Science is a complex process, and we must not teach our students overly simplified versions of "the" scientific method. We propose that students can uncover the complex realities of scientific thinking by exploring the similarities and differences between solving the familiar crossword puzzles and scientific "puzzles."…

This article analyzes latent variable models from a cognitive psychology perspective. We start by discussing work by Tuerlinckx and De Boeck (2005), who proved that a diffusion model for 2-choice response processes entails a 2-parameter logistic item response theory (IRT) model for individual differences in the response data. Following this line…

A major goal of education is to help learners store information in long-term memory and use that information on later occasions to effectively solve problems (Vockell 2010). Therefore, this author began to use the Rubik's cube to help students learn to problem solve. There is something special about this colorful three-dimensional puzzle that…

In November 2008 at Purdue University, the 2nd Workshop on Human Problem Solving was held. This workshop, which was a natural continuation of the first workshop devoted almost exclusively to optimization problems, addressed a wider range of topics that reflect the scope of the "Journal of Problem Solving." The workshop was attended by 35…

This article describes the connection between a novel puzzle and uses of algebra to generalize the fewest moves to solve it.

Conceptual and behavioral methods for developing student abilities to think and behave creatively are presented with suggestions for their application in entrepreneurship courses. Conceptual exercises as well as the use of musical experimentation, card games, and board games as metaphors for business situations are shown to teach a variety of…

Reviews recent research on problem solving, summarizing differences between problem-solving styles of novices and experts. Also describes a text by Daniel Solow ("How to Read and Do Proofs"). Includes chapter titles for the text useful for students who wish to improve their understanding of mathematical reasoning. (JM)
