Design and Assessment for Hybrid Courses: Insights and Overviews
Technology is influencing education, providing new
delivery and assessment models. A combination between online and traditional course, the hybrid (blended) course, may present a solution with many benefits as it provides a gradual transition towards technology enabled education. This research work provides a set of definitions for several course delivery approaches, and evaluates five years of data from a course that has been converted from traditional face-to-face delivery, to hybrid delivery. The collected experimental data proves that the revised course, in the hybrid delivery mode, is at least as good, if not better, than it previously was and it provides some benefits in terms of student retention
Hybrid Course Delivery: Impact on Learning and Assessment
Technology is influencing education, blurring the boundaries of delivery modes. A combination between online and traditional teaching style, the hybrid/blended course, may present a solution with many benefits. This paper provides definitions of the different delivery approaches, and then evaluates four years of data from a course that has been converted from traditional face-to-face delivery, to a hybrid system. It is determined that the revised course, in hybrid delivery mode, is at least as good, if not better, than it previously was
Up-down symmetry of the turbulent transport of toroidal angular momentum in tokamaks
Two symmetries of the local nonlinear delta-f gyrokinetic system of equations
in tokamaks in the high flow regime are presented. The turbulent transport of
toroidal angular momentum changes sign under an up-down reflection of the
tokamak and a sign change of both the rotation and the rotation shear. Thus,
the turbulent transport of toroidal angular momentum must vanish for up-down
symmetric tokamaks in the absence of both rotation and rotation shear. This has
important implications for the modeling of spontaneous rotation.Comment: 15 pages, 2 figure
