The use of Multimedia of geometry Based on Van Hiele Thinking Theory: An Alternative to Improve Critical Thinking Skill of Elementary School Students

Abstract

This research was aimed to explore the learning process and the perception of student toward multimedia of geometric based on Van Hiele’s thinking theory and to inspect the effectiveness of multimedia of geometry based on Van Hiele’s thinking theory used in the process of mathematics learning. This research was implemented in SDN Mojoroto 6 Kediri City, Indonesia in 2021/2022 academic year. The samples were 33 at the age of 11-12 years old. This study was designed with mixed research. The data were collected through the instruments of observation, interview, and critical thinking sheets. The results of this research have indicated that the implementation of multimedia of geometry based on Van Hiele’s thinking theory was running properly. Multimedia of geometry based on Van Hiele’s thinking theory can be received in the mathematics learning process. The students became more motivated in learning, the learning process was more interesting and meaningful, while the results of the critical thinking skill of students have indicated significant improvement after the implementation of multimedia of geometry based on Van Hiele’s thinking theory compared to the prior condition.
