SystemWe also have a mass that consist of several squares of aluminum. With this particular mass wecan show the effects of viscous damping by using squares of different sizes. When the largersquares are used it is obvious that there is more viscous damping as the mass stops vibrating a lotsooner than when only smaller squares are used. As one can see from the picture below we caneasily interchange the metal squares. This allows us to do several different cases quite quickly.This setup also allows us to set up a project where the students try to actually calculate thedamping coefficient for the spring mass system. The students are given the apparatus shownabove and a two meter stick. Their job is to find the spring constant for the spring, weight

The questions for these surveys mainlyfocused on students’ prior knowledge of iron and steel science and industry, as well astheir interest in them. Two questions given in the first survey were: Do you know of any steel plants in the area or in the U.S., and can you describe any of the products that they make? In 1-2 sentences, describe your impressions of the steel industry.Two questions from the second survey were: Did the presentation pique your interest in any particular area of ferrous materials engineering, e.g. processing, property testing, or

Stiffness and maxi-mum stress of the perforated beam are compared to the corresponding values for a beam withoutholes obtained from conventional beam theory. Students experiment with a brute force method ofmeshing around the holes by starting with a finite element mesh of the solid beam and then cal-culating the distance from the center of each circle to the midpoint of all elements. Only thoseelements are retained in the analysis whose midpoint lies outside of all circles. If the finite ele-ment mesh is fine, this extraordinary simple and efficient procedure, which constitutes a particu-lar highlight of this project, approximates the circles well (see Fig. 3).

One framework for such decision-making is establishingwhether the condition represents an isolated incident, a pattern-of-behavior, or a systemicproblem.An isolated incident is typically a one-time occurrence, and may be either a mistake orintentional. An example of an isolated incident would be a student on a rare occasion arriving toclass late. A Pattern-of-behavior is defined as repeated offences, usually with increasinglynegative impacts on the student or others. As example of a pattern-of-behavior would be astudent’s inability to get along with classmates on project work teams in several classes. Finally,a systemic problem is manifested in

The effectiveness of these measures is often studiedwith the most emphasis placed on the validity and reliability of the statistical reporting.Determining validity is difficult and since most professors who create these measures are nottesting experts, a practical approach is to use content validity (content represents an adequatesampling of what was taught). The difficulty of the questions is of concern as well, for as Stennerpointed out, “If you don’t know why this question is harder than that one, then you don’t knowwhat you are measuring.”9 By looking at the difficulty of exam questions, you should be able todevelop questions of higher content
