Development and evaluation of an electrochemical teaching: Lectrofun 2.0.

The present study aimed to develop and evaluate a simple and green electrochemistry experimental kit named Lectrofun 2.0. Lectrofun 2.0 consist of educational kits and module which was built using green chemicals, recyclable materials and easily accessible materials. It overview the basic concepts of electrochemistry and electrolysis in the guided learning approach. Objectives of this research are to (1) develop Lectrofun 2.0 module using green chemicals, recyclable materials and easily accessible materials, (2) evaluate the effectiveness of the module in terms of students' understanding of the topic of Electrochemistry and (3) investigate students’ perceptions on Lectrofun 2.0 module. Instructional design model used was based on the Design and Development Research, DDR. The development phase involved the objective of the study (1) while the evaluation phase involved the objective of the study (2) - (3). The research instrument applied content validity assessment form to evaluate the validity of the Lectrofun 2.0 module and pre-post test. The perception questionnaire was used to study the students’ perception of Lectrofun 2.0 in terms of module’s content, format and illustration. Pre-post test was used to evaluate the effectiveness of the module in terms of students' understanding of the topic of Electrochemistry. The findings showed that the content validity index for the Lectrofun 2.0 module and pre-post test were 0.93 and 0.94 respectively. 73.9% students for treatment group showed 4 grades increament (grade E to grade A) after done post-test. Mean construct of content was 3.24 (SD = 0.19), followed by format was 3.61 (SD = 0.18) and illustration was 3.68 (SD = 0.09). The result of this study showed that Lectrofun 2.0 has a significant impact to enhance learners’ comprehension towards topic Electrochemistry and students enjoy learning with this guided experimental kit.
