This study aims to analyze the quality of mathematics learning after applying PjBL with project assessment on students' mathematical communication skills (KKM) and students' KKM in terms of self-efficacy in PjBL learning with project assessment. The type of research is a mix method with a sequential explanatory design. In this study, 6 research subjects were taken based on the level of self-efficacy in students of grade X-8 SMAN 6 Cirebon. The results showed that (1) the PjBL learning model with project assessment improved the quality of mathematics learning for KKM students, and (2) research subjects with high self-efficacy categories are able to meet all KKM indicators, namely stating problems into written mathematical ideas, stating mathematical problems in the form of drawings or mathematical models, presenting written mathematical problem solving in an organized and structured manner, and evaluating mathematical ideas in writing. Subjects with moderate self-efficacy categories were only able to meet the KKM indicators, namely expressing problems into written mathematical ideas and expressing mathematical problems into images or mathematical models. Subjects with a low self-efficacy category were only able to meet the KKM indicators, namely presenting written mathematical problem solving in an organized and structured manner, and evaluating mathematical ideas in writing.

This study aims to determine the application of the peer tutor method to the mathematics learning process of 5 deaf students in class X SMALB Negeri Slawi. The method used is the descriptive method. The data collection is done by testing, observation, and documentation. Data analysis was carried out by data reduction, presentation, and conclusion, which is the model of Miles and Huberman. Based on the results of data analysis, it can be concluded that peer tutors provide convenience for deaf students with below-average abilities in working on math problems. This is because deaf students get direction and assistance from deaf students who already understand and act as tutors so they can solve math problems. The application of the peer tutor method facilitates the learning process of deaf students. Students communicate with each other to assist, increase learning activity, and solve problems together it can affect the completeness of the learning outcomes of deaf students. In the learning process, peer tutors can be used as an alternatively appropriate and effective learning method, especially for deaf students.

The mathematical creativity of students in Indonesia is low. Students only imitate what the teacher does; if students are faced with a problem, they find it difficult to solve it. This study aims to determine the increase in students' mathematical creative thinking skills taught using the Creative Problem Solving model with a scaffolding strategy. The method used is pre-experimental, with one class serving as the experimental class for public junior high school 1 Batumarta VI students. The instrument in this study was a description of the test questions with the material on flat sides. The results of the study showed that there was a statistical increase in students' mathematical creative thinking abilities with the Creative Problem Solving model, which obtained an N-Gain value of 0,612 From this average value, 10 students were obtained in the high category and 16 students in the medium category and 3 students in low category

Good mathematical problem solving skills are important for students because they are the goals and principles in learning mathematics. However, various studies, both national and international, state that students' mathematical problem solving abilities in Indonesia are still low. The Geogebra-assisted discovery learning model is an innovation that can be used to improve students' mathematical problem solving abilities. This research aims to analyze the influence of the Geogebra-assisted discovery learning model on students' mathematical problem solving abilities in geometry learning. The research method used is meta analysis. The articles analyzed are articles sourced from Scopus, ScienceDirect and Google Scholar with a period of 2013-2023. Of the 10 articles analyzed, 3 of them studied groups of middle school students, 4 groups of high school students, and 3 students. The results showed that 8 articles had a large effect size, 1 article was a medium size, and 1 article was a small size. The results of the Independent Sample t-test obtained tcount of 11.59 and ttable of 1.96. So it can be concluded that the discovery learning model assisted by Geogebra has an effect on students' mathematical problem solving abilities in geometry learning. Through the discovery model, students discover their own concepts and solve the problems. Geogebra is important for illustrating geometric problems. Future research can also analyze the extent of the influence of the Discovery Learning model assisted by Geogebra on students' mathematical problem solving abilities in terms of various other variables both from within the students and from the surrounding environment.

Mastering algebraic concepts and skills has been one of the demands in the Indonesian curriculum for the past few decades. Teaching algebraic concepts and skills is one of the materials taught from the junior high school to university level. Therefore, it is mandatory for pre service mathematics teacher students to master and even fluently use algebraic concepts in order to develop students' algebraic thinking skills. Thus, this study aims to understand and obtain a description of students' algebraic thinking abilities and misconceptions in solving problems. This research using descriptive qualitative. Analysis was conducted using tests and in-depth interviews with students who had taken linear algebra courses in semester 3 of the Mathematics Education Study Program at private university in NTT. Student’s algebraic thinking skills in solving problems were analyzed using Kieran's (2004) indicators consisting of: generational activities, transformational activities, and global meta-level activities. The results of the research show that…. In generational activities, students in the low, medium, and high categories have misconceptions. In transformational activities and global meta-level activities, misconceptions are only carried out by low category students.

This study aims to compare mathematics curricula in Indonesia and Malaysia based on the TIMSS (Trends in International Mathematics and Science Study) framework. The main focus of the study is to identify differences in content and cognitive domains reflected in the two curricula, as well as to analyze the extent to which the curricula accommodate higher-order thinking skills (HOTS). Using qualitative methods, including curriculum document analysis and interviews with teachers in Indonesia, this study found that the Malaysian curriculum is more structured and emphasizes reasoning and applying skills in real-world contexts, by the TIMSS indicators. In contrast, the Indonesian curriculum, although starting to integrate HOTS elements through the Merdeka Curriculum, still faces challenges in implementation and gaps in teacher training. These differences reflect the readiness of each country to prepare students to face global challenges through relevant mathematics learning. The results of this study provide important insights for curriculum development in Indonesia and can serve as a reference for policymakers to align the curriculum with international standards. This study provides important insights for curriculum development in Indonesia, as well as recommendations for policymakers to further align the curriculum with international standards, strengthen teacher training, and integrate applied elements in mathematics learning to achieve more optimal results in international evaluations such as TIMSS.
