Developing a Laboratory Activity by Using 5e Learning Model on Student Learning of Factors Affecting the Reaction Rate and Improving Scientific Process Skills

Abstract

The purpose of this study is to develop a laboratory activity based on 5E learning model enriched with different conceptual change methods such as computer animations, analogy, concept mapping, worksheet and hands-on activities for eliminating prospective science teachers’ (PSTs) alternative conceptions on factors affecting the reaction rate and improving their scientific process skills (SPS). A group of experts was asked to comment on the laboratory activity. Some changes were made based on the comments of experts on the activity. The pilot study of the laboratory activity was carried out with 48 third year PSTs enrolled in ‘Science Laboratory’ course at the Faculty of Education, Giresun University, Turkey. In this paper, all phases of the activity are introduced in detailed. Also, the applicability of activity was investigated in a pilot study, based on observation by an independent researcher. In-class observations showed that the activity is performed two hours and it is effective to improve the students’ motivation and enables them to be active during the learning process. As a result, the laboratory activity can be used as an alternative to activities in the literature. To investigate this and other similar activities’ applicability in a comparative manner, further research should be undertaken. In addition, the effect of the laboratory activity based on 5E learning model combining different conceptual change methods should be examined if it helps the PSTs overcome their alternative conceptions and improve their SPS.
