Abstract

Mathematics research often focuses only on students' learning outcomes without considering their emotional aspects. This study aims to describe the tendency of students' sentiment toward mathematics in general and partially based on mathematics learning outcome groups, namely high, medium, and low. In addition, a mood analysis was conducted using Ekman's Basic Emotion classification. Data collection techniques are questionnaires and documentation. The questionnaire contains open questions about students' opinions on mathematics and closed to queries for student demographics. Documentation is done by collecting test scores from student grade books. This study used a descriptive method with data in the form of 72 comments from grade XI high school students in Bandung City, which were analyzed using the Orange Application Sentiment Analysis. The results of the study showed that (1) student sentiment was generally dominated by positive sentiment at 72.22%, (2) positive sentiment also dominated the groups of students with high, medium, and low learning outcomes, with a percentage of more than 68%, and (3) the results of the classification of emotions based on Ekman's Basic Emotion indicated that "joy" was the most dominant emotion, while "anger" had the lowest frequency of occurrence. This study provides new insights regarding students' emotional aspects in mathematics learning, which can be used to improve teaching strategies.

Abstract

The purpose of this study was to analyze students' proportional reasoning ability. The research subjects consisted of 21 students of VIII class in one of the public junior high schools in Semarang City who had obtained comparison materials (ratio and proportion). Data collection used test instruments that were developed based on indicators of proportional reasoning ability consisting of 6 questions. The data were analyzed qualitatively with data reduction analysis procedures, data presentation, and conclusion drawing/verification. The results showed that (1) none of the students met all the indicators of proportional reasoning ability, namely the ability to understand proportional relationships, solve proportional problems of missing values, numerical comparisons, qualitative predictions, distinguish proportional and non-proportional problems, and solve proportional relationships of inverse values, (2) all students have been able to understand proportional relationships, but they are still very limited in their ability to distinguish proportional and non-proportional problems, and solve proportional relationships of inverse value, and (3) the strategy most often used by students to solve proportional reasoning problems is the cross-multiplication strategy.

Abstract

Research on teachers' ability to prepare lesson plans has not shown good results, whereas there have been many studies on efforts to improve teachers in preparing lesson plans. Still, no research explicitly describes the ability of teachers to develop indicators. This research aims to describe the understanding of mathematics teachers in creating learning indicators. This research is quantitative research with a survey method. The sur- vey was conducted on 51 Mathematics Teachers in Cirebon City. The research instrument used was in the form of a questionnaire regarding the indicators of developing learning indicators. The results showed that (1) most teachers still did not understand the steps of developing learning indicators (2) teachers still had difficulty determining operational verbs (KKO) of knowledge, conducting processes, implementation, and evaluation, (3) there were still teachers who thought the affective and psychomotor aspects could not be assessed in mathematics, (4) most teachers have developed at least three indicators in a basic competency, while almost half of the sample assumes the characteristics of students and schools do not affect developing learning indicators.

Abstract

Pythagorean's theorem is a fundamental concept in mathematics that is widely used in various fields, including geometry, physics, and engineering. The ability to understand and apply these theorems is important in solving geometric problems and calculating distances or angles in real contexts. However, there are learning obstacles and difficulties for students in solving the problems of the Pythagorean theorem. This study aims to describe the learning obstacles and difficulties of students in solving Pythagorean theorem material through Systemic Literature Review (SLR). The article search strategy applies inclusion and exclusion criteria. The selection process was 19 selected articles using CASP checklist with articles coming from Google Scholar, Scopus, Springer Link, IEEE Explore, and PubMed databases. Based on the results of the study, it was obtained that students' learning obstacles came from epistemological obstacles, ontogenic obstacles, and didactical obstacles. The students' difficulties are dominated by conceptual difficulties. Learning obstacles cause learning difficulties.  Studying students' learning obstacles and difficulties can assist a teacher identify student learning problems.        Keywords: learning difficulties, learning obstacles, pythagorean theorem, systematic literature review.DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1939-1960

Abstract

Computational Thinking (CT) skills are essential in mathematics education, particularly in data processing topics. This study aims to analyze the CT skills of 7th-grade junior high school students based on four main components: decomposing, abstraction, pattern recognition, and algorithmic thinking. A qualitative phenomenological approach was employed, involving 14 students selected purposively based on their diverse academic performance levels. Data was collected through classroom observation, CT skill tests focusing on data processing tasks, and in-depth semi-structured interviews to explore students’ problem-solving strategies and cognitive processes. The findings reveal varied CT competencies among students. For decomposing, 29% of students demonstrated high ability, effectively breaking down complex problems into manageable steps, while 36% exhibited moderate skills. In abstraction, the majority (57%) struggled to filter relevant data from irrelevant ones, highlighting this as a key area for improvement. Pattern recognition showed 36% of students in the high category, recognizing and logically explaining data trends, whereas 29% remained in the low category. Algorithmic thinking presented the strongest performance, with 43% of students categorized as high, showcasing structured and logical approaches to solving data-related problems. The study highlights the need for targeted interventions to strengthen abstraction and pattern recognition skills, crucial for comprehensive data analysis. By identifying strengths and weaknesses in CT skills, this research provides insights into designing more effective teaching strategies and developing CT-oriented curricula. The findings contribute to mathematics education by addressing 21st-century skills, equipping students with critical thinking and analytical capabilities needed in a data-driven world.         Keywords: computational thinking, mathematics, data processing, junior high school. DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1809-1823
