classroom to enhance students skill significantly. This research is motivated by the importance of having good English speaking skills, especially for English teachers. The traditional learning methods has been less successful in improving students’ speaking skill. Therefore, one of the solutions offered is to use the Techno Driven Task (Zig Zag Task) in teaching speaking skill for students. This study aims to determine the speaking skills of English students at Pasir Pengaraian University by using computer-aided Techno Driven Task (Zig Zag Task). The research designs is descriptive quantitative research. The participants of this research was the fourth semester students of English Study Program in University of Pasir Pengaraian. The number of samples of this research was 19 students. In collecting the data, the researcher took from students’ presentation when they were using zig zag task. The results showed that the level of students’ speaking skills was at a reasonable to very good level and only a few students had poor skills.

Introduction: Critical thinking skills are core competencies of the 21st century for individuals to solve complex problems, make data-based decisions, and adapt to rapid social, technological, and environmental changes. This condition indicates the need for innovative learning models to encourage active student involvement and develop critical thinking in a meaningful collaborative context. This study aims to evaluate the validity and practicality of the Collaborative-Inquiry Learning (Collin) model in developing 21st century critical thinking skills, which contribute to sustainable human development in the era of digital transformation.Method: The study was conducted in stages: preliminary study, prototype design, and formative evaluation. The products developed include model books, student’s book, and teacher’s book designed to support collaborative inquiry learning. Validation was carried out by education experts, colleagues, and practitioners, while the practicality test was obtained from teachers and students’ feedback.Results: The validation results showed a very high level of validity with an average score: model book (0.85), teacher’s book (0.85), and student’s book (0.82). The practicality from teachers resulted in a score of 89.27 for teacher’s and student’s book. The practicality from students resulted a score of 94.82 for student’s book. All instruments were declared feasible and relevant to be applied in 21st century learning.Conclusion: The Collaborative-Inquiry learning model is declared valid and practical to be applied in learning, especially in developing students’ critical thinking skills. This model supports active and reflective learning needed to form human resources that are adaptive, collaborative, and ready to face global challenges sustainably.

Indonesian EFL teachers’ English competency has been in the spotlight due to their unsatisfactory achievement. This reality has been observed during their practices in the classroom. This article aims at reporting the results of Indonesian EFL teachers’ perception of their productive English skills, speaking and writing. A mixed method was employed by focusing on introspective method. Quantitative data were obtained through a closed-ended questionnaire filled in by 206 secondary school teachers and analysed using SPSS software. Ten randomly selected teachers were interviewed to confirm the quantitative data. The findings show that EFL teachers’ speaking and writing skills are at a moderate level (68.62-71.70) and (67.83-71.18), respectively. Interview results indicate a low intensity of spoken English use in the classroom, which is less than 50%. This occurred for two main reasons: the students’ low ability to understand teachers’ talk/explanation and the teachers’ declining speaking ability. Meanwhile, only 2 of 10 teachers taught writing by following the steps of the writing process. However, at the interview session, the teachers rated themselves for speaking from 6-9 and for writing from 5-9. All teachers agreed that training to improve their English proficiency was highly important; this could be realised through the MGMP program. The results of these data will be used to develop a prototype of the Competency Test for Indonesian English Teachers (CTIET) to develop EFL teachers’ sustainable English proficiency.
