ABSTRACT

This study aimed to develop, validate and assess the acceptability of supplemental instructional material in oral communication in context that can serve as a useful tool for both teachers and students in senior high school. The study used the descriptive research method which includes the development, validation, and the assessment of acceptability of the supplemental material. In the development stage, the research developed the supplemental instructional material anchored to the most essential learning competencies established by the department of education. In the validation stage, twenty-two expert evaluators from the Borongan City Division served as the respondents, one english supervisor, seven school heads, seven master teachers, and seven oral communication teachers. They were selected to validate the supplemental instructional material in terms of its usability, consistency, curriculum alignment, objectives, content, presentation, and evaluation. The validation of the experts revealed that the proposed supplemental instructional material in oral communication received high rating across the criteria with grand mean scores ranging from 4.61 to 4.77 indicating “Highly Valid” evaluations. A total of eighty student-respondents as well as the twenty-two experts were able to assess the acceptability of the supplemental instructional material in terms of objective, format, content, organization, language, and usability. They rated the developed instructional material with grand mean scores ranging from 4.31 to 4.41. This concrete result can contribute to improving the quality of instruction, particularly in oral communication in context.

Key words: Development, Validation, Acceptability, Supplemental Instructional Material
