—— This study was focused on assessing the validation and implementation of learning modules in General Chemistry teaching in the three courses during the school year 2021-2022. It determined the performance level of the learners in General Chemistry before and after implementation of the said learning modules through a pretest and posttest. The level of performance of the General Chemistry learners during the pre-test was way below the 75% standard. The mean percentage score of the General Chemistry learners along posttest exceeded the 75% mastery level prescribed by the DepEd. There is a significant difference between the level of performance of grade 7 learners in the pre and post-test results in General Chemistry during the school year 2021-2022. The computed value is greater than the tabulated value, therefore the null hypothesis is rejected. On the evaluation of the learning modules, the learners encountered learning difficulties by obtaining low mastery in four of the competencies in General Chemistry which were the bases in implementing the developed modules. The learning modules were rated “Very Satisfactory” by the expert- evaluators. The modules are effective for use of General Chemistry learners. Thus, the learning modules in General Chemistry should be recommended for use by the learners in the school not only in the three courses but all learners taking up General Chemistry. Also, teachers in other areas of discipline should also develop other forms of instructional materials and recommend them for validation for successful teaching-learning outcomes.
