  • Recently, most classrooms in Korea are fully equipped with multimedia environments such as a powerful pentium pc, a 43″large sized TV, and so on through the third renovation of classroom environments. However, there is not much software teachers can use directly in their teaching. Even with existing software such as GSP, and Mathematica, it turns out that it doesn####t fit well in a large number of students in classrooms and with all written in English. The study is to analyze the characteristics of problem-solving process and to develop a computer program which integrates the instruction of problem solving into a regular math program in areas of quadratic functions and ellipses. Problem Solving in this study included two sessions: 1) Learning of basic facts, concepts, and principles; 2) problem solving with problem contexts. In the former, the program was constructed based on the definitions of concepts so that students can explore, conjecture, and discover such mathematical ideas as basic facts, concepts, and principles. In the latter, the Polya#s 4 phases of problem-solving process contributed to designing of the program. In understanding of a problem, the program enhanced students#### understanding with multiple, dynamic representations of the problem using visualization. The strategies used in making a plan were collecting data, using pictures, inductive, and deductive reasoning, and creative reasoning to develop abstract thinking. In carrying out the plan, students can solve the problem according to their strategies they planned in the previous phase. In looking back, the program is very useful to provide students an opportunity to reflect problem-solving process, generalize their solution and create a new in-depth problem. This program was well matched with the dynamic and oscillation Polya#s problem-solving process. Moreover, students can facilitate their motivation to solve a problem with dynamic, multiple representations of the problem and become a powerful problem solve with confidence within an interactive computer environment. As a follow-up study, it is recommended to research the effect of the program in classrooms.

  • Today, computational thinking takes an important role in problem solving in software education. As a result, software education as liberal arts for non-CS major students is rapidly expanding. It is necessary to study the effects of computational thinking on software problem solving ability compared to traditional programming language education. In this paper, we propose an evaluation model for analyzing the effects of computational thinking on the overall software development process, and analyze how the problem solving process is different for learners who take computing thinking classes and programming language courses as liberal arts courses. As a result, students who learned computational thinking showed higher ability in problem analysis and design process.

  • 중학교 1학년 학생들의 일차방정식에 대한 풀이과정에 변화가 있는지를 알아보기 위하여 일차방정식을 학습한 후 1차 조사를 하고, 5개월이 지난 후에 2차 조사를 실시한 결과는 다음과 같다. 첫째, 1차 조사와 2차 조사 간의 정답 비율의 차이를 알아보기 위하여 McNemar검정을 실시한 결과, 유형A의 문항 x+4=9에서 $p=.035^a$, 문항 $x+\frac{1}{4}=\frac{2}{3}$에서 $p=.012^a$로 나타났으며, 유형B의 문항 x+3=8에서 $p=.012^a$, 문항 6(x+20)=20에서 $p=.035^a$으로 나타났다. 둘째, 1차 조사에서 문제 유형A와 유형B의 풀이과정을 올바르게 표현하지 못하였던 학생들 중에 2차 조사에서 올바르게 표현한 학생들이 있는 반면, 1차 조사에서 풀이과정을 올바르게 표현한 학생들 중에 2차 조사에서 오류를 범하는 학생들이 나타났다. 셋째, 모든 문항에 대하여 일차방식의 풀이과정을 올바르게 표현하는 학생들이 있는 반면, 몇 개 문항은 올바르게 표현하고 몇 개 문항은 그렇지 못한 학생들이 있었다. 결론적으로, 주어진 모든 문항에 대한 풀이 과정을 올바르게 표현하였더라도 또 다른 문항이 주어졌을 때 그 문항의 풀이과정에서 올바른 표현을 할 수 있다고 예견하기가 어렵다는 것이다. 논문에서 조사한 세 가지 유형(유형A, 유형B, 유형C)에 대한 학생들의 반응을 분석한 결과에 따르면, 이 세 가지 유형의 문제 풀이과정을 분석함으로써 어떤 학생이 일차방정식의 풀이과정을 올바르게 표현할 수 '있는지', '없는지'를 판단할 수 있다는 것이다.
