Abstract

This study aims to determine students’ mathematical literacy skills in solving PISA mathematical problems. Mathematical literacy is the capacity of individuals to formulate, use, and interpret mathematics in various contexts. Students’ mathematical literacy skills can be seen in the way students work in solving PISA questions. This study is qualitative descriptive research. Data from the analysis of students’ mathematical literacy skills were obtained through tests in the form of descriptive questions adopted from PISA questions, analysis based on indicators of mathematical literacy skill according to PISA, and the interview results with students who worked on the PISA questions. This study shows that students’ mathematical literacy skills were in the medium to the low category; this can be seen from the percentage of students’ answer scores in working on PISA questions. Therefore, it is necessary to provide reasoning questions such as PISA questions to help students improve their mathematical literacy skills.

Abstract

The low quality of mathematics learning that has an impact on the lack of improvement in students' mathematics abilities is the main reason for implementing the lesson study community service activity of applying math city maps in mathematics learning. Due to this reason, the activity was carried out using a procedure that includes the stages of planning, implementation, and evaluation. The success of the community service activity was analyzed using a questionnaire on the success and satisfaction of partners distributed to 13 mathematics teachers at Majene regency. The results of the activity showed a positive influence of the activity on teachers where the average evaluation aspect reached a percentage of 88.3%. From the results of the implementation of the activity, it was also concluded that teachers were interested in implementing lesson study as an initial step in improving the quality of students' mathematics learning

Abstract

This study seeks to evaluate the validity and reliability of the outcomes derived from the adoption of the Representational Systems and Chemical Reactions Diagnostic Instrument (RSCRDI). This research employs a quantitative, survey-based approach, involving 69 prospective chemistry teachers at a university in Indonesia. Prior to implementation, the instrument was translated from English to Indonesian using the back-translation method. The collected data were subsequently analyzed using Winstep, yielding strong validity and reliability results. The instrument exhibited a Cronbach's alpha of 0.65, a person reliability of 0.60, and an item reliability of 0.76. Furthermore, the construct validation results were favorable, as evidenced by mean score (MNSQ), Z-standard (ZSTD), and point measure correlation (Pt Mea Corr) indices. These findings indicate that the RSCRDI is a valid and reliable instrument for assessing conceptual understanding among prospective chemistry teachers in Indonesia.

Abstract

In today’s digital era, educational technology—particularly AI tools like ChatGPT—offers innovative solutions to enhance mathematics education. This study explores how Gen-Z pre-service mathematics teachers accept and use ChatGPT, guided by TPB and UTAUT2 frameworks, while also examining the roles of gender and year of study in shaping their behavior. This quantitative study used a cross-sectional survey with 157 Gen-Z pre-service mathematics teachers, selected via convenience sampling. Data were gathered using a validated questionnaire based on UTAUT, showing high reliability (α = 0.97). Analysis involved descriptive statistics, Pearson correlation, t-tests, and ANOVA to examine ChatGPT acceptance and use by gender and year of study. Descriptive statistics confirmed normal distribution, supporting parametric tests. Pearson coefficients revealed strong, significant correlations between behavioral intention and variables like social influence (r = 0.785) and perceived behavioral control (r = 0.777). Actual ChatGPT use was most correlated with perceived behavioral control (r = 0.784) and attitude (r = 0.738). All predictors, including performance expectancy, effort expectancy, and hedonic motivation, showed positive, significant relationships, supporting the relevance of UTAUT 2 and TPB frameworks in explaining ChatGPT adoption in educational contexts.

Abstract

Laboratorium Ilmu Pengetahuan Alam (IPA) sarana penting dalam proses pembelajaran IPA di tingkat sekolah menengah pertama (SMP). Edukasi keselamatan laboratorium di tingkat sekolah menengah memiliki dampak positif terhadap peningkatan kesadaran dan perilaku aman siswa. Pengenalan simbol dan tanda bahaya merupakan langkah awal yang wajib dilakukan sebelum siswa menggunakan laboratorium sekolah. Kegiatan ini dilaksanakan guna untuk meningkatkan kesadaran dan pemahaman siswa terhadap pentingnya keselamatan kerja di laboratorium IPA. Pengabdian ini dilaksanakan dalam tiga tahap yaitu tahap persiapan, pelaksanaan, dan tahap akhir yang diikuti oleh 50 siswa kelas VIII. Siswa-siswi SMP Negeri 4 Majene telah memperoleh pemahaman yang baik mengenai arti dan pentingnya simbol-simbol keselamatan kerja serta tindakan yang harus diambil saat terjadi kecelakaan di laboratorium IPA.

Abstract

Mathematical literacy is a fundamental cognitive competency that enables students to analyze mathematical situations and communicate their reasoning effectively. Although numerous studies have investigated mathematical literacy, research that specifically examines students’ performance on HOTS-type mathematical tasks from a gender perspective remains scarce. This study aims to describe students’ mathematical literacy skills in solving HOTS problems based on gender differences. Employing a descriptive qualitative design, the study involved 35 students from class XII IPA 1, consisting of 7 males and 28 females. Data were collected through tests and semi-structured interviews, then analyzed using data reduction, data display, and conclusion drawing techniques. The findings indicate that in analyzing-type HOTS items (C4), male students generally met only the communication indicator, with one male student demonstrating mastery of all indicators. Conversely, female students consistently fulfilled all mathematical literacy indicators. A similar pattern emerged in evaluating-type HOTS items (C5), where most male students achieved only the communication indicator, while female students met all indicators. In creating-type HOTS items (C6), both male and female students demonstrated achievement solely on the communication indicator.
