The problem of partners in Community Service Activities is that teachers are not able to operate computers or laptops properly. As a result of these conditions, the teacher is unable to use Microsoft Word smoothly. On the other hand, the use of Microsoft Word is very necessary for teachers both for administrative purposes, the need for the preparation of scientific work or the preparation of teaching materials. The solution used to overcome partner problems is through Microsoft Word learning activities. The learning method implemented is through group discussions, deliberations, internal training and workshops. The results obtained were an increase in partner knowledge in operating Microsoft Word and the teacher gave a positive response to the training activities.

This study aimed to determine whether differentiation learning in junior high school mathematics learning was practical. The method used in this study is a quasi-experimental research design with Pretest-Posttest Control Group Design. The population in this study were all eighth graders of St Yoseph Private Junior High School Medan, which consisted of five classes with 32 people in each class. The sample in this study was 64 students consisting of 32 students for the experimental class and 32 for the control class. The results showed that the average student activity in content differentiation was 2.33 in the excellent category, the application of process differentiation was 2.33 in the excellent category, and the application of product differentiation was in a suitable category. The average value of teachers' ability to implement content differentiation is 3 in the excellent category, the average value in the implementation of process differentiation is 2.25 in the excellent category, and the implementation of product differentiation is 2.75 in the excellent category. Based on the results of research and hypothesis testing that has been carried out, the differentiation learning process runs effectively, which can improve students' mathematical abilities. This can be seen from the difference in the average post-test score of students in the experimental class and control class of 2.25%, the percentage of students who meet the KKM is 62.5%, the average student activity is 76.6%, and also the average level of teacher ability in managing differentiation learning in the experimental class is 89%. This research implies that differentiation learning is effectively used for junior high school mathematics learning

This study aims to describe students' difficulties in solving numerical patterns in the context of the Toba Batak ethnic culture after the implementation of the Realistics Mathematic Education Approach in the context of the Toba Batak Tribe Culture. Subjects in this study were students of class VIII Junior High School (SMP) totaling 32 people. The data collection tool used in this study is a test that totals ten questions in the form of a description. This type of research is a qualitative descriptive study. Data collection techniques are carried out by tests, observation, interviews, and documentation. Data analysis techniques were carried out by data reduction, data presentation, and concluding. The results showed that students had difficulty determining the sequence of numbers, determining the configuration of a sequence of numbers, determining the arithmetic series, determining the number of n first arithmetic series terms, determining the first term n row geometry, and determine the number of n first terms of the geometry series. The causal factor is that students are not able to distinguish the general formula concept of a sequence and the concept of configuration patterns from a sequence of numbers, operating error calculations and not understanding integer ranks.

Learning that involved the daily life accompanied by interesting learning media can be used as an option to help students in learning, particularly in improving students' concepts understanding. It is possible to do by utilization of familiar media that are generally liked by students. One of them is comic. Therefore a research about learning by comic based realistic mathematical approach was carried out in order to find out its effect on improving the skills of students concepts understanding on fraction material. This study is a quasi-experimental research. The population of study are 7th grade students of SMP RK Serdang Murni Lubuk Pakam on Academic Year 2019/2020. The first class that consist of 31 students are categorized as the control class and the second class consist of 32 students are experimental class. The pre-test and post-test questions were provided as an instrument of study. The data were analyzed using the Anova and Welch Brown-Forsythe tests to proof the hypotesis. Moreover, normality test with Liliefors test and the homogeneity test with the Levene’s test. The results of this study stated that learning with comics-based realistics mathematical approach has a significant effect on improving the skills of students concept understanding.

Sementara siswa pada kelas kontrol dibelajarkan tanpa menggunakan Lembar Aktivitas Siswa (LAS) dan menerapkan pembelajaran konvensional.Kata Kunci: Lembar Aktivitas Siswa, Model Pembelajaran KooperatifÂ Â Abstract. The objectives of the research are: (1) The validity of studentâ€™s Mathematic worksheet for tenth grade of senior high school using various cooperative leaning models; (2) The learning effectiveness of studentâ€™s Mathematic worksheet sheet using various cooperative learning. The method used is research and development that develops studentsâ€™ Mathematic worksheet as teaching media. The research findings are as follows: (1) Senior high school studentsâ€™ worksheet is valid with the average score 4.56 or 91.2%. It means the studentsâ€™ worksheet can be used in Mathematic learning; (2) Learning using studentsâ€™ Mathematic worksheet with various cooperative learning models is effective. It can be analysed based on the studentsâ€™ work observation, teacherâ€™s skills in managing the class, and the studentsâ€™ achievement in experiment class and control class. The students are treated by using studentsâ€™ worksheet and applying various cooperative learning models, those are Student Teams Achievement Division (STAD), Numbered Head Together (NHT), Think Pair Share (TPS), and Jigsaw in experiment class. In contradictory, the students in control class experienced learning without using studentsâ€™ worksheet and they got conventional learning.

This study aims to determine the impact of character education on the character of students at SDN 060914 Medan. The approach in this study uses a quantitative descriptive approach with survey methods. The sampling technique uses a purposive sample, namely by taking samples from fifth grade students with a total of 20 students. The research instruments used were interviews, questionnaires, and observation. The results of the research show that students' behavior in implementing character education which includes religious, honest, diligent, disciplined, and caring/responsible characters is in the pretty good category. As for the constraints on the lack of cooperation from parents to further foster students when they are at home, as well as their daily social environment. So the solution to these obstacles is to hold meetings with parents at the end of each semester.
