Abstract—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.
