BackgroundBackground
The goals of education have changed:– Memorization of facts is publicized as
being less important than developing skills for problem solving and life long learning
For the past 30 years, education has been experiencing a revolution.

Example Unit: Adiabatic ProcessesExample Unit: Adiabatic Processes
ADIABATIC is a term for a process in ADIABATIC is a term for a process in which there is no net exchange of heat.which there is no net exchange of heat.
Although adiabatic processes have no Although adiabatic processes have no net heat change, this doesn’t mean thatnet heat change, this doesn’t mean thattemperature is constant!!!!temperature is constant!!!!

AirAirparcelparcel
Answer - From the air itself. Answer - From the air itself. When When the parcel molecules push away the the parcel molecules push away the outside air they give up energy. So they outside air they give up energy. So they slow down and air is cooler!slow down and air is cooler!

ConclusionsConclusions In the adiabatic unit we have demonstrated
an application of modern learning theory to address the emerging goals of education. By using technology we have shown how this model can accommodate all class sizes and how it can be adapted for distance education.
