The Development of Module Based on Micro controller in Improving Student Computational Thinking Skills

Computational thinking is a method for solving problems using algorithms similar to techniques used in software programming. The purpose of this research is to examine the validity, practicality and effectiveness of micro controller-assisted modules. The type and design of the research includes the type of research (research and development) R & D that has been developed using Plomp’s research design through the following steps, namely preliminary research, prototyping phase, and assessment phase. Data collection uses several techniques, namely interviews, questionnaires, computational thinking tests. The instruments used are validation sheets, student anget sheets, and observation sheets. The feasibility of the module is measured using a validation sheet and to measure student interest in the product that has been developed using a student response questionnaire sheet. The results of the validity analysis of 89% were declared very valid obtained from the three validators, 92% practicality was declared very practical with practicality indicators in the form of student fluency in using the module, and effectiveness of 0.78 obtained from n-gain analysis which means quite effective and the results of the student response questionnaire sheet in the good category of 72%. The results of the analysis obtained show that the use of micro controller-assisted modules that are valid, practical, and effective in earth science courses can improve student computational thinking.
