Abstract

This study aims to produce products in the form of LKPD SPLDV material, and Know the response of educators to LKPD on SPLDV material. The method of this research is Research and Development (R & D) based on ADDIE model Stages performed only from stage 1 to stage 5 that is from analysis, design, development, implementation, evaluation. The result of the material expert test on the content quality aspect obtained the average score of 3.67 with very good criteria, on the aspect of the accuracy of the scope obtained the average score of 3,167 with good criteria. Expert test media on LKPD size aspect got the average score 4 very interesting, skin design aspect LKPD got average score 3,66 with the good criterion, design aspect of LKPD got average score 3,4167 with good criterion. Expert tests obtained an average score of 3.22 with good criteria. In the small group trial of students in the attractiveness, test obtained an average score of 3.57 with interesting criteria, large group trials of students in the attractiveness test obtained an average score of 3.56 with interesting criteria. From some of the above data, it can be concluded that LKPD developed into good criteria and get a good response for the learners.

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 aims to produce swed max edutainment based instructional media through metaphorical thinking approach to understanding mathematical concepts of trigonometric material. This research method used stages of Borg and Gall model development modified by Sugiyono with the aim to create a specific product and test its effectiveness. The results showed that the development of learning media has very good criteria with the average assessment of material experts of 88.8% and media by 85.7%. In the attractiveness, the test has very good criteria in small groups average percentage of 88.4% and field trials 89.6%. Learning media also affect the understanding of mathematical concepts of learners evident from the test results before and after showed improvement indicators of mathematical concepts from low to high category. The conclusion of this research is developed instructional media have very good criteria and improve understanding of the mathematical concept of learners.

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.
