Characteristics such as poorteaching or organization of material, hard or confusing material, loss of confidence inability to do science, cut-throat competition in assessment systems or “weed out”philosophies, dull subject matter, and grading systems that did not reflect what studentsfelt they had accomplished were reasons given by females for leaving SME majors. Thecompetitive atmosphere, the grading system, and the dullness of subject matter was muchless troubling for males in the same study. These findings illustrate discouraging factorsfor retention related to classroom climate and activities and

There are different areas ofengineering but the field is not as broad from “an information about careers” perspective astechnology. In the technology sections while we likewise want to engage and excite them aboutthe technology majors, we offer a variety of different degree programs and need to include themall. In engineering we direct students to explore the web sites of the various engineeringprofessional societies and ask that they write a short reflection about what they found interesting.There are not the same types of opportunities for all of the technology majors.

It is not a question of who the better instructor was butit is a question of who the students would have wanted to learn from. The inference is that thepracticing engineers turned clinical adjunct faculty can build student interest in the subject, andcan provide beneficial interests in terms of student learning. The departments that attract thesekinds of adjunct faculty also benefit because it builds their reputation.It is interesting to note that the Chronicle of Higher Education reported that “nearly half ofundergraduate courses are taught by non-tenure-track instructors.”1 The article goes on to

Depending on the agreement,some of the resources may come from the university, and others will either be donated by industrypartners, or purchased by using the interest generated by the established endowment. A critical phase ofthe laboratory development is the selection of equipment that reflects the needs of the students andindustry partners. A significant effort is put on identifying the most relevant hardware and laboratoryexercises to make sure the students get the most up to date equipment and training. Proper coordination isrequired to make sure the hardware arrives in timely fashion and

Since the jumping movement is mainly in the vertical axis, theacceleration over z-axis depicts the pattern more clearly. We also calculated the normalizedmagnitude value (Anorm) using Equation (1) and setting T=0.5sec. The change of Anorm over timeis plotted in Figure 7(b), showing that Anorm does reflect the level of activity. For example, Anormis higher during the jumps, but lower while standing.We also tested an abnormal movement where a person falls on the ground.

In spite of such issues, the analysis of in vivo time series data is veryuseful in gauging the response of in vivo systems that have not undergone artificial isolation andpurification. In particular, such data accurately reflect the activity of cells and organisms andhow they respond to signals and stimuli. Living organisms must coordinate biological machineryacross several levels of organization, from gene expression to dynamic changes in proteinabundance to adaptive changes in metabolic profiles and physiological response. These changescannot always be deduced from in vitro measurements of rate constants and

One development that they made was Concentrated Solar power. In solar energy, panels are typically placed at certain angles to obtain the best sunlight. However, in concentrated solar, solar panels are strategically placed to obtain the most amount of sunlight while still reflecting the light to a single tower that gathers all the light in. This single tower then transmits the energy to a water depot and the heat vaporizes the water, creating high-pressure steam. This high-pressure steam then enters a turbine, which

(9)The large variation in PBL practicesmakes the analysis of its effectiveness a bit complex. Many studies comparing PBL to traditionalprograms are simply not talking about the same thing. As reported by Prince(9), “ For meta-studies of PBL, to show any significant effect compared to traditional programs, the signal fromthe common elements of PBL would have to be greater than the noise produced by differences inthe implementation of both PBL and traditional curricula
