Abstract

Students often make mistakes in solving problems are the function of misconceptions, miscalculations and errors procedure. That's because students do not have the ability to understand the concepts, capabilities in the calculation and the ability to understand the procedure better. This research aims to determine the percentage of types of misconceptions, miscalculations, and procedural errors function procedure eighth-grade students of SMP Muhammadiyah 2 Godean the academic year of 2016/2017. The research was conducted at SMP Muhammadiyah 2 Godean in class VIII C that all students totaling 32. The selection of research subjects taken on the recommendation of teachers, selected class VIII C because this class has an average mathematics achievement is low. Data collection techniques in this research using the test method and the interview method. The instrument used was a problem in narrative form as much as 6 questions and interview guides students. The data analysis technique used is descriptive qualitative analysis techniques to identify each type of mistakes made by the students. The results show the average percentage of misconceptions made by students of 82,292% (very high), the percentage of miscalculations made by the students of 42,708% (medium), and the percentage of procedural errors made by the students of 67,708% (high ). Mistakes made by students of class VIII C SMP Muhammadiyah 2 Godean relatively the same: there is no answer, wrong in understanding and translating the question, in applying the formula to resolve the matter, one to operate the calculations, one in determining the final outcome, not coherently in writing step completion, incomplete in writing steps to resolve and does not use logical reasoning to draw conclusions

Abstract

The dressing of students disciplinary at IX grade of MTs Muhammadiyah 2 Kalibening Banjarnegara in the Academic Year of 2016/2017 and to know the contribution of the student in mathematics learning at grade IX of Islamic Junior High School (MTs) Muhammadiyah 2 Kalibening 2 Banjarnegara in the Academic Year of 2016/2017. The type of this research was qualitative by wing purpose sampling. The subject was collected from IX-A. The data was collected using observation and questionnaire. Content validation was used to analyze the instrument of the research. The research was analyzed by using the descriptive qualitative method. Barect on the result of the research, the researcher concludes that the method is learning on a tribute by improvising the students' learning discipline at IX grade of MTs Muhammadiyah 2 Kalibening Banjarnegara Academic Year of 2016/2017. It was shown by the achievement which students got before and after giving an action. The students' average score was 55, and into 57,67, re-teaching affected the low classroom. The middle classroom had an average score of about 60,33 at first and turned into 62,58 because it was given action. The improvement of student's disciplinary learning was contributed by conventional learning. Next, the full classroom about 70,2 before getting action. After giving an action, it increased by about 72. It can be concluded that the improvement of student's disciplinary learning was contributed by learning methods. The re-teaching learning method is contributive because it showed that the full classroom's improvement affects the bottom classroom.

Abstract

The problem that underlies this research is the low value of learning outcomes of students, especially in class VII D. This study aims to improve the learning outcomes of students by using a realistic mathematics education approach to students of class VII D in State Junior High School (SMP Negeri) 2 Bambanglipuro even semester 2017 Academic Year / 2018. This study includes Classroom Action Research (CAR). The research was conducted in two cycles. Each cycle consists of two meetings. Data collection techniques used are interviews and tests. Data analysis used is data reduction, data presentation, conclusion, and verification. The indicator of the success of this study is the achievement of increased learning outcomes of students. Learning outcomes of students are obtained from the work of solving the description questions. This success is shown by students' learning outcomes achieving an average good category (≥ 61%). Based on the study results using a realistic mathematics education approach in the quadrilateral sub-topic, there is an increase in students' learning outcomes. This is evident from the first cycle test results to the second cycle test, which has increased by 1.76%. In the first cycle, the average test results of students were 42.47. In the second cycle, the average test results of students were 43.22. However, there has been an increase in learning outcomes but has not met the indicators of success.

Abstract

In SMP Negeri 3 Sentolo, the learning activities tend to teacher learning-centered, it causes boredom and tiring of students. This can affect student learning results. One can be applied to solve this problem as an alternative learning model is a cooperative learning model NHT type and Talking Stick type. Therefore the purpose of this study is to determine the effectiveness of cooperative learning model NHT type and Talking Stick type of VII students in SMP Negeri 3 Sentolo Kulonprogo on even semester in the academic year of 2015/2016. The population in this study were all students of class VII SMP Negeri 3 Sentolo Kulonprogo academic year 2015/2016. That is consisting of six classes with 168 students. The samples were taken two classes used random technique sampling for each class. It is obtained VII A as the experimental class I and VII C as the experimental class II. The data analysis technique used a prerequisite test. It includes a normalized test, homogeneity test, and hypothesis test of two parties and one party. Based on the calculation of the two parties hypothesis test with significance level a = 5% and 56 degrees of freedom obtained value  and  so ,  then accepted H0 means there is no difference in the students' mathematics learning result which uses cooperative learning model NHT type and Talking stick type. On the other hand, for one party  hypothesis test with significance level a = 5% and 56 degrees of freedom is obtained  and  so , then accepted H0 it means both cooperative learning model NHT type and Talking stick type no more effective than the other one.

Abstract

The use of media in mathematics learning is used to assist students in understanding learning materials. The background of this development research is the absence of media that used in mathematics learning at SMP Muhammadiyah Seyegan and SMP Muhammadiyah Kasihan besides textbooks and worksheets as a learning resource. The purpose of this study was to develop learning media stop motion animation based on material tangent to the circle and to determine eligibility based on the assessment of experts and the students' responses. This research, the method used is Research and Development method. The subjects were expert lecturers, subject teachers, and students in grade VIII SMP and SMP Muhammadiyah Seyegan and SMP Muhammadiyah Kasihan. The object of this study is the learning media stop motion animation in the material tangent to the circle for grade VIII Junior High School. The stage of collecting data through direct observation, interviews, and questionnaires with research instruments such as questionnaires. The data analysis technique used is the analysis of qualitative data. The results showed that the developed learning media are included in the category of very decent (ideals percentage of 85.98%). Judging from the aspect of media, materials, and instructional media student responses are developed each get an average score of 89.5 respectively (criterion ideals 85.6%), 71.5 (percentage ideals 89.38%), and 57.85 (percentage ideals 82.64%). Thus mathematics learning media stop motion animation based on material circle tangent to class VIII SMP fit for use by students and teachers as a learning medium.
