PROBLEM-BASED LEARNING AND ITS EFFECTS ON ACHIEVEMENT AND ATTITUDE IN SCIENCE AMONG GRADE 8 STUDENTS.

The study used quasi-experimental research design to investigate the effects of problem-based learning (PBL) on the attitude and achievement in science among Grade 8 students in a public high school in the Philippines. A problem-based learning module was developed using the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. It was used in teaching science. On the other hand, the Attitude Questionnaire in Science was adopted to describe the attitudes of students in both the control and experimental groups. Data were analysed through descriptive statistics. Prior to teaching science using PBL, the students showed different attitudes and had a low achievement in terms of mean percentage score. But after the implementation of PBL instruction, the students got positive attitude in science. They find the experience interesting and challenging at the same time. The PBL instruction in the experimental group caused a better understanding of topics in science than the lecture-based instruction. Given the results, the study recommended specific teaching techniques that will be useful in applying PBL to develop the students' attitude and achievement in science especially in a blended-learning setup in this new normal.
