Isomorphs of a puzzle called m+m resulted in faster solution times and an easily reproduced solution path in a labeled version of the problem compared to a more difficult binary version. We conjecture that performance is related to a type of heuristic called direction that not only constrains search space in the labeled version, but also facilitates solution by presenting an “easy to keep in mi...

The mode of Internet-enabled organization referred to here as “distributed problem-solving networks” (DPSNs) is also known as bazaar governance (Demil and Lecocq, 2006; Hope, 2008), commons-based peer production (Benkler, 2006), crowd sourcing, collective wisdom and wikinomics (Tapscott and Williams, 2007). There is currently debate in the academic literature as to how this mode of organizing r...

When a case-based planner is retrieving a previous case in preparation for solving a new similar problem, it is often not aware of all of the implicit features of the new problem situation which determine if a particular case may be successfully applied. This means that some cases may fail to improve the planner’s performance. By detecting and explaining these case failures as they occur, retri...

BACKGROUND Beneficial effects of Problem Based Learning (PBL) in medical education are often emphasized. However, there is another side of the coin. This study was conducted to find out frequency of PBL group problems in our setup and the influence of these problems on students' learning. We also compared the perception of students and tutors as regard to frequency and level of hindrance caused...

BACKGROUND Instant messaging applications have the potential to improve and facilitate communication between hospital doctors and students, hence generating and improving learning opportunities. This study aims to demonstrate the feasibility and acceptability of instant messaging communication to supplement medical education for medical students whilst on clinical attachment. METHODS A total ...

BACKGROUND Problem based learning (PBL) has made major impact on curricular designing and practice in medical education for the last forty years. Incorporation of PBL approach in medical education has been a challenge and opportunity for both educationists on how to impart change and medical teachers on how to internalise the change. OBJECTIVES This paper aimed to investigate experiences, ach...

Many learning systems suffer from the utility problem; that is, that time after learning is greater than time before learning. Discovering how to assure that learned knowledge will in fact speed up system performance has been a focus of research in explanationbased learning (EBL). One way to analyze the utility problem is by examining the differences between the match process (match search) of ...

Problem Based Learning (PBL) has been used with increased frequency in Higher Education settings since first introduced by Barrows and Tamblyn during the 1980’s. Since this time PBL has been used in medical, engineering and education faculties to support pre-service students in the acquisition of skills and content knowledge relevant to their disciplines. This paper explores the perceptions ear...

This paper presents initial efforts in the implementation of innovative methods in teaching engineering, in particular using the Problem Based Learning (PBL) approach. This paper elaborates the current practice of the PBL teaching method within the Department of Electrical Engineering, University of Malaya. Pertaining issues include the integration of the PBL method into the overall teaching me...

BACKGROUND A traditional and effective form of teaching within medical education has been Problem Based Learning (PBL). However, this method of teaching is resource intensive, normally requiring one tutor for every ten students. Team-based learning (TBL) has gained recent popularity in medical education, and can be applied to large groups of up to 100 students. TBL makes use of the advantages o...
