This study aims to analyze students’ difficulties in understanding the concept of Stokes’ Theorem in the Vector Calculus course. The method used is a descriptive qualitative approach with data collected through semi-structured interviews with mathematics education students who have studied the topic. The results show that students struggle to comprehend the relationship between line integrals and surface integrals, as well as to connect the concept of curl with vector direction in three-dimensional space. Limited understanding of prerequisite material and the lack of visual media further exacerbate these difficulties. Students reported that learning methods based on visualization and group discussion were helpful. This study recommends the use of contextual learning strategies and interactive media to improve students’ understanding of abstract concepts in Stokes’ Theorem.

This study was chosen because it is believed to be able to provide a positive impact on the mathematics learning process, especially in improving students' mathematical concept understanding abilities and reducing mathematical anxiety which is often an obstacle in learning. This is to analyze the effect of the Learning Start With A Question (LSQ) strategy with the Quizizz Application on students' mathematical concept understanding abilities and mathematical anxiety at SMP Negeri 2 Bilah Barat. This study used a quasi-experimental design with the Single Group Interrupted Time Series Design approach. The study population was all students of grade VII with a sample of class VII-1 totaling 32 students, selected using the Cluster Random Sampling technique. The results showed that the LSQ strategy with the Quizizz Application had a significant effect on improving students' mathematical concept understanding abilities and reducing students' mathematical anxiety. Based on the hypothesis test using the Paired Sample T-Test, a significance value of 0.001 was obtained, which was smaller than 0.05, so that the alternative hypothesis (Ha) was accepted and the null hypothesis (H0) was rejected. This study concludes that the application of LSQ with the Quizizz Application is effective in improving students' mathematical concept understanding and reducing students' mathematical anxiety at SMP Negeri 2 Bilah Barat.

This study aims to analyze the improvement of learning outcomes of grade VIII students at SMPN 34 Medan through the application of information technology-based learning media. This study uses the Classroom Action Research (PTK) method. The techniques utilized to gather data include lzearning implementation observation sheets (teacher activities), student activity observation sheets, student response surveys, and learning outcome exams in each cycle. The data gathered were evaluated by quantitative descriptive analysis and qualitative analytical methodologies. While qualitative analysis is used to comprehend the findings of student activity observations, quantitative descriptive analysis is utilized to assess student learning outcomes. As evidenced by the average learning achievement of grade VIII students at SMPN 34 Medan, which was 56.2% in the first cycle and significantly increased to 81.86% in the second, as well as the positive increase in student activity in the learning process despite a number of challenges noted in the student activity sheet during the first cycle the study's findings suggest that the use of information technology-based media in the classroom has the potential to increase the learning interest of grade VIII students at SMPN 34 Medan.

Community Service Activities are mandatory activities carried out by UIN North Sumatra students, especially at the Faculty of Tarbiyah and Teacher Training. PMM-4 students carry out community service activities in Bandar Magodang Village, Bintang Bayu District. One of the series of activities planned by PMM-4 students is a study house which is attended by the children of Bandar Magodang Village. This study house program aims to help the children of Bandar Magodang Village in brushing and maintaining good and correct dental health. This program is running well, this service activity is carried out through 3 stages, namely planning, implementation and evaluation. The method used in implementing this community service is a qualitative approach. Data were collected before and after the intervention to assess changes in children's knowledge and behavior. The results showed a significant increase in their understanding of the importance of brushing their teeth properly and maintaining dental health in general. The implication of these findings is the importance of ongoing dental health education in rural communities to improve children's dental well-being. This learning house action was completed on 18-19 August 2023 in one of the residents' yards in Bandar City, Bintang Bayu District.

The aim of this activity is to provide data to students about the intelligent use of digital media which can influence the turn of events and the use of science in the eyes of the public. This business is named "Socialization of the Smart Use of Digital Media for Students in Bandar Magodang Village" Bintang Bayu District, Serdang Bedagai Regency. The main strategy used by students in this effort is an effort technique that provides material to help students understand how to make better use of advanced media. Through this local area administration, universities can support the use of intelligent and locally significant data innovation.
