디자인 분야에서 온라인, 모바일을 통한 융합교육의 보급이 빠르게 확장되고 있다. 특히 증강현실 기술을 응용한 교육 프로그램 개발이 점차 널리 사용되고 있다. 이 글은 우선, 증강현실 기술의 현재 상태와 장점을 검토함으로써 교육 응용 분야에서 증강현실의 필요성을 강조한다. 둘째, 필자는 새로운 유형의 교육 시스템인 "AR + E" 교육 클라우드 플랫폼 시스템을 제안한다. 이 시스템은 일반 종이 교과서, 범용 휴대용 이동 단말기와 APP 등 3가지로 구성된다. 본 연구는 자동차 정비 전공 학생들을 대상으로 하여 "AR + E" 교육 시스템의 유용성 및 성능 실험을 통해 "AR + E" 시스템이 학습 효과에 미치는 영향 연구 조사하였다. "AR + E"시스템은 전통적인 학습 그룹과의 비교 실험을 통해 AR 대화식 미디어를 사용하여 학습자의 학업 성과를 향상시킬 뿐만 아니라, 재미와 참여도 및 연속성을 향상시키는 결과를 얻게 되었다. 끝으로, 사용자 경험, 행위와 기호에 대한 관찰과 인터뷰를 통해 AR 기반 교육 프로그램 소프트웨어를 디자인하고 개발하여 제안하고 있다.

Abstract ▼ AI-Helper

With the popularization of online learning, mobile learning and blended learning model, augmented reality technology is increasingly widely applied in the field of education today. This article stresses the necessity of applying augmented reality to education by summarizing the current situation and advantages of augmented reality technology in education. Next, the author proposes a new education system-"AR+E education cloud platform system". Last, the author proposes several inspirations for the design of AR-based education software according to the observation and interview of the behaviors and preferences of the respondents.

문제 정의

The author believes that future iterative design of the “AR+E system” will continue to use AR technology to present future educational method, valuably combine with individualized teaching, and create a learner-centered learning environment.
The purpose of the experimental study of this project is to study whether the use of "AR+E learning system ”(hereinafter referred to as "AR+E system”) helps learners learn and operate automobile engine and helps them improve their ability to learn, ability to acquire knowledge and practical operating skills, thus reinforcing their professional confidence and sense of achievement.

가설 설정

3. Are you more willing to use “AR+E learning system”rather than a traditional model to learn about the structure and principle of engine?
H0 :(μ1-μ2) = 0, there is no evidence supporting the viewpoint there is a significant difference between the traditional group and the AR group in academic records.
H1 :(μ1-μ2)> 0, AR group is obviously better than that of the traditional study group in terms of academic records.

제안 방법

After 40 students finished four weeks of course learning, a knowledge test and a simulated operation test were adopted to test their skills. Their learning quality was evaluated by testing their knowledge about the following five training modules.
The objective part mainly refers to some measurable and trackable indicators. After students finish studying the installation of automobile engine, they received a simulation operation test, and test results of the students or scores given by their teachers were used for evaluating the learning effectiveness of the two methods (AR+E system-based teaching model and traditional teaching model) as data for the objective evaluation experiment.
The experiment consists of five parts, as shown in Table 1. The author also prepared some tools to guide users to test and measure other variables in the experiment, including user test guide, test consent, pre-test questionnaire about personal information, and SUS questionnaire. With the usability-related questionnaire, we can know the level of usability of a product, and we can know user preferences and their other needs through interview.
The proposal of this concept is a product of education supported by technology in the context of the era of information technology, and the concept of “AR+E system” is the actual application of AR technology to education with a cloud platform as the carrier by using internet thinking.
The respondents of this test were asked to fill in the SUS after the experiment ended and rank it from “1 to 5”, then it is necessary to convert the score of every item.
After 40 students finished four weeks of course learning, a knowledge test and a simulated operation test were adopted to test their skills. Their learning quality was evaluated by testing their knowledge about the following five training modules. We collected the tests cores of 20 students in the traditional group and 20 students in the AR experimental group, see Table 2.
This experimental study adopted a qualitative analysis to ascertain students’ satisfaction with AR+E system.

대상 데이터

The participants of this educational experiment are 40 students majoring in automobile maintenance who have attended training about the practical operation of automobile engine and received a test about the “AR+E” system.

데이터처리

For the results of the independent sample t-test after the two sets of score-related data were collected. Result shows that the p-value of the mean is close to 0.
To compare two sets of data about scores, independent sample t-test was used for data analysis. The author compared the traditional study group a (μ1) and AR study group B (μ2) and checked whether the p-value of the t-test reaches the significance Level in light of the outcome.

성능/효과

As AR technology is increasingly widely used in the field of education at present, this article focuses on discussing the advantages of AR technology in the context of education, and it is found by developing, demonstrating and test actual cases that AR technology can influence students’ learning outcome and make learning more interesting, participatory and sustainable.
