We investigated the characteristics of lesson session and the professional development of teachers who conduct good teaching science subject. Seven teachers' were selected the finalists at the elementary school science and teaching competition. The study was based on a semi-structured questionnaire and interviews. To prove validity of the study, the collected data were verified by subject teachers for feedback. The results showed that the teachers believed that their lesson contents and methods were superior to other teachers. To enhance professional development in their lessons, they are only being made through help from colleagues and personal efforts, and a systematic development was involved with necessary situation. As a plan for enhancing an effective quality enhancement of lessons, open classes and conversation between colleagues were proposed. An organization or a group that can motivate teachers and provide systematic support for quality enhancement of lessons by teachers is needed.

Teaching and learning were carried out long before the word "education" was coined. As teaching and learning became more universal, the word "education" was construed as a social promise, and there was a general consensus as to what it denoted. Many university professors will most likely have great confidence and expertise with respect to "teaching" in their area of specialization, and they believe that they are fulfilling a social promise. However, how much expertise do they have in actually making students "learn"? How concerned are professors about enabling students to utilize their potential and talents to cultivate their learning abilities and to adjust to the different demands of various fields? The same issue arises in medical education. To what extent can professors' teaching heighten students' sense of purpose and motivation to learn? With regard to increasing learners' initiatives, the learning model of constructivism presupposes that learners are active and creative, have their own personalities, and possess unlimited learning potential. The PBL being carried out in medical schools today is a form of study that can take advantage of these aspects of learners. They can maximally widen the range of students' development through many intellectual activities and solve difficult problems by either sharing or critiquing the thoughts and ideas of others. The acts of teaching and learning that have been carried out for thousands of years remain difficult to this day and must be ceaselessly deliberated and researched by experts in the field of education. Just as good teachers are required to produce good learners, we must give ourselves room to rethink the basis of education in order to maximize effective and efficient learning.

The purpose of this study was to explore science teacher's epistemological understanding of science and science teaching and learning, from the perspective of inquiry as the process of scientific knowledge building. Three science teachers participated in this study. The data were collected from individual in-depth interviews and classroom videotaping. The results show a case involving coherent and consistent data. It showed that the teacher's epistemological understanding of science and science teaching and learning consisted of five categories: scientists doing science with scientific thinking; scientific thinking as the process of knowing; science learner in the learning process of scientific thinking; science teacher as a man/woman with good understandings of science; and teaching and learning as the process of knowing science. Based on the results, discussions and implications about science education and science teacher education were presented.

This study has been undertaken in the light of constructivist view of teacher education. Participant observation, unstructured interview and questionnaire were used to explore the process and the role of practicum in science teacher education. The subjects were 19 student teachers majoring in physics education; 8 had participated at boys junior high school, 11 at senior high school. The student teachers had very critical and negative perception on their school days' science lessons. They had expected to do 'better' in their practicum but there were only 3 to 5 opportunities of teaching under the umbrella of textbook. Explanation in the classroom and solving exercise problem were the main features of student teachers' lessons. Much of the lessons were similar when it is to same topic and the main reference for their lesson preparation was the textbook. The student teachers felt the design of teaching approach as the most difficult thing during their lesson preparation. They realized that teaching is harder than they thought and they should consider students' level and responses. Though they had become to have more positive perception on teaching job through their field experiences, their decision on job preference did not change. More than half did not want to be a teacher. The student teachers recognised the courses related with science education as the most useful to their teaching in practice among the program of college of education which they had taken. The experience of writing one lesson plan or teaching in front of their peers, designing a new demonstration equipment were recognised as valuable and helpful element of the courses. They proposed to reduce the amount of general education courses and to emphasize the courses relevant with science education and practicum. The limited opportunity of teaching in practicum was pointed out as problematic. Though the practicum was recognized as a 'good' experience to student teachers, it was confined by textbook and limited teaching opportunity. In conclusion, the practicum was not organized and implemented as a meaningful experience of science teaching and learning. There should be more structured studies on what kind of perceptions and experiences the student teachers had brought to the science teacher education program, how they interact with the elements of the program and how they affect to their science teaching. The structure and content of practicum also should be studied and developed so as to make practicum as a meaningful experience of science teaching and learning.

In this study, we investigated teachers' experiences in teaching with the science museum as well as their confidence, their perceptions, educational needs, and their willingness to practice the instructions using science museum. A survey was administered to 225 elementary and secondary school teachers. The analyses of the results revealed that few teachers had training for the instructions using the science museum and not many teachers had experience in teaching with the science museum. Many teachers were also found to have low confidence in teaching with the science museum. Although the teachers had a relatively good understanding of the educational effects, nature and teaching strategies for the instructions using the science museum, they tended to apply the formal views on science teaching/learning to learning with the science museum. The levels of willingness to use the science museum in their instructions and educational needs of the instructions using the science museum were high. They wanted the information about practical aspects to use in the instructions using science museum most. Educational implications of these findings are discussed.

This study purposes to figure out the effects of applying discussion-based science class on concept of science achievement and science teaching efficacy. This study established an twelve-week period of experimental treatment from April to June 2019, and the students who participated in this study formed a research group consisting of 27 students in the first semester of the second year of the B University of Education. and taking courses in 'elementary Science Textbook Research 1' For the classes applying discussion-based science class, the analysis was made on 2015 revised curriculum, and 12th process-centered performance assessment based on discussion. The developed data had designed to develop concept of science achievement and science teaching efficacy. The study group applied process-centered performance assessment based on discussion science class, so unaffectedly study group could improve their concept of science achievement and science teaching efficacy. B University of education is singleness class that doesn't have compare group, so this study is constituted only study group. Applying based-discussion science class to study group, before and after concept of science concept test, science teaching efficacy test is performed. The results of the study were as follows. First, the study group applied discussion-based science class had statistically significant differences in concept of science achievement (p<.05). Second, the study group applied discussion-based science class had statistically significant differences in science teaching efficacy(p<.05). Third, after discussion-based science class of pre-service teachers have a very good feeling. Through such study results, the study could figure out that the class applying discussion-based science class has positive effect on concept of science achievement and science teaching efficacy.

The purpose of this study is to investigate the perception on video material making and the effect on science teaching ability after conducting non-face-to-face teaching material making activity for elementary pre-service teachers. This activity consisted two processes. One is that elementary pre-service teachers conduct inquiry, understand related science concepts, analyze science textbooks and then make video material. The other is that they watch video materials produced by colleagues. This study was conducted on 89 elementary pre-service teachers for 8 weeks. After this activity was completed, the perception on video material making and the effect on science teaching ability of elementary pre-service teachers were investigated, and the results were analyzed. In the process of making and watching non-face-to-face teaching materials, elementary pre-service teachers showed positive results in teaching-learning, video production, and emotion and attitude toward video material making. In addition, it was found that they improved their science teaching ability through this activity and were very satisfied with this activity. However, they also mentioned several disappointments such as exclusion of learners' right to self-determination, lack of various communication channels, and errors in content of materials. This suggests that if these problems are solved, non-face-to-face classes can also be a good form of class.
