THE RESULT OF PROBLEM-BASED LEARNING WITH GRAPHIC DIAGRAM TECHNIQUES ON ACADEMIC ACHIEVEMENT REGARDING FLOWERING PLANT REPRODUCTION AND THE ABILITY TO THINK CONNECTEDLY OF 5 GRADERS

Abstract

This research aimed to: 1) compare the biology learning achievement of Grade 11 students before and after the learning management; 2) compare their connective thinking ability before and after instruction; and 3) examine students’ satisfaction with the learning management implemented through Problem-based learning integrated with graphic organizer techniques. This study employed a quasi-experimental research design. The sample consisted of 39 Grade 11 students in the second semester of the 2025 academic year, selected by cluster random sampling. The research instruments included: 1) lesson plans for      Biology 3, 2) a connective thinking ability test, 3) a learning achievement test, and                   4) a student satisfaction questionnaire toward the learning activities. Data were analyzed using percentage, mean, standard deviation, and t-test.

          The research findings were as follows:

1. The post-learning achievement scores of Grade 11 students were significantly higher than the pre-learning scores at the .01 level of statistical significance.


2. The connective thinking ability of Grade 11 students who learned through problem-based learning integrated with graphic organizer techniques increased in each action cycle.


3. The students’ satisfaction with the learning management in all aspects was at the highest level.
