currently taught with transmission-lines theory first, and the textbook is AppliedElectromagnetics by Ulaby3 et. al. Typical student at the beginning of this class does not have anyMatlab experience, has some understanding of vectors, very basic programming knowledge andalgorithms, some basic understanding of fundamental electromagnetic from a physics class andsome experience in linear algebra.During the course of the semester, students write their own Matlab codes to visualize static electricand magnetic fields, potential distributions and equipotential surfaces due to various line, surface,volume charge and current distributions using Green’s function integrals23. Wave propagation isintroduced through Matlab-based Graphical User Interface (GUI

inserted before the rising edge of the pulse.A survey is conducted after the internship to obtain the assessment of the project. The surveyincludes four questions that students were asked to rate their level of agreement with eachquestion in a five point scale (1 – Not at all useful; 2 – A little; 3 – Some; 4 – Quite a bit; 5 – Alot), and three questions that students were asked to write their comments. The survey isconducted anonymously so that students are able to express their opinions freely.Students in the internship program are very enthusiastic about the research, although they justfinished engineering preparation courses in the community college and are ready to transfer to afour-year college.

see not only the final ink on the page, butalso the order in which it was written.We compute numerical features from this digital record which characterize the vocabulary usedand the effort (time) expended, both in solving problems and writing self-explanation. Usingthese features we compute a statistical model which predicts students’ grades on varioushomework assignments. This model accounts for 32.9% of the variance in the students’performance. Furthermore, the underlying parameters of this model provide valuable insightsinto the ways students explain their own work, and the cognitive processes students employwhen asked to self-explain.2.

5 Stage Ring Oscillator Each inverter is composed of two Metal-Oxide Semiconductor Field-Effect Transistors(MOSFETS), which act as capacitors [1]. The inverter is the most fundamental construct ofdigital circuits. Its job is to take an incoming pulse and convert it to either high voltage or zero.This means that if a pulse has amplitude of 1.2V, the output of the inverter will be zero, or if thepulse has amplitude of zero, the output will be 1.2V. When the RO is started with alternating potentials of high and zero volts at nodesbetween inverters, the signal starts to oscillate. The signal frequency is dependent on thetransistor technology but most notably on the number of stages. Frequency and the number ofstages are inversely

locations. Steel structure design is one of the main approaches to thismission. Starting in the late 1800’s, steel became readily available for applications in large-scaleengineering structures. This triggered a tide of tall buildings, including the Home InsuranceBuilding in Chicago and the Manhattan Building in New York1. Steel frame buildings began torise all across the nation without any major changes in their connections or design for nearly acentury after the 1880’s. But after the structural failures during the 1994 Northridge Earthquake,there was a fundamental rethinking in the design of seismic resistant steel moment connections.This led to the SAC Steel Project research funded by FEMA2. The San Francisco Bay Regionexperienced large and

like increased knowledge andretention in programs2. Understanding concepts leads to growth throughout higher education, socare must be taken to guide the correct understanding of course material. If the student is to learnthe course material, he/she must understand the fundamentals and be able to apply them in futurecontexts.Active learning is used as a method to reach such aims. Student activity and engagement are keyelements of active learning2. This contrasts with traditional lecture formats, where studentspassively receive information from the professor. Through inquiry based learning, students canactively engage by performing experiments and by learning in teams.The reason for this study is to help students gain a greater understanding of
