Expectations and interests in blended learning are increasing as universities respond to the educational flow of transition to e-lernring. This study tried to explore and understand the meaning of and the properties of blended instruction. In addition, through the literature review, this study was to find out how bleanded learning affected in teaching and learning situation. Particularly, it was to find out students' preference to the type of blended instruction. Those types are the mixed of or the unique of class instruction(off line), on line, and recorded instruction. To investigate learners' preference to the type of the instruction and also the reason of the preference, in this study, the 27 undergraduate students of the fourth grade in the major of mathematics education in the C university located in G area. By the result, most students preferred the mixed type of instruction involving off line and recorded instruction. The reason is that they could attend to the class while participating in the group activity positively and understand the content through the communication in depth and the instructor's feedback. Because of this reason, they did not prefer to the only one type insturction such as the recorded type.

For students majoring in Architecture or Architectural Engineering, describing a building with pictures and signs is equal to expressing his/her opinion with sentences and presentations. CAD (computer aided design) is a method of describing buildings, and is used practically in architecture-related companies. Many universities prescribe CAD instruction as a compulsory subject, and ABEEK (Accreditation Board for Engineering Education of Korea) requires an introduction to CAD as a basic subject for visual expression. The Architectural Drawing and CAD class in the department of Architectural Engineering of J University is a 2-credit course, with 4 hours of lectures per week. Relative to other subjects, this is insufficient for practical study. Thus, to make up for this insufficient time, the class has adopted a Blended learning system that mixes off-line and on-line classes. The objective of this research is to introduce Blended learning, and to give a case study of the CAD class using Blended learning.

As the educational media tends to be more digitalized and individualized, the learning paradigm is dramatically changing into e-learning. Existing on-line courseware gives a learner more chances to learn when they are home with their own PCs. However, it is of little use when they are away from their digital media. Also, it is very labor-intensive to convert the original off-line contents to on-line contents. This paper proposes education mobile contents(EMC) that can supply the learners with dynamic interactions using various multimedia information by recognizing real images of off-line contents using mobile devices. Content-based image retrieval based on object shapes is used to recognize the real image, and shapes are represented by differential chain code with estimated new starting points to obtain rotation-invariant representation, which is fitted to computational resources of mobile devices with low resolution camera. Moreover we use a dynamic time warping method to recognize the object shape, which compensates scale variations of an object. The EMC can provide learners with quick and accurate on-line contents on off-line ones using mobile devices without limitations of space.

Objectives: The purpose of this study was to investigate comparison of the effectiveness on knowledge improvement before and after the oral health education focusing on foreign students. Methods: A self-reported questionnaire was filled out by 40 foreign students in Sun Moon University from June 2 to September 30, 2014. The experimental group had an online oral health education and the control group had an off line education. The questionnaire consisted of oral health(10 items), toothbrushing(10 items), dental caries(10 items), periodontal disease(5 items), tooth sensitivity(5 items), oral cancer(6 items), and smoking(5 items). The data were analyzed by SPSS Win 18.0 program. Results: Knowledge scores of online education increased to average 1.257 points, and that of offline education was average of 2.56 points. There were statistically significant results for toothbrushing, dental caries, periodontal disease, tooth sensitivity, oral cancer and TMD except for smoking in offline education group. Conclusions: This study suggests that the offline oral health education is more effective than online oral health education.

Generally, a Learning Games made based on Off-line. But Today, Web based learning has been used for many educational system by aid of the development of internet technique. If Off-line learning game serviced by On-line learning game, can provide learner with interesting and growing learner's study will. In this paper, I design the Mathematical of Elementary school Roll playing game for learning based on On-line. This is matched the point of On-line game with the point of Learning. A Learner's mathematical technic will be improve by The Mathematical On-line Roll playing game for Elementary school student. A student's ability of self directed learning and solving problem is expended too.

The purpose of this research was to find differences of children's behavioral pattern between players and non players of the online game "Lineage" in on-line and off line space. As a result, social behaviors of children who play online games were less active than who don't. Based on their motive and behavior pattern in online world, four behavior patterns in online world were identified; "Single-Oriented", "Community-Oriented", "Off-Real World" and "Discriminative." Off-Real World and Discriminative players were more sociable than Single-Oriented and Community-Oriented players. And Discriminative player has more self assertive attitude than others. This study may serve as a model to understand how players will respond to the various game features and how they adopt the virtual world for their interpersonal relationships.

Traditional face-to-face university education has shifted its course to combine the advantages of both online and offline education in a blended-learning approach. However, there is still much that is unknown about the actual effect of blended learning, particularly it's learning outcomes in terms of cost effectiveness. This study qualitatively examines the costs and the learning outcomes of blended learning at an on-line college and off-line university. Online college level English pedagogy courses and blended with offline operations at an online university were studied across two semesters in terms of the quality of education, and both direct and indirect cost savings. Other causes for various learning outcomes and cost implications are proposed and validated.

This study is to find out the possibility of applying the Blended Learning which combines the advantage of face-to-face classroom instruction and e-Learning to design education. This Blended Loaming Model has five steps such as 'prepare, teach, show, interact, and collaborate'. It is designed by the learning decision points (performance outcomes, content stability and structure, audience size, and so on) and the characteristics of delivery methods(asynchronous, synchronous). This research is based on the learners' satisfaction data of each step. The number of the participants is 27 and a questionnaire with 21 items is administered. Ten items of them are designed with 5-point Likert scales and the rest of them ask learners describe the reason of their selection. The result show that learners are satisfied with the blended learning than the off-line classroom. It is expected that the blended learning can be a substitute of the off-line classroom for the effectiveness of design education.

Due to popularization of the wireless Internet and mobile devices the infrastructure of the ubiquitous environment, where users can get information whatever they want anytime and anywhere, is created. Therefore, a variety of fields including the education studies methods for efficiency of information transmission using on-line and off-line contents. In this paper, we propose the Mixed Mobile Education system(MME) that improves educational efficiency using on-line and off-line contents on mobile devices. Because it is hard to input new data and cannot use similar off-line contents in systems used additional tags, the proposed system does not use additional tags but recognizes of-line contents as we extract feature points in the input image using the mobile camera. We use the Scale Invariant Feature Transform(SIFT) algorithm to extract feature points which are not affected by noise, color distortion, size and rotation in the input image captured by the low resolution camera. And we use the client-server architecture for solving the limited storage size of the mobile devices and for easily registration and modification of data. Experimental results show that compared with previous work, the proposed system has some advantages and disadvantages and that the proposed system has good efficiency on various environments.
