of Learning Gains. Preliminaryanalysis of data from the MCI for a portion of the control group shows that there are significantgains in learning even in a traditional lecture class, and that the MCI appears to have some biasagainst women.IntroductionTraditional models of teaching are focused on the delivery of content. It is assumed that learningoccurs by the instructor telling the students the information. The problem with this approach isthat it does not match with the research on learning. The well-known cognitive model oflearning, developed in the field of psychology, describes the processes by which a learneracquires new information.1 Figure 1 illustrates this model. The key point to note in this model isthat information is actively

We feel that using CPR to facilitate the peer evaluation process is aneffective way to enhance undergraduate engineering students’ technical critiquing skills.Introduction to Calibrated Peer Review™ (CPR)Developed at UCLA in 1995, CPR promotes active learning through writing and models the peerreview process in science and engineering disciplines (http://cpr.molsci.ucla.edu). The NationalScience Foundation and the Howard Hughes Medical Institute provided initial funding for CPR,and it has been used at over 500 academic institutions.1

It is estimated that at least 84 majors consider thespatial visualization a fundamental need (Smith, 1964) and in technical jobs, such as thedifferent types of engineering, the abilities to visualize are especially important (Maier,1994)2.The third reason that justifies this study is that educators need to continually analyze andinvestigate their own teaching to be more effective educators (Fernando Hernandez,1992) 3.Previous analysis and current situationThe visualization of parts in the multiview projections system, in other words, theinterpretation of views of an object represented by its technical drawing, is

piqued a few years ago when a group of seniordesign students who had taken my course began working with an extension colleague on aproject involving the estimation of average annual erosion from an agricultural field. Threestudents computed three very different estimates and the variation was due to differences in theway one selects the length factor. As the instructor of the Introduction to Natural ResourcesEngineering course where the students would be expected to learn how to use the USLE, thiscaused some consternation and reflection. I asked this colleague how he would have made thecalculation, and saw quickly how students could get different answers for a typical field asshown in Figure 1.Figure 1. Typical slope lengths.

Here again burning natural gas isattractive, because the hydrogen to carbon ratio is 4:1 as compared to roughly 2:1 for liquidfuels. Finally, the combustion of natural gas produces little or no particulates.Based on the considerations mentioned above, a combined gas and steam (COGAS) propulsionsystem is a very promising alternative to steam or diesel propulsion. It is therefore appropriatefor the marine engineering designers of the future to be familiar with this approach.Structure of the courseThe course has thermodynamics and fluid mechanics as prerequisites.

I remember telling my mother after I receivedmy first quarter grades that if I didn’t do better the next term, I was going to leave. Several factors werecontributing to this resolve: 1) I did not want to suffer the embarrassment; 2) I did not want to disappointmy family who went around bragging about me to everyone; 3) I had not made any friends yet and I washomesick; and 4) the place was just too BIG.

curricula include chapters ormodules on decision analysis, and decision trees are often introduced and promoted as a decisionmaking tool. The teaching of value of information (VOI) analysis within the decision analysisframe is less prevalent, notwithstanding the variety of potential applications to everydaydecisions in engineering practice. This paper seeks to remedy this gap by providing an accessibledemonstration of how decision trees can be used to teach important VOI concepts, including ananalysis of the role of risk preferences.It is often most efficient to set up and solve VOI problems in a generalized analytical framework,and this is often the approach taken in applied research.1-3 But analytical representations of VOIproblems are not

Effectivenessof simulation-based learning is well recognized. Edgar Dale’s cone of learning as shown inFigure-1 supports the benefits of simulation based learning. According to the Encyclopedia ofEducational Technology1, "Simulation-based learning involves the placement of a student into arealistic scenario or situation. The student is then responsible for any changes that occur as aresult of their decisions." Educators have been designing, using, evaluating and writing about simulations for morethan 45 years.

Determine the purpose of the evaluation; 2. Define the aspects/dimensions of teaching to be evaluated; 3. Identify valid sources of data or evidence for each aspect of teaching being evaluated; 4. Specify the criteria, or measuring instrument, by which the aspects will be judged; 5. Analysis and interpretation of data by skilled, trained personnel; and 6.
