ABSTRACT
The main thrust of this study was to develop and validate contextualized instructional material in Grade 9 Economics. This study followed the design and development research method. The respondents of the study, who were chosen through simple stratified random sampling technique, were 70 Grade 9 learners from Tanauan City Integrated High School, and 25 Araling Panlipunan secondary teachers from North and East District of the City Schools Division of Tanauan.
Using a four-point Likert Scale, simple mean, and t-test for independent samples, the findings revealed that the developed contextualized instructional material in Grade 9 Economics based on the assessment of the Araling Panlipunan teachers in terms of objectives, directions, topics, and practical exercises were all highly valid. Meanwhile, the level of acceptability of the developed contextualized instructional material in Grade 9 Economics was also highly accepted based on the assessment of the Araling Panlipunan teachers in terms of clarity, usefulness, presentation, and suitability. There was a significant difference in the academic performance level of the learners comparing the mean scores of the learners during the pretest and posttest.
It can be concluded that the developed contextualized instructional material in Grade 9 Economics evidently increased the acquisition of learning of Grade 9 learners based on the difference in their performance in the pretest and posttest. Thus, this is effective and acceptable for use as supplementary instructional material in teaching Araling Panlipunan-Economics.
