Abstract

The aims this research was to analysis students error using Newman Procedure. The subject this research is student of class in X MM1 SMKN 1 Balongan. Many sample were used by 6 student, consist of 2 students with lowest rank, 2 students with intermediate rank, and 2 students with high rank. The result of the analysis show that the average reading error is 38,86%, the average error in comprehension is 39,43%, the average transformation error is 34,86%, the average processing error is 52,57%, and the encoding error rate is 84,57%. Based on the result of the analysis of the six students, it can be concluded that students rarely write things that are know and asked and rarely write conclusion. This is what causes encoding to always win from the four previous stages.

Abstract

The purpose of this study are 1) To find out the mathematics learning outcomes of students with the Jigsaw type cooperative learning model and the Team Games Tournament (TGT) type of cooperative learning model whether it will be better than conventional learning models. 2) To find out the average learning outcomes with the type of jigsaw cooperative learning model and Team Games Tournament (TGT) students can reach the KKM. Jigsaw and TGT type of cooperative learning model is one type of cooperative learning that places students in learning groups of 5-8 people who have different abilities, genders and ethnicities or races. The method used in this research is the experimental method. The population in this study were all VII grade students of SMP Negeri 1 Purwojati in the 2018-2019 school year, totaling 221 students. Of the seven classes, three classes were randomly selected as research samples, namely class VII E which was treated as a jigsaw class, class VII F as a conventional class and VII G as a TGT class. The results of data analysis show that: 1) Mathematics learning outcomes of Grade VII students of SMP Negeri 1 Purwojati taught using the Jigsaw learning model are relatively high with an average value of 81.281 of 32 students. 2) Mathematics learning outcomes of Grade VII students of SMP Negeri 1 Purwojati taught using the TGT learning model are relatively high with an average value of 78.781 out of 32 students.

Abstract

This study aims to determine the effectiveness of the TGT learning model containing ethnomatics on students' mathematical problem solving abilities wake up flat side space (cubes & beams). Effectiveness can be seen from the level of completeness of students 'mathematical problem solving abilities, the comparison of students' mathematical problem solving abilities of the experimental class with the control class and the influence of students 'learning activities on students' mathematical problem solving abilities. The type of research in this study is quantitative research, with experimental research methods, and the approach used is the Posttest Control Group Design approach. The population in this study were eighth grade students of MTs Muhammadiyah Bumiayu. The sample used in this study is class VIII A as an experimental class and class VIII B as a control class. The method of sampling is the Cluster Sampling technique. Analysis of the data used are normality test, homogeneity test, completeness test, proposition completeness test, average difference test and simple regression test. The results of this study are the TGT learning model is loaded with effective ethnatics on students' mathematical problem solving abilities.

Abstract

This research is bades on the low ability of student’s matematical problem solving. The result of midterm examination on the second semester in mathematical subject for eighth grade student in the academic year 2018/2019 showed that the average score of the students was 56,46, and it means that many of the students have not been able to pass the standard KKM of 70. The objective of this study was to find out effectiveness of Problem Based Learning assisted with BUTIK on the ability of solving mathematical problems especially in Single Data statistics subject. The effectiveness seen from the compare of Problem Based Learning assisted by BUTIK with conventional models on achieving minimum completeness criteria (KKM) and the better comparison or not between BUTIK assisted Problem Based Learning with conventional learning models. The researcher used Posttest-Only Control Design in this research. The samples of this study were chosen by the used of Cluster Random Sampling. The data were analyzed by using normality, homogeneity, average, completeness, and comparison. The result of this study showed that Problem Based Learning assisted with BUTIK was effective in mathematical problem solving’s ability of the students.

Abstract

The student’s learning process becomes a benchmark for student’s learning process in the school. The success of learning mathematics of 9th grade at SMP N 02 Paguyangan, Paguyangan District, Brebes Regency wich is still low, need further review tthrough coaching methods. One of the most important things in learning is the goal, with the aim of the student’s learning process more directed. Each student has their own goals or targets in learning so that, the benchmark of the successful of learning goal of each student is different. Student’s learning process give an effect for the the successful of learning’s students.
