Instructional Design and Application of Hydraulic Turbine Based on MR (Mixed Reality) HoloLens 2

Introducing HoloLens 2 based MR (mixed reality) technology into hydraulic turbine course can solve the problems that students cannot see the internal structure of hydraulic turbine and cannot disassemble the parts of the hydraulic turbine and can improve the instructional result of the course. MR will transform traditional instructional method of hydraulic turbine. MR instructional designs of hydraulic turbine were discussed in detail, such as some questions for MR instructional design, instructional design model and MR instructional design of hydraulic turbine. The development of hydraulic turbine MR course was also presented and four modules of bulb tubular turbine, such as structure module, principle module, equipment awareness module and assemble test module, were introduced in detail.
