Technology, Knowledge and Learning Vol. 20, No. 3 (2015) pp. 299–315
In the field of mathematic problem-solving, students are often assigned well-structured problems that have specific "right" answers. However, this misses an important aspect of education, which is to allow the learner to investigate the...
Educational Technology Research and Development Vol. 63, No. 6 (2015) pp. 975–994
To date, many instructional systems are designed to support learners as they progress through a problem-solving task. Often these systems are designed in accordance with instructional design models that progress the learner efficiently through the...
The Effects of Case Libraries in Supporting Collaborative Problem-Solving in an Online Learning Environment
Technology, Knowledge and Learning Vol. 19, No. 3 (October 2014) pp. 337–358
Various domains require practitioners to encounter and resolve ill-structured problems using collaborative problem-solving. As such, problem-solving is an essential skill that educators must emphasize to prepare learners for practice. One potential...
Interdisciplinary Journal of Problem-based Learning Vol. 10, No. 1 (2016)
Current theories and models of education often argue that instruction is best administered when knowledge is situated within a context. Problem-based learning (PBL) provides an approach to education that has particularly powerful affordances for...
TechTrends: Linking Research and Practice to Improve Learning Vol. 60, No. 6 (2016) pp. 598–605
While much has been written in the field of educational technology regarding educational excellence and efficiency, less attention has been paid to issues of equity. Along these lines, the field of educational technology often does not address key...

Computers & Education Vol. 118, No. 1 (March 2018) pp. 120–132
Studies have found that students struggle to challenge their peers and engage in co-construction of knowledge when in asynchronous problem-based learning (PBL) contexts. In other settings, case libraries have been shown to support problem solving...
Technology, Knowledge and Learning Vol. 23, No. 1 (2018) pp. 177–187
In case library learning environments, learners are presented with an array of narratives that can be used to guide their problem solving. However, according to theorists, learners struggle to identify and retrieve the optimal case to solve a new...
