<![CDATA[The purpose of this research, to see the difference between the model of Missouri Mathematics Project learning and conventional learning on mathematical problem-solving abilities in terms of students' self-confidence. The method used in this research is an experimental with kind of a Quasi-Experimental, and the research design is a 2x3 factorial design. The population in this study were all students of class XI MIPA of SMA Negeri 6 Pontianak consist of four classes, with class XI MIPA III and XI MIPA IV samples selected by the Cluster Random Sampling technique. Based on the analysis of variance of two paths with unequal cells it is concluded that: 1) The Missouri Mathematics Project learning model provides better mathematical problem-solving abilities compared to conventional learning in the matrix material. 2) Students who have high, medium and low self-confidence have no difference in the ability to solve mathematical problems in the matrix material. 3) In each learning model, students with high, medium and low self-confidence do not provide differences in mathematical problem solving between self -confidence found in themselves. 4) At each level of students' self-confidence, the Missouri Mathematics Project learning model provides better mathematical problem-solving skills than conventional learning.]]>

<![CDATA[The aim of this research is to analyze students' mathematical representation abilities in terms of cognitive style in the multivariable calculus course taught in semester 4 of the IKIP PGRI Pontianak Mathematics Education Study Program. This research is a qualitative descriptive research in the form of case study research. Research subjects were selected based on their cognitive style which was measured using the geft instrument. Selected subjects were then asked to work on mathematical representation ability questions and then interviewed according to these questions. Based on the research results, it was found that students who had a field dependent cognitive style in symbolic representation were able to link symbols with mathematical concepts, in graphical representation they were able to create images in the form of requested graphs, while in verbal representation they were less able to convey ideas effectively orally. or written. Meanwhile, students with an independent cognitive style in symbolic representation have been able to link symbols with mathematical concepts, in graphic representation they have been able to create images in the form of requested graphics, and in verbal representation they have been able to convey ideas effectively.]]>

<![CDATA[Learning graph theory is an important topic in the world of mathematics and computer science. However, students often face difficulties in understanding the concepts and practical application of graph theory. Therefore, this study aims to apply practicum-based learning methods in teaching graph theory to students. The method used in this study involves the application of practical work through the use of maple. Students are given the opportunity to interactively run experiments, analyze results, and relate them to graph theory concepts. Apart from that, they are also given assignments that focus on the practical application of graph theory in real-world contexts. This research was conducted on students of the Mathematics Education Study Program IKIP PGRI Pontianak, totaling 1 class using an experimental approach. The collected data were analyzed quantitatively to evaluate the effectiveness of practicum-based learning methods in increasing students' understanding of graph theory. The results of the study show that the application of practicum-based learning in graph theory has a positive impact on student understanding. Students show a significant increase in their understanding of graph theory concepts and their ability to apply the theory to real-world situations. In addition, students also provide positive feedback regarding interactive and fun learning experiences.]]>
