Abstract

Elementary school students have a low understanding of the concept of protecting themselves from violence or sexual harassment, even though some students are familiar with body organs and how to maintain their hygiene. One of the causes is the lack of learning media for sexual education that is appropriate to the characteristics of lower-grade students. Based on this, the purpose of this study is to develop a Digital Storybook Assisted by Interactive Quizzes to Improve Understanding of Sexual Education in Second-Grade Elementary School Students. This type of research is development research using the ADDIE model. The feasibility of the product created was tested by 2 content experts and 2 learning media experts. 10 and 25 students conducted the practical test. The subjects of this effectiveness test were 30 people. The methods used to collect data included questionnaires and objective test methods. The instruments used to collect data were questionnaires and multiple-choice questions. The analysis methods used in this study were qualitative and quantitative. The results of the study validated the digital storybook by media experts (average score of 96.5%) and material experts (96.25%; very valid). The teacher's assessment was 4.78, and the student's was 4.76 (very practical). The effectiveness test showed a difference in average learning outcomes between the control and experimental groups after controlling for initial abilities. It was concluded that the use of digital storybooks with interactive quizzes significantly improved elementary school students' understanding of sexual education.

Abstract

The current condition of education indicates that elementary school students’ critical thinking skills in science in Indonesia have not yet developed optimally and remain a serious challenge, as reflected in science literacy achievement that is still below the international average. Therefore, this study aims to analyze the effect of a Problem-Based Learning (PBL) model supported by multimedia instructional materials on fifth-grade students’ critical thinking skills and learning interest in science. This study employed a quantitative approach using a quasi-experimental research design, specifically a pretest–posttest nonequivalent control group design. The population consisted of 313 fifth-grade elementary school students, from which a sample of 130 students was selected using random sampling techniques. Data were collected through tests and questionnaires, with research instruments comprising critical thinking tests and learning interest questionnaires. Data analysis was conducted using one-way MANCOVA with the assistance of SPSS 27.0 for Windows. The results indicate significant differences in students’ critical thinking skills and learning interest in science between those taught using the Problem-Based Learning model supported by multimedia instructional materials and those taught using the conventional Problem-Based Learning model. It can be concluded that the Problem-Based Learning model supported by multimedia instructional materials results in higher improvements in students’ learning interest in science compared to the Problem-Based Learning model. The implication of the research is that the application of PBL assisted by teaching materials can help students in learning.

Abstract

This study aimed to develop and examine the feasibility of a flipbook-based learning medium incorporating local wisdom from Balinese folktales for IPAS instruction, particularly for fifth-grade elementary school students. This study employed a research and development approach using the ADDIE model. The feasibility of the developed product was evaluated by two subject-matter experts and two instructional media experts. Practicality testing was conducted with five teachers and twenty-five sixth-grade students who participated in the trial and provided assessments of the flipbook. Data were collected using questionnaires and objective tests, with questionnaires serving as the primary research instrument. Data analysis techniques included quantitative descriptive analysis, qualitative descriptive analysis, and inferential statistical analysis using Analysis of Covariance (ANCOVA). The results showed that the flipbook achieved a validation score of 92.5% from media experts and 93.33% from content experts, indicating a very high level of validity. The practicality assessment yielded mean scores of 4.81 from teachers and 4.78 from students, categorizing the media as very practical for instructional use. Hypothesis testing revealed a highly significant effect on students’ learning outcomes. It can be concluded that the use of a flipbook-based learning medium integrating Balinese folktale local wisdom significantly improves the IPAS learning outcomes of fifth-grade elementary school students. The implication of the research is that the flipbook media containing local wisdom of Balinese folk tales that was developed can help students in learning.

Abstract

The low level of students’ critical thinking skills in science learning is primarily attributed to instructional practices that are still dominated by basic question-and-answer methods and limited discussions. This study aimed to analyze the effect of the Problem Based Learning (PBL) model assisted by mind mapping on elementary school students’ science critical thinking skills in terms of their self-efficacy. This research employed a quantitative approach using a quasi-experimental design. The population consisted of 324 fourth-grade elementary school students, and random sampling was used to select the research sample. Data were collected through questionnaires and essay tests, with self-efficacy and critical thinking tests serving as the research instruments. Data analysis techniques included descriptive analysis and analysis of covariance (ANCOVA). The results indicated that: first, there were significant differences in science critical thinking skills between students taught using the PBL model assisted by mind mapping and those taught using conventional learning models. Second, there was a significant interaction effect between the PBL model assisted by mind mapping and students’ self-efficacy on science critical thinking skills. Third, there were significant differences in science critical thinking skills between students with high self-efficacy who learned through the PBL model assisted by mind mapping and those who learned through conventional models.Fourth, there were significant differences in science critical thinking skills between students with low self-efficacy who learned through the PBL model assisted by mind mapping and those who learned through conventional models.
