Augmented reality (AR), a mixture of virtual reality and reality in a computerized virtual object mounted on real environments, has been used extensively in educational studies in recent years. This study analyzed the use of mobile AR application (AR Tool) in a technical drawing course formatively to evaluate its usefulness on fourty engineering students that were failed from the technical drawing course. The students who took the course a second time in the summer semester used the AR Application. The AR tool brought the 3D models prepared in CAD. The markers or trackers where the model can be handled freely from its page was brought to the students to examine the model. The students were able to move and rotate the objects freely and they were able to look at the objects from many angles. The results indicated that the AR tool used in the course to be useful to teach the subjects of the course. As the use of AR increased, the benefits to the students were quite positive in terms of teaching and learning. This study has shown that augmented reality contributes greatly to the easier comprehension of technical drawings of parts that are quite complex to understand.

在技​​术制图课程中使用增强现实的形成性研究

增强现实（AR）是虚拟现实和安装在真实环境中的计算机化虚拟对象中的现实的混合体，近年来已在教育研究中广泛使用。这项研究分析了在技术制图课程中使用移动AR应用程序（AR工具）的形式，以评估其对四十名技术制图课程失败的工程专业学生的用处。夏季学期第二次参加该课程的学生使用了AR应用程序。AR工具带来了用CAD准备的3D模型。可以从页面上自由处理模型的标记或跟踪器带给学生检查模型。学生们可以自由移动和旋转物体，并且可以从多个角度观察物体。结果表明，该课程中使用的AR工具对于教授课程主题很有用。随着AR的使用增加，在教学方面给学生带来的好处是非常积极的。这项研究表明，增强现实有助于更轻松地理解相当复杂的零件的技术图纸。
