Serious games in favour of knowledge management and double-loop learning?     

David?Vallat  Caroline?Bayart  Sandra?BertezeneEmail author 《知识管理研究与实践》2016,14(4):470-477

How can universities develop a knowledge management dynamic in order to train knowledge workers who are effective in an organizational learning process? Can games, and more specifically serious games, contribute to reaching this goal? To answer this question, we hypothesize that play can serve as a lever for knowledge management and double-loop learning. The purpose of this article is to show that serious games contribute to training knowledge workers in an organizational learning process. From this perspective, we attempt to understand how serious games promote the acquisition of knowledge and we explain the research method used in the field (participant observation, investigation using questionnaires). The final part analyses the main results: a community of practice and organization learning, internalization through Learning by Doing and better understanding of the environment’s complexity, towards double-loop learning and student satisfaction with the serious game.  相似文献   

Open source software development—Just another case of collective invention?     

Margit Osterloh  Sandra Rota 《Research Policy》2007,36(2):157-171

Do open source software (OSS) projects represent a new innovation model? Under what conditions can it be employed in other contexts? “Collective invention” regimes usually ended when a dominant design emerged. This is not the case with OSS. Firstly, the OSS community developed the institutional innovation of OSS licenses enabling OSS software to survive as a common property. Secondly, these licenses are mainly enforced by pro-socially motivated contributors. We characterize the conditions under which OSS communities develop and sustain pro-social commitments. We point out the vulnerability of these conditions to developments in patent legislation.  相似文献

Microfluidic model of monocyte extravasation reveals the role of hemodynamics and subendothelial matrix mechanics in regulating endothelial integrity     

Sandra Prez-Rodríguez  Stephanie A. Huang  Carlos Borau  Jos Manuel García-Aznar  William J. Polacheck 《Biomicrofluidics》2021,15(5)

Extravasation of circulating cells is an essential process that governs tissue inflammation and the body''s response to pathogenic infection. To initiate anti-inflammatory and phagocytic functions within tissues, immune cells must cross the vascular endothelial barrier from the vessel lumen to the subluminal extracellular matrix. In this work, we present a microfluidic approach that enables the recreation of a three-dimensional, perfused endothelial vessel formed by human endothelial cells embedded within a collagen-rich matrix. Monocytes are introduced into the vessel perfusate, and we investigate the role of luminal flow and collagen concentration on extravasation. In vessels conditioned with the flow, increased monocyte adhesion to the vascular wall was observed, though fewer monocytes extravasated to the collagen hydrogel. Our results suggest that the lower rates of extravasation are due to the increased vessel integrity and reduced permeability of the endothelial monolayer. We further demonstrate that vascular permeability is a function of collagen hydrogel mass concentration, with increased collagen concentrations leading to elevated vascular permeability and increased extravasation. Collectively, our results demonstrate that extravasation of monocytes is highly regulated by the structural integrity of the endothelial monolayer. The microfluidic approach developed here allows for the dissection of the relative contributions of these cues to further understand the key governing processes that regulate circulating cell extravasation and inflammation.  相似文献

Exploring pedagogical content knowledge of biology graduate teaching assistants through their participation in lesson study     

Sandra A. Lampley  Grant E. Gardner  Angela T. Barlow 《Teaching in Higher Education》2018,23(4):468-487

Graduate teaching assistants (GTAs) are responsible for teaching the majority of biology undergraduate laboratory sections, although many feel underprepared to do so. This study explored the impact of biology GTA participation in a professional development model known as lesson study. Using a case study methodology with multiple qualitative data sources, this study found that lesson study was beneficial for this group of GTAs in that it modified critical aspects of their beliefs about biology instruction. Each participant felt that lesson study helped revise their teaching and changes were seen in some aspects of the participants’ Pedagogical Content Knowledge (PCK). Despite this, there was an observed disconnect between participants’ vocalized intent and classroom practice. This disconnect could be attributed to the difficulty of implementing new strategies, the short duration of the lesson study, and the instructional inexperience of the participants in the study.  相似文献   

Feeling the forces within materials: bringing inter-molecular bonding to the fore using embodied modelling     

Elon Langbeheim  Sharona T. Levy 《International Journal of Science Education》2018,40(13):1567-1586

We developed a computerised simulation that utilises embodied modelling by letting students play the role of particles in a liquid. We compared the learning of two eight-grade classrooms that used the embodied modelling simulation during a weeklong learning module on phase change, with a comparison group that used an ordinary simulation with no embodied modelling. In the pre-test, neither group mentioned inter-molecular forces in their explanations. In the post-test, significantly more students from the embodied modelling group mentioned inter-molecular bonds in their explanations than their counterparts who used the regular simulation, and realised that inter-molecular forces influence the motion of particles. However, we found little difference between the groups in students’ ability to relate the magnitude of the inter-molecular forces to the magnitude of the boiling point of the material, showing not only the potential but also the limits in developing complex conceptualisations through this approach. Building on these findings, we discuss the affordances of embodied modelling for learning complex models, and suggest future directions for research into embodied modelling.  相似文献   

Reflection and its Place in the Curriculum on an Undergraduate Course: Should it be assessed?     

Sandra Stewart  Barbara Richardson 《Assessment & Evaluation in Higher Education》2000,25(4):369-380

In the fast changing world of health care the need for therapists to be reflective practitioners is no longer disputed. How reflection is taught and assessed at undergraduate level is however more contentious. This longitudinal study explores the experiences of students undergoing a number of assessments of reflection and also examines whether members of faculty have similar perceptions of those assessments. Analysis of data from focus groups and individual interviews suggest that students have a number of concerns about the assessment of reflection, some of which are shared by faculty. The paper concludes that the process of reflection is better left unassessed.  相似文献
