Abstract

This research is quantitative research. The research was conducted on November 5-24, 2018. The population in this study were class X students of SMA Negeri 1 Jelimpo in the 2018/2019 school year of Landak Regency, which consisted of class X MIA, X IIS A and X IIS B totaling 109 students. The sampling technique is Cluster Random Sampling. Data collection methods used tests, questionnaires, and documentation. Data analysis techniques with prerequisite test consisting of balance test, normality test and homogeneity test, followed by a hypothesis test consisting of two-way unequal cell anava test and further test. Based on the calculation results obtained: (1) the TAI method is better than the Pair Checks method of understanding concepts, (2) high learning interest has better understanding of concepts than moderate and low learning interest, and moderate learning interest is better than low interest in learning, ( 3) In each learning method high learning interest has better understanding of concepts than moderate and low learning interest, and moderate learning interest is better than low interest in learning, (4) At each level of learning interest students have high and moderate learning interest in the TAI method and the Pair Checks method has the same good concept, so for students who have a low interest in learning with the TAI method they have a better understanding of the concepts than students with the Pair Checks method.

Abstract

This study aims to determine the mathematical communication ability in terms of students self- confidence in solving problems related to statistical material. The type of research used is qualitative descriptive research. This research was conducted in the even semester of the 2024/2025 academic year. The subjects in this study were 25 students, taken 3 students with each student with high, medium, and low self-confidence. The data collection technique used 3 essay test questions on statistical material, a self-confidence questionnaire, and interviews. The data obtained were then analyzed based on indicators of mathematical communication ability, namely, presenting mathematical symbols, making mathematical models, and writing. The results of the study showed that students with high self-confidence had high mathematical communication skills and were able to meet all indicators of mathematical communication ability. Students with medium and low self-confidence had medium mathematical communication skills and met two indicators of mathematical communication ability. Students with medium and low self-confidence were only able to meet two indicators, namely presenting mathematical symbols and writing. Therefore, teachers are expected to be able to improve students' mathematical communication skills by increasing joint discussion activities, presentations, question and answer sessions between teachers and students and students with students, as well as providing students with lots of practice questions so that students' self-confidence also increases.

Abstract

In the trigonometry course, the learning achievement achieved by students is not optimal because many students get scores below 70. Researchers find out the causes of these problems, one of which is that the teacher still uses the lecture method and assignments in the learning process. This causes students to only listen to the material without going through the process of trying and finding themselves. The researcher gave the treatment of the Project-Based Learning learning model and conventional learning model so that the purpose of this study was to determine the difference in learning achievement of Mathematics Education Study Program students at Palangka Raya University as prospective teachers who were treated with the Project-Based Learning learning model and conventional learning model. The population of this study was all 1st semester students of the 2024/2025 academic year of the mathematics education study program at Palangka Raya University. Before conducting the analysis using the t-test of two independent samples, the prerequisite test was carried out: normality test with Kolmogorov-Smirnov and homogeneity test with Levene. The results of this study are that there are differences in the learning achievement of students of the Mathematics Education Study Program at Palangka Raya University as prospective teachers who are treated with the Project-Based Learning learning model and the conventional learning model. Furthermore, students in the experimental class using the Project-Based Learning learning model obtained an average achievement of 81.379, while the control class using the conventional learning model obtained an average achievement of 72.008.
