Pengembangan Lembar Kerja Peserta Didik Elektronik (E-LKPD) Berbasis Creative Problem Solving (CPS) Terhadap Kemampuan Berpikir Kreatif Peserta Didik Pada Materi Perubahan Lingkungan
Education is very important for life, as time goes by, the demands on the field of education are getting greater, and accompanied by the rapid development of the world. Teachers are required to be more creative, innovative and able to facilitate students with various teaching materials through technology-based learning to support the demands of the 21st century. In the learning process, there are obstacles faced by teachers and students. These obstacles are one of the factors that cause learning to be less than optimal. One of them is the lack of creative thinking skills of students according to the demands of 21st century learning so that lessons feel meaningless.
The researcher formulated a solution to design innovations through the development of teaching materials, namely e-LKPD based on Creative Problem Solving (CPS) to improve students' creative thinking skills. The main material developed in the e-LKPD is changes in the environment of class X Biology of High School. This research consists of two stages, namely the first stage of developing CPS-based e-LKPD using Research & Development through the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) approach in the Master Program of FKIP UNRI, the second stage of the experiment at SMAN 2 Siak Regency.
The stage of developing the CPS-based e-LKPD validity test involves 3 subjects (material experts, education experts and media experts) assessing the feasibility by experts using a validation sheet. The practicality test stage involved 2 educators of SMAN 2 Siak Regency. Assessment of the practicality of e-LKPD based on CPS learning using questionnaire responses, teacher practicality tests, one-on-one trials and small-scale trials. In the experimental stage to see the influence of CPS-based e-LKPD developed on students' creative thinking skills on environmental change materials. Assessment of students' ability to think creatively using multiple-choice questions pretest and posttest.
The results of the research on the validity test by validators of material experts, education experts, and media experts showed that the CPS-based e-LKPD on the environmental change material that had been developed received a percentage of 3.85 with a very valid category. The results of the assessment in the practicality test show that the CPS-based e-LKPD that has been developed has an average score of 3.8 with a very practical category.The results of the experimental stage research showed that there was a significant influence of the use of CPS-based e-LKPD on students' creative thinking skills, namely in the control class, the average score was 70.8 in the medium category, and the n-gain was 0.5 in the medium category. Meanwhile, in the experimental class, the average score was 81.6 in the high category with an n-gain of 0.7 in the high category.
Based on the results of the development and implementation test of CPS-based e-LKPD products on environmental change materials, it was found that the effectiveness of CPS-based e-LKPD products in the experimental class increased significantly compared to the control class.
