Abstract

The study aims to determine the set of the singular matrix 2×2 that forms the group and describes its properties. The type of research was used exploratory research. Using diagonalization of the singular matrix S, whereas a generator matrix, pseudo-identity, and pseudo-inverse methods, we obtained a group singular matrix 2×2 with standard multiplication operations on the matrix, with conditions namely: (1) closed, (2) associative, (3) there was an element of identity, (4) inverse, there was (A)-1 so A x (A)-1 = (A)-1 x A = Is. The group was the abelian group (commutative group). In addition, in the group, Gs satisfied that if Ɐ A, X, Y element Gs was such that A x X = A x Y then X = Y and X x A = Y x A then X = Y. This show that the group can be applied the cancellation properties like the case in nonsingular matrix group. This research provides further research opportunities on the formation of singular matrix groups 3×3 or higher order.

Abstract

This study aims to determine how the ability of mathematical problem solving in the Cartesian coordinate system material in terms of differences in divergent and convergent thinking patterns in class VIII students in semester 1 of SMP Negeri 1 Kediri in the 2019/2020 academic year. This research is a descriptive study using a quantitative approach. The instruments used in this study were the thinking character questionnaire instrument and the problem solving ability test instrument. The thinking character questionnaire instrument was used to select research samples that met the criteria for divergent thinking and convergent thinking. In this study, 11 students thought divergent and 12 students thought convergent. The problem-solving ability test instrument was used to determine the problem-solving ability of the research sample as measured by Polya's assessment guidelines, namely (1) understanding the questions, (2) planning solutions, (3) solving problems, and (4) checking. The results showed that there was no difference in the average score of problem-solving abilities between students with divergent and convergent thinking patterns, namely 66.19 and 66.73. The only difference lies in the steps each student takes. This shows that different mindsets do not affect a person's ability to solve a problem.

Abstract

This study aims to describe the online mathematics learning process and to find out the mathematics learning outcomes in terms of the mathematics disposition of class XII IPA students at SMA Negeri 7 Mataram. This type of research is descriptive qualitative. All students of class XII IPA at SMA Negeri 7 Mataram are the population, where the sample size is 62 students who were selected by cluster random sampling rule. Data collection used a questionnaire, interview and documentation study. From this research, the results show that: (1) The learning process carried out by the teacher changes from direct learning to online learning. In the online learning process, there are several difficulties experienced by students, including students who do not understand the material presented by the teacher, whether the material is delivered in the form of a pdf or video that has been shared. In implementing the online learning process the teacher is not the only source of learning so students are actively looking for other learning reference sources such as videos on YouTube and websites. Assessment of learning outcomes is carried out by providing a written test of the test resulting in that there is no increase in student learning outcomes during learning with an online system. The implementation of online learning cannot be separated from the supervision of parents and teachers. (2) There is a correlation between final semester test scores with students' mathematical dispositions.

Abstract

The aim of this study is to describe the types of errors and their causes made by the seven grade students of SMPN 7 PUJUT in the academic year 2020/2021 in solving algebraic form questions based on the SOLO taxonomy level. This research is a qualitative descriptive study and the instruments used are test questions and interview guides. The subjects of this study were 32 grade seven students of SMPN 7 PUJUT who were selected using purposive sampling technique. After selecting one class, several students were selected according to the SOLO taxonomy level. The results showed that all students made the types of errors according to the basic objects of mathematics, namely fact errors, concept errors, operating errors, and principle errors. The results also showed that the questions given to 32 class seven students of SMPN 7 PUJUT obtained a percentage of the structural level of 31.25%, the unistructural level of 37.5%, the multistructural level of 21.9%, the relational level of 9.38%, and the extended abstract level is 0%. The causes of students making mistakes in solving questions, namely: the cause of factual errors is that students do not understand the meaning of the questions which include what is known and asked and in determining the final result; the cause of misconceptions is that students do not understand the formula used; the cause of the operation error is that the students are not careful in calculating; and the cause of the principle error is that students do not understand the steps to solve it.
