This study aims to develop a class procedure for the application of classrooms that value context and to conduct science classes using this procedure to examine the effects. Among various contexts related to scientific knowledge, the study develops a teaching procedure for designing classes that focus on the contexts of discovery and real life. After verifying the content validity of the context-based design and the program to which it was applied, a class was conducted, and the responses of the children were checked. The final draft of the lesson design completed after revision and supplementation is as follows: context-based design was presented in four stages, namely, presenting, exploring the context, adapting the context, and organizing (share and synthesizing; PEAS). The goal is to enable people to experience the overall flow of scientific knowledge instead of focusing on the acquisition of fragmentary knowledge by covering a wide range of topics from the social and historical contexts in which scientific knowledge was created to its use in real life. To aid in understanding the newly proposed class procedure and verifying its effectiveness, we developed a program by selecting the "My Fun Exploration," 2. Biology and Environment unit of the second semester of the fifth grade. The result indicated that the elementary science program that applied the context-centered design effectively improved the self-directed learning ability of students. In addition, the effect was especially notable in terms of intrinsic motivation. As the students experienced the contexts of discovery and real life related to scientific knowledge, they developed the desire to actively participate in science learning. As this becomes an essential condition for deriving active learning effects, a virtuous cycle in which meaningful learning can occur has been created. Based on the implications, developing programs that apply context-based design to various areas and contents will be possible.

Today there are many Web courseware systems for formative evaluation and feedback. Formative evaluation and feedback provided according to users' response in most Web courseware systems, however, are simple texts showing only whether correct or wrong, correct answers, relevant information, etc., far deviated from actual context. Thus such a system may weaken the corrective function of feedback and, as a result, reduce learners' understanding of contents and the possibility of learning transfer. In addition, according to the learning theory of constructivism, learning is influenced by the situation, in which it happens, and knowledge is learned and transferred differently depending on the context in which it is learned. In the background, this study designed and implemented a contextual error-correction feedback system that can provide feedback in a context closely related and similar to the relevant situation according to the response of learners when formative evaluation is carried out in Web courseware. In addition, it applied 'correction/correct-answer-providing feedback', 'relevant information providing feedback' and 'contextual error-correction feedback' to Web courseware for learning actual productivity S/W and verified if 'contextual error-correction feedback' is more effective than other two types of feedback for learners' academic achievement.

The purpose of this study was to look into whether this mathematising learning utilizing realistic context has an effect on the mathematical thinking. To solve the above problem, two 5th grade classes of D Elementary School in Seoul were selected for performing necessary experiments with one class designated as an experimental group and the other class as a comparative group. Throughout 17 times for six weeks, the comparative group was educated with general mathematics learning by mathematics and "mathematics practices," while the experimental group was taught mainly with mathematising learning using realistic context. As a result, to start with, in case of the experimental group that conducted the mathematising learning utilizing realistic coherence, in the analogical and developmental thoughts which are mathematical thoughts related to the methods of mathematics, in the thinking of expression and the one of basic character which are mathematical thoughts related to the contents of mathematics, and in the thinking of operation, the average points were improved more than the comparative group, also having statistically significant differences. The study suggested that it is necessary to conduct subsequent studies that can verify by expanding to each grade, sex and region, develop teaching methods suitably to the other content domains and purposes of figures, and demonstrate the effects. In addition to those, evaluation tools which can evaluate the mathematical thinking processes of children appropriately and in more diversified methods will have to be developed. Furthermore, in order to maximize mathematising for each group in each mathematising process, it would be necessary to make efforts for further developing realistic problem situations, works and work sheets, which are adequate to the characteristics of the upper and lower groups.

