Abstract

Mathematics learning, particularly in the topic of fractions, often presents challenges for fourth-grade students due to its abstract nature and the lack of engaging instructional media. Therefore, this study aims to develop contextual problem-based animated video media to enhance students' understanding of fraction concepts and improve their learning motivation. The research employed the ADDIE development model. Data collection was conducted through questionnaires and tests. The questionnaires were used to gather feedback from experts and students, while the tests were designed to assess students' achievement in understanding fractions. Prior to use, the research instruments were piloted to ensure their validity and reliability. Validity was tested using the point-biserial correlation formula, whereas reliability was measured using the Kuder-Richardson 20 (KR-20) formula. Additionally, the difficulty level and discriminative power of test items were analyzed. The collected data were analyzed using quantitative descriptive analysis, qualitative descriptive analysis, and inferential statistical analysis (t-test). A normality test using the Shapiro-Wilk formula was conducted before the t-test to ensure the data followed a normal distribution. The findings indicate that the developed media met the criteria for feasibility and effectiveness in enhancing students’ learning outcomes. The use of contextual problem-based animated videos has proven to be an engaging and interactive alternative in mathematics instruction.

Abstract

This study addresses issues related to mathematics learning, specifically on the topic of the area and perimeter of flat shapes, which can enhance students' understanding and interest in learning mathematics. The purpose of this study is to develop the design and development of a Predict-Observe-Explain (POE) based E-Module product, assess the quality of the E-Module through expert evaluation, individual tests, and small group tests, and determine the effectiveness of the Predict-Observe-Explain-based E-Module media. This research uses the ADDIE development model (Analyze, Design, Development, Implementation, Evaluation), and data collection is carried out through interviews, questionnaires, and tests. The data analysis techniques used are descriptive quantitative analysis and inferential statistics. The results of the study show that the Predict-Observe-Explain based E-Module developed using Canva can be accessed through Google Drive. The assessment from content experts resulted in a score of 97.7%, instructional design experts 90%, and media experts 92.3%. The individual test, involving three students, scored 97.5%, while the small group test, involving nine students, scored 94.4%, both falling in the very good category. The t-test results showed a value of 21.70, which is greater than the t-table value of 2.052 at a 5% significance level with 27 degrees of freedom, thus rejecting H0 and accepting H1, indicating that the average post-test score of students is higher than the average in the KKTP, which is 87.86. Therefore, the Predict-Observe-Explain based E-Module has proven to be effective for teaching the topic of Area and Circumference of Two-Dimentional Shape’ss to fourth-grade students.

Abstract

Student learning outcomes in mathematics, particularly in data presentation, are still relatively low. This is due to the use of conventional teaching methods that are uninteresting and unsuited to students' learning styles, resulting in poor conceptual understanding and low motivation to learn. This study aims to create an ICARE-based animated video medium. This is a research and development (R&D) study using the ADDIE model (Analyze, Design, Develop, Implement, Evaluate). The research subjects include subject matter experts, instructional designers, learning media specialists, and 32 fourth-grade students. Data were collected using Likert scale questionnaires and multiple-choice tests, while the instruments used were questionnaire sheets and test sheets. Data were analyzed using quantitative descriptive statistics and a one-sample t-test. The results of the study indicate that the developed animated video media have excellent quality based on expert evaluations and student trials. In conclusion, the use of animated video media based on the ICARE model in data presentation materials can enhance students' conceptual understanding and learning motivation in fourth-grade elementary school. Implications suggest that the application of this media can serve as an innovative alternative to improve the quality of mathematics education and support more interactive and engaging learning methods for students.

Abstract

This research is motivated by the low dancing skills of deaf students due to the absence of learning media that are in accordance with their characteristics and learning styles. This research aims to develop learning media in the form of a E-Dictionary of basic Kecak dance based on Bisindo that is valid, feasible, and effective for use by deaf students. This research uses a development research approach with a systematic ADDIE model. The subjects involved included learning content experts, instructional design experts, learning media experts, and 9 deaf students in grade V elementary school. The results of the design expert assessment were 93.18% with very good qualifications, the results of the content expert assessment were 96.67% with very good qualifications, the results of the instructional design expert assessment were 95% with very good qualifications, the results of the media expert assessment were 95% with very good qualifications, the results of the individual trial were 92.35% with very good qualifications, the results of the small group trial were 95.83% with very good qualifications. The effectiveness test results obtained a tcount value of 23.056 while the ttable was 2.306, so H0 was rejected and H1 was accepted. So, it can be concluded that the E-Dictionary of basic Kecak dance based on Bisindo media effectively supports dance learning for deaf students. The implication is that this media can be an alternative tool in an innovative learning process to improve the skills of deaf students, while introducing them to local culture.

Abstract

Limitations in mathematics learning media have an impact on low student understanding and learning outcomes, particularly in the subject of flat shapes in fourth grade elementary school. This study aims to develop valid and effective digital worksheets based on ethnomathematics using endek tretes, tumpal, and jumputan woven fabrics to improve student learning outcomes. The development model used is ADDIE, encompassing the stages of analysis, design, development, implementation, and evaluation. The research subjects were 28 fourth-grade elementary school students. Data were collected through interviews, observations, questionnaires, and tests, and analyzed using qualitative and quantitative descriptive analysis, as well as paired-sample t-tests. The validation results indicate that this media is highly suitable for use, with scores of 90.90% from content experts, 91.67% from design experts, and 92.19% from media experts. Individual and small group tests yielded scores of 96.20% and 97.21%, respectively. The effectiveness test showed a significant improvement in student learning outcomes with a tvalue of 22.439 > ttable 1.703. Thus, this ethnomathematics-based digital LKPD has been proven to be valid, feasible, and effective for use in learning about flat shapes, and contributes to enriching the variety of meaningful learning media in elementary schools.
