THE EFFECTIVENESS OF MODIFIED STRATEGIC INTERVENTION MATERIAL (MSIM) IN ENHANCING SCIENCE PERFORMANCE OF GRADE 10 MODULAR DISTANCE LEARNER Rationale Effective teaching-learning process has always been the aim of any educational institution. Regardless of the teachers’ age, gender and length in service, there will always be a need to adopt, improve and improvise teaching strategies to adapt to the ever-changing world of the learners. However, the outbreak of COVID-19 resulted in a widespread disruption such as travel restrictions, closure of schools and global economic recession. The Philippines has adapted the new normal form of education at present, and continuous innovations of educators and active involvement of other stakeholders are the driving force for its success. For the continuity of education and for every school to still attain its mission and vision which is to provide quality education to every Filipino learner, the Department of Education implemented Distance Learning Modalities. Distance Learning refers to a learning delivery modality, where learning takes place between the teacher and the learners who are geographically remote from each other during instruction. (Quinones, 2020) Modular learning is the most popular type of Distance Learning. In the Philippines, this learning modality is currently used by all public schools because according to a survey conducted by the Department of Education (DepEd), learning through printed and digital modules emerged as the most preferred distance learning method of parents with children who are enrolled this academic year (Bernardo, J). This is also in consideration of the learners in rural areas where internet is not accessible for online learning. This new normal in education is a great challenge for Science teachers to facilitate effective teaching- learning process and enhance students’ scientific literacy. It is also difficult for students to understand science concepts especially without the actual on-site facilitation of teachers. This situation calls for educators to create intervention materials to improve the students’ performance in Science. In this time of pandemic wherein both teachers and students are facing challenges, positive learning outcomes does not only depend on the teacher’s mastery of the subject matter but also the teacher’s innovations and creativity. It is inevitable for teachers to continually innovate intervention materials as well as strategies to assure continuity of learning. Through the use of strategic intervention materials, the teachers can capitalize on the strengths and improve learners’ performance. Theories/Concept supporting the rationale This study supports the Theory of Holmberg (1989) that calls for foundations of theory construction around the concepts of independence, learning, and teaching. Holmberg summarizes his theoretical approach by stating that: Distance education is a concept that covers the learningteaching activities in the cognitive and/or psycho-motor and affective domains of an individual learner and a supporting organization. Bumgarner (2017) presented that Contextualized Teaching and Learning Approach rooted in the constructivist approach to teaching and learning. Constructivist theory is usually associated with Jean Piaget, and he believed that pupils learn concepts and construct meaning through interaction and interpretation of events in their environment. However, the application of the CTL Approach was first Independent variables. Amidst the challenges in education brought about by this pandemic, it is imperative for teachers to use sound strategies to enhance competence of learners. This study therefore aims to contribute knowledge in relation to modular distance learners’ academic performance in Science by testing the effectiveness of Modified Strategic Intervention Material (MSIM) to enhance and give remedy on the least mastered competencies. Science teachers must equip every student with the necessary scientific skills that will help them perform in the different learning areas in the curriculum. Conceptual Framework Independent variables Learning gaps in modular distance delivery instruction in Science Development and utilization of Modified Strategic Intervention Material (MSIM) Dependent variable Science performance of grade 10 modular distance learners Fig1. Dependent Variable as affected by Independent Variables 5 It is shown in Figure 1 how the dependent variable is affected by the independent variables. The Independent variables include the leaning gaps in modular distance delivery instruction and the development and utilization of modified strategic intervention material. On the other hand, dependent variable comprises the Science academic performance of grade 10 modular distance learners. The effectiveness of MSIM will be determined by the academic performance of learners. Statement of the Problem/Purpose This study aims to evaluate the effectiveness of Modified Strategic Intervention Material (MSIM) in enhancing Science performance of Grade 10 Modular Distance Learners. Specifically, the study attempts to answer the following questions: 1. What is the level of students’ academic performance on the least mastered competency in Science 10 on the control and experimental groups before and after the utilization of MSIM? 2. Is there a significant mean difference between the students’ academic performance on the control and experimental groups before and after the utilization of MSIM? Hypothesis The researcher is guided by the following hypothesis: There is no significant mean difference between the groups of learners without and with the utilization of MSIM. Methods: Design, Sampling, Instrument, Procedure and Data Analysis The pretest-posttest quasi-experimental design will be employed to carry out this study. The participants of the study will be forty-six (46) grade 10 modular distance learners of Rizal Integrated National High School SY 2021-2022 selected through purposive sampling. The researcher will design and construct strategic intervention material using contextualization and localization and material scaffolding strategies. The modified strategic intervention material will be validated. To test the effectiveness of the MSIM, a validated assessment tool will be administered as pretest before utilizing the MSIM and as post-test after the intervention. The data to be gathered in this study will be tabulated, treated, analyzed, and used as bases for interpretation. Standard statistical procedures and formula will be used to arrive at a reliable conclusion. The researcher will use Mean, Standard deviation, Minimum, Maximum value, Mean Percentage Score (MPS) as statistical treatment to process the data and to arrive at interpretation of each item in the instrument. Paired t-test and Independent t-test will be employed to compare the two mean scores after the utilization of MSIM. References Ambayon, C. M. (2020).
