There's a lot of times when face-to-face training is the only thing that will do. Especially in the home performance industry: hands-on is the only way you can really learn to identify and diagnose energy-sucking and moisture-growing situations in a house. But to understand what you need to identify and diagnose, you need to have a good grasp of background concepts and physics, and how they impact the performance of the house.
Everything that happens in a house is caused by things you can't see and you can't hold: heat flow, air flow, moisture flow, neutral pressure plane. It can be a challenge to teach these concepts, especially to folks who are hands-on learners. Which, not surprisingly, is a high percentage of people who work with their hands.
Blended learning has been a staple of this industry's training: classroom time is mixed with field time in almost all programs. But classroom time is very expensive, to both the provider and the participant. And participants come to a course with a wide range of experience and existing understanding, not to mention differences in learning styles. Adding an online component to that blended learning package can help reduce stress in several ways.
