Pembelajaran Luas Segiempat untuk Siswa Kelas VII Menggunakan Reallotment Activities
Full text linkThis research uses reallotment activities that already designed by previous research to know the role of reallotment activities in great rectangular learning. This research uses descriptive research method implemented in class 7th at SMP N 3 Banguntapan, Bantul, Yogyakarta. The data collection techniques used are documentation, observation, and test. Furthermore, the researcher analyzed the data obtained through video recording, observation, and student test answers. The results show that reallotment activities can assist students in finding the square formula by changing the shape of a rectangle into a rectangular shape. The learning activities that use reallotment activities consist of action comparing the area of ??an irregular shape, replacing the regular form into squares, determining the area of ??the rectangle and the parallelogram, finding the formula of the breadth of the parallelogram, and also determining the area of ??the trapezium, the parallelogram, and kite
Belajar Pencerminan dengan Menggunakan Permainan Bom-Boman di Kelas VII
Full text linkThis study produces a learning trajectory in transformation geometry, specifically on reflection using a game called “bom-boman”. This study using PMRI, the Indonesian version of realistic mathematics education. Subjects of this study are 36 seventh grade students of SMP Negeri 24 Palembang. This study using a design research approach with conducted in three stages: preliminary design, the design experiment (pilot experiment & teaching experiment), and retrospective analysis. Data were collected by observations, interviewing the student, collecting student worksheet, and documentation of classroom event and group works. Hypothetical Learning Trajectory (HLT) has been designed then compared to Actual Learning Trajectory (ALT) during the learning process. Retrospective analysis shows that student’s learning trajectories using the game help students to understand transformation geometry in reflection
Pengembangan Media Monopoli Matematika pada Materi Peluang untuk Siswa SMP
Full text linkThis study aims to develop Monopoly Mathematics Media (Monomath) to learning mathematical probability exercises at junior high school. Using the ADDIE model consist of five phases - Analyze, Design, Development, Implementation, and Evaluation to develop this Monomath Media. This Monomath has gone through validity, practicability, and effectiveness test. The result of this research showed that the Monomath obtained a total average score for all aspect were 78.1% of validity matter expert and 80.8% of validity media expert, which means the media is valid. In the feasibility, the study result obtained a total average score for all aspect was 82.5%, which means the media has met practical criteria. The field trials result were obtained an average score of 95.46 for the posttest. It is higher than pretest average score was 54.83. The result of the student questionnaire showed that an average score of 90% which means the student give a positive response to the Monomath they used. Thus, the result of Monomath to learning mathematical probability is valid, practical, and effective
Pengaruh Penggunaan Bahan Ajar Berbasis Android dan Tipe Kepribadian Terhadap Kemampuan Komunikasi Matematis Calon Guru
Full text linkThis research aims to determine the effect of using an android application compared to conventional teaching materials on Trigonometry courses on the mathematical communication skills of student candidates regarding personality type. The research method was used quasi-experiment with the population of first grade at Department of Mathematics Education of STKIP Santu Paulus Ruteng and the sample was taken from 2 classes. Data were through by questionnaires and mathematical communication test which were then analyzed by two-way ANOVA test. Data analysis and interpretation showed that: (1) students who were taught using the help of Android-based teaching materials had better mathematical communication skills than students taught conventionally; (2) there was an interaction between learning media and personality type on mathematical communication skills. The findings point to recommendations that the use of appropriate instructional media could be used to improve students' mathematical communication skills and would facilitate the learning process of mathematics
Desain Didaktis Bahan Ajar Matematika SMP Berbasis Learning Obstacle dan Learning Trajectory
Full text linkThis study is to correct mathematical learning by didactic design based on learning obstacles and learning trajectory. This is a qualitative study through Didactical Design Research (DDR) by three analytical phase, i.e. 1) didactical situation analysis before learning presented as didactical design hypothesis including ADP; 2) metapedadidactical analysis which analyzes teacher’s ability such as unity, flexibility, and coherency in learning; 3) retrospective analysis which is the correlated analysis between the result of didactical situation hypothesis analysis and metapedadidactical analysis. The result of problem analysis related to integer arithmetic operation, a concept of function, and two triangle similarity concept, implementation of early didactical design could predict probable mistakes done by students and even if the mistakes still there, it was decreased compared to early learning obstacle test. These conditions were reinforced after learning with mathematics score school succeed standard 75% was done
Model Problem Based Learning, Guided Inquiry, dan Kemampuan Berpikir Kritis Matematis
Full text linkThis research aims to determine differences in mathematical critical thinking skills between students who obtain mathematics learning using Problem Based Learning (PBL) and Guided Inquiry model. The research method used quasi-experimental with matching-only posttest-only control group design which implemented in one of the Junior High School of Yogyakarta. The instrument used is a valid test instrument namely posttest with descriptive evaluation. The result of this research showed that there is a difference of mathematical critical thinking skills between students who obtain mathematics learning using PBL model and students who obtain mathematics learning using guided inquiry model. Furthermore, the average of mathematical critical thinking skills between a student who obtains mathematics learning using problem based learning model is higher than students who obtain mathematics learning using guided inquiry model

Pembelajaran Pecahan dengan Menggunakan Manik Susun
Full text linkThis study aimed to design a learning path which can help students to understand fractions based on Pendidikan Matematika Realistik Indonesia (PMRI) approach. The subject is 30 students of 4th grade of PP Qodratullah Langkan. Method of this research is design research, Hypothetical Learning Trajectory (HLT) developed from learning activity series using context stacked beads. The implementation of this research in 3 stages: preparing the design experiment, conducting the learning (the design experiment), and retrospective analysis in order to contribute to Local Instruction Theory support to students in studying fractions. The designed Hypothetical Learning Trajectory (HLT) is then compared to Actual Learning Trajectory (ALT) students during the learning to analyze whether students learn or not from what has been designed in the learning sequence. A retrospective analysis of the implementation of learning suggests that the use of the stacking bead context can help students understand fractions
