- 2. MEAN PERCENTAGE SCORE The mean percentile score of the Science rating obtained by students in the National Achievement Test of the School Year 2009 – 2010 was noted and used for description. It was categorized according to Mastery Descriptive Equivalent into the following (NETRC,2010): Mastered (M) -96% - 100% Close to Approximating Mastery (CAM) -86% - 95% Moving Towards Mastery (MTM) -66% - 85% Average Mastery (AM) -35% - 65% Low Mastery (LM) -15% - 34% Very Low Mastery (VLM) -5%- 14% Absolutely No Mastery (ANM) -0% - 4%

- 25. SUMMARY The strategic intervention materials are effective in mastering the competency based – skills in chemistry based on the mean gain scores in the posttests of the experimental and control groups.
- 26. Intervention materials contributed to better learning of the concepts among students. Posttests and maintenance tests indicated that students who were taught with material employing the causal style of discourse had significantly better retention of facts and concepts and were superior in applying this knowledge in problem- solving exercises.
- 27. CONCLUSION In the light of the findings, the following conclusions were drawn: The two groups of respondents had the same level of Mental Ability before the treatments. The experimental and control groups performed at the same level before the experiment. The experimental group performed better in the posttest than the control group. The strategic Intervention materials were effective in teaching competency-based skills. There was significant difference between the mean scores in the posttests of the experimental and control groups.
- 28. RECOMMENDATIONS Based on the outcomes and implications of the study, the following are recommended: Chemistry teachers can use the strategic intervention materials made by the researcher to re-teach the concepts and skills and help the students master the competency- based skill. Seminars and in-service training should be conducted in the division level regarding development and implementation of the strategic intervention materials in the classroom. Chemistry teachers should develop more strategic intervention materials for the remaining lessons which were not included in researcher’s SIMS. Strategic intervention materials for other subjects should be made to address the least mastered skills. A similar study may be conducted covering a bigger number of respondents in another venue.
