In order for the student to achieve of one unit of content before moving on to another then the modular instruction has been introduced to individualize learning. This study aimed to develop and validate the inquiry-based learning activity sheets in Life Science for Grade 11 in HUMMS at Bulan National High School for school year 2021-2022. It used the developmental method of research. The respondents were the 25 Grade 11 HUMMS students in Bulan National High School which were purposively chosen and 5 experts teaching in science. 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 for use in the home learning environment is appropriate and commendable. Also, the developed inquiry-based learning activity sheets are very evident that standards are followed and applied the appropriate pedagogies for the learning area as evaluated by the experts. Similarly, the developed inquiry-based Learning Activities Sheets in Life Science showed significant difference on the performance of the students as revealed in the pre-test and posttest results in terms of lessons in History and Development of the concept of life, Unifying themes, Animal Reproduction, Process of genetic engineering, and Benefits and Risks of using GMO.
It was recommended that the developed inquiry-based learning activity sheets in Life Science can be used to improve the retention and mastery of the lesson of the Grade 11 HUMMS students. The constant modification and revision on the developed learning activities sheets may be done to conform to the learning abilities, style and habits of the students. Test the effectiveness of the developed Learning Activities Sheets for Grade 11 HUMMS Life Science to the fast learners and other type of students identical to multiple intelligence. Future research on the creation of another instrument or collection of worksheets is encourage to reinforced in teaching various fields of science and across different disciplines at different grade levels.
