Construction and validation of outcomes-based worktext in Calculus

Abstract

This study focused on the development of an outcomes-based work text in Calculus, and determines its level of acceptability. The basis in the development of the work text was the revised outcomes-based syllabus of the course Calculus. Prerequisite courses such as algebra, advanced algebra, trigonometry, and analytic geometry taken by students based on their curriculum were identified. The revision of the syllabus was done by the Mathematics faculty members, recommended by the Chairman of the Department and approved by the Dean of the College of Arts and Sciences. The content of the course was based from CMO#19 s. 2007. The developed outcomes-based work text followed the ADDIE (Analysis, Design, Develop, Implement and Evaluate) model . The work text was validated by the faculty members in Mathematics who are experts in the field. The work text has the following parts; desired learning outcomes, recall, motivation, activity, lesson proper, skills building/application, generalization, reflection, and assessment. The respondents chosen purposively in evaluating the acceptability of the work text were the students enrolled in the course Calculus. The acceptability of the work text was rated with the following criteria: Content (M=3.37, SD= 0.54) Organization (M=3.46, 0.56) Style and Presentation (M=3.26, 0.68) and Activities (M=3.37, SD 0.44). All these criteria were rated moderately acceptable by the respondents. Based on the findings, with the revision in the curriculum by the Commission on Higher Education (CHED), from content-based curriculum to competency-based or outcomes-based curriculum, instructional materials should also be aligned to curricular change.
