Assessment Practices using Online Tools in Undergraduate Programs

Abstract

This chapter provides an overview of the use of online and Web-based learning technologies as formative and summative assessment. Peer learning and assessment, provision of feedback to students, online tests and quizzes, plagiarism detection systems, and audience response systems are all examined with a view to highlighting best practice and demonstrating that online assessment must still follow sound pedagogy to be both valid and valued by instructors and students alike.

Analysis of Bifurcations in a Wind Turbine System Based on DFIG

“…The bifurcation theory provides a set of mathematical techniques and related analysis for nonlinear Differential Algebraic Equations (DAEs). In particular, the bifurcation theory is widely recognized as an effective tool to study voltage stability [10][11][12][13]. The advantage of this technique consists in the determination of the system eigenvalues, i.e., it is not necessary to numerically solve the Jacobean matrix for the system, thus significantly reducing the computational effort and providing a qualitative tool to assess nonlinear oscillation in nonlinear power grid dynamical system.…”
