Developing an E-student Worksheet Using Phenomenon-based Learning for Reaction Rate Material on Wizer.me for Class XI High School/MA

Abstract

The aim of this research is to develop an E-Student Worksheet based on Phenomenon-Based Learning on Reaction Rate Material Using the Wizer.me website for Class XI Highschool/MA. The development of this E-Student worksheet was carried out because teachers have not used digital learning media and used the Phenomenon-based Learning model in their learning, especially in reaction rate materials. The Phenomenon-Based Learning approach is particularly significant for reaction rate materials because it can increase student engagement because learning is centered on real phenomena that are relevant to their lives. This development research uses the 4-D model, which consists of define, design, develop, and disseminate. However, this study was limited to the development stage. Data was collected through questionnaires, and interviews. Data analysis was carried out quantitatively, and qualitatively, guided by ideal evaluation criteria to determine the quality of the E-student worksheet. The research results show that the E-Student Worksheet that has been developed were declared valid in material validation in terms of content eligibility, characteristics of Phenomenon-Based Learning, language, presentation and graphics were 97.5%, 100%, 95%, 100% and 100% respectively. The results of media validation in terms of E-Student Worksheet display and software usage are 100% and 100%. The results of the user response test obtained a percentage score of 92.41% by chemistry teachers with very good criteria and 89.51% by students with very good criteria, which indicates that this E-student worksheet is valid and suitable for use as an alternative teaching material in the learning process, and it is hoped that this research can be continued in the next stage.
