The purpose of this study is to investigate the effect of concept mapping strategies on the learner's achievement and their attitude change in science learning. The subject was 159 male students in a middle school in Seoul. Three experimental groups were instructed with different kinds of teaching methods about the unit of photosynthesis and digestive organs. Group I was instructed with traditional teaching method, GroupII was instructed with guided concept mapping strategy, GroupIII was instructed with student-centered concept mapping strategy. The major findings of this study are as follows. 1. Student-centered concept mapping strategy was observed effective at 0.05 significance level in achievement and retention. 2. Only student-centered concept mapping strategy changed students' attitude toward science learning positively. 3. It was observed that there was very significant correlation between the learning ability and science achievement (p<0.01). 4. Student-centered concept mapping strategy was found effective in upper learning-ability group, and guided concept mapping strategy in middle learning-ability group(p < 0.05). 5. Student-centered concept mapping strategy was effective to the groups of upper and middle learning-ability in changing students' attitude toward science learning(p < 0.05).

In this study, the researcher tried to find out the effect of using a computer interface in teaching speed concept in the elementary school. The 4th and 5th pupils were sampled for this study. The school is located in a sub-urban agricultural area in Korea. In the study, the subjects were divided into two groups: experimental and comparison group. From the pretest, two groups did not show any difference in the understanding of speed concept. The computer interface and the programs to operate the interface and data analysis were developed by researcher. The interface is a modular type and designed ready to connect to microcomputer. The test items were consisted of (1) comparison of speed, (2) change of motion, (3) acceleration, and (4) deceleration. As the result, the researcher found the following results: 1. In case of speed comparison, no significant difference was found between experimental and comparison group. 2. In case of change of motion, acceleration, and deceleration, the experimental groups showed higher achievement both in 4th grade and 5th grade. However, the 4th graders showed more learning than the 5th graders. In conclusion, this study showed that the use of computer interface seemed to be very effective in teaching and learning speed concept in elementary school.

This study aims to describe various teaching cases about 'earth revolution' in terms of PCK; knowledge of curriculum, knowledge of teaching strategies and knowledge of assessment. Based on these various cases we suggested PCK progressions about 'earth revolution'. For these, we recorded 'solar system and star' classes of nine elementary school teachers' in Kangwon, Gyeonggi, Gwangju, and Seoul. We adopted Lee & Lee (2016)'s topic-specific PCK framework to analyze the classes. As results, we suggested topic-specific PCK progression about 'earth revolution'. The results showed the upper anchor of the earth revolution class were exploring the reason of the change of constellation, finding the tendency of constellation change. These teachings were carried by the teachers' adaptive strategies. The upper anchor of the assessment was monitoring students' understanding during the whole class. The PCK progression about 'earth revolution' could help the teachers plan the earth revolution class, and reflect their own teachings.

Education is an intentional change of human behaviors. This change is implemented through the learning process of humans. The principles in the learning process and its psychological mechanism are based on learning theories. The objective insight about how they are related with school libraries as a basic organization supporting school education, what they can contribute and what their research methodologies are is a base for educational and academic research of school libraries. This study at first is to investigate learning and teaching theories for school libraries based on behavioral learning theories, cognitive learning theories and constructive learning theories which are general trends for learning theories. Then it is to introduce new theory 'library-based education approach (LBEA)'as an educational base of school libraries.

The purpose of this study was to investigate the effect of two teaching strategies, benefit appeal, on the nutrition knowledge, attitude toward nutrition and food behavior of 165 university students. We presented university students with either a treat appeal, which emphasized the risks of not-following the recommendations, or a benefit appeal, which emphasized what was to be gained if respondents followed recommendations. We assigned a random sample of 165 students either to a control group or to one of two experimental groups : a threat- or benefit-appeal group. Only respondents in the experimental groups received brochures, but all respondents completed pre- and post- test questionnaires. Students in the benefit appeal group demonstrated significant increases in both nutrition knowledge and more positive attitudes about nutrition education after participation. The control group, however, had no significant increase in knowledge at post-testing. Significant positive correlations resulted at post-testing between nutrition knowledge and attitude, as well as attitude and food behavior for the experimental group. Results from this study suggest that a change in nutrition knowledge precedes a change in attitude. The benefit appeal group appeared to be most effective in changing nutrition knowledge, attitude toward nutrition, and food behavior. (J Community Nutrition 2(2) : 159∼163, 2000)

