This study aims to analyze and describe the relationship between basic mathematical abilities and statistical learning outcomes. This study is an explanatory researchs with quantitative correlational research method. The subjects in this study were fifth semester students of the D3 Corporate Management study program, while the objects in this study were students' basic mathematical abilities which included algebra, calculus, and probability and student statistics learning outcomes. The data was collected using a basic mathematical ability test instrument consisting of a test of algebra, calculus and probability material as well as a test of statistical learning outcomes. The data obtained were analyzed by descriptive and inferential statistics. Inferential statistical testing using multiple linear regression test. Based on the results of data analysis, there is a positive relationship between basic mathematical abilities (algebra, calculus, and probability) on student statistics learning outcomes.

Factors that affect students' mathematics learning outcomes include the lack of student interest in mathematics. Learning that does not have meaning and the teacher's teaching methods are still less diverse, causing a lack of student interest in learning mathematics. One of the meaningful learning is when students can make their own notes from their understanding while studying. This study aims to determine the differences in mathematics learning outcomes of students who are taught using the mind map method and students who are taught with the concept map method. This research was conducted at a private senior high school in Medan. This type of research is a quasi-experimental research design using randomize pretest-posttest control group design. The sampling technique uses purposive sampling by taking two experimental classes in class X high school. The instrument used to determine student learning outcomes on exponent material is a test in the form of an objective test of 15 items that have been declared valid and reliable. The results showed that the average student learning outcomes taught using the mind map method were higher than those taught with the concept map. From the results of this study teachers are expected to use the mind map method to improve student mathematics learning.

The purpose of this study was to describe students' communication in solving prime factors using written and oral communication. This study uses a qualitative and descriptive approach. The subjects of this study were 46 seventh grade students of Simanjaya Lamongan, East Java, Indonesia, Middle School who had obtained prime factor material. Data analysis was obtained by using a test of prime factors and interviews. Based on the results of data analysis, it was concluded that: 1) Written communication, as many as 40 students were able to communicate in writing with a percentage of 87% and 6 students were unable to communicate in writing with a percentage of 13%; 2) Oral communication, at this stage interviews were conducted by taking the subject as many as two students taken from one student who is able to communicate in writing and one student who is not able to communicate in writing, the results obtained that students are able to communicate in writing are also able to communicate verbally. verbally, while students who are not able to communicate in writing, it turns out that students are able to communicate orally. From the explanation above, it can be concluded that students are able to explain concepts into mathematical language, students are able to explain mathematical arithmetic operations, students are able to explain mathematical solutions and students are able to convey ideas or opinions. Thus, students can communicate in writing and orally well in solving prime factors.

This study was motivated by the transformation of the learning process from face-to-face to online learning due to the Covid-19 pandemic. This study aims to analyze students' online learning readiness in the Covid-19 pandemic era regarding statistics learning outcomes. This research is a quantitative descriptive study using a regression research design. Data collection was carried out by providing online learning readiness questionnaires and statistical material tests to students. Based on the results of data analysis, it was found that there was a relationship between online learning readiness and student learning outcomes statistics, with the acquisition price of Fcount = 4.195 and a significance value of 0.048 <0.05, and 46.1% of student statistics learning outcomes were influenced by learning readiness and the rest was influenced by external factors. student learning readiness. Based on these results, it is concluded that online learning readiness affects student learning outcomes statistics, where the large influence of learning readiness is 46.1%. Therefore, so that lecturers and students can maximize factors outside of learning readiness so that the achievements and objectives of the statistics course can be maximally achieved even though learning is carried out online.

In solving the problems they face, students must think so that they can apply the right concepts to the problems they face. This process can run effectively in learning if students have good reflective thinking skills. Mathematical reflective thinking is one of the thought processes needed in the process of solving mathematical problems. The purpose of this study was to determine the increase in reflective thinking skills between students who received learning with problem-based learning and conventional learning. The research method used is quantitative research with a quasi-experimental design. The population of this study was students of grade 7 MTs Islmaiyah Medan in the academic year 2019/2020. The sample in this study was students of class 7-A and 7-B MTs Islamiyah Medan. The data were collected by giving a reflective thinking ability test instrument. The data obtained were analyzed using a two-way ANOVA statistical test. Based on the research findings, it was found that there was an increase in students' reflective thinking skills taught by problem-based learning with students taught conventionally. Where the increase in reflective thinking skills between students whose learning process using problem-based learning is significantly higher than students whose learning is through conventional learning. Based on these results, it can be concluded that in an effort to foster students' mathematical abilities, the learning model used must match the characteristics of the learning model with mathematical abilities.

Problem-solving is one of the mathematical skills needed by students and plays an important role in helping them achieve conceptual understanding in learning mathematics. On the other hand, self-efficacy is also important because it relates to a person's belief in his ability to complete a task or achieve a goal. Based on this, this study aims to examine the relationship between self-efficacy and problem-solving abilities. To achieve the research objectives, the quantitative correlational method was used in this study. Data collection used a survey method to obtain data self-efficacy and students' mathematical problem-solving abilities. Data analysis was performed using inferential statistical analysis to prove the research hypothesis. Hypothesis testing includes analysis of correlation, regression, and coefficients of determination. Based on the results of the study, it can be concluded that there is a moderately positive relationship between self-efficacy and problem-solving abilities. where self-efficacy contributes to problem-solving abilities by 27.8%.
