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.

The purpose of this study was to investigate how extracurricular science club activities affect sciencerelated attitudes of female elementary school students. The experimental group was organised with thirty female elementary school students selected from a school in a small city and two schools in a town at Jeju special selfgoverning province. The students were encouraged to participate in a variety of scientific experiences and inquiry activities for ten months. The control group consisted of another thirty girl students chosen from the same schools. The pre-test and post-test on science-related attitudes were administered to both the experimental and control groups. The result of this study shows that meaningful changes have been observed in science-related attitudes of the experimental group, whereas the control group reveals no meaningful changes. Science-related attitudes have been analyzed in three categories such as cognition, interests, scientific attitude. The experimental group shows meaningful changes in all of the three categories, while the control group shows no change in any category. When the female students from small city and those from the town were separated, the result shows that the latter shows more positive changes in science-related attitudes through science club activities than the former.

This study examined the implications of a place-based earth science program integrated with Mathematics. 11 pre-service earth science teachers and 22 middle school students participated in the service education activities of earth science for 30 hours focusing on the measurement of the earth's size through earth science experiments as part of the middle school curriculum. In order to minimize errors that may occur during the earth's size measurement experiments using Eratosthenes's shadows length method of the ancient Greek era, the actual data were collected after triangulation ratios were conducted in the locations of two middle schools: one in remote metropolitan and the other in rural area. The two schools' students shared the final estimate result. Through this process, they learned the mathematical method to express the actual data effectively. Participants, experienced the importance and difficulty of the repetitive and accurate data acquisition process, and also discussed the causes of errors included in the final results. It implies that a Place-Based Earth Science Program activity can contribute to students' increased-understanding of the characteristics of earth science inquiry and to developing their problem solving skills, thinking ability, and communication skills as well, which are commonly emphasized in science and mathematics in the 2015 reunion curriculum. It is expected that a place-based science program can provide a foundation for developing an integrated curriculum of mathematics and science.

In order to investigate the trends in science education research using AR (Augmented Reality) and derive implications for elementary science education, we analyzed 71 research articles on AR application in science education published in both Korea and abroad from 2010 to August 2020. In quantitative aspects, the number of published articles has steadily increased. For domestic researches, the number of papers targeting for elementary school students was higher than that of middle & high school students. In the research method aspects, qualitative methods were most frequently used. In particular, papers regarding the development of AR program and verification of its effectiveness were most frequently published. The researches using mixed method in domestic field were smaller in number than that of the research in abroad. There were similar trends in research targeting elementary school students. In the aspects of the contents, more researches were performed on biology and earth science areas than others. In case of researches for elementary school students, the proportion of researches on biology and earth science was even higher. Domestically the proportion of studies on the convergence of science and non-science subjects was higher than that of foreign studies. The number of researches exploring the effectiveness on 'non-scientific attitude domain', 'cognitive domain', and 'program domain' were relatively higher than that on 'inquiry & practice domain' and 'science-related attitude domain'. For types of AR contents, 'observation manipulation type' was mostly studied, followed by 'experimental activity type', and 'learning guide type'. In case of studies on elementary school students, the ratio of 'observation manipulation type' contents was higher than that of others, whereas studies on 'field problem solving type' were relatively less reported than others. In addition, studies on 'simple interaction' were most frequently reported. Particularly, there were relatively few studies on 'linear and nonlinear interactions' in domestic field. As a result of analyzing key words, we found that the key words related to the characteristics and implementation of AR frequently occurred, and the key words related to elementary education and the merits of AR had many direct connections with other key words.

The purpose of this study is to categorize specific factors and characteristics of positive science experience by qualitatively analyzing the positive science experience cases in the memories of pre-service elementary school teachers. For this purpose, 101 essays written by pre-service teachers on the theme of 'my enjoyable science class experience' were analyzed. The collected data were analyzed using an inductive analysis method, and as a result, the characteristics of positive science experience cases in the memories of pre-service teachers were categorized into 4 categories and 12 topic groups. Specifically, 'experience of exploratory activities using special materials', such as long-term raising and observation of animals and plants, experiments using edible materials, and using special experimental tools had a positive effect on scientific experience. In addition, 'experience of activities emphasizing scientific inquiry' such as emphasizing observation activities, experiments accompanied by clear experimental results, making activities, and using various materials also had a positive effect on science experience. In addition, 'student-centered activity experience' such as strengthening student autonomy, emphasizing collaboration between students, and performing science activities outside of the curriculum also had a positive influence on the science experience. Lastly, 'positive influence of teachers', such as teachers' encouragement and enthusiasm, helped to positively recognize science.

