Abstract

Abstract. Learning outcomes are a measure of the success of students in learning the material delivered by the teacher. Data on students 'mathematics learning outcomes obtained at Bilah Hulu 2 High School showed that students' mathematics learning outcomes were relatively low so it was necessary to improve them, especially on mathematics subjects. The objectives of this research were to find out knowing the effect of mathmagic on the scramble learning model on student learning outcomes in the subject matter of Inverse Functions. This type of research is quantitative research using The One Group Pre-Post Test test Design. The research instruments used tests of student learning outcomes in the form of multiple choices. Data were analyzed by the T-Test, namely Paired Sample T-Test. The results average learning outcomes of class X MIA 1 Bilah Hulu 2 High School before being taught using mathmagic with a scramble learning model of 10.14 and a standard deviation of 3.563 and after being taught using mathmagic with scramble learning model of 16, 72 and standard deviation 2,987. Because the data obtained from the results of the t-test at a significance level of 0.05 is t count t table that is 16.784 2.045 then Ha is accepted. From these results, it can be concluded that there is a mathmagic influence with the scramble learning model on student learning outcomes by matching the question cards and answer cards available in random circumstances.Keywords: Mathmagic, Scramble, Learning Outcomes

Abstract

This study aims to describe the improvement of students' Mathematical Critical Thinking Ability (MCTA) through the Think Pair Share (TPS) Cooperative learning model. This type of research is a quasi-experimental with Nonequivalent Control Group Design. The population in this study were students of class X SMA Negeri 2 Padangsidimpuan. Through purposive sampling, research samples were taken from class X IIS 2 as the experimental group and class X IIS 1 as the control group. The research instrument includes an observation sheet on learning activities and student MCTA tests which include pretest and posttest questions. Data analysis using N-gain score, t-test. Analysis of the observational data showed the average value of learning management with a score of 4.48. Obtaining N-Gain with t-test on student MCTA data obtained a significance of <0.05. The average acquisition of the N-gain MCTA index of students in the experimental class was 0.42 and in the control class was 0.29. Through two-way ANOVA at the gender level with a learning model to improve students' MCTA, a significance of 0.736>0.05 was obtained. It was concluded that the application of TPS-type cooperative learning in improving students' MCTA was good. The TPS-type cooperative learning model's improvement was better than the regular MCTA of students.

Abstract

Village is a community unit that has territorial boundaries that has the authority to take care of all the interests of residents or the local community. The village is led by the Village Head who is assisted by village officials and supervised by the Village Consultative Body in accordance with Permendagri number 110/2016 regarding the duties and functions of the BPD. The lack of knowledge of residents about Information Technology such as the operation of Microsoft word and excel in terms of writing correspondence is an obstacle in their activities, especially for high school/vocational school level students or office workers. The aim of this Microsoft word and microwoft excel training is to improve the quality of Human Resources ( HR) for the people of Sidorejo Village, Labuhanbatu Regency. The methods in this training are the discussion method and the practical method. The results of this training show that there is an increase in the skills of the residents of Sidorejo Village, Labuhanbatu Regency in operating and using Microsoft Word and Microsoft Excel, this can help smooth their daily work and increase residents' knowledge about science and technology

Abstract

This study aims to describe the improvement of students' Mathematical Creative Thinking Ability (MCTA) in learning mathematics with the Contextual Teaching and Learning (CTL) approach. So that the goals that have been set can be achieved, quasi-experimental research is carried out with the design of the Nonequivalent Control Group Design. The population of this research is the students of class X SMA Negeri 2 Padangsidimpuan. The research sample was taken using a purposive sampling technique, namely class X MIA 3 for the experimental group and MIA 4 for the control group. The research carried out showed that the results of the MCTA students through the Independent Samples Test obtained a significance level of 0.00 <0.05. This means that there is a significant average difference between the increase in the MCTA of the experimental group students and the control group. Furthermore, the average value of the N-gain score for the experimental group is 0.41 and the control group is 0.29. This means that the improvement of students' MCTA through the CTL approach is better than learning with the conventional approach. Furthermore, with two-way ANOVA analysis, obtained a significance level of 0.196> 0.05. This means that there is no interaction with initial abilities with the learning approach in improving students' MCTA.
