Boredom is a mental state characterized by discomfort and dissatisfaction caused by insufficient introduction of stimulus, challenge, or meaning in the environment. Objective: This study aims to describe students' boredom profile in solving mathematics problems based on their computational thinking ability. Methods: The method used was a descriptive qualitative approach with the subject of 62 students consisting of 63% female students and 37% male students of class IX SMP Negeri 1 Semarang, then took nine students with purposive sampling technique, taking subjects based on advanced, intermediate, and basic computational thinking ability tests, taken three each category based on recommendations from subject teachers. Findings: Student boredom is influenced by five factors, namely disengagement, high arousal, inattention, low arousal, and time perception. Students with advanced computational thinking ability generally do not feel bored because they feel challenged, although they can lose interest if the problem is too easy. Students with intermediate computational thinking ability have relatively low boredom, remaining engaged despite difficulties. In contrast, students with basic computational thinking ability are more susceptible to boredom due to difficulty understanding problems, frustration, a desire to quit, and a perceived lack of engaging activities. To overcome the problem of boredom, the recommendation from this study is to provide content-differentiated learning for each student, this can also be a recommendation for further research. Conclusion: Students with advanced computational thinking can feel bored if the problems given are too easy. Meanwhile, students with basic computational thinking feel bored when they find it difficult to understand the problem. Keywords: boredom, mathematics, problem-solving, computational thinking.

Self-regulated learning is a crucial aspect of the learning process for students. This ability is often overlooked due to the challenges of inaccurate measurement. This study aims to evaluate the quality of a self-regulated learning scale developed through an analysis of respondent responses. The research employed a descriptive quantitative approach using the Rasch Model as the analytical method. The instrument used consisted of 30 statement items. The study sample included 59 mathematics education students selected through cluster random sampling from two universities in different districts. The analysis results indicated that, after three calibration processes, the self-regulated learning scale was refined to 28 items with excellent quality. Furthermore, the responses of 58 students demonstrated a high level of consistency. Thus, self-regulated learning scale has good validity and reliability, making it a dependable tool for measuring self-regulated learning abilities. The implications of this study include the provision of a practical and reliable instrument for researchers and educators to support further studies and serve as an evaluation tool in learning development.

Although self-efficacy is widely acknowledged as a key to academic success in mathematics, limited research has examined how social persuasion strategies can be systematically integrated into multimedia learning to enhance self-efficacy and manage cognitive load. This study addresses the gap by examining the effects of integrated social persuasion prompts within mathematics instruction, focusing on cognitive load, self-efficacy, and problem-solving achievement. The first experiment compared worked example-based instruction with and without social persuasion, involving 66 undergraduate students enrolled in a multivariable calculus course for the first time. Instructional materials on parametric equations were delivered in a printed booklet and designed in alignment with Cognitive Load Theory. Social persuasion prompts were written on top of each worked example and problem-solving. The findings revealed that there was no significant different impact of written social persuasion, however the social persuasion significantly reduce cognitive load but increase self-efficacy. The second experiment recruited another 56 undergraduate students enrolled in the same multivariable calculus course studied the same worked examples in the format of multimedia. The results demonstrated that there was a strong impact of audio social persuasion on worked examples with regards to achievement, cognitive load, and self-efficacy level. This study provides profound evidence for integrating social persuasion in worked examples as it could enhance achievement, lower cognitive load, and improve self-efficacy. Further research on audio-based persuasion in multimedia format is discussed.
