This research is a study on student's understanding fundamental concepts of mathematical curriculum, especially in geometry domain. The goal of researching is to analyze student's concepts about that domain and get the mathematical teaching methods. We developed various questions of descriptive assessment. Then we set up the term, procedure of research for the understanding student's knowledge of geometric figures. And we analyze the student's understanding extent through investigating questions of descriptive assessment. In this research, we concluded that most of students are having difficulty with defining the fundamental concepts of mathematics, especially in geometry. Almost all the students defined the fundamental conceptions of mathematics obscurely and sometimes even missed indispensable properties. And they can't distinguish between concept definition and concept image. Prior to this study, we couldn't identify this problem. Here are some suggestions. First, take time to reflect on your previous mathematics method. And then compile some well-selected questions of descriptive assessment that tell us more about student's understanding in geometric concepts.

Comparing to the other subject, hierarchy among mathematical contents is strong from the perspective of knowledge order as grades go up. That is, the knowledge that students already have learned, are learning and will learn are closed related from grade to grade. We expect students to be proactive and creative in studying mathematics, which is the goal of 21th century, analyzing their. knowledge structure based on the hierarchy of knowledge through assessment. Especially, using computer system we provide students with substantial feedback for the assessment as well as objective validity is increased along with speedy and exact process in a bid to help students' mathematical understanding grow. This paper seeks to analyze the assessment data by applying knowledge spaces to computer system and develops efficient methods based on the analyzed results, to diagram each student's knowledge structure.

2009 개정 교육과정에 따른 수학과 교육과정에서는 수학적 문제해결, 수학적 추론, 수학적 의사소통을 구성요소로 하는 수학적 과정 중심의 수학교육을 구현할 것을 강조하고 있다. 수학적 과정 중심의 수학교육이 성공적으로 이루어지려면, 학교에서 실시하는 학생 평가에 수학적 과정을 적절하게 반영하여야 한다. 본 연구에서는 교사들을 대상으로 하는 대규모 설문조사를 실시하여 수학적 과정 중심의 평가에 대한 수학과 교사들의 인식을 조사하였다. 설문조사를 통해, 수학과 평가 전반에 대한 인식, 정기고사와 수행평가에서 고려한 평가요소와 평가결과 활용 현황, 수학적 과정 구성요소 평가에 대한 인식 및 평가방법에 대한 의견을 확인하였다. 또한, 교사의 교직경력이나 소속한 학교의 학교급, 도시규모에 따라 교사들의 응답에 차이가 있는지 살펴 보았다. 연구결과를 바탕으로 수학과 평가와 수학적 과정 중심 평가와 관련한 시사점을 논의하였다.

이 연구는 영재를 위한 창의성 프로그램 개발과 적용 그리고 영재의 선발에 이용될 수 있는 문제설정에서의 수학적 창의성 평가에 대한 이론적 고찰과 관찰을 통해 개선된 창의성 평가 요인을 제안하기 위한 것이다. 이를 위해 대학부설과학영재교육원 소속의 초등수학영재 19명에게 주어진 문제를 풀어보고 그 문제와 관련된 우수한 문제를 만들도록 요구하였다. 영재학생뿐만 아니라 예비교사 및 전문가 집단이 각각 영재가 만든 문제를 평가하고 우수한 문제의 특징을 기술하도록 하였다. 이를 통해 문제설정에서의 수학 창의성 평가의 요인을 융통성, 독창성, 원 문제와의 유사성, 문제의 복잡성, 정교성으로 제안한다.

Producing tools for actively meeting social needs in a radical changing society due to the development of modern technology has been shifted from physical ability to intelligent ability. The prominence of educating creativity is perceived as a good preparation in order to deal with them. Considered that assessment which is systematic activity to collect, analyze, diagnose, and judge information of a series of instruction practices is means to impart evidence and feedback of teaching learning practices, education and assessment is placed on reciprocal relationship. Nevertheless, there has been some tendency of neglect of assessment, comparing education for upbringing creativity. In this paper model of pencil and paper problem is discussed focusing on the sub-components of creativity and problem solving as one of the variety of means to extend mathematical creativity.

