Addressing chemical reaction misconceptions using five phase Needham Model

摘要

This study aims to assess and address the misconceptions that exist in the chemical reactions topic among Malaysian form five students. The study uses Five Phases Needham Model that applies in the multimedia software to overcome the misconceptions that exist in this area of chemical reaction in the classroom instruction. The study also used ADDIE Model (Analysis, Design, Development, Implementation and Evaluation) to develop multimedia software. Thirty secondary school students and thirty Chemistry teachers took part in this quantitative study which uses the experimental and survey methods. A pre-test and post-test were used to assess the effectiveness of the software in overcoming students misconceptions in the area of chemical reactions. In addition, the study also collects data from teachers through a questionnaire to test the suitability of this software. Data of pre and post tests and questionnaires were analyzed using descriptive statistic. The results showed that this multimedia software is effective to be practiced in schools among students. The survey also reveals that the software is suitable from various aspects such as understanding of learning content, navigation of software and increase of intrinsic motivation of students. Besides, this study also benefits from the perspective of providing information about the compatibility of multimedia software in Chemistry Education. In fact, secondary school teachers can use this study and the software as a reference or guide for deploying multimedia in teaching and learning.
