Abstract

This study aimed to determine that the failure of students to evaluate mathematical explanations based on mathematics is influenced by sociomathematical norms, teaching authority, and classroom mathematics practice. The research method used is the case study method. The research data were obtained from inside and outside the research class. The data in the research class were in the form of field notes, video recordings of the class, video recordings of student group work, and student work. Data outside the research class is the result of interviews with three interview subjects. By studying the three evaluation methods students used in evaluating explanations, it was found that each student applied a different evaluation method at different times. The three evaluation methods contributed to some of the difficulties students experience in evaluating their mathematical descriptions. The results indicate that the failure of students in evaluating explanations is not solely due to errors in choosing the method, approach, or learning model used but can be caused by sociomathematical norms, authority, and classroom mathematics practices applied in the classroom.

Abstract

The numerical method is one method that can be used to solve differential equations, both differential equations that are easy or difficult to solve analytically. The solution obtained from the calculation results is an approximate solution or a solution that approaches an analytic solution, not an analytic solution. That is, in solving differential equations numerically, there is always an error. In this paper, an analytical solution is described and described and the application of different methods in solving a damped mass spring system with a known limit value. The error between the analytic and numerical solutions obtained is very small.

Abstract

STRENGTHENING TEACHER PEDAGOGICAL COMPETENCIES THROUGH THE USE OF DYNAMIC GEOMETRY SOFTWARE IN MATHEMATICS LEARNING. The selection of strategies, methods, models, and media of appropriate mathematics learning is a form of implementation of a teacher's pedagogical competence. In the 2013 curriculum, the teacher not only sets a scientific approach as a reference in implementing the learning process but also demands innovation to accommodate the right media as well. The role of instructional media, especially dynamic media, is very important in learning mathematics in both elementary and junior high schools. The media was used to explain abstract mathematical problems to be concrete, motivate students, stimulate student learning activities, and help the effectiveness of the learning process. Technological devices such as computers are one of the tools that can be used as dynamic mathematics learning media. Mathematical learning collaboration with ICT devices has been widely carried out in urban and rural areas in Indonesia. Dynamic Geometry Software (DGS) in the form of GeoGebra is a learning medium specifically developed to facilitate the learning of geometry, algebra, and calculus. Therefore, this community service activity (PkM) is intended to strengthen the teacher's pedagogical competence through the use of dynamic learning media using Dynamic Geometry Software (DGS) in the form of GeoGebra in mathematics learning in junior high schools. This PkM aims to train teachers to be able to operate or create mathematics learning media assisted by DGS, especially in learning geometry to students. By making their own, teachers can add insight and increase creativity in making learning media. The supported subjects in these community service activities were junior high school mathematics teachers in Ruteng City. As for the results obtained after the PKM activities, the teachers can operate and create mathematics learning media using DGS in the form of GeoGebra.

Abstract

This study aims to compare the mathematical problem solving abilities of students who are taught using the problemc based learning model and the mathematical problem solving abilities of students who are taught using conventional learning models in class VII students of SMP Negeri 18 Satarmese in the 2022/2023 academic year.Pretestposttest control group design is used in the quasi-experimental design of the research. There were a total of 58 students in class VII at SMP Negeri 18 Satarmese who participated in this study. Sampling in this used non-probability sampling or a sampling technique that did not provide equal opportunities or opportunities for each elemnt or member of the population to be selected as a sample, so the researchers made class VII A as the experimental class and class VII B as the control totaling 29 participants. A description-based mathematical problem solving ability test was used to gather the information. Prerequisite tests, such as homogeneity and normality tests, were carried out prior to the analysis of the data. The data from both groupd come from a population that is normally distributed and has a homogeneous variance, as demonstrated by the calculations for the normality and homogeneity tests. Then a hypothesis test was AL-FIKRU: JURNAL PENDIDIKAN DAN SAINS, 4 (1), 2023 | e-ISSN 2774-5627 p-ISSN 2747-134948carried out to see the studentd’ mathematical problem solving abilities. The N-gain score data were the ones that were analyzed using the independent t test statistical method.Based on the data analysis result obtained that the calculation result = 8,03 and = 1,67 at the significant level and degrees of freedom. Because price = 8,03 > price = 1,67, it is accepted and rejected. Therefore, there are differences in students mathematical problem solving abilities taught using the Problem Based Learning model with students mathematical problem solving abilities taught using conventional models. Based on the research results, recommendations for further research are to carry out similar research with other learning models and other classes.Keywords: Conventional Learning, the Problem Based Learning (PBL) model, the ability to solve Mathematical Problems

Abstract

Kemampuan komunikasi matematis sangat penting bagi siswa untuk dapat mengungkapkan ide atau pemikirannya terhadap masalah matematika. Penelitian ini bertujuan untuk mengetahui hubungan kemampuan komunikasi matematis siswa SMP dengan self-regulation dan self-efficacy siswa tersebut. Populasinya adalah 120 siswa kelas VIII. Pengambilan sampel dilakukan dengan menggunakan teknik simple random sampling dan diperoleh sampel sebanyak 60 siswa di SMP Fransiskus Xaverius Ruteng. Instrumen yang digunakan adalah tes untuk mengukur kemampuan komunikasi matematis dan angket untuk mengukur self-regulation dan self-efficacy siswa. Ketiga instrumen tersebut sebelumnya telah dibuktikan validitas dengan uji Pearson Product Moment dan reliabilitasnya dengan uji Alpha Cronbach. Hasil penelitian ini menunjukkan bahwa self-regulation dan self-efficacy secara simultan memiliki hubungan yang signifikan terhadap kemampuan komunikasi matematis siswa. Analisis menunjukkan bahwa secara simultan kontribusi self-regulation dan self-efficacy terhadap kemampuan komunikasi matematis sebesar 24,6016% sedangkan sisanya sebesar 75,3984% dijelaskan oleh variabel lain yang tidak diteliti oleh peneliti. Nilai signifikansi antara self-regulation dan self-efficacy secara simultan pada kemampuan komunikasi matematis adalah 0,000 < 0,05 yang artinya terdapat hubungan yang signifikan antara self-regulation dan self-efficacy secara simultan dengan kemampuan komunikasi matematis siswa. Hal ini menyimpulkan bahwa siswa yang memiliki self-regulation dan/atau self-efficacy yang baik akan berdampak positif pada kemampuan komunikasi matematisnya.
