Abstract

This study aims to find out the effect of the implementation of classroom management with the Visual, Auditory and Kinesthetic learning model (VAK) on the results of students' mathematics learning on the material system of linear equations of two variables (SPLDV) in SMPN 2 Rantau Selatan. This study used a quasi-experimental type of research with a pretest-posttest control group design. Data were collected through closed questionnaires and test questions in the form of pre-test and post-test each of which totaled 5 questions for each test—data analysis technique using multiple linear regression analysis technique. The results of the study show that the application of classroom management and the VAK learning model individually and together has a positive and significant effect on students' mathematics learning outcomes. The contribution of classroom management and the VAK learning model explains about 73.6% of the variation in student mathematics learning outcomes, according to the coefficient of determination (Adj R2 ) of 0.736. While the rest is influenced by other variables that are not examined by the researcher. This study concludes that classroom management using visual, auditory, and kinesthetic learning models affects students' mathematics learning outcomes, especially in the context of SPLDV. The implications of these findings guide educational practitioners in improving the effectiveness of mathematics learning in schools.

Abstract

This study aims to increase students' interest in mathematics. Students can use number card learning media as an alternative method of learning integers (addition and subtraction). In mathematics, the material on integers (addition and subtraction) discusses abstract properties in mathematics. Based on this study, the study was conducted through observation of class VII students at MTs Altihadul Wathoniayah. This research takes the type of quantitative research through an experimental approach and uses a Pretest-Posttest Design. This research involves all class VII MTs Al Ittihadul Wathoniyah, both class VII-A and VII-B. However, the sample used randomly is type VII-A which consists of 30 samples used in this study to conduct tests to collect data on reasoning skills and mathematics learning outcomes. After testing with the hypothesis that the calculated value is greater than the table's t value. The results of the data show that the use of number cards in conducting research on mathematics learning media is effective in increasing students' interest in learning mathematics subjects and achieving satisfactory results.

Abstract

A student's ability to solve math problems is very, very low because in solving math problems, the learning process does not accustom students to think more creatively. This is because the learning process in the teacher's class still applies conventional methods, and the students in the class have not yet achieved scores above the KKM. This study aims to see the Creative Problem Solving learning model as a series of learning in solving and solving problems systematically based on student creativity to produce effective solutions. This research is a quasi-experimental research using purposive sampling technique. The instrument used in this research is a test of the ability to solve mathematical problems in the form of a written test, a result test and an observation sheet on the implementation of the learning process. The data analysis techniques used are descriptive statistical analysis and inferential statistical analysis. The results of the study show that the mathematics learning of students using the CPS learning model on the ability to solve mathematical problems of students is better than the results of mathematical learning of students who have followed conventional learning which means that there is an influence of creative problem solving learning on the ability to solve mathematical problems of high school students regarding linear inequalities .
