Some Reasons Why Learning Science is Hard: Can Computer Based Law Encoding Diagrams Make It Easier?

Law EncodingDiagrams, LEDs, may be an effective approach to promotingconceptual learning in science. This paper considers why by decomposing the problem of what makes science hard to learn into five generaldifficulties. How LEDs may address each of these difficulties areconsidered in the context of a novel class of LEDs for electricity, AVOW diagrams. Further, thedesign requirements of ITSs that exploit LEDs can be analysed in terms of the difficulties, as illustrated by the description of the positivefeatures and limitations of a computer based learning environment that has been built to exploit AVOWdiagrams for learning about electricity.
