Abstract

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.

Abstract

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

Abstract

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.

Abstract

This study was conducted with the aim of determining the influence of the Everyone is a Teacher Here learning model with the help of ice breaking on students' mathematical numeracy literacy and to find out the average numeracy literacy ability taught with the Everyone is a Teacher Here (ETH) learning model with the help of ice breaking whether it is higher than using conventional learning on comparison material in grade VII SMP Negeri 31 Medan. This type of research is quantitative with quasi experimental design. These results show that H1 has an influence on the Everyone is a Teacher Here (ETH) learning model with the help of ice breaking on students' mathematical numeracy literacy, judging from the t test showing sign results. (2 tailed) of 0.01 < 0.05. The H2 test has no effect of ice breaking on students' mathematical numeracy literacy, judging from the t test shows the results of sign.(2 tailed) of 0.07 > 0.05. As for H3, there is an influence of the Everyone is a Teacher Here (ETH) learning model with the help of ice breaking on students' mathematical numeracy literacy, judging from the f test obtained sign. (tailed) by 0.00 < 0.05. In the N-Gain Score test, Ha is accepted, namely the increase in numeracy literacy taught with the Everyone is a Teacher Here (ETH) learning model with the help of ice breaking higher than students who obtain conventional learning, with an average N-Gain Score in the experimental class of 0.71 > an average N-Gain Score in the control class of 0.41.

Abstract

Differentiated instruction is proposed to ensure that students receive learning activities that meet their prior-ability, characters, or needs. This study aims to examine the mathematical problem-solving ability of students who received differentiation learning in comparison to those who attended conventional learning. Conducted in a Catholic Junior High School in Medan during the 2020/2021 academic year, this quasi-experimental study was set in Pretest-Posttest Control Group Design. The population in this study were all eigth-graders from 7 parallel groups with 31 people in each. The sample in this study was 22 students consisting of 11 students for the experimental class and 11 students for the control class. The results showed that the average value of students' mathematical problem-solving abilities who participated in differentiation learning was 71.02, while that of conventional learning was 62.73. The difference in the average value of students' mathematical problem-solving abilities in the experimental class and control class is 8.29. From the results of hypothesis testing, the value of tcount = 2.68 and ttable = 1.725 means that tcount t table is 2.68 1.725. This means that Ha is accepted and Ho is rejected, hence, the mathematical problem solving ability of students who joined differentiation learning (Differentiated Instruction) is better than those who attended the conventional learning.
