Abstract

Studi ini bertujuan untuk menganalisis cara pemahaman dan cara berpikir siswa MAN dalam menyelesaikan masalah yang melibatkan persamaan lingkaran berdasarkan teori Harel. Riset ini memanfaatkan pendekatan kualitatif deskriptif dengan metode fenomenografi untuk mengungkap perbedaan WoU dan WoT siswa dalam menyelesaikan masalah terkait persamaan lingkaran. Instrumen pengumpulan data yang digunakan yaitu tes persamaan lingkaran, serta wawancara klinis. Riset ini dilaksanakan di salah satu MAN di Jakarta Timur pada semester genap 2020/2021. Subjek riset berjumlah 28 siswa kelas XI MIPA 3. Hasil penelitian menunjukkan bahwa cara berpikir siswa dalam menyelesaikan masalah persamaan lingkaran dipengaruhi oleh cara memahami konsep yang telah siswa pelajari. Cara memahami konsep yang salah atau tidak utuh menghasilkan cara berpikir yang tidak logis atau salah. Begitu pun sebaliknya, pemahaman yang baik mengenai persamaan lingkaran akan menghasilkan penyelesaian dari cara berpikir yang sistematis, ekeftif, dan logis. Dengan demikian, teori Harel mengenai duality principle berlaku terhadap siswa dalam menyelesaikan masalah terkait persamaan lingkaran.

Abstract

One of the psychological aspects of students that encourage students' mathematical representation ability is self-confidence. The mathematical representation ability of each student is not the same, because of the student's ability to receive and process the information that the teacher has given during the lesson. Thus, the cognitive style also affects the ability of mathematical representation. This article is a systematic literature review (SLR) of 25 studies published until November 2022 with the help of the Publish or Perish (PoP) application with the Google Scholar database. This article aims to investigate: (a) the characteristics of the period, index, research approach, subject matter, and demographics of the participants in the identified articles, (b) learning methods that can improve students' mathematical representation and self-confidence abilities, and (c) the most frequently used cognitive style type. The results of research with SLR show that the Problem-Based Learning (PBL) learning model is effective and able to develop students' mathematical representation skills, and student self-confidence. Mathematical representation ability studies based on cognitive style mostly use Field Dependent (FD) and Field Independent (FI) types, and rarely use spatial and visualizer-verbalizer types. The results of this SLR can be useful for other researchers who are interested in researching this topic in the form of research gaps that can be done for the next research.

Abstract

The dedication activities in SD Negeri Cihanjuang 2 aimed to introduce students to animated learning videos they did not get before in class. Animation-based learning video contains whole-number four basic arithmetic operations consisting of addition, subtraction, multiplication, and division operations. In addition, the activity also used the evaluation of Crossword Puzzle quizzes and images they commonly find in everyday life to help students visualize abstract mathematical problems. The target of this activity is students-class VI SD Negeri Cihanjuang 2, which has 23 students. The six stages carried out in this activity, namely the preparation stage, group division stage, delivery of material through animation-based video learning and emphasis on the concept of whole-number operations stage, giving the Crossword Puzzle quizzes stage, discussion stage, and evaluation stage. Based on the observations, many students showed interest and positive responses in listening and paying attention to learning videos and actively asking and discussing during solving quizzes and discussing topics.
