Optimization of blended learning using ICT-based media for improving learning interest, critical thinking ability, and chemistry learning outcomes

Efforts to optimize chemistry learning outcomes have been carried out through experimental research by implementing blended learning models using ICT-based media for state high school students in the Narmada Zone of West Lombok Regency. This study aims to explore the effectiveness of implementing blended learning in chemistry in high school using ICT-based media to increase students’ interest in learning in chemistry, critical thinking skills, and students. The subjects of the survey consisted of students from SMAN 1 Narmada in West Lombok Regency. The sample was determined by proportional sampling from classes X and XI in the high school concerned. Each experimental class was given a blended learning model using the following media: (1) video and (2) e-student worksheets. Based on the results of research and data analysis, we can conclude that: (1) Implementation of a blended learning model using video media can increase students’ interest in learning chemistry. (2) Implementing a blended learning model using an e-student worksheet can improve learners’ chemical critical thinking skills. Based on the above two conclusions, it is expected that implementing a blended learning model of high school chemistry education using ICT-based media can improve students’ chemistry learning outcomes.
