Limitations of modern artificial intelligence are most evident in comparison with the human ability to selfregulate cognitive and learning processes. Is it possible to model the human self-regulation ability in artifacts? And vice versa, can a computer model of this sort help students to develop self-regulation skills? This work describes a blueprint of an(More)
The purpose of this case study was to examine students' perceptions of their learning experiences while working on a real world instructional design project in a performance oriented team in the context of a situated and problem-based learning environment. Participants were 11 graduate students enrolled in a learning-by-doing instructional design program.(More)
The purpose of this exploratory study was to examine college instructors’ self-reported use of integrative learning technologies (ILT) to support student selfregulated learning (SRL) in online or blended learning environments. Participants were 12 experienced online instructors in a large mid-Atlantic university. Participants responded to a questionnaire(More)
Implementation of agency in a cognitive system implies that certain beliefs, values and/or goals represented in the system become, if implicitly, attributed to the self of the agent.
