Virtual Reality in Education
Virtual Reality in Education has been used for:
Laparo-scopic Colectomy
Particle physics
Neurosurgery
Electrical Engineering
Others
Provides a cost-effective approach to lab-based education
Wind Energy
In the United States a total of 13.1 GigaWatts (GW) of wind power was added in 2012.

Virtual Reality for Wind Energy Education
Learning Outcomes
We emphasized on the following
Fundamentals of windmill design
Fundamentals of wind farm design
Optimizing the placing of windmills
Fundamentals of wind farm economics
Module 1 – Airfoil Module
Relationships between blade angle and
Lift Coefficient
Drag Coefficient
Module 2 – Single Windmill
Characterizing the functional relationship between power output and wind-speed for a single windmill
Designing a windmill that can provide the maximum power output given a particular windspeed
Add picture
Module 3 – Windfarm
Characterizing the overall output of the wind farm as a function of windmill array geometry
Designing a wind farm that will maximize power output for a fixed cost
Assessment
Real-time formative assessment
Inspired by Dewey’s conception of “an experience” in education and play that should be sensitive to students’ goals and interests, we have implemented an adaptive system that capitalizes upon learners’ natural curiosities
Learners are asked questions dynamically in response to specific events that they have triggered
Design-based summative assessment
Students are allowed to explore the key parameters of the windmills
Keeping one parameter constant, students are asked to characterize the power output for a variety of parameter values
Generating graphs for key parameters
Rotor Power vs. Windspeed
Rotor Power vs. Pitch Angle of the rotor blades
Rotor Power vs. Number of rotor blades
Rotor Power vs. Length of the rotor blades
