Reports a study testing a hierarchical theory postulating that the literal reading comprehension process can be divided into separate skills that are distinguishably different from each other and which are hierarchically related. (TO)

The complexity hypothesis suggests that the hierarchical arrangement of learning tasks is related to the complexity of the task. Using a definition of complexity based on an analysis of the rules governing performance on a task, the present study lent support to the hypothesis. (Author/GDC)

Shows how elaboration theory (ET) sequences the concepts in a taxonomy and argues that the product of an ET analysis is usually in general agreement with sequencing based on learning prerequisite relationships, and that ET sequencing of taxonomic concepts will not violate learning prerequisite relationships.

The need for an empirically defensible means of sequencing instruction appears to have been the primary motivator for research into learning hierarchies. Four methods for generating candidates for learning hierarchies were reviewed: introspection, formal analysis, observation, and statistical "fishing." Experimental transfer of training…
