수학교육의 궁극적인 목표 중의 하나인 문제해결력을 기르기 위해서는 그 기저가 되는 수학적 개념에 대한 이해가 뒷받침되어야 할 것이다. 본 연구는 영재교육 대상자들이 갖고 있는 수학 용어에 대한 오개념의 실태 및 형성 배경을 추정해 봄으로써 수학 오개념 예방 및 교수․학습 프로그램 개발과 지도에서 고려해야 할 정보를 제공하는 데 있다. 이를 위하여 이론적 측면에서 오개념의 의미 및 형성 배경을 살펴보았다. 그리고 오개념 실태를 알아보기 위해 대학부설 영재교육원생을 대상으로 수와 도형 영역의 수학 개념을 진술한 내용을 분석한 결과 수학적으로 올바르게 진술한 학생은 35%정도이며, 개념형성 수준을 4수준으로 나눌 경우 관점에 따라 예(例)와 비례(非例)의 구별할 수 있는 2수준과 개념의 공통적 속성을 인식하고, 자신의 표현으로 기술할 수 있는 3수준인 학생이 대부분이다. 그 배경을 추정해 보면 제한된 범례 제시, 잘못된 선개념, 개념 정의와 개념 이미지 사이의 불균형 등에서 찾을 수 있겠다. 이러한 추정을 바탕으로 수학적 용어에 대한 오개념을 해소 방안을 개괄적으로 정리하였다.

The understanding of mathematical concepts should be backed up on a constant basis in oder to grow problem-solving skills which is one of the ultimate goals of math education. The purpose of the study was to provide readers with the information which could be considered valuably for the math educators trying both to prevent mathematical misconceptions and to develop curricular program by estimating the actual conditions and developing backgrounds of the mathematical misconceptions held by the gifted education learners. Accordingly, this study, as the first step, theoretically examined the meaning and the developing background of mathematical misconception. As the second step, this study examined the actual conditions of mathematical misconceptions held by the participant students who were enrolled in the CTY(Center for Talented Youth) program run by a university. The results showed that the percentage of the correct statements made by participant students is only 35%. The results also showed that most of the participant students belonged either to the level 2 requiring students to distinguish examples from non-examples of the mathematical concepts or the level 3 requiring students to recognize and describe the common nature of the mathematical concepts with their own expressions based on the four-level of concept formulation. The causes could be traced to the presentation of limited example, wrong preconcept, the imbalance of conceptual definition and conceptual image. Based on the estimation, this study summarized a general plan preventing the mathematical misconceptions in a math classroom.

Typical misconceptions on Enterprise Resource Planning (ERP) among practitioners and researchers are reviewed. Companies can make, buy, or rent ERP solutions, but typically, ERP is conceived as ready-made, off the shelf application software package. The benefits of ERP adoption are frequently generalized without proper clarification of the requisite conditions. The specific outcomes of ERP adoption are not adequately differentiated from those of general computerization. To avoid the side-effects caused by those misconceptions, we 1) clarify the concept of ERP and the methods of sourcing it, 2) specify the requisite conditions for the benefits from packaged ERP solutions, and 3) explain the generic characteristics of ERP, direct effects and resultant possible outcomes of the adoption of ERP.
