2. Inductive Discovery Learning: Design and Consideration
2.1 Define critical attributes of a concept, and focus on one attribute at a time
Every concept has four elements: a name, examples, attributes, and value of attribute [2]. To
have students see what is expected to be seen, the critical attributes have to be identified and
singled out [8]. Take the meaning of denominator as an example, critical attributes include
the number of parts and whole, and each part is equal. Separating critical attribute of a
concept and only presenting one at a time make students learning material easier.
2.2 Make the critical attribute obvious
Once the target critical attribute is decided, it has to be obvious to be noticed. Lo, Pong, and
Chik [8] pointed out that people tend to aware something when (1) the thing keeps change
while other things remain the same; and (2) the thing remains the same while other things
keep change. For the first situation, if the target attribute of denominator is the number of
parts into which one whole is divided, similar examples can be given. For example, the pie
graph share the same representation, which only the numbers of parts are different so that
the meaning of denominator can be discerned. Or, for the second situation, examples of
different representations can be given while the fraction number keeps the same.
3. Design structure and ideas of learning material
ICCE2010 | 744
Before design learning material, we had to analyze and identify the structure of each
conception in detail. The content design must focus upon each unit of the phenomenon [8],
so one page only taught one critical feature to avoid students misunderstanding what we
expected. Students must follow learning steps to discover the critical feature relevance.
