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

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

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
