Students' mathematical communication skills viewed from mathematical resilience in probing-prompting learning with performance assessment
No full textBy evaluating students’ performance in their mathematical communication skills and characterizing those skills in terms of their mathematical resilience, this study seeks to determine the efficacy of probing-prompting learning. A mixed method by using a sequential explanatory research design is employed. The study was conducted in two phases: first, quantitative data was collected and analyzed, then based on the findings of the quantitative data, qualitative data was collected and analyzed. The results of the research show that (1) the probing-prompting model with performance assessment is effective to improve students' mathematical communication skills and mathematical resilience and (2) based on the analysis of mathematical communication skills regarding students' mathematical resilience, it shows that students who have low stage of mathematical resilience are only able to express one indicator of mathematical communication skills, while students who have moderate and high stages of mathematical resilience are able to express five indicators of mathematical communication ability. The conclusion is probing-prompting learning with performance assessment can be used to improve students' mathematical communication skills and based on students’ mathematical resilience, students also have different levels of mathematical communication skills

The effect of group investigation model of learning on improving mathematics learning outcomes
No full textThe instructional model is a crucial component in the educational process. This study evaluates the effectiveness of the Group Investigation learning model in enhancing students' mathematics outcomes. A quantitative research method with a One Group Pretest-Posttest design was used, involving 29 eighth-grade students. Data were analyzed using SPSS version 25, revealing a pretest score of 0.010 and a posttest score of 0.063 after implementing the Group Investigation model. The average posttest score was 77.91, indicating a significant impact on learning outcomes. Observations over three sessions showed an increase in student participation from 26.97% with an average score of 2.24 in Session I (categorized as "Less Active") to 42.79% with an average score of 3.56 in Session II, and 45.38% with an average score of 3.78 in Session III (both categorized as "Active"). This increase demonstrates that the Group Investigation model not only enhances student participation but also makes students more active in learning, thereby improving mathematics outcomes. Therefore, the Group Investigation model is an effective strategy for enhancing students' achievement in mathematics. Further research with more refined methods and tools is needed to confirm these findings
Effectiveness of AI in solving math problems at the secondary school level: A comparative study with student performance
No full textThe research aims to evaluate the effectiveness of artificial intelligence (AI) in solving mathematical problems at the high school level by comparing the performance of AI with that of students. Utilizing the ChatGPT tool and a dataset of 20 mathematics questions from the high school curriculum, the study involved ten students from the Muhammadiyah Mertoyudan Islamic Boarding School. The results indicate that AI exhibits high accuracy in multiple-choice questions (98%) and short-answer questions (95%), albeit with a decrease in performance for essay questions (75%); conversely, students demonstrated an average accuracy of 85% for multiple-choice questions, 80% for short-answer questions, and 70% for essay questions, additionally, also demonstrated higher consistency, particularly in questions requiring complex conceptual understanding. At the same time, the findings underscore the significant potential of AI as a tool for mathematics learning, further development is needed to enhance its ability to comprehend and respond to essay questions, thereby improving conceptual understanding and critical reasoning. The implications of these findings can contribute to the advancement of more sophisticated and effective educational technology to support mathematics learning in schools
