Women engineering education programs in the United States, Europe and Australia were analyzed. From 1970s, these countries focused on the low representation of women in engineering, and carried out extensive research and programs. Numerous studies identified the causes of low representation as low interests in mathematics and science during K-12 years, classroom environments which treat women differently (often referred as chilly climate), and the masculine culture in engineering. Comprehensive approaches were taken in the development of the programs: the programs utilized the schools and universities as well as various local institutes, and the programs were designed not only for female students from elementary to graduate levels, but also for parents, teachers, professors, and school administrators. In order to adopt these programs in Korea, the problems that Korean female engineering students are facing in the education environment must be investigated first. Then, unified efforts to change the educational system, environments and culture are needed by all in engineering fields, along with nation-wide policies and funding.

Here we live in a fast changing world. The information and communication technologies have been surprisingly developing and making progress of our society. One of the benefit about the information and communication technologies is an internet. We can't imagine our life without it and it finally ends up with causing internet addiction which is called side effect of it. Most of former studies were, however, about game addiction and psychological factors of indivisual. In fact, there was not enough studies about internet addiction of computer science gifted students. If we analize the difference between computer science gifted students and average students when it comes to factors of internet addiction, we would surely be able to find out the result which is very helpful for cause analysis and its remedy. This paper examined the risk and protection factors of the former studies and choose various factors through Delphi analysis by specialists of information and science gifted students. Comparative analysis of computer science gifted students and average students was done through the test tools. And picking up unique factors of computer science gifted students, this paper shows the implication that contributes to protection of internet addiction and its remedy.

This study was conducted to identify the job stress factors of school foodservice employees and to examine the relationship between job stress and turnover intention through path analysis. Data was collected using a survey of 432 school foodservice employees in elementary and secondary schools in Masan, Kyungsangnam-do. All of the participants were female, and 165(52.9%) were over the age of 45' Additionally, 310(99.4%) of the respondents were married, while 287(92.0%) had less than a high school level of education. Furthermore, 271(86.9%) of the respondents were cooks. Overall, 107(34.3%) of the respondents had worked in the food industry for less than $5{\sim}10$ years. In addition, 208 (66.7%) respondents answered that they had 'never' changed jobs. Among job characteristics that causes job stress, job posture was the primary stress factor, followed by heavy work load and job condition. Job stress was found to be significantly correlated with turnover intention. Additionally, job position was the only moderating variable that was found to be correlated with job characteristics and job stress. Finally, the moderating variables influencing the effects of job stress on turnover intention were identified as performance confidence, job career, and job position. The results of this study will be useful for future studies conducted to evaluate the development of job environments and performance to minimize turnover and job inefficiency as a result of job stress.

The algorithm in computer science includes skills to design a problem solving process for solving problems efficiently and effectively. Therefore all learners who learn computer science have to learn algorithm. Education for algorithm is effective when learners acquire skills to design algorithm as well as ability to use appropriate design skills solving problems. Especially since it is heightened people awareness to cultivating informatics gifted students who have potential of significant impact on society, many studies on how to teach them have been in progress. Therefore in this study we adopted puzzles to help informatics gifted students learn skills to design algorithm and how to use them to solve problems. The results of pre and post test compared to traditional algorithm learning, we identified that puzzled based algorithm learning gave a positive impact to students. Students had various problem solving experience applying algorithm design skills in puzzle based learning. As a result, students of learning and learning transfer has been improved.

This study assumes that recognition about scientific creativity may differ according to teacher, students and parents, and that this difference can affect the actual teaching, encouragement, and development of scientific creativity. Based on teacher's free responses and literature reviews about features of scientific creativity, we extracted 16 items describing contrary views about scientific creativity. Using these 16 items, we obtain responses from 652 students, teachers, soon-to-be-teachers (college of education students) and parents about whether they agree with each item or not. Results show that 1/4 of the participants agreed with the views contrary to the views accepted in literature. And we found out which views contrary to the accepted views in literature were agreed upon by participants, and that which items divided the groups for having contrary views. From these results, we discuss the possible effects of participants' recognition on teaching, encouragement and development of scientific creativity, and suggest so further studies.

