In this study, chemistry teachers' noticing of high school student's chemistry problem-solving materials was explored. Fourteen high school teachers participated in the study. We created materials documenting student's problem-solving processes and conducted semi-structured interviews with teachers. The results of the study revealed that most teachers only paid attention to errors in student's scientific thinking, and the number of teachers who paid attention to scientific thinking partially or completely was the same. In interpreting, teachers were most likely to provide an exaggerated interpretation with evidence, followed by a correct interpretation with evidence, and an incorrect interpretation with some evidence. In responding, many teachers suggested responses that aligned with student's thinking, with slightly more aligning with student's specific thinking than with general thinking. Teachers who suggested actions that aligned with student's specific thinking tended to be content-focused, with some vague or off-target responses. Teachers who suggested responses that aligned with student's general thinking tended to be similar to those who suggested responses that aligned with student's specific thinking, but neither type of teacher suggested student-centered responses. Some teachers suggested responses that did not align with student thinking. Based on these findings, we discussed ways to improve teachers' noticing of student problem-solving.

This study aims to investigate how learning materials are used in an outstanding English class and to analyze learning materials and their use in primary English classroom activities. To this end, An Analytic Scheme of Learning Materials Use (ASLMU) is used to quantify utilization patterns of learning materials. The findings are: Learning materials are most actively used in the development period, followed by introduction and consolidation. The teacher's rate of using learning materials is much higher than student's, and the rate of using materials for whole students is higher than the rate of using materials for an individual or groups. It requires developing learning materials toward more a student-centered class because the teacher's occupancy of the learning materials is fourfold compared to the student's occupancy. Also, non-language materials are used more than language materials, and English materials are used more than Korean materials. Most of the materials are used to present a question and explain. The findings of the study are expected to suggest features of learning materials in an outstanding English class and application method of learning materials to primary English teachers.

Our country has been consuming a huge amount of energy in the course of industrialization and its demand is expected to increase enormously in the future. However, the deposits of energy resources are so limited that the settlement of energy problem comes up the essential subject. To solve the energy problem, it is requested that new resources to gain energy stably should be developed and also energy should be economized and used effectively. The effective use of energy and an the wisdom of economy in energy are requested to everybody and these things should be habitualized from very young age through education. Nevertheless, almost every school in our country hasn’t been concerned about energy education. Even though they have a concern, they are very short of the energy education materials and the quality of the materials is not so good. Therefore it is very meaningful to the settlement of energy problem of the country to make the students who will lead our country to make the students who will lead our country in the future realize the seriousness of energy problem and to provide them the necessary knowledge and methods to solve this problem so that they practice those things in everyday life. Having these necessities, this research, supported by The Korea Energy Management Corporation(KEMCO), was performed for 8 months from April 17, 1994 to December 17, 1994. Many peoples participated in this study such as 30 staffs of researchers and authors, 5 staffs of photographers and illustrators, and 3 VCR program producers developing an energy education material set for middle school students that includes a printed material for student, a diskette for computer simulation, a teacher's guidebook, VCR material and its guidebook. The following main development direction was established : First, the material for student should be consisted of units that let students know the seriousness of energy problem. Second, the focus should be put on the necessary method and practice to economize energy actually in real life based on the basic knowledge learned in elementary school. Third, material for student should be consisted of modules to be student activity-oriented teaching-learning rather than lecture-oriented one. The activity, to maximize student's interests, should be presented in various forms such as experiments, investigation, play, data interpretation, computer simulation, visits, expression and appreciation, etc. To develop the energy education materials for middle school students, a research plan was made first. After literature review about domestic and foreign energy education materials, several research trips home and abroad, and discussion meetings, the basic theory of energy education such as the principle, objective, contents, teaching-learning method, and evaluation method was established. Material for student was developed through the following procedures : The activities in the existing energy education materials were analysed and were divided into four categories related to energy using places of home, school, community, and country, and which were again divided into three categories related to time of past, present, and future, Considering these division, nine modules which are structure units of material for student were chosen, Each module comprises 2-4 activities. Totally 31 activities were designed in this way. The syllabi were made out for each activity and writing was asked for to experts related to each activity after several discussions and revision. To complement the draft, another several discussions and revision were also made on it and then pictures and illustrations were asked for. All these procedures complete the material for student, titled ; Energy Inquiry of Middle School Students', which totals 129 pages and is all in color. As the manuscript of material for student was fixed, writing for teacher's guidebook was asked for to the same writers. The draft of teacher's guidebook was also complemented through the several concentrated works and discussions. Teacher's guidebook focused on the teaching-learning principle and methods of energy education and on the concrete instruction cases for effective instruction of material for student. It is organized with two parts : the one is 'general outline' which introduces theoretical contents and the other is 'details' which are practically helpful to teaching-learning. It is totally 131 pages including both 'general outline' and 'details'. The VCR material and its guidebook consist of contents that cultivate the good attitude trying to economize energy and raise student's interests with a purpose of strong motivation to recognize the necessity of economy and practice it. After establishing development direction of VCR material through discussion meetings and research trips, its script was made by relevant experts. Then the script was also reviewed two times. The drafted VCR material made by a video material developing expert was examined and modified by previews twice. After completion of VCR material, the VCR guidebook was made. All these procedures led to the development of VCR material which runs 20 minutes in VHS type. The VCR guidebook shows a production purpose of the program, structure of contents, evaluation methods, and contents of the program in detail to give help to instructors when they use this VCR material, When these energy education materials are used, it is desirable that the VCR material should be presented first to induce student's motive, and then material for student is introduced Since the material for student is composed of activity-oriented modules and each module is independent one another in general, and each activity is, too. the necessary module or activity can be chosen and utilized in any order according to school or class conditions. This energy education materials will contribute to the development of student's ability to solve energy problem in everyday life and teacher's ability to teach the fundamental knowledge and method in solving energy problem.

