Development and Validation of Inquiry-Based Learning Activity Sheets in Physical Science

This study aimed to develop and validate the inquiry-based learning activity sheets in Physical Science for Grade 11 ABM at Gubat National High School for the school year 2022-2023. It used the developmental method of research. The respondents were the thirty (30) Grade 11 ABM students in Gubat National High School who were randomly chosen and five (5) experts teaching in science who were purposively chosen. The statistical tools utilized were the weighted mean, frequency, and t-test for dependent samples.

The study revealed that the developed inquiry-based learning activity sheets were successful in teaching basic Science concepts as supplementary instructional materials. Experts firmly agreed that the instructional content of the said material is commendable. Moreover, the developed inquiry-based learning activity sheets clearly demonstrate that standards are adhered to and used in conjunction with the proper pedagogies for the subject matter as determined by the experts. As revealed in the pretest and posttest results in terms of lessons in Aristotelian vs Galilean views of motion, freefall, graphing motion, acceleration, and Newton’s laws of motion, the developed learning activity sheets are effective in improving the performance of Grade 11 students in physical science.

It was recommended that the developed inquiry-based learning activity sheets in Physical Science be used to improve the retention and mastery of the lessons of the Grade 11 ABM students and of other academic strands and TVL strands. It was recommended that the developed LAS may be subjected to validation using other criteria and be tested for acceptability. It was also recommended that the effectiveness of the developed learning activity sheets be tested using a robust experimental design. Future research on the development of other instructional materials is encouraged to reinforce teaching various fields in science and across learning areas at different grade levels.