I looked into hypochondria, an increasing social problem, in psychological and Korean medical aspects and these conclusions were made through 16 clinical cases based on HyungSang medicine. Hypochondria is a disorder that is caused when feeble minded person could not fight the reality. It is caused by deficiency and stagnation of Ki which connects body and mind. In Korean medical view point mind and body is the same. Particularly, in HyungSang medicine believes that everyone's way of life and how to deal with situation differs according to the characteristics and traits. HyungSang medical treatment in hypochondria Mind and body is in line with each other, so manifestation of mental activity is caused by deficiency of combining action of vital Ki. Medication that helps combining force of vital Ki is needed. As the way people handle situation is different, according to characteristics and trait it is valid to differ counselling and treatment according to the criteria. Looking at 16 case studies of hypochondria patients, in gender wise, woman with astriction quality and engaging in much mental activities are more vulnerable. In view of vital substances, more cases were found in Jung type and Ki type. In animal type, bird and reptile type were, and in six meridian type, Tae yang, Yang Myong, Tae Eum and Kwolum type were more susceptible. Especially, cases of Indang being stagnant was noticeable. Moreover, the pulse activated parallel with the Heart which is a leading organ that manifests mental activity and controls seven emotions, so many cases were found that was far from Heart-Small intestine and Heart-Gall Bladder relationship.

In this study, pre-service science teachers' reflective thinking in their journal writing was investigated. To do this, the authors used pre-service science teachers' journal writing abilities, wherein they not only reported data and result formally, but also wrote their feelings and reflections about an inquiry-based physics experiment they performed. Pre-service science teachers' writings were decomposed into sentences and each sentence was analyzed into a framework with 4 dimensions: knowledge, procedure, orientation and attitude. Reflective thinking in knowledge dimension included reflection on what they know before the experiment, what they still do not know and what they learned from the experiment. Reflective thinking in procedure dimension included recalls of experiences about general experimental procedures and specific experimental skill. Reflective thinking in orientation dimension included their views about the nature of science and science teaching and learning, and reflective thinking in attitude dimension consisted of interests, motives and values about the experiment they performed. While there were some variations in frequency distribution of reflective thinking by the topic of experiments, pre-service science teachers' reflective thinking in journal writings revealed their metacognition on their knowledge and learning, epistemological belief about science and science learning, and affective domain related to experiment. This study can infer that such kind of writing with 'their own language' in an informal way followed by formal 'scientific' reports in a scientific experiment has a significance not only as a mediator representing reflective thinking but also as an instructional activity to facilitate reflective thinking in science learning and teaching.

Recently, there has been a dramatic increase in the number of cases that have formed and operated teachers' learning communities through cross-curricular consulting at the school level. The purpose of this study is to explore cross-curricular instructional consulting as an activity of teachers' learning communities at the school level, and investigate the effect of cross-curricular instructional consulting on middle school science teaching. We analyzed features and limitations of cross-curricular instructional consulting revealed in three case studies in middle school, including open classes and instructional consulting sessions, and conducted additional instructional consulting on the same videotaped science classes with science experts from outside. According to the results, science inquiry experiments are often replaced with text reading and interpreting, students' misconceptions and exact scientific representations are ignored, and the goal setting as well as class coverage has been questionable and disputable in science classes resulted from cross-curricular instructional consulting. Discussed in the conclusion are the necessity of cross-curricular instructional consulting in middle school, and ways to overcome limitations of the method of cross-curricular instructional consulting, including alternatives to a praise-only policy in cross-curricular instructional consulting, ways to use cross-curricular instructional consulting without compromising the subject's essence, and ways to improve the undue authority of consultants.

The TIMSS assessment is conducted every four years, and Korean fourth grade cohort in TIMSS 2011 participated in TIMSS 2015 again as eighth graders, which produced the first achievement data of the cohort group of elementary and middle schools. In this study, in order to investigate the causes of the decline in Korean students' science achievement with grade changes from the fourth to the eighth grade, we analyzed educational context variables such as characteristics of students, teachers, and classroom instructions of the top 5 achievement countries participated in both TIMSS 2011 and TIMSS 2015. According to the results, students' sense of school belonging increased, whereas students' positive attitudes toward science teaching decreased with the grade change from the fourth to the eighth. As for the teacher characteristics, the teacher's professional development activity increased, and the teacher's confidence in science teaching showed similar tendency to the international average. Regarding classroom instruction characteristics, the frequency of inquiry-related science activities was highest at the fourth grade, and lower than the international average at the eighth grade. Based the results, we suggested implications for science teaching and learning as well as further studies including development of differentiated strategy by the school level to improve students' achievement, the necessity of converting into more student-engaging science classes, and the necessity of in-depth study on the teacher related educational contextual variables.
