Abstract

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.

Abstract

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.

Abstract

This study aims to determine the application of the Problem Based Learning learning model to mathematical communication skills in terms of independent learning on set material in class VII SMP Negeri 01 Tayan Hulu. The research form used is quasi-experimental designs, with a 2×3 factorial design. The population in this study were students of class VII A and students of class VII B. The sample in this study was one class selected by cluster random sampling. Data collection techniques used are direct communication techniques and measurement techniques with data collection tools in the form of questionnaires and test questions in the form of essays. The data analysis technique used was the analysis of two dissimilar cell paths with the normality test using the Lilifors test, homogeneity using the Bartlett test and continued with the multiple comparison test using the Scheffe method. The results of this study are (1) the mathematical communication of students who follow the problem-based learning model is better than students who follow the conventional learning model, (2) the ability of mathematical communication between students who have high learning independence is better than moderate after the implementation of the model learning problem based learning. (3) students' mathematical communication skills in the moderate learning independence category were better than students in the low learning independence category after applying the problem-based learning model. (4) at the level of independent learning, problem-based learning models provide better mathematical communication skills than conventional learning models.

Abstract

This study aims to analyze the mathematical creative thinking ability of grade VIII students in solving quadrilateral and triangle problems in one of the swasta junior high schools in Pontianak. This research used descriptive method with qualitative approach. Data were collected through essay tests and interviews to provide an overview of students' mathematical creative thinking ability. The results showed that 21.28% of students were in the low ability category, with scores below the difference between the mean and standard deviation of students' scores. In the medium category, 61.7% of students scored above or equal to the low group score criteria but below the high group score criteria. Meanwhile, 17.02% of students were in the high category, with scores above or equal to the sum of the mean and standard deviation of student scores. Analysis of the indicators of creative thinking ability shows that students have very good abilities in the indicators of fluency, flexibility, and elaboration. However, in the originality indicator, students are still in the good category. These findings indicate the need for improvement in the originality aspect of students' creative thinking to achieve more optimal results in mathematical problem solving.

Abstract

This research aims to determine whether there are differences in mathematical problem solving abilities through the contextual learning model assisted by Quizizz in terms of visual spatial intelligence. This research is a quantitative research type of True Experimental Design. The research subjects were class VIII students at SMPN 17 Pontianak with a total of 60 students. The samples in this study were class VIII B as an experimental class using the contextual learning model assisted by Quizzizz and class VIII A as a control class using a conventional learning model. Data was obtained from the mathematical problem-solving ability test given to students. The data analysis technique used a two-way anava test and an advanced test using a double comparison test with the Sheffe method. Based on the results of the analysis and discussion of the research data, the results were obtained that the ability to solve mathematical problems using the quizizz-assisted contextual learning model is better than the ability to solve mathematical problems using the conventional learning model. There is an interaction between the quizizz-assisted contextual learning model and students' spatial visual intelligence on mathematical problem solving
