This article aims to determine the effectiveness of Class Wide Peer Tutoring (CWPT) implementation to improve students' mathematical reasoning abilities. This research is experimental research with a mixed-method approach. The research sample was determined through cluster random sampling. Data were collected through mathematical reasoning tests arranged according to indicators of mathematical reasoning ability. Data were analyzed using inferential statistics with the stages of normality, homogeneity, and hypothesis testing. The result shows that the implementation of CWPT enhances students' mathematical reasoning on Equations and Inequalities of an Absolute Value. Mathematical reasoning test results show that the 10th grader score of mathematical reasoning is 76.75 (Good). The indicator of mathematical reasoning that is the most difficult for students to master is "drawing logical conclusions" with the acquisition of a mathematical reasoning score of 35.81 (poor), while the easiest mastered by students is "Presenting mathematical statements or premises in writing, drawings or graphics" with mathematical reasoning score of 80.14 (Very Good). The students' mathematical reasoning ability on the indicator "compiling an analogy or explanation of the problem and its solution" is 74.09 (Good). The mathematical reasoning ability of students on the indicator "mathematical manipulation" is 42.10 (fair). Keywords: Mathematical Reasoning, Students’ ability, Class Wide Peer Tutoring

Statistics has been a compulsory subject in many study programs, considering its importance as a provision for university students to conduct research, which is one of the requirements for graduation. However, statistics anxiety, which hurts statistical competence, is a common phenomenon in students. This study, first, aims to describe students' statistics anxiety. It also wants to examine whether gender differences are also a cause of this statistics anxiety. The study took 167 samples of students at a university in Central Java, Indonesia. They were selected by simple random sampling. The statistics anxiety scale has been tested for its validity and reliability and becomes the instrument in this study. This study found that the majority of students' statistics anxiety was on average at a moderate level. It also found no difference in statistics anxiety based on gender, seen either as a whole or in terms of each domain. Further related research is expected to examine statistics anxiety with a qualitative approach or mixed methods to describe its nature and causes in more depth, as well as efforts that can be made to reduce such anxiety. Keywords: statistics anxiety, gender, interpretation

Two factors that cause creative thinking does not develop during education are the curriculum and educators, which are generally designed with a broad target, so that educators focus more on completing the material. In this case, it is known that mathematics learning that has occurred so far has not been able to attract students' attention, especially in creative thinking. This study aims to improve students' creative thinking skills with the Treffinger learning model. This study uses a mixed method (a combination of quantitative and qualitative methods). This research was conducted in class VII MTs SA Al Istiqomah on the material of triangular and quadrilateral shapes. These students of MTs Sa Al Istiqomah Mojosari class VII total of 15 students. The research sample amounted to 2 students who were selected using a sampling technique. In addition, one student with high post-test or high scores (SNT) and one low-scoring student (SNR) will be interviewed. The indicators of creative thinking used in this study are indicators (1) Fluent, (2) Flexible, (3) Original, and (4) Detailed. The results showed that students with low scores and high scores overall were included in the category of students with high creative thinking abilities because more than 85% of students met the criteria for high creative thinking abilities. This was evidenced by the fulfillment of all indicators of creative thinking abilities. However, there are still some students whose scores are below the average. This is evidenced by students only being fluent and flexible, which means that the original and detailed indicators have not been met. Keywords: Creative Thinking, Two Dimensional Figure, Treffinger.
