Abstract

The aim of the research is to summarize the experiences of grade 11 students at SMA Negeri 4 Palu based on Newman's theory. This type of research is descriptive, using a qualitative approach. The research subjects were two students selected from 35 class XI students. The findings of this research are as follows: (1) Not a single subject experienced errors in reading the lesson material, because at that time every subject was considered able to read the lesson material correctly. (2) Not a single subject made a mistake in understanding, as seen in the interview phase. All research subjects were able to provide understandable and questionable information regarding the subject. (3) Each research subject carries out transformation error correction. This transformation error is characterized by the failure of a subset that reduces the problem of the mathematical model. (4) Process skills errors were made by each research subject. This is explained by the subject's understanding of the steps taken in answering the question, but most of it is caused by the subject's errors occurring in the transformation step and the subject being unable to solve mathematical problems accurately. (5) an error in writing the final answer (encoding error) was made by each research subject; This is differentiated by the fact that there are subjects who do not determine the final results of their learning and there are also subjects who fail to determine the final results due to errors in the previous stage.

Abstract

This study aimed to examine the mathematical communication skills of female students in solving derivative problems in the eleventh grade at SMA Negeri 1 Sigi. The research followed a qualitative approach with a descriptive design. The study sample consisted of three female students selected based on a questionnaire focusing on feminine gender traits. Data were collected through written tests, interviews, and direct observation of the subjects. The dependability and credibility techniques were used to ensure the quality of the research findings. Data analysis involved three stages: data condensation, data presentation, and drawing conclusions. This study contributes to the existing literature by addressing the gap in understanding the mathematical communication skills of students with feminine gender traits, specifically in the context of solving derivative problems. The uniqueness of this study lies in the use of a feminine questionnaire for subject selection and the integration of mathematical language with everyday language and physical gestures in the evaluation of mathematical ideas. The findings revealed that female students with feminine gender traits demonstrated proficiency in all indicators of mathematical communication skills, including: (1) the ability to communicate their mathematical thoughts coherently and clearly to their peers and teachers; (2) effective use of mathematical language, such as numbers, letters, symbols, charts, graphs, and logical connections, in conjunction with everyday language and physical gestures when presenting, solving, and evaluating mathematical ideas during interactions with others; and (3) the capacity to explain mathematical ideas, situations, or relationships in written form. These results suggest that approaches combining mathematical language with physical interaction and everyday language can enhance the effectiveness of mathematical communication. The findings of this research can be utilized as a foundation for developing more inclusive and adaptive teaching strategies that consider gender differences in mathematics education.

Abstract

The purpose of this study was to describe the concept understanding ability of students in solving the problem of two-variable linear equation system. The method used is descriptive qualitative research. The subject of this research was 3 students taken from 26 students of class VIII SMPN 1 Balaesang. The results showed that the concept understanding of high mathematics ability students in restating concepts can restate concepts well using their own language, identify examples and non-examples and classify objects according to certain properties in accordance with the concept that can make mathematical modelling and determine equations and use the right solution steps according to the concept algorithmically. The concept understanding of medium ability students in restating concepts has been able to state concepts using their own sentences, identify examples and non-examples and are still lacking in classifying objects according to certain properties in accordance with the concept. The concept understanding of low ability students has not been able to achieve all indicators of concept understanding. Therefore, concept understanding is very important to be mastered by every student and the role of the teacher in facilitating the ability of each student.

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

The integration of ICT in learning is a component of 21st-century learning. Science and technology always develop rapidly from time to time. The purpose of this study is to determine the knowledge and abilities of junior high school mathematics teachers in STEM learning. This research was also conducted to determine student knowledge related to STEM learning. This study used a mixed method. The results showed that most junior high school mathematics teachers in the Donggala district did not understand STEM/STEAM learning. The teacher has also not been able to apply the STEM/STEAM approach in the learning process. Therefore, it is hoped that mathematics teachers in the Donggala district can apply a STEAM-based approach combined with local wisdom in the Donggala district. And it is necessary to conduct training to improve teacher competencies related to STEM learning.
