One of the goals of mathematics education in the Kurikulum Merdeka is to develop students' creative thinking skills in mathematics. However, current evidence shows that students' creative thinking skills remain low. This issue arises because students are not regularly exposed to contextual problems that require creativity, argumentation, and reasoning. Moreover, the use of Student Worksheets is still limited and does not adequately foster students' mathematical creative thinking skills. In response, this research aims to develop a Student Worksheet based on the Problem Posing and Solving Learning Model, commonly known as the Jucama model, focused on the Pythagorean theorem content to enhance the mathematical creative thinking skills of phase D students. The research follows a development approach using the 4D model, which includes the stages of define, design, develop, and disseminate. Data were collected using questionnaires, involving 15 ninth-grade students from SMP 22 Pekanbaru in a small group trial. The validity of the worksheet, as evaluated by experts, averaged 92.5%, categorizing it as very valid. The practicality of the worksheet was rated at 83.33%, also categorized as very practical. These results indicate that the worksheet developed using the Jucama model on the Pythagorean theorem content is both valid and practical for facilitating the creative thinking skills of phase D students.

SSI learning was conducted in the classroom and designed to cultivate characteristics and attitude of SSI. The integration of SSI with the learning process involved instruction that inquiry analyzing based on environmental issues. A total seventy-six chemistry education majors participated in the study, including eleven male and sixty-five female students. Data were collected through a structured questionnaire that measured the participants’ characteristics, civic value, and attitude of SSIs. The collected data were analyzed using SPSS 26 with, employing descriptive statistic and Mann-Whitney U analysis. The result revealed that male pre-service chemistry teacher group has a higher score in character, value as citizens, and attitude of SSI compared to their female counterparts. However, the analysis showed no statistically significant difference (p>.05) between male and female pre-service chemistry teacher in the sub-factors of character and SSI attitudes. Despite the lack of significant gender differences, the findings suggest that the integration of SSI in chemistry education can enhance moral thinking and decision-making abilities and positive attitude toward SSI. Teachers may consider both subject matter and instructional method when addressing these aspects in the classroom.
