The vast majority of students’ alternative ideas about energy could be classified into seven alternative frameworks
Misconception
- Anthropocentric - energy is mainly associated with human beings
- Depository - some objects have energy
- Ingredient - energy is dormant within some objects and can be released by some trigger
- Activity - energy is identified by overt displays – the display itself is energy
- Product - energy is a relatively short lived by-product of some situation
- Functional - energy is a very general kind of fuel for technical devices
- Flow-transfer - energy is a physical fluid that is transferred in certain processes

What's wrong with 'forms of energy'? (11-16)
Ref - Practical physics; Energy; Introducing energy; What's wrong with 'forms of energy'?
Many textbooks and teaching schemes talk of ‘transforming’ energy, or of ‘converting energy from one form to another’.
This is a very common way of talking, but it has its problems. Particularly, it is in danger of saying nothing at all. For example, “A torch converts chemical energy in the battery to light energy”. All this says is that a chemical reaction happens and light comes out.
The really important thing is to work from very early on with actual quantities of energy, to do plenty of simple sums about amounts of energy and rates of delivery. This is where there is real payoff; where something is actually being said, and understanding has something to get a grip on.

Energy: a common currency (11-14)
Ref - SPT En01 PN01
All of our everyday activities, whether driving to school, doing the washing-up, or going for a walk, have a cost. The cost we are thinking about here is not one of money, but one of energy. In fact, energy provides a common currency that allows us to count the relative cost of all of these different kinds of activity.

"A two-part study designed (a) to find the relation, if any, between junior high school students’ alternative frameworks on energy held prior to instruction and their cognitive level of operations, either preformal or formal, and (b) to determine the relation, if any, between junior and senior high school students’ success or failure in learning about energy and their alternative frameworks, their levels of cognitive operations, and their tendencies toward open- or closed-mindedness." - M.
