Abstract

This study aimed to describe the feasibility of teaching modules with mind mapping strategies to improve creative thinking skills in chemical bonding material. The research method used was the 4-D model (define, design, develop and disseminate) which is limited to the development stage. The trial was conducted on 34 students of class XII IPA 4 at one of state senior high school in Surabaya. The teaching module was said to be feasible in terms of validity, practicality and effectiveness. The results showed the feasibility of teaching modules in terms of content validity getting mode 5 on very good category and construct validity getting mode 4 on good category so that overall the teaching module gets mode ≥4 and is declared valid. The practicality of teaching modules in terms of learning implementation gets a percentage of 93.63%, student activities get a percentage of 97.35% and student responses with a percentage of 92.12% with very practical criteria. The effectiveness of the teaching modules is seen from the improvement of students' creative thinking skills through pretest and posttest mind mapping as well as questions on the description of creative thinking skills on chemical bonding material with an N-Gain value obtained respectively of 0.73 and 0.72 in the high category. Based on the results of validity, practicality and effectiveness can be concluded that teaching modules with mind mapping strategies are appropriate to be used in learning to improve creative thinking skills in chemical bonding material.

Abstract

The purpose of this study was to produce student activity sheets (SAS) of project based learning to improve student’s creative thinking skills. This research used the Research and Development (R&D) method. with a 4D model, which includes the definition stage, design stage, development stage, and dissemination stage, but in this study, it was limited into the development stage. In this study, limited trials were conducted on 34 tenth grade high school students who had previously studied green chemistry material. The feasibility of the student activity sheets was reviewed in terms of validity, practicality, and effectiveness. The validity aspect obtained a mode of 4 with a good category. The practicality aspect, which was observed from the student response questionnaire, student activities, and implementation, obtained percentages of 96,9%, 95,5%, and 100%, respectively. The effectiveness aspect was reviewed from the improvement in students' creative thinking skills, the results of the improvement of creative thinking skills are stated with an average n-gain score of ≥ 0,7 in the high category. These results were also supported by the Wilcoxon test, which obtained a significance of 0,000 < 0,05. Based on its validity, practicality, and effectiveness, the student activity sheets (SAS) developed is suitable for use as a learning media.

Abstract

This study aims to describe the feasibility of teaching modules based on SETS (Science, Environment, Technology, Society) to improve students’ critical thinking skills in green chemistry material. This study uses Thiagarajan’s 4D development research method with modifications from Ibrahim’s 3D method, which includes the define, design, and develop stages. Feasibility was assessed based on three aspects: validity, practicality, and effectiveness. Validity was assessed in terms of content and construct validity. Overall, in terms of content and construct validity, the module received a mode of 3 and 4, which are categorized as good and very good. Furthermore, practicality was reviewed from the student response questionnaire, which obtained an average of 94.81% in the excellent category, supported by the results of student activity observations of 89.04%, which showed active involvement in each stage of learning, and learning implementation of 97.65%, which confirmed that the entire series of activities was carried out very well. Meanwhile, the effectiveness of the teaching module based on SETS (Science, Environment, Technology, Society) can be seen from the increase in the average critical thinking skills test score from 28.72 to 83.86 with an average N-gain of 0.7718, which is in the high category. The Wilcoxon test results showed that all students experienced a significant increase (Z = -5.235; Sig. 0.000 < 0.05). Thus, the teaching module based on SETS was declared effective in improving students’ critical thinking skills in green chemistry material.
