This study investigates the relationship between mathematics self-efficacy and problem-solving ability, exploring the role of the Jigsaw cooperative learning model in enhancing both factors. Self-efficacy, defined as students' belief in their ability to successfully perform mathematical tasks, has been shown to significantly impact students' problem-solving capabilities. The research focuses on understanding how this belief influences academic performance and how the Jigsaw model, which fosters collaborative learning, affects students’ self-efficacy and problem-solving skills. A survey-based research design was employed, with participants consisting of university students enrolled in mathematics courses. Data collection involved administering a self-efficacy scale to assess students' confidence in solving mathematical problems and a problem-solving test to evaluate their abilities. Path analysis was used to determine the relationship between self-efficacy and problem-solving skills, and the effect of the Jigsaw model was evaluated by comparing pre- and post-test scores between the experimental and control groups. The results revealed a strong positive relationship between self-efficacy and problem-solving ability (β = 0.45). Additionally, the Jigsaw model significantly enhanced this relationship, improving both students' self-efficacy and problem-solving performance. These findings highlight the importance of fostering self-efficacy in mathematics education and the effectiveness of the Jigsaw cooperative learning model in achieving this goal. The study provides valuable insights into improving teaching strategies in mathematics, particularly for subjects requiring critical thinking and problem-solving skills, by promoting a more interactive and supportive learning environment.

The influence of early mathematics learning and learning motivation on student learning outcomes is very significant [1]. Students' numeracy literacy skills need to be supported by the ability to learn mathematics as early as possible. Advanced mathematics learning needs to be supported by good arithmetic skills. Every learning process is expected to produce good learning outcomes. Conventional mathematics learning is difficult for low-level students to understand. Guidebooks that are in accordance with the learning curriculum tend to present mathematical concepts that are textual. In order for mathematics learning to be more interesting for students, it is necessary to develop learning media that are easily accessible to students and educators. One application that can be used is interactive Powerpoint [2]. In this community service, a learning media about arithmetic was developed that underlies every logic of calculation in advanced mathematics. Assistance was given to students in grade III of elementary school, with the pretest method, presentation of material using interactive Powerpoint media, and posttest. The validation test of the learning media was carried out by educators by providing an average test result of 84.36%. The results of this community service state that arithmetic learning media using interactive Powerpoint can be used in grade III of elementary school.

Children between the ages of four and six benefit greatly from the moral and motor skills development opportunities presented by kindergarten-level early childhood education programs. The purpose of this research was to determine whether the fine motor-based learning approach used by teachers at Nusa Indah Kindergarten in Bicak Village was successful in enhancing the students' fine motor skills. Using the number wheel and other interactive activities, youngsters may practice their fine motor skills while learning the fundamentals of mathematics. An novel learning medium was developed and evaluated using a Research & Development (R&D) approach. The study also utilized an observational method to analyze the medium's impact. The findings demonstrated that the approach considerably enhanced the fine motor skills, which encompass drawing and writing, of the children. The children's engagement and enthusiasm for learning were both boosted by the game-based activities. These results lend credence to the idea that preschool programs should take a more all-encompassing approach to teaching young children, one that prioritizes not just their cognitive but also their physical and emotional growth. This study adds to the body of knowledge on early childhood education curricula by highlighting the need of including fine motor development activities.

The rapid development of the times and technology today has given rise to many innovations and conveniences, including in the field of education for students and teaching staff. Learning methods are no longer conventional or face-to-face in the classroom, but through online-based devices the teaching and learning process can still run, especially when the Covid 19 pandemic hit. Mamuju Regency, West Sulawesi Province, in the education sector, especially at primary school level or equivalent, there are 310 schools including state schools and private schools. In general, interest in informal education, one of which is tutoring, is still low. This journal presents data and results of mathematics learning assessments at the Ranu Prima College Tutoring Institute, Mamuju branch. The aim of presenting this data is to determine the effectiveness of tutoring in the post-pandemic period and its existence in the future. The results obtained from this activity show that the offline/face-to-face tutoring system is still more effective than the online learning system. This is proven by assessments by parents/guardians of students and students' enthusiasm for the existence of tutoring even though the duration of implementation is relatively short. Of the total of 30 participants, 25 participants remained until the program was completed, providing feedback in the assessment and assessing that the tutoring was effective in equipping students to prepare the final school exams.

One of the causes of low student learning outcomes is the use of learning models that are monotonous and tend to be boring, so innovation in learning is needed. The integration of technology into the education and learning process reflects an innovative effort. One model that can make it easier for students to understand and can support technological developments is the blended learning model. Quipper School is an online learning platform that can be used in the blended learning model. This research aims to determine whether or not there is an influence of the blended learning model using Quipper School on the mathematics learning outcomes of class XI MA Nurul Jadid students. This research is quantitative research with a quasi experimental type.
