In this study, pre-service elementary teachers (n=68) participated in an inquiry of exploring children's science ideas as group work. After conducting interviews with children, the pre-service teachers analyzed their science ideas on specific concept and propose a teaching plan based on their findings. This paper aimed to find the positive learning experiences of the pre-service teachers by looking into their inquiry process. Questionnaire, researcher's journal, classroom videos and final reports were collected and analyzed for this multiple case study. Four representative groups were chosen and interviewed after submitting their final reports for in-depth understanding of their inquiry process. The positive learning experiences found in the process of their inquiry into children's science ideas were as follows: (1) exploring children's ideas have brought the opportunity for enhancing pre-service teachers' science content knowledge. (2) the pre-service teachers developed their ability in creating questions that probe into children's understanding. (3) the pre-service teachers recognized that children have various incomplete and unstable science ideas. (4) the pre-service teachers could suggest teaching strategy based on their findings.

The purposes of the present study were to identify the stages of early concept development of the air in young Korean children and to compare the stages with those reported by Piaget. The subjects were 87 four, five, and six-year-old children from one kindergarten, two day care centers, and an elementary school, all located in Seoul. To collect the children's ideas of the air, individual interviews were conducted based on Piaget's Clinical Interview method. According to the results, the children formulated very unique concepts of the air, showing artificialism, anthropocentric finalism, animism, and dualism. Their concepts of the air showed a consistent developmental process which is very similar to the stages proposed by Piaget. This implies that young children's misconcepts and idosyncratic ideas are very natural and can not be eliminate easily by artificial instruction. This also means that children's internal ideas themselves should be the starting point of education.

During the last decade researchers in science education and psychology have emphasized the importance of children's ideas, or "what they already know", which they bring to their related learning situations. Most research reports on the children's prior ideas reject both the traditional epistemologies and the conventional learning theories. Therefore, this study has its objective to analyze the traditional epistemologies as well as post-positivism contemporarily in vogue, to examine both the conventional learning theories and the constructivism of psychology, and then, based on the analyses, to draw the implications for the future science education. The implications are described under such headings as the nature of science, the science curricula, and the science teaching/learning. The implications are drawn in logical relation to the post-positivism and constructivism, and some of which are empirically validated by the research on the children's conceptions.

The purposes of this study were to investigate children's preconception about matter, to analyze children's conceptual change. of ,matter by science learning activities, and to investigate understanding possibility about mallet The subjects of this study were the second grade students of an elementary school and science learning activities were conducted to 2 boys and 3 girls for investigating their conceptual change. Video tape recording, interview, drawing pictures and writing statements were used to collect data. The concepts in this study were properties of matter, states of matter, uses of matter and origins and changes in matter. Then, the collected data were analyzed by the way of categorization and qualitative method. The conclusions of this study are as follows: science loaming activities were effective for changing misconceptions of matter to scientific concepts. Conceptual changes of high achievers happened easier and more than of low achievers. In the ideas about matter, some children had supernatural ideas and animism, which were most second grade students' characteristics.

The purpose of this study was to investigate and analyze the conception of elementary school students on evaporation and condensation, and then to verify the types of the conception. Forty-eight children from six elementary schools were sampled by stratified random sampling in Seoul and other provinces. They responded to the questionaire and the interview. This study was carried out according to the process of the basic study, the preliminary study, and the main study. The materials collected were classified and analyzed according to the types of children's ideas. The findings of this study were as follows. 1. The vocabulary used to describe the evaporation phenomena varied according to the situations, and the scientific term "evaporation" was more frequently used by the older groups. 2. Most children answered that the last location of water were air/sky/cloud. Air/cloud which represents the scientific conception of the location of water were mentioned by children of all ages. The higher the grade of the children were, the more scientific conception the children mentioned, however. 3. Most children referred to the heat as the factor of evaporation. Wind, on the other hand was mentioned by less than 10% of lower graders, and by about 30% of higher graders. 4. The result of asking children whether they thought it was possible to get the evaporated water back showed that about 70% of lower graders denied the possibility of the water being reversible. About 60% of higher graders. however, recognized that the water will be returned as rain or condensation. This increase may be associated with formal teaching of water cycle. 5. In the ideas of evaporation and condensation, some of the children have supernatural ideas and animism, which are most younger chilren's characteristics.

