General education is changed by accepting the change in education environment to digital generation, emphasis about student-centered education, and change of teacher's role. E-learning has taken center stage as an effective learning environment but the problems are drawn for the absence of interaction that is important in learning. In this study, on the basis of questionnaire results about learning using website, we operated blended-learning where students come and go in cyberspace and physical space to set up the lesson environment for emphasizing interaction. We selected a control group (N=40) and an experimental group (N=40) from second grade students in a middle school for this research. General instructor-led lessons were implemented in the control group and blended-learning lessons to emphasize interaction between teacher and students were implemented in the experimental group. The experiments were applied to eight class-hours in 'characteristics of matter' unit. We implemented Test of Science Related Attitude (TOSRA) to the students before and after the lessons and administered questionnaire for checking attitude changes and perception in students. The results of the test show that the experimental group students were more encouraged and became more confident and curious about scientific learning than the control group students. The analysis of the interview and results of TOSRA show that blended-learning provided guidance and feedback by the teacher to the experimental group students more than the control group students. Blended-learning is suggested as a learning-method that is helpful in improving scientific attitude in students because it enables them to express their experiences without limit of time-space and promote interaction between teacher and students.

The purpose of this study is to examined the relationship between child care teachers' science teaching efficacy and children's scientific attitude. Then, using the instructional creativity as a parameter to increase the quality of teacher-children interaction, we examined how the teacher-children relationship changed. In this study, 303 child care center teachers in Suwon, Gyeeonggi were surveyed. To analyze the data, structural equation modeling and Sobel-test were performed using SPSS 23.0 and AMOS 23.0. The analysis results showed that child care center teachers' science teaching efficacy had positive effects on the teachers' creativity and the children's scientific attitude. Furthermore, the creativity of child care center teachers had a positive effect on children's scientific attitude. The result of the Sobel-test revealed that child care center teachers's creativity played a mediating role between teachers' science teaching efficacy and children's scientific attitude and acted as a key variable in promoting children's scientific attitude. In conclusion, it has been identified that the creativity of the infant teacher's teaching is an important change that has a positive effect on the child's scientific attitude. Therefore, if education is provided to enhance the creativity of the professor when the infant teacher is working as a science professor at the same time, it can contribute to the quality of the child's scientific attitude.

This study aimed to identify the difficulties that new science teachers in secondary schools experience. Subjects for this study were 190 science teachers attending qualifying training for 1st degree of teaching certificate. Using an open questionnaire, the difficulties these teachers encounter were collected, categorized, and compared between their first year and their succeeding years of teaching in terms of their school level, gender, majors and regions. Results showed that first year science teachers have had difficulties in areas including subject teaching, guidance, administrative affairs, human relationship and self-understanding. On their succeeding years, difficulties about subject teaching were reduced to half while other difficulties remained. New teachers in middle schools have experienced the most number of difficulties about guidance, while new teachers in general high schools have experienced the most number of difficulties about subject teaching. Based on these findings, some recommendations were proposed for new science teachers in secondary schools, school administrators, and training institutions.

The purpose of this study is to investigate secondary science teacher's concepts of good science teaching. To do these, I have developed a questionnaire composed of 32 good teachings on education content, instructional method, instructional environment and atmosphere and assessment categories. 136 secondary science teachers have participated in the questionnaire and were requested to show agreement. Additionally, they were requested to describe the best science teachings that they have experienced. Results are as follows: First, the best science teaching that science teachers thought is a teaching that is in full accord with students' level in education content category, a teaching with an energetic interaction in instructional method category, a teaching in a trustful atmosphere in instructional environment and atmosphere category, a teaching in which students could learn something through a teaching-related assessment in assessment category. Second, secondary science teachers thought that a self-directed learning, a differentiated instruction and a teaching with diverse materials are not important factors in good science teaching. Third, there is a difference between good teaching that secondary science teachers have conceived and good teaching that they have experienced. It shows that science teachers did not precisely understand what good science teaching is. Additionally, I discussed the need of finding a case on good science teachings and a support of an interaction-focused teaching.

