Abstract

Mathematical proof problems are often considered difficult by students, making them a major challenge in mathematics education. While many studies have been conducted to explore the causes of these difficulties, none have deeply investigated the reasons behind the failure in proof construction. This study aims to explore the causes of students' failure in producing valid mathematical proof constructions through their cognitive structures. The research uses an assimilation and accommodation framework. A qualitative descriptive research method was employed, with data collected through think-aloud protocols performed by 17 students. Each student completed a proof problem alternately at different times, followed by interviews to further explore their thinking structures. Based on the data analysis, three types of cognitive structures were identified that explain the failure in mathematical proof construction: (1) incomplete cognitive structure with schema disconnection, (2) schema mismatch, and (3) immature schema. Based on these findings, it is recommended that lecturers incorporate specific learning  strategies, such as concept mapping activities to reinforce conceptual connections and structured proof validation exercises to address schema incompleteness and immaturity, thereby improving students' cognitive structures.

Abstract

Computational Thinking Skills (CTS) possessed by Indonesian students are not yet in the good category. This skills have not been integrated in learning. This is in accordance with the results of preliminary research at SMP Negeri 8 Semarang that CTS are a new concept for science teachers, including learning media used by teachers have not helped train students' CTS. Through preliminary research, it is known that science teachers give a positive response to the use of technology-based learning media that train students' CTS, one of which is a science educational game using Scratch. The purpose of this study was to analyze the validity and determine the profile of students' CTS after using science educational games. The type of research used is development research with the ADDIE model. The instruments used are expert validation questionnaires, student readability sheets, and tests after using science education games. The results showed that the science education game was valid with a score of 0.89. The readability of science education games is very good with a score of 96.7. Through the test, it was found that the percentage of students with high computational thinking ability was 56.66%, medium 26.66%, and low 16.66%. Based on the research that has been done, it can be concluded that the science education game is valid and can train CTS of junior high school students.

Abstract

There are many difficulties that can be identified when students solve mathematic problems especially in solving probability word problems. This study was conducted to identify the major obstacles faced by matriculation college students while solving the probability of an event word problems. Seven college students were the sample for this case study. Clinical interviews are used as a data collection. This data collection technique was selected based on the researcher’s observation on the participants as they answered the probability word problem task. The task was given during the interview session. Semi structured interviews are used to obtain in depth information. Think-aloud analysis involves observations leading to individual behaviours in the oral or nonverbal form of participants and the researcher’s field notes. Participants were found to have difficulty interpreting probabilities. There are three categories of difficulties that have been identified, namely not knowing the meaning of the word, not knowing the nature of the probability and not being able to identify the goal of the probability word problem.
