Interactive E-book Design Assisted by Heyzine Flipbooks with the Learning Cycle Model: An Analysis of Product Effectiveness Reviewed from Students' Critical Reasoning Ability

Abstract

The purpose of this study is to describe the effectiveness of the Henzine Flipbooks-assisted Interactive E-book design product with the Learning Cycle Model in improving students' critical reasoning skills. This research method is research and development research with the ADDIE model, but in this study it is focused on the Implementation stage so that the analysis of product effectiveness can be achieved. Product trials were conducted with one group pretest posttest design. The research population was fifth grade students of SDN 200106 Padangsidimpuan. The research sample was fifth grade students of SDN 200106 Padangsidimpuan consisting of 22 students with 8 male students and 14 female students. The research conducted showed the results of learning management during 4 meetings with an average value of 4.35 (good category). Furthermore, the achievement of students' critical reasoning abilities in the pretest with an average value of 59.6 and posttest 75.9 there was an increase in the value from pretest to posttest by 27.32% through inferential statistical analysis obtained a significance value of 0.00 which is smaller than the alpha level (0.05) which indicates there is a significant difference in the average results of the pretest and posttest, as well as the acquisition of the N-gain index of 0.40 which indicates that the achievement of improvement from pretest to posttest in the moderate category. Thus it is concluded that the Interactive E-book Assisted by Henzine Flipbooks with the Learning Cycle Model to improve students' critical reasoning abilities. The results of this study imply that the application of the Learning Cycle Model assisted by the Interactive E-book Heyzine Flipbooks is effective in classroom learning because it is able to increase student engagement, create meaningful learning experiences, and significantly develop critical reasoning abilities through a structured process of exploration, discussion, and reflection.
