Effectiveness of TPACK-Based Multimodal Digital Teaching Materials for Mathematical Critical Thinking Ability

Technological Pedagogical Content Knowledge (TPACK)-based multimodal digital teaching materials need to be developed to maximize the implementation of learning in the era of technological and digital advances. This study is a pre-experimental one-group pretest-posttest design to analyze the effectiveness of learning by utilizing multimodal digital teaching materials for TPACK-based analytical geometry courses to improve mathematics critical thinking skills of fourth-semester students. The students were from the mathematics education study program at Universitas Muhammadiyah Sorong. Furthermore, the instrument used in collecting research data is a mathematical critical thinking skills test. The research data were analyzed with descriptive statistics and N-Gain. The results showed that implementing learning using multimodal digital teaching materials for analytical geometry courses with TPACK-based was quite effective. It increased mathematical critical thinking skills by 2.24 (56.11%), and the average N-Gain value was 0.62 (62%) which was included in the medium category.
