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

This research involves 38 JUNIOR students with math skills vary, 12 students with high math ability, 18 students with the capabilities of the math medium, and 8 students with a mathematical ability is low. The entire students are asked to work on the problem-solving tests individually, with its main focus are as follows: (1) students were asked to write down what was known to be reserved; (2) write back what is asked the question; (3) write the problem resolution plan; (4) to resolve the issue in accordance with the plans that have been written; (5) try the other possible alternative in resolving problems; (6) rechecking problem resolution. The findings show that students answer math problems solving has diversity which is categorized into four categories: no changes mean, a variability of blind, orthodoxy, and creativity. Students in the creative categories are students who can solve problems by integrating CT and DT by using two models: the CDM and DCM. Students in this category can have opportunities to create and explore the variability.

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

This study was initially based on the researcher?s interest in a case found in students as they responded mathematical problems provided in the form of critiques to a problem. The study aimed to explore the students? arguments to describe the students? thinking processes while they are giving critiques to a mathematical problem. The study was qualitative research in a case study involving one student as a subject of research.  The finding showed that the students used 4 series of arguments as the main reason to give critiques to the given problem. The critiques were delivered due to several factors consisting of; (1) the students? inability to discover appropriate strategies to deal with the given problems; (2) the personal experiences kept in a Long Term Memory, and (3) the fallacy on reasoning.

Abstract

During this time students failed to understand the broad concept of the area because they did not have an intuitive understanding structured beforehand in early grade elementary school students. The research focuses on the strategies and intuitive development of students in measuring the area in 20 third grade students of elementary school. The research method used is descriptive qualitative. Students are given 3 assignments in different times and selected subjects based on different characteristics that appear each one for interviews. The findings of this research are 2 visual-concrete covering strategies and measurement estimation. As well as 6 levels of development of intuitive understanding namely level 0: incomplete covering, level 1: primitive covering, level 2: visual-concrete covering, level 3: covering array constructed from unit, level 4: covering constructed by measurement estimation, level 5: array Constructed constructed by measurement, level 6: array implied, solution by calculation

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

The aim of this article is to identify the steps which were done by the students in solving Pythagoras? word problems. This study used qualitative research by using explorative descriptive approach. The subject of this study was four students who werein seventh grade of Junior High school of Muhammadiyah 1 Jember.  The subjects givenone problem in the form of story that had to be done based on their styles.  From the result analysis of the study was found that the students tried to understand the aim of the problems by using picture, compass direction, and Pythagoras? pattern. In solving Pythagoras? word problem, the students used representation of schematic visual. In making schematic picture, the students were supposedto be consistent with compass direction. The student that isconsistent with compass direction can make the schematic picture correctly and with a picture,the student can solve the word problems by using Pythagoras? pattern correctly. The student who is inconsistent with compass direction will get difficulties in making schematic picture and not be able to solve Pythagoras? word problems correctly.

Abstract

Imitating performance is not a mediocre element, yet it is a unique ability possessed by humans. Researche concerning on imitating performance has been widely conducted in early childhood education and in adults educations. However, imitating performance studies related to elementary school context is rarely explored. This study was intended to figure out the imitating performance of 5th grade student. This study was analyzed qualitatively where the researcher involved in all stage of the research. The results of the research indicated that there were few imitating performance indicators that were not fullfiled. The students were not able to apply the examples in the new context, in other words the students had failed in applying the examples. Consequently, they faced difficulties in communicating the solutions of mathematical problems.  Instead of helping the students, the key words provide by a teachers make the students confuse in resolving different problems.

Abstract

In this paper we report students? reversible reasoning types on function composition problem. Reversible reasoning can be observed according to operation and structural correlation among input, process, and result.  There are seven students participate in doing function composition related to structural correlation in (f?g)(x)=h(x), The researchers assume that there are four types of reversible reasoning in composition problem, namely: (1) reversible on composition; (2) reversible on function; (3) reversible on substitution; (4) reversible on variables. However, there are only two appearing reversible reasoning, they are: reversible on function and reversible on substitution. Each type were selected a subject to be interviewed for 25 minutes and asked to do the Function Composition Task (FCT). Subject with reversible on function type identifies structural correlation among input, source and result as well as involving inverse in input with permissibility (f(y)) to produce basic function (f(x)). Meanwhile, subject with reversible on substitution type, constructs result based on the input, identifies structural similarity and generalizes from the structural similarity to produce basic function.
