Padlet:An online tool for learner engagement and collaboration

Extract:Padlet (previously known as Wallwisher) is a free Web 2.0 application that provides a virtual wall and collaborative space accessible from any Internet-enabled device. It is a live online bulletin board that has been described by its developers as “a living, breathing webpage” and “the easiest way to create and collaborate in the world.” Any number of participants can simultaneously view, add, and rearrange content on a Padlet, including text, images, and links to other web pages, videos, or documents. The bring-your-own-device application is easy for students to use and does not require an account or login to post on an existing Padlet. I consider myself technology-impaired, yet found it easy to teach myself to create and use Padlets to actively engage students at all points in the learning process. The biggest problem I faced was containing my enthusiasm and not over-using the technology

Boundary layer, skin friction, and boattail pressure measurements from the YF-12 airplane at Mach numbers up to 3

In-flight measurements of boundary layer and skin friction data were made on YF-12 airplanes for Mach numbers between 2.0 and 3.0. Boattail pressures were also obtained for Mach numbers between 0.7 and 3.0 with Reynolds numbers up to four hundred million. Boundary layer data measured along the lower fuselage centerline indicate local displacement and momentum thicknesses can be much larger than predicted. Skin friction coefficients measured at two of five lower fuselage stations were significantly less than predicted by flat plate theory. The presence of large differences between measured boattail pressure drag and values calculated by a potential flow solution indicates the presence of vortex effects on the upper boattail surface. At both subsonic and supersonic speeds, pressure drag on the longer of two boattail configurations was equal to or less than the pressure drag on the shorter configuration. At subsonic and transonic speeds, the difference in the drag coefficient was on the order of 0.0008 to 0.0010. In the supersonic cruise range, the difference in the drag coefficient was on the order of 0.002. Boattail drag coefficients are based on wing reference area

Why don't they learn?

[Extract] Highhouse (in press) suggests that managers’ “stubborn” preferences for suboptimal selection practices are based on two beliefs: 1) that selection decisions can be near 100% correct, and 2) that the expertise and intuition needed to make perfect decisions is developed by experience. I will suggest mechanisms by which these beliefs persist in the face of what should be contradictory feedback. When managers make selection decisions, they receive delayed and partial feedback on the correctness of their decisions. Often there is no feedback regarding candidates who are rejected, and managers probably assume that their decision to reject was correct. This creates a sizable set of apparently correct decisions that bolster the beliefs identified by Highhouse.For candidates who are hired, feedback may be delayed for a year or more until it is clear how well the new employee will perform. HR managers who are involved in a large number of selection decisions will not always receive feedback on the success or failure of each of the candidates they have helped to hire. Managers are more likely to become aware of the success or otherwise of individuals hired into their own units. However, the availability of feedback does not guarantee learning that selection is a probabilistic endeavour, or that intuition is a fallible basis for selection decisions
