Abstract

Creative thinking abilities are developed through divergent thinking in mathematics learning. This research aims to explore junior high school students' mathematical creative thinking abilities in solving geometric problems, specifically in terms of their overall mathematical abilities. This study is a qualitative descriptive research project. The subjects were 27 eighth-grade students from a state middle school in Loghia District. Data were collected using tests and interviews. The findings indicate that junior high school students with high mathematical abilities demonstrated creative thinking in solving geometric problems. In contrast, students with moderate and low mathematical abilities showed less creative thinking, particularly when answering questions about surface area and volume. Specifically, there were 3 students identified as creative, 4 students as less creative, and 20 students as not creative. Overall, most junior high school students were not creative in their approach to solving geometric problems. They struggled to demonstrate indicators of creative mathematical thinking, such as fluency, flexibility, and novelty.

Abstract

In Indonesia, the level of students' mathematical problem solving abilities can be said to be lacking due to the teacher's inability to condition a class well. So, to determine which method to use, teachers need to understand their students' abilities first, one of which is through diagnostic assessment. In this research, the researcher aims to find out whether it is possible that through diagnostic tests there is an influence on students' interest in learning on problem solving abilities in class VIII mathematics lessons at SMPN 46 Palembang. The type of research used is quantitative research with a sample of 29 students. The data collected used two techniques, namely questionnaires and also the results of diagnostic assessments. Meanwhile, the analysis used uses a technique which is a simple regression analysis test. Based on the results obtained, it shows that there is a high influence of interest in learning on the results of diagnostic assessments. The results obtained from the learning interest variable which influences the results of the diagnostic assessment in the form of problem solving abilities are results that can be said to be very high. In other words, it can be said that students' interest in learning greatly influences students' problem solving abilities as seen from the results of diagnostic assessments.

Abstract

There is a phenomenon where students with moderate ability can achieve the highest rank in the class, while students with high intelligence often have difficulty or failure in their academic achievement. This suggests that students' abilities, no matter how high, will be limited if they are not able to self-regulate their learning. A descriptive qualitative research method was employed in this study, conducted in the XI MIPA class at a public high school in Bekasi. The research subjects were selected based on their SRL levels, categorized as high, medium, and low. Data were collected through interviews and CT tests, using data collection techniques such as observation, tests, and interviews. The results showed that students with high SRL levels excelled in all aspects of computational thinking assessment. Conversely, students with medium SRL levels only demonstrated abilities in three out of four indicators: decomposition, abstraction and generalization, and pattern recognition. Meanwhile, students with low SRL levels only showed abilities in one indicator, which was pattern recognition
