This research aims to determine the thinking activity types dominated by a mental process in producing answers characterized by automatic, unconscious, and subjective-empirical processes (system 1) in solving problems so that the default-interventionist interaction occurs. This research novelty is the formulation of the contents and thinking activity arrangement adapted to students' thinking when solving problems. The problem used in this research is a mathematical problem that triggers students to produce answers quickly with confidence that the answers are correct at a high level. Another problem is about probability because the mode of occurrence of students' learning difficulties at the secondary school level occurs when learning the concept of probability. This is qualitative research with a case study approach. The research subjects were students of Mathematics Education in semester 1. The results showed that thinking activity one could condition the occurrence of type 1 default-interventionist interaction. Thinking activity two could condition the occurrence of type 2 default-interventionist interaction. Thinking activity three could condition the occurrence of type 3 default-interventionist interaction. This research concluded that the default-interventionist interaction occurred because the content and arrangement of the thinking activity conditioned the subjects to pay attention to information gradually and change the subjects’ beliefs. Lecturers were recommended to produce, develop, and research thinking activities on topics other than probability at various levels of education. The default-interventionist interaction was essential to be conditioned when system one dominated students' thinking, causing difficulties.

This study explores the impact of integrating a Statistics Board teaching aid within a Problem-Based Learning (PBL) model to foster students’ critical thinking skills in learning statistics, specifically in the topic of single data. Employing a qualitative case study approach, the research involved prospective mathematics teachers and undergraduate students enrolled in an Offering E class of a Mathematics Education Program. Data were obtained through classroom video recordings, observational notes from the lecturer, and the use of the Statistics Board during learning sessions. The collected data were analyzed using an interactive analysis technique, encompassing data condensation, data display, and conclusion drawing. Findings demonstrate that the incorporation of the Statistics Board within a PBL setting significantly enhances students' engagement and conceptual understanding while promoting the development of higher-order thinking, particularly critical thinking. The tangible and visual nature of the teaching aid enabled students to navigate abstract statistical concepts more intuitively and collaboratively solve contextual problems. This research affirms the pedagogical value of integrating concrete teaching aids and student-centered learning models in mathematics instruction. It recommends the use of the Statistics Board as an effective instructional resource for both practicing teachers and teacher candidates, offering a pathway toward more innovative, engaging, and cognitively enriching mathematics classrooms.

This study employed a qualitative case study approach to investigate the effectiveness of the Musi board in enhancing students’ understanding of the abstract mathematical concepts of Greatest Common Divisor (GCD) and Least Common Multiple (LCM). These topics were often difficult for students due to their abstract nature and the limited use of concrete learning media. The participants were third-semester students from Offering E in the Mathematics Department at Universitas Negeri Malang. The learning process was conducted using the Problem-Based Learning (PBL) model, where the Musi board functioned as both a visual aid and a tool for collaborative problem solving. The teaching sequence followed five PBL stages: problem orientation, student organization, guided investigation, group presentation, and evaluation. Data collection included classroom observations, video recordings, student worksheets (LKPD), and written feedback from the course lecturer. The data were analyzed using Miles and Huberman’s interactive model consisting of data reduction, data display, and conclusion drawing. The findings revealed that the Musi board helped students concretize abstract mathematical ideas, making it easier to grasp and apply GCD and LCM concepts in problem-solving contexts. It also encouraged active participation and collaborative learning. The implication of this research was that integrating simple, culturally relevant, and interactive media like the Musi board into mathematics instruction could significantly improve conceptual understanding. Teachers were encouraged to incorporate such tools into their practice to make abstract content more accessible and engaging for students.

The exponential power rule was one of the materials studied at the high school level. Students tended to memorize it rather than understand it. This caused students to have difficulty in applying the concept of exponents when working on non-routine questions. The ability to prove the properties of exponents in a simple way was needed to improve students’ understanding, so a manipulative medium for the exponent power property called PLAKAT was created. This research aimed to examine the application of learning using the manipulative medium for the exponent power property known as PLAKAT. The research method used was qualitative with a case study approach. The instruments used to collect data included the manipulative media, video recording equipment, and observation notes. The subjects involved were practical students and audience students. The data collected consisted of video recordings and notes. The data were analyzed using interactive methods. The results of the research showed that this medium was useful for increasing students' understanding of the exponent power property. However, PLAKAT had a weakness: it did not have a rope, so it could not be hung, making its use less practical. This shortcoming served as a suggestion for teachers and students who intended to use this medium to prepare a more complete version to support smoother learning.
