Development of Context-Based Teaching Book on Environmental Pollution Materials to Improve Critical Thinking Skills

Abstract

This study aims to develop a teaching book based on context to improve students' critical thinking skills on environmental pollution materials. The research method used in this study was Research and Development (R & D) with ADDIE design (Analysis, Design, Development, Implementation, and Evaluation). The instruments used in this study consisted of expert validation sheets which were used to validate teaching materials by experts, questions about readability of teaching books, questionnaires to determine students' and teachers' responses to teaching book, and instruments of critical thinking skills. The results showed that teaching books had a good level of validation in aspects of content, presentation, and language, students' responses to teaching books were very good, the teaching book assisted teachers in the learning process, and improve students 'critical thinking skills on environmental pollutions after using teaching book with N-gain of 0.33 (moderate). This indicates that context-based teaching book is useful for developing students' critical thinking skills on environmental pollution material.

Enhancement of Student’s Critical Thinking Skill through Science Context-based Inquiry Learning

“…Those teaching materials have been assessed professionally with the average result of the assessment is 85%, and readability test on environmental pollution and the impact of environmental pollution are 63.7% and 62.5%. (Pursitasari et al, 2019). This means that teaching material with science context have been validated and can be understood by students, but still requires teacher guidance through the learning process.…”

Is Awareness on Plastic Pollution Being Raised in Schools? Understanding Perceptions of Primary and Secondary School Educators

“…Hay and Thomas [40] highlighted that posters make sense as a means of communicating scientific investigation results quickly and effectively and also as an important teaching and learning aid. Pursitasari et al [41] observed that students' responses improved when provided with a strong validation through content, presentation, and language via books and posters, which also assisted educators in the learning process, and improved students' critical thinking skills on environmental pollutions.…”

“…Resources allocated towards environmental education in the sampled schools include textbooks, dustbins and posters. Environmental protection education textbooks and posters have been highlighted to play a significant role in students' pro-environmental behavior [41]. Dustbins are the most utilized resource allocated in every sampled school as they educate learners regarding where to throw litter, thus making the immediate environment look tidy.…”

Development of Motion-Theme Teaching Materials for Science Learning in Junior High School

“…The development of science teaching materials has been carried out with the theme of pressure in everyday life [6], air [7], and environmental pollution [8]. In addition, the development of teaching materials based on scientific literacy and Chemirel igiousa teaching materials has also been carried out [9,10].…”

“…In addition, the development of teaching materials based on scientific literacy and Chemirel igiousa teaching materials has also been carried out [9,10]. The development of teaching materials are able to increase digital literacy [7], scientific literacy [8,9], and character and learning outcomes [10]. However, there was no teaching material on the theme of motion.…”
