Abstract

Mathematics learning in elementary schools requires the application of appropriate learning models so that student learning outcomes can be optimal. This article is compiled using a literature study method that analyzes various research results related to the influence of Jigsaw-type cooperative learning on mathematics learning outcomes in elementary schools. The Jigsaw-type cooperative learning model places students in small heterogeneous groups, where each member is responsible for studying and delivering certain parts of the material to their original group. Based on the analysis of various studies, it was found that the application of the Jigsaw model was consistently able to improve students' mathematics learning outcomes at various grade levels. This increase is reflected in the increase in average grades, percentage of learning completion, and student absorption in each learning cycle. The results of statistical tests in several studies also showed that the influence of the Jigsaw model on learning outcomes was scientifically significant. Thus, this study confirms that Jigsaw-type cooperative learning is effectively implemented as a strategy to improve mathematics learning outcomes in elementary schools. These findings are expected to be a reference for teachers and educational policymakers in choosing an innovative and results-oriented learning approach.

Abstract

Mathematical disposition is an affective ability that is important for students to have because through this ability, students' attitudes in facing problems in mathematics will be resolved properly. One of the efforts that can be done to improve mathematical disposition is by implementing problem-based learning. By providing contextual problems in mathematics learning, it can have an impact on interest, desire and awareness in the form of a strong tendency to think and behave towards mathematics and see the usefulness of mathematics. This research aims to analyze students' mathematical disposition using problem based learning.This type of research is Quasi-experimental research.This research was implemented at SMP Negeri 1 Pangkalan Susu. The population of this research was students of class IX. The sample used was students of class IX-1 as the experimental class and IX-2 as the control class. Based on the results of t-test used in the research, the t-count value was 3,508 and the t-table value for a value of 1.67. This means that the t-count value > t-table namely 3,508 > 1,67. The results of this research state that the mathematical disposition of students who use problem-based learning is better than the mathematical disposition of students who use conventional learning.

Abstract

The evaluation of learning outcomes such as the Mid-Semester Exam (UTS) and the Final Semester Exam (UAS) often shows significant differences in scores, which can be influenced by various factors such as teaching methods and student motivation. The purpose of this study is to analyze the comparison of student learning outcomes based on UTS and UAS scores using the Wilcoxon Signed Rank Test, a non-parametric statistical test. The research was conducted on fourth-grade students at SDN Rawa Badak Utara 23 using a descriptive quantitative approach. Data were obtained from the UTS and UAS scores in Mathematics, which were then analyzed using the Kolmogorov-Smirnov test for normality and Wilcoxon test to determine the difference in scores. The results of the Wilcoxon test showed a Z value of -1.930 with a significance of 0.054. Since the significance value of 0.054 > 0.05, it can be concluded that there is no significant difference between the UTS and UAS scores of the students. This analysis indicates that conducting evaluations at two different times does not always reflect a significant improvement in student learning outcomes. Therefore, evaluation approaches should consider broader factors to enhance the effectiveness of learning.

Abstract

Studying overtime is a common habit among students, especially when facing deadlines for assignments and exams, which has the potential to affect health and negatively affect sleep quality. Continuous overtime study system will affect the quality of sleep of students resulting in physical and mental disorders. This situation will affect the academic decline, namely the results of the preparation of tasks to be less than optimal. Many students feel pressured by their academic load and daily activities, causing serious sleep disturbances. The large number of tasks that accumulate and the continuous overtime study system will affect the quality of student sleep, resulting in physical and mental balance disorders. This situation will affect academic decline, namely learning outcomes and assignments become less than optimal. This study aims to analyze the effect of overtime learning system on the quality of sleep of students of Universitas Pendidikan Indonesia Purwakarta Campus. The research we conducted used a quantitative approach by conducting a survey of 50 students from various study programs. Data were analyzed using normality, homogeneity and wilxocon tests to identify the relationship between the influence of the overtime study system and sleep quality. The results show that there is a significant influence between the overtime study system and students' sleep quality, with disrupted sleep patterns and daytime fatigue leading to a decrease in students' concentration.

Abstract

Understanding the basic concepts of mathematics is an important foundation for students of the Mathematics Education Study Program to be able to become competent educators in the future. However, there are still many students who have difficulty mastering these concepts. This study aims to determine the level of understanding of basic mathematical concepts of fifth-semester students and identify the factors that affect them. The research used a descriptive survey method with an instrument in the form of a questionnaire distributed to 12 students. The data collected was analyzed descriptively to illustrate the level of understanding of basic concepts and their relevance to daily life. The survey results show that most students have a fairly good understanding of basic mathematical concepts, but there are still challenges in terms of applying concepts, learning independence, and confidence in facing difficult material. The conclusion of this study is that a more contextual learning approach is needed, the provision of additional support such as tutorials or remedial learning, and a conducive learning environment to improve students' overall understanding.
