The purpose of this study was to investigate elementary school teachers' conceptions on the general remarks (GR) in the new science teacher's guide, the teachers' conceptions on inservice training program of the GR, and their opinions of improvement on the GR. Also, the teachers' utilization of the GR was examined. The participants were 152 elementary school teachers who were teaching grade 3~6. A questionnaire was used to collect data. The results of this study are as follows; First, at least 13.2~17.1% of the teachers did not have specific conception of the purpose of the GR, and more than 90% of the teachers expressed that the GR is necessary in the teachers' guide. Second, about 60% of the teachers responded that the training program on the GR is necessary, and when the program is open, their most favorite agency and speaker were a provincial education office and a textbook developer(or author), respectively. Their most favorite time and period of the training program were the vacation and 15~30 hours, respectively. Third, the mean values on the frequency of use were lower than 3 point of the five-point Likert scale at both the GR for grade 3~4 and the GR for grade 5~6, and the teachers' main use of the GR was the planning a science lesson for an open class. Fourth, the teachers suggested various opinions and there was difference between the opinions about the GR for grade 3~4 and the opinions about the GR for grade 5~6.

The purpose of this study is to investigate how elementary teachers perceive and practice using Visual Thinking (VT) in science classes. For this, we collected 161 VT teaching materials for science that uploaded on the elementary teacher's online communities, and analyzed the characteristics. Also we interviewed four elementary teachers who have used VT in science class. The results are as follows. First, VT teaching materials shared in teacher's online communities were most often used to review the science concepts that students learned. Most of the materials required 'remember' among the Cognitive Process, and most of them provided layouts for VT activities. Second, the participants were using VT materials to review the science concepts they learned, so that students remember them. Third, the participants were satisfied because of the beliefs of effects as follows: facilitating learning and reviewing what students had learned; increasing students' positive reactions and confidence; learning through the interation among learners; the formation of habits thinking visually; indirect experiences of science class; possibility of class corresponding to learner characteristics. Fourth, the participants had difficulties in preparing for the VT science class, such as the burden of making VT materials, the long preparation time, concerns over overlapping contents, consideration of learners' VT skills, and the themselves' drawing ability. Furthermore, they also had difficulties in proceeding for the class, like different preference among learners about Visualization and loss of objectives in science class using VT. Fifth, the participants needed support as follows: platform to share students' VT results; VT case books and teachers' guidebooks; physical environment.

The purpose of this study is to identify the effect of Teacher Participation-oriented Education Program (TPEP) for Elementary School Teachers to Improve Class Expertise in Science Classes with a focus on visual attention. The participants were two elementary school teachers in Seoul and taught science subjects. The lesson topic applied to this study were 'Structure and Function of Our Body' in the second semester of fifth grade and 'Volcano and Earthquake' in the second semester of fourth grade. The mobile eye tracker SMI's ETG 2w, which is a binocular tracking system was used in this study. In this study, the actual practice time, participant's visual attention, visual intake time average, and visual intake time average were analyzed by class phase. The results of the study are as follows. First, as a result of analyzing the actual class execution time, the actual class execution time was almost in line with the lesson plan after the TPEP application. Second, visual attention in the areas related to teaching and learning activities was high after applying TPEP. Factors affecting the progress of the class and cognitive burdens were identified quantitatively and objectively through visual attention. Third, as a result of analyzing the visual intake time average of participants, there was a statistically significant difference in all classes. Fourth, as a result of analyzing the visual intake time average of participants, the results were statistically significant in the introduction(video), activity 1, activity 2, and activity 3 stages in the lecture type class. The Teacher Participation-oriented Education Program (TPEP) for Elementary School Teachers to Improve Class Expertise in Science Classes can extend elementary science class expertise such as self-class analysis, eye tracking, linguistic, gesture, and class design beyond traditional class analysis and consulting.

