One learning approach that can be applied to learning mathematics is reciprocal teaching because it is efficient in helping students become independent learners and developing students' courage in expressing opinions. Many studies have discussed Reciprocal Teaching with mathematics learning outcomes in primary and secondary schools with different conclusions. This study aimed to determine the effect of the Reciprocal Teaching model on students' mathematics learning outcomes. This study used a meta-analysis, a statistical analysis method that synthesizes data from several studies to obtain stronger findings. The sample in this study were articles that met the inclusion criteria and obtained as many as 8 articles. Data were analyzed using JASP V-0.18 software. The results showed that the Reciprocal Teaching model affected students' mathematics learning outcomes, with an effect size of 1.07 and a high effect size category. However, this analysis did not include some related studies because they did not meet the inclusion criteria. Therefore, further research using a larger sample size and a wider variety of studies is needed to gain a more thorough understanding.

Mathematics is essential as it forms the foundation for sciences applied in the real world. Students' success in learning mathematics is crucial and must be prioritized. To understand and excel in mathematics, diligent study is required. Students who study diligently are often motivated by external factors such as outcomes, targets, environment, and teachers. Enthusiasm serves as the driving force that fosters the desire to learn effectively. Thus, motivation is a critical and consistent factor that encourages students to study diligently, ultimately improving their mathematics learning outcomes. This study examines the influence of school origin, national exams (UN), and tutoring on students' motivation to learn mathematics. The research involves a preliminary study, data collection, and analysis using a decision tree with the help of the Orange application. The results indicate that high motivation levels are more common among students attending public schools and those influenced by the presence of national exams. The findings of this study should be utilized by the government to enhance students' learning motivation and significantly improve mathematics learning outcomes. The study suggests targeted actions, including equitable resource allocation, alternative evaluation systems, teacher training, and enhanced counseling services, to effectively boost students' learning motivation and improve the overall quality of education. This research contributes by providing empirical evidence on the factors influencing students' motivation to learn mathematics, offering insights that can inform policies and interventions aimed at fostering a more effective and engaging learning environment.

The objective of this study is to determine students’ learning barriers in understanding integral concepts through their thinking processes with the perspective of APOS theory (Action, Process, Object-Scheme). This research applied qualitative research with a case study method. The samples of this research were 19 civil engineering students who had contracted calculus courses and who had been given a written test. The results of the written test were divided into three different categories – they are comprehension ability is high (score ), medium (60 Score < ) and low (score < 60). Deep interviews were conducted with three representative students who took the written test and met the criteria for each group. The results of the interviews showed that students in the high category still had conceptual ontogenic learning obstacle despite passing the APOS path. Students in the moderate category be able to reach the encapsulation stage but they had not been able to de-encapsulate it to the process. They had conceptual and epistemological ontogenical learning obstacles. Whereas the low category students had the tendency to only reach the action stage and had difficulty in doing initial de-encapsulation due to lack of learning experience in the prerequisite materials. The learning obstacles they experienced were psychological and conceptual-ontogenical learning obstacles. Aggregately, the students tended to experience conceptual ontogenic learning obstacle. The result of this study is expected to be used as a basis for designing a hypothetical learning trajectory in future research.

The objective of textbook study is to create high-quality textbooks. Analysis was done using a praxeological-didactical analysis (PDA) method. PDA offers space to analyze curriculum materials, such as math textbooks, which are the outcome of human action in the anthropology of a specific nation's society. There are 10 types of tasks given in the mathematics textbook on measurement of spatial figures and seven techniques are identified as possible ways to complete the tasks. The justification of praxis is that there are three emerging technologies and two theories that are used as the final direction of the given task type. There is a sequence of task composition at the start with loads at level 2 and level 3 that can affect student readiness. Psychologically, it is regarded as difficult at first, which can lead to students becoming disinterested as well as bored, thus experiencing difficulties, creating ontogenetic obstacles. The other predicted learning obstacles identified in this textbook are epistemological and didactic obstacles. All the findings from this analysis can be applied to continuously raise the standard of the currently available mathematics textbooks.

This study aims to determine students learning obstacles in probability material based on their probabilistic thinking (PT) level using the theory of didactical situation (TDS) perspective. This is qualitative research with the case study method. The subject consisted of 23 grade 9 students in junior high school who had studied the material and had taken the test. The test results were used to classify students depending on their PT level using the framework developed by Graha A. Jones. Furthermore, interviews were performed with three representative students from each PT level. The interviews indicated that students in each PT level continue to face learning obstacles, which include instrumental ontogenic and epistemological obstacles. The lowest PT level demonstrated a more complex and comprehensive learning obstacle in all constructs of PT. From the TDS perspective, all students who are at various levels of PT have reached an action situation. Only 33% of the students at the subjective level and 83% of the students at the transition level reached the formulation situation. Still, students at that level needed help to reach the other two situations. Unlike the two previous levels, students at the level of quantitative informal thinking can achieve situations of validation and institutionalization.

Mathematical abstraction as part of mathematical thinking process is an important and fundamental process in mathematics and its learning. Pre-service mathematics teachers' experiences and sentiments towards mathematical abstraction can contribute to the way they teach in the future. This study involved 67 Pre-service Mathematics Teachers at one of the Universities in Central Java Province who aimed to analyze their sentiments towards mathematical abstraction problems. The data collection technique used a questionnaire to reveal the Pre-service Mathematics Teacher's response to abstraction problems. Sentiment analysis is used to analyze the responses given which are categorized into positive, negative, or neutral. The technique used in the research is Naïve Bayes Classifier Multinomial. The classification results show 62.9% negative sentiment, 24.2% neutral sentiment, and 12.9% positive sentiment. In addition, the model evaluation results show an accuracy value of 66.7% which indicates the reliability of the model in classifying the sentiments expressed by Pre-service Mathematics Teachers towards mathematical abstraction problems. Pre-service Mathematics Teacher sentiment towards mathematical abstraction problems is dominated by negative sentiment. This shows that the process of mathematical abstraction is still considered a complicated and confusing process.
