Evaluation of the Accessibility of Engineering Vocabulary Chirag Variawa and Susan McCahan University of TorontoAbstract:Do engineering instructional materials at the university level contain identifiable barriers tosuccess unrelated to course objectives? This is a growing concern as the population of studentsbecomes more diverse. And if there are barriers, how prevalent is this issue and can thesebarriers be characterized in a way that allows the instructor to easily identify and remove ormitigate them? In response to these questions, a research study is being conducted to at theUniversity of Toronto to look at the accessibility of the language used on

So, this begsthe question, why are there so few electronic books in use in higher education? In part, this isbecause many of the commercial books are not available electronically. Although some publishersare exploring ways to make their collections available electronically these efforts are still in theirinfancy.However, a larger puzzle is in the step away from paper to purely electronic media. For example,consider the following problems. How do you write notes or slip a page into a fixed PDF file? Isthe document you are viewing on your machine or on the network? Who can

Studio format is a method of teaching engineeringmaterial, using cooperative learning and hands on activities. This course is a requirement for allof our electrical engineering and computer engineering undergraduate students. The coursepreviously did not have laboratory content and in expanding the course we chose studio as analternative to laboratory format. Unlike other uses of studio format, the lecture component wasretained as-is. In this case studio is scheduled separately

Such a multi-disciplinary discussion of this problem is expected to educate ourstudents and prepare them to manage diversity in their future careers. There are three key components ofthis discussion.
