readings. Black horizon- tal line segments are averages over time widows corresponding to steady state operation.Table 2: Sample steady-state results. The Q row is computed with Equations (1) and (2) using Vin = 12V and R = 5.4 Ω for heat sink E, and p values from the PWMheat row of this table. Values of Tave are obtained by averaging over the horizontal plateaus of the data in Figure 12.

andquiescent (Q) point was described with a four-resistor bias network. The lab exercise for thatday was to build a biasing network and measure the voltages and currents and set the Q-point forthe transistor. The next section discussed the MOSFET as an amplifier and the idea of usingcapacitors to block DC voltages while passing AC signals in and out for amplification. Thestudents then added the appropriate capacitors to their circuit and measured the AC voltage gainat a fixed frequency. The last segment discussed the coupling capacitors and bias network ashigh-pass filters on the input and output. The students then measured the frequency response ofthe amplifier and compared it to expectations for the combined high-pass filters. Results

courses, the students were overwhelmed at the end of the semester and had trouble putting in the time to do a good job on the project. Also, the pipe task was too difficult, it should be cut down to just finding Q given 𝛥P for straight pipes.3. AssessmentAssessment was implemented via student grades, student surveys, and, for 2014 and 2015, a popquiz given on the last day of class.3.1 Percentage of Report Grades Below 75%In 2010 - 2013, 27% of the lab reports received grades below 75%. In 2014, 5% of the pre-labs(which contained most of the material) and 5% of the post-labs (which required minimal work)were below 75%. This was expected since the students had to keep reworking all of the pre-labmaterial until it was correct, and

tohave a better learning experience, some of the answers from the students include the following:  “The lab instructions were very detailed until the end. However, the part where we had to graph the I and Q components of the signal was not clear. Lab procedures could be improved.”  “Manual is too long. For pre-lab part, it does not clearly state what is expected from us, which makes us struggle much more than required to learn.”  “Better introduction to LabVIEW and the USRP (is needed)”.  “Since LabVIEW is new to many of us, it would be greatly helpful if the lab process were taken step-by-step. Perhaps we can start with an easy example, such as an AM Demodulator and understand what is happening in the process in

experiment with actual experimental results. 3. Demonstrate the beginnings of professional practice: a. Effectively communicate in written form the design, completion, and analysis of experiments to answer open-ended questions. b. Effectively communicate by oral presentation and Q-and-A session the design, completion, and analysis of experiments to answer open-ended questions.We have assessed these objectives with both direct and indirect measures since the beginning ofthe course. A full discussion of the objectives, assessment, and changes to the course far exceedsthe scope of this paper. For this paper we are focused on Objectives 1b (data acquisition), 2a(design & complete experiments), and 2c (compare
