Abstract

This study investigates the effectiveness of an e-booklet in improving students' scientific explanation skills in the human immune  system topic. A quasi-experimental design was employed, involving two groups: an experimental class using the e-booklet and a control class relying on conventional teaching methods. The study was conducted at SMAN 1 Leces Probolinggo, with 31 students in each group. Pretest and posttest assessments were used to measure scientific explanation skills, which were analyzed through statistical tests, including normality, homogeneity, t-test, and N-gain calculations. The results showed that the experimental class had a significantly higher improvement in scientific explanation skills than the control class. The N-gain score for the experimental class was 0.507, classified as moderate, whereas the control class scored 0.142, classified as low. The analysis of the three components of scientific explanation: claims, evidence, and reasoning indicated that the e-booklet was particularly effective in enhancing students' ability to construct claims and provide supporting evidence, while reasoning skills showed moderate improvement. Statistical analysis using the Mann-Whitney test confirmed a significant difference in posttest scores between the two groups (p<0.05), supporting the effectiveness of the e-booklet. The findings suggest that the e-booklet serves as an effective digital learning tool for fostering scientific explanation skills.

Based on these issues, this study was conducted to improve number recognition skills through basic geometric shapes.The objectives of this study were to determine: 1) Number recognition skills before implementing basic geometric shapes; 2) The process of implementing basic geometry to improve number recognition skills in each cycle; 3) Number recognition skills in group A of THEOBROMA II Kindergarten, Mumbulsari, Jember, after implementing games using basic geometric shapes in each cycle.This study is based on the premise that games using basic geometry can be used as educational teaching aids, and these games are an appropriate way to improve cognitive abilities in early childhood, especially in number recognition. Based on this assumption, the hypothesis is proposed that children's number recognition skills are expected to improve if the use of basic geometric shapes games in group A of THEOBROMA II Kindergarten, Mumbulsari, Jember, is implemented.This study used classroom action research. Data collection tools were observation and documentation. The data analysis techniques used were data reduction, data display, conclusions, and verification. The subjects or respondents in this study were 12 children from group A of THEOBROMA II Mumbulsari Kindergarten, Jember.ards.
