This study aimed to develop, validate and determine the level of acceptability of Science and Technology modules which served as supplementary instructional material for the students. This study was conducted during the School Year 2013-2014 at San Jose National High School. Specifically, the study sought to answer the questions on the mean scores of the student-respondents in pretest and posttest in terms of the following covered topics in modules: Motion, Wave, Sound, Light, Heat and Electricity and if there is significant difference between the mean scores of the tests. The level of acceptability of the modules as perceived by the Science Teachers in terms of Objectives, Contents, Activities, Organization, Creativity, Style and Presentation and Evaluation was also determined. The study made use of experimental method utilizing single group pretest-posttest design and descriptive method utilizing evaluative design. The respondents of the study were composed of six (6) Science Teachers and thirty (30) Grade 7 students from San Jose National High School and two (5) Science Professors from University of Rizal System-Rodriguez.
The instruments used in the study were the 60-item teacher made test in the 6 topics to validate the modules and a questionnaire checklist to evaluate the modules. On the validity of the modules and test, content validity was used with the help of experts who criticized the module. Then, test made use of table of specification. Pilot testing came after and it undergo item analysis and reliability test with the result of 0.76, using split-half test it determine the correlation of the test. The pretest and posttest was conducted to validate the modules. After gathering the scores of pretest and posttest, the application of appropriate statistical treatment and analysis and interpretation of data were used. On the mean scores of the student-respondents in the pretest and posttest of 6 topics, it was shown that the mean score increased from 33.07 in the pretest to 41.67 in the posttest. On the significant difference between the mean scores, the p-value 0.000 is less than 0.05 level of significance; therefore, the null hypothesis is rejected.
On the acceptability of Science and Technology modules as evaluated from the adapted questionnaire checklist of the faculty-respondents, with respect to objectives it has a weighted mean of 4.63, content has weighted mean of 4.42, activities has weighted mean of 4.91, organization has weighted mean of 4.48, creativity has weighted mean of 4.44, style and presentation has weighted mean of 4.46 and evaluation has weighted mean of 4.37, with an average weighted mean of 4.53.
Based on the findings, the following conclusions were summarized: The utilization of the developed modules among the student-respondents, improved their performance in posttest and the teacher-respondents evaluated the modules as very acceptable, thereby saying that the modules can be used as supplementary instructional materials for Science and Technology 7.
Based on the findings and conclusions of the study, the researchers recommended the instructional materials to use for the benefits of the students, teachers, parents, curriculum planners and ALS students as well. for 4.44, style and presentation has weighted mean of 4.46 and evaluation has weighted mean of 4.37, with an average weighted mean of 4.53.
