This study investigated whether it was more beneficial to provide the learners in computer-based learning environments access to on demand (self-regulated) help after they committed an error in problem solving or for the learning environment to externally regulate the presentation of instructional help. Furthermore, two different resentational…

Problem solving is of critical importance in many disciplines. In medicine, the clinician's ability to arrive at the correct diagnosis often means the difference between life and death. Despite its importance and a significant amount of research regarding how to improve problem solving, few unambiguous answers have emerged for promoting problem…

This article describes the purpose, development, and implementation of a cognitive-based instructional intervention and its impact on learning motivation. The study was conducted in a programming-based problemsolving course for first-year engineering students. The results suggest that the instructional intervention developed based on the…

A team consisting of three faculty members from Agricultural Economics, Agribusiness management, and Food Science with two research assistants at Penn State University has been working for three years on creating a food product case library for a problem-based learning and case-based instruction course. With the assistance of experts from the food…

Thirty six senior students in chemical engineering were randomly assigned to three treatment groups in an experimental study that examined the impact of different instructional strategies for troubleshooting malfunctions in a computer-based simulation of a chemical processing plant. In two groups, different types of worked examples,…
