Abstract

This study was led to decide the effect of utilizing manipulatives in learning fraction. The examination demonstrated the effects of those manipulatives on learning fraction. The information was gathered from the sum number of 62 respondents, 31 students from the experimental group and 31 students from the control group, with the guide of the approved and validated test questionnaire. Information was investigated and translated utilizing the Average Weighted Mean and T-test as statistical tools. A pre-test and post-test were utilized to decide the results of utilizing manipulatives in the learning area. Data demonstrated that there was a significant difference in the utilization of Manipulatives for Learning Fraction among first-year elementary students. Some recommendations were also included in this study.

Abstract

Abstract: This study aims to analyse the validity, practicality, and effectiveness of Scratch learning multimedia in improving students' mathematical literacy skills. This research method is Research and Development (R&D) with ADDIE development model (Analyze, Design, Development, Implementation, and Evaluation). The sample of this research was VIII C students of SMP Negeri 1 Tegalrejo as many as 32 students. The sampling technique used purposive sampling. The data collection techniques were interviews, questionnaires, observation sheets, and tests. The results showed that Scratch learning multimedia was in the very valid category with the acquisition of 80% material validity and 83.56% media validity. Scratch learning multimedia is classified as a very practical category with a percentage of 81.87% based on student responses and 98.33% teacher responses. In addition, this multimedia is effective for improving mathematical literacy skills as evidenced by the difference in pre-test and post-test scores, with an N-Gain value of 0.43 including the moderate category. It can be concluded that the development of Scratch learning multimedia is valid, practical, and effective to improve students' mathematical literacy skills.         Keywords: mathematical literacy, scratch multimedia, statistics.
