Abstract

Problem solving is an important part of learning mathematics, but the problem solving ability of students in Indonesia is still low. This study develops problem solving tasks in an Islamic context for junior high school students. Practicality was obtained through test questions on one-to-one and small groups of 22 (twenty two) students from several cities in Indonesia as well as analysis of student work results, questionnaires and interviews. The results of data analysis indicate that practicality Islamic context problem tasks have been obtained and have high validity and reliability so that the questions are feasible to use.

Abstract

This study aims to find out the mistakes made by students in solving the PISA model questions based on the Newman procedure. This research is a qualitative research. The research subjects consisted of 15 of ninth grade students SMP Karya Ibu Palembang. Data was collected by tests and interviews. The validity of the data was tested by using triangulation technique. The data were analyzed with data reduction, data presentation, and drawing conclusions. The results of this study indicate that there are errors made by ninth grade students in solving the PISA model questions. These errors include misunderstanding the problem, problem transformation error, process skill error and writing answer error. Therefore, to minimize the occurrence of errors, it is recommended that students understand the formula by being understood not memorized, learning is more related to everyday life to make it easier to understand and remember, and increase practice questions.

Abstract

This study aims to see the management of PQ4R learning in improving students' mathematical understanding. This research is an experimental study. The population in this study was grade VIII MTs Negeri 2 Way Kanan students, the sample in this study was taken by random class technique, by lottery which aimed to take samples that had the same ability so that 37 students of grade VIII A were obtained as an experimental class using the PQ4R strategy and class VIII B totaling 39 students as a control class using expository strategies. After learning in the experimental class and control class for five meetings, continued with data collection. In the data collection process, the author uses tests, documentation and data analysis consisting of pretest and posttest. The research method used to see the magnitude of the influence, data analysis is calculated using the normalized gain formula (N-Gain) then to see the magnitude of the influence a t-test is carried out. The results showed that the average N-Gain obtained by the experimental class was 0.61 while the average gain of the control class was 0.54. Based on the results of analysis and data processing using the t-test, tcount =  2.633 > ttable = 1.992, with a significant level of 5%. Since t counts > ttable then Ho is rejected. Based on these results, it can be concluded that the PQ4R strategy has a significant influence in improving the mathematical understanding of grade VIII MTs Negeri 2 Way Kanan students

Abstract

This study aims to obtain STEM-based LKPD for the EDP learning model developed for Geometry Transformation material, to determine the feasibility of LKPD, to find out students' responses to LKPD, and to find out the potential effect on students' creative thinking after using the LKPD. The subjects of this study were 3 teachers as material experts, 2 lecturers and 1 design expert teacher, as well as 25 class XI students of SMA IBA Palembang for the 2022/2023 academic year. The level of feasibility is seen from the results of the assessment of material experts and design experts. Meanwhile, students' responses were seen from the results of the questionnaire after using the STEM-based LKPD that had been developed. This study uses the ADDIE research model (Analysis, Design, Develop, Implement, Evaluation). Based on the results of the experts' assessment, it was obtained STEM-based LKPD that was feasible to apply to the Geometry Transformation subject. Student responses were obtained by 86,6% in the practical category. As for students' creative thinking skills, it was obtained that 84% of students completed the creative thinking test. The conclusion obtained from this study is that STEM-based LKPD on Geometry Transformation material is very suitable for use as teaching material. Keywords : LKPD, STEM, Geometry Transformation, Creative Thinking

Deaf children experience limitations in language and communication, so teachers in special schools are required to have a strategy in conveying mathematics material so that they can understand the material well. The use of learning media for deaf children can have an influence on children with hearing impairment so that abstract mathematical concepts and ideas can be studied, understood, and achieved by children's reasoning. This study aimed to explain the practicality of learning media fora flat rectangular puzzle. The research method used was development using a formative evaluation flow in terms of one-to-one and small group stages. The subjects in this study were 7 children in grade VIII SLB-B Karya Ibu Palembang. The instruments used were questionnaires, interviews, observation and posttest questions. From the results of the study, it was concluded that: producing learning media for a practical quadrilateral puzzle on the subject of practical jargar, the practicality of this media was seen from the comments and suggestions of children in the one-to-one and small group stages.
