Abstract

Multiple representations have an essential role in the mathematics learning process for the students, pre-service and in-service teachers. It is important for them to understand the concept of mathematics and mathematical problem solving particularly in word problem-solving. However, pre-service teacher and in-service do not fully notice of using a variety of representations in the learning process. Thus, the purposes of this study are intended (1)  to find out the type of multiple representations used by pre-service teachers to solve the word problem by their own,  and (2) to figure out how they teach the process of word problem solving to the students. The participants of this research were the sixth-semester students of the Mathematics Education Program. Their written responses were analyzed and interviewed (semi-structured interview). The result showed that the types of multiple representations used by pre-service teachers are symbolic and verbal representations. Different multiple representations are used to help the student in word problem solving, even though pre-service teachers did not fully aware to apply them in their teaching activity. Hence, sharing the knowledge and the usage of multiple representations for pre-service mathematics teachers are urgently required in the real classroom setting.

Abstract

Developing a problem-solving skill for important things which need to be paid attention is how the students' thinking process in solving a problem is. Thinking about what is thought in this term relates to students' awareness of their ability to develop various ways which may be taken in solving a problem is known as metacognition. The existence of metacognition is very important for students in solving mathematical problems. This is a qualitative study using the grade VII students having medium ability as the subjects. The results of the study obtained that through intervention conducted by the researchers in 5 meetings, metacognition capability emerged in the subjects so that with their own ability they are able to solve mathematical problems provided.

Abstract

The purpose of this study was to describe the initial conception of prospective teachers about creative thinking in mathematics. This research used a qualitative research method. The Research was conducted at private universities in Semarang, held in the second semester of the academic year 2016/2017. The subjects were six students of the seventh semester. This research used two instruments; test to explore the concept of creative thinking and interview. This study provides findings that there are similarities in the concept of prospective teachers in mathematical creative thinking. The prospective teacher's conception of the creative thinking of mathematics leads to the emergence of new concepts or ideas in completing mathematical problems based on experience. The appearance of the new idea in question is to solve a different problem from the existing procedure and solve the problem with a different perspective that is still logical. The prospective teacher's said that it was necessary for prospective teachers to understand the concept of creative thinking in mathematics to solve mathematical problems from various perspectives based on his learning experience.

Abstract

This research aims at describing students? statistical reasoning in graphics statistics representation related to distribution. The subjects of this research were students of semester IV of Program of Study Mathematics Education of Muhammadiyah University Ponorogo who have taken a basic statistics course. These subjects were chosen because they have taken a course related to descriptive statistics which discusses graphics representation and data distribution. The data collection technique used essay test related to graphics representation. In addition, an interview was also conducted to confirm students? answer. This research finding shows that statistical reasoning of semester IV students of Mathematics Education whose statistics ability is poor belong to pre-structural level and whose statistics ability is high belong to multi-structural and relational level. The high skilled students could conclude the data with statistical reason even though they used informal terms. Students with multi-structural and relational level regard that variety is a standard showing the numbers of different data among others, not on the different value from the average. Students with relational reasoning level were able to generate graphics concluding by connecting the central tendency and distribution scale.

Abstract

Abstract: This study aims to describe the thinking process of field dependent students in solving geometric problems based on the Polya stage. The type of research used was descriptive qualitative. The study was conducted at SMA 1 Pasuruan using 2 subjects in the cognitive style FD taken from 38 students. The instruments used were in the form of cognitive style exams, solving geometrical problems and interview guidelines. The results of the study show that in processing information, the subject of FD does not understand the problem as a whole so that in planning the completion of the subject FD forgets about the concept of the cube. Abstrak: Penelitian ini bertujuan untuk menggambarkan proses berpikir siswa field dependent dalam menyelesaikan masalah geometri berdasarkan tahapan Polya. Jenis penelitian yang digunakan adalah deskriptif kualitatif. Penelitian dilakukan di SMA Negeri 1 Pasuruan dengan menggunakan dua subjek bergaya kognitif FD yang diambil dari 38 siswa. Instrumen yang digunakan berupa eksamen gaya kognitif, penyelesaian masalah geometri dan pedoman wawancara. Hasil penelitian memperlihatkan bahwa dalam memproses informasi, subjek FD tidak memahami masalah secara utuh sehingga dalam merencanakan penyelesaian subjek FD lupa tentang konsep kubus.
