ABSTRACT
This study was conducted to test the effectiveness of Color-Coded Mnemonics (CoDeCs) in teaching chemical nomenclature among Grade 11 STEM students at Luna National High School for the school year 2018-2019. Quasi-experimental pre-test post-test research design was utilized consisting of 22 students of STEM Mendeleev as control group and 20 students of STEM Einstein as experimental group. Total enumeration was utilized. Color-Coded Mnemonics was employed in the experimental group while lecture method in the control group. Statistical tools such as mean and standard deviation were used to determine the mean pre-test and post-test scores of the two groups before and after the implementation of CoDeCs, paired and independent means t-tests were used to analyze the difference on the test scores between and among the two groups before and after the implementation of CoDeCs, and Eta2 was used to analyze the effect size of CoDeCs in the achievement of the students. Results showed that the achievement in chemical nomenclature of the experimental group was outstanding compared to the control group which was very satisfactory. Moreover, there was a significant difference in the mean difference on the pre-test and post-test scores of the two groups, the experimental group performed better than the control group. Paired differences on the scores of the experimental group showed significant over the control group. It further revealed that the use of CoDeCs (Color-Coded Mnemonics) had a large effect on the achievement of the students in chemical nomenclature and had a small effect on the magnitude of the difference between the scores of the control and experimental groups. This implied that the use of CoDeCs is an effective intervention material in improving the academic achievement of students on chemical nomenclature and is therefore highly recommended for use by other teachers in different learning areas and grade levels.
