Abstract

This  research was conducted with the aim of analyzing and describing the mathematical, spatial visualization abilities of junior high school students in class VIII in solving spatial geometry math problems with the help of augmented reality-based applications in the categories of high, medium, and ability students. The research was conducted at SMPN 3 Karawang Barat, with a descriptive qualitative method. The process of collecting data was carried out using the test and interview methods to the research subjects. The results of the research show that high mathematical  spatial visualization skills have the characteristics of imagination, use of concepts, problem solving and pattern search that are quite good in solving problems. Then, the medium mathematical, spatial visualization ability has good imaginative characteristics. And those with low mathematical, spatial visualization skills have poor imagining characteristics, use of concepts, problem solving and pattern search and experience many difficulties in various cases.

Abstract

The preliminary study at SMP Negeri 5 Pati obtained an average score of 33,44. This shows that the students' mathematical problem solving ability is still low. The purpose of this study was to test the average mathematical problem solving ability of class students who were given the Project Based Learning model assisted by the Lubuk ethnomathematics module which was better than the class with direct learning. The research method used was quantitative. Sampling with purposive sampling technique. Analysis of the data used the t-test of two independent samples. The results showed that the average mathematical problem solving ability of students who were taught the PjBL model assisted by the Lubuk ethnomathematics e-module was better than students who received direct learning. The conclusion of this study is that the PjBL model assisted by the Lubuk ethnomathematics e-module has an effect on students' mathematical problem solving abilities.

Abstract

Many students' perceptions indicate that mathematics is a difficult subject because it is always related to formulas and calculations. In addition, many students still have difficulty in solving story problems so that many make mistakes in doing them. Therefore, this study aims to describe the learning difficulties experienced by students in solving story problems, one of which is SPLTV material. This study uses a qualitative approach with a descriptive method. Procedures for data collection through tests, interviews, and documentation. The results showed that the biggest difficulty experienced by students was difficulty in performing mathematical procedures with a percentage of 74%. The contributing factors are because students are less careful in carrying out calculations, using incorrect arithmetic operations resulting in inaccurate answers and the completion process is less clear, and inaccuracy in concluding the final answer

Abstract

This research aims to determine the improvement of students' conceptual understanding skills with MURDER collaborative learning and student responses to the application of MURDER collaborative learning. This research is a research experiment (quasi experimental design) with the design of non-equivalent control group design. The population is all students of grade VII SMP Negeri 1 Lalolae as much as 54 people. Sampling with a totally sampling technique obtained the VIIA class as the experimental class and the VIIB class as the control class. The hypothesis test indicates that at the level of the significance α = 0.05, the value of tcount = 3,863 > ttable = 2,022. That means that H0 rejected and H1 accepted. So it can be concluded that MURDER collaborative learning can improve students' understanding of mathematical concepts. based on the results of the student response questionnaire analysis, the percentage of the average score for student responses was 84.68% and was included in the very good category.
