DEVELOPMENT AND VALIDATION OF OUTCOME-BASED INSTRUCTIONALMATERIALS (OBIMs) IN MATHEMATICS 2

Abstract

This study aimed to develop and validate Outcome-Based Instructional Materials (OBIMs) in
Mathematics 2. Anent to this, the researchers determined the least-learned skill in the first
quarter periodic test of Grade 2 pupils. It was made as basis in crafting and designing the
Outcome-Based Instructional Materials. The researchers used descriptive-developmental design
where purposive sampling was utilized since the participants of the study were chosen based on
the criteria set. There were six (6) participants who evaluated the content of OBIMs. The
research instruments used in the study were survey questionnaires which underwent validation
by experts. They were the tools used in the validation of the content of the OBIMs. The data
gathered from the survey questionnaire were treated using weighted mean for analysis. Results
revealed that the content of the developed OBIMs was valid meaning its objectives, technical
quality, organization or flow of the activities, language arts content and alignment to the K-12
curriculum are very satisfactory. The results further suggest that the OBIM is suitable and
appropriate for the pupils to master the competency in Mathematics 2.
