Developing Mathematics Module Based on Literacy and Higher Order Thinking Skills (HOTS) Questions to Train Critical Thinking Ability of High School Students in Mojokerto

Abstract

This research aims to describe the process and results of the developing mathematical module based on literacy and higher order thinking skills (HOTS) to train the critical thinking ability of high school students in Mojokerto that are valid, practical and effective. This research is a development research that uses an adopted Tessmer development model. The subjects of this research were 11th grade students at SMAN 1 Puri Mojokerto. Three students with high, medium and low mathematical ability for the One to One stage. In the Small Group stage, nine students, with the provisions of three students with high mathematical ability, three students with middle mathematical ability, and three students with low mathematical ability. While the field test stage, the research subjects were 30 students with heterogeneous mathematical ability. The students' mathematical abilities were seen from the first semester of academic year report scores and in each stage. The development process starts from the preliminary stage, which is conducting literature studies about mathematics module based on literacy and HOTS questions, this process then followed by contacting the headmaster and teachers regarding the research schedule. The next stage is the self-evaluation, this stage consists of the analysis and design stages that analyze the students as the subject of this research and material used in the research. The materials used are Mathematical Induction, Linear Program, Matrix and Geometry Transformation, and designing a prototype. The third stage is prototyping, this stage consists of experts review, one to one, small group and field test. In the expert review, a prototype II was produced which were said to be valid. Whereas in the one to one, three students were tested and III prototypes were produced. The small group, a trial was conducted and a prototype IV was produced. Then the field test, testing and produced mathematical modules that met the valid, practical and effective. The results of this study are mathematics module based literacy and HOTS questions to train critical thinking ability that meet the validity criteria with valid categories, fulfill practical criteria with a very practical level. As well as meeting the module's effectiveness criteria by having students' critical thinking ability either high or high.
