High self-confidence and creative mathematical thinking skills will change students from having difficulty with mathematics to active learners who can solve mathematical problems. But the facts show that the achievement of both abilities is still quite low. The purpose of this research is to analyze how students' creative mathematical thinking skills are viewed from the perspective of self-confidence in social arithmetic material. Social arithmetic material is used because it allows them to abstract mathematical processes into their daily lives, thereby developing their creativity. The research method is descriptive qualitative. The sample was 3 people, namely 1 person for each level of self-confidence (high, medium, and low). They are selected through purposive sampling. The data collection techniques used include questionnaires, tests, interviews, and field notes. The data analysis techniques employed are data reduction, data presentation, and conclusion drawing. The results indicate that students' self-confidence levels in social arithmetic material affect their creative mathematical thinking skills. It was found that students with high self-confidence were able to meet three indicators of creative mathematical thinking skills: fluency, flexibility, and elaboration. However, students with high self-confidence were not able to meet the originality indicator. Students with moderate self-confidence were able to meet one indicator of creative mathematical thinking skills, namely fluency, but were not able to meet the flexibility and elaboration indicators. Meanwhile, students with low self-confidence were not able to meet any indicators of creative mathematical thinking skills. Thus, self-confidence can be increased to improve mathematical creative thinking skills.

Quantitative data were analyzed descriptively inferentially using paired sample t test. The results showed a difference in the average problem-solving skills and creative thinking skills before and after PBL was applied, so this study proves that the application of PBL can improve students' problem-solving skills and creative thinking skills in Biology learning.

The ability to think creatively in mathematics is a crucial aspect of learning, yet evidence shows that students' creative mathematical thinking skills, particularly in the topic of Sequences and Series, remain low. One solution to address this issue is through the use of Problem-Based Learning (PBL)-based Student Worksheets. This research aims to develop a valid and practical Student Worksheet. The study follows the 4D development model, consisting of the stages: define, design, develop, and disseminate. The instruments used for data collection were validation sheets and practicality questionnaires. Analysis of the validation sheet data showed that the Student Worksheet was categorized as highly valid, with an average percentage of 93.73%. Similarly, the practicality questionnaire analysis indicated that the Student Worksheet was rated as practical, with an average percentage of 83.77%. Therefore, the developed Student Worksheet meets the criteria of validity and practicality and can be used effectively in learning activities. The implication of this research is that it allows students to independently build knowledge in mathematics, facilitating their creative mathematical thinking skills.

This study aims to identify students’ creative thinking skills in solving the problem of using chitosan as a natural preservative in processed meat. This research uses mixed methods, namely a combination of quantitative and qualitative research methods. We used quantitative research methods to analyze the results of student’s creative thinking skills in the application of RBL-STEM, while qualitative research methods were used to analyze the learning activities and portrait phases of students’ creative thinking skills. The research respondents consisted of two classes, namely the control class and the experimental class. The control class has 25 students, and the experimental class has 30 students. We used tests, interviews, and questionnaires to collect data in this study. The results showed that the independent sample t-test on the post-test scores of the control class and the experimental class showed significant differences. This is due to the value of sig (2-tailed) is 0.000 (p=<0.05). It can be concluded that the application of the RBL learning model with the STEM approach can improve students' creative thinking skills in solving the problem of using chitosan as a natural preservative for processed meat.

Critical thinking and creative thinking skills are needed to improve the quality and competitive human resources. Therefore, the application of appropriate learning models is expected to stimulate students' critical thinking and creative thinking skills. This research aims to improve critical thinking and creative thinking skill scores using the ASICC learning model. This type of research is classroom action research which is carried out in 2 cycles, with 3 meetings in each cycle. Data on students' critical thinking and creative thinking skills were collected using essay tests on science learning materials. Data analysis was carried out by comparing the N-gain scores in cycle 1 and cycle 2 for students' critical thinking and creative thinking skills. The results of the research revealed that there was an increase that occurred in cycle 2, namely 5.6% in the aspects of moderate critical thinking skills and high creative thinking, as well as in the aspects of critical thinking skills and high creative thinking by 5.6%. Meanwhile, in the previous cycle, these two aspects did not have a high category. Another result found from this research is that students who have low critical thinking skills do not necessarily have low creative thinking skills. This is because students who have low critical thinking skills may have moderate creative thinking skills or vice versa. Thus, the application of the ASICC learning model is effective in improving the scores of critical thinking skills and creative thinking skills of students at Junior High School 5 Kertosono.
