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.

관광 목적으로 메타버스를 체험하려는 사용자는 문화콘텐츠의 목적에 의해 공간 속 전략적인 기획에 노출된다. 또한, 가상환경에 따라 진행되는 과정에서 통합적인 문화콘텐츠를 학습하게 되고 나아가 시공간적 의미와 함께 결국 스페이스텔링까지 경험하게 된다. 사용자에게 체험 시작부터 흥미를 유도하여 체험을 지속하는 것이 중요하지만 이러한 과정에서 장애요소들이 발생한다. 충분한 사전지식 없이 관심키워드만을 가진 사용자에게 새로운 정보와의 연결을 촉진 시켜야하기 때문이다. 따라서 흥미 제고를 위한 효율적인 설계 방법을 사전에 연구해야 한다. 그러나 현재까지 가상공간 속에서 흥미유발을 위한 선행조직자를 체계적으로 설계하는 방식에 대한 연구가 전무한 실태이다. 본 연구는 개발자가 가상공간의 의미와 문화콘텐츠의 스토리텔링을 개발하는 과정에서 발생하는 흥미유발 설계 방법으로 개념지도 기반 선행조직자 교육학습 기법을 이용한 기초 연구라고 볼 수 있다. 먼저 가상공간 요소와 인간행동 이론들을 고찰하였다. 이어서 현재 활용되어지는 선행조직자의 5가지 대표 사례들을 탐구하고 정보접근 및 전달 목적의 개념지도를 기반으로 재설계하여 제안하였다. 본 연구과정을 통해 메타버스 체험자들에게 공간적 속성과 인지적 흥미 요소가 스토리텔링 학습으로 이어지는 유의미한 학습에 효과적으로 전달되는 점과 개념지도를 통한 서비스 디자인 설계방법의 요소들을 확인할 수 있었다.

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.

본 연구는 2009 개정 기술 가정 교과서 의생활 영역 '친환경적 의생활과 옷 고쳐입기' 단원에서의 지식을 구조화할 수 있는 시각적인 수업전략으로서 개념도 개발에 목적을 두었다. 이러한 목적에 부합하도록 준거설정, 내용분석, 개념추출, 개념도 개발의 과정으로 진행되었으며 내용분석을 위한 분석대상은 2009 개정 기술 가정 교과서 10종이며 개념도 개발은 Cmap Tools V 6.02를 사용하였다. 본 연구의 분석과정과 결과는 첫째, 준거설정 과정에서 분석준거는 2007 개정과 2009 개정 교육과정 성취기준을 기준으로 설정하였다. 둘째, 내용분석 및 개념추출 과정에서는 교과서 분석을 통해 중단원 수준의 학습내용과 목표를 '의복선택과 구입', '의복손질과 관리', '의복수선과 재활용'의 세 가지 범주로 파악하고 일반적이고 포괄적인 중심 개념을 기준으로 세분화하여 개념을 추출하였다. 셋째, 개념도 개발과정은 추출된 개념을 바탕으로 개발되었으며 재검토 과정을 거쳐 수정 보완하였으며 총 10개의 개념도를 개발하였다. 개념도 구성은 '의복선택과 구입'에서 '의복마련계획', '의복구입시 고려해야할 점', '품질표시'의 사이즈, 취급시 주의사항, '의복 손질과 관리'에서 '세탁물 분류하기', '얼룩빼기', '물세탁하기', '의복수선과 재활용'에서 '의복 수선하기', '옷 고쳐입기', '친환경적의생활'로 구성되었다.
