Abstract

The ability to think creatively is an important skill in the world of education, especially for students of the Primary School Teacher Education Study Program (PGSD). In learning mathematics, especially geometry, this ability is crucial for understanding concepts in depth and solving problems innovatively. However, there are still many students who show limitations in generating creative ideas, especially in the aspects of originality and elaboration. Therefore, this research aims to analyze the creative thinking abilities of PGSD students in open problem-based geometry learning, which gives students the freedom to explore various solutions in solving geometric problems. This research uses descriptive qualitative methods with data obtained through interviews, observation and document analysis. Research informants include lecturers, PGSD students, heads of study programs, librarians, and the curriculum development team at STKIP PGRI Trenggalek. The research results show that the open problem-based learning method is effective in improving students' fluency and flexibility abilities. However, in the aspects of originality and elaboration, several obstacles were still found that required more intensive guidance and the use of supporting technology. With the right approach, this method can be a solution to optimize students' creative thinking abilities in learning geometry.

Abstract

Collective argumentation is a process in learning that can be used to train communication skills, collaboration, and understanding of mathematical concepts. In this process, both teachers and students play an active role, which is called participation. This study aims to describe the structure of collective argumentation and student participation in solving geometry problems in the classroom. This research method is a qualitative case study. The subjects in this study were a mathematics teacher with 11 years of teaching experience at the junior high school level and six 9th-grade students who had an interest in mathematics from two different classes. The structure of collective argumentation shows that this learning focuses on students while the teacher acts as a facilitator. It can be seen from the more significant number of actions taken by students than teachers. In terms of participation, teachers more often act as ghostee, while students participate more as spokesman. Overall, this study reveals the structure of argumentation in solving geometry problems at each stage of Polya. Questions and explanations given by the teacher influence students' collective argumentation. A teacher must have questioning and communication skills so that students can actively participate in learning in the classroom.

Abstract

Self-regulated learning is one of the important factors in learning to control oneself in thinking and acting. The purpose of this research is to analyze how much students have achieved their independence in learning. Student learning independence includes all matters of student learning independently without the help of others, student learning motivation or things that affect student independence in learning, especially in learning mathematics. This analysis study will be continued as an effort to improve self-regulated learning. The scope of self-regulated learning was analyzed by descriptive quantitative method through data collection techniques in the form of questionnaires on the object of research taken from a population of 25 students. Data collection was carried out with a questionnaire consisting of 20 statements from indicators of students' self-regulated learning ability. In learning mathematics, students who have initiative and instrinsic learning motivation, apply learning targets, and set a learning schedule in the percentage of almost half of the students do according to these indicators of independence. Almost all students diagnose learning needs, view difficulties as challenges, utilize and seek relevant sources. However, a small proportion of students lack self-efficacy or confidence in their abilities and are still low in evaluating the learning process and results. So that as an educator this needs to be considered to be able to improve students' self-regulated learning abilities (learning independence) in order to improve student achievement.

Abstract

This study aims to uncover and analyze hidden misconceptions in algebraic understanding among first-year students in the Mathematics Education Department at a private university in Malang. Conducted from January to March 2024, the research involves two first-year students as subjects. The first subject exhibits the misconception known as "illegal canceling," while the second subject demonstrates the "assumption of distributivity of exponents." Utilizing a qualitative research methodology, diagnostic interviews and problem-solving tasks were employed to identify and understand these misconceptions. Our findings indicate that these hidden misconceptions significantly hinder the students' ability to correctly solve algebraic problems and understand underlying concepts. For the first subject, the error in illegal canceling often led to incorrect simplifications, while the second subject's erroneous application of exponent rules resulted in fundamentally flawed solutions. By systematically categorizing these misconceptions, the study offers tailored instructional strategies to effectively address and correct them.This research highlights the critical need for early detection and targeted intervention in mathematical education. By providing a deeper insight into specific algebraic misunderstandings, the study suggests practical approaches for educators to enhance their teaching methodologies, ultimately improving students' overall algebra comprehension. The novelty of this research lies in its detailed focus on hidden misconceptions and the provision of actionable solutions, offering a fresh perspective on improving algebra education for first-year university students.
