EVALUATION ON THE LEVEL OF EFFECTIVENESS ON THE INTEGRATION OF REPRODUCTIVE SYSTEM IN SCIENCE 5 BASIS FOR PROPOSED INSTRUCTIONAL MATERIAL

Abstract

The main objective of this study is to evaluate the effectiveness of integrating the reproductive system into the Science 5 curriculum, which will serve as a basis for the development of proposed instructional materials. The study aims to identify the most suitable instructional materials for teaching the reproductive system effectively. This will assist in enhancing the teaching methods of Grade 5 Science teachers, ultimately improving the overall quality of instruction and student learning outcomes. The researchers employed a descriptive design and quantitative methods to assess the level of effectiveness of integrating the reproductive system into the Science 5 curriculum. A stratified random sampling technique was used to select an equal number of male and female Grade 5 students from each section, with a total of 42 respondents. The statistical tools used in the study included frequency and percentage distribution, weighted mean, t-test, and ranking to analyze the data and draw conclusions about the effectiveness of the integration. The study revealed that the integration of the reproductive system into Science 5 was effective for both male and female students in terms of teaching methodology, knowledge, comprehension, and health. There was no significant difference between male and female students in relation to these variables. The researchers identified several barriers faced by both male and female respondents, including the complexity of terminology, lack of visual materials, insufficient prior knowledge, embarrassment or taboos, and fear of asking questions. In response, the science teachers implemented several solutions, such as breaking down complex terms into simpler components, promoting peer teaching to correct misunderstandings, providing pre-reading materials or videos to prepare students, creating a safe and respectful classroom environment for open discussions, and incorporating visual aids like educational posters or 3D models. The researchers identified effective instructional materials that science teachers can use to teach Grade 5 students about the reproductive system. The theoretical framework for the study is the ASSURE model, modified by Jiwak Raj Bajracharya (2020), which is a procedural, cyclical, and classroom-centered instructional design. The results of the study will serve as a guide for teachers in developing appropriate and effective instructional materials for their students. Additionally, the study demonstrates the importance of teaching Grade 5 students about the reproductive system, promoting body care, and preparing them for puberty, as emphasized by Maisie (2019).
