Software integration becomes very important in these days. Since the 4th industrial revolution has begun and influences its heavy effects on our daily life, software education has been introduced in the 2015 national revised curriculum. The purpose of this study is to verify the effects of a mobile web application for the elementary algorithm class based on STEAM on the problem solving process of elementary school students. To do so, in this study we constructed an algorithm learning contents based on STEAM for new software education and developed a mobile web application for flipped learning to improve their problem solving ability. Further, an experimental group and a controlled group are selected respectively from the 5th grade elementary school students. Then, a new flipped learning class using our mobile materials was applied to the experimental group while a traditional lecture class using the activity papers was applied to the controlled group. Finally the paired samples t-tests were carried out. As a result, we found that there was a statistically significant difference in problem solving process between the two groups. Based on our experimental research and the results of statistical analysis, the mobile web application class based on STEAM turned out to be effective in improving the problem solving ability of elementary school students.

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 aim of this study is to raise a cognition and necessity of effective geoheritage education for pre-service teachers. We conducted a survey research of 190 elementary and secondary pre-service teachers in Chung-buk province, 2013. The survey showed that pre-service teachers did not recognize and explain geoheritatges well due to lack of education even though they have heard about 'geoheritages' through broadcast media. Although most pre-service teachers were not trained for geoheritage courses, some of them were educated from their elementary and middle school teachers. However, even the trained pre-service teachers have insufficient cognition for geoheritages, either. Some of pre-service teachers recognized the significance of geoheritages and responded to a necessity of geoheritage education. The pre-service teachers recognized that education for geoheritages is not included in present elementary and secondary curriculum, even though education of geoheritages by teachers at school would be the most effective approach. Furthermore, the pre-service teachers answered that elementary school curriculum should raise much curiosity and provide effective learning for geoheritage education even though negative views are present such that students may have to spend considerable time for geoheritage education. Finally, the pre-service teachers expect to experience with field activities for geoheritage education as a present curriculum, and responded that they would prefer video aids for education provided from professional geoheritage organization. As a result of this investigation we provide strategy for introducing to Pre-service teachers about value and preciousness of geoheritage.

Training SW talent can have a positive impact on social development by increasing the competitiveness of our society in the era of The 4th Industrial Revolution. In order to train SW talent, this study analyzed 436 students in 1st, 2nd, and 3rd grade at B High School in S-si, Gyeonggi-do, how SW education is perceived by students, and how the timing of SW education affects students' SW-related career orientation. This study shows that the expansion of SW education in public education was necessary and groups which got an SW education since elementary school have higher career orientation related to SW than other groups. As a result, it could be inferred that getting SW education at an early stage had a positive impact on students' career orientation. Studies will be needed to analyze how SW education in the early stages works specifically on SW-related career orientation.

In this study, we investigated the preservice elementary school teachers' self-images of science teaching and the factors influencing their formation by using Draw-A-Science-Teacher-Test Checklist (DASTT-C). One-hundred eighty-two sophomores and 183 seniors were selected from the departments of science and non-science education in three national universities of education. DASTT-C was administered to the sophomores at the beginning of the Spring Semester, and to the seniors at the beginning of the Fall Semester. Analyses of the results revealed that the self-images of science teaching of the seniors were more student-centered than those of the sophomores in the department of science education. However, there was no significant difference between the DASTT-C scores of the sophomores and the seniors in the department of non-science education. Many sophomores answered that the main factors affecting their self-images of science teaching were teaching-learning experiences in elementary, middle and high schools. However, many seniors cited the content and teaching methods in science education courses as well as direct or indirect teaching-learning experiences in teaching practices regardless of the departments. Educational implications of these findings are discussed.

A recent increase of interests on the influence of 3D printing and low prices of 3D printers makes a high possibility of 3D printer adoption as a educational equipment in public education settings. The Ministry of Science, ICT and Future Planning and Ministry of Trade, Industry and Energy proposed '3D printing industry development strategies', and had pilot schools to include understanding of 3D printing concepts and practices in the primary, secondary and high schools' curriculum. However, even if 3D printers were provided in educational settings, the research on educational content and methods to properly react to this change is very limited. Therefore, this study reviewed various 3D modeling software because a modeling skill is a prerequisite skill to use 3D printers, and proposed a creative design spiral based teaching content that can be incorporated in elementary school contexts.
