Abstract

Probability theory is inherently abstract and structurally complex, often creating substantial cognitive barriers for students when solving problems. This study aims to formulate a genetic decomposition of core probability concepts based on the mental structures constructed by undergraduate learners. Guided by the APOS (Action–Process–Object–Schema) theoretical framework, the research employed a three-phase methodological cycle: (1) epistemological analysis of fundamental probability concepts, (2) design and administration of diagnostic and instructional instruments, and (3) analysis and validation of students’ cognitive structures. The study was conducted at two universities in Central Java, Indonesia, involving four mathematics education undergraduates enrolled in an introductory probability course. Data were collected through content analysis, domain-specific assessment instruments, and semi-structured interviews. The APOS framework was used to trace students’ mental constructions in relation to classical probability, independence, conditional probability, total probability, and Bayes’ theorem. The results reveal that students had not fully internalized the mental objects and schemas required to coordinate these concepts during problem-solving activities. Their reasoning remained largely at the process level, particularly in representing sample spaces, applying counting techniques, and thematizing probability structures. Nonetheless, several elements of their cognitive behavior aligned with the refined genetic decomposition. The findings highlight the necessity of strengthening students’ APOS-based mental constructions to support the development of coherent probabilistic schemas and enhance conceptual as well as procedural fluency.

Abstract

Abstract:  The main problems faced by partners include teachers' low ability to develop assessment instruments that are suitable for deep learning and 21st century-oriented learning, and teachers' suboptimal integration of local cultural values into assessment. This activity aims to improve teachers' ability to develop ethno-edutainment-based creative problem-solving (CPS) assessment instruments for deep learning and equip teachers with the skills to integrate local culture into assessment through the ethno-edutainment approach. The activity was carried out through the stages of planning, socialization, mentoring, simulation, and evaluation with a participatory and active learning approach. Teachers were provided with deep learning materials, CPS instruments, and ethno-edutainment applications, then directly assisted in developing and presenting locally-based assessment instruments. The results of the activity showed a significant increase in teacher competence, where the average ability of teachers in developing CPS assessment instruments for deep learning increased from 54% at the initial stage to 83.2% after the activity, while the ability to integrate local cultural values into assessment increased from 52.2% to 85.2%. These results indicate that assistance in developing ethno-edutainment-based CPS instruments is effective in improving the professional competence of elementary school teachers.Abstrak: Permasalahan utama mitra meliputi rendahnya kemampuan guru dalam menyusun instrumen penilaian yang sesuai dengan pembelajaran mendalam dan berorientasi abad 21 dan belum optimalnya guru dalam mengintegrasikan nilai budaya lokal dalam penilaian.

Abstract

Parenting is a treatment or way of educating parents in order to meet the needs and educate children in everyday life. In a family, the presence of parents is very important for the development of a child's personality, because the family is the first and foremost environment that will influence several aspects of child development, including the child's polite attitude. But not all children have complete parents, there are some children who are so unlucky that they only have one parent. But how to educate single parents is not much different from parents who are intact in instilling child courtesy. The cultivation of polite attitudes given by single parents to children is to provide understanding of what is good and bad and to give good examples to their children, so that children are more accustomed to seeing good things and can be imitated by children in everyday life. In this article, we will describe the polite behavior of children seen from the parenting styles applied by single parents

Abstract

This research aimed to investigate the learning interest of fifth grade students at SD N Winong 01 Pati. This research utilized a qualitative descriptive method. This research was conducted at SD N Winong 01 Pati, Desa Winong, Kecamatan Winong, Kabupaten Pati. The focus of this research was students’ learning interest towards WhatsApp-based online learning. The primary sources of data in this research were five 5th grade students at SD N Winong 01 Pati. In addition, the secondary sources of data were obtained through documentation of the students’ assignments and WhatsApp Group, articles, reference books, and other supporting data. The result of this research showed that students were often bored during learning at home. Moreover, teachers gave assignments without giving materials or media to support the process of learning everyday. This caused the students to be less interested and not involved in learning. Students only responded and focused on the assignment given to them. The demand to submit the assignment everyday made the students motivated to learn and they did the assignment diligently. Besides, students also became more diligent and disciplined in learning and had a schedule of learning.

Abstract

Students’ mathematical problem-solving skills and their level of self-confidence are still relatively low, one of the contributing factors being that mathematics learning is still dominated by a teacher-centered approach. One solution to overcome this problem is to implement the Missouri Mathematics Project (MMP) learning model. This study aims to compare the average mathematical problem- solving ability of students taught using the MMP model assisted by Articumath Ratio media with those taught through the direct instruction model, as well as to examine the influence of self-confidence on mathematical problem-solving ability. The research employed a quantitative method with a quasi-experimental design. The study population consisted of seventh-grade students of SMP 2 Gebog, with the sample selected using probability sampling through simple random sampling, resulting in two groups: class VII I and class VII F, totaling 62 students. The independent variables in this study were the MMP learning model and Articumath Ratio media, while the dependent variables were students’ mathematical problem-solving abilities and self-confidence. The initial data analysis included tests of normality, homogeneity, and mean similarity, while the final data analysis used tests of normality, homogeneity, and hypothesis testing. The findings revealed that the average mathematical problem-solving ability of students taught with the MMP model assisted by Articumath Ratio was higher compared to those taught with direct instruction. Moreover, self-confidence positively influenced mathematical problem-solving ability by 82.8% among students taught with the MMP model supported by Articumath Ratio.

Abstract

Mathematical problem-solving skills are important to help learners apply mathematical concepts in everyday life. The mathematical problem-solving abilities of students at SMP Negeri 1 Bae Kudus are still considered low, as evidenced by the preliminary study results on the VII-B class students with an average score of 37.34. Based on these findings, this study aims to improve the mathematical problem-solving abilities of seventh-grade students thru the application of the Realistic Mathematics Education (RME) learning model assisted by Ethmas QR-Code media. This research uses a quantitative approach with a quasi-experimental design, where class VII-B is designated as the experimental group and class VII-A as the control group. The selection of the sample was conducted using the simple random sampling technique. The study population consisted of 256 students, with a sample of 2 classes comprising 64 students. Initial data analysis includes normality tests, homogeneity tests, and mean equality tests, while final data analysis involves independent two-sample t-tests, N-Gain calculations, and independent two-sample t-tests. The instrument used in this study is a test to measure students' mathematical problem-solving abilities. The results of this study indicate that: (1) The average mathematical problem-solving ability of students taught using the RME learning model with Ethmas QR-Code learning media is better compared to the average using the direct learning model. (2) There is a significant improvement in mathematical problem-solving abilities before and after the implementation of the RME model aided by Ethmas QR-Code media, with a high category of improvement. Further research is needed to study the ethnomathematics of Kudus culture and mathematical problem-solving abilities in flat shapes in order to generate innovative findings in mathematics education.
