Abstract

The study aimed to determine the effectiveness of the teacher-made science strategic intervention materials to enhance the academic performance of the Grade 12 students in intervening the least learned competency focusing on the descent with modification topic. The respondents consisting of fifteen students (15) were given an intervention on the identified lowest least-learned competency. The fifteen (15) items of a teacher-made questionnaire in pre-test and post-test were used in collecting data for the study. The study revealed a significant difference between the pre-test (45.33) and post-test (75.56) scores of the respondents in the descent with modification topic having a t-test score of -7.41 at .000 significant level of performance. This implies that the strategic intervention material (SIM) was significantly effective in intervening the least learned competency in Biology II subjects.

Introduction

The purpose of including science in the curriculum is to attain a level of "scientific literacy" among the populace to allow them to engage as members of contemporary societies. The goal of science is to provide every Filipino student with a useful comprehension of scientific ideas and concepts applied to actual circumstances, as well as get scientific abilities, perspectives, and principles required to assess and resolve daily issues (A Framework for K-12 Science Education Practices, Crosscutting Concepts, and Core Ideas, 2012). Teachers can use assessment data to create individualized plans for struggling students, thereby personalizing a student's learning journey (Diaz, 2023). By leveraging assessment data, educators can tailor instruction to meet the specific needs of each student, fostering a more effective learning environment.

The Department of Education (DepEd) has lobbied for the modification of the laws as part of the government's efforts to address the perceived requirements of the education sector. They use the "Enhanced K to 12 Basic Education Program" to implement a basic education curriculum (Capate and Lapinid, 2015). Teachers must be sufficiently creative to meet the needs of their students considering the changes to the basic education curriculum. To raise the standard of education in the Philippines, educators must work twice as hard. DepEd also recommended a curriculum known as Strategic Intervention Material (SIM) after considering these factors. The purpose of introducing this educational material was to enhance students' performance across several subject areas. Its main goal is to support elementary and secondary students' successful learning in public schools. In addition, the teachers received training and a workshop on creating this instructional material through the DepEd Memorandum No. 117, series of 2005.

Strategic Intervention Materials (SIMs) in science are instructional materials designed to improve the academic performance of learners. These materials are used to teach basic concepts and skills, particularly in areas where students may have difficulty mastering competencies during regular classroom activities. SIMs are created based on the learning competencies that students need to improve and are intended to increase their academic performance in science. They can be in various formats, including electronic materials, and are used to aid both traditional and online learning. Studies have shown that SIMs can be effective in improving the academic performance of learners in science (Acera, 2022).

The first quarter examination results show that the achievement rate for grade 12 students in the Magpayang National High School, School Year 2023– 2024 is 10%, which is less than the 75% passing rate. This demonstrates that remedial instruction on a regular basis, more teaching resources, and instructional techniques like peer grouping are insufficient to remedy low performance in certain areas (Dy, 2011). Nevertheless, having enough and readily available instructional resources makes science instruction more effective. It is the duty of the science teacher to provide and supply the resources needed for science classes.

This study aims to find out the effectiveness of using Strategic Intervention Material (SIM) in intervening with the least learned competency in Biology II subject focusing on descent with modification. Specifically, this study sought to answer the following questions: 1. What are the least learned learning competencies in Biology II for the first quarter of the school year 2023-2024? 2. What is the level of performance of the students as measured in pre-test and post-test? 3. Is there a significant difference between the pretest and post-test of the students after using the Strategic Intervention Material (SIM)? The purpose of this study was to determine the effectiveness of teacher-created science Strategic Intervention Material (SIM) to intervene the leastlearned competency in Biology II subject focusing on descent with modification topic. This was conducted at Magpayang National High School in the first quarter of the school year 2023-2024. Thirty (30) grade 12 students were the study's respondents. To address the research topics, a one-group pre-testpost-test research design was used. Furthermore, a 15-item test questionnaire created by the researcher was used to evaluate the student’s performance.
