The purpose of this study was to investigate why advance organizers (AO) are effective in promoting comprehension and mental model formation in terms of cognitive load. Two experimental groups: a concept-map AO group and a key-word AO group and one control group were used. This study considered cognitive load in view of Baddeley's working memory model: central executive (CE), phonological loop (PL), and visuo-spatial sketch pad (VSSP). The present experiment directly examined cognitive load using dual task methodology. The results were as follows: central executive (CE) suppression task achievement for the concept map AO group was higher than the key word AO group and control group. Comprehension and mental model construction for the concept map AO group were higher than the other groups. These results indicated that the superiority of concept map AO owing to CE load decrement occurred with comprehension and mental model construction in learning. Thus, the available resources produced by CE load reduction may have been invested for comprehension and mental model construction of learning contents.

The main purpose of this research is to search the effect of different types of advance organizers in elementary science classes, to the students in acquiring scientific concepts and its retentions. In order to proceed with the research, We have chosen 93 students of three different classes of fifth graders, studying in M elementary school in U metropolitan city. We have randomly chosen two classes as an experimental group and one class as a comparative group. In the first experimental group (Group1), advance organizer was put in a form of a sentence., and the second experimental group (Group2), advance organizer was put in a form of a picture. For the comparative group, We have not put any advance organizer, and the method of class was proceeded as it was before. The result of this research are as follows. Firstly, the result of 'One-way analysis of variance' on scientific concept grade, right after the experiment on three groups, has shown a meaningful difference that, the shape of advance organizer does affect the acquisition of elementary school students' scientific concept. Secondly, even though Group1, who was given with a sentence as an advance organizer, got higher scientific concept scores after the experiment than that of comparative group, However, there was not a meaningful difference between Group1 and comparative group. Thirdly, Group2, who was given with a picture as an advance organizer, has shown a meaningful difference from comparative group. Judging from the facts above, utilizing an advance organizer of a picture in elementary science class, will be very affective on students' acquiring scientific concept.

Users who want to experience the metaverse for tourism are exposed to strategic planning in space for the purpose of cultural content. In addition, users learn integrated cultural content in the process of proceeding according to the virtual environment. and Along with the meaning of time and space, users will experience space-telling. It is important to induce interest from the beginning of the experience to continue the experience. However, obstacles arise in this process. This is because developers should promote connections with new information to users who do not have sufficient prior knowledge and only have keywords of interest. Therefore, efficient design methods to enhance interest should be studied in advance. But so far, there has been no research on how to systematically design prior organizers to induce interest in virtual space. This study is an interest-inducing design method that occurs in the process of developing the meaning of virtual space and storytelling of cultural content, and can be seen as a basic study using conceptual guidance-based prior organizer education and learning techniques. First, virtual space elements and human behavior theories were considered. Subsequently, five representative examples of previous organizers currently used were explored, and redesigned and proposed based on a conceptual map for information access and delivery purposes. Through this research process, it was possible to confirm that spatial attributes and cognitive interest elements were effectively transmitted to meaningful learning leading to storytelling learning and elements of service design design method through conceptual guidance.

This Study attempts to verify the effects of expository and inquiry instruction on learning attitude and academic achievement of health education in elementary school. For the accomplishment of the above purpose, specific problems were formulated as follows: The expository instruction is based on David Ausubel’s Advance Organizers and the inquiry instruction, Richard Suchman’s Inquiry Training in this study. To testify the above research problems, 247 students of six classes were randomly sampled from sixth graders of “Y” elementary school, located in Suwon city. One group was taught by expository instruction method and other group was taught by inquiry instruction method. The measurement tools used in this study were learning attitude test, pre-post academic achievement test, expository teaching-learning sheets and inquiry teaching-learning sheets. The experimental treatments had been lasted for eight weeks from June to October 1996. After the experimental treatments, to testify the effects of the experiment, the pre-test and post-test were administered and the results of the tests were compared by t-test. The conclusions were as follows; 1. There was a significant difference between expository and inquiry instruction(p〈.001). Inquiry instruction was more effective than expository instruction in changing learning attitude. 2. There was a significant difference between expository and inquiry instruction(p〈.001). expository instruction was more effective than Inquiry instruction in changing academic achievement. This study suggests that instructional method should be determined in accordance with the purpose of the lesson.

The purpose of this study is to develop a concept map in a visual instructional strategy so that meaningful learning can be done by structuring knowledge in the section of eco-friendly clothing life and reform clothes. For this purpose, ten textbooks for the 2009 revised were analyzed, and 10 sub-area were selected to develop the concept map. The development was done by using Cmap Tools V6.02 and the study process has progressed content analysis, concept extraction, and concept map development. The analysis process and results of this study are as follows. First, in the course of setting standards, the analytical standards were set for the 2007 revision and 2009 revision curriculum achievement standards. Second, in the process of content analysis and concept extracting, through the analysis of textbooks, 'clothing selection and purchase', 'clothing care and management' and 'clothing reuse and eco-friendly'. The concept was extracted by subdividing on the basis of general and comprehensive core concepts. Third, the development process of concept map was developed and revised based on the extracted concepts, and the concept map developed was the 'clothing purchase plan', 'points to consider when buying clothing' 'quality', 'handle with care', 'classify laundry', 'remove stain', 'water washing', 'repair clothing', 'reform clothing', 'eco-friendly clothing life'.
