Abstract

Functional thinking (FT) is individual’s cognitive process to identify the relation between variables and is essential for students to learn algebra. However, not much studies addressing the examination of the contents of FT problems within school mathematics textbooks, particularly in Indonesian curriculum. This study aims to describe the mathematics problems presented in junior high school mathematics textbooks of the new Indonesian curriculum (Kurikulum Merdeka) based on the FT framework. To reach this aim, the student mathematics textbook published by The Ministry of Education, Culture, Research, and Technology (Kemdikbud) in 2022 was used to conduct the analysis. The textbooks used were seventh and eighth-grade mathematics textbooks. The data was collected by observing the textbook's contents in the algebra domain. The analysis was based on the framework of FT consisting of recursive patterns, covariance, and correspondence. The results show that the FT tasks appear in the learning of algebraic terms, modelling with algebra, and linear functions. Moreover, this study also found that tasks in each topic develop students’ FT at different stages. Tasks in algebraic terms fulfill all FT’s stages in hierarchical order, tasks in modelling with algebra focus on the correspondence stage, and tasks in linear functions include all FT stages but not in chronological order; that is, recursive patterns, correspondence, and then covariation. In conclusion, this study finds that algebraic problems provided by Indonesian textbooks already support students’ FT. Thus, designing more FT tasks and connecting each task to different algebra topics might help students develop their FT.

Abstract

Some conditions are unconcerned with students believing they are learning mathematics. Students' disinterest increases when the situation is online learning due to the COVID-19 pandemic. In that case, fully online learning reduces students' mathematical and computing abilities. Therefore, this study aims to obtain a hypothetical learning trajectory in mathematics learning in constructing the skills to master mathematical and computational thinking for secondary school students. This study used part of the research development method of validation research which focuses on Hypothetical Learning Trajectory (HLT). The preparation of the HLT focuses on mastering the mathematical and computational thinking skills of junior high school students using teaching materials, learning media, and evaluation instruments on rank number and square roots materials. The subjects in this study were 30 junior high school students in class IX who took mathematics classes. The series of activities and forms of student learning assumptions become one complete trajectory for the purpose of learning achievement. A Hypothetical Learning Trajectory (HLT) was developed based on the findings of an analysis of the activities of the Junior High School Mathematics curriculum suite and PISA 2021, test results, initial observations during the learning process, and interviews with students and teachers. HLT preparation has an impact on creating learning designs that are ready to be continued at the implementation stage in the following class.

Abstract

The paper begins with a discussion of the characteristics of digitization that influence school mathematics, its goals and practices: the digitization of everything, the invisibility of computation, the era of big data and information on everything, and changes in the social role of mathematics due to increased global competitiveness. This leads directly to Theme 1, where we discuss the diminished economic and personal value of the ability to carry out routine mathematical procedures from arithmetic to calculus. Two other themes are then discussed: the reorientation of school mathematics content to support students to solve real world problems, and the need for students to understand about how mathematics can provide insight into real world problems, even when they are not able to actually do this themselves. These themes are only three of the many aspects of mathematical competence in the digital era which might have been chosen for discussion.

Abstract

This study aimed to explore students’ creative thinking process in fifth- grade elementary school in fraction problem solving based on gender differences. Subjects consisted of one male and one female with high mathematical ability. Data were collected by task-based interviews and analyzed through the sequence: data classification, data reduction, data presentation, interpretation, and conclusions. The creative thinking process in this research is a series of stages that students go through in creative thinking, including: exploring facts, identifying problems, generating ideas and completing ideas to produce solutions. By these stages, the subjects produced solutions in geometric and algebraic that showed their creative thinking that fulfilled fluency, flexibility and novelty. The subjects used algorithm solutions by repeating the completion steps. In this research, both subjects related their algebraic solutions with geometric solutions that has been produced. It was found that geometric solutions supported the subjects to deliver algebraic solutions and they related their understanding of fractions concepts to solve the problem. The more students’ knowledge or experiences associated with the problem, the more ideas for solutions they found. In this research, it was also found that there were some similarities and differences between the creative thinking processes of both subjects.

Abstract

This study aims to analyze the coordination and construction aspects of covariational reasoning of field dependent students’ prospective mathematics teachers in solving covariation problems. This research is qualitative research with the subject of research being field dependent prospective mathematics teachers of STKIP PGRI Jombang. The instruments in this study are the main instrument (the researcher himself) and supporting instruments in the form of GEFT, Covariation Test, and interview guidelines. Data analysis uses data reduction steps, data presentation, and conclusions. Based on the results of the study, the subjects coordinate the magnitude of variable changes and determine the pattern of change for linear covariation problems based on calculations from the results of the representation of covariation task-based problems to compile their change patterns, for linear students using students' own understanding without doing calculations. In the construction aspect, the subject constructs through the representation of the relationship of two variables into a graph by determining the coordinate axis with known variables and drawing a graph from the results of calculating the pattern of change in the relationship of two variables. From the depicted graph, the direction of the chart can be determined. The resulting graph corresponds to a given covariation task-based problem.

Abstract

Many studies showed that teachers' knowledge of instructional strategies is related to another component of pedagogical content knowledge. However, studies on teachers' reasons for choosing their instructional strategies still need to be reported. Three mathematics teachers were investigated using a case study research design. The data were gathered through two semi-structured interviews, pre- and post-observation, as well as observations. Pre-observation interviews explored teacher's knowledge of instructional strategies (KIS) based on their experiences or knowledge. Meanwhile, the post-interview investigated teachers' reasons for choosing instructional strategies based on the observations. Five to ten lesson hours were allocated to observe the teachers' activities in learning on the topic of linear equations and inequalities of one variable. A cross-case analysis was performed to compare the teachers' KIS and their reasons for choosing instructional strategies in teaching practice. The findings showed that lecturing, questioning, and solving problems are the most dominant strategies used by teachers. Only one teacher used group discussion in her teaching activities. The finding also indicates that the knowledge of the student's understanding, curriculum, beliefs, and teaching context are factors that influence teachers in choosing instructional strategies. In addition, the reasons for choosing those strategies are varied.
