This study describes high school students' reasoning profiles in solving logic problems based on impulsive and reflective cognitive styles. This research is a qualitative descriptive study. The subjects of this study consisted of one impulsive cognitive style student and one reflective cognitive style student. The supporting instruments used were the Matching Familiar Figure Test (MFFT) cognitive style test, interview guidelines, and problem-solving tasks (TPM). The data collection technique uses the problem solving task-based interview technique. Data analysis techniques using data reduction, data presentation, concluding / verification. The results showed that impulsive students solved the problem by changing the implication sentence from the question to the implication symbol, then making a truth table from the implication equivalence. Still, there were errors in writing the symbol of one of the statements. Next, the impulsive students wrote and mentioned the statement sentences obtained as a result of completion. Impulsive students provide reasons or evidence for one or several solutions by determining the second statement as an official statement and writing an example of an office sentence with universal and exponential quantor symbols. Reflective students solve problems by writing down what is known and what is asked from the questions, then underlining each statement, and marking it with a statement symbol. Then the students wrote the implication sentence with the implication symbol. Furthermore, the reflective students wrote down and mentioned the solutions obtained while circling the results obtained. With a tone of doubt, the students said the sentence "negation of implications in the form of symbols.

Cognitive process is a person's mindset in accepting, processing and representing the knowledge given by six agreed aspects; remember, understand, apply, analyze, evaluate and create. This research studies to describe the cognitive processes of students with independent and cognitive fields of cognitive style in solving mathematical problems. The subject of this study was one student with field independent and field dependent cognitive styles. The instrument used was the GEFT test, problem understanding test, and interview guidelines. The process of data analysis is done by triangulating data, presenting data and drawing conclusions. From the research results obtained by students with field independent cognitive style has more detailed characteristics in making explanations and being able to organize the information obtained and be able to save themselves from the development of the adjacent environment. Students with dependent cognitive styles tend to be only able to accept given concepts and are more global in providing explanations about the difficulties in the concept, besides students with dependent cognitive style are still needed by the surrounding environment.Cognitive process is a person's mindset in accepting, processing and representing the knowledge given by six agreed aspects; remember, understand, apply, analyze, evaluate and create.

One of the external factors that can affect student learning outcomes is the family environment, in this case, the attention of parents. Research has been carried out to determine whether or not there is an influence of parental attention on student learning outcomes in mathematics. This research is a quantitative study using the Ex-Post Fact method . Sampling was carried out using a probability sampling technique of the simpler random type which was carried out on 111 respondents consisting of class X and XI at SMK Khamas Asembagus. Data collection techniques used are observation, documents and questionnaires. The results showed that 0.237 > 0.1865 at Cronbach's Alpha = 0.1865, this indicates that the instruments used in this study are valid and reliable. Meanwhile, the results of the T test were 2.545 > 1.65895 (with ) and the Effectiveness of the Regression Line (EGR) was 3.25% which indicated that there was an influence of parental attention on student learning outcomes in Mathematics Subject of 3.25%. Based on the results of the analysis of research data, it can be concluded that the alternative hypothesis (Ha) is accepted and the null hypothesis (H 0 ) is rejected, meaning that there is an influence between parents' attention to student learning outcomes in Mathematics Subject which is equal to 3.25%.

This study aimed to describe the process of critical thinking of students in solving mathematical problems in algebraic viewed from the differences in cognitive styles-Verbalizer Visualizer. The description of the thinking process was based on Polya’s problem-solving indicator namely understanding the problems, developing plans, implementing problem-solving activities, and to re-examining the results obtained. The research instrument includes the researcher himself, tests of cognitive style, problem-solving task, and the interview guideline. The data analysis was performed by means of data reduction, data presentation, interpretation of data, and drawing conclusions. The study concluded that the visualizer subject disclosed the acknowledged information and asked to use the images and algebraic notation, used a variety of strategies to solve problems, performed calculations by taking into account the things we need and recheck the answer in detail. Verbalizer Subject, however, was able to disclose the acknowledged information and questioned using mathematics formula without using pictures and notation. In terms of making plans for the completion, the subject merely used one step-finishing process. In determining the final outcome, verbalizer subject rechecked every step of the finishing by recalling and paying attention to the proper answers

This study aimed to design a hypothetical learning trajectory for a two-dimensional figure area (quadrilateral and triangle) using the geometric shape of traditional food, tempe mendoan as a learning context. This research was qualitative research with data collection methods using literature studies, interviews, and documentation. The subjects in this study were seventh-grade junior high school students in SMP IT Nurul Fikri Bogor. The results of this study are in the form of a hypothetical learning trajectory design in learning the two-dimensional figure area through exploration of Banyumas food tempe mendoan, students measure each side of the rectangle from the shape of tempe mendoan, students divide the rectangle into square units as many as the results of each measurement side, students counts the number of unit squares that cover the rectangular area, the student finds the formula for the area of a square and a rectangle. Next, students divide one rectangle into two right triangles of equal size, students find the formula for the area of a triangle. Students attach the triangles to the provided two-dimensional figure shapes, students record the number of right triangles needed to cover each shape and find these relationships so that students can find area formulas for other shapes such as parallelograms, trapezoids, and rhombuses.
