EFFECTIVENESS DEVELOPMENT STUDENT WORKSHEETS BASED ON CAT TO IMPROVE MATHEMATIC UNDERSTANDING ABILITIES STUDENTS OF CLASS VI SD METHODIST-12 MEDAN

Abstract

Basically, the ability of Mathematical Comprehension is an ability that can be trained for every student. Students Worksheet (LKPD) is a learning aid in the learning process. One of them is LKPD based on CAT (Computer Assisted Test). CAT is a learning medium that is designed to be used to develop interactive LKPD related to integer arithmetic operations. This research method is the method of Research and Development. The subject of this research is class VI SD Private Methodist-12 Medan Academic Year 2019/2020. The variables to be measured are proof of important analytical and experimental functions and / or characteristics (TKT 3) which includes the accuracy of LKPD based on CAT design, comprehension ability. student mathematics and the effectiveness and efficiency of use. Based on the expert's judgment, the material in this study was carried out by one validator in the field of mathematics education. The aspects of the assessment are the feasibility of content, presentation, language and graphics. The average score of the four aspects was 88.02% in the Very Good category. Judgment of media experts that the aspects of media feasibility, content feasibility, presentation and graphic. The average value of this aspect is 90.73% in the Very Good category. The assessment of media experts that the aspects of media feasibility, content feasibility, presentation. The average value of these two aspects is 95.00% in the Very Good category. The results of the data analysis of the individual test responses showed that the aspects of content, objectives, feasibility, technical quality and attractiveness. The average value of these five aspects is 92.00% in the Very Good category. The results of the data analysis of the individual test responses showed that the aspects of learning content, objectives, feasibility, technical quality and attractiveness. The average value of these five aspects is 92.00% in the Very Good category. The results of the data analysis of the field test students' responses indicated that the aspects of the content, the objectives of, the feasibility, the quality of the technique and the attractiveness. The average value of these five aspects is 94.77% in the Very Good category. The results of the data analysis of the individual test students' responses showed that the aspects of content, objectives, feasibility, quality and attractiveness. The average value of these five aspects is 92.00% in the Very Good category.
