Abstract

ABSTRACT This study discusses how to improve students' abilities after using a problem-based learning model in mathematics learning material. This type of research is quantitative research. Quantitative research consists of experimental methods and survey methods. In this study using the experimental method. The experimental method used to find interaction. The research design used was a quasi-experimental design with class 2 research taken from class VIII SMP in one of the cities of Sukabumi. The research sample used cluster random sampling technique. The research design used in this study was the design of the pretest-posttest control group. The instrument used in this study is essay questions as many as 6 items which have been declared valid and reliable. Based on the prerequisite test of the data produced by the research data, it is not normally distributed so that further testing is carried out, namely the mann-withney test. From the data analysis, the average posttest value of the experimental students with the problem based learning learning model was 18,24 and the average score of the posttest control class students without using the problem based learning learning model was 15,17. There is a significant difference in student learning outcomes, this is evidenced by the mann-withney test so this study rejects H0 and accepts H1. Thus, it can be concluded that there is an increase in learning outcomes in mathematical punishment abilities of students who use learning by using problem-based learning models on the material to get a flat side space.

Abstract

The ability to understand mathematical concepts is one important component that must be mastered and developed. The result of the pre-study show that the ability to understandmathematical concepts of students of MTS ANNUR Karang Rejo is still low, this can be seen from the resultsof the ability to understand mathematical concepts of students in the academic year 2019/2020 obtained the above values ​​(KKM) with a value of ≥70 of 22 from 60 students. Researchers are interested in applying the learning model aptitude treatment interaction (ATI). The purpose of this study was to determine the effect of the aptitude treatment interaction (ATI) learning model to improve the ability to understand mathematical concepts in terms of students learning independence. This researchis a type of research Quasy Experimental Design. The instrument used to collect data is a test of the ability to understand mathematical concepts. Analysis of the data of this research is the analysis of variance of two paths with unequal cells. Based on the results of the study it can be concluded that: 1) there is an effect of the application of the learning model aptitude treatment interaction (ATI) to improve the ability to understand mathematical concepts compared to conventional learning, 2) there is an effect of increasing the ability to understand mathematical concepts that have high, medium, and low learning independence . 3) there is no interaction effect between the learning model and learning independence to improve students' mathematical concept understanding abilities.

Abstract

Mathematical communication skills are essential for learners in math learning. Increased numerical ability of students impact on the results of the study aims to determine whether there is improvement in the mathematical communication skills of learners by using methods learning problem solving modification. Method used is quantitative method. The types of research used are Quasy experiments and design experiments used in the design of non-equivalence control groups and data analysis used with one way Anava. The results of the study are Fhitung = 11,186, Ftabel = 3.09 then H0 rejected, then it can be concluded the research has an influence that is not equal to the mathematical communication skills of learners.

Abstract

The research objectives are: (1) To find out how student learning outcomes after the use of Wingeom application in exposure to three-dimensional subject matter, (2) To find out how students respond to learning by using Wingeom application in exposure to three-dimensional material, (3) To find out how student activities with exposure to three-dimensional subject matter using Wingeom application, (4) To find out how to manage learning by exposing three-dimensional subject matter using the Wingeom application, (5) To find out whether Wingeom application is effectively used in exposure to three-dimensional subject matter. This study uses a quantitative approach to 27 research subjects who are students of class XII MIA 1 in SMA Negeri 2 Pangkep. Data collection using test instruments, questionnaires and observations. Data analysis uses descriptive and inferential statistical analysis. The results of this study indicate that: (1) Student learning outcomes with the Wingeom application in exposure to the three dimensional subject matter are good, (2) Student responses during the learning process take place with the use of the Wingeom application in the exposure to the three dimensional material is positive, (3) Student activities when the learning process takes place with the presentation of three-dimensional subject matter using the Wingeom application is active, (4) The implementation of learning by exposing the three-dimensional subject matter using the Wingeom application is very good, (5) the Wingeom application is effectively used in exposure to the three-dimensional subject matter.

Abstract

This type of research is an experimental study involving two groups given different treatments. This study aims to find out (1) how much the mathematics learning outcomes of fourth grade students of Makassar City Rama Sejahtera Private Elementary School were taught using a problem solving approach, (2) How much the mathematics learning outcomes of fourth grade Rama Sejahtera Private Elementary School Makassar were taught using the problem posing approach, (3) There is a difference between the results of mathematics learning in fourth grade students of Rama Sejahtera Private Elementary School in Makassar City between those taught using a problem solving approach and those taught using a problem posing approach. The population of this study was fourth grade students of Makassar City Rama Sejahtera Private Elementary School in the even semester 2018/2019 which consisted of 3 classes and 2 randomly selected classes as the research sample. Data collection techniques were carried out using learning outcomes tests (pretest and posttest) and observation sheets. The collected data was analyzed using descriptive and inferential statistical analysis techniques. The results obtained from descriptive statistical analysis are: (1) Mathematics learning outcomes of students taught by using problem solving approaches are in the high category with an average of 73.36 and standard deviation of 10.20 of the ideal score of 100. (2) Learning outcomes Mathematics students taught by the problem posing approach are in the low category with an average of 67.96 and standard deviation of 8.29 from the ideal score of 100. From the results of inferential statistical analysis it can be concluded that the mathematics learning outcomes of students taught by problem solving approaches are different from mathematics learning outcomes of students taught by using the problem posing approach.
