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.


Our understanding of learning has increased:– Theory and evidence are favoring a

knowledge construction model over the information transmission model



Technology is increasing in capability and availability:– School computers are more common– Internet access is more widespread– Java has made instructional software more practical


ChallengeChallengeHow can educators use the new

knowledge about learning to realize the emerging goals of education for all class sizes and diverse and dispersed learners?

One approachOne approachEmploy greater integration of

technology to better structure the learning experience and to provide management tools.

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

An air parcel, like a balloon, An air parcel, like a balloon, expands as it moves upward in expands as it moves upward in the atmosphere.the atmosphere.

AirAirparcelparcel

It takes energy for the air molecules It takes energy for the air molecules in the parcel to move the existing air in the parcel to move the existing air molecules out of the way. Where molecules out of the way. Where does the energy come from?does the energy come from?

AirAirparcelparcel

We know that it can’t be conduction We know that it can’t be conduction or radiation from outside sources. or radiation from outside sources. These are too slow. What is left?These are too slow. What is left?

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 Summary of activities

– Exploration of the concept– Information related to exploration– Reinforcement of concepts– Integration in authentic setting

Why technology?– Stronger course objectives

• Computer addresses low level objectives• Teacher can address higher level objectives

– Individualized learning opportunities– Student directed

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.
