Abstract

This research was conducted to proposepre-service elementary teachers? (PsET)written communication in explaining multiplication representation, especially using area representation. Communication has an important role in learning process. Through communication, one can show or confirm his or her knowledge. The subjects of this research were 9 university students as the PsET. The subjects were asked to write the explanation of multiplication using area representation on a paper. After that, the researcher confirmed it by asking the subjects to re-explain that mentioned representation on a board as if they really taught elementary school students. From the result of this research, it is identified three main findings that can be obtained from written communication of the PsET, they are 1) expressing procedural and conceptual knowledge, 2) expressing ability in constructing connection, and 3) improvingthe confidence of PsET.

Abstract

The main objective of this research will implement the onto-semiotics approach to analyse the conceptual of mathematical meaning in a modelling context corresponding to their use of the mathematical objects. Semiotics functions and mathematical object that emerged when solving mathematical modelling will be highlighted according to OSA. Students responses to modelling questions were used to classify the semiotics function that relates to the different mathematical objects.

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

Students ability in making mathematical connection is one of the key goals in mathematics education. This study describes obstacles to students’ productive connective thinking in solving mathematical problems. Obstacles experienced by the students when solving mathematical problems were identified based on connective thinking networks completeness according to Thosio’s thinking scheme. Think aloud protocol worksheet and recording were analyzed descriptively. In solving mathematical problems, students faced obstacles in every thinking stage. They were unable to make a complete connective thinking network in cognition, formulation, reconstruction, and inference stage.

Abstract

This study aims to explore students’ proportional reasoning in solving multiplicative problems on products of measurement type. Three 8 grade students of Public Junior High School 21 Malang were being purposively studied. The sampling technique is also called as the judgement sampling. Data then was being analyzed in three steps: data reduction, data presentation, and conclusion drawing/verification. The data were studied and analyzed based on Bexter’s and Junker’s Constructions of Proportional Reasoning theory consisting of five stages: (1) qualitative; (2) early attempts at quantifying; (3) recognition of multiplicative relationships; (4) accommodating covariance and invariance, and (5) functional and scalar relationships. Result shows that students with low capability (S1) solved problems by registering the number of first measurement then pair it with second measurement by summing the two measurements identified as early attempts at quantifying phase. It is also found that students with moderate capability (S2) solved the problem by registering all existing possibilities and then summing them all, concluding them qualified as being in recognition of multiplicative relationships phase. Moreover, students with high capability (S3) solved the problem by listing the number of the first measurement then multiplying it with the second measurement, qualifying them as being in the accommodating covariance and invariance phase in proportional reasoning.

Abstract

It is revealed that as a compulsory mathematic subject for junior high school students, most students are struggling to solve geometric problem. As an effort to fix this condition, this article describes mistakes of junior high school students’ structural thinking in solving geometric problem. Subjects’ mistake were assessed by Subanji’s (2015) theory of conceptual construction mistake and mathematical problem solving. Researcher then defragmented subjects’ thinking structure in order to solve problems effectively. The result shows that subjects experienced miss logical construction and construction gap. Miss logical construction occurred because students’ logical mistake in solving the problem, while the construction gap happened due to certain incomplete schemes in subjects’ problem solving thinking structure. Defragmenting was conducted by assessing mistakenly constructed scheme. Then, unconstructed scheme was revealed. When scheme had considered as sufficient, the constructed scheme were knitted into an interconnected scheme and subjects’ thinking structure became complete. Decomposition of incorrect structured schemes used cognitive conflict, while scheme and scheme knitting applied scaffolding.

Abstract

Mathematics is not only related about how to solve problems and provide conclusions, but also as a tool to communicate ideas clearly, precisely and briefly. Through mathematical communication, the teacher can see students'abilities in solving problems. The purpose of this research is to describe the mathematical errors of reflective student communication in solving open-ended problems. The research subjects consisted of 5 students of Boyolangu 1 Junior High School who had reflective cognitive style. Data collection is done by combining the results of data of  mathematical communication test and interviews. The mathematical communication test given is related to triangles and quadrilateral material. Test results were analyzed using mathematical communication indicators, namely: (1) giving clear responses, (2) making diagrams / sketches, (3) communicating mathematical ideas effectively to others, and (4) presenting logical arguments that support answers. The results of data analysis show that students only write some of the completeness of the answers, students are completeless in writing the size of a sketch, students have not conveyed mathematical ideas using complete sentences, and students have not been able to make logical arguments to support students' answers.Keywords: Mathematical communication, reflective cognitive style, open-ended

Abstract

Metacognition is one important component in cognitive function and cognitive development that has a close relationship with students' problem solving abilities. One factor that can affect student metacognition but is rarely considered in mathematics learning is student cognitive style. The purpose of this study is to describe the metacognition of field-independent cognitive style students in solving mathematical problems based on Polya's stages. This research is a descriptive qualitative study using a problem solving test instrument and interview guidelines to collect data. The subjects in this study were 2 field-independent cognitive style students. The subject was asked to work on mathematical problem solving problems and then interviewed based on the results of student work. The results showed that students' metacognition awareness, regulation, and evaluation emerged during the problem solving stage. This shows that metacognition can help students with field-independent cognitive style in solving problems.
