Proporsi merupakan salah satu topik matematika yang mulai diajarkan di tingkat sekolah dasar. Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk mengetahui dan menggambarkan bagaimana siswa sekolah dasar kelas 5 memecahkan masalah kontekstual proporsi ditinjau dari perbedaan kemampuan matematika. Subjek penelitian ini adalah siswa kelas 5 SD yang terdiri dari kemampuan matematika rendah, sedang, dan tinggi. Instrumen penelitian yang digunakan adalah Soal tentang konsep proporsi. Hasil menunjukkan bahwa subjek dengan kemampuan matematika rendah tidak menggunakan konsep proporsi untuk menyelesaikan masalah terkait perbandingan. Subjek tersebut hanya membandingkan antara kuantitas yang satu dengan kuantitas yang lain secara langsung. Subjek dengan kemampuan matematika sedang mampu menggunakan konsep proporsi untuk menyelesaikan masalah terkait perbandingan. Akan tetapi, mereka belum menunjukkan alasan yang kuat dalam hal membandingkan tiga buah kuantitas. Subjek dengan kemampuan matematika tinggi mampu menggunakan konsep proporsi untuk menyelesaikan masalah terkait perbandingan. Subjek tersebut mampu membandingkan ketiga kuantitas dalam masalah yang diberikan.

The present research is the preliminary part of a large-scale design research aimed at supporting students to use effective strategies and to reach multiplication concept by designing instructional activities in the topic of multiplication principle covering two-dimensional as well as three-dimensional problems. They were conducted in two cycles of which 10 to 11-year-old elementary school children actively participated. Design research then was chosen to reach the set goal. Specifically, in each cycle, hypothetical learning trajectory was set by applying the principle of Realistic Mathematics Education. Reflecting on the activities of both cycles, the findings suggest that by creating hands-on activity, the students are able to make all different possible combinations of each kind of object. Besides that, stemming from pairing one object to the other kind of objects, the students are simplified to use efficient strategy for the next increasingly complex problems. The increasing number problem facilitates students to grasp the use of multiplication in solving the problems. However, the understanding of students in multiplication should be firmly established by the guide of the teacher since they just made inductive reasoning of the solution patterns of the problems

The application of fast calculation techniques in supporting the learning mathematics in this training activity aimed to increase the understanding of elementary school mathematics teachers about the fast calculation method that can be applied in basic algebraic calculation. The implementation of this activity was expected to improve the quality of Elementary School Mathematics education in Takalar Regency. This training used demonstration and question-and-answer methods about the fast calculation technique performed by elementary school teachers in Takalar Regency. The implementation of this activity began with observations and interviews with the Head of the Teacher and Education Personnel Division at the Takalar Regency Education Office. This activity was carried out by Syncronouse Online using the Zoom meeting application due to the Covid-19 Pandemic. There were 33 participants who attended the training. Based on the results of a questionnaire on the teacherâ€™s perceptions about the use of fast calculation techniques, all teachers find this technique helpful. Therefore, the teachers will use this technique in teaching arithmetic to their students.

This study aims to determine the Effectiveness of the Cooperative Learning Model with Group Advisory Strategy in Mathematics Learning of the Grade VII SMP. This research is pre-experiment with techniques sampling is cluster random sampling. Data collection was carried out using observation sheets of implementation of learning, test results of learning (pretest and posttest), observation sheets of student activities, and student questionnaire responses. The data analysis technique used is descriptive and inferential statistical analysis. The results of descriptive statistical analysis showed: (1) The average score of learning outcomes after learning reaches 80.04 with standard deviation of 8.79, (2) the posttest results show that classical completeness is achieved 91% (3) The average percentage of student activity is 89% (4) the average percentage of students who gave positive response 89%. The results of inferential statistical analysis showed : (1) The average value of students taught using cooperative learning models with the Advisor Group Strategy is greater than completeness, which is 70, and (2) The proportion of classical completeness of learning outcomes after the application of the cooperative learning model with Group Advisors Strategy achieve classical completeness. From the results of this research it can be concluded that cooperative learning models with the Group Advisory Strategy are effectively used in students of grade VII.

This research is a descriptive research with qualitative approach. The purpose of this research is to describe the cognitive level of UTS and UAS made by teacher Mathematics class VII. The subject is midterm exam and final exam class VII created by the mathematics teacher according to curriculum 2013. This Data analyze based on three levels of cognitive, namely (1) Level 1 knowing in the form of cognitive processes, remembering and understanding, (2) Level 2 applying in the form of cognitive processes, cognitive processes applying, and (3) Level 3 reasoning cognitive processes analyzing, evaluating and creating. Generally cognitive levels distributed in a comprehensive way so that educational evaluations measure educational attainment. The data also obtained using classification paper of level cognitive, interview guidelines and expert validator. The results showed that subjects are dominated by the level of knowing with a percentage of 50% by 10 items in the cognitive processes of understanding. While the level of application with a percentage of 45% is 9 items in the cognitive process of applying and the level of reasoning with a percentage of 5% is 1 item of the cognitive process analyzing.
