Orthogonalized Slater-type orbitals and Ortho-normalized Slater-type orbitals were derived from the conventional Slater-type orbitals (STO's) by use of the continuous orthonormalizing which is expanded from the Schmidt's orthogonalizing procedure. These orbitals have the merits which STO's have not, such as; they are ortho-normalized each other and have the same numbers of the radial nodes that the real hydrogenlike wave functions do, so that they must be a good basis functions of LCAO MO procedures, i.e., the best approximate representation of SCF method.

This paper describes a design scheme of a system that tests or polls from the students at online class. By online test, the teacher can test the pre-knowledge level of the students and know how much students understand the lecture of the class. As the number of test increases, the burden of the preparation of setting question, evaluation of the test, and management of the test results is increased. In this environments, an online test management system make it easy to test and evaluate, and thus it would be a good tool for maintaining and managing the total procedure of the test or poll of the students. For evaluating the design of the system, we made a test system prototype and performed evaluations of the online test system. The online test and evaluation system provides a good tool for testing and evaluation of student's knowledge at the class with easy and fast way.

The purpose of this study was to research and compare teachers' preferences for 'Great Math Class' by region and gender. The research was conducted on 261 high school math teachers by using non-probability sampling. As the results of the study, regional preference had no statistically significant difference in all four factors of 'Great Math Class' while gender preference had statistically significant difference only in the factor of teaching (methods) and learning methods. Both region and gender had statistically significant positive (+) relationship with preference for all four factors. This implies that it is necessary to consider socio-cultural factors rather than teachers' perception on class for regional differences in academic achievements in mathematics.

As for newly establishing a NE subject, 37.9% of the teachers disagreed and as for most effective method for NE, 73.3% answered NE linked with school lunch program. Most of teachers recognized elementary school students' eating habit problem severe and change of their eating habit such as various food choice, no plate waste and good table manner after school lunch program. Therefore, it should be nationally supported that a standardized NE program is developed and coordinated among teachers, school lunch dietitian as NE specialist, family and community for elementary students' health and well-being.

The purpose of this study is to investigate the necessity, selection, organization and management of Must Books List in middle schools. A great book can change a person's life and future. Especially, reading in the juvenile period is important because of their intellectual curiosity and sensitivity. The results of the study were as follows: 1. The necessity of Must Books can be considered in two perspectives : One is the cultivation of emotion and sense of value and the other is the development of information abilities. 2. The general criteria for the selection of Must Books are whether a book is su n.0, pportive of learning activities, of extracurricular activities, and of activities for school festivals. And whether a book is contributing to the building of good characters of students or not should be considered, too. 3. The special attention should be given to such matters as the organizational and distributional ratio among subjects of the Must Books, the degree of difficulties, the ratio of books for both male and female students, the ratio of foreign books to domestics, the possibilities of further reading and the bibliographical matters. 4. The points to be duly considered for the management of Must Books List are the educational considerations, clearness of objectives, the elimination of commercialism and authoritarianism in the book selection. The Must Books List should be managed autonomously, depending on the characteristics of each school and be updated annually. However, the most important thing is that the teacher should be a good reader himself. 5. It is better to include short stories than the long one in the Must Book List. Students should be guided to read explanatory text first and then to move to the original text. And they should be exposed to books in various subjects and not to be too dependent on the Must Books List. They should be able to develop the problem solving ability through the reading of the Must Books. 6. Finally, the Must Books selection committee should be composed of both teacher librarian and subject teachers. It is desirable that books for the cultivation of emotion, for the establishment of sense of value, and for the development of information ability should be selected by consulting the various reading lists compiled by the Ministry of Education, the Board of Local Education and other authorities concerned.

Through the criticism and evaluation of different classes teaching the same lesson topic, this study compared the viewpoints by two ways between two groups including pre-service and experienced teachers. Through free-style criticism, this study analyzed the differences between pre-service and experienced teachers' areas of attention. Through criteria-based analysis, the study analyzed the judgement of each area and the criteria of each judgement. The results of the study found that pre-service teachers criticised more limited areas, but somewhat more positive than their experienced teacher counterparts. Also, pre-service teachers did not observe thoroughly whether or not the teacher was well-informed of the science content, the sequence of curriculum, and whether or not meaningful interaction had occurred. As well as, pre-service teachers were not actually feel importance of student-oriented lessons, and they could not look room and materials are useful to students on students' sides. Additionally, pre-service teachers thought highly of lessons which were connected to other subjects rather than connected to daily life. Therefore, to notice diverse areas in the class, pre-service teachers need to criticise lessons using a diverse criterion. Also, pre-service teachers realized simple questions and that mechanical group activities are not always effective and that they need to think how to improve meaningful interaction. Moreover, they have to perceive that an inquiry-oriented student-lead approach is very important. Lastly, pre-service teachers have to closely consider the room efficiency and materials available to the students, and they must internalize that science class has to be connected with daily life.
