COLLABORATIVE INQUIRY APPROACHES AND LEVEL OF THINKING AND REASONING SKILLS: BASIS FOR SUSTAINABLE SCIENCE EDUCATION

The study was conducted to investigate the effectiveness of collaborative inquiry approaches such as problem-based learning and project-based learning on improving the thinking and reasoning skills of students. Furthermore, it aimed to determine the difference in pretest and posttest scores, and correlate the students' perceived effectiveness on the approaches' process, implementation and outcomes to the mean posttest scores. Descriptive-comparative research design was used. Sixty Grade 10 students clustered into two groups were selected as respondents in San Pablo City Science Integrated High School during the academic year 2018-2019. Survey questionnaires and pretest-posttest questions were utilized to obtain the data. Results revealed that there was a significant relationship between the students' perceived effectiveness of collaborative inquiry approaches and their mean posttest scores in thinking and reasonings skills. However, the results of the pretest and posttest of the students were significantly different. On the other hand, there was no significant difference between the students' mean posttest scores exposed to problem-based learning and project-based learning. Both learning approaches can co-exist inside the classroom as effective modes of teaching real-world learning and building future-ready skills.
