  • 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.

  • This study investigated Korean fifteen-year-olds' (mis)conceptions on the greenhouse effect based on the PISA results. Based on previous studies on students' ideas about the greenhouse effect, Korean students'understanding of the natural factors and human-induced factors of the greenhouse effect were analyzed. Students' misconceptions about causes of the greenhouse effect were also examined. In addition to CO2, Students mentioned CFCs, atmospheric pollution, water vapor and methane as greenhouse gases. Many students indicated that the greenhouse effect and ozone depletion have a causal relationship. Teaching implications of the misconceptions were also discussed.

  • In this study, I hoped to reveal the understanding of pre-service elementary teachers about proportional reasoning and the traits of proportional reasoning strategy used by pre-service elementary teachers. The results of this study are as follows. Pre-service elementary teachers should deal with various proportional reasoning tasks and make a conscious effort to analyze proportional reasoning task and investigate various proportional reasoning strategies through teacher education program. It is necessary that pre-service elementary teachers supplement the lacking tasks such as qualitative reasoning and distinction between proportional situation and non-proportional situation. Finally, It is suggested to preform the future research on teachers' errors and mis-conceptions of proportional reasoning.

  • In this study, the simulation program using the randomwalk model is developed. Generally, students in the chemistry class have some difficulties to understand the motion of atomic particles or molecules. And then, they have many mis-conceptions about the motion of molecules. This program expressed by the computer simulations using the randomwalk theory may help students to understand visually the process of molecular motion. This program can be used easily, because it is based on Web by application of JAVA languages. The program consists of two parts. One is 'Diffusion' program, expressing the process of molecular diffusion as a computer simulation. Another is 'Randomwalk' program, expressing the trajectory of molecular motion to help the students to follow the random motion virtually.

The Effect of Science History Program Developed by Genetic Approach on Student's Conception toward Particulate Nature of Matter and Understanding about the Nature of Science (기원론적 접근법에 따라 개발한 과학사 프로그램이 학생들의 입자론적 물질관 및 과학의 본성에 대한 이해에 미치는 영향)

  • In this study, science history program was developed to enhance student's concepts toward the particulate nature of matter and the understanding about the nature of science. And the effects of its application was investigated in the lesson of ‘Composition of Matter' in middle school science class. This science history program was based on genetic approach and included the contents from the old Greek natural philosophers to Avogadro. Before instruction, the test of understanding about nature of science was administered, and the science scores of the previous course were obtained, which were used as covariates. During 24 class hours, this study was conducted with two classes(experimental and comparison group) in a middle school in Seoul. The experimental group was received lessons by science history programs and the comparison group was received traditional lessons. After instruction, the scientific concept test, the test of understanding about nature of science were administered. The result of this study indicates that the scientific concept scores of experimental group were significantly higher than comparison group at p <.01 level of significance. It means that the students in experimental group has more sound conceptions about the particulate nature of matter and less mis conceptions about matter than the students in comparison group. However, there was no significant difference between two groups in the score of understanding about the nature of science.

  • The purpose of this study is to investigate elementary school 6th grade children's preconception on body's digestion, circulation, breathing and excretion. By means of questionnaire, teacher is presented with misconception which students may have. On the basis of this way, firstly they draw up and put in free-concepts were investigated from objective test and sought after misconeption which student had and inquired whether the result of response made difference by sex and areas or not The result of study is as follows: 1. In the course of investigating and analyzing mis-preconecptios, teacher had misconceptions partially, as like students. 2. Many a student have misconceptions: nourishment in made for itself in body. 3. In circulation range most of students know that heart is making blood, and they don't make conception that blood is nourishment which was eaten from food. 4. They know the breath is only physiological function: they breathe to live. All air-breathing is necessary. 5. They are not relevant blood in course of urine and sweat formation they have non-scientific conceptions which water eaten is so. They know that all of sweat and urine and ordure is excretion. To sum up, many student have misconceptions as for digestion and circulation and breath and excretion of body especially. Circulation and excretion is more so. if inspection in a field of sex, they will know male had less misconceptions than female. in a field of region, student from rural are as had more misconceptions than the one from urban areas.

  • 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.
