Abstract

This research aims to analyze learning outcome of grade X students in one of the Public Senior High Schools in Cimahi on the subject of irrational inequalities, using the learning method of flipped learning. Research method used is classroom action research and the subjects being researched are 18 students of grade X IPA. On the first cycle, conventional learning method is used, continued by the second cycle, which used flipped learning model. The data collection technique is using observation, documentation, and 4 essay test question that suitable with indicator of competence achievement. Improvement of learning outcome are then reviewed frommstudents grades in comparison with the school’s KKM on the first as well as the second cycle. In conclusion, there are 61% of student who do not pass the KKM on the first cycle, however by using the flipped learning model on the second cycle, there are only 22% of students who do not pass. It shows that the model gives a better influence toward students’ learning outcome compared to the convensional learning model.

Abstract

This study aims to analyze the difficulties of students in working on questions about opportunities in class IX Middle School students in one school in Nagreg. The research method used is a qualitative description method. The study was conducted with a sample of 27 students. The test questions given are in the form of 6 descriptive test questions that have a cognitive level based on Bloom's Taxonomy that has been validated both in content and empirical. Data processing techniques namely through data tabulation, then calculating of percentages and comparing the results of calculations with criteria. The results of the study state that students find it difficult to determine the empirical opportunity of an experiment and determine the sample space of an experiment at a high cognitive level (C6). Difficulties arise because students are unfamiliar with the concept, students do not understand the material, have not been able to conceptualize and analyze correctly, also weak mastery and understanding of existing concepts. So this indicates that there are still many students who have difficulty in solving the problem opportunity.

Abstract

The following research relates to the use of problem based learning (PBL) models in mathematics learning aimed at increasing student learning motivation. The subjects in this study were students of class XI in one of state vocational schools in Cimahi. Questionnaires and observation sheets as instruments used in this study. Research is carried out a number of two cycles, each cycle for one study, each cycle there are four main activities, namely planning, implementation, observation and reflection. The data collection technique in this study used questionnaires and observation sheets. The data analysis technique is descriptive qualitative, so that research results are obtained that show that there is an increase in student learning motivation in each cycle.This can be seen from the increase in students' positive motivation obtained from the questionnaire given. Because learning with a problem based learning (PBL) model has characteristics that are able to make students easily understand the material conveyed and motivate students to learn mathematics for the better.

Abstract

The purpose of this research is to find out students' mistakes in solving algebraic operations according to Kastolan's theory. In this study used a qualitative descriptive method with the research subject of class VII in one of the MTs in West Bandung Regency with a total of 20 students consisting of 9 girls and 11 boys. The data collection technique was carried out in the form of a written test consisting of 5 description questionsFrom the results of the analysis of student errors based on Kastolan theory, there are several types of Kastolan errors overall, namely: 1) the type of conceptual error is 60%, this type of error is included in the high category 2) the type of procedural error is 40%sufficient category and 3) the type of technical error by 30% this type of error is included in the low category. Based on the results of the analysis that has been obtained from students' answers, the cause of the errors that exist in each of these errors is an error in making mathematical models, students do not show completion strategies and students' lack of ability to perform arithmetic operations.

Abstract

Learning abilities that are elements of learning in the 21st century require teachers to have skills in guiding students to develop communication skills, process information, think creatively, solve problems, collaboration and manage themselves. These abilities can be developed through the implementation of innovative learning in the classroom, one of which is the STEM approach. STEM-based learning integrates four fields, namely science, technology, engineering and mathematics in one learning activity. This service activity was carried out by 30 mathematics teachers who were members of the Mathematics teacher community in Denpasar City. The activity is carried out using the Asset Based Community Development (ABCD) method. The service activities that have been carried out have a good impact on teachers. At the end of the activity, teachers can understand STEM-based mathematics learning through practical learning activities and are able to develop learning innovations by compiling STEM-based learning scenarios.
