  • The purpose of this study was to investigate the computer-naive children's preconceptions of computer concept, anxieties for computer, the changes in preconceptions and anxieties by computer literacy teaching, and the effect of CASI(Computer Assisted Science Instruction) on the science achievement. For this study, 42 5th graders were sampled. They were divided into two groups, experimental group(male:10, female:11) and control group(male:12, female:9). Each group was randomly assigned in the elementary school. Preconceptions about computer were examined by individual interview. Computer anxiety score was measured by questionaires. The questionaires developed in this study consisted of total 21 items measured by Chronbach ${\alpha}$ (0.93) and Total Item Correlationtp(p=0.01, r = $0.40{\sim}0.72$). Computer literacy curriculum based on children's preconceptions was developed and then was treated for experimental group as a computer literacy course. Preconceptions of computer, computer anxiety, and CASI achievements were compared between experimental group and control group in pre and post test. The results of this study are as follows; 1) children's preconceptions of computer showed various non-scientific concepts as animism and obvious visiual thinking. 2) children's misconceptions and anxieties about computer did not show significant differences in terms of learning experience of computer. 3) computer literacy had an effect on eliminating children's misconception about computer. 4) computer literacy had an effect on diminishing children's computer anxiety. 5) children's misconceptions and anxieties about computer showed significant inter-correlation. 6) children's misconceptions and anxieties about computer were appeared negative effect on CASI achievements. As the results, children's misconception and anxieties about computer had an effect on CASI acheivements. Therefore before performing CASI, more systematic computer literacy might be taught in formal education.

  • Recently, self-efficacy is one of the critical constructs that have been found to influence human decisions about behavior selection and the performance associated with the selected behavior. The construct has been widely adopted and tested In the fields of social psychology and/or other behavioral sciences. In information systems field, however, it has been hardly studied, although computer self-efficacy could have been an important factor explaining and predicting human computer usage behaviors. From this perspective, main purposes of the study is to understand causal relation among the factors influencing computer self- efficacy, computer usage behavior and computer self-efficacy. The research reported in this study have several objectives; 1) to develop a measure of computer self-efficacy, 2) to Identify the factors influencing self-efficacy, and 3) to reveal the relationship between self-efficacy and computer usage behavior and then 4) to explain the causal model of computer self-efficacy. By reviewing the literature, past experience, others' use, encouragement by others, and anxiety are selected as the factors influencing computer self-efficacy. Four hypotheses concerning the relationship between each of the variables and computer self-efficacy are tested by LISREL. One more hypothesis about the relationship between computer self-efficacy and computer usage is also tested. The results show that computer self-efficacy is significantly influence by computer anxiety, encouragement by others, and computer experience, and that it is closely correlated with computer usage behavior.

  • As other major, students have difficulties to be successfully adapted to computer science major without some interest and skill to computer programming. In this paper, we try to find successful factors for computer science major freshmen students to computer programming. The factors we focused are programming experience before college entrance, taking liberal arts/natural science courses at high school, application motivations to computer major, existence of mentors, satisfaction to his/her computer department, student's holland job aptitude code. After analysis, taking liberal arts/natural science courses at high school, satisfaction to computer department, some holland job aptitude code are significant to their successful adaptation to computer major. Also, we found the holland job apptitude code is closely related to student's satisfaction to their major for engineering students including computer science students. Our analysis results will be a suggestion for designing computer science education program with students who enters college without some aptitude or preparation to his major.

  • The soaring increase in the number of Internet users combined with the constant computerization of business process has created new opportunities for computer criminals and terrorist. Fortunately, the computer security field is also progressing at a brisk rate. In particular, the field of computer forensics brings new ways of preserving and analyzing evidence related to computer crime. Computer forensics is a new emerging professions of the 21st century. It is the collection, preservation, analysis, and presentation of computer related evidence. For this reason, the various technology of computer forensics is regarded as a powerful tool for suppressing computer crime. Our aims is to introduce the overview of computer forensics technology. We also present the survey results of the state of the art of computer forensics in the domestics and of foreign country.

  • All technology has both intended and unintended effects, we have said, and information technology is no exception. Information technology offers a number of challenges: those of computer education, computer literacy, the ethical and societal impacts of computing and communication systems. Current computer education focuses primarily on the history, parts and usage of a computer, and programming, it does not fully include the moral standards or ethics that help guide behavior and conduct for citizens of Information society. The purpose of this study is to review of the theoretical issues and societal impacts of computers, communication systems and computer ethics; then, to nalyse current curriculum and content of school computer education in Korea: finally, to develop a possible course in computer ethics containing a goal statement and aspects of computer literacy. Contents in computer ethics covers issues of nettiquette, privacy, health, copyright-related software and network piracy, computer crime and viruses. Six suggestions are made for the computer ethics of Information Age in the conclusion.

  • Recently SW education has been emphasized in Korea, but many students do not have many opportunities to learn computer science. In this paper, I organized a computer science show to enhance interest and understanding of computer science. The computer science show consisted of understanding binary systems, send a text message, parity bit magic, finding a number card, and collecting colors (orange games). I applied the computer science show to elementary school students and looked at the results. Most of the students who participated in computer science shows did not have an "participation experience of computer science shows". As result of surveys, many students answered "I am interesting about computer science shows," "I am interested in computer science," and "I would recommend it to my friends nearby." Through research, I learned that computer science shows are a way for elementary students to draw interest in computer science and to create curiosity and interest in computer science. I found from research that computer science shows are a way to reduce students' learning burdens and to increase interest in computer science.

  • We must know computer terms to use, learn, and understand efficiently. It is important for the elementary school students who learn computer for the first time to understand computer terms correctly. This study investigates a computer terms in the elementary school computer textbook which have been used currently at the elementary school, selects suitable computer terms for the elementary school student, analyzes and classifies them as a 1 2th grade, a 3 4th grade, 5 6th grade by the elementary school computer curriculum, and also classifies those as information ethics, computer basic, application software, computer communication by the category. The expectations of this study are as follows. First, the result of this offers teacher to a computer terms guidance for usability which is essential to elementary school's computer class. Second, this can be used as a reference in making a elementary computer textbook or studying and training textbook for teachers. Third, this offers teachers to an important criteria when they select a computer textbook for elementary student in elementary school.
