The purpose of this study was to investigate the effects of memory retention of mathematical concepts in multiplication in the inquiry-based pantomime instructions. Three months later after the pre-test, a comparison was made between traditional class (TC) and class with the inquiry-based pantomime (IP) approach in terms of students retention of mathematical understandings. Results of the study indicated that the If instructions promoted effective long-term retention of knowledge. We concluded that instructional strategies that promoted active engagement in learning using life examples and drawings produced effective long-term retention of knowledge.

Inquiring earth science phenomena is characterized by the followings: a big scale of time and space, inaccessibility, uncontrollability, and complexity. Thus, it is very difficult or, in some cases, impossible to investigate them through the actual manipulation in laboratories. Therefore, it is necessary to provide chance for students to experience scientific inquiry without actual manipulation in earth science classes. This study is to explore the role of reasoning based on a thought experiment as a representative model without actual manipulation, and to investigate features of various inquiry models using reasoning in classes. We can make implications when applying for applying each inquiry model to earth science classes, proposing a reasoning-based inquiry model embedded in earth scientific phenomena.

The purpose of this study is to critically review the skill-based approach to scientific inquiry in science education and to explore the meaning of science practices that are emphasized in recent science education reform movement. An extensive review of relevant literature was carried out, and the results were summarized according to the detailed themes of the study. In the skill-based approach of which Science-A Process Approach (SAPA) is a representative example, science process skills were presented as hierarchically connected with one another, they were believed to be transferable or generalizable, and science learning through discovery was stressed. These points of view are, however, contradicted with those of the modern philosophy of science which suggests the theory-laden nature of using the skills. The skill-based view has also been criticized by the fact that the use of inquiry skills is content-specific or context-dependent and that science theories or principles cannot be discovered by induction. In contrast, the recent view understands science practices holistically, emphasizes the diverse ways of doing the practices which vary with different contents or contexts, and considers student ideas importantly in the science classroom. The findings of this study can contribute to the development of a new science curriculum by providing implications for establishing a consistent view on scientific inquiry.

The purpose of the study was to suggest the characteristics and goals of the science teaching model for use as criteria in selecting the appropriate teaching model for science in secondary schools. These characteristics and the goals have been organized based on the analyses of the literature on the teaching and/or instructional model. The teaching models have been classified into four areas, and the characteristics and goals of each area have been summarized as follows: $\cdot$ Traditional models: teaching of scientific knowledge through lectures, acquisition of scientific knowledge through discovery, acquisition of inquiry process skills through inquiry-based teaching/learning $\cdot$ Transitional models: demonstration and discovery as teaching strategies, acquisition of inquiry process skills through inquiry approach, acquisition and change of scientific knowledge $\cdot$ Modernistic model - conceptual change models: differentiation of scientific knowledge, exchange of misconceptions for scientific concepts - learning cycle models: conceptual differentiation, exchange of misconceptions, acquisition of science process skills Also described in this paper are the model's characteristics and goals that can be used as the criteria for selecting the appropriate teaching model for the subject that will be taught.

The purpose of this study was to select words with "shared cultural charge" that are unique in French culture and to study cultural content hidden in these words. It also explores the cultural phenomenon of same French borrowed words used in the Korean language. The study was conducted from two perspectives: perspective of internal French culture defined by Galisson and inter-cultural perspective. The first section of this study introduces the theory "lexiculture" and definition of the words "shared cultural charge." In the following section, among main items of 795 borrowed words in the Korean language, we examined seven words in areas such as clothing, food, and housing. We studied content of the French culture according to the following three categories: (1) dictionary definition, (2) cultural phenomena, (3) special phenomenon in idiomatic expression. Our study illustrated a special connotation beyond the dictionary definition of words. In the next section, we examined the birth of a new cultural phenomenon and process of acquiring a new meaning in the Korean language. Finally, we analyzed differences and similarities between linguistic and cultural elements in both cultures. In this study, we provide basic data for inter-cultural education between France and Korea.

In learning activities. research learning is mostly carried out in a laboratory. Learners can approach a learning process with ease and are given the chance to do the self-directed study one research experiments in advance by designing a process of research learning in the laboratory by a web-based simulation courseware. And this can offer a learner-centered model with which learners can share. exchange and interact information each other. Using a web in instructing and learning can be an appropriate implement of research and also gives learner-centered learning environment. This thesis is a study on design and implementation of a web-based simulation courseware for learning Kinetic energy through the research learning which is one of the self leading learning methods.

In elementary, environmental education have been doing in various subjects. The features of environmental instruction would be reflected on contents of environmental education and characteristics of each subjects. These contents of environmental education might be contained normative contents, and it is moral subject that treats these normative contents systematically. Then environmental instruction of moral subject in elemental school should be approach and inquire teaching contents related to environment education. In elementary school curriculum of moral subject, teaching contents related to environment are 'preciousness of life' and 'right views of Nature and protection of the environment'. By these contents, moral instruction can approach to life of animal and plants centered on the reason to take them preciously and relation between nature and humans centered on the moral consideration. It is a difference that approaches to the environmental education not by factual understanding but by normative understanding in moral instruction. It must be focused on ethical inquiry for normative approach and reserving identity of moral subject. Necessary conditions for ethical inquiry to the environmental instruction are moral status of things besides humans. For the ethical inquiry to the moral status of nature environments, teachers could be set the logic of instruction based on the developments of environmental ethics. Formal cohesiveness of environmental instruction could be developed in sequence of ethical inquiry on moral status to the life of animal, life of plants, and whole system of nature. For this, teacher could reflect on their instruction focused on some explanations. That is, it is explanation to the animal life based on the individual-extended human oriented ethics for human, plants life based on the individual-non human oriented ethics, whole natural system based on the holistic-non human oriented ethics. When teachers reflect these explanation, they can compose their instruction as 'finding something in common with humans and animals', 'reflection on the attitude to the commons', 'thinking about reasons on the different attitudes to the commons', 'the things that disappear as plants die', 'thinking on values about non organism'. These plan of instruction could be critically reconstruct by other teachers. But environmental consciousness by ethical inquiry should be hold on instruction to the environment reflected on identity of moral subject.

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.
