Abstract

The research on the development of this textbook was carried out based on the results of the analysis of student needs, namely that there are no teaching materials that can improve students' science process skills in the Tissue Culture course at the Department of Biology, State University of Medan. This textbook is compiled based on the learning syntax of Project-Based Learning (PjBL). This study aims to develop a Project-Based Learning-based tissue culture textbook to improve students' science process skills. This research method uses the Research and Development (R&D) with Thiagarajan's 4D (Define, Design, Develop, and Disseminate). The population of this study was students of the Biology Department of Universitas Negeri Medan with a sample of 47 people who were given a PjBL-based tissue culture textbook. The results showed that (1) the textbooks have been tested for feasibility by material experts (87,73) (2) instructional design experts (92) with a very feasible category, (3) the response of tissue culture lecturers (92) and (4) students based on individual tests (95.1), small group tests (93,75), and limited group tests (90.02) with a very good category and (5) the results of the calculation of N-Gain for science process skills were obtained at 0.66 which is in the medium category.

Abstract

Science learning in the 21st century or the technological century, requires teachers to have teaching skills by utilizing technology. Learning carried out in Indonesia is still less encouraging for the achievement of critical thinking skills of students. The study aims to determine the Effect of the Guided Inquiry Learning Model based on PhET Media on the Critical Thinking Skills of Junior High School Students on Vibration and Wave Material. The type of research used is a quasi-experiment with Pretest and Posttest Control Group Design. The population in the study were all students of class VIII UPT SMP Negeri 27 Medan totaling 317 students. The research sample was taken using probability sampling techniques, namely VIII-3 as the experimental class and VIII-2 as the control class, each class consisting of 30 students. The instrument used was multiple choice consisting of 20 validated questions. The data analysis technique used normality test, homogeneity test, hypothesis test and n-gain test. The results of the study were obtained from hypothesis testing using the Independent T-Test 2-Tailed test obtained Sig. (2-tailed) of 0.000. The Independent T-Test 2-Tailed test result data states that there is a difference in the average value of the two classes. The N-gain test in the experimental class obtained a result of 0.74 with a high category, so it can be concluded that the application of the guided inquiry learning model based on PhET media has an influence on improving students' critical thinking skills on vibration and wave material in class VIII UPT SMP Negeri 27 Medan. The research is useful as information material for teachers, as alternative material for selecting learning models and as a reference for researchers to study the same research.
