Abstract

Green chemistry plays a crucial role in minimizing the environmental impact of chemical processes, while science literacy equips students with the knowledge and skills to understand a sustainable future. This study aims to describe the feasibility of a Student Worksheet oriented toward green chemistry using a guided inquiry model, deemed suitable for enhancing students’ scientific literacy skills in the reaction rate topic. The research method employed is the Research and Development (R&D) 4D model, which includes define, design, develop, and disseminate stages, limited in this study to the development stage to analyse needs, design, and test the conformity of the learning media. A limited trial was conducted with 30 eleventh-grade students who had previously received instruction on reaction rate and green chemistry at a senior high school in Nganjuk during the 2024/2025 academic year. Data were collected through questionnaires, observations, and tests, then analyzed quantitatively and descriptively using mode, percentage, Guttman scale, Likert scale, and N-Gain test. The results show that the worksheet is valid in terms of content and construct (mode 4, good category), practical based on student responses (97.5%, very good), student activities (96.86%, very good), and implementation (mode 5, very good). The worksheet was also effective in improving scientific literacy, as evidenced by 90% of students achieving a gain score ≥ 0.7 (high category). N-Gain by indicator: context 0.85, knowledge 0.85, and competence 0.88. Based on its validity, practicality, and effectiveness, the developed worksheet is feasible to use as a learning medium.

Learning outcome at 21st century requires creative thinking skills with students centered learning experience. Project based learning model with mind mapping strategies can be used to encourage activeness and improve creative thinking skills. Supporting learnig media is needed, such as LAPD project based learning with mind mapping strategy. The purpose of this study is to describe the feasibility of LAPD project based learning with a mind mapping strategy to improve creative thinking skills developed in terms of validity, practicality, and effectiveness. The type of research used is Research and Development (R&D) with the 4D model development method. The results of this study indicate that the developed LAPD is valid, with a mode of 4 categories of validity and a mode of 5 categories of high validity. The developed LAPD was deemed practical based on observations of learning implementation, which obtained a mode of 4 and 5, indicating good and very good, respectively. Additionally, through observations of student activities, the average relevant activity was 96.57% and irrelevant activity was 3.43%. Furthermore, through student responses to the learning implementation, 90% were positive, and 93% were positive toward the LAPD. The LAPD was also found to be effective in enhancing creative thinking skills in the green chemistry pretest and posttest and mind mapping test, as evidenced by the paired t-test results for both tests yielding <0.05, and the N-gain values for the mind mapping test at 0.70 and for the green chemistry material at 0.77, both in the very high category. Thus, the developed LAPD is suitable for use in green chemistry learning and capable of enhancing creative thinking skills.

This study aims to determine the feasibility of a Project Based Learning (PjBL) based student activity sheet (SAS) as a learning media on redox reaction material. The feasibility of this SAS is reviewed based on validity, practicality, and effectiveness. The research method used is the research and development model. The product trial design used a one-group pretest posttest. This research was conducted with a total of 29 student in class XI. The research instruments used in this study were SAS validation sheet, student response questionnaire sheet, student activity observation sheet, learning implementation observation sheet, creativity test question sheet, and learning outcome test question sheet. The SAS developed was declared: (1) feasible because it gets a mode score of 4, (2) practical because it gets the results of the student response questionnaire of 97.6%, the results of the observation of student activity and the observation of learning implementation which gets a mode score of 5, (3) effective for training student' creativity because it gets a p-value of 0.000 from the results of the paired sample t-test which shows that the posttest value is higher than the pretest value and there is a significant difference between the pretest and posttest values. The effectiveness of the developed SAS is also supported by the results of the learning outcomes test which get a p-value of 0.000 from the paired sample t-test results which also show that the posttest value is higher than the pretest value and there is a significant difference between the pretest and posttest values. For this reason, PjBL-based SAS on redox reaction material is suitable for use as a learning medium.

Abstract

The demands of 21st-century science education emphasize the development of scientific literacy and sustainability awareness, necessitating the integration of Project-Based Learning and green chemistry–oriented learning materials. This research aims to develop Student Activity Sheets (SAS) based on Project-Based Learning (PBL) to enhance students’ scientific literacy skills related to green chemistry materials. The research method used is Research and Development (R&D) with the 4D model (Define, Design, Develop, Disseminate) limited to the develop stage. The research subjects were 32 grade XI students at MA Unggul Sabira-IIBS Mojokerto. The validity of SAS was assessed by two chemistry lecturers and one chemistry teacher, yielding a validity mode score of 5, indicating very valid criteria. The practicality of SAS was measured through student response questionnaires, obtaining 96.52% (very practical), learning implementation observation with mode 5 (very good), and student activity observation with mode 5 (very good). The effectiveness of SAS was measured through a pretest-posttest of scientific literacy skills with an average N-gain of 0.83 (high category). The results showed that 90% of students experienced significant improvement, with an N-gain of 0.7 or greater. The SAS developed contains three projects: eco-enzyme as organic fertilizer, cloth pads, and natural room fresheners from lime and coffee, all integrated with green chemistry principles and scientific literacy domains. Thus, the SAS based on PjBL is feasible (valid, practical, and effective) for improving students' scientific literacy skills in green chemistry materials.

Abstract

This study was conducted to determine the feasibility of Student Activity Sheets or LAPD designed with a mind mapping strategy to improve students’ creative thinking skills in the topic of chemical equilibrium. The research applied the 4D development model consisting of the define, design, develop, and disseminate stages, but its implementation was limited to the develop stage. The product was tested on 35 eleventh grade students at a public senior high school. The feasibility evaluation covered three aspects, namely validity, practicality, and effectiveness. The results showed that the LAPD fulfilled the validity criteria, as all components of content and construct validity achieved a mode score equal to or greater than 4. Practicality was reflected in the high percentage of relevant student activities at 97.10 percent and positive student responses at 88.54 percent, both categorized as very practical. Effectiveness was indicated by the improvement in students’ creative thinking skills based on the comparison of pretest and posttest results from mind mapping assessments and essay tests, which produced average N gain scores of 0.76 and 0.72, respectively, both classified in the high category. Therefore, the mind mapping based LAPD can be considered feasible and effective in enhancing students’ creative thinking skills in chemical equilibrium learning
