Abstract

Mathematics learning in Class X SMAN 1 Pelangiran remains suboptimal due to the dominance of lecture-based methods and conventional teaching materials, resulting in passive student engagement and low learning outcomes (only 41.38% completeness). This study aimed to develop a TPACK-based Electronic Student Worksheet (E-LKPD) for geometry materials to enhance learning effectiveness. TPACK integrates technological, pedagogical, and content knowledge, while E-LKPD promotes interactive, technology-assisted learning. Using a Research and Development (R&D) approach with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), the E-LKPD was designed with multimedia elements such as videos, quizzes, and digital navigation. Expert validation results indicated high feasibility: material (95.4%), media (80%), and language (90.55%). Practicality tests showed the E-LKPD was very practical for teachers (90.95%) and students (85.25%). Effectiveness was demonstrated through an increase in students’ average scores from 17.31 in pre-test to 61.21 in post-test, with and N-Gain of 57%. The findings conclude that the TPACK-based E-LKPD is valid, practical, and effective in supporting more interactive and adaptive mathematics learning.

Abstract

I The implementation of the Independent Curriculum through the use of the Independent Teaching Platform (PMM) at SMK Negeri 6 Padang faces a number of challenges, such as teachers' lack of understanding of the curriculum, limited content in the PMM feature, and limited internet access in schools. This study aims to analyze the use of self-development, teaching, and inspiration features in the implementation of the Independent Curriculum in vocational schools. The results showed that although teachers have taken advantage of the PMM feature, only a few features such as self-training, performance management, CP/ATP, teaching tools, and inspirational videos are used optimally, while other features have not been maximized due to limited content and are still in the development stage. Factors that support the use of PMM include professional development features, collaboration in the development of teaching materials, and career opportunities, while obstacles faced include limited technology skills, limited time, and lack of motivation for teachers to participate in training. To overcome these barriers, it is necessary to conduct regular training to improve teachers' digital skills, proportionate workload management, improve PMM features, and develop materials relevant to learning needs, as well as increase teachers' awareness that training and seminars are not just for certification.
