The purpose of this study was to examine Korean preservice science teachers' understanding of the nature of science (NOS). Thirty-one Korean preservice teachers were given an open-ended questionnaire about their understanding of NOS. The Korean preservice teachers' responses were categorized according to pattern and theme. These findings will provide information to aid in the development of curriculum and instruction to improve preservice teachers' understanding of NOS. Compared to in previous studies, Korean preservice teachers demonstrated various philosophical stances that have been suggested by philosophers of science. In addition, they were more likely to connect science to human endeavors and social needs. These results were interpreted in relation to the influence of the science methods course, secondary science curriculum, and the traditional cultural view.

The purpose of this study was to explore the perceptions of preservice teachers toward children from single parent families. 218 preservice teachers (209 female and 9 male) who were enrolled in the department of early childhood education and child care & education were participated in this study. A questionnaire was developed based on the questionnaire developed by Song, Sung, & Han (2003). Data were analyzed by using SPSS 11.5. The results were followed. First, preservice teachers' personal experiences of single parent families did not influence their perception of children from single-parent family. Second, preservice teachers who strongly held the view of keeping traditional family structure showed negative expectations of children's school adjustment. Third, preservice teachers reported the importance to help the children adjustment at school as well as to deal with their personal and family problem. The results presented that there was an increasing need in teacher education, to develop curriculum for preservice teachers to have balanced views or reduce their biased perception against diverse family structure and children from single parent families.

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.

The purpose of this research was to investigation of elementary preservice teachers' understanding of the image observed in a diverging lens. To achieve the research purpose, Scientific inquiry activity of 'Observing Objects through a Diverging Lens' in the 2009 Revised Science Curriculum was carried out by 29 junior elementary preservice teachers, and preservice teachers' difficulties were analyzed during scientific inquiry activity. The results were as follows. First, preservice teachers had difficulties in comparing the size of the images. Second, preservice teachers couldn't correctly explain the reason about the changing of the image size according to distance from the lens to the object. Third, preservice teachers couldn't correctly explain the changing of the image size according to distance from the lens to the eyes. Fourth, preservice teachers were classified into five levels according to their conceptions of the image formation by the diverging lens, and most of them stayed in the first level. The result of this research suggests that reformations in text and preservice teachers' education.

This study was to analyze the inquiry characteristics of preservice teachers as they classify trilobites. For the study, 70 preservice teachers attending teacher training university participated. The classification tasks used in the study were 9 photos of trilobite fossils. The preservice teachers' inquiry activity was to classify the evolutionary processes of trilobites after observing trilobite fossils by group and then to construct a phylogenetic tree. The results of the study are as follows. First, preservice teachers observed the external features of the trilobites and constructed systematic classification results based on their observed contents. Second, preservice teachers classified trilobites using various classification criteria. Third, the phylogenetic tree of preservice teachers and the phylogenetic tree of scientists were very similar. The preservice teachers constructed a sphylogenetic tree based on the observation and inference of the change from a simple form to a complex form, which is a general evolution process of the trilobite fossil claimed by scientists. These results suggest that group-based inquiry activities with sufficient time are very effective and that the experience of inquiry activities is very important for preservice teachers.

This qualitative study investigated two preservice teachers' conceptual ecologies in professional development during the science teacher preparation program. The notion of a conceptual ecology contains nature of knowledge, science and science teaching, learning, and content knowledge and comfort level. The data were collected during the participants' preservice year and their practicum experience. Both data collections and analyzing were from the various sources of interviews, teaching observations, journals, and information and profiles by the participants' supervisor. Two preservice teachers serve as cases representative of this study. Results show that problems preventing the preservice teachers from moving closer to conceptual change teaching were their understandings of the nature of science and the nature of knowledge. The preservice teachers' views about knowledge come from, and what knowledge is, are largely shaped by the nature of science and learning drive pedagogy and classroom practice. Knowledge of and comfort with the subject matter are also important.

This study examined inservice elementary teachers' thoughts on the development of educational apps by preservice elementary teachers and implications for TPACK education for preservice elementary teachers. A case study was conducted in which preservice elementary teachers developed a science education app, and the three teachers were surveyed for their thoughts regarding this. The results regarding the characteristics of the developed app by preservice teachers were as follows. First, "inquiry" had the highest value among educational goals intended by the preservice teachers. In addition, the scores for tool-type apps and apps in which interaction between learners and instructors occurs were relatively high. Second, most of the preservice teachers developed apps to meet curriculum goals, but their apps showed low-level characteristics in terms of the constructive and cooperative dimensions. The results of the analysis of the thinking of elementary school teachers regarding the education development apps are as follows. First, elementary school teachers assigned the lowest scores to the effectiveness of the apps, and to this problem, the achievement standard with respect to the curriculum and the evaluation and modification activities fir the apps were proposed. Second, the teachers indicated that it would be appropriate to provide the experience of making apps to directly improve the TPACK of preservice teachers. Third, the respondents thought that preservice teachers should develop block coding literacy to create apps using App Inventor. Fourth, the teachers considered it necessary to emphasize simulated instructions, as well as the experience of collecting and handling data through apps to improve preservice teachers' TPACK app development for educational use.
