The purpose of this study was to analyze the elementary students' selection of representable value and confident method that appear in measuring activities by using a microgenetic method. The participants were seven elementary students in the fourth grade. They performed the same measuring activities six times for the study period. Data were collected by interview and observation with their activity recording papers and video tape transcription. Their activities were recorded and documented for the analysis. Results were as follows. First, in the time measuring activity, elementary students developed desirably as their measuring experience increased, for example they selected a representable value in use of a repeated measurement and used a various method in the domain of a time measurement and they showed an increase of a quantitative observation in the volume domain except in the length domain. Second, in a confident method of a representable value, though they must rely upon a repeated measurement, they only measure repeatedly in the time domain. Also in the time domain, it doesn't get accomplished a exact confidence of a representable value at a shortage of skill about a measurement. Accordingly this study will be implications for teachers to teach a handling abilities of measuring instruments to elementary students and to be promote understanding a nature of measurement.

This study attempts to explore the nature of science anxiety experienced by science-gifted middle school students based on Giorgi's phenomenological research method. Among the first-year middle school students selected by the University-affiliated Science Education Institute for the Gifted, six science-gifted students with high levels of science trait anxiety and science state anxiety experience were selected. Two interviews related to experience of science anxiety were conducted with participants. As a result of the analysis, science anxiety experienced by science-gifted students was caused by setting the ideal self-concept, lack of confidence, past experiences, difficulty in contents, and something valuable. Students complained of physical·physiological, cognitive, emotional·psychological discomfort when they felt science anxiety, and recognized it as an opportunity for growth. In addition, science-gifted students were shown to cope with various ways such as confronting uneasy situations directly or refining their minds to overcome various uncomfortable symptoms that arise when science anxiety is triggered. Some students thought that no special efforts were required to lower their level of anxiety because anxiety was relieved over time. The students had both negative and positive meanings for science anxiety. The results of this study will help teachers in-depth understanding of middle school science-gifted students who experience science anxiety and provide a theoretical basis for what kind of educational environment should be created and educational programs should be provided in relation to science anxiety.

The purpose of this study was to investigate beginning science teachers' perceptions of inquiry-based science instruction using open-ended questionnaire and semi-structured interview. Participants of this study voluntarily set up a goal of inquiry-based science instruction, planned inquiry-based science lessons, and shared and reflected their teaching experiences in their professional learning community for more than a year. Participant teachers recognized students' construction of core scientific concepts through performing scientific inquiry as a goal of science inquiry instruction. Participant teachers indicated that goals of science education such as 'learning scientific core concepts', 'improving students' interest of science', 'improving scientific thinking', and 'understanding the nature of science' can be achieved through students' active engagement in scientific inquiry. Participant teachers recognized not only the importance of teachers' role, but also what roles science teachers should play in order to enable students to perform scientific inquiry. Participant teachers emphasized teachers' roles such as 'identifying core concepts', 'reorganizing science curriculum', 'considering student ability', 'asking questions and providing feedbacks to students', 'explaining scientific concepts', and 'leading students' argumentation.'

Researches on laboratory work show that students often achieve little meaningful learning through laboratory work. One reason for this failure is that students often do not know the different types of laboratory work and the 'purposes' of them. Therefore, this study investigated middle school student' ideas about the purposes of laboratory work. To seventh grade students(n=147) of middle school in Seoul, Korea, we asked (Question 1) "Why do scientists do laboratory work?" and (Question 2) "Why do you do laboratory work in science classes?" It was required a short essay including the reasons and examples of them. From the results, it was found that 56.8% of the students had ideas that scientists do laboratory work for discovering new facts or inventing something, and 82.9% of the students responded that they do laboratory work for understanding and memorizing the contents of science textbook. In addition, the differences according to gender and to school achievement level, and the relationship between the ideas about scientists' laboratory work and about school science laboratory work were examined. The results showed that boys responded 'social usefulness' more frequently than girl, while girls mentioned 'personal pleasure' more frequently than boys in relation to the purposes of scientists' laboratory work(p<.05). According to the achievement level, it was founded that 'middle' level students replied 'to remember' more frequently than high and low levels in relation to school science laboratory work. Finally, students who had ideas that scientists do laboratory work for verifying a theory had the similar ideas about school science laboratory work. In conclusion, students are lack of diverse and proper views about laboratory work. It is recommended that teacher need to make clear the purpose of laboratory work and help students to understand of it.

