The purpose of this study is to analyze the errors and difficulties which pre-service secondary teachers shows during the task modification in consideration of the cognitive demand and to provide significant implications to the pre-service teacher education program related to the modification of the mathematical tasks. In the pursuit of this purpose, tasks were selected from perpendicular bisector units and 24 pre-service teachers were asked to modify the tasks to higher and lower level tasks. After the modification activities, opportunities for reflection and modification were provided. The findings from analysis are as follows. Pre-service teachers had a difficulty to distinguish between PNC tasks and PWC tasks. Also, We identified the interference phenomena that pre-service teachers depended on the apparent elements of the task. Pre-service teachers showed a tendency to overlook the learning objectives and learning hierarchy during the task modification, and to focus on some types of task modification. However, pre-service teachers were able to have meaningful learning opportunities and extend the category of tools to technology including Geogebra through self-reflection and correction activities on task modification. The above results were summed up and we presented the implications to the task modification program in the pre-service secondary teacher education.
The purpose of this study was to investigate pre-service biology teachers' perception of the evolution. This study was to compare the views of pre-service biology teachers with no religion with those of christian preservice teachers. Subjects were 77 pre-service biology teachers who enrolled in an university and graduate school of education located in Seoul. The instrument of this study was a questionnaire which consisted of 14 items on 2 domains: the nature of science, the origins of human beings. The key results are as follows. Most pre-service teachers showed highly understanding of the characteristics of science. However pre-service biology teachers still possessed naive views on the distinction of law and theory. In terms of the methods of science, many of the pre-service biology teachers considered scientific theories to progress through the accumulation of observation and experiments or through changes and modifications in existing theories. Compared with the pre-service teachers with no religion, christian pre-service teachers had conflicting views and misconceptions about the origins of human beings. The factors of religion were found to be one of the important barriers which prevent them from understanding the origins of human beings. The results suggested that the education program for pre-service biology teachers integrating the concepts and development process of the scientific knowledges should be effective for understanding the nature of science. For pre-service biology teachers, It is important to understand conflicting views of the christian pre-service teachers who understand creationism as a science.
The competence of teachers, comes out through their lesson, is one of the key factors of school education. The purpose of this study is comparing the viewpoints on the science lessons in the elementary classrooms between pre-service teachers and highly experienced teachers in order to draw implications on pre-service teacher educating system. The participants of the study are 14 junior students in a university of education and 9 elementary school teachers who are highly educated and have much career experience. Each student participant observed one video clip with science lesson of their classmate. The total number of the video subject to observation is 4. Meanwhile experienced teachers observed 1 or 2 videos which are the same to those the students watched. The participants made a class criticism according to the General Standards for Class Critique made by KICE. The in-depth analysis of the criticism yielded the following conclusions; First, pre-service teachers had narrow views on the science class mainly limited in the practical part of class, but experienced teachers had wide views covered to class-knowledge, plan, and practice. Second, most experienced teachers thought that learning is the process by which students acquire knowledge or concepts by themselves, and the main purpose of the class is to help students' learning. Meanwhile, there were many pre-service teachers who thought that conveying knowledge or concepts to students was the main purpose of the class. Third, experienced teachers thought that a good science class should maintain consistency around the learning goals from the planning, implementation, and evaluation. However, many pre-service teachers did not take the learning objectives so seriously.

The purpose of this study was to investigate and analyze the effect of mathematics teaching experience during the teaching practicum on pre-service elementary teachers' beliefs about mathematics. The conclusions drawn from the entire research were, as follow: First, it can be said that mathematics teaching experience during the teaching practicum has a significant effect on the change of pre-service elementary teachers' beliefs about mathematics. Specifically, the teaching experience during the teaching practicum has statistically significantly negative effects(p=.05) on pre-service elementary teachers' beliefs about the teaching mathematics. Second, the factors which help pre-service elementary teachers the most in preparing for mathematics classes are collaborating teachers in charge of supervising them, the teacher's guidebook and materials acquired from the Internet. Third, pre-service elementary teachers are well aware of the importance of understanding students and emphasize concrete manipulative activities, but experience lots of failures due to difficulty of drawing students' attention. Fourth, collaborating teachers do not play a significant role in helping pre-service elementary teachers develop and change their beliefs about mathematics positively. The advise given by collaborating teachers to pre-service elementary teachers is mostly about simple techniques of managing the classroom. So, collaborating teachers do not affect significantly and positively on the change of pre-service elementary teachers' beliefs. Fifth, regardless of their belief tendency, pre-service elementary teachers teach more confidently and feel more satisfactory when they prepared for classes more thoughtfully and understanded students more deeply.
