This research aims to determine whether there is a relationship between mathematics learning outcomes and physics learning outcomes by taking the subject of exponent numbers in mathematics and the subject of temperature and heat in physics. This research was conducted on class X students at SMA Negeri 6 Tangerang in the second semester. The sample was taken at simple random (cluster sampling) by taking one class from nine existing classes with a total of 30 students. The method used is a survey method with correlation techniques. The independent variable in this research is the results of learning mathematics, while the dependent variable is the results of learning physics. Before the data is analyzed, the requirements test is first carried out, namely the normality test using the Lilliefors test and the regression significance test using analysis of variance (ANOVA). From the results of the normality test for the independent variable, it was obtained that L-count = 0,08770 < 0,161 = L-table, while for the dependent variable it was obtained that L-count = 0,1108 < 0,161 L-table, so it can be concluded that the two samples were normally distributed. The results of linear regression calculations are obtained  The linearity test obtained F-count 1,067 < 2,45 = F-table so it can be concluded that the regression model is linear, meaning there is a linear relationship between the two variables. The regression significance test obtained F=count = 34,732 > 4,20 = F-table. This means that the regression model is significant. Hypothesis testing was carried out using product moment correlation analysis, then calculating the significance of the correlation using the student t-test. The results of the correlation coefficient calculation obtained r-count = 0,744 and the results of the t-student test calculation obtained t-count = 5,892, while the t-table value with a significance level of  α=0,05 and degrees of freedom (dk) = 28  was 2,05. Because t-count = 5,892 < 2,05 = t-table means Ho is rejected. So the results of this research conclude that there is a relationship between mathematics learning outcomes and physics learning outcomes. The coefficient of determination (r2) was obtained at 0,554. This means that mathematics learning outcomes contribute 55,4% to physics learning outcomes.

In mastering mathematics—which requires reasoning, analysis, and systematic review—critical thinking is essential to address the challenges of the 21st century. This research employs a quasi-experimental design using a pretest-posttest control group model. The subjects of the study were eighth-grade junior high school students, divided into an experimental group and a control group. The main instruments used were a mathematical critical thinking skills test and a learning activity observation sheet. The findings indicate that students who participated in instruction based on a deep learning approach showed a significant improvement in critical thinking skills compared to those who received conventional instruction. Unlike students who underwent standard learning methods, those exposed to deep learning strategies experienced a notable enhancement in their critical thinking abilities. Based on these findings, the implementation of deep learning is recommended more broadly in mathematics classroom instruction.

This research aims to explore the ways in which teachers address the challenges of learning mathematics for children in primary schools by referring to behavioristic theory. This theory emphasizes the central role of stimuli and reactions in influencing learning behavior, and the application of both positive and negative reinforcement to improve students' motivation and understanding. The approach adopted was a descriptive qualitative method using case studies in various primary schools. The results indicated that behavior-focused methods, such as providing repeated practice of problems, immediate feedback, use of concrete tools, and regular application of rewards and punishments, can improve students' enthusiasm and mathematics learning outcomes. However, teacher-driven learning and lack of innovation are barriers to implementation. Therefore, a combination with other methods is needed to make the learning process more thorough.

Dyscalculia is a specific learning disorder that affects students' ability to understand basic math concepts. Handling this condition requires the active role of the teacher as the main facilitator in the learning process. This study aims to describe in depth the role of teachers in handling students with dyscalculia at SLB Yasmin Sumenep, and highlight the importance of coordination patterns between teachers and parents in supporting students' learning success. Using a qualitative approach with a case study method, data was obtained through observation and in-depth interviews with teachers. The results show that teachers not only function as teachers, but also as motivators and emotional companions for students. Teachers apply concrete and fun learning strategies, and create a supportive classroom atmosphere. In addition, the communication pattern between teachers and parents through a special group is an important factor in monitoring children's development and developing appropriate learning solutions. So, the role of adaptive, collaborative and empathic teachers determines the effectiveness of mathematics learning for students with dyscalculia. This study emphasizes the importance of continuous teacher training and strengthening the synergy between school and family to realize inclusive education.

Assessment of learning outcomes plays a crucial role in evaluating students' academic achievement. Midterm and final exam scores are often used as benchmarks for learning performance, yet the relationship between the two is rarely analyzed in depth. This study aims to examine the correlation between Midterm Exam (UTS) and Final Exam (UAS) scores in Mathematics among 11th-grade students at Bhakti Kencana Vocational High School in Bandung. A quantitative approach with a correlational method was employed, involving 30 students as the sample. Data were obtained through documentation of scores, and analysis was conducted using the Spearman Correlation Test due to the data not being fully normally distributed. The results indicated a significant and positive correlation between UTS and UAS scores, with a correlation coefficient of 0.511. This suggests that midterm scores can serve as a fairly reliable indicator of final exam performance and reflect the consistency of students' academic performance. The implications of these findings highlight the importance of continuous monitoring and learning efforts from mid-semester onwards to optimize students' final outcomes.

The results show that Quizziz can be used as a useful learning tool to encourage students to learn more. This study found that Quizziz can increase students' motivation and have a positive effect on their learning outcomes.

This study aims to analyze students' difficulties in understanding algebraic concepts in the implementation of the Merdeka Curriculum. This type of research uses a descriptive research method with a qualitative approach. Data collection techniques include interviews, questionnaires, and three written tests. Based on the results of interviews and questionnaires conducted by teachers with the school principal and mathematics teachers, the school has implemented the Merdeka Curriculum despite limitations in resources. The Merdeka Curriculum contributes to teachers in terms of teaching modules and freedom in creativity in learning, although training is still needed. The results of the student questionnaire indicate that the majority of students have difficulty understanding algebra, especially in identifying variables, but the majority of students feel that classroom learning is interactive and enjoyable. Most students feel helped by the example questions provided by the teacher. The written test results show that students have difficulty with the use of positive and negative signs, coefficients, constants, algebraic operations, and determining variable values. This indicates that the majority of students have not yet achieved mastery of the algebra material. It can be concluded that the implementation of the independent curriculum at SMP IT Az-Zahira Khatulistiwa supports teachers in the algebra learning process through the use of teaching modules, but students still struggle to understand algebraic concepts due to the limited use of educational media, which is constrained by the school's facilities.
