OPTIKS-PACK, a set of self-instructional modules on selected topics in Optics for tertiary students, is developed and evaluated in this study.OPTIKS-PACK had the following modules: Module 1 - Reflection, 2 - Refraction, 3 - Thin Lenses, 4 - The Wave Nature of Light, and 5 - Interference and Diffraction.This study used six instruments. Five of these were developed by the researcher herself. This package had five modules with corresponding 5 sets of pretest and posttest. It also contained a set of summative pretest and summative posttest. The pretest was a parallel form of the posttest. The effectiveness of the modular approach was measured by the scores of the student-respondents in the summative pretest and the summative posttest of the OPTIKS-PACK.The modules were evaluated in terms of content and instructional characteristics. The content characteristics included the following dimensions: objective, clarity, and relevance. The instructional characteristics included design, extent of students' interest and participation, effectiveness, suitability, and testing method.The study used the pretest-posttest non-equivalent group experimental design and the descriptive-evaluation research design. It was divided into 3 stages: planning, development, and try-out stage. The planning stage involved the design and detailed writing specifications of the modules. The development stage included the construction and testing of apparatus and materials needed, writing of the modules, and internal evaluation of the modules by Physics professors. The try-out stage covered field testing of newly-developed self-instructional units, evaluation of the modules by students in the experimental group and Physics instructors, analysis of the try-out results, and final modification of the modules.Three groups of respondents were involved. The experimental group, composed of 20 2nd year Engineering students, tried out and evaluated the modules. The control group, under the conventional method of teaching Physics, was composed of 27 Civil Engineering students. Seven Physics instructors read and evaluated the modules.The experimental group achieved significantly higher than the control group. The difference was due to the experimental treatment which was the modular instruction approach. The student respondents rated the OPTIKS-PACK as excellent in terms of content and instructional characteristics.The OPTIKS-PACK was excellent in terms of its objectives, clarity, relevance, design characteristics, effectiveness, and testing method. The extent of students' interest and participation was rated very good. The Physics instructors were unanimous in their evaluation of the set of modules. There was a highly significant correlation among the Physics instructors' evaluations.
