Abstract:
The study focused on the usefulness of Modified Strategic InterventionrnMaterials (MSIM) in enhancing the learning skills of the Grade Five Pupils in Science.rnThe researcher developed a Teacher-Made Test used for the pretest and posttest design.rnThe test was validated by five teachers and twenty five grade V pupils who are not partrnof the study and revise some parts of the test based from suggestions. The researcherrnadministered the instrument at Mangin-Tebeng Elementary School among the identifiedrnexperimental and control group. The study is applying quasi-experimental method usingrnone-shot experimental design. Quasi-experimental method is concern on the internalrnvalidity, because the treatment and control groups may not be comparable at baseline.rnWith random assignment, study participants have the same chance of being assigned tornthe intervention group or the comparison group. The researcher found it appropriate forrnthe study since the study used to estimate the causal impact of an intervention on itsrntarget population; hence, the quasi-experimental method was used. All data gatheredrnwere used for academic purposes and enhancement of instructional materials used inrnteaching Grade V pupils in Science. The statistical tool used in determining thernachievement of the experimental and control group in the post-test results is the studentrnT-Test for independent sample, this type of t-test is used when comparing means of twornindependent groups. The researcher used the statistical packages for social sciencesrn(SPSS 14.0) for the tabulation of the result and manual computation to counter checkrnthe result.The findings indicated a tremendous increase from the result of pretest to thernpost test. Therefore, the modified strategic intervention materials were effective inrnmastering the competency based–skills in Science based on the mean gain scores in thernposttests of the experimental and control groups
