Abstract

The rapid development of information technology has transformed the characteristics of students from the millennial generation to Generation Z. This shift requires teachers to design learning that not only focuses on content but also fosters creativity and 21st-century skills. This study aims to evaluate the effectiveness of training programs in enhancing teachers' ability to implement differentiated instruction based on Technological Pedagogical Content Knowledge (TPACK) in reading and writing skills. The research employed a quantitative approach with a pre-experimental design using the one-group pretest-posttest model. The research subjects consisted of 41 participants, including teachers and school principals, selected through purposive sampling. Data were collected through observation, interviews, and documentation, using observation sheets and interview guides as instruments. The collected data were analyzed using qualitative thematic analysis. The results showed a significant improvement in teachers' understanding of integrating technology and pedagogy into differentiated learning. Teachers were able to design adaptive, interactive, and student-responsive literacy instruction. The findings underscore the importance of TPACK-based training in strengthening teachers’ competencies to meet the demands of 21st-century education. The study implies the need to reinforce TPACK-based training programs as a strategy to improve teacher professionalism.

Abstract

This study aims to improve students’ vocabulary mastery through the use of crossword puzzles in a classroom action research setting conducted in two cycles. The participants were 25 seventh-grade students at SMP Negeri 2 Karau Kuala, whose initial vocabulary proficiency was identified as low based on the pre-test, with the majority scoring within the fair and poor categories. The intervention involved implementing crossword puzzles as a learning medium designed to enhance students’ engagement, motivation, and retention of vocabulary through active learning strategies. Data were collected through pre-tests, formative tests, post-tests, questionnaires, observations, and field notes. The results of Cycle 1 showed a moderate improvement, with students beginning to demonstrate higher levels of participation and vocabulary recall, although some still struggled with understanding instructions. After revising the lesson plan and improving instructional clarity in Cycle 2, students’ vocabulary mastery increased significantly, as evidenced by the rise in students who achieved ratings of 3 and 4 and the absence of students in the lowest category. Qualitative findings also revealed enhanced confidence, reduced learning anxiety, and more collaborative classroom interactions during the learning process. Overall, the study concludes that crossword puzzles are an effective and engaging medium for improving vocabulary mastery among junior high school students. These findings suggest the need for further exploration of digital crossword tools, long-term retention effects, and the application of similar strategies to other language competencies.
