The purposes of this research are to analyze preservice elementary teachers' degree of difficulty in classes of seasonal variation and suggest the measures of classes so that preservice elementary teachers can progress classes of seasonal variation effectively. To achieve them, the research was conducted for 90 first graders completing teaching method of elementary science in P university of education from Sep. to Dec. 2012. This research was conducted, based on the results of in-depth interview for 9 preservice elementary teachers who performed classes of seasonal variation, survey on the degree of class difficulty and evaluation of classes on 8 classes theme of Earth sector in elementary science. The results of this research are as follows. The first, preservice elementary teachers had relatively high class difficulty for teaching seasonal variation among the sector of the earth in elementary science. The second, in the evaluation of preservice elementary teachers' classes, the more the subject showed high class difficulty, the more the score of class evaluation was low. The reason is analyzed that high class difficulty reduces teacher's confidence. The third, preservice elementary teachers had insufficient knowledges and concepts which are basically necessary for the classes of seasonal variation. Especially, it was more serious for preservice elementary teachers who didn't learn Earth-science during their high school time. The fourth, it is necessery that concrete and systematical teaching method should be developed so as to improving preservice elementary teachers' teaching method for the classes of seasonal variation.

This study asked preservice elementary teachers to conduct an inquiry of observing the moon, and analyzed the phenomena observed, difficulties experienced, and pedagogical suggestions by the preservice teachers. Participants were 31 undergraduate students enrolled in a science course in a university of education. As a part of the course, the preservice teachers observed the moon for about a month and completed personal journals which described the phenomena they observed, difficulties they experienced, and the pedagogical suggestions to help elementary students conduct the same inquiry activity. The analysis of the journals revealed that the preservice teachers observed the moon mostly during the evening or night and that they noticed lunar phases, directions, altitudes, and color and brightness more frequently than other phenomena. The preservice teachers experienced difficulties related to the observation time, lunar phases, directions, and altitudes, and, reflecting on their own experiences, suggested a variety of pedagogical ideas about these difficulties. The pedagogical suggestions by the preservice teachers also included how to help elementary students keep their interest and perform the moon observation for a rather long period of time. Implications for moon investigations in the elementary school science classroom and relevant research were discussed.

In this study, we investigated elementary and preservice elementary school teachers' actual and preferred types of science assessment focusing on the purpose and the method of assessment. Participants were 75 elementary school teachers and 93 preservice elementary school teachers. The questionnaire adopted from previous relevant studies was administerd in order to examine the types of assessment which the teachers have actually implemented and the preferred types of assessment for hypothetical situations known as the prototypical examples of constructivist assessment. The results revealed that most teachers and preservice teachers tend to possess the summative-oriented purpose of assessment. An affective assessment purpose focused on evaluating students' interest, attitude, and curiosity toward science was newly identified in this study. In analyzing teachers' responses from the viewpoint of the method of science assessment, responses of an informal mode such as observation and portfolio were noticeable. However, most of them were found to correspond to the traditional summative-oriented purpose of assessment. For prototypical constuctivist assessment situations, teachers and preservice teachers were found to prefer the performance and the informal modes than the measurement mode of the assessment methods, whereas their purposes of the assessment were not found to be constructivist.

The purpose of this study was to examine preservice elementary teachers' understandings and instructional strategies about children's science misconceptions. The participants were sixty senior students from a national university of education located in the midwestern area of Korea. A questionnaire, developed on the basis of Gomez-Zwiep's semi-structured interview questions, was used. The results of this study are as follows: first, many of the preservice teachers showed appropriate understanding of 'definition of misconceptions' (96.67%), 'examples of misconceptions' (78.33%), 'resistance to change of misconceptions' (71.67%), and 'impact on instruction of misconceptions' (91.67%), except for 'sources of misconceptions' (45.00%); second, although almost all the preservice teachers (96.67%) appreciated the necessity of identifying children's misconceptions before instruction, 43.33% of the preservice teachers did not show appropriate understandings on when and how to identify children's misconceptions; third, most of the preservice teachers (81.67%) were generally aware of instructional strategies to address children's misconceptions.

Representation has been main topic in teaching and learning mathematics for a long time. Moreover, teachers' deficiency of representation about fraction results in teaching algorithms without conceptual understanding. So, this paper was conducted to investigate and analysize the elementary preservice mathematics teachers' representation about fraction. 38 elementary preservice mathematics teachers participated in this study. This study results showed that, the only model of a fraction that was familiar to the preservice teachers was the part of whole one. And research showed that, they solved the problems about fraction well using algorithms but seldom express the sentence which illustrates the meaning of the operation by a fraction. Specially, the division aspect of a fraction was not familiar nor readily accepted. It menas that preservice teachers are used to using algorithms without a conceptual understanding of the meaning of the operation by a fraction. This results give us some implications. Most of all, teaching programs in preservice mathematics teachers education have to devise to form a network among the concepts in relation to fraction. And we must emphasize how to teach and what to teach in preservice mathematics teachers education course. Finally, we have to invent the various materials which can be used to educate both preservice teachers and elementary school students. If we want to improve the mathematical ability of students, we will concentrate preservice teachers education.

In this study, we investigated preservice elementary school teachers' awareness of students' misconceptions about several science topics, and the variables influencing their awareness. Seniors (N=106) from an university of education were asked to predict elementary school students' misconceptions on science topics such as phase changes and dissolution. Their conceptions about teaching and learning were also measured. The results indicated that the preservice teachers' predictions about the kinds and/or the ratios of students' misconceptions were different from those reported in previous studies. The low level preservice teachers in terms of the degrees of possessing traditional conception about teaching and learning predicted more students' common misconceptions. The degrees of preservice teachers' constructivist conception about teaching and learning and their major, however, did not significantly influence the numbers of common misconceptions predicted.

This study examined the science learning environments experienced by Korean and U.S. preservice elementary science teachers during their 3-week clinical experience. Observational experiences of 97 Korean and 112 U.S preservice teachers were surveyed with an instrument that we developed for the study. Follow-up interviews provided a clearer picture of what preservice teachers observed and experienced in science classrooms during their clinical experiences. Korean preservice teachers experienced a variety of science teaching environments, whereas the U.S. preservice teachers reported limited opportunities to observe science teaching and learning in terms of 6 identified facets that we posed. Along with our interpretation of the contrast in findings, some of the challenges are discussed in providing preservice teachers with opportunities to observe, experience, and teach in effective science learning environments during the clinical experience.

The purpose of this study was to investigate inservice elementary teachers' view and the change of preservice elementary teachers' view on the nature of science by the science education course. The subjects were 386 junior preservice teachers in a National University of Education and 257 inservice teachers working in a metropolitan city. An instrument consisting of fifty eight items were developed on the bases of previous studies. Before entering the course, preservice teachers view was compared by gender with T-test and no significant differences were found except the category 'role of a scientist'. Preservice teachers view was also compared by major with ANOVA and significant differences were found on the categories 'scientific method' and 'scientific law'. After the course, on comparing their view by gender, significant differences were found on the categories 'scientific theory', 'scientific knowledge', and 'scientific law'. The result of ANOVA by major, significant differences were found except the category 'role of a scientist'. Inservice teachers view was compared by gender and major and the differences were no significant, the significant differences, however, were founded in comparing by career and ability.
