For teaching-learning to geological region of earth science part in science education, middle school, the practical uses of natural science museum are very effective. So, the appropriate uses of the natural science museum are necessary for the teaching and learning of Science Education. This study aims to consider the presentation characteristics of the natural science museum and to examine how is effective it to geological region in middle school science curricula on those uses. From the results, the natural science museum is low in multi-sided and open-endedness presentation characteristics but high in ones of accessible characteristic. And its presentations are good in multimodal characteristics using supported materials but relatively low in relevant and multimedia ones. In the museum, diorama and self-performing presentation types are not but internet ones are most. The presentations of the natural science museum are mainly assigned to knowledge region linked to basic science concepts but relatively insufficient in STS aspects, on the basis of connection the presentations with middle school science curricula. It is respected that these insufficiencies might be diminished by variable arrangements of and explanations to the presentations for understanding improvements. And, applies to the presentations in STS may be encountered, if multi-sided observations to them is available.

This paper investigates the teaching and learning of Linear function relating functional contexts and suggests the improved methods of representation-shift through this analysis. The methods emphasize the link between students' preacquired knowledge of mathematical representations and the way of using those. This methods are explanatory teaching, teaching and teaming based on modelling perspectives or tasks (interpretation, prediction, translation and scaling). We categorize the 8th grade middle school students' errors on the linear function relating real contexts and make a comparative study of the error-remedial effects and the teaching and teaming methods. We present the results of a study in which representation-shift methods based on modelling perspectives and tasks are more effective in terms of flexible connection of representations and error remediation. Also, We describe how students used modelling perspective-taking to explain and justify their conceptual models, to assess the quality of their models and to make connection to other mathematical representation during the problem solving focusing on the students' self-diagnosis.

Investigation on the appendices was carried out to acquire teaching materials about improvement of a appendices and development of teaching-learning activities for science textbooks in Korean middle schools. We analysed the appendices for 30 kinds of science textbooks used in Korean middle schools during $1969{\sim}1994$ years. In the results there were three kinds of pattern for the appendices, such as appendix, non-appendix, and similar appendix without appendix title. The content of appendices were summarized as six categories. such as list of science and scientist history, SI unit-constants and symbols, handling methods of instruments for basic experiments, measuring methods and inquiry activity, safety and precautions, and supplementary data with figures and tables. The appendices of six categories were mostly a content of general and integrated science, and were concentrated in the first grader's textbooks. There were many appendices about the methods for basic experiments such as 'How to Use of Experimental Appliances' in the first grader's science textbooks, but there was no or lack of them in the second and the third grader's science textbooks in the middle school. By the ratio to the pages of appendices which were included according to curriculum changes. the ratio was found to be 4.47% which was the highest in middle school science textbooks at the second curriculum and to be 3.47% which was the highest in high school biology textbooks at the second curriculum. The results of this study indicated that the science textbooks should include as many appendices as possible, because teachers could utilize them in teaching activities and students should be able to be given much help in self-learning.

The purpose of this study is to analyze ego state types of teacher librarians by using egogram of the Transactional Analysis. It is the ideal ego state types for teachers that NP (Nurturing Parent), A (Adult) and FC (Free Child) are much higher than CP (Critical Parent) and AC (Adapted Child). But the teacher librarians are under higher CP and AC rather than A and FC. It means that the teacher librarians consider their values and belief as right things. Also it seams that they have not a conciliatory attitude but a hardened attitude that emphasize rules and standards. These ego state may be obstacle to their instructors role under the constructivist learning environment highlighting self directed learning of students. So, in the training course for the teacher librarians, informational and educational service course and development programs of education contents and instructional materials should be reinforced in order to strengthen their teaching competence and partnerships.

