McGregor, Joy – School Library Monthly, 2011
Humans synthesize whenever they see links between ideas they have gleaned from other sources. Human brains operate by seeing patterns and trying to make linkages. As students learn about a topic through creating a text-based presentation, they might have varying conceptual understandings of how they can combine their ideas with the information…

Whitaker, Robert J. – Physics Education, 2011
An experimental approach to obtaining the reciprocal relationships involved in a study of lenses is introduced. Through an analysis of the data obtained for the combination of two lenses of different focal lengths one finds a formula for the combination in terms of the data for individual lenses by arguing by analogy. This procedure then suggests…
