From the Paideia School Newsletter, March 2009:
Computational Thinking is a new way of solving problems that derives from computer science. It involves approaching problems in a systematic, step-by-step manner, and building up solutions to complex problems from smaller pieces. Nowadays, computational thinking is a fundamental skill for everyone, not just computer scientists. Many educators argue [...]

Problem-based learning (PBL) is a constructivist pedagogy in which students learn in small groups by working on real-world problems. Despite its many benefits, however, this pedagogy is still not widely used in K-16 classrooms, especially with large numbers of students. Traditional human-facilitated PBL places intense demands on faculty to facilitate problem-solving sessions with small groups [...]

Problem-based learning (PBL) is an educational approach that allows students to improve problem solving and critical thinking skills while learning science. However, PBL requires significant teacher time and expertise to develop problems and facilitate small-group problem-solving sessions. With advances in technology, PBL can be used in today’s classrooms in an effective and scalable manner.
CaseBook is [...]

Problem-based learning (PBL) is a constructivist pedagogy in which students learn science and develop critical thinking skills by solving real-world problems in small groups. Studies have shown that PBL students are more motivated and become better learners. However, this pedagogy places additional demands on faculty. It takes time and expertise to develop suitable problems, to [...]

In our research, we have been developing a design framework for educational multimedia, based on the cognitive aspects of the users of that information. Design based on “cognitive media” appeals to the particular cognitive aspects of learners, whereas design based on types of “physical media” appeals to particular sensory modalities. This framework informed the design [...]

We believe that identifying media by their cognitive roles (e.g., definition, explanation, pseudo-code, visualization) can improve comprehension and usability in hypermedia systems designed for learning. We refer to media links organized around their cognitive role as cognitive media types (Recker, Ram, Shikano, Li, & Stasko, 1995). Our hypothesis is that the goals that students bring [...]

Multimedia technology presents several options to the developers of computer-based learning environments. For instance, it is common to organize information by its physical characteristics. However, organizize information based on how users understand the material might improve comprehension. This theory of cognitive media – media organized by cognitive characteristics – was examined in studies using the [...]

Network-accessible hypermedia environments offer the potential for radically changing the nature of education by providing students with self-paced access to digital repositories of course information. However, much research is still required to identify ways to best organize, present, and index multimedia information to facilitate use and learning by students. We have been developing a theory [...]

This paper describes a methodology for aiding the learning of troubleshooting tasks in the course of an engineer’s work. The approach supports learning in the context of actual, on-the-job troubleshooting and, in addition, supports performance of the troubleshooting task in tandem. This approach has been implemented in a computer tool called WALTS (Workspace for Aiding [...]

Multimedia repositories, libraries, and databases offer the potential for providing students with access to a wide variety of interconnected information resources. However, in order to realize this potential, multimedia systems should provide access to information and activities that support effective knowledge construction and learning by students. This article proposes a theoretical framework for organizing information [...]
