  • Mathematical Communication ability can be more developed through sharing thoughts with others. Therefore when we instruct students in math, it is very important for teachers to provide them with opportunity to communicate mathematically. So this study provided open-ended problems in small-group collaborative learning. And we analyzed students' mathematical communication focused on the student's level of understanding. Furthermore, to improve students' mathematical communication ability, this study tries to attract the factors that we should consider the exact date for inserting the open-ended problems into a course of math and the student's level of understanding for selecting suitable open-ended problems.

  • Goos(2004) introduced educational researchers' demand for change on the way that mathematics is taught in schools and the series of curriculum documents produced by the National council of Teachers of Mathematics. The documents have placed emphasis on the processes of problem solving, reasoning, and communication. In Korea, the national curriculum documents have also placed increased emphasis on mathematical activities such as reasoning and communication(1997, 2007).The purpose of this study is to analyze the impact of inquiry-oriented instruction with guided reinvention on students' mathematical activities containing communication and reasoning for science high school students. In this paper, we introduce an inquiry-oriented instruction containing Polya's plausible reasoning, Freudenthal's guided reinvention, Forman's sociocultural approach of learning, and Vygotsky's zone of proximal development. We analyze the impact of mathematical findings from inquiry-oriented instruction on students' mathematical activities containing communication and reasoning.

  • This study has investigated the way to improve the communication skills emphasized in mathematics education, and analyzed the effects of Communication Oriented Mathematics Lessons on the mathematical disposition and the academic achievements. For this research, two groups of first grade students from D elementary school in Daegu city were selected which had been proved homogeneous in mathematical disposition and academic achievements via a preliminary test. The experimental group was given Communication Oriented Mathematics Lessons (COML) while the control group was given Traditional Classroom-based Instruction (TCI). COML were given along with first grade, first level mathematics for eight weeks, to improve communication skills of the students who were unfamiliar with mathematical communications. The schemes for the education include revising, summarizing, asking questions, and participating. The results of the study were summarized for mathematical disposition and academic achievements. First, COML is effective to evaluate the will to solve problems in the mathematical disposition of the students, and to make it useful for them to live their lives and to learn other subjects. Second, previous studies have shown contrary interpretations on the effects of COML. This study has found that it does not improve the students' scores on the original form of academic achievement test.

  • This study was proposed to analyze mathematical communication activity and mathematical attitudes while students were solving project problem and to consider how the conclusions effects mathematics education. This study analyzed through qualitative research method. The questions for this study are following, First, how does the process of the mathematical communication activity proceed during solving project problem in a small group? Second, what reactions can be shown on mathematical attitudes during solving project problem in a small group? Four project problems sampled from pilot study in order to examine these questions were applied on two small groups consisting of four 5th grade students. It was recorded while each group was finding out the solution of the given problems. Afterward, consequences were analyzed according to each question after all contents were noted. Consequently, conclusions can be derived as follows. First, it was shown that each student used different elements of contents in mathematical communication activity. Second, during mathematical communication activity, most students preferred common languages to mathematical ones. Third, it was found that each student has their own mathematical attitude. Fourth, Students were more interested in the game project problem and the practical using project problem than others.

  • Mathematical communication has been emphasized not only as the process of learning mathematics but also as the objective of mathematics education. However, little studies have been conducted with regard to what to consider and how to implement in the actual classroom for promoting mathematical communication. Given this background, this paper implemented a mathematics instruction in each of 2nd, 4th, and 6th grade classrooms in which specific learning objectives were considered to promote discourse-based mathematical communication. It then analyzed the degree by which such learning objectives were achieved and the linguistic interactions between the teacher and students in each classroom. This paper finally provided issues and suggestions for effective discourse-based instruction in mathematics classroom by analyzing similarities and differences among the three classrooms.

  • The purpose of this study was to provide useful information for teachers by analyzing mathematical communication emphasized through 'exploratory activity' and 'story corner' in elementary textbooks based on the revised curriculum. Two classrooms from the first grade and second grade respectively were observed and videotaped. Mathematical communication of each classroom was analyzed in terms of questioning, explaining, and the sources of mathematical ideas. The results showed that only one classroom focused on students' thinking processes and explored their ideas, whereas the other classrooms focused mainly on finding answer. Particularly, this tendency often appeared when implementing 'story corner' than 'exploratory activity'. The reason for this was inferred that teachers were not familiar with teaching mathematics in stories and that teachers' manual did not include concrete questions and students' expected responses. This paper included implications on how to promote mathematical communication specifically in lower grades in elementary school.

  • The purpose of this study is to set appropriate targets for school-year levels and types of mathematical communication. First, I classify mathematical communication into four types as Discourse, Representation, Operation and Complex and refer to them collectively as the 'D.R.O.C pattern'. I have listed achievement factors based on the D.R.O.C pattern hearing opinions from specialists to set a target, then set a final target after a 2nd survey with specialists and teachers. I have set targets for mathematical communication in elementary schools suitable to its status and students' levels in our country. In NCTM(2000), standards of communication were presented only from kindergarten to 12th grade students, and, for four separate grade bands(prekindergarten through grade 2, grades 3-5, grades 6-8, grades 9-12), they presented characteristics of the same age group through analysis of classes where communication was active and the stated roles of teachers were suitable to the characteristics of each school year. In this study, in order to make the findings accessible to teachers in the field, I have classified types into Discourse, Representation, Operation and Complex (D.R.O.C Pattern) according to method of delivery, and presented achievement factors in detail for low, middle and high grades within each type. Though it may be premature to set firm targets and achievement factors for each school year group, we hope to raise the possibility of applying them in the field by presenting targets and achievement factors in detail for mathematical communication.

  • The purpose of this study is to examine the effects of mathematics instruction using children's literature on students' mathematical communication and attitude. To conduct this research, a total of 59 6th grade students were selected from an elementary school in Seoul, and three different types of teaching methods using children's literature were applied to the treatment group, while a traditional teaching method was adopted to the comparison group. Children's literature was used in the actual classroom environment for about 20 minutes in the course of 10 weeks treatment, and the results were analyzed to find the effects of using children's literature during mathematics teaching on students' mathematical communication skills and attitudes toward mathematics. The results of the present study were as follows: First, with respect to mathematical communication aspects, the treatment group achieved significantly higher mathematical communication skills than that of the comparison group. That is to say, this result shows that students learning mathematics using children's literature seem to have more mathematical communication abilities than students in the textbook-based mathematics learning group. Secondly, the results of this study point out that students in the treatment group have more positive attitude toward mathematics as a result of learning that the other group of students focused on textbook-based mathematics learning. In conclusion, the current study demonstrates that mathematics teaching using children's literature made more significant impact on students' mathematical communication ability and attitudes toward mathematics than the comparative method focused on a traditional textbook-based mathematics teaching method.

  • As the information society appears, the increasing power and access of personal computers along with wide spread use of the information technology has not only changed the landscape for communication but it has opened up new and exciting opportunities for education. One of the ways that information technology could help improve education is to be used in interactive communication to share the knowledge and experience of all the teachers as well as students. In this paper, the use and application of information communication technology[ICT] into mathematics classroom are described and showed several examples. furthermore, the web site design and developed for this study was introduced of the purpose of sharing the ideas about the knowledge and usage of the history of mathematics and examples of mathematical connections. The study suggests that enabling mathematics in incorporating of ICT by teachers and students requires more effort to be made in training teachers on the use and application of ICT into mathematics classroom.
