Introducing new concepts to learners in an order of increasing complexity appears to be beneficial for learning, but typically introduction of concepts does not always adhere to this principle. We examined whether introducing new algebra concepts in a contrasted manner or in an order of increasing complexity instead of a different more typical…

Example-based learning often uses a design in which learners first receive basic instructional explanations of new principles and concepts and then examples thereof. In this sequence, it is crucial that learners self-explain by using the content of the basic instructional explanations to elaborate on the examples. Typically, learners are not…

Instruction often starts with an explanation of a concept or principle before students are presented with problems to be solved. Recent research indicates that reversing this widely used tell-and-practice sequence (T&P) so that exploratory problem-solving precedes the instructional explanation (i.e., PS-I) might be more beneficial. We aimed 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)

Computer-naive university students (N=124) were taught the BASIC programing language by solving and receiving feedback on program comprehension problems stated in BASIC or on corresponding problems stated in English followed by problems stated in BASIC. Results support a sequential method of instruction beginning with use of natural language…

For college students learning concepts, the advisement condition resulted in better performance than the learner control condition and needed less instructional time than the adaptive control condition. Results also indicated that students given concepts simultaneously performed better and needed less instruction than those who received concepts…

Senior high students who were given concepts simultaneously learned more than those who received concepts successively. A second variable, instructional control strategy, contrasted an adaptive (computer-assisted) control strategy with learner control. Performance was above the criterion level for the adaptive condition, but below it for learner…
