Learners’ Mastery of Competencies in Chemical Reaction

This study aimed to determine the learners’ level of conceptual understanding in chemical reaction. Particularly, this study covered topics in chemical reactions such as balancing chemical equation, type of reaction, examples of chemical reaction, and conservation of mass. Descriptive statistics such as the mean and standard deviation was employed to determine the real-life status of learners in terms of their mastery in chemical reaction. Moreover, the results revealed that 100% of the learners did not meet expectations leading to “failed†remarks. The mean score of 13.5 and a standard deviation of 3.759 further indicate the low performances of learners. The study revealed that Balancing Chemical Equation is the least mastered competency of the grade 11 learners with mean percentage score of 20.15, followed by the Type of Reaction with mean percentage score of 21.35, Examples of Chemical reaction with MPS of 25.86, and the Conservation of Mass with an MPS of 40.29 having the highest mean percentage score and the only one to have an average mastery among other topics. Based on the results, the researcher recommends benchmarking this study in developing effective chemistry instructional materials that could enhance learners’ conceptual understanding in balancing chemical equation.