This study explored the possibility of introducing modern physics into the elementary school science curriculum. The study discussed the need of introducing modern physics to elementary school students and examined the results of certain projects and studies on teaching modern physics to elementary school students. Furthermore, this study proposes several teaching and learning techniques to introduce modern physics into the elementary school science curriculum. Modern physics can be linked to various everyday situations experienced by students and can increase their interest and curiosity in science. Additionally, introducing modern physics to elementary school students who are yet to establish a background on the classical view of nature can help them build a new perspective. Recently, several global projects to introduce modern physics at the elementary level have also reported positive results regarding the increase in student understanding and interest in modern physics. The study briefly proposed specific topics and teaching and learning techniques that could be suitable for the elementary school level. These proposals are expected to advance discussions on the possibility of introducing modern physics. However, appropriate follow-up studies are warranted to confirm the possibility and effectiveness of this initiative.

In liberal SW education, nurturing student with creative problem-solving ability based on SW is considered important. The purpose of this study is to design SW education and to investigate the effects on students' computational thinking and creative problem solving abilities. This study designed classes in accordance with convergent project and the CT-CPS model and 38 undergraduate students have participated this study. The questionnaire survey was given to students and analyzed the effectiveness of class. The results of this study were as follows: Fitst, SW education significantly improved computational thinking and creative problem solving ability. Second, computational thinking improve significantly in high and low initial score group and creative problem solving improve significantly in low initial score group. However, creative problem solving ability did not improve significantly in high initial score group. Third, computational thinking improve significantly in all majors and creative problem solving improve significantly in college of natural science. However, creative problem solving ability did not improve significantly in college of humanities and social science. In examining the effects on students' computational thinking and creative problem-solving abilities and verify differences by pre-test and major, this study provides significance in expanding the understanding about the nature liberal SW education.

Purpose: This study was conducted to examine understanding of the meaning of well-dying and types of such views held by medical practitioners and nursing students. Methods: The Q-methodology was used to analyze the subjectivity of each item. The P-sample was made up of 22 medical practitioners or nursing students. The P-sample was instructed to rate 33 statements using a 7-point scale to obtain forced normal distribution. They were asked to make extra comments on the statements that were placed on both ends of the distribution curve. The PC-QUANL Program was used for the factor analysis of the collected data. Results: The participants had three types of meaning of well-dying. Total variance explained by these types was 57.97%" where type 1 was "reality-oriented", type 2 "relationship-oriented" and type 3 "obeying-the-nature". Conclusion: The participants' subjective views on well-dying influences their medical practice on patients who are facing death. Therefore, medical practitioners should have profound insights concerning life and death. To that end, a training program is needed to help medical practitioners develop a proper view on well-dying by subjectivity type.

The purpose of this study is to explore students' epistemic goals and considerations in designing an experiment task and to investigate how a shift in the students' epistemology affected their argumentation. Four 7th grade students were selected as a focus group. According to the results, when they designed their own experiment, their epistemic goal was 'scientific sense-making' and their epistemic considerations - the perception of the nature of the knowledge product was 'this experiment should explain how something happened', the perception of the justification was 'we need to use our interpretation of the data' and the perception of the audience was 'constructor' - contributed to designing their experiment actively. When students tried to select one argument, their epistemic goal shifted to 'winning a debate', showing 'my experiment is better than the others' with the perception of the audience, 'competitor'. Consequently, students only deprecated the limits of different experiment so that they did not explore the meaning of each experiment design deeply. Eventually, student A's experiment design was selected due to time restrictions. When they elaborated upon their result, their epistemic goal shifted to 'scientific sensemaking', reviewing 'how this experiment design is scientifically valid' through scientific justification - we need justification to make members accept it - acting as 'cooperator'. Consequently, all members engaged in a productive argumentation that led to the development of the group result. This study lays the foundation for future work on understanding students' epistemic goals and considerations to prompt productive argumentation in science classrooms.
