Abstract

The purpose of this study is to find out how the analysis of the mathematical problem-solving ability of students in Mathematics of Natural Sciences (MIA) and Social Sciences (IIS) groups in terms of interest in learning the mathematics of learners. This research is a qualitative research type analysis. The data collected in this research is done by a triangulation technique which is done when the researcher analyzes the problem-solving ability of mathematical learners. The technique of data validity used in this research is triangulation technique. Data analysis techniques used are Model Miles and Huberman, IE data reduction, data presentation, and conclusion. The results of the discussion show students with high-interest categories can solve the problem of each of the stages of problem-solving correctly. Students with moderate interest categories in solving the given problem, able to solve problem problems and meet all the indicators, but in some other stages are still less systematic in the settlement. Students with low-interest categories are only able to finish in the stages of understanding the problem and planning the problem, although not maximal yet, and have not been able to finish the other stages.

Abstract

This study is based on the problems that occur in mathematics subjects, where most of the content is abstract, not a few students who find it difficult to learn. This should receive special attention from several parties, such as teachers, school environment, guardians, and the environment. because the subjects of mathematics is one of the mandatory lessons that must be studied all levels of primary and secondary education. This study aims to describe learning difficulties in understanding the anxiety of learners on learning mathematics class X in SMA Muhammadiyah 1 Kotaagung Tanggamus District. In this study population of 37 students with sampling technique in this study using purposive sampling and random class. Data collection in this research is a field data record using documentation, observation, questionnaire, and interview. Learning difficulties can be interpreted as a condition in the learning process characterized by the presence of certain barriers to achieve learning outcomes. In this study more mangacu on the subject of anxiety learners who become obstacles in achieving the objectives of learning .. This research is a type of qualitative research and validity techniques in this study using time triangulation. Based on the results of data analysis and discussion of learning difficulties in understanding students in learning mathematics can be concluded that the factors that affect learning difficulties are physical and physical factors and external factors that are family and environmental factors. Anxiety of learners with low anxiety category is more noticeable and very passionate in mathematics learning compared to the other two categories namely medium anxiety category and high anxiety.

Abstract

This research  aims to developing a cartoon-based mathematics learning media to reduce students' anxiety. The resulting product is a cartoon-based mathematics learning media using macromedia flash software for grade VII students of  SMP on social arithmetic material. This research uses  4D research and development method,  proposed  by Thiagarajan consisting of  4 stages: (1) define or define; (2) design or design; (3) develop or development  and (4) disseminate or  disseminate.  Researchers  use qualitative and quantitative data analysis techniques. This research uses data collection techniques which are based on a questionnaire in the form of Likert scale for student response and student anxiety. The result of the research is a cartoon-based mathematics learning media which is suitable for learning media to decrease students' anxiety.  The feasibility of  instructional media resulting from material experts and media experts is valid and worthy of use as a medium of learning. The students’ response to the learning media obtained in  small  group test  is very interesting with the average  score  of  3.52. In the large group test obtained, the criteria of attractiveness is very interesting with an average score of 3.41. Levels of students’anxiety after the use of learning media have decreased, ie in the high anxiety category it has decreased from 41% to 0%, in the medium anxiety category it has decreased fom 35% to 24%, in the low anxiety category it has changed from 24% to 76%.

Abstract

The objective of the study was to analyze the students' comprehension ability concept by using Graded Response Models (GRM). This research is a type of qualitative research with descriptive approach. The subjects of the study were students of class VIII of 6 people by purposive sampling. Technique of collecting data is done by written test (essay) and interview. Data analysis technique is using Graded Response Models (GRM) test, which is then combined with data reduction, data presentation, and conclusion. The results showed that students who have high ability category of 18.19%, 60.6% moderate students, and low-ability students 21.21%. This can be seen from the scores obtained from the students' ability to comprehend the concept of mathematical concepts, and obtained the graph of parameter estimation results by using Graded Response Models can be increased from the lowest ability of learners that is θ (-4) to the highest ability of learners ie θ (4) for each item item category.

Abstract

This research entitled Development of Mathematics Based Module of Ethnomathematics using Inkuiri method. This study aims to find out how the development of mathematics learning module based on ethnomathematics using inquiry method, and to know the teacher and student response to the development of mathematics learning module based on ethnomathematics using inquiry method. This research method is Research and Development (R&D) using 4D model. Based on the results of the validation of stage 1 by the material experts obtained a cumulative average of 65.36% with the criteria of "good enough" which means that there is an improvement of some aspects contained in the module. After performing a series of revisions, the average score of cumulative of 84.02% validation with "good" criterion was obtained, so there is no revision of the module. The average score of cumulative validation of stage 1 by a media expert is 60% with a "good enough" code which means that it needs to be revised in some parts of the module. In the second stage of validation, the average cultivation is 86.66% with "very good" criteria so that the module is valid and ready for a field trial. From the results of research teacher response to the module obtained an average of 86.15% with the criteria "very interesting". In the small group trial, the average of 85% was obtained with interesting criteria and large group trial obtained an average of 87.28% with very interesting criteria so that the module is feasible and ready to be used as teaching materials.
