New Perspectives in Science Education

This study was designed to evaluate the effectiveness of using instructional media as a technique  in  improving  the  science performance of sophomore students of The National Teachers College.

The  experimental  method  of  study  specifically  the  Pretest - Posttest  Pattern  Design  by  Campbell  and  Stanley  was  used  to determine  the  significance  of  integrating  instructional  media  in everyday lessons of  Science and  Technology II.   The subjects were grouped into two, the experimental and the control group, properly selected and equated based upon their age, gender and mental ability. After equating, pretest was administered to the two groups.

Although  both  dealt  with  the  same  subject  matter, references  and  objectives  of  the  lesson,  the  control  group  was restricted  only  in  grasping  basic  science  concepts  through  the utilization of conventional or traditional method of teaching.  On the other  hand,  the  experimental  group  was  exposed  to  various instructional media teaching aids such as educational video, overhead projector,  LCD,  carousel  or  slide  projector  and  even  electronic encyclopedia,  online  activities  and  quizzes  directly  from  computer. After consuming the allotted time and covering the entire lesson to be discussed, both groups underwent final evaluation through the posttest.  The results were compared to assess the goal of the study.

It  was  revealed  that  the  exposure  of  the  students  to  various instructional materials contributed to the conclusion that there was a significant  change  in  the  performance  of  the  experimental  group compared with the control group.