This study aims to investigate the online class preference depending on students' gender and school level. To achieve this aim, the study conducted a survey on 4,803 elementary, middle, and high school students in 17 regions nationwide. The valid data of 4,524 were then analyzed using the Apriori algorithm to discern the associated patterns of the online class preference corresponding to their gender and school level. As a result, a total of 16 rules, including 7 from elementary school students, 4 from middle school students, and 5 from high school students were derived. To be specific, elementary school male students preferred software-based classes whereas elementary female students preferred maker-based classes. In the case of middle school, both male and female students preferred virtual experience-based classes. On the other hand, high school students had a higher preference for subject-specific lecture-based classes. The study findings can serve as empirical evidence for explaining the needs of online classes perceived by K-12 students. In addition, this study can be used as basic research to present and suggest areas of improvement for diversifying online classes. Future studies can further conduct in-depth analysis on the development of various online class activities and models, the design of online class platforms, and the female students' career motivation in the field of science and technology.

This research aims to have some implications for revision of curriculum and textbooks by analysing connections between the 2009 revised national curriculum and its textbooks in elementary school mathematics. The results of analyses for 3~4 grades can be summarized in four aspects: Firstly, we noticed that the reconstructed achievement criteria were reflected properly in the textbooks except for use of calculators in 'Numbers and Operations'. Secondly, the analysis of connections between unit objectives of textbooks and the reconstructed achievement criteria suggests that 10 units must receive attention. Especially, the range of decimal numbers for adding and subtracting needs to be corrected. Thirdly, mathematical terms and symbols excluding 'unit fraction' were found in the textbooks. Finally, mathematical processes were also fully reflected in the textbooks. However 'simplifying' as a strategy for problem solving was only missing. This result shows good or poor connections between the curriculum and its textbooks, therefore it is expected to be used effectively to revise the national curriculum for mathematics and its textbooks.

The purpose of this paper is to introduce the current studies and research methods about Learning Progressions disseminated to several countries including the U.S. since 2006. It also provides a methodological base to investigate learning progressions in science by introducing a case study of learning progression conducted in Korea. For this study, we described several features of current studies on learning progressions in the U.S., and reported the common ways and sequences employed in examining learning progressions especially with respect to assessment for learning. Learning progressions are descriptions of developmental pathways of learning a topic, in which science knowledge is used in students' engaging in science practices. Each learning progression consists of upper anchor, lower anchor, and intermediate steps that connect both anchors. In investigating a learning progression, researchers usually utilize Wilson's four building blocks of assessment system based on the assessment triangle. This kind of method was also applied in investigating the learning progression for water cycle in this study. We discussed implication and consideration for the future research on learning progressions in science in Korea.

In physics education, language is an fundamental learning tool as in other subjects. In writing activity, students can get fair opportunities to express their own ideas during the class. Even though there are various styles of writing, students are usually supposed to make a report in their science classes. But there have been few studies in science education on the tasks and features of student's science writing. In this research, different styles of writing tasks were designed for science classes, and students' writing was analysed in terms of conceptual and emotional aspects. Also the usefulness of each task type was discussed relating to school physics education. Four types of writing, i.e. , , , and writing were developed, and 'The reflection of light' was selected as the theme and given to students. Four types of writing were analysed in this paper. In each type of writing, students showed different features in their conception. They also showed emotional expressions in imaginative writing types, that is, and types. Based on these results, it is recommended that in physics teaching various types of writing need to be designed, developed and applied according to the aim of a particular lesson.

Purpose: The objective of this study was to study the effect of the obesity control program to the extent of the overweight children's knowledge about obesity, physical exercise, dietary habits and the extent of obesity. Methods: A total of 61 elementary school children between the age of 9-12 were chosen for this study: 31 overweight children whose extent of obesity exceeded over 20% when measured using Broca index and other 30 overweight children of the same category for the comparison as a control group. The obesity control program made up of regular physical exercise for five days per week and a weekly diet education and consultation was implemented for the period of 8 weeks. Results: The knowledge about obesity, regular physical exercise, and diet habits were significantly improved after implementing the obesity control program, as compared to the control group. But the extent of obesity was not significantly decreased. Conclusion: These results suggest that the studies are needed to define factors of effective program and develop the effective program for decreasing the extent of obesity.