Citizens should be sensitive to the complex and controversial SSIs (Socioscientific Issues), be able to make a responsible decision with evidence and empathy, and furthermore take political action for the larger welfare. The premise of this research is that understanding the nature of science (NOS) takes an important role when students and adults participate in the discourse on SSIs because SSI reasoning requires individuals to examine information and counter-information with skepticism. We therefore designed SSI programs that were incorporated with NOS by adapting a contextualized-reflective approach. The leading research question was to what extent SSI contexts contributed to promoting students' understanding of NOS. A total of 71 11th grade students participated in this program. The school was located in an urban city near the capital city of Seoul, South Korea. We designed SSI programs to cover the issues of genetically modified organisms, climate change, and nuclear energy. Each issue required four to six class periods to complete. We conducted pre- and post-program tests using the revised VNOS-C, recorded group discussions or debates and collected student worksheets to observe the increase of student NOS understanding. As a result of this program, students showed moderate improvement in their understanding of NOS.

이 연구는 고등학교 지구과학 탐구활동에서 소그룹활동을 학생들의 대화를 중심으로 분석하고, 반성적 탐구활동이 교육과정별로 어떤 차이를 보이고 소그룹내의 상호작용특성에 따라 반성적 탐구양식의 차이가 어떠한지 알아보는 것이다. 그럼으로써 학생들이 어떤 반성적 탐구양식을 보이며 어떻게 발달시키는지에 관한 이해를 제공하고, 수업속의 맥락은 이러한 반성적 탐구학습을 증진시키고 억압하기위해서 어떻게 상호작용 하는지를 알아보고자 하였다. 이에 대한 연구문제로 소그룹을 이용한 탐구활동 수업과 반성적 탐구활동수업 중 반성적 에피소드의 차이가 있는가, 소그룹내의 그룹상호작용의 특징에 따른 반성적 탐구유형의 차이는 있는가를 설정하였다. 이를 위해 고등학교 1학년 2개 학급을 선정 기존의 우리나라 교육과정에 의거한 탐구활동수업 4차시, 반성적 탐구교육과정 수업 4차시를 각각 실시하고 수업을 녹화 전사해서 언어행동 분석틀과 반성적 탐구의 3가지 맥락을 통해 분석하였다. 연구 결과 두 교육과정 모두 도입에서 두 교육과정 모두 A-AD맥락의 반성적 탐구가 전형적으로 자주 나타나며, 반성적 탐구 교육과정수업에서는 AD-SR가 주로 나오는 것으로 보아 과제활동초기에 역할 분담과 과제 활동의 전략을 세우며, 전략을 세울 때 영역개념을 이용하는 것을 안수 있었다. 우리나라 교육과정 수업에서는 반성적 탐구진술이 간단하고 계획과정이 짧으며, 주로 과제 맥락 내에서 반성적 탐구를 하는 것으로 나타났다. 전개부분에서는 두 교육과정모두 DI-DP, DI-A맥락의 반성적 탐구가 나타나 자료 항목과 자료 패턴 그리고 인공물과 관련시키는 반성적 탐구가 공통적으로 나타나며 반성적 교육과정수업에서는 대체로 자료 맥락의 영역개념과 과제 맥락을 연결시키는 반성적 탐구가 잘 나타나고 있다. 반면 우리나라 교육과정에서 주로 과제 맥락 내에서 반성적 탐구가 나타났다. 정리단계에서는 반성적 교육과정 수업에서는 DC-DP가 주로 나타났으며 우리나라 교육과정수업에서는 DC-DP DP-AD맥락의 반성적 탐구가 나타났다. 정리활동에서 우리나라 교육과정은 반성적 교육과정보다 자료 맥락의 영역개념을 더 자주 이용하고 다양한 맥락의 반성적 탐구가 나오고 있으며, 이는 우리나라 교육과정의 학습지의 활동이나 문제는 학생들에게 익숙하고, 자료 패턴을 가지고 행동결정으로 연결짓는 활동이 명확히 제시되었기 때문이라고 판단된다. 두 그룹의 상호작용 특징에 따른 반성적 탐구의 성향의 차이는 도입단계에서 그룹의 특징과 상관없이 A-AD, AD-SR맥락의 반성적 탐구가 나왔으며 전개와 정리단계에서는 N그룹에서는 DP와 관련된 의미 있는 반성적 탐구가 나오는 반면 M그룹에서는 이러한 맥락의 반성적 탐구는 아주 드물게 나타나며, GN과 관련된 행동결정이 자주 보이고 있었다. 정리활동시 주로 하는 기록 활동에서 N그룹에서는 다양한 맥락에서 반성적 탐구를 하고 있는 것에 비해 비교 그룹에서는 서로 견제하고 확인하는 상호작용의 특징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다

