This study investigated pre-service elementary teachers' understanding of the planetary revolution movement of Mars and their explanatory models to show how the Sun-Earth-Mars system worked. An assessment item set using five celestial maps drawn from the Stellarium was designed to probe pre-service teachers' understanding of the prograde-retrograde motion of Mars. Among 23 participants, only four showed scientifically accurate understanding of Mars movement and drawing correct explanatory models for the planetary movement. Even the pre-service teachers who construed correctly prograde and retrograde motions of Mars showed a clockwise movement model due to their intuitive perceptions of Mars movement data from the celestial maps. Pre-service teachers with poor understanding of planetary movement also showed weak explanatory models due to their limited observation or lower spatial thinking. Although the planetary motion is not an easy topic for pre-service elementary teachers, it can be argued if the alternative approach, such as using appropriate observational data of a planet and changing the frames of reference between Earth-based view and Space-based view, is employed effectively in teaching planetary motion, pre-service teachers can reach the upper level of leaning planetary motion in terms of the planet's revolution.

In this study, find out of recognition of the effect of science, society and ethical aspects on natural disasters and understanding degree of knowledge applying for SSI class aimed at elementary pre-service teachers by developing SSI training program of the 'Earth and Space' field. Also, after SSI class application we examined the change perceptions of elementary pre-service teachers. SSI training program was that elementary pre-service teachers participated in the SSI class of a variety of subjects in the field of 'Earth and Space' and directly joined in the decision-making process and reflectional discussion with colleagues as conducted in this class reflective discussion with the pre-primary teachers pre-service teachers. Elementary pre-service teachers were understanding of the nature of the science and to understand in more depth about the SSI class characteristics. This study, second grade 115 people who was taking 'science and teaching materials' course in B National University of Education at B city participated. In order to apply for SSI class, one semester based on 15 weeks until seven weeks were science and teaching materials and based on the nature of science, after 8 weeks we set the theme of the contents related to the Earth and space and give lesson applied for SSI. During 8 weeks, test subjects 4 classes were taking 50 minutes a week 100 minutes. First time has theoretical lessons in topics related to the 'Earth and space' and on the second week, each classes participate in the decision-making processes respectivly by dicussing and debating on the first week's topic as regarding social and moral aspects of it. We obtained the following results. First, elementary pre-service teachers were acquiring the results of 67% in the knowledge aspects of the 'Earth and space'. This result was determined that most of the elementary pre-service teachers were liberal arts in high school. Second, while participating in the SSI class, elementary pre-service teachers were concretely aware of the nature of SSI and the characteristics of the class. Third, the elementary pre-service teacher are thaught that introduction education courses about 'Earth and space' are needed but most of the students responded that this would require a lot of effort of teachers. This was derived from not familiar class form that did not fulfill in the science teaching methods until now.

The purpose of this study is to identify the basic scientific knowledge of in- and pre-service elementary school teachers, specific areas having insufficient knowledge and the reason for the lack of understanding. For the study, we analyzed the survey asking basic scientific knowledge to in-service elementary school teachers within an urban communities and pre-service elementary school teachers enrolling the first, the second and the third year in National University of Education. The results shows that there is the lack of understanding about scientific knowledge such as boiling points, perihelion, substances, and elements, which elementary school teachers should have exactly known. With regard to the age, an effort is required to increase scientific knowledge of the in-service teachers in 50's, compared to those in 20s' and 30s'. In the pre-service teachers, the average in the third year was significantly higher than that in the first and second year. Regarding the major background in high school, both of in- and pre-service teachers who completed the science course showed significantly higher average than those who completed the liberal arts course. In addition, regarding the major in the university, the average of the group with science and engineering major was higher than that of the group with other majors.

The purpose of this work is to investigate pre-service elementary teachers' belief in science gifted education. To do that, from September to November 2012, this research had been conducted with 42 students who were in the third year of P University of Education. The conclusions of this work are presented as follows: First, the pre-service elementary teachers considered exploration ability to be the most important talent for the gifted students in science, and chose task commitment as the next most important. They regarded intelligent ability and leadership ability as the relatively less important. Secondly, regarding the most important tool in choosing scientifically gifted students, the pre-service elementary teachers preferred creativity test. It was found that they considered the intelligence test and academic achievements, which require intelligent ability, to be the less important. Thirdly, regarding the special knowledge related to science gifted education, the pre-service elementary teachers considered pedagogical knowledge about the gifted to be the most important. Fourthly, regarding a class type for gifted students in science, the pre-service elementary teachers most preferred project learning. Project learning is a learning method in which students choose an interesting problem and solve the problem in cooperation with group members. It is the most widely used exploration class in gifted education. It is in the same context as the result that exploration ability is the most important factor to elementary gifted students in science. This work revealed that, with regard to a talent for the gifted in science, judgment of the gifted in science and science gifted education, the potential ability and affective ability of gifted students are considered to be more important than their intelligent ability. Therefore, it was analyzed that pre-service elementary teachers' belief in the gifted students in science is almost consistent with the recent trend of gifted education.

The focus of this study was to identify and describe environmental preconceptions held by pre-service elementary teachers about three issues : greenhouse effect, ozone layer depletion and acid rain. Two hundred and twenty nine pre-service elementary teachers participated in this study. A 36 question survey was created by one of the authors. The questions focused on the cause, effects, and interactions of three environmental issues greenhouse effect of one layer depletion and acid rain. Pre-service elementary teachers answered the questions on a Likert scale. An analysis of the survey data indicated that the majority of pre-service elementary teachers possess an array of incorrect conceptions about the causes and effects of the greenhouse effect ozone layer depletion, and acid rain. and also many pre-service elementary teachers thought that there were causal relationships among the increase in greenhouse effect, the destruction of ozone layer, and the increase of acid rain.

For teachers' conceptions and understandings are critical to their decision making and classroom practice, this study attempts to understand pre-service elementary teachers' views and practices of science inquiry during peer teaching practice. Fifteen 4th year university students in teacher education program participated in peer teaching practice. Their teaching and reflective discussion were video and audio recorded and written lesson plans were collected for data analysis. Five science teacher educators individually looked into the data and shared their comments and interpretations on pre-service teachers' views and practice. The study findings suggest that pre-service teachers emphasized the importance of providing students with motivating resources in the beginning of lesson, employing certain inquiry teaching models, the process of predicting and dis/proving via experiment, and teachers' minimal intervention as the important features of inquiry teaching. Science teacher educators emphasized that it is critical to help children understand inquiry questions in the beginning of inquiry process, to be mindful of children's problem solving and critical thinking rather than following instruction models or simply going through prediction and test process. They also commented that teachers' guidance could lead a good inquiry process in classroom practice, not always interfering students' inquiry. Based on the findings, the study suggests science teacher educators need to understand what and how pre-service teachers view and practice science inquiry teaching and consider these as useful resources where they can start effective teaching for pre-service teachers at the university level.

The purpose of this study was to explore the impact of scientific inquiry-based peer teaching experience on pre-service elementary teachers' science teaching efficacy, anxiety to science and attitude toward science. The participants of this study included 118 pre-service teachers. The pre-post paired t-test design was implemented to examine the effect of this program. In addition, the semi-structured interviews were carried out for investigating their changes of affective characteristics. The result of this study showed that inquiry-based peer teaching provided pre-service teachers with the opportunities to enhance their science teaching efficacy and attitude toward science and reduce their anxiety to science. The findings imply that it is possible to meaningfully change elementary teachers' affective characteristics when effective strategies are adequately adopted.
