The purpose of this experimental study is to find out the effect of augmented reality contents based instruction on academic achievement, interest and flow of learning. The subjects were 142 students of five classes, sampled from 6th graders of an elementary school. Three classes(86 students) were taught by augmented reality based instruction and the other two classes(56 students) were taught by textbook based instruction for 2 weeks. The experimental design of the study was the pretest-posttest control group design. The results are summarized as follows: First, there is a significant difference in academic achievement between two groups. Augmented reality based instruction group accomplished higher achievement than textbook based instruction group. Second, there is no significant difference in general interest of learning between two groups. But in the interest of lessons taken by students themselves, augmented reality based instruction is more effective than textbook based instruction. Finally, there is a significant difference in learning flow between two groups. Augmented reality based instruction group showed higher learning flow than textbook based instruction group.

The purpose of this study is to find out the effect of augmented reality contents based instruction for adult learners on academic achievement, interest and flow in learning. The subject populations were 80 students randomly sampled from an IT institute and they were evenly placed into two groups. One cell as an experimental group studied with augmented reality based contents and the other cell as a control group studied under textbook based instruction for two weeks. The experimental design of this study was the pre-posttest control group design. The results are summarized as follows: First, there was no significant difference in academic achievement between two groups. Second, the group studied with augmented reality based contents showed higher interest in learning than textbook based instruction group. Finally, there was a significant difference in flow in learning between two groups. The augment reality based instruction group showed higher scores of flow than the other group. The implication of this study is that augmented reality contents may have different effects for adult learners in academic achievement compared with younger learners.

In the era of the Fourth Industrial Revolution, various attempts have been made to incorporate ICT technology into mathematics teaching and learning, and the necessity and efficiency of classroom instruction using flipped learning, virtual reality and augmented reality have attracted attention. This leads to an increase in demand for instructional contents and their use in education. Therefore, there is a growing need for the development of instructional contents that can be applied in the field and the study of teaching methods. In this point of view, this research classifies the types of teaching-learning, presents the flipped learning instruction and mathematics contents by teaching-learning types using constructivist mathematics education principles and augmented reality-based mobile applications. These methods and lesson plans can provide a useful framework for teaching-learning in mathematics education.

증강현실은 기존과는 다른 컴퓨팅 환경에 대한 경험을 제공하여 학생의 흥미와 관심을 유발할 뿐만아니라 증강된 현실에서 추가적인 학습자원을 제공할 수 있다는 장점이 있다. 이로인해 최근들어 증강현실을 활용한 다양한 교육환경과 차별화된 교육콘텐츠가 제시되고 있고, 교육적인 효과를 확인하고자 하는 연구들이 수행되고 있다. 본 연구는 기존 증강현실에 기반한 학습콘텐츠에 상호작용성을 향상시킬 수 있는 텐지블 인터페이스를 추가하여 학습자가 자유롭게 탐구할 수 있는 교육환경을 설계하는 것을 목적으로 한다. 설계를 구체적으로 진행하기 위해 2015 교육과정의 과학교과의 내용을 토대로 증강현실에 기반한 텐저블 과학실험실을 제안하였다.

Nowadays, many interface devices or training systems for the disabled are being developed and introduced with the recent development in IT technology but only few training systems for the developmental disabled are introduced. In this paper, we present a situation training system based on the argumented reality in order to help the developmental disabled to increase their management level of capability to the certain situation. Our system is specifically based on the food serving in the restaurant. This maker-based system provides trainees to safely experience various different situations and take the training session under any circumstances. The trainees for this program are able to look around with the HMD on, take the training easily by following the voice instruction, and try situational scenario.

Improving the speed of image processing is in great demand according to spread of high quality visual media or massive image applications such as 3D TV or movies, AR(Augmented reality). SIMD computer attached to a host computer can accelerate various image processing and massive data operations. MAMS is a multi-access memory system which is, along with multiple processing elements(PEs), adequate for establishing a high performance pipelined SIMD machine. MAMS supports simultaneous access to pq data elements within a horizontal, a vertical, or a block subarray with a constant interval in an arbitrary position in an $M{\times}N$ array of data elements, where the number of memory modules(MMs), m, is a prime number greater than pq. MAMS-PP4 is the first realization of the MAMS architecture, which consists of four PEs in a single chip and five MMs. This paper presents implementation of image processing algorithms and performance analysis for MAMS-PP16 which consists of 16 PEs with 17 MMs in an extension or the prior work, MAMS-PP4. The newly designed MAMS-PP16 has a 64 bit instruction format and application specific instruction set. The author develops a simulator of the MAMS-PP16 system, which implemented algorithms can be executed on. Performance analysis has done with this simulator executing implemented algorithms of processing images. The result of performance analysis verifies consistent response of MAMS-PP16 through the pyramid operation in image processing algorithms comparing with a Pentium-based serial processor. Executing the pyramid operation in MAMS-PP16 results in consistent response of processing time while randomly response time in a serial processor.
