The purpose of this study was to investigate the middle science teachers' perceptions on science lessons with experiments. The study conducted a survey for 110 science teachers participating in inservice program. The middle school science teachers taught classes with lectures rather than with experimental activities. They had an experiment one to three times a semester in their lessons. They did an experiment to follow to what the textbook said, or to confirm it, like a cookbook style. The most teachers answered that they had over average ability to teach both lecture and experiment. Through the experiment, they expected students had interests and curiosity on science. Despite the advantages of experiments, there were many constraints to conduct experiments, such as teachers' excessive work, laboratory conditions, education environment, and others. It was demanded on continuous interest and investment in the variation of educational environment so that teachers can experiment more often.

The purpose of this study is to understand the public education system in Korea, that features many pre-taught students, and to figure out how elementary school teachers teach them. To accomplish this study, 204 elementary school teachers in Seoul participated in a survey and the frequency and percentage were made. In addition, to add more depth to this study 5 elementary school teachers had several interviews. We obtained the following results. First, elementary school teachers generally think that the situation with many pre-taught students have had a bad effect on public education and pre-taught students are drilled but cannot understand what they have learnt. They also answered that they have low morale when teaching pre-taught students. Second, a large number of elementary school teachers think the situation with many of the pre-taught students does not help the public math education system, which influences the teachers' teaching style. Teachers who answered negative on pre-taught students are running their math classes focusing on understanding math concepts and activities. On the other hand, few teachers who answered positive on pre-taught students did not care about the situation with many pre-taught students.

In this study, science teachers' perception and attitude toward nanotechnology are examined through questionnaires gathered from 134 secondary science teachers. As a result, the study shows that science teachers have high perceptiveness. However, they do not understand specific information on nanotechnology correctly. Science teachers have positive attitudes toward nanotechnology and they have perceived risks of nanotechnology as well as benefits of nanotechnology. Science teachers show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chip and nano-taste enhancer. Science teachers are exposed to nanotechnology via various sources such as TV and internet, whereas teachers rarely get information on nanotechnology-related concepts in textbooks and teaching resources. Science teachers have perceived many textbooks do not introduce enough nanotechnology-related concepts. Many teachers try to explain the nanotechnology when textbooks include nanotechnology-related concepts, whereas quite a few of teachers do not introduce the nanotechnology-related concepts in class.

For difference test, ${\chi}^2$ tests were conducted. The results of this study can be summarized as follows. First, both nursery teachers and kindergarten teachers perceived that listening and playing were the most important factors in effective interactions between young children and teachers. However, nursery teachers perceived the interaction through skin-ship and complimenting to be more important whereas kindergarten teachers perceived questioning and complimenting as necessary. For the teaching criteria, nursery teachers put more weights on playing while kindergarten teachers focus more on explaining and coorperating. In addition, about evaluation methods, nursery teachers perceived self-evaluation as important, whereas kindergarten teachers perceived observation notes as important. Second, about the elements to strengthen teaching competence, nursery teachers perceived that observation records should be utilized for understanding interest or desire. They also believe that development analysis and teaching methods should be improved through systematical teaching plan and evaluation and that enhancement of teaching material and education are necessary. In contrast, kindergarten teachers perceived that observation records should be utilized for teaching plan and development analysis and teaching methods should be improved through participating in the meetings related to career and education. They believe that providing a prize money through supervising evaluation is necessary.

One of the main purposes in prospective elementary teacher education is to prepare for teaching each subject matter. For this purpose, it is necessary to explore how prospective teachers may analyze elementary mathematics instruction and they perceive their analytic foci. This study probed in what ways prospective teachers analyzed elementary mathematics instruction using two video cases. The results of this study showed that prospective teachers focused mainly on instructional strategies, specifically with regard to whether such strategies would be adequate both for mathematical content to be taught and for students' characteristics. They also focused on the effective use of instructional materials as well as the case teacher's adequate feedback. Prospective teachers claimed to have analytic foci not only on the degree of attainment of instructional purposes but also on students' responses and interest. Given this result, this paper includes several issues related to help prospective teachers prepare for better teaching.
