Abstract

Mathematics learning is expected to be linked to culture, known as Ethnomathematics. Although ethnomathematics-based teaching materials can be found in modules and worksheets, there are few ethnomathematics-based questions on the specific material, particularly relations and functions. This research aims to generate valid and practical ethnomathematics questions for the material on relationships and functions. Tjeerd Plomp's research and development methodology was used in this study, which consists of three stages: preliminary research, prototyping, and assessment. The participants in this study were eighth-grade Islamic junior high school students. This study's instruments included interview sheets, questionnaires, and tests. The validity and practicality of the product are the product's evaluation criteria for development. The validators declared the questions valid based on a validity criterion greater than 0.9 based on the validation. As a result, the questions are valid regarding content, language, and culture. Furthermore, the analysis demonstrates that the questions developed meet practical criteria. The student practicality questionnaire data analysis revealed that each indicator's percentage ranged between 82.14% and 92.8%.

Abstract

This descriptive-qualitative study aims to discover factors that influence students' difficulties in solving non-routine problems. The researchers employed open-ended questions that had previously been developed by researchers, ensuring that they were valid, practical, and had potential effects. The researchers brought up this topic because non-routine questions can help students improve their mathematical skills. The study's approach consisted of three stages: preparation, implementation, and data analysis. The research subjects were 31 eighth-grade students from one of Belitang's junior high schools. Data was gathered through observation, interviews, and testing. Observation was utilized to collect data on the learning process, while interviews were used to understand more profoundly and directly about students' difficulties in addressing non-routine tasks. The test was then administered to assess students' ability to solve non-routine tasks. The data was evaluated qualitatively using descriptive analysis. Based on observation and interview data, several factors contributed to students' difficulty in solving non-routine problems, including the fact that students had never worked on non-routine problems during the learning process in class, and the teacher's book only contained routine problems. In relation to the foregoing, the exam results show that students' ability to solve non-routine problems remains poor, with as many as 58.07% receiving poor grades, 19.35% receiving moderate grades, and only 22.58% receiving good grades. With this research, it is envisaged that teachers will assign numerous non-routine tasks in class in the future, allowing students' mathematical abilities to be thoroughly developed.

Abstract

This study aimed to find out the ability to solve math problems in solid figures topic before flipped classroom type blended learning was applied to grade IX students of SMPN 2 Sokaraja in the 2019/2020 school year and to know the influence of flipped classroom type blended learning on the problem-solving skills of solid figures topic in Grade IX of SMPN 2 Sokaraja in the 2019/2020 school year. By looking at the objectives, statistical testing was conducted to test the effectiveness formulated in the research hypothesis. To test the significance of mean differences over two different groups due to the use of multiple treatments on an independent variable can be done with a parametric statistical test using the -t-test. Before conducting parametric statistical tests, the data we obtained must fulfill the requirements of conducting tests with parametric tests including, normal and homogeneous distribution. If the data meets the requirements of a hypothesis test with a parametric test, but if it does not meet the requirements then the hypothesis test is conducted with a non-parametric test. The previous analysis resulted that the problem-solving skills of students taught with a blended learning model flipped classroom type are better than conventional learning models. Descriptively, when viewed from the average score of overall math problem-solving skills for students taught with a blended learning model flipped classroom type was 44.22, while those taught with conventional models was 38.17. From the average of each level of math problem-solving ability, the one taught with a blended learning model flipped classroom type was 4.42 and the one taught with conventional learning model was 3.82. It was explained, that the model of learning blended learning type flipped classroom was very influential on the ability to understand problems, the ability to plan solutions, the ability to complete, and the ability to re-examine the results of work
