The first problem faced by students is the ability to represent AMT when learning mathematics. In Indonesia, mathematics is a subject that is less popular with most students because it is complicated and difficult to understand. Mathematical material and mathematical thinking skills are two things that continue to develop, namely between mathematical material that is understood and students' mathematical thinking skills that need to be further developed through mathematics learning and mathematical material that continues to be developed more widely. This study aims to compare several AMT learning strategies for students. This study can improve the abilities that students already have to be better. Especially the development of mathematical abilities in students, one of which is AMT ability. Therefore, in learning mathematics, it is necessary to develop students' AMT abilities. The research method used in this study is descriptive analysis. This study also uses a Randomized Pretest Posttest Control Group Design research design. The results of experimental research on the effect of learning strategies on students' AMT abilities. The use of cooperative learning in learning activities in schools has various advantages or benefits. Strength is oriented towards optimal learning activities so that learning objectives can be achieved effectively through the support of lecturers and students in learning. In addition, the selection of learning strategies used by lecturers is greatly influenced by the nature of the subjects to be taught and is also influenced by the level of AMT ability that already exists in students.

Learning discrete mathematics, particularly on the topic of equivalence in propositional logic using propositional algebra laws, often presents challenges for students due to its abstract nature and the logical thinking skills required. This study aims to analyze the effectiveness of using ChatGPT as a learning aid to enhance students' understanding of this topic. The research employed a quantitative method with a post-test only control group design, involving two groups of students: an experimental group using ChatGPT and a control group utilizing conventional learning methods. Data were collected through a post-learning achievement test. The results showed that the average score of the experimental group (85.47) was significantly higher than that of the control group (66.78). The independent t-test results yielded a significance value of < 0.05, indicating a significant difference in learning outcomes between the two groups. Furthermore, the calculation of Cohen's d showed a value of 0.959, categorized as a large effect size. These findings indicate that the use of ChatGPT as a learning aid has a significant impact on students' learning outcomes. With its interactive and responsive features, ChatGPT helps students grasp complex propositional logic material more easily. This study recommends utilizing AI-based technologies like ChatGPT as an innovative learning strategy, particularly for abstract topics in discrete mathematics.

The study focuses on the influence of the Multiply Cards learning media on the mathematics learning outcomes of fourth-grade students at SD Negeri Beroanging. The main issue in this research is whether the Multiply Cards learning media affects the mathematics learning outcomes of fourth-grade students at SD Negeri Beroanging. This research is a quantitative study using an experimental method with a "One Group Pretest Posttest Design." The research population consists of all fourth-grade students at SD Negeri Beroanging. The sampling technique employed is probability sampling, specifically cluster random sampling, where the sample is randomly taken from classes IV A, B, and C at SD Negeri Beroanging. Consequently, the sample obtained is class IV B, consisting of 31 students, comprising 18 girls and 13 boys. Data collection is conducted through testing and observation techniques. The collected data is analyzed using descriptive and inferential statistical analysis.Based on the data analysis results, the effect of the Multiply Cards learning media on the mathematics learning outcomes of fourth-grade students at SD Negeri Beroanging is found to be 5.23. This calculated t-value (tHitung) can be compared with the table t-value (tTabel) for db = N-1, where N=31, thus db = 31–1 = 30 at a significance level of 0.05. The tHitung = 5.23 and tTabel = 1.697. Therefore, tHitung > tTabel. The comparison of the pretest and posttest results indicates that the tHitung value of 5.23 is greater than the tTabel value of 1.697. This shows that the proposed research hypothesis is accepted. The hypothesis is tested using a t-test statistic, indicating that the use of the Multiply Cards learning media has a significant effect on the mathematics learning outcomes of fourth-grade students at SD Negeri Beroanging.

This study aims to describe and reveal data about the diagnostic approach in assessing learning difficulties in junior high school students.

Numeracy is not only the responsibility of mathematics teachers, but also the responsibility of all non-mathematics teachers, namely teachers who teach subjects other than mathematics. The approach needed is cross-subject numeracy. Based on the results of interviews with partner schools, it was obtained that teachers in these schools still have minimal knowledge about numeracy literacy and numeracy reinforcement in non-mathematics lessons. The solution offered is to provide reinforcement of numeracy literacy materials and provide reinforcement of non-mathematics or cross-subject numeracy literacy materials so that non-mathematics teachers can also improve students' numeracy in subjects other than mathematics. The implementation mechanism consists of 3 main stages, namely the planning stage, the implementation stage, and the evaluation stage. Evaluation of program implementation is measured from the increase in participants' knowledge from pretest to posttest and the participant's response questionnaire to this activity. Based on the results of the community service, it can be concluded that this activity makes a good contribution to increasing the knowledge and understanding of SMP Terpadu Darul Dakwah teachers regarding cross-subject numeracy literacy and examples of learning activities to strengthen numeracy literacy in subjects other than mathematics. The number of participants who experienced an increase in score from pretest to posttest was 100%, meaning that all participants in the activity experienced an increase in knowledge. In addition, it can also be seen from the average pretest of 48 and the average posttest of 75.5. The overall process of implementing this activity went well and smoothly.

Education is a learning process aimed at developing individual potential in cognitive, affective, and psychomotor aspects, enabling them to contribute optimally to society. In formal education, such as in schools, various disciplines are taught, including mathematics, which helps students think logically, analytically, and solve problems. Mathematics education is expected to help students understand concepts that can be applied in various fields of science and real-life situations. Students should understand mathematical concepts, recognize relationships between concepts, derive formulas and properties, perform mathematical operations for generalization, gather evidence or explain ideas and mathematical statements, solve problems, use mathematics to communicate ideas, explain situations or problems, and appreciate the importance of mathematics in their lives. Conceptual understanding represents the lowest level of the cognitive domain and is a crucial learning objective as it provides the understanding that the lessons taught are not merely about mathematics. The conceptual understanding of mathematics among the 24 students in class XI at SMK RPI Jakarta resulted in an average score of 76.9. This indicates that the majority of students have a good understanding of the concepts, although some still require improvement..
