STRATEGIC INTERVENTION MATERIALS IN CHEMISTRY: DEVELOPMENT AND EFFECTIVENESS Andy L. Soberano Muntinlupa Science High School, Philippines
This study attempted to probe that strategic intervention materials will significantly address the least mastered skills in chemistry. A true experimental research was employed using the pretest-posttest comparison design and samples were determined using the purposive or deliberate sampling technique. Results of the Otis Lennon Mental Ability Test were used to reveal the intelligence of the students and sixty six students with the same school ability index were matched and grouped as the experimental and control groups. The 65 items teacher made test was created and subjected to parallel pilot testing. The items in the test were analyzed and those which were not within the range of 0.20 to 0.80 difficulty index and 0.30 to 0.80 discrimination index were discarded and items fell within the prescribe limit were retained. The validated test was finalized and pilot pretests were administered to two groups of respondents. In addition, the SIM focusing on thirteen least mastered skills were also developed with the help of nine experts. The experimental group was given set of the validated SIM while the control group was exposed to conventional way of teaching. Performance from both groups was constantly monitored and showed that there was no significant difference in the pretests before the intervention and there existed significant difference in the posttests after the intervention. It registered t-value of 8.289 at tabular value 1.67 and degrees of freedom 64 and 0.05 significance level. This suggested that the strategic intervention materials significantly contributed to the mastery of chemistry concepts.
