Development of online student worksheet based on scientific approach to improve critical thinking ability in Junior High School

Abstract

This research is based on learning activities in several junior high schools in Tangerang that have yet to be oriented to students' integration and critical thinking skills. The ability to think critically in learning can be done by growing it through electronic teaching materials like an electronic worksheet with a scientific approach. STUDENT WORKSHEET is compiled using a flip pdf builder application to support learning in the 21st century by utilizing technology. The purpose of this study was to design student worksheets in electronic form with a scientific approach to the theme of the role of biotechnology in food diversification to foster the critical thinking skills of class IX students. The research method used is Research and Development (R&D) development research with Thiagarajan development design through modifications that are tailored to the needs of researchers with being limited to the expert validation stage, which includes the following stages: Definition ( Define), Design ( Design ), Development ( Develop ). The instrument used is a material expert validation questionnaire sheet, media expert, and science teacher. The results of this study indicate the validity of the student worksheet by obtaining an average percentage value of 79.92% with a valid category which includes material experts at 63.7% with a valid category, teaching media experts at 81.96% with very valid categories, and teachers IPA is 94.11% with a very valid category.

Development of electronic worksheets based on project-based learning assisted by a virtual laboratory to train students' critical thinking skills

“…This research aimed to describe the validity, practicality, and efficacy of electronic worksheets in training critical thinking. Electronic worksheets are student worksheets that can be processed digitally, systematically, and continuously within a period [21]. Electronic worksheets developed is a student worksheet that is done with the help of a simulation of reaction rate practicum in the Crocodile Chemistry 605 application.…”

Implementation of Worksheets Based on Experiments on The Subject of Biotechnology to Develop Students' Scientific Literacy

“…Recent studies underscore the importance of integrating advanced methodologies in LKPD design to foster scientific literacy, especially in burgeoning fields like biotechnology. (Nirmala et al, 2021;Wulan et al, 2023) emphasized the need for electronic student worksheets incorporating scientific approaches to enhance critical thinking in biotechnology, while (Arifah et al, 2022) showcased the benefits of ethnoscience and STEM-based worksheets in boosting literacy and character development. Moreover, delineations by (Dewantara et al, 2019;M.…”