The aim of this research was to compare and analyze the children's ideas on evaporation and condensation between pre- and post-intervention. Forty-eight children from six elementary schools in Seoul and Kyung Ki provinces were sampled by stratified random sampling. A set of structured activities was then provided which allow children to explore evaporation and condensation phenomena. All of these activities had a preliminary phase which required the child to predict or speculate on evaporation and condensation using their existing knowledge. These structured activities on evaporation and condensation were reviewed by three professors and eigth primary school teachers. Their comments were used to revise the original contents of the structured activities. The data analysed were gathered by the questionaire and the interview. Pre- and post-intervention data related to evaporation and condensation were collected by the same teacher, and analysed into the same category scheme. Data coding was carried out several times by the researcher to ensure reliablity. Data collected were then classified and analyzed according to the types of children's ideas. The findings of this study were as follows: Results of this study showed that the the vocabulary used to describe the evaporation phenomena varied according to the context, and the scientific term "evaporated" was more frequently used by the older children after post-intervention. But everyday terms such as"dried up","disappered", "gone up" were also used by children as much as the level of pre-intervention. Scientific conception on the location of evaporated water, the factor of evaporation, the ideas about getting the water back and assumption about the physical state of the missing water has been increased for the most of the children after intervention. It was found that the intervention using was effective SPACE strategies regardless of the grade level of the children.

There is no doubt that science -and, therefore, science education- is central to the lives of all (NGSS, 2013). This manuscript focuses on ideas in astronomy that are at the foundation of elementary students' understanding of the discipline: the apparent motion of the sun explaining the day / night cycle on Earth. According to prior research demonstrating that neither children nor adults hold a scientific understanding of the big ideas of astronomy (NRC, 1996), understanding of concepts may base students' progress towards more advanced understanding in the domain of astronomy. We have analyzed the logic of the domain and synthesized prior research assessing children's spatial representation from an earth- and a space based perspective to develop a set of learning trajectories that describe how students' initial ideas about apparent celestial motion as they take school science can be build upon. In this study elementary students' representations were compared by their resident context including urban and rural. This study may present a first look at the use of a learning progression framework in analyzing the structure of astronomy education. We discuss how this work may eventually lead towards the development and empirical testing of how children learn to describe and explain apparent patterns of celestial motion.

Ability of understanding students' ideas and thinking is critical to teachers' professional growth. In this study, 'pedagogical reasoning' was conceptualized as teachers' reasoning ability of students' misconceptions and possible causes of misconceptions when they hear and observe students' science discourses. To investigate elementary pre-service teachers' pedagogical reasoning levels, children's science discourses on light reflection and electric circuit were video recorded and 43 pre-service elementary teachers were asked to identify children's misconceptions and possible causes of misconceptions after watching the video clips. In conclusion, pedagogical reasoning levels of pre-service elementary teachers were not high enough, showing significant difference in light reflection and electric circuit. Possible explanations of this difference and educational implications were discussed.

This study aimed to discuss the utilization of a makerspace regarding 3D printers in a children's library by conducting co-design sessions targeting the end-users, children. To achieve this, a program utilizing a 3D printer was conducted for seven children at the Seoul Children's Library, followed by interviews with both the children and their parents. The results revealed several key findings: First, during the design sessions, participating children showed interest in the physical realization of ideas through the use of a 3D printer. Researchers adjusted their level of intervention based on each child's tendency, playing a supportive role. Second, children became aware of various limitations associated with 3D printers and public library makerspace. Third, the rapport between children and researchers positively influenced the design sessions, driven by the active communication of children. This study suggests a reevaluation of the value and necessity of library makerspace from the perspective of user autonomy and creativity and emphasizes the need to closely understand the end user's requirements in establishing operational strategies for library makerspace.
