Abstract :

This study aimed to develop and validate the K to 12 based instructional material in chemistry for Grade 11 learners. The study was conducted to supplement the learning materials General Chemistry for Senior High School learners of Taytay Senior High School.A descriptive-evaluative method and qualitative approach are used in the study. Through random sampling, ten teacher-respondents from the different secondary schools in the Division of Rizal served as experts. These expertsevaluated the instructional material through a Focus Group Discussion (FGD). Fifteen (15) grade 11 learner-respondents were asked to assess the instructional material to determine the level of its acceptability in terms of objectives, contents, language and style, usefulness and organization, and presentation based on their perception. The evaluation happened after the exposure of the learner-respondents from the material. The experts evaluated the instructional material in the qualitative discussion. To discuss how the learner-respondents and teacher-respondents perceived the developed material, a qualitative discussion was applied.The instructional material is 'Very Highly Acceptable' as perceived by the learner-respondents in terms of objectives, content, language and style, usefulness, and organization and presentation upon utilizing it for one semester. Based on the semi-structured interview, learners and teachers perceived the instructional material as a helpful teaching tool. The instructional materials in chemistry possess excellent material characteristics since the experts and learners perceived it as a helpful tool. Hence, the developed material can be used in teaching chemistry for grade 11 learners to achieve a higher learning outcome.
