    Learning through complex problem solving has received increased attention in educational areas. This is particularly the case in challenging domains such as medical education, where problem-based learning (PBL) is widely adopted and found to be effective in helping students to improve their abilities in clinical reasoning, problem solving, and self-directed and cooperative learning. However, there are concerns about PBL’s effects on development of systemic knowledge structures and efficient reasoning processes, which are critical for expertise development. To address the challenge, a technology-enhanced learning environment is proposed in this study, aiming to improve students’ complex problem-solving expertise by scaffolding their problem solving or reasoning processes as well as knowledge construction with support of expert knowledge.published_or_final_versio

    Conference Themes: Linking Knowing and Doing - Bridging the Gap between Theory and PracticeTeaching ill-structured problem solving skills is a critical and challenge task in medical education. While problem-base learning (PBL) is widely adopted in medical schools to enable students' learning with complex problems under minimal guidance, there are concerns about its effects on development of systemic knowledge structure and efficient reasoning process. To meet the challenge, a technology-enhanced learning environment is proposed in this study to improve students' expertise in complex problem solving by scaffolding their reasoning and knowledge construction processes with support of expert knowledge and model-based cognitive tools.published_or_final_versio

    A molecular dynamics model has been developed to investigate the effect of the crystallographic orientation on the material deformation behaviors in nano- indentation/scratching of BCC iron. Two cases with different substrate orientations have been simulated. The orientations along x, y and z direction are [001], [100] and [010] for Case I and [111], [-1-12] and [1-10] for Case II, respectively. Case I and Case II exhibit different deformation patterns in the substrate. During indentation, the pile-up can be observed in Case I, but not in Case II. During scratching the pile-up ahead of the movement of the indenter has been enlarged in Case I, while a chip with the disordered atoms is generated in Case II. It has been found that Case I has both higher hardness and larger coefficient of friction. The ratios of the hardness and the coefficient of friction between cases I and II are nearly 2. The reason is attributed to the different crystallographic orientations used in both cases

    Objective: To review the developments in human factors (HF)research on the challenges of health information technology(HIT) implementation and impact given the continuing incidenceof usability problems and unintended consequences from HITdevelopment and use.Methods: A search of PubMed/Medline and Web of Science®identified HF research published in 2015 and 2016. Electronichealth records (EHRs) and patient-centred HIT emerged assignificant foci of recent HF research. The authors selected prominentpapers highlighting ongoing HF and usability challenges inthese areas. This selective rather than systematic review of recentHF research highlights these key challenges and reflects on theirimplications on the future impact of HF research on HIT.Results: Research provides evidence of continued poor design,implementation, and usability of HIT, as well as technologyinducederrors and unintended consequences. The paperhighlights support for: (i) strengthening the evidence base on thebenefits of HF approaches; (ii) improving knowledge translationin the implementation of HF approaches during HIT design,implementation, and evaluation; (iii) increasing transparency,governance, and enforcement of HF best practices at all stages ofthe HIT system development life cycle.Discussion and Conclusion: HF and usability approaches are yetto become embedded as integral components of HIT development,implementation, and impact assessment. As HIT becomesever-more pervasive including with patients as end-users, thereis a need to expand our conceptualisation of the problems to beaddressed and the suite of tactics and strategies to be used tocalibrate our pro-active involvement in its improvement
