Management of Mathematics Learning Based on Interactive Digital Worksheets to Improve Students' Critical Thinking Ability

Abstract

The use of interactive digital technology in learning is an alternative strategy to create joyful learning activities. Therefore, interactive digital worksheet requires development by considering the critical thinking skills of elementary school students. This research determined the interactive digital media worksheet necessity based on critical thinking skills, compiling design, feasibility identification, and effectiveness test of the interactive digital media worksheet based on critical thinking skills for elementary school students. This research and development applied seven steps: (1) potential and problem identification; (2) data collection; (3) product design; (4) design validation; (5) design revision; (6) product test; and (7) product revision. The researchers collected the data with interviews, observations, questionnaires, and tests. The research results found the necessity of interactive digital student worksheets in managing mathematics learning to improve students' critical thinking skills. The interactive digital LKS design was based on critical thinking skills. The development considered the three components, such as (1) Planning; (2) implementing; and (3) evaluating. Planning consists of (1) the analysis of student characteristics; (2) the analysis of learning achievements (CP); (3) the determination of the learning objectives (TP) and the learning objective flow (ATP) and the assessment; (4) the selections of media, learning methods, and teaching materials. The implementation of the interactive digital student worksheets in learning was based on the problem-based learning model and formative and summative tests for the evaluation. The expert validation found the interactive digital worksheet was valid and reliable. The teacher responses reached the percentage of 87.5% while the student with 90%. The product test obtained an average of N-gain for the control group was 0.31 while the experimental group was 0.50, indicating an increment of students' critical thinking skills in mathematics. Thus, interactive digital worksheet implementation is useful in managing learning. The implementation was also useful for further development to manage various challenging activities and to realize meaningful learning.
