Thematic Module Based on Groundwater Quality to Enhance Creative Thinking Abilities and Student Perceptions

Abstract

This study aims to (1) describe groundwater quality in terms of physical and chemical parameters; (2) Describe the improvement of the ability to think creatively using thematic modules on the impact of pollution on life; and (3) Describe the increase in students' perceptions of the importance of caring for the environment using the thematic modules on the material impacts of pollution on life. The type of research used is the Research and Development (R&D) development model of ADDIE (Analysis, design, development, implementation and evaluation). The analysis phase is carried out on ground water quality using 7 parameters, namely temperature, pH, dissolved oxygen levels, salinity, TDS, turbidity and Electrical Conductivity. The results of the analysis are packaged in a thematic module on the impact of pollution on life for class VII SMP / MTs to improve students' creative thinking abilities and perceptions of caring for the environment. The sample of the study was SMPN 18 Bengkulu Tengah students, for a limited scale there were 10 students of class VIII, while the broad scale were 21 students of class VII. Data analysis was performed using the N-Gain test. On a limited scale the results of the gain of creative thinking ability is 0.784 (high) with effective criteria and the gain of environmental care is 0.566 (moderate) with quite effective criteria. Whereas in the wide-scale test, the result of creative thinking ability gain was 0.66 (moderate) with quite effective criteria and the gain of environmental care was 0.562 (moderate) with quite effective criteria. Based on the analysis of the N-gain test it can be concluded that the thematic module of the impact of pollution on life can improve the ability to think creatively and students' perceptions of the importance of caring for the environment.
