A Study on the Mathematical Communication and Problem Solving Using Internet in Pattern

인터넷을 활용한 패턴 학습에서의 수학적 의사소통 및 문제해결에 관한 연구

Internet was introduced to this study for making mathematics class the surroundings where students can solve the mathematics problems and communicate mathematically in a free way without restriction of time and place. With the intention of investigating mathematical communication and problem solving in mathematics education using internet, the objects of this study were determined as follows: First, how does a student express mathematical idea in problem solving using internet\ulcorner Second, is there any difference in the degree of participation of mathematical communication according to schoolwork accomplishment and characteristics of the student\ulcorner Third, what's the effect of class using internet on problem solving of mathematics class\ulcorner A case study was executed for the solution and the subjects were all students(44 persons) of a class in the fourth grade of elementary school in D city got into web-site of internet and had class with it and 8 students out of them were deeply analyzed. Their results were shown on internet, and eight of them had interview for deep research after survey with questionnaires for all of the students after class. The results and the conclusions of this study were as follows: First, it showed that there was various types(simple statement, fact enumerating, logical thinking, using letters and formula, insufficiency of explanation) of the mathematical idea expression in internet according to students and study using internet seems to be helpful to the improvement of logical his own expression through other students' expression. Second, it showed that there was difference in mathematical communication participation according to the student's characteristics and it helped students of poor schoolwork be interested and confident in mathematics. Third, it showed that pattern study using internet had effect on forming a habit of reason and verification in problem solving in mathematics class. Accordingly, pattern study using internet seems to have a positive effect on increasing mathematical interests and solving problems in mathematics class.

본 연구는 수학 교실에서의 시·공간적 제약에서 벗어나 자유롭게 수학 문제를 해결하고 다양한 수학적 의사소통을 할 수 있는 환경을 조성하기 위하여 인터넷을 도입하였다. 인터넷을 활용한 수학 교육에서 나타나는 수학적 의사소통과 문제해결의 형태를 알아보았다. 본 연구를 통하여 인터넷 환경에서 수학적 아이디어를 표현하는 방법은 학생들마다 다양한 유형으로 나타났으며, 인터넷을 활용한 학습은 다른 학생들의 표현 방법을 통해 자신의 표현 방법을 보다 논리적으로 개선하는 데 도움을 줄 수 있는 것으로 보여진다. 학습자의 특성에 따라 수학적 의사소통 참여 도에 차이가 있었으며, 학업성취도가 낮은 학생들에게는 수학에 대한 흥미와 자신감을 갖게 하는데 도움이 되었다. 또한 인터넷을 활용한 패턴 학습이 수학 교실의 문제해결에 있어서 이유 및 검증의 습관화와 과제 집착력 증가에 영향을 미쳤다.
