  • This study is to ascertain pre-service teachers' conceptions for the causes of season change, to verify their conceptional mistakes, and to analyze how their conceptions are changed while presenting Disproof-Experiment Model where they cannot explain it with their current conceptions. 32 junior students of Education universities, pre-service elementary teachers, located at the middle of Korea participated in this research including two interviews and one experiment activity. As a result of analyzing of the data, the pre-service teachers held diverse conceptions for the causes of season change such as to mistake the phenomena, the distance between the earth and the sun, the tilting of the rotation axis and the revolving around the sun while changing the tilting direction of the rotation axis as the cause. After applying Disproof-Experiment Model designed by the researchers in order to change the current conception above, the conception changes of the pre-service teachers were investigated. Diverse Disproof-Experiment Models were used differently depending on the pre-service teachers' conceptions. As a result of the application of Disproof-Experiment Model, 26 out of 28 pre-service teachers were changed to scientific conceptions. It was determined that in order to modify pre-service teachers' conceptions, designing and presenting the Disproof-Experiment Model appropriate to their conceptions are effective after analyzing their conceptions. In case of conceptions that pre-service teachers feel difficult, it was established that unraveling experiment models prescribed after investigating the preconceptions and identifying the misconceptions are important.

  • This study aimed to investigate how middle school teachers perceived major features of the 'Free Learning Semester'. In 2013, the Free Learning Semester has been proposed by Korean government to provide students with the educational programs which deals with various activities in classroom in order to increase student's learning ability. The Free Learning Semester helps students to figure out their dreams and develops their talents. The government plans to expand the Free Learning Semester to all middle schools by 2016. Since teacher's perception is an important matter in the application of the Free Learning Semester, this study seeks to document the changes in curriculum by observing the perception of teachers in the school that implemented the Free Learning Semesters and those that did not implemented the Free Learning Semesters. 172 teachers from nine middle schools in Busan that their school schedules allowed were surveyed. Two school which operated the Free Learning Semester were compared to seven schools which did not operate the Free Learning Semester. The results are summarized as follows: First, almost all (97.7%) teachers in the Free Learning Semester schools have completed a training whereas 74.6% of the teachers in the non-Free Learning Semester schools have not. The usefulness of the training was satisfactory, but the teachers in the Free Learning Semester Schools wanted more practical help with the curriculum. Second, the result, which was statistically significant(p<.05), revealed that the first grade second semester of middle school was the best time to implement the Free Learning Semester. In order for its successful establishment in schools, there needs to be a reliable and effective evaluation system. However, the results regarding the introduction and management of the new system were not statistically significant. Lastly, in the Free Learning Semester Schools, the changes in teachers' perception were statistically significant (p<.05). The results show that the teachers need the training and the teacher's community to implement the curriculum and set a basis for valuation.

  • The purpose of this study was to analyze the professionalism of elementary school teachers and to draw out factors which elementary teachers should try to improve their professionalism for environmental education. For the study, both Quantitative analysis and qualitative methodologies were applied: First, randomly selected 483 elementary teachers from Seoul and Gyeonggi self responded to 5 evaluation areas by Hungerford et al. (1994) to evaluate their environmental education professionalism through the use of five point Likert scale. Second, 2 elementary teachers' environmental classes were observed for the purpose of analyzing strengths and weaknesses in classroom instruction, and then the results of self-evaluation on environmental education professionalism and teacher professionalism as shown in the classes were compared. It was found that 483 elementary teachers including 2 teachers fer analyzing classroom instruction who performed a self-evaluation gave themselves mid-scores on the Hungerford et al.'s 5 evaluation areas. However, the result of self-evaluation did not correspond with the result of actual class observation and teacher interview. That is, the actual environmental classes conducted by 2 teachers did not seemed to reflect the evaluation areas which were the foundation of the study: the conceptual awareness, the investigation & evaluation, environmental action skills, and educational application. The results of this study can be used as the basis reference to develop teaching-learning program and in-service programs for professional development of teachers for successful application of environmental education in elementary school classes.

