This article studies the understanding of acid and base concepts of the 3rd-grade students in middle school. An effective teaching strategy for improving their acid and base concepts was designed by considering students' prior knowledge using Lawson's learning cycle method. The control group was adapted by the traditional teaching strategy which isn't considering students' prior knowledge. After the class, understanding of acid and base concepts of treatment group was significantly higher than that of control group. But the level of students' understanding of strong acid, weak acid strong base and the strength of acid in aqueous solution was low even after the class of two groups. This indicates indirectly that the microscopic views of acid and base concepts in aqueous solution are not easy to learn for these students. For the four categories of acid and base concepts, students' responses were reviewed carefully and classified into scientific conceptions and misconceptions. These results will be useful for developing an effective teaching strategy of acid and base concepts.

The purpose of this study was to validate the Korean version of Inventory of Parent Attachment(K-IPA), The first version of K-IPA was developed through the process of translation and tack translation of items of parent attachment from Inventory of Parent and Peer Attachment (Armsden & Greenberg, 1986), content validation test with 30 elementary school children, and content validation test with an expert group. The validation test with 964 students (emementary, middle, high school) confirmed all 25 items(each items were asked for mother and father) were appropriate and reliable, K-IPA consists of three different sub-scales, 10 items for trust scale, 9 items for communication scale, and 6 items isolation across all age groups.

Ministry of Education has proposed storytelling in context of the actual or fantasy for the sake of fun and easy mathematics education. However most of school mathematics is not associated with the real life. In that case it could be one method for cultivating positive affects about mathematics that we make up and apply mathematics narrative with which we can reveal what makes mathematics interesting. In this study, among every problem in every examination in four regular examination that targeted the first-year of one ordinary high school in Seoul, I elected a total of four problems, and wrote a total 4 of mathematics narratives. I analysed a case on a few students with which I had conversations after teaching those 4 number of mathematics narratives, and studied mathematics narrative's influences on affects about mathematics of ordinary high school students. As a result, from one of a few students we could observe that his mathematical emotional mind had varied positively. From the student and the other students who had been engaged I discussed some implications and some points to be improved about making up and applying mathematics narrative for cultivating positive affects about mathematics.

To develop and test validity and reliability of Korean version of the Student Perception of Patient Safety Knowledge, Skills, Attitudes to assess applicability for nursing students. Survey data were collected from convenience sample of 425 fourth year nursing students who enrolled in four universities. Data were evaluated using item analysis, content validity, exploratory factor analysis, and Cronbach's alpha. The attitudes scale was eliminated since item-total correlations were less than .3, on the final Korean Version Scales. The attitudes subscale needs further refinement before implementation. The finding out this study demonstrate that the knowledge and skills scales showed satisfactory validity and reliability. It is useful to evaluate nursing students during educational preparation and in practice.

This study examined the curriculum CQI forms implemented at A university for quality management and improvement of instruction. Under the reorganization of competency-based curriculum, University A has improved the CQI form so that the planning, process and outcomes of class can be managed systematically. This study proposes a CQI form through literature research and has undergone a revision process through external expert verification. The major findings are as follows. First, when developing the CQI form, the questions were composed to evaluate and reflux the entire course of the class, including the planning, operation, results, and feedback of the class. Second, it was divided into three stages such as last semester, current semester, and next semester to prepare a comprehensive analysis and improvement plan, so that the effect of continuous class improvement and reflux can be obtained. Third, integrating the lesson plans and lecture evaluation results in the preparation of CQI increased the convenience of instructors. Fourth, the objective results (achievement results for each evaluation tool, lecture evaluation results) were provided to the instructor so that they could sufficiently reflect on them. This study is significant in that it provides implications for future CQI development.

The purpose of this study was to develop, field test an instrument to assess secondary school students' conceptions of the nature of science. The instrument named Philosophical Perspectives Probe(PPP) is a pool of 24 multiple-choice items that address a wide range of philosophical topics of science. The statements and the choices of this instrument were derived from an analysis of various philosophical positions. The main philosophical systems of the instrument are inductivism, falsificationism, and relativism, respectively. Major distinctions depend on the issues of the criteria of demarcation, patterns of scienctific change, epistemological status of scientific knowledge, and the scientific methods. The researchers also offer teachers a new way of assessing and interpreting their students' conceptions on a wide variety of topics related to the nature of science.

The Government has established the infrastructure for knowledge and information-oriented society, strengthening the ICT technology education. Although information knowledge ability of learners is prerequisite to educate ICT, but systematic educating courses and time for that are insufficient, and many difficulties have been pointed out. In order to solve such problems, this study developed Web-based computerized adaptive testing system using the item response theory. This system enables the learners to evaluate their own ICT knowledge abilities in their school or home by using familiar web interface and to perform supplementary or deepening study according to the results, and consequently, smooth education of ICT application will be achieved. In addition, this system will be a very effective method for the elementary/middle/high-school ICT knowledge ability certification system.

The methods developed to measure visual fatigue so far are quite few and lack of validity, and more importantly, they do not figure out the complex properties of the visual fatigue. The purpose of the research was to analyze the factors comprising the visual fatigue and to develop the method to measure it validly. The results are summarized as follows. First, we found that the 3D visual fatigue was comprised of four independent factors (visual stress, eye pain, body pain and image blurring factors). Second, we developed 29 items that measure four factors of 3D visual fatigue. Finally, the watching duration and binocular disparities affected the visual fatigue as had been expected. These results imply that the developed method does measure the three dimensional fatigue validly.

The paper is aimed to develop coaching competency model for executives and analyze their needs. For better outcome, we take coaching experts and executives and managers with business coaching experience as the target and conduct Delphi survey three times. According to the 3 surveys, we derived 5 coaching competency clusters and 34 individual competency items. The next thing, we have designed 102 survey questions which measure the 43 competency items and verified the validity for 272 respondents composed of managers and executives participated. As a result, the Analysis is secured with the validity at the 26 competency items. To investigate the competency that is important to executives, we carry needs analysis into execution. Borich's needs to utilize executive coaching competencies results conducted on 5 priority groups that belong to the competence of the 26 sub-competencies have business acumen the needs of high-capacity was analyzed. followed by motivation inspiring, organizational management, conflict management, strategic thinking and negotiation skills.
