The goal of this study is to analyze and understand invention classes, student's experiences, and motivation to suggest a future direction for K-12 Maker Education in Makerspace. We collected qualitative data using open-ended survey from 100 Invention class students. Through data analysis, we could explore perceptions of students about their inventions and meaningful experiences when they used technologies for enhancing their idea and problem finding ability using interpretive approach. We found that the main themes are (1) Perception and motivation to join in the invention class courses, (2) Perception and the normal method of obtaining the idea on invention, (3) Finding new technology for enhancing of knowledge for the invention, and (4) Relevance of the learning experience and invention activities in Makerspace. As a result of this study, we found that the educational programs using technologies should focus on supporting implement of prototypes instead of helping students create their own ideas in Makerspace.

This study examines the change in students' science attitude and the growth of their core competencies through science classes emphasizing digital literacy. To this end, we conducted a study on 116 first graders in C middle school in the C region, and entered a science class that emphasized digital literacy of 35 classes. First, as a result of examining the effect on science attitude, a statistically significant change (p<.05) was observed. The effect size for each subregion ranged from 0.67 to 1.52. Second, there were no differences in the overall frequency of growth perception according to the type of class that emphasized digital literacy. However, in the analysis of core competencies, Web-based classes did not show a large difference in frequency by core competencies, whereas high-tech classes were slightly different by core competencies. This is an implication for science education, and it is necessary to increase the utilization of science classes that emphasize digital literacy.

In this study, a science writing heuristic class with emphasis on social interaction and tool improvement for 10 middle school students at the National University Science-Gifted Education Center in Jeollanamdo was conducted to investigate the perception of STS (science technology society) relationship and students' perception of the effects of class. After science writing heuristic class emphasizing social interaction and tool improvement, the students became aware of the STS relationships as follows: Science-gifted students have come to perceive that experimental tools and technology contribute to the development of scientific theory, that it is difficult to solve all social problems with only science and technology, and that science is a social interaction activity. In addition, science-gifted students responded that they became aware of the relevance of STS through intensive inquiry conducted on the same subject for several hours, communications with colleagues in another group through peer reviews, communication to solve problems with colleagues in the same group, activities to improve tools in the process of inquiry, inquiry using familiar materials and phenomena. In order for students to effectively recognize the relationship of STS in science-gifted class for middle school students, it is necessary to provide experience to solve problems using various experimental tools, experience to have trial and error in the process of solving inquiry problem under the same subject, experience to improve tools in the process of solving inquiry problem, experience to communicate with colleagues who conduct inquiry activities under the same subject, experience to share the results with other groups, and inquiry activities using familiar materials and phenomena.

The purpose of this study was to examine the management status of science in senior high schools based on the 2009 Curriculum Revision and the science teachers' perception of the content and a class of science. The way of managing a class was surveyed and discovered that the percentage of more than two teachers giving lessons depending on their major was higher than that of a teacher giving all the lessons. Analysis of teachers' perceptions of the content of science showed that science textbooks reflected the revised science curriculum well. However, teachers thought that the terms and concepts introduced to describe the knowledge of frontier science were so difficult that they feel it's very hard teaching them to the students. Even though science teachers thought that science was mainly focused on cultivating scientific literacy of the students, they assess mostly understanding of science concepts on the students. It means that science teachers stay in line with old position in assessment.

This study's purpose is to investigate elementary school teachers' perception on infographics learning materials. For this, this study made a questionnaire about infographics cognition or not, the need for development of infographics learning materials, science class applied infographics. And then, this study conducted a survey of 300 elementary school teachers. Through this process, this study had the results that most elementary school teachers had not some experience infographics and had never applied infographics during the class. On the other hand, elementary school teachers who had some experience said that they had used infographics in society subject and science subject. And they said that infographics was used in the development stage of class. In the need for development of infographics learning materials, this study had the results that elementary school teachers recognized the quantities of infographics which could apply in learning materials of elementary school inadequate. And elementary school teachers said that they needed infographics learning materials which could actually apply in class. Also, elementary school teachers said that the subject which could be most applied infographics learning materials was society subject and science subject. And they said that infographics learning materials was a good method which can be applied to third grade and fourth grade in elementary school. In science class applied infographics learning materials, elementary school teachers said that the best class stage to presenting infographics learning materials was full-scale lesson of each chapter in curriculum and they recognized that infographics learning materials must be used for understanding scientific concepts. Add to this, elementary school teachers recognized that the development of learning materials with the application of infographics learning materials must take precedence in order for education applied infographics learning materials to carry out successfully.