  • This study examines teachers' implementation of strategies to modify the aggressive behavior of students with intellectual disabilities in Saudi Arabia, to determine the obstacles to their real-world execution. In addition, it presents potential approaches to overcome the obstacles to implementing strategies with this group of students. The research employed a qualitative design using semi-structured interviews as a data collection tool and applied a thematic analysis. The study population comprised 35 teachers of students with intellectual disabilities and the study sample numbered six teachers. The interviews were conducted via different methods: three by phone, two face-to face, and one using the Zoom platform. The results revealed inadequate understanding among teachers of intellectual disability and behaviour modification strategies, and this affected their capacity to develop plans that were compatible with the needs of students with intellectual disability. The findings also identified multiple obstacles that impede teachers' implementation of strategies to modify aggressive behaviour among students with intellectual disabilities; the most important being the lack of input from a psychological specialist when developing programs to modify aggressive behaviour. In general, it is apparent that programs for modifying aggressive behaviour are neither structured nor complementary, due to the scarcity of administrators with sufficient knowledge and familiarity with the characteristics and personalities of students with intellectual disabilities. This study presents several recommendations, the most important of which is that teachers of students with intellectual disability should develop themselves through training courses to enable them to deal with these students and create treatment plans that include strategies and clear steps to modify the aggressive behaviour of students with intellectual disabilities. To support teachers, it is also necessary to remove the obstacles facing education centres by providing financial support to create an environment in which they can access the required devices and equipment in their classes.

  • The purpose of this study was to confirm how the students have responded to their class according to STEB (science teaching efficacy belief) of secondary science teacher in astronomy classes. Middle school teachers in charge of 'The Solar System' and 'The Exosphere and Space Development' in the 2009 Revision Science Curriculum content system is selected as an object of study through random sampling method. Twenty-nine teachers were taken STEB questionnaire and asked to make it out. Twenty-seven completed a questionnaire of them is selected for this study. In addition, the top and bottom 5% selected through frequency analysis with the total score from the questionnaire were regarded as high and low STEB teachers. For data collection, this study was used methods such as semi-structured interviews, recording, participant observation. The results were as follows: First, science teachers of high STEB had a high accessibility about excellent professional knowledge and content of the curriculum relating to astronomical field. Second, high STEB teachers were prepared by the appropriate teaching strategies adequate to student-centered learning, whereas the low STEB teachers totally have had teacher-centered learning. Third, high STEB teachers had been provided as the idea that you can take advantage of a variety of instruments, as well as scientific knowledge through the Astronomical Society. Therefore, confidence in astronomical class and teaching strategies through content of the curriculum were very important variables to predict the STEB as well as astronomy-related class activities such as astronomical observations.

  • The premise of the study is that teacher communities or teacher interest groups are one of the representative examples of Communities of Practice (CoP) formed by teachers who engage in the process of collective learning regarding science teaching. Based on the theory of CoP, we investigated and interpreted the process of identity development of six science teachers who have been actively involved in teacher communities. We conducted 2-3 individual interviews with the teachers in order to explore their narratives and personal experiences of being involved in the communities over the years. Results indicated that a teacher community is a place where the teachers not only generated and shared repertories of ideas, documents on teaching and learning, or routines (i.e. practices), but also formulated a set of relationships through social participation. Teacher communities actively provide the teachers a sense of joint enterprise and identity, and where the teachers have an opportunity to develop themselves personally and professionally as science teachers playing major roles in their communities.

  • This study investigated the content and the effect of peer discussion about classroom practices on their science teaching. Participants included three science teachers with chemistry backgrounds in middle and high schools. Each of them had their classes videotaped and observed the footage as well as discussed the lessons together. The teachers had six meetings on 15 recorded lessons including one meeting beforehand. Teachers' discussions were also audio-taped and the data was transcribed. Teachers extensively discussed their lessons not only in terms of instructional strategies and scientific concepts but also the curriculum organization and teaching goals. Analysis of video-recorded lessons showed that instructional strategies were changed partially, but the aspects of curriculum organization in relation to teaching goals were not changed. Analysis of the recorded data revealed that teachers recognized the problems in their science teaching and considered the practical alternative ideas suggested by peers, but teachers proposed the necessity of experience to practice in their class. The study shows that observing and discussing each other's classes is one possible way to improve the class. Implications about teaching improvement for other teachers were discussed.

  • In this study, we surveyed the 68 teachers from eight science high school and four science academy for the gifted through questionnaires about research ethics education and ethical research environment in Korea. First, we examined the current state of research ethics education. Half of the responding schools included research ethics education in their curriculum. Although only half of the schools have this in their curriculum, more than half of the total number of teachers surveyed personally taught research ethics in class, and almost 90% of the teachers said they taught the research ethics during students' research activity. However, 63.24% of teachers said that research ethics education was not enough still. Second, we investigated the ethical research environment. In terms of knowledge and experience, the teachers were competent, and they were creating an environment that enabled peers and self-verification. However, research ethics, regulations and verification systems are not well equipped in schools. Since the principals are highly interested in research ethics education, there seems to be enough improvement on the ethical research environment. Finally, teachers said that additional research ethics education, change in student attitude, development and continuous maintenance of the verification system, encouragement to develop ethical environment, and clear guidelines were needed for ethical research of students. The result of this research will be able to provide the following. First, it will help set up a direction for research ethics education at every gifted school. Second, it will provide insights on how schools and teachers can create an ethical research environment for the students of science-gifted students.
