The purpose of this study was to analyze the science inquiry problem finding ability of gifted elementary students of science and general elementary students. For this purpose, this study analyzed the types of science inquiry problems in an ill-structured problem finding situation. Also, this study has compared science inquiry problem finding abilities of those two groups. From the results of this study, new ways of improving student' science inquiry problem finding ability and selection of gifted students of science were suggested. The results of this study can be summarized as follows. First, most of the inquiry problems generated by the scientifically gifted and the general students in an ill-structured problem situation could be categorized into seven types (measurement, method, cause, possibility, what, comparison, relationship) according to the inquiry objectives, and both group found more problems in scientific context than in everyday context. Regardless of the context of problem, scientifically gifted students found more problems and the type of problems generated by them were more various than those of general students. Second, there were differences in problem finding ability between scientifically gifted and general students. Scientifically gifted students found more problems and the quality of problems were higher than general students.

The purpose of this study was to investigate and analyze the elementary teachers' views and students' views about the difficulties in teaching and learning on open inquiry activities of elementary school science. Semi-structured interviews were conducted individually with three elementary teachers who have serviced more than three years, and with twenty four elementary students attending schools located in Cheongju City. And their anecdotes were collected and analyzed. The interview questions were developed through Seidman's steps to acquire the reliability in the interview data. From the interviews and anecdotes, we found that elementary teachers' views about the difficulties of teaching open inquiry activities: the difficulties of teaching in finding inquiry problem and planning inquiry, the difficulties of managing group activities, the difficulties of managing class hours for inquiry, the lack of the students' inquiry abilities, and problems on students' affective characteristics. And the students have the views about the difficulties in doing open inquiry activities: the difficulties of finding inquiry problem and planning inquiry, being unaccustomed to write reports, the troubles with investigating, problems on affective characteristics, the difficulties of joining in a group, and the lack of inquiry abilities. The teachers give suggestions for effective application of the open inquiry activities: first, the teachers must encourage students' emotion and will in doing open inquiry activities, second, there must be the steady inquiry teaching and learning in ordinary elementary science classes. Based on the results, this study suggested that elementary teachers should concern specially about students' being unaccustomed to write reports and the troubles in doing scientific investigation.

Even after learning electric current, elementary school students have various non-scientific conceptions and difficulties. Because flow of charge is not visible. Also elementary school students do not learn theory but phenomena, so they cannot transfer theoretical perspective to new situation. In this research, we have designed instruction based on PhET simulation visualizing flow of electric charge and applied it to 37 science-gifted students in elementary school for measuring conceptual understanding. As a result, six out of the seven Hake gains of question set are high gain and just one is middle gain because the students have understood the flow pattern of the charge through circuit elements such as light bulbs, wire, as well as battery with PhET simulation and it gives a chance to create various questions spontaneously about electric current. Also they become able to do spontaneous mental simulation without PhET simulation about flow of charges. This research, suggest that developed materials using PhET simulation could be used as not only program for gifted students in elementary school, but also the electrical circuit section in an elementary science curriculum.

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 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.

Elementary teachers should lower their levels of expectation and indeed perspectives to those of elementary students. Even in relation to basic symbols, such as an arrow, can be read differently by teachers or students. Semiotics deals with the creation of meaning in rotation to symbols and signs. This study introduces semiotic analysis to the study of science textbooks. Elementary science textbooks contain a great many inscriptions, such as photographs and cartoons, even more than texts, such as words and sentences. Inscriptions employ various social conventions such as arrows, auxiliary lines, etc. Some conventional signs, however, hold different or indeed multiple meanings than the textbook author intended the sign to have. The arrows used in science textbook, mainly in the inscriptions, were analyzed and classified according to their intended meaning. The results indicated that teachers should use such arrows more carefully in lessons with elementary students.
