  • The purpose of this study is to explore evaluation criteria that pre-service elementary teachers employ as they evaluate and select models to explain electric circuits. Thirty junior students in a university of education have participated in the study as a part of the science education course in which they were enrolled. The lessons for the participants have been organized as a cyclic sequence of different modeling pedagogies including the expressive, experimental, and evaluative modeling. The pre-service teachers have been given five electric circuits in order and asked to create models and further develop them through peer discussion. Their modeling activities have been video- or audio-recorded, and the recordings and their transcripts have been analyzed using a framework of model evaluation criteria. It reveals that the types and frequencies of evaluation criteria used are different between situations of model development and model selection. While empirical and theoretical criteria have been used dominantly in both situations, more various criteria have been employed in the situation where the pre-service teachers selected one model among alternatives. Implications for science education and science education research have been suggested.

  • Even though the rate of infection of HIV is very low compared to other countries, data show a steady rise in HIV infection rates among young people in South Korea. A peer education program was provided to prevent the incidence of AIDS in young people. The program used peer leaders to provide AIDS related information and counseling for middle school students. Peer leaders received special training in AIDS related education and counseling to assist their friends. Peer leaders worked with their mends in one-to-one or small group settings. A pretest-posttest control design (six months after intervention) was used to evaluate the effects of the peer education program for prevention of AIDS. A post-intervention survey found that do you mean six months after the program or after six months of programs of peer program activities, the experimental groups(groups with peer educators) showed better knowledge, more positive attitudes, and less sexual activity when compared to control groups of non-participants(groups without peer educators). Peer leaders showed significant gains in knowledge about HIV transmission, more positive attitudes and self-efficacy not to engage in high-risk behaviors. Peer education was an effective tool for increasing knowledge, improving attitudes and self-efficacy, and encouraging appropriate behavior change.

  • Using a psychometric paradigm, risk perception of 30 hazards was investigated for three social groups-college students, experts of technologies, and employees of environmental organizations. The aim of this study was to examine psychological dimensions of risk perception, namely, to replicate the psychological dimensions - dread and knowledge -, which Slovic et al(1978; 1984; 1987) found and to forker explore discrepancies between societal groups. The results confirmed the same psychological dimensions Slovic et al have found. However, there are a number of significant differences in perceived risk such as perceived social benefits and other risk characteristics between three groups that suggest differences in ecological attitudes. The results were compared with those of Slovic et af and the nature of differences in risk perception among three groups were discussed.

  • Catalogers have been reporting the ways they use the Internet for several years, but as yet there has been little evaluation done to determine for which areas of cataloging the Internet is a valuable tool and for which areas it is not as useful. A survey was conducted in an effort to elicit this information. The responses indicated four areas in which catalogers use the Internet : searching the OPACs of other libraries, communicating with colleagues, accessing online cataloging documentation and publications, and authority work. Some catalogers also related processes for which they have found the Internet to not be efficient.

  • The present study aims at encouraging discussion on research paradigms as well as research methodologies of records and archives studies. Reviewing research paradigms, defined by Guba and Lincoln based on basic beliefs, leads to the suggestion that the discipline needs to reach to a certain degree of consensus on ontological, epistemological, and methodological premises in order to inform and guide future research. To make the argument, the present study reviews all research papers published in two major journals: the Korean Journal of Archival Studies and Journal of Korean Society of Archives and Records Management, from 2007 to 2016. It then identifies 80 research papers from positivistic research and reviews 32 papers, which collected data through surveys and experiments.

  • The capstone design classes in the College of Engineering are often team project-oriented, and teamwork skills are reported to positively impact problem-solving abilities. While team project courses have various advantages, they also come with challenges such as social loafing and issues related to free riders, which consistently hinder the positive effects of team project courses. To prevent these issues, there is a need to provide a clear evaluation-reward system for team members' contributions. In this study, we examined the reliability of peer evaluation scores for team members' contributions and reviewed methods to incorporate them into team project grades. The review results indicated that peer evaluation scores are deemed to have considerable reliability from a qualitative perspective. However, due to the relatively small team size in team project courses (3 to 6 members per team), using the arithmetic mean of peer evaluation scores is statistically challenging. As a complementary approach, this study proposes limiting the reflection ratio of peer evaluation scores and applying a more macroscopic processing method, not the arithmetic mean, to incorporate peer evaluation scores for team contributions into grades.

  • The purpose of this study was to develop a rubric for assessing students' scientific argumentation. Through the analysis of relevant literature related to argument in science education for developing rubric, the procedure in development and the category in assessment for rubric were elicited. According to the general procedure in developing rubric, the standard for evaluating the argumentation derived three categories such as a form, contents, and attitude. The form category was further segmented into sub-functions composition, claim, ground, and conclusion in the whole. The category for contents was segmented into sub-functions understanding, credibility, and inference. And the category for attitude was set to sub-functions participatory level and openness. The standard for evaluating sub-functions in each of the categories formed in this way was minutely suggested with five stages. The rubric, which was developed on the basis of literature, was inspected through a regular seminar in one expert in science education and fellow researchers. The rubric, which was developed in the early days, was again modified by being verified on problem and improvement matter after being entrusted to four experts in scientific education. And, the finally-completed rubric indicated to be high with 0.96 in the content validity index by being verified the validity by the four experts in science education. The developed rubric will lead to being able to increase the understanding about demonstration in students, and to being available for being utilized as the criteria for developing the argumentation process program and for evaluating the argumentation activity.

  • This study was done to compare the effects of learner-led and faculty-led fundamental nursing practice on skill performance, self-directed learning, problem-solving competency, and satisfaction. The learner-led practice was consisted of pre-class open lab and peer supervision. The faculty-led practice was consisted of faculty supervision for a student individually without pre-class open lab. The study was a pre-posttest, non-synchronized, quasi-experimental design between two groups. Data from 134 nursing students in either faculty-led (n=54) or learner-led fundamental nursing practice group (n=80) was collected using a checklist and self-reported questionnaire. Nursing skill performance score and class satisfaction of the learner-led group were significantly higher than those of the faculty-led group. This study showed that learner-led fundamental nursing practice consisting of pre-class open lab and peer supervision was an efficient practice method to improve students' skill performance and satisfaction maintaining their self-directed learning ability and problem-solving competency.

  • The Employment instability of current employees should be related to uncertainty of switching job for experienced ones. Therefore, the researcher would like to look into the influence which is taken by Job Insecurity after verifying Job Instability Recognition through employees and identification of the level into Trust in organization, In particular, for the employee who is working in a catering department and expected to be ranked highly among tourist companies concerning Job Instability Recognition. According to the result of a tentative theory that Job Insecurity will effect negatively to Trust, conversely, it does not give any considerable effects both Trust in colleague and company. It just turned out that the risky factor of their dismissal could come to a substantial consequence to Trust in Superior. In this regard, a study shows that there isn't any relation to Trust in colleague even though there Is the cause of being fired. In this sense, employees can assume that a work evaluation or relationship with their superior, who work together in the field, is related to the risky factor regarding their dismissal. In other words, it turned out that there was no difference between regular employee and non-regular employee in the matter of Job-Instability-Recognition.
