Engineering education has been slow to adopt research-based educational innovations. Few prior works on such adoption have investigated the combined classroom experiences of instructors and students when such innovations are being implemented. Therefore, this work focuses on the lived experiences of an instructor and her students when adopting an active, blended, and collaborative learning environment, known as Freeform, in a second-year dynamics course. Weekly reflections from the instructor were processed alongside student interviews using Thematic Analysis to discern prominent themes in their perspectives for comparison and discussion. The results indicate that the instructor navigated internal tensions between her previous instructional preferences and the philosophy and resources of Freeform. Similarly, students had to adapt to this new philosophy and suite of resources that were uncommon for their institution. Ultimately, this work highlights the contextual natures of teaching and learning, and how situational factors can influence educational innovation.  相似文献   

Perceptions of optimal conditions for teaching and learning: a case study from Flinders University

Effective teaching and learning in higher education is an important focal point of literature around the globe. Various models are presented as desirable and fostering optimal conditions for teaching and learning. However, each model must be examined within the context of its institutional culture, mission and strategic plan to ascertain if it meets the envisaged goals. The Reinventing Teaching Project survey conducted at Flinders University in 2009 provided a unique opportunity for academic staff and students across all faculties to respond to a survey that explored their perceptions of optimal learning conditions and assessed if the campus environment was conducive to effective teaching and learning practices. The exploratory study was designed to gather qualitative and quantitative data on the motivation of teachers and learners to engage with learning and learners (or not). The results of the survey present valuable insights into what teachers and learners consider to be important attributes of optimal teaching and learning and indicate a number of similarities and differences among teacher-student perceptions. This paper identifies and discusses some of the pertinent outcomes of the study to provide a framework for other similar studies.  相似文献   

Kinematic optimization of 2D plunging airfoil motion using the response surface methodology

The propulsive efficiency of a plunging NACA0012 airfoil is maximized by means of a simple numerical optimization method based on the response surface methodology (RSM). The control parameters are the amplitude and the reduced frequency of the harmonic sinusoidal motion. The 2D unsteady laminar flow around the plunging airfoil is computed by solving the Navier-Stokes equations for three Reynolds number values (Re = 3.3×10³, 1.1×10⁴, and 2.2×10⁴). The Nelder-Mead algorithm is used to find the best control parameters leading to the optimal propulsive efficiency over the constructed response surfaces. It is found that, for a given efficiency level and regardless of the considered Re value, it is possible either to obtain high thrust by selecting a high oscillation frequency or to reduce the input power by adopting a low plunging amplitude.  相似文献   

The freedoms of software and its ethical uses     

Samir Chopra  Scott Dexter 《Ethics and Information Technology》2009,11(4):287-297

The “free” in “free software” refers to a cluster of four specific freedoms identified by the Free Software Definition. The first freedom, termed “Freedom Zero,” intends to protect the right of the user to deploy software in whatever fashion, towards whatever end, he or she sees fit. But software may be used to achieve ethically questionable ends. This highlights a tension in the provision of software freedoms: while the definition explicitly forbids direct restrictions on users’ freedoms, it does not address other means by which software may indirectly restrict freedoms. In particular, ethically-inflected debate has featured prominently in the discussion of restrictions on digital rights management and privacy-violating code in version 3 of the GPL (GPLv3). The discussion of this proposed language revealed the spectrum of ethical positions and valuations held by members of the free software community. In our analysis, we will provide arguments for upholding Freedom Zero; we embed the problem of possible uses of software in the broader context of the uses of scientific knowledge, and go on to argue that the provision of Freedom Zero mitigates against too great a moral burden—of anticipating possible uses of software—being placed on the programmer and that, most importantly, it facilitates deliberative discourse in the free software community.  相似文献

A Multicomponent Library Resource Model to Enhance Academic Global Health Education Among Residency Programs     

Rupa R. Patel  Sandhiya Ravichandran  Michelle M. Doering  Angela C. Hardi 《Medical reference services quarterly》2017,36(2):120-128

Global health is becoming an increasingly important component of medical education. Medical libraries have an opportunity to assist global health residents with their information needs, but first it is important to identify what those needs are and how best they can be addressed. This article reports a collaboration between global health faculty and an academic medical librarian to assess the information needs of global health pathway residents and how assessment data are used to create a multicomponent program designed to enhance global health education.  相似文献
