Table 4 The interview text about structure

Global Micro-structure	*Sophomore M:* Learning organic chemistry requires mastering the microscopic structure of molecules. The process is focused on introducing the appearance and characteristics of molecules. However, many students have a problem that is difficult to imagine the molecules at learning beginning, but AR teaching solves it well
Global Micro-structure	*Junior M:* Organic molecules are very invisible, but I can see their various groups and structures by scanning their AR images
Functional Group	*Junior M:* When an AR image is presented, the detailed structure of organic functional groups can be seen. We present the structure of functional groups to students in a large, scientific and intuitive way, so that students can have a deeper understanding
Bond Length and Bond Angle	*Sophomore F:* We can see the microscopic structure of organics intuitively, and also see the size of individual atoms, even the bond lengths and bond angles between atoms
Bond Length and Bond Angle	Postgraduate M: Comprehensive operation and positioning of organic bond length, bond Angle and spatial position can further help students to develop spatial cognition
