INTRODUCTION
Learners are the center of the teaching- learning process though they have different ways on how to perceive learning. At present, most of them are visual learners as they learn more if they see things that are appealing to their eyes.This study was conducted to assess the applicability and effectiveness of using the developed Intervention Material (learning package) in Biology among Grade 9 students for the topic Human Cardiovascular System. This concept for the first grading period is the topic that includes several medical and technical terms or in short unfamiliar words.
METHODS
In the conduct of this study, the t- test was used wherein the scores of the given pre- test and post test were compared between the three (3) sections (experimental group) and one (1) section (controlled group). The experimental groups were tasked to use the developed Intervention Material while the other section (controlled group) still use the traditional learners’ module. The results were tested whether there is a significant difference between the scores of students who used the Intervention Materials and those who did not. Interpretation of the results was done.
RESULTS
All students who used the developed Intervention Material showed an improvement with regards to their scores while it was found out that the students who did not use the IM showed no changes on their scores in the post test. This improvement was due to the following reasons 1) students’ interest was caught because of the colorful and appealing pictures found in the Intervention Material for they really are proven to be visual learners, 2) the inclusion of the activities per subject was found to be helpful to attain retention of the topics learned and 3) provision of the copy of the developed Intervention Material for every students during Science time.
DISCUSSION
The results of this study showed that the developed Intervention Material is proven to be effective. Teachers’ creativity and patience are now being encourage to come up or somehow develop or make their own Intervention Material. Though extra time and effort is required to come up with one. Learners learn more if they see things with their own eyes. They are the center of the teaching-learning process where in our main target is to make them learn.