This study aimed to explore elementary teachers' beliefs about science teaching, science learning and the nature of science and consistency among these beliefs. Data was collected by using an open questionnaire and semi-structured individual interview. Teachers' beliefs were classified as traditional beliefs and constructivist beliefs. Traditional beliefs were further divided into content knowledge-centered beliefs and procedural knowledge-centered beliefs. The result showed that a relatively large number of teachers among the total 30 teachers had traditional beliefs about science teaching, science learning, and the nature of science(respectively 60.0%, 66.7%, 83.3%). Most of traditional beliefs were identified as content knowledge-centered beliefs. The proportion of teachers with consistent beliefs for all three aspects was 40.0%, the proportion of those with consistent beliefs for two of them (those with related beliefs) was 53.3%, the proportion of those with different beliefs for them (those with divergent belief) was 6.7%. Most of the teachers with the consistent beliefs had the content knowledge-centered beliefs of traditional beliefs. Although constructivism has been widely emphasized in science education from the 1980's, the rate of the teachers with the consistent beliefs in constructivism was as low as 6.7%.

The purpose of this study is to confirm secondary biology teachers' recognition about cell and gene concepts that should be taught in biology according to each school level and to classify the concepts into essential, optional and non-essential ones. We developed a questionnaire in consultation with 5 biology professors after selecting some biological concepts from some data about the recommendations of BSCS, biology, study for the connection with biological contents in each school level. This survey was conducted to biological teachers in secondary schools (146 individuals) from all over Korea for studying the concepts of the cell and gene in elementary and secondary schools. The results of this study revealed the following: The number of essential concepts in the cell and gene domain increases as the school levels go up. Moreover, secondary biology teacher recognized that there must be much more cell and gene concepts that should be taught in elementary and secondary schools compared to those suggested in the science curriculum and BSCS' recommendation.

This study assumes that recognition about scientific creativity may differ according to teacher, students and parents, and that this difference can affect the actual teaching, encouragement, and development of scientific creativity. Based on teacher's free responses and literature reviews about features of scientific creativity, we extracted 16 items describing contrary views about scientific creativity. Using these 16 items, we obtain responses from 652 students, teachers, soon-to-be-teachers (college of education students) and parents about whether they agree with each item or not. Results show that 1/4 of the participants agreed with the views contrary to the views accepted in literature. And we found out which views contrary to the accepted views in literature were agreed upon by participants, and that which items divided the groups for having contrary views. From these results, we discuss the possible effects of participants' recognition on teaching, encouragement and development of scientific creativity, and suggest so further studies.

The purpose of this study was to investigate the relationships between the pedagogical content knowledge in science teaching of pre-service early childhood teachers and their attitude toward science and science teaching efficacy belief. A total of 294 pre-service early childhood teachers responded to a questionnaire that examined their pedagogical content knowledge in science teaching, attitude toward science, and science teaching efficacy belief. The results of this study were as follows: First, teachers had average pedagogical content knowledge in science teaching. The groups of 3rd and 4th grades were significantly higher than the 2nd grade group. Second, the teachers' recognition was below average in attitude toward science and science teaching efficacy belief. The groups of 3rd and 4th grades were significantly higher than the 2nd grade group. Third, a meaningful statistical relationship was found between the pedagogical content knowledge in science teaching of pre-service early childhood teachers and their attitude toward science and science teaching efficacy belief. As the score of pre-service early childhood teachers in pedagogical content knowledge in science teaching became higher, the score in attitude toward science and science teaching efficacy belief became higher.

The goal of the study was to examine pre-service teachers' emotional experiences, especially during student teaching. The following questions guided this study. First, during student teaching, what are the characteristics of emotional experiences of pre-service science teachers? Second, what are used as the emotional rules and strategies by student teacher? In this study, we tracked nine pre-service science teachers over a four-week period of the student teaching. The data sources were lesson observations, interviews, emotional journals, and video-recorded classroom lessons. Results showed that student teachers experienced various 25 different types of emotions which were reported as the primary emotions of Koreans. The main subjects for interaction for positive emotions were students. For negative emotions, students, teachers and student teachers themselves all resulted in such negative emotional experiences. When the student teachers experienced negative emotions, they followed the emotional rule that their emotions should not be expressed in front of the students. Because of this, they tried various strategies for controlling emotions, such as 'understanding students', 'finding the positive side', 'seeing good students', 'ignoring', 'holding back', 'evading', and 'giving up'. Finally, suggestions for teacher education were discussed.

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.
