Abstract

This study describes students' cognitive in solving Pythagorean theorem problems in terms of gender. The research design used is explorative with a qualitative descriptive approach. The research subjects selected were 2 students, namely 1 male student and 1 female student. Data collection was carried out using written assignments and interviews. Checking the quality of the research results using data credibility is done by extending involvement, increasing persistence, discussions with peers, and membercheck and dependability. Data analysis techniques used in this research are data condensation, data display, and conclusion drawing and verification. The results showed that male and female students had raised all commognitive indicators. Male and female students can generally bring up keywords in the form of the words "area of a right triangle 25 ", "perimeter = K", and "hypotenuse c in k". Male students wrote very brief information while female students wrote clear and complete information. The description of the solution written by male and female students is different. The differences found were the use of visual mediators such as visualizing. Male students generalized a as height, b as base, c as hypotenuse while female students generalized a as base, b as height, c as hypotenuse. Endorsed narratives carried out by male and female students can write the formula for the hypotenuse of the Pythagorean theorem, the formula for the area of a right triangle, the formula for the perimeter of a right triangle and the factoring formula. Male and female students can also express the definition of the formula in solving Pythagorean theorem problems. Routines performed by male and female students can choose the right concepts and methods so that they have a good effect on the results of their solutions.       Keywords: commognitive, pythagorean theorem, gender. DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1839-1853

Abstract

Students' errors in solving mathematical problems need to be analyzed in depth so that teachers can choose the right way to anticipate the repetition of the same errors. This study aims to reveal the types of errors made by students in solving word problems on the topic of proportion. This study is a descriptive study with a qualitative approach. The subjects involved were two seventh grade students, male and female. The results of this study indicate that based on Newman's error analysis, male subjects mainly made reading errors, errors in understanding the problem, transformation errors, and writing the final answer that did not include a conclusion. While female subjects made errors in understanding the problem, choosing the operation used, and writing the conclusion sentence in the final answers. The results of this study can help students understand the errors made so that the errors are not repeated and can be input for teachers in improving the learning process.

Abstract

This article contains an exploration of conceptual understanding in geometry lectures in the Elementary School Teacher Education Study Program, Cokroaminoto Palopo University, Odd Semester, Academic Year 2020/2021. This research was conducted through a qualitative approach with the aim of explaining the details of the relationship between concepts in detail and recommending appropriate learning in problem solving. Data were collected using observation, documentation, and written tests. The three techniques are elaborated with the aim of analyzing the concepts and problem-solving patterns of the students' final semester test results. The results of the study explain several findings, namely, Teaching geometry should begin with the process of identifying the important concepts that build up a particular problem. These concepts are then analyzed and linked to one another to form a network. The concept network is then represented in an image/visual display. Through this visual display, lecturers can guide students in compiling procedural steps based on the sequence of concepts that have been compiled. Lecturers need to create meaningful learning for students by connecting previous knowledge with new knowledge through various representations, examples, and manipulations and focus on conceptual understanding rather than procedures or rules.Eksplorasi Pemahaman Konsep Geometri MahasiswaArtikel ini memuat eksplorasi pemahaman konsep dalam perkuliahan geometri pada Program Studi Pendidikan Guru Sekolah Dasar Universitas Cokroaminoto Palopo Semester Ganjil Tahun Akademik 2020/2021.

Abstract

Digital visualization of mathematical concepts makes it difficult for students to learn and this results in a lack of understanding and participation of students. This study aims to analyze the needs of developing worksheets in flat analytical geometry courses for students of the mathematics education study program. The method used is qualitative research. On the worksheet there is an exploration of three-dimensional shapes on flat analytical geometry, practice questions created using the features available on GeoGebra. Data is collected through written tests and interviews with course lecturer students. The data is then analyzed descriptively quantitatively to determine student knowledge related to the material contained in GAD. From the results of the analysis, it was obtained that students had low scores on knowledge In addition, the results of interviews with lecturers who teach GAD courses also showed difficulty in conveying an understanding of 3D images. For this reason, digital worksheets that can help students to visualize the two- and three-dimensional builds in the GAD course are very necessary.

Abstract

The aim of this research is to obtain a description of the mathematical communication ability profile of MAN SIGI students in solving sathematical problems in view of visual learning style. This type of research is descriptive with a qualitative approach. The subjects of this research were students of class XII IPA 1 MAN SIGI who had a visual learning style. Characteristics of the visual learning style are the ability to remember information seen and prefer reading to listening to other people's explanations. Determining the subject in this research, prospective researchers gave a learning style questionnaire consisting of 10 questions, and each question had 3 choices: a, b, c. If a student most dominantly chose a, then the student had a visual learning style; if a student most dominantly chose b, then the student has an auditory learning style; if a student chooses a lot of c's, then the student has a kinesthetic learning style. Based on the results of the questionnaire, 1 student was selected with a visual learning style. If there were several students who had a visual learning style, the researcher discussed with the study teacher about students who had good communication skills and students who received information easily. Data was collected through written tests and interviews. The results of this research showed that the subjects with a visual learning style are able to write down and explain well all the information obtained from the questions.
