We adopted the Design-based Research method in this study.The AR tool was developed with two functions. One is when students use the tablet to scan three-dimensional object, the augmented three-dimensional views of the object will appear on the screen. The other is when students use the tablet to scan the three-dimensional views cards, the corresponding three-dimensional object will show on the screen. The participants for our experiment to evaluate the AR toolwere 42 junior third grade students, with 22 students in experimental group and 20 students in control group. Our findings showed that students considered the augmented reality learning tool is helpful for their imagine themental imagery. However, neither the AR tool increased students’ motivation for learning nor it promoted students’ satisfaction on learning activities. The less effective of our AR tool may be due to the limited scanning angle of the system. Future studies should improve the features of the AR tool so that the effects of it can be maximized.擴增實境幾何立體三視圖Augmented RealityGeometryThree-dimension view
