The purpose of this study was to investigate the effects of learning style on blended learning. Subjects were 102 college students(grade 1, department of physical therapy) who enrolled in 'neuroanatomy' course. Blended learning was composed of 13 weeks-3 hour/1week in offline and 16 chapters-24 lessons in online. According to Kolb's learning style, assimilator was the most common. There were no significant differences between the learning style but, they were most preferred blended learning(92.1% of subjects), improved participation and excitation in learning(each 55.5%, 58.8% of subjects), and blended learning was helpful in learning(85.1% of subjects). In student's satisfaction, there was significant difference between the learning style. Statistical difference was found in satisfaction between assimilator(80.7%) and accommodator(67.5%).

The purpose of research is to analyze research trends and methods in a total of 709 studies published in five domestic mathematics education journals issued by Korea Citation Index (KCI) for the last 10 years (2003-2013) and strands in stages of research methods among mixed methods studies. As a result, the majority of articles in the five journals used either qualitative or quantitative methods and mixed methods research was less than 10 % of the total number of studies. The majority of mixed methods was research equally mixing qualitative and quantitative methods. The mixed methods research consisted primarily of quantitative with descriptive statistics and very little qualitative with conceptual framework based on theoretical background. Our results provide not only trends of the current research methods, but also implications for various future research paradigms in mathematics education.

In theory, mixed methods that incorporate both quantitative and qualitative approaches can maximize strengths of each method while minimize the short comings of each. Mixed methods research is a feature of educational research nowadays, and the number of studies applied mixed methods research has been gradually increasing. This study investigates how mixed methods research was applied in the field of mathematic education, especially focusing on how qualitative and quantitative methods are combined to best address their research questions. With this in mind, this study carefully selects and analyzes 4 research articles that used mixed methods and were published by Journal of Elementary Mathematics Education in Korea in 2015. This study provides detailed result of qualitative analysis on mixed methods research while other a few previous analysis on mixed methods research were tend to focusing on quantitative analysis, producing numeric quantitative information. The result of this study provides practical and in-depth analysis on how to improve validity and possibility of mixed methods research, addressing alternative ways to combine two different research methods and key elements to take into account.

국방부에서 발표한 ‘국방개혁에 관한 법률’ 에 따라 2014년까지 현역병들에 대한 복무기간이 단계적으로 단축될 예정이다. 이에 따라 좀 더 효율적인 직무교육 방안이 필요하게 되어, ‘차등제 교육’을 시행하고 있다. 이 교육의 효과를 향상시키기 위해서는 훈련병들의 예상 학업 성취도를 미리 정확하게 예측하는 것이 필수적이다. 따라서, 본 연구에서는 입교 초기에 얻을 수 있는 신병들의 제한된 자료들을 이용하여 교육 성취도 예측 모형을 개발하였다. 본 모형의 목적 변수는 ‘일반관리 인원’, ‘집중관리 인원’의 값을 갖는 이진형 성취집단 변수이며, 사용된 기법은 k-means 군집기볍과 Decision Tree 기법을 혼합한 모형, k-means 군집기법과 Neural Network 기법을 혼합한 모형, Decision Tree 모형, Neural Network 모형, Bayesian 모형, 그리고 Logistic 모형 등을 사용하였다. 그 결과 k-means 군집기법과 Decision Tree를 혼합한 모형이 가장 좋은 예측력올 보이는 것으로 나타났다. 이러한 교육 성취집단 예측 모형은 향후 군에서 이루어지는 다양한 교육 프로그램에 적극적으로 이용될 수 있을 것으로 기대된다.

The purpose of this study is to analyze how the qualitative research is applied to mixed method research and thereby to gain an insight to suggest reasonable ways of employing qualitative method in order to accomplish intended goal of research, especially in the field of mathematics education. For that purpose, this study carefully selects and analyzes 5 article that used mixed method and were published by Education of Primary School Mathematics Journal in 2012. Unlike those a few previous studied on mixed method that focused on producing general trend by simply showing quantitative information on what the frequence of used research topic, content, methods combination, quantitative methods, and qualitative methods, this study provides detailed result of qualitative analysis on mixed studies. In sum, this study concludes with practical and in-depth suggestions on how to improve validity of mixed research and qualitative research in the field of mathematic of education.

Using the Operating Systems course that is offered by online, a blended learning mixed up with face-to-face lecture and e-learning for O.S. course has been carried out. In order to find a efficient management way of the blended learning, we build up two groups: one group named 01 takes a class which consists of two hours face-to-face lecture and one hour online study per week and the other group named 02 takes a class which consists of two hours online study and one hour face-to-face lecture. According to the result of a mid-term examination, the Cohen's d between two groups is 0.165. It means the small effect size. The 01 group has higer average and smaller variance than 02 group. However, 02 group has more students who earn high score than 01 group. In conclusion, if students can well carry out the self-regulated learning, then the blended learning mixed up with 02 group style is suitable. Otherwise, face-to-face lecture or the blended learning like 01 group style is suitable.

Realistic content such as virtual reality, augmented reality, and mixed reality is emerging as an innovative technology in the education field in that it allows people to safely and efficiently experience dangerous, expensive or impossible situations, such as disaster training or space travel. Recently, as government agencies have supported a lot for producing virtual augmented reality contents about education, various educational contents using virtual augmented reality technology have been developed through the Edutech industry. Many virtual augmented reality-based educational contents are being developed, but mixed reality-based educational contents are very limited which could be more effective for education. This study examines the basic method of producing mixed reality educational contents using Hololens and, on the basis of this, it proposes the method for producing scientific experiment contents. Hololens made it possible to share information in real time without a regular desktop PC, and it is effective for teachers to manage and evaluate students in real time.

오늘날 인터넷 활용이 본격적으로 대중화되면서 교육현장에서도 웹을 기반으로 한 다양한 교육방법이 연구, 개발되어 WBI 학습, 웹 기반 CAI, 원격강의 등의 가상교육으로 발전되어 왔다. 웹 기반 교육이 교실수업에 비해 가지는 장점을 최대한 살려서 현실성 있고 효율적인 교육의 효과를 얻으려면 학습자의 능력과 관심 , 흥미 , 적성 등을 고려한 웹 기반 수업 모형 개발이 요구된다. 본 논문은 제7차 교육과정에서 실시되는 단계형 수준별 교육과정에 심화보충형을 혼합한 수준별 수업모형을 웹 기반 수업모형으로 제시하고자 한다. 웹을 기반으로 한 혼합형 수준별 수업이 가능해짐으로써 교수자는 웹 데이터베이스를 통해 학습의 촉매자, 조언자로서의 역할을 할 수 있으며, 학습자는 학업 성취수준에 알맞은 학습 구성이 가능해짐으로써 보다 효과적인 자기주도적인 학습이 이루어질 것으로 기대된다

Mixed reality(MR) technology combines the advantages of virtual reality(VR) and augmented reality(AR) technology, allowing MR users to interact with virtual objects against the background of the real world. In addition, since virtual objects interact with the real world, users can experience a higher immersion. This study proposes electric circuit practical training content using Meta Quest Pro to produce immersive MR content based on reality. To this end, first, the development process for producing MR content by linking Meta Quest Pro equipment with the Unity 3D engine is organized. Then, based on the traditional electric circuit practical training method used in elementary school science classes, virtual electric circuit practical training content with the same training method and operation process is produced based on MR. Finally, survey experiments are conducted to analyze the presence and experience of the MR-based educational environment provided using the produced content. Through this, the usability of the proposed practical training content is evaluated and future research directions are suggested.