Rethinking and re-conceptualization of knowledge organization has become necessary as a result of recent changes brought by digitization, networked resources, and interdisciplinary shifts. This paper calls for a review of curriculum and changes in teaching approaches to respond to these changes. The paper suggests expanding the scope of knowledge organization by adding new topics, and recommends placement of these topics in different courses (introductory or foundation courses, core or required courses, and electives or specialized courses) for a balanced approach. The paper also proposes a change in the mindset about the target of these courses and recommends knowledge organization work be extended from institutions to individuals. It is also suggested that knowledge organization work responsibilities are broadened to involve authors, knowledge workers, and information users rather than restricting it only to trained information professionals. The paper highlights that the digital environment makes it necessary to change the context for teaching KO courses and goes beyond the collection of information resources and addresses personal information management needs as well. The paper concludes that fundamental changes tantamount to re-conceptualization of the area of knowledge organization, which is expected to open up new opportunities for information graduates aspiring to work in information environment beyond libraries.

This study is on the reading method of Korean old poetry in the digital age. Now days, we are living in digital media. The method of getting, organizing, and producing information is changed a lot. So for keeping pace with this change, we should reflect our teaching method. Of course, the purpose of our reflection is not to follow digital media's method and change or alter existing reading or teaching method, but it is to identify proper own reading strategy of old poetry and adjust existing method for our student who are skilled with digital media. We propose three kinds of method for student readers in school. These are 1) starting like a newspaper reader, 2) getting context (reading, making hyperlink), and 3) figuring as an architect (reading as space or scenery creator). In addition, we think about recent tendency that Korean old poetry is de-constructed and re-constructed as digital contents in digital space. We call it digitalizing of old poetry. The experiencing old poetry as a digital contents is different from reading old poetry, so we cannot alter old poetry reading experience into experience of digital contents. In conclusion, digitalizing contents should be used restrictively to fertilize reading experience of original old poetry.

Probability has distinctive characteristics which are different from other areas of school mathematics. The critical change can be noticed in the domain, 'probability and statistics' of 2009 revised national curriculum for elementary school mathematics. This indicates that the concept of chance is supposed to be taught in the 5~6 grade band instead of the definition of probability which is moved to the middle school level. The purpose of this study is to seek desirable methods for teaching the concept of chance which reflect the achievement criteria and the attention point for teaching and learning of the curriculum at the point of time when textbooks haven't yet been developed. To do this, based on theoretical considerations and comparative analysis of the curricula in the longitudinal - latitudinal dimensions respectively, the validity of the latest curriculum change was confirmed and several learning activities were devised. And then two lessons were planned for applying these activities to eight fifth graders and were implemented along the plan. As a result, the relevance of the learning activities was examined and students' difficulties in learning the concept of chance with educational implications were discussed.

This Qualitative study investigated a preservice teacher's developing views of learning with the influence of constructivist epistemology taught in the Math, Science, and Technology Education (MSAT) Master of Education (M. Ed.) preservice teacher education program. The MSAT teacher education program employs constructivist aspects of teacher education and generates applications of constructivism to the practice of teaching, as revealed by faculty interview data. It is important at this point to emphasize that there are significant epistemological and ontological differences between different versions of educational constructivism (i.e., individual, radical, and social constructivism) and that these differences imply different pedagogical practices. For the 16 preservice teachers included in a larger study, the epistemological and ontological characteristics for each teacher's developing views of learning were identified through four in-depth interviews. Data from interviews were used to construct a constructivist profile for each preservice teacher's views of learning (i.e., a profile containing ontological beliefs, epistemological commitments, and pedagogical beliefs). Of the sixteen participants in the larger study, five significantly changed ontological and epistemological beliefs and eleven did not. Profile changes for the five who did change also resulted in changes in their conceptions of science teaching and learning (CSTL). In this article, one of the five teachers case was presented with rich quotes. This case study documents how a preservice teacher transferred his ontological and epistemological beliefs to his pedagogical beliefs and maintained the consistency between his philosophical beliefs and CSTL. It also demonstrated implications that changes in components for an educational constructivist profile have for a preservice teacher's view of himself as teacher. Data indicated the possibility that a constructivist-oriented preservice teacher education program can influence students' conceptions of science teaching and learning by explicitly introducing constructivism as an epistemology rather than as a specific method of instruction. Implications for both instructional practices of teacher education programmes and research are discussed.