Although the reward based on group accomplishment in cooperative learning has a merit to emphasize interdependency, it may have some undesirable side effects such as free rider effect and sucker effect. For the purpose of reducing these side effects, this study examined how the adjustment of the reward structure affected the scholastic achievement, the perception of learning environments, and the attitude toward science class by adding individual reward to group reward. We selected 2 classes of sixth grade in an elementary school, and taught on oxygen and carbon dioxide for 13 class hours in cooperative learning strategies. Group reward was applied to one class, and both group and individual rewards were applied to the other class. Analysis of the results indicated that the achievement scores of the students under the group and individual rewards were significantly higher than those under the group reward. In addition, they had more difficulty in science class and felt less satisfied. The upper level students under the group and individual rewards were also found to exhibit more competition. Educational implications were discussed.

This study has developed the earth science class model based on flipped learning and analyzed the effects of that model at the elementary pre-teachers' science classes. The model of this study, the material which was consists of all contents and information about classes was offered to learners before science class as a substitute for preceding homework at general flipped learning. In science class, the knowledges which were recorded in materials were explained directly to learners by instructor for 20minutes. So the learners resolved some inquiry questions in materials through mutual debate collaboration with learners in small group. After inquiry questions' resolving, the learner among small group makes a presentation in front of the whole class. At the same time, the instructor evaluated learning action of all small groups' learners during the classes as process evaluation. The final evaluation results of semester were obtained scores of the small group in 14 classes and the achievements of individual portfolio as final exam. The learners were very positive perception to this science class model, why it is helped to concentrate on the class, extended debating and thinking ability. Consequently, the class model of this study is useful to applicate the earth science classes.

In this study, science teachers' perception and attitude toward nanotechnology are examined through questionnaires gathered from 134 secondary science teachers. As a result, the study shows that science teachers have high perceptiveness. However, they do not understand specific information on nanotechnology correctly. Science teachers have positive attitudes toward nanotechnology and they have perceived risks of nanotechnology as well as benefits of nanotechnology. Science teachers show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chip and nano-taste enhancer. Science teachers are exposed to nanotechnology via various sources such as TV and internet, whereas teachers rarely get information on nanotechnology-related concepts in textbooks and teaching resources. Science teachers have perceived many textbooks do not introduce enough nanotechnology-related concepts. Many teachers try to explain the nanotechnology when textbooks include nanotechnology-related concepts, whereas quite a few of teachers do not introduce the nanotechnology-related concepts in class.

Daily science classes, which have been continued as part of the spread of participatory science culture, has taken the lead in popularizing science as an effective out-of-school experiential and research activity. However, due to the recent COVID-19 situation, daily science classes have also become an environment in which there is no choice but to switch to non-face-to-face or to combine face-to-face and non-face-to-face education. Therefore, in this study, we examine how elementary school students participating in the non-face-to-face daily science class program change their usual fields of interest, perception of science and technology, interest about science, and scientific competency. In addition, the educational effectiveness of the non-face-to-face daily science class improved by comparing the differences in perceptions of students and parents, and future operation plans were sought. As a result of the study, after participating in the non-face-to-face daily science class program, students' interest in science and technology development, future technology, environmental pollution, and social media increased, and their interest in games decreased. Also, students' interest in science and technology activities, interest in science, and scientific competency also increased. This shows that non-face-to-face daily science class education is effective. Therefore, it was suggested that it is necessary to diversify the learning topics and content levels of the daily science class program, to expand the opportunities of non-face-to-face science education for underprivileged learners, and to develop and share science content using the latest media.
