During the past two years, computer-based tutorials were developed and evaluated as instructional tools in biochemistry and medicinal chemistry courses. The tutorials, which review and encourage application of key concepts within these subject areas, were developed using the authoring software program ToolBook. The tutorials are tailored to the instructor’s courses and allow students to work at...

End-user authored tutorials are increasingly becoming the norm for assisting users with learning software applications, but little is known about the quality of these tutorials. Using metrics derived from previous work, I characterize the quality of textand image-based Photoshop tutorials available to users online. I compare these tutorials across four sources representing tutorials that are, i...

The Web is replete with tutorial-style content on how to accomplish programming tasks. Unfortunately, even top-ranked tutorials suffer from severe security vulnerabilities, such as cross-site scripting (XSS), and SQL injection (SQLi). Assuming that these tutorials influence real-world software development, we hypothesize that code snippets from popular tutorials can be used to bootstrap vulnera...

The development of an automatic speech recognizer is typically a highly supervised process involving the specification of phonetic inventories, lexicons, acoustic and language models, along with annotated training corpora. Although some model parameters may be modified via adaptation, the overall structure of the speech recognizer remains relatively static. While this approach has been effectiv...

1.1. Why is Algebraic Geometry Beautiful. We begin with problem number two on the homework which asks us to find 27 lines on the cubic x+y+z+1 = 0. This leads us to the following beautiful story of algebraic geometry. Every cubic in P (you can think of this as A if you want) contains exactly 27 lines. In fact, since the variety of lines in P is simple to understand (it is just the Grassmanian) ...

We consider student use and perception of video tutorials that were produced to serve as virtual office hours for an undergraduate Operations Research (OR) course. The video tutorials complemented the traditional classroom experience by offering different example applications, presentations of solution methods, and examples for different cases of an OR problem (e.g., maximize versus minimize ob...

Human–machine-interaction studies complex communication and interaction principles between people and computers. HMI research is concerned with a wide field of related topcis covering the realisation, evaluation of interactive machine and computing systems. It furthermore covers knowledge representation, displaying techniques, signal processing, pattern recognition, human factors, haptics and r...
