Designing and developing a programme-focused assessment strategy: a case study

Abstract

This case study describes the process that the Humanities Programme Team, in Dublin City University’s Open Education Unit, has undertaken with regard to developing a systematic, programme-focused assessment strategy. It charts the development of an Assessment Matrix that facilitated the enhancement of programme coherence in the context of a distributed modular provision model, and facilitated the use of an appropriate range and scaffolding of assessment types in relation to learning outcomes. To conclude, four recommendations on developing a programme-focused assessment strategy are presented: explicitly link assessments to both programme and module learning outcomes; provide adequate supports and resources for those designing and writing assessments; provide those Assessment Writers with appropriate professional development, as well as an opportunity to be part of an assessment writing community; and to embed a programme-focused assessment strategy into a programme’s quality assurance processes.

Delay-dependent robust<Emphasis Type="Italic">H</Emphasis><Subscript>∞</Subscript> control for a class of uncertain switched systems with time delay

For linear switched system with both parameter uncertainties and time delay, a delay-dependent sufficient condition for the existence of a new robustH _∞ feedback controller was formulated in nonlinear matrix inequalities solvable by an LMI-based iterative algorithm. Compared with the conventional state-feedback controller, the proposed controller can achieve better robust control performance since the delayed state is utilized as additional feedback information and the parameters of the proposed controllers are changed synchronously with the dynamical characteristic of the system. This design method was also extended to the case where only delayed state is available for the controller. The example of balancing an inverted pendulum on a cart demonstrates the effectiveness and applicability of the proposed design methods.

Visualizing Matrix Multiplication

Efficient visualizations of computational algorithms are important tools for students, educators, and researchers. In this article, we point out an innovative visualization technique for matrix multiplication. This method differs from the standard, formal approach by using block matrices to make computations more visual. We find this method a helpful alternative for introducing matrix multiplication.
