Printed materials such as worktext and textbooks are considered the best instrument in improving transfer of learning since these materials can simulate a human facilitator to teach efficiently and effectively. This study aimed to develop and produce a computer generated instructional materials (CGIM) in College Geometry. The first phase of the study is assessment. It involved eighty-three (83) Bachelor of Elementary Education students. This research utilized an 80-item researcher-made test. Statistical tools employed were percentage, mean, standard deviation, and t-test for one sample. The second phase is development and production using document analysis methods. The result of the first phase shows that students have significantly low competencies in all the topics of College Geometry compared to the passing mean set by the PRC for teachers. The researchers developed a CGIM, specifically, the worktext paired with multimedia presentation. The parts were objectives, learning concepts, exercises, evaluation, and performance task. The topics included were logic and reasoning, geometry of shapes and size, angles and perpendiculars, triangle congruence, quadrilaterals, similarity, circles, and plane coordinate geometry. Every topic has corresponding subtopics. It is recommended that the CGIM will be used in Mathematics classes to improve students’ achievement, habits of mind, and problem solving skills.