In this study, pre-service science teachers' difficulties in teaching practice were investigated from the perspectives of pre-service teachers and cooperating teachers. Nine pre-service teachers who were attending a department of chemistry education at a college of education in Seoul and participated in teaching practice, and two of their cooperating teachers participated in the study. Teaching practice were observed, documentary data were collected, and interviews were conducted. The collected data were analyzed using analysis method of grounded theory. As results of the analysis, the pre-service teachers had difficulties in preparing and executing lessons which include experiments, because education related to experiments in middle and high schools was insufficient at the college of education and environments of cooperating school were unfamiliar to them. They had difficulties in encountering various responses from students in student-centered activities and tried to control students. Cooperating teachers did not provide specific assistance to ensure the autonomy of pre-service teachers, so that pre-service teachers suffered. Guiding science club activities was a meaningful experience to pre-service teachers, but it was a burden on both pre-service teachers and cooperating teachers. Educational implications of these findings were discussed.
In this study, we surveyed characteristics of the science related collaborative problem solving competency of pre-service elementary teachers, especially required in the digital age. The participants in online survey were 119 pre-service elementary teachers of National University of Education located in Gangwon province. The analyzed results of survey were as follows: First, pre-service teachers performed their task responsibly in collaborative problem solving context related to science. However, they lacked competencies in making rubrics for problem solving processes or outcomes, and setting up rules about team activities. Second, in using ICT technology, the competencies of utilizing tools such as app and software lacked compared with the competencies of searching data in online and using ppt. Third, there was no statistically significant difference among groups by their intensive major in university or selective subject in high school. Nevertheless, pre-service teachers majoring in natural science showed more persistence than those majoring in humanities in problem solving context. Finally, there was no significant gender difference except 'clear communication and accomplishment'. That is, female pre-service teachers performed more responsible in their task and showed more fluency in communication and presentation within their group than male counterparts. Based on these results, implications in the field of pre-service teacher education were discussed.
The purpose of this study was to analyze characteristics of environmental awareness and environmental worldviews on environmental UCCs which made by 27 pre-service biology teachers, and relationship between environmental awareness and environmental worldviews of them. Environmental worldviews were divided into planetary management worldview, stewardship worldview and environmental wisdom worldview. As for theme fo environmental UCCs, most of pre-service teachers chose themes such as environmental destruction, environmental protection, environmental conservation and coexistence with human and environment. Themes of environmental UCCs were somewhat different between females and males. Female pre-service teachers preferred UCC themes related to human's daily life as a consumer but males preferred to environmental protection. Many pre-service teachers referred that major cause of environmental problem was development of environment. Most of them had envionmental wisdom worldview, and tried to use fear appeal to express ways of solving of environmental problems and envieonmnetal worldviews. After making environmental UCCs, more pre-service teachers had envionmental wisdom worldview. This result implies that it is necessary to develop pre-service educational programs realted to environmental worldview formation.
The purpose of this study was to investigate the perspectives of pre-service elementary teachers on science education of future by using Draw-A-Science-Teacher-Test Checklist and open-ended questionnaire. The subjects of this study were 136 pre-service elementary teachers. The results of the research are as follows. The pre-service teachers thought that the physical environment reflecting the latest science and technology for science education will be developed in the future. However, few respondents indicated that student-centered equipment or a free and creative classroom environment would be provided. Second, they predicted that there would be changes in teacher's activities due to the introduction of advanced facilities and equipment, but most of the other teachers' activities were thought to be similar to those of current teachers. Third, the pre-service elementary teachers thought that a variety of new technologies would be used in science education and science teachers would mainly teach high-technology, IT technology, science knowledge, and newly discovered science concepts. In addition, we found that pre-service elementary teachers' images were more 'teacher-centered' than 'student-centered'. These results show that pre-service elementary teachers are expected to utilize the latest science and technology actively in science education in 2030 and that it will lead to changes in the physical environment, teachers' activities, education contents, and teaching and learning methods. In addition, they viewed acquisition of science concept as an important goal of science education in the future and had different points of view from the current science education curriculum and scholars' emphasis on educational research for the future.