The future society will demand that enables one to solve in many fields by connecting various informations in many fields and then creating his own information. In the coming society, creativeness will be regarded much important. This ability can be developed with materials through group activities experimental class in math classes. This classes using these materials are not teacher-oriented, explanatory classes but student-oriented ones. They offer students opportunities to think by themselves and expand their potential abilities. They are suitable for rising and keeping student's interests. Therefore experimental classes through group activities enable students to think mathematically and make them recognize the importance of mathematical approach by letting them work connecting other subjects or things in real life. They can develop not only expressive, communicative ability and cooperative spirit, but also the ability to transcend the class itself and then reorganize facts in new insights. Besides, math classes with experiments can arouse student's curiosity familiarizing them with mathematics. Moreover, they can expand student's originative and problem-solving abilities.

It is necessary for lower grade students to study the correct usage of tools as a base of the technical education for dismantling and assembling various machines. However, enough understanding has not been obtained though the usage of these tools when training first grade students. So, we started to develop a teaching text and materials within the students' practice curriculum based on the dismantling and assembly of all-terrain vehicle [ATV]'s, which is a very motivating for lower grade students. This practice makes the student learn both how to use the tools and the steering mechanism of cars through the dismantling and assembling of the ATV. It is possible to not only have the student learn about the knowledge obtained through the practice, but also they also acquire wider and deeper knowledge through making the text and teaching materials for the practice. The textbook and secondary educational materials of this practice curriculum were created in cooperation with a fifth grade student as part of their graduation research. As a result, an effective teaching and learning text and secondary educational material regarding manufacturing practice could be developed from the student's point of view. Making a teaching text and materials is effective for promoting the study and experience of engineering.

We are focusing on an approach which handle a general Web as a resource in order to support self-directed learning for a student. Then, we are developing a Web based learning environment "Web-Retracer"for utilizing Web as teaching materials by a user′s Annotation. Although the learner can share the Web resource that the others utilized in this environment, Web resources unsuitable for a student′s needs becomes hindrance about her/his self-directed learning. In this paper, we propose a recommending method of the resource united with a student′s needs on the basis of a student′s learning and Web browsing history. This method analyzed the feature peculiar to a resource, and extracts the resource with which the needs of the feature and a student agreed.

In the radically changing market situation, surface materials of student furniture are a very important element to decide the consumption pattern and the market price. Thus, this study examined the characteristics of surface materials by classifying the student furniture into children's, juniors', and seniors' furniture while accessing the features of such surface materials through Glulam, veneer, poly paper, finishing foil, high pressure melamine (HPM), and low pressure melamine (LPM), and PVC vinyl. When taking a look at the surface materials that were most frequently produced in each domestic furniture company, the combined materials that used more than 2 elements (31.88%), LPM (23.19%), and Glulam (20.29%) were introduced at the market in the order. Regarding the analysis made on colors, the combination colors took more than half (55.32%) followed by brown (13.83%) and beige (11.7%) in the order. Based on the results derived from the analysis, the study suggests to stress more importance to surface materials when developing student furniture and to exert efforts for the consistent development of new materials and quality improvement, as a way to accelerate the development of the furniture industry in Korea.