The purpose of this study is to investigate the structural relationship between pedagogical content knowledge (PCK), grit, and teaching efficacy perceived by elementary school science teachers. Based on the results of the literature review, PCK was divided into knowledge domain and enactment domain, and these two domains were set as exogenous latent variables to investigate the structural relationship between PCK and teaching efficacy. In addition, teachers' grit was added to the structural equation model as an exogenous latent variable to investigate the effect of teachers' knowledge, enactment, and grit on teaching efficacy. Upon confirming the structural relationship between PCK and teaching efficacy, it was found that a high correlation between knowledge and enactment, and that knowledge had a greater effect on teaching efficacy than enactment. Furthermore, upon confirming the structural relationship between PCK, grit, and teaching efficacy, both knowledge and grit were found to have a statistically significant effect on teaching efficacy, while the relationship between enactment and teaching efficacy was not statistically significant. Based on the results of these studies, we discussed ways to strengthen teacher expertise and teaching efficacy in elementary school science classes and the meaning of grit in the field of teacher expertise.

This study compared the characteristics of an experiment f or determining whether gas occupies space presented in elementary school science textbooks to examine the validity of the experiment, identify and improve problems in its presentation, and verify its effectiveness. This study interviewed third-year elementary school teachers who had experience teaching this experiment to students. Based on teachers' opinions and observations, this study identified issues with the current experiment, developed an improved experiment, and determined its effectiveness. Through this analysis, three key findings emerged. First, the study found that the original experiment on gases was presented in the same or highly similar manner in 5 of 7 textbooks (71.4%). Thus, while various textbooks have been developed with the aim of promoting diversity and creativity in scientific literature, most experiments presented in these books are identical. Second, the existing experiment was not suitable for its target audience (third-year elementary school students) and was difficult to observe directly. The interviewed teachers also deemed the validity of the experiment to be considerably low. Finally, the original experiment was improved; this improved version was determined to be highly valid, showing a statistically significant difference compared with the original experiment. The improved experiment was effective for students as it involved activities suitable for their intellectual level and was directly observable through the senses. Thus, the study analyzed and improved an existing science experiment f or elementary students, providing insights into the 2022 revised science authorized textbooks and implications for future textbook development.

This study carried a survey to investigate teacher's cognition on preference and actuality about science laboratory and class environment targeting 262 science teachers. The results of this study are as follow: First, the actuality cognition of science teachers on science laboratory and class environment was lower than preference (p<.05). Second, there were no differences between preference and actuality regardless of gender (p<.05). However, the cognition on all of subordinates of preference appeared higher in females than males (p<.05). Third, at all levels of schools, preference is higher than actuality for science laboratory and teaching environment (p<.05). In case of preference, all of the subordinates indicated the difference between elementary and high school teachers (p<.05). On the other hand, in actuality there was a difference between elementary and middle school teachers in 'science laboratory facilities condition' domain only (p<.05). Fourth, the preference was higher than actuality in all school locations (p<.05). And in case of preference, there was no difference in all subordinates regardless of school sites. Whereas the cognition of small-medium city teachers was lower than metropolitan in actuality on the three domains of 'science laboratory facilities condition,' 'teaching condition and service support,' and 'staff policy and practice' (p<.05). As a result, this study informs that upgrading is necessary to achieve inquiry activity in science class in overall teaching environment including science classroom and laboratory.

This study aims to explore patterns and characteristics of coordination between evidence and theories which were found in pre-service elementary teachers' writing for their science inquiry. Five science inquiry activities and a total of 115 writings of the participant teacher at the elementary teacher preparation university in Korea were collected and analyzed for this study. Based on the writing analyses there were found four types of coordination between the evidence and theory. We proposed four types as: Type 1-Consistency of evidence and theory; Type 2-Consistence of evidence and theory including more extension or elaboration of theory; Type 3-Inconsistence of evidence and theory Type 4-Inconsistence of evidence and theory followed by coordination of them. Firstly the findings indicated that the most to least frequent types were Type 1, Type 3, Type 2, and Type 4. The most frequent type was Type 1. It is interpreted that theory in the inquiry questions were frequently figured out by participants and they selected supporting evidence out of data found. There were rarely found relations between activity topics and frequencies of coordination types except in activity 1. The findings in this study will connect to the point of how students collaborate their previously owned knowledge with experiment planning, data analysis and interpretation and making of their own scientific claims.
