Under some conditions, substituting worked examples for problems or exercises enhances learning and subsequent problem solving. Under other conditions, worked examples are no more effective, and possibly less effective, than solving problems. Using cognitive load theory, we hypothesize that the critical factors for enhanced learning are whether the worked examples can direct attention appropriately and reduce cognitive load. It is suggested that worked examples requiring students to mentally…

Accounting for Beneficial Effects of Worked Examples in Tutored Problem Solving
Recent studies have tested the addition of worked examples to tutored problem solving, a more effective instructional approach than the untutored problem solving used in prior worked example
Effect of worked examples and Cognitive Tutor training on constructing equations
TLDR
Although the CT had a short-term effect on reducing errors and hint requests on CT practice problems, the worked examples were as effective on delayed paper-and-pencil tests.
When problem solving is superior to studying worked examples.
Interactions between levels of learner knowledge in a domain and levels of instructional guidance were investigated. Inexperienced mechanical trade apprentices were presented with either a series of
Can Collaborative Learning Improve the Effectiveness of Worked Examples in Learning Mathematics?
Worked examples and collaborative learning have both been shown to facilitate learning. However, the testing of both strategies almost exclusively has been conducted independently of each other. The
When worked examples don't work: Is cognitive load theory at an Impasse?☆
The expertise reversal effect and worked examples in tutored problem solving
TLDR
This work discusses how to further optimize the fading procedure matching each individual student’s changing knowledge level, and suggests that it is desirable to tailor the fading of worked examples to individual students’ growing expertise levels.
Using worked examples as an instructional support in the algebra classroom.
In the 2 experiments reported here, high school students studied worked examples while learning how to translate English expressions into algebraic equations. In Experiment 1, worked examples were

The Use of Worked Examples as a Substitute for Problem Solving in Learning Algebra
The knowledge required to solve algebra manipulation problems and procedures designed to hasten knowledge acquisition were studied in a series of five experiments. It was hypothesized that, as occurs
Learning Mathematics From Examples and by Doing
This article demonstrates the feasibility and effectiveness of teaching several mathematical skills by presenting students with carefully chosen sequences of worked-out examples and problems -
Designing Interactive Tutorials for Computer Users: Effects of the Form and Spacing of Practice on Skill Learning.
TLDR
Experimental subjects learned commands for an electronic spreadsheet by reading brief user-manual descriptions and working training problems on-line, and problem solving produced the best performance at test.
Cognitive Load During Problem Solving: Effects on Learning
TLDR
It is suggested that a major reason for the ineffectiveness of problem solving as a learning device, is that the cognitive processes required by the two activities overlap insufficiently, and that conventional problem solving in the form of means-ends analysis requires a relatively large amount of cognitive processing capacity which is consequently unavailable for schema acquisition.
This is like that: The use of earlier problems and the separation of similarity effects.
Novices attempting to solve a problem often are reminded of an earlier problem that illustrated a principle. Two experiments examined how these earlier problems are used and how this use is related
Expertise in Problem Solving.
TLDR
An examination of the shift from consideration of general, domain-independent skills and procedures, in both cognitive psychology and artificial intelligence, to the study of the knowledge base shows the importance of differences in the knowledge bases of experts and novices to their problem solving success.
Problem perception and knowledge structure in expert and novice mathematical problem solvers.
Evidence regarding the relationships between problem perception and expertise has customarily been obtained indirectly, through contrasting-group studies such as expert-novice comparisons.
