Complex problem solving is an effective means to engage students in disciplinary content while also furnishing critical non-cognitive and life skills. Despite increased adoption of complex problem-solving methods in K-12 classrooms today (e.g., case-, project-, or problem-based learning), we know little about how to make these approaches…

This paper presents a design framework for cases as alternative perspectives (Jonassen in Learning to solve problems: a handbook for designing problem-solving learning environments, 2011a) in the context of K-12 mathematics. Using the design-based research strategy of conjecture mapping, the design of cases for a hypermedia site is described…

Examines instructional design theories and elaborates principles about when learning is promoted, i.e., when learners are engaged in solving real-world problems, when existing knowledge is activated as a foundation for new knowledge, and when new knowledge is demonstrated to the learner, applied by the learner, and integrated into the learner's…

The National Science Foundation-funded Center for Innovative Learning Technologies (CILT) is designed to be a national resource for stimulating research and development of technology-enabled solutions to critical problems in K-14 science, math, engineering, and technology learning. The rationale and operations of the Center and first-year progress…

Describes the design and development of a case-based reasoning (CBR) knowledge repository, including its case library and the search engine to support the technology integration community. The process and results of ormative evaluation following the concept of participatory design are reported to set the context for further research and…
