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

Abstract

The use of Augmented Reality media is still rarely used in schools due to the lack of teachers’ innovation in classroom learning. Augmented Reality is a technology that combines three-dimensional real objects directly so that they can influence mathematical problem-solving abilities. The objective of this study is to determine the effect of the Augmented Reality-assisted Flipped Classroom model on students’ mathematical problem-solving abilities. This research is a quasi-experimental study with a posttest-only control group design. The population of this study consists of all students of class VIII. Samples are taken using the Cluster Random Sampling technique. The samples consist of experimental and control classes, each of which consists of 35 students. The description test given at the end of the study is used as a data collection method. According to the posttest results, the average problem-solving score using the Flipped Classroom model with Augmented Reality is 69.03, while the average score using the Flipped Classroom model without Augmented Reality is 58.97. This shows that students who use the Flipped Classroom model with Augmented Reality have better mathematical problem-solving abilities compared to the Flipped Classroom model without Augmented Reality. Therefore, there is an effect of using Augmented Reality media on mathematical problem-solving abilities.

Abstract

Students often find it difficult to understand the concepts in mathematics. Most of them find it difficult to concentrate and give up easily on understanding math concepts. Regarding this, the adversity quotient is very necessary for students. The adversity quotient is a student's internal factor in the form of persistence, responsibility, control, and views on dealing with problems. Memorizing the Qur'an is known to train a person to maintain peace of mind, concentrate easily, and control the emotions that exist within. The purpose of this research is to describe the ability to understand mathematical concepts and the adversity quotient of students in terms of their ability to memorize the Al-Qur'an. This research is a quantitative descriptive study with research subjects, namely class VIII students one of SMP Private at Binjai. Data collection techniques in this study used questionnaires, documentation, and interviews. Data analysis was carried out using descriptive statistics, namely narrating and describing the results of questionnaires and interviews. The results showed that the ability to understand mathematical concepts and the adversity quotient were influenced by memorizing the Qur'an. Religious subjects (SR) have the ability to understand high-level mathematical concepts and the adversity quotient of the climbers group. Superior Subjects (SU) have the ability to understand intermediate-level mathematical concepts and the adversity quotient of the camper group. Elementary Subjects (SD) have the ability to understand low-level mathematical concepts and the adversity quotient of the quitters group.

Abstract

The purpose of this research is to produce a product from the design of interactive learning media articulating the "BADANA" storyline. This study describes the feasibility of media resulting from the validation of material experts, media experts, and linguists. Furthermore, the response of teachers and students as users of the use of interactive learning media "BADANA". The model used is the ADDIE model which includes five stages including analysis, design, development, implementation, and evaluation. Furthermore, for the subject of this study, namely class III students one of SD Negeri in Sindanglaya. The feasibility of this interactive learning media resulted in that the percentage of assessments from material experts was 100% in the "Very Feasible" category, from media experts it was 96.1% in the "Very Feasible" category and from linguists it was 91.6% in the "Very Feasible" category. While the percentage of responses from teachers was 93.7% in the "Very Feasible" category, indicating that this interactive learning media can be used by students. After students used interactive learning media in field trials, student responses were in the "Very Feasible" category with a percentage of 95.9%. Therefore the interactive media articulate storyline "BADANA" can be used as an alternative in the learning process which can overcome the lack of interest of students when learning mathematics, especially on flat material and its properties.