This study investigated how cognitive style and training context influenced visual discrimination skill acquisition and transfer under time pressure. This experiment consisted of a screening session, a training session, and a transfer session using random polygon comparison tasks. Screening session was designed to separate participants according to their cognitive style (analytic or holistic). Training session was divided into difficult and easy conditions. In transfer session, participants compared polygon pairs in a novel task. The stimuli were presented for 1.5 seconds to examine the influence of time pressure. Through the all sessions, this experiment measured accuracy and response time. According to the results of this study, analytic group responded as quickly as holistic group in the beginning of training session because time pressure induced them to the holistic strategy. However, as training session progressed, their slopes of reaction time increased, suggesting that their own analytic style emerged. Holistic group showed flatter slopes than did analytic group for training session. Of interest is the slopes increased at the beginning of transfer session, suggesting that they developed analytic strategies in difficult training context. It is suggested individuals differently develop strategic processing skills depending on cognitive styles even under time pressure.

This study investigates the effectiveness of virtual reality agents as foreign language instructors with focus on the impact of different native language backgrounds and instructional roles. The agents were first distinguished as native or non-native speakers treated as a between-subject factor, and then assigned roles as either teachers or salespersons considered within-subject factors. An immersive virtual environment was developed for this experiment, and a 2×2 mixed factorial design was carried out. In an experimental group of 72 university students, statistically significant interactions were found in learning satisfaction, memory, and recall between the native/non-native status of the agents and their roles. With regard to learning confidence and presence, however, no statistically significant differences were observed in both interaction effects and main effects. Contextual learning in a virtual environment was found to enhance learning effectiveness and satisfaction, with the nativeness and the role of agents influencing learners' memory; thus highlighting the effectiveness of using virtual reality agents in foreign language learning. This suggests that varied approaches can have positive cognitive and emotional impacts on learners, thereby providing valuable theoretical and empirical implications.

The Web is evolving quantitatively into an explosive development. However, users usually have heavy burden of searching information because of the absence of contextual meaning on the Web. Due to an enormous amount of information, users have to endure for finding strong cohesive keywords by themselves and read each of the documents with enduring effort. This paper proposes an efficient method of searching more relative documents than current KEM-based searching systems on the Web by using contextual meaning. We designed a domain ontology on computer hardware, and a searching system which was searching those e-Learning objects. Owing to the Ontology-applied search system, information such as educational materials and related multimedia can be easily provided to the users. Further, learners could be informed of relationship of knowledge, e.g., class hierarchy, properties and values, and so on. The request results are semantically related to users' needs, and thus the system provides a learner-centered searching.

This study examined the effects of web-based learning experiences, learning style, and Internet self-efficacy that influence beginning child care teachers belief about web-based learning. The participants were 215 beginning child care teachers who work in child care centers. Data were analyzed by means of frequency analysis, correlation, and multiple regression for SPSS windows. The results were as follows: First, significant statistical differences were detected in web-based learning experiences and beliefs about web-based learning. Online teacher learning community use and frequency were significant gaps in beliefs about web-based learning. Second, there were statistical differences in learning styles and beliefs about web-based learning. And teachers with assimilator learning style showed high difficulty beliefs about web-based learning. Third, teachers' belief about web-based learning was significantly related to Internet self-efficacy. It means that teachers that have high Internet self-efficacy show high belief about web-based learning. Forth, among the teachers' personal variables, a higher level of online teacher learning community use and Internet self-efficacy predicted higher beliefs about web-based learning. Thus, this study suggested the importance of web-based learning experiences and Internet self-efficacy to beliefs about web-based learning. And it implicated ways to improve positive beliefs about web-based learning of beginning child care teachers.