The purpose of this study is to develop the assessment rubric of mathematical communication ability by each type: listening, speaking, reading, writing, and graphic. This rubric is qualified in the content-validity and reliability by professional educators' evaluation and correlation coefficient. 16 math educators judged that this involves the results of learning mathematical communication, the results of possible instruction, and the content of scoring mathematical communication by teachers. 170 middle school students were tested by the assessment task according to the types of mathematical communication. After two researchers and two teachers scored the tasks, correlation coefficient was calculated between evaluators. The coefficient is evaluated high in that it is more than 0.70.

수학적 창의성은 일반적 창의성에 기반을 두고 수학적 특성을 고려하여 연구되어야 하며, 그 평가방안에 대해서도 이러한 연구 방향과 일관되어야 할 것이다. 본고에서는 수학적 창의성을 인지적 측면에서의 수학적 창의력과 정의적 측면에서의 수학적 창의적 태도로 나누어 생각한다. 다음으로 두 측면에서의 평가에 관한 선행연구를 고찰하고, 지향해야 할 수학적 창의성의 평가방안을 모색한다.

The 2015 revised mathematics curriculum had newly introduced the term 'process-focused assessment'. The official document, however, did not offer an explicit definition of the new term, but only by virtue of narrative. This has encouraged practitioners and researchers to figure out themselves what it is and how it differs from those in use, formative assessment and performance assessment in particular, in use. In consequence, many versions of interpretation, all of which are not necessarily consistent, have been developed and implemented in schools, This, in turn, still has created a chaotic situation carrying out the process-focused assessment. This study attempted to make the meaning of the process-focused assessment more explicit by conducting a comprehensive review of the related literature, for implementing it in its intended way.

Despite the importance of learning to do mathematical proofs, researchers have reported that not only secondary school students but also undergraduate students have difficulties in learning proofs. In this study, we introduced a new toll for learning proofs and explored the reliability and the validity of peer assessment on proofs. In the course of a university in Seoul, students were given weekly proof assignments prior to class. After solving the proofs, each student had to assess other students' proofs. The inter-rater reliabilities of weekly peer assessment was higher than .9 over 90 percent of the observed cases. To examine the validity of peer assessment, we check whether students' assessments were similar to expert assessment. Analysis showed that the equivalence has been quite high throughout the semester and the validity was low in the middle of the semester but rose by the end of the semester. Based on these results, we believe instructors can consider the application of peer assessment on proving tasks as a tool to help students learn.

The purposes of this study are to develop the mathematical performance assessment tasks and to apply them to the middle school students. And I also intend to know the students' inclination and learning attitude to mathematics. In order to satisfy this study, I developed the performance assessment tasks and the standard program of marking about the mathematical function and statistics for the first grade students at middle school. After examining the students' basic investigation, their inclination and learning attitude to mathematics, I applied these developed tasks to them After that I put both classes and performance assessment into operation in all 15 periods. I set up two classes of the first grade students (49 students) at J middle school in Kongju, Chungcheongnam-do as a model group. The results of this study are as follows: First, owing to the developed performance assessment tasks of function and statistics, the teachers can operate the assessment system as a process of teaching and learning. Second, because of the application of mathematical performance assessment tasks, we can change the students' inclination and learning attitude to mathematics affirmatively. And by using these tasks, we can help the students to think mathematically. In this way, the students will be able to realize the real value of mathematics and have a growing interest in mathematics through all these meaningful processes. Judging from this study, we can elevate the students' abilities of problem solving and reasoning and improve teaching-learning method by applying the performance assessment tasks to them. Thanks to these tasks, the students will be changed affirmatively in their inclination and learning attitude to mathematics. I think that these tasks are very good assessment method which can call forth curiosity and interest. Besides, they can also help the students realize the real value of mathematics.
