Boosting Test Scores of Grade 10 Students in Electromagnetism through Collaborative Testing

Abstract

INTRODUCTION

Most high school students have a strong untoward perception about physics as a subject due to its highly cognitive, abstract, and mathematical nature. Because of these aspects, the achievement, in the form of test scores, of students in physics is generally low as reflected by multiple researches done nationally and abroad. This study entitled "Boosting Test Scores of Grade 10 Students in Electromagnetism through Collaborative Testing (CT)" aims to investigate the effect of Collaborative Testing (CT) to the scores of Grade 10 students in electromagnetism topic.

METHODS

This study utilized non-equivalent pretest-posttest experimental research since its main purpose was to determine the effectiveness of collaborative testing in enhancing the test scores of the Grade 10 students in electromagnetism. The study used pretest and posttest as instruments to collect the performance of the students on electromagnetic induction. The tests were composed 12 multiple choice items and 3 problem solving items. Additionally, the test used for intervention were composed of open-ended questions and problem solving to allow collaboration among the students. All teacher-made tests were validated by 3 physics teachers in terms of content and construction. The participants of this study were the 45 Grade 10 students. The participants were grouped into two using a toss coin method; the two groups were assigned as experimental and control.

RESULTS

Results revealed that the pre-test scores of the control and the experimental group do not differ significantly. The post-test scores of the groups significantly differ resulting to higher scores for the experimental group. Significant differences exist in the pre-test and post-test scores of the control group and experimental group. There is an improvement in the groupings of pupils both in the control and experimental group, but significant improvement was shown for the students exposed under Collaborative Testing. Therefore, the use of Collaborative Testing is effective considering the higher scores of the experimental group compared to the control group.

DISCUSSIONS

Based on the outcome of the research, the researcher recommended that Collaborative Testing is an effective method in boosting the test scores of students in electromagnetism. It can be concluded that collaborative learning fosters the development of academic confidence, creativity, and emotional intelligent through exchange of views, elucidation of thoughts, and analysis of views of others.
