Abstract

One of the most effective strategies to improve mathematics teachers' professional competency is providing regular professional development workshops and training sessions for teachers. The aim of this study is to answer the following research questions: (1) How to design PD program for mathematics teachers in Indonesia through online workshop? (2) What are areas that need to be improved so that the program works as planned the next time? A “design research” method adopted for analyzing the process of PD program through collaboration CAR. The participant in this study were 24 mathematics teachers from 12 provinces. Data were collected through evaluation forms, focus group discussion, group meeting and learning logs, then the data were analyzed using grounded theory approach through the process of open, axial, and selective coding. 51% of participants considered the workshop to be very good, and 49% provided suggestions for improvement for further implementation. The two biggest factors to improve are adjusting the time to suit the participants and considering the technical issues that teachers might face. Based on the evaluation form each week, teachers considered that they need to join wokshop related to related to the Kurikulum Merdeka implementation, teaching media, ICT integration, and book publishing.

Abstract

Difficulties in learning can be one of the factors that cause learning obstacles. Learning obstacles can interfere with students' learning process internally and externally. This study aims to analyze learning obstacles that arise at the junior high school level to be the basis for making further designs. The research methodology used is a systematic literature review by collecting articles related to learning obstacles at the junior high school level. The data analysis technique used is data extraction. The data obtained were 15 articles related to learning obstacles in mathematics material at the junior high school level in the 2021-2024 period. The results obtained were ontogenic barriers, epistemological barriers, and didactic barriers. The ontogenic barriers obtained were students' unpreparedness during learning, lack of interest and motivation to learn, and lack of understanding of prerequisite material. The epistemological barriers obtained were misconceptions, unable to understand, identify, and analyze problems, inaccuracy, and limitations in solving the questions given. The didactic barriers obtained were teacher-centered learning, fast learning rhythm, inappropriate teaching material arrangements, and inadequate school facilities. Based on the obstacles obtained, a learning flow can be designed, and a didactic design can be developed to minimize the emergence of these learning obstacles.

Abstract

Self-confidence is considered a key psychological factor in enhancing students' ability to communicate mathematical ideas effectively. However, few studies have explored this relationship in the context of lower secondary education. This study aims to investigate the effect of self-confidence on the mathematical communication skills of eighth-grade students at SMP Negeri 5 Mataram during the 2024/2025 academic year. A quantitative approach with an ex post facto design was employed. A purposive sample of 29 students was selected, and data were collected using a self-confidence questionnaire and a mathematical communication skills test on the topic of systems of linear equations in two variables. The data were analyzed using descriptive statistics and simple linear regression. With the regression equation, the correlation coefficient, and the coefficient of determination. The results indicate that self-confidence has a significant positive effect on students' mathematical communication skills. These findings underscore the importance of cultivating students' self-confidence to support their development of mathematical communication skills.

Abstract This research aims to describe the critical thinking abilities in algebra material as viewed from the personality types of eighth-grade students at SMPN 8 Mataram. This type of research uses a descriptive qualitative method. The instruments used include a personality type test, specifically the Big Five personality questionnaire, critical thinking ability tests, and interview guidelines. Data from ten subjects were chosen from a group of 68 students based on their respective personality types for in-depth interviews. The results of the research show that students with openness to experience and neuroticism personality traits have moderate critical thinking abilities. In this case, students are able to meet 2 or 3 indicators. Students with openness and neuroticism personality types tend to be dominant in the analysis and evaluation indicators, while they tend to score lower in the interpretation and inference indicators. Students with extraversion and agreeableness personality traits have moderate critical thinking abilities as well. In this case, students are able to meet 2 or 3 indicators. Students with extraversion and agreeableness types tend to be more dominant in the analysis, evaluation, and inference indicators but tend to score lower in the interpretation indicator. Furthermore, students with conscientiousness personality traits have high critical thinking abilities. In this case, students are able to meet 3 or 4 indicators. Students with conscientiousness tend to be dominant in the interpretation, analysis, and evaluation indicators, while they tend to score lower in the inference indicator.

Abstract

Penelitian ini bertujuan untuk menganalisis ada tidaknya hubungan signifikan antara kemampuan awal terhadap kemampuan pemecahan masalah matematis. Metode penelitian menggunakan mixed method dengan desain sequential explanatory yang melibatkan 24 siswa kelas VIII di salah satu SMP swasta di kota Mataram tahun ajaran 2024/2025. Teknik pengumpulan data menggunakan instrumen tes dan pedoman wawancara. Instrumen tes terdiri dari dua soal uraian pada tes kemampuan awal dan tes kemampuan pemecahan masalah matematis. Hasil penelitian menunjukkan nilai coefficient correlation sebesar  ρ = 0,719  dengan signifikansi  sig. (2-tailed) < 0,001 (α = 0,05), menunjukkan adanya hubungan positif, kuat dan signifikan antara kemampuan awal dengan kemampuan pemecahan masalah matematis. Analisis kualitatif memperkuat temuan kuantitatif bahwa siswa dengan kemampuan awal tinggi dan rendah konsisten memperoleh skor pemecahan masalah sesuai kategori kemampuan awalnya. Sedangkan siswa dengan kemampuan awal sedang cenderung memperoleh skor pemecahan masalah sedang. Penelitian ini membuktikan bahwa kemampuan awal matematis merupakan prediktor yang signifikan dalam menentukan keberhasilan siswa dalam memecahkan masalah matematis, sehingga dapat dijadikan pertimbangan dalam merancang strategi pembelajaran yang lebih optimal.

Abstract

This study was motivated by students’ low mathematical problem-solving skills, the lack of innovative learning models, and the limited use of technology in learning media. The purpose of this research is to determine the effect of a problem-based learning model assisted by digital student worksheets on students’ mathematical problem-solving skills. This quasi-experimental research involved all eighth-grade students at one of the junior high schools in mataram city. The sample consisted of class VIII A as the experimental class, which received PBL with digital worksheets, and class VIII B as the control class, which received PBL with printed worksheets. Data were collected using a mathematical problem-solving test and analyzed using a t-test and effect size. The results showed that the use of digital worksheets had a significant effect on students’ mathematical problem-solving skills. The average score of the experimental class increased from 47.75 (pretest) to 70.12 (posttest), while the control class increased from 49.46 to 62.05. The t-test showed that   at a 0.05 significance level. The effect size was 0.71, categorized as large, indicating that the applied model and media were effective. This study shows that digital worksheets in problem-based learning can enhance students’ problem-solving skills.