In this paper, an intelligent robust control system (IRCS) for precision tracking control of permanent-magnet synchronous motor (PMSM) servo drives is proposed. The IRCS comprises a recurrent wavelet-based interval type-2 fuzzy-neural-network controller (RWIT2FNNC), an RWIT2FNN estimator (RWIT2FNNE) and a compensated controller. The RWIT2FNNC combines the merits of a self-constructing interval type-2 fuzzy logic system, a recurrent neural network and a wavelet neural network. Moreover, it performs the structure and parameter-learning concurrently. The RWIT2FNNC is used as the main tracking controller to mimic the ideal control law (ICL) while the RWIT2FNNE is developed to approximate an unknown dynamic function including the lumped parameter uncertainty. Furthermore, the compensated controller is designed to achieve $L_2$ tracking performance with a desired attenuation level and to deal with uncertainties including approximation errors, optimal parameter vectors and higher order terms in the Taylor series. Moreover, the adaptive learning algorithms for the compensated controller and the RWIT2FNNE are derived by using the Lyapunov stability theorem to train the parameters of the RWIT2FNNE online. A computer simulation and an experimental system are developed to validate the effectiveness of the proposed IRCS. All of the control algorithms are implemented on a TMS320C31 DSP-based control computer. The simulation and experimental results confirm that the IRCS grants robust performance and precise response regardless of load disturbances and PMSM parameters uncertainties.

This study examined how 132 teachers of different grade levels incorporate the key competencies identified by Korea Institute for Curriculum and Evaluation into their mathematics teaching and how they perceive of its full potential of the competency-based learning and teaching in mathematics classroom. Survey and semi-structured interview methods were used to collect data for the study. It was found that in their instruction teachers emphasized competencies such as problem-solving, literacy, creativity, communication and information-processing skills in order. Inter-personal skills, self-management, citizenship, global understanding and career-development appeared to be challenging competencies for teachers to reflect in their instruction with the reasons such as no direct connections to mathematics and insufficient instruction. Findings of the study suggest that various instructional methods, development and dissemination of related curricula materials, change of evaluation method, and change teachers' perceptions may be needed for incorporating KICE's key competencies in K-12 mathematics education.

According to the changed '2+4'-year pharmacy school curriculum in Korea, pharmacy preceptors play a highly crucial role in educating student pharmacists through practice-based learning. Whether the new curriculum in a Korean pharmacy school will become firmly established or not depends on the competency of a preceptor. Before the preceptors with high competencies are anticipated, the effective education programs for them should be provided. However, there have been little studies regarding the competencies of pharmacy preceptors in Korea. This study was to analyze the degree of differences between importance and performance of preceptors' competencies. The self-reported questionnaire was utilized to collect data from pharmacists in the preceptor education program of a university. Total 122 pharmacists participated in the program, and 78 responded to the survey questionnaires. The average of importance for overall evaluation items was 4.32 whereas that of performance for them was 3.51 by using a 5-point Likert scale. The evaluation items with relatively marked differences between importance and performance were 'sufficient time allowance for students', 'teaching research results regarding newly approved drugs', 'clear understanding of goals and learning contents about pharmacy practice experiences', and 'plan for systemic experience educations'. Further follow-up researches on changes of the differences in importance- performance of preceptors' competencies after precepting student pharmacists should be implemented. Furthermore, the effective and appropriate methods for the preceptor education programs based on the follow-up studies should be developed to reduce the difference between importance and performance.

Programming education generally includes problem analysis process, automation through algorithms and programming, and generalization process. It is a good software education method for students in improving computing thinking. However, it was found that beginners had difficulties in understanding instruction usage, writing algorithms, and implementing programming. In this study, we developed a game programming education model and curriculum for programming education of pre-service teachers. The 4E model consisted of empathy, exploration, engagement and evaluation. In addition, it is configured to learn game core elements and core command blocks by each stage. To help the pre-service teachers understand the use of various programming blocks, a three-step teaching and learning method was presented, consisting of example learning, self-game creation, and team-based projects. As a result of applying and verifying the curriculum for 15 weeks, it showed significant results in the 4E model and pre-service teachers' perception of block programming competence and the level of computational thinking on the submitted game project results was also high.
