Micro Learning-based Module: A Teaching Tool to Enhance Students’ Competence in Grade 9 Trigonometry

Abstract

Globally, as the education field gear towards recovery from the Covid 19 pandemic, there is a must to adapt teaching strategies that will equip the teachers to continuously provide quality and engaging activities in a simplified manner that will bring out the best of the students. This paper describes the effectiveness of microlearning-based module as a teaching tool in enhancing students’ competence in Trigonometry. Data analysis gave results that there was mean difference of of 4.46 in illustrating, 5.02 for identifying, and 4.5 in solving after being exposed to the created learning material. The posttest result suggests that microlearning-based useful tool for enhancing students’ competence of the 9th – grade students in Trigonometry. Level. The hypotheses that claimed there was no significant difference between mean scores in the pretest and post- test of the three competencies in Trigonometry was negated. According to the results, students’ competence in Trigonometry were enhanced in terms of mean scores. Future student performance in the three competencies in Trigonometry can be projected to be better and more satisfying if this trend holds if it does. The created learning material can be credited with enhancing students' competence in illustrating the following topics: the six trigonometric ratios, the trigonometric ratios of special angles, and angle of elevation and angle of depression. Also, the microlearning module can improved the competency of identifying the trigonometric ratio that can be used in relating the angles and sides of a right triangle. The designed learning material can help the students enrich their solving skills such as solving the missing parts of a right triangle, evaluating trigonometric expressions of involving special angles, and problem solving involving right triangle, angle of elevation, and angle of depression. Hence, it is highly recommended that the school use this learning material to encourage effective teaching and quality learning.
