The purpose of this study is to develop a contents when we are going to introduce cryptography and information security for vocational high school students. For this we do a survey of the students' level for understanding of information security and the 7th curriculum for school mathematics, 2007 revised curriculum for school mathematics, the curriculum for vocational high school, and we search for the material that connects between mathematics subjects and vocational subjects. We develop a text book that introduces information security and cryptography. After we teach vocational high school students by using this developed book, we get the result that learning cryptography with computer programming makes a good motivation of learning mathematics and roles a parameter between mathematics curriculum and vocational curriculum. As a result we propose that the developed contents can be used in 'Practical Mathematics' in the 7th curriculum for school mathematics or 'Application of Mathematics' in 2007 revised curriculum for school mathematics.

It is possible to increase integrated thinking and problem solving ability ultimately through STEAM education. This study developed STEAM model to apply to subjects and scratch knowledge education that sixth grade students in elementary schools can learn each subject through STEAM learning by applying scratch programming and it was applied and analyzed during regular classes and afterschool classes for sixth grade students. As a result, it was possible that about 70% of sixth grade students, the subject of model application were able to do STEAM learning initiatively by applying scratch program. Other 30% of the students were able to do STEAM learning partially through scratch. As for the achievement assessment of STEAM learning, it was evaluated that most of the students for the evaluation subjects got satisfactory achievement level by getting overall average 7.83 out of ten. Thus, it is considered that STEAM learning model by applying scratch is very superior that applying existing programming language such as C, BASIC etc.

In this study, we performed experimental studies on the educational programming languages of Dolittle and Robot to compare and analyze their effect on improving creativity. We formed three sixth grade classes, totaling 99 students, into a Robot class, a Dolittle class, and a general class that served as a neutral. The Dolittle class and the Robot class took ten programming lessons with specific hand-in operations, as well as feedback and discussion, during ten weeks. The experiment results showed that student creativity in the two programming classes improved more than that of students in the general class. Especially creativity of the students in the Robot class improved the most. Moreover, the mean creativity of the lower academic achievement group was slightly better than that of the higher group. This implies that there is no positive correlation between academic achievement and creativity.

The college student times corresponds to the stage of important transition from social aspects. Thus, this study were carried out to propose the necessity of recognizing and managing its importance by grasping family strength parts of students majored in dental hygiene that affected influences to ego-resiliency. The study was composed of 553 girl students who were studying in department of dental hygiene, 3-year system at 6 colleges. Regarding to collecting datum, it was performed from September to December 2012 through examiners' interview questionnaires. Component parts of the family strength affecting influences to confidence, interpersonal effectiveness, and optimistic attitudes that were constituents of eco-resiliency appeared to communications between family members and sharing of value system from the members. Through above results, it is judged that dialogue-promoting programs by which verbal-nonverbal transfer processes could be formed have to be made in order to strength component parts of the family strength, and programs that were able to bring up students' humanistic knowledge shall be activated in school.

This study presents a step-by-step analysis of the experiences and discussions of five elementary school teachers while developing the Augmented Reality (AR) science educational materials, using the Unity Physics Engine. In the preparation phase to develop the AR materials, the teachers explored the features of the AR technology and decided to create AR materials for experiments related to magnetic fields in the magnetism unit, based on discussions about the unit selection. In addition, they complained about difficulties arising out of the lack of background knowledge about the C# programming language in the preparation phase. During the material development stage, there were difficulties in operating the unfamiliar interface and other functions of the software. However, this was overcome through knowledge sharing and collaborative communication among the teachers. The final materials developed were marker-type AR materials to perform experimental activities by changing the position of the magnet and the compass markers. Based on the developed materials, the teachers discussed their smooth utilization during the classroom activities.

The purpose of this study is to examine North Korean defector students' characteristics in science learning through their voice in an "Angbuilgu" program, one of the Korean traditional science knowledge (TSK). We compared them with two other groups of contrasting backgrounds. The Angbuilgu program contains meaningful questions of time, everyday-life knowledge, Korean TSK, and western modern science (WMS). The teaching strategy consists of interactions between teacher and students, and scientific experiments. We applied this program to three groups and analyzed: North Korean defector students, elementary science gifted students, high school students in an advanced class. The characteristics of their science learning show the following: First, their interpretation of time as nature itself in their everyday life. They have rich experience and are familiar with time in nature. Second, they prefer science with complementary, caring, and humanist perspectives, which is in contrast to other groups with preference to the updated and practical science. Third, they lack scientific concepts but possess an abundance of everyday-life knowledge. Their linguistic expressions are ordinary rather than scientific. Fourth, they are familiar with narrative thinking more than scientific thinking. The results show that the science program using Korean TSK can help them accept new scientific knowledge as well as cultural pride, which plays a role in reconfirming their identity as one ethnicity. We expect that the contents of Korean TSK can be an intercultural field between North Korean defector students and our science curriculum.

The purpose of the study was two folded: to examine whether form-focused instruction (FFI) with corrective feedback (CF) is effective for the acquisition of the target linguistic forms and to find out the extent to which of the students' perceptions as well as their attitudes towards English instruction that they received. Tests and questionnaires were implemented to 122 Korean EFL students from eight classes enrolled in an English communication course. They were randomly assigned to three groups: the input-based group, who received typographical input enhancement materials, so-called the TIE group, the output-based group, who performed dictogloss tasks, so-called the DICT group, and the control group (CG). The data analysis was made on both tests and questionnaires by using SPSS 21.0 for Windows. The study found that different types of FFI with CF contributed to the improvement of students' grammatical knowledge and both the TIE and DICT task group students positively changed their perceptions and understanding as well as their attitudes towards the English instruction given, and students in all groups preferred pair work activities. In addition, most of the TIE and DICT students showed their interest and satisfaction with English class, whereas the CG group students did not. Based on the findings, this study suggested that well-planned and properly-chosen FFI in the form of pair work activities should be applied in classrooms with consideration of students' instructional preference in Korean EFL contextual settings.

The purpose of this study is to draw a general conclusion through summing up theses on parents' need for their education up to the present. The subjects of this study are 25 masters' degree theses on parents' need for their education in the kindergarten from 2001 to 2010. The results of data on parents' education method and style were conducted by frequency analysis. Also it was surveyed if in how many theses the contents of parents' education were rated over average points by Licker. The results of this study are as follows: First, the parents think that the proper frequency of their education is once or two in a semester and the favorite time is from 10 to 12 o'clock or from 2 p. m. to 4 p.m. They also want to learn on Wednesday, Friday and Saturday. And they want a professional as their lecturer the most and then a homeroom teacher. Secondly, in the survey of their education style they like more lecture or a short course than any other thing, and then they like home messenger, group council and so on. But especially they don't like the style of visiting class, book lending, ceremony/class assistance, practice (workshop), and visiting home. Thirdly, they want to know a general guide in the kindergarten of the contents of their education a lot. And they want to know some of a budget, program, and assessment of a principal and the teachers in the kindergarten. Fourthly, they want to know all parts of the parents' roles related to rearing their children in their own elements of the contents of their education above all. And they also want strongly their free time, hobby, the liberal arts, amusement and recreation. Fifthly, in the view of infant development they want strongly to know how to communicate with their children rightly, and how to adjust their children's activities and how to praise or blame their children. And they also want how to form their children's right habit and to guide their children's right acts in the infant period the most. Lastly, they want to know children's physical development and their cognitive development in the view of infant development the most. And then they want to know the development of sociology, creativity, morality, and emotion in good order.
