As a result of their different sizes, the indium phosphide quantum dotsstudied (which we obtained from CENCO Physics) emit light of different wavelength whenexcited by ultraviolet light. In addition to being size dependent, the energy gap also depends ontemperature. In the experiment, the quantum dots are exposed to different temperatures and, byusing a spectrometer, the wavelengths at which they emit light when excited by an ultravioletsource are recorded and compared.

And, in general, this approach Page 26.1357.2serves the students well through their undergraduate education process and in their industrialcareers – as long as they remain specialized in their specific engineering discipline.However, consider the case where

Note that the device is not drawn to scale.The mathematical description of the conduction of electrons and holes in a polymer film iscomplicated; the material is not crystalline so the concept of energy bands loses validity. Thetheoretical treatment is similar to that used for disordered or amorphous materials; the disorderpresent in the polymer causes the creation of localized energy states and conduction occurs via ahopping (quantum mechanical tunneling) process.18,19,20 Electrons in

assumptions.Predictions support experimentation; they are the hypotheses of experiments. Engineers regularlymake predictions about the effects of interventions. Scientific predictions are empirically testedfor their validity. Predictions assume a deterministic relationship between cause and effect, thatis, that forces in the cause reliably determine an effect. In his Metaphysics, Aristotle argued thateverything is determined by material causes, formal causes, efficient causes, and final causes(purpose of thing)3.ImplicationsA less deterministic form of prediction is to draw implications from a set of conditions or statesbased upon plausible cause-effect relationships. To imply is to entail or entangle events or toinvolve an effect as a necessary consequence of

As part of the administration of the course, there were local facultymembers at each participating institution who were assigned to facilitate local logistics. One oftheir primary tasks was to administer the exams in a proctored environment if desired by thefaculty member teaching the course. They also submitted final grades for the local students.One unanticipated challenge was that the semester schedules did not align across all institutions,but that was relatively easy to accommodate.Course DescriptionThe course discussed here is a typical, upper-level physical optics course that uses the textbookOptics, by Eugene Hecht.

Documentation of evidence includes but is not limited to exams, homework, grading rubrics for written/oral communications, research papers, etc. When evidence is in the form of student work samples, a representative sample of the class performance should also be kept (e.g. one or two high, medium, and low graded samples). During Self-Study years, the evidence in the form of student work samples is copied and filed under the respective outcome; during non self-study years evidence forms are sufficient and only capstone material is preserved.

physics education has matured and grown. A reasonablycomprehensive description of the state of the field can be found elsewhere 1. The process ofidentifying misconceptions, creating curricula to address those misconceptions and then evaluatingthe efficacy of instruction has been applied to many areas of physics 2, perhaps nowhere moresuccessfully than mechanics. In that arena, many well-validated and established instruments exist,including the Mechanics Baseline Test 3, Test of Understanding Graphics in Kinematics (TUG-K)4 Page 24.34.2and the Force Concept Inventory5 to name but a few.

In thispaper, we describe the development of a sophomore-level Applications of Modern Physicscourse that bridges the lower-level and upper-level curriculum for electrical engineering andphysics students. The course starts from the atom and quantum mechanics, building up to nano-scale systems, and finally solids and devices
. Something that they could have done to increase the reliability is to use something other than legos to release the ball down the tube. Some solutions to these problems could be to use a different material or method to pull out the block. One material that would be good is a metal or some other material that had a smooth surface to reduce the friction. Another way to increase the reliability would be to somehow drill the mechanism to the tube or tape it more securely. This would make it more stable so that when the weight drops on the lever and pulls the string the string wouldn’t pull the mechanism off the tube. All of these ideas could be very beneficial because as I watched this stage it was very hard to operate and reset. Student 2: The least

courses are the key gateway courses in engineering. Most engineeringstudents take one year of physics courses. The first semester materials cover mechanics basedphysics, which are taught in great detail at several high schools, but the second semester ofphysics, electricity and magnetism are somewhat new to several students. Motivating students tolearn these concepts individualistically in addition to the materials covered in class is achallenging task. One way to deal with this issue is to assign a design project as part of thecourse requirement. In this effort, students were given a team project to design and build anelectric motor and optimize its performance. Converting electrical energy to mechanical, andmechanical energy to electrical in

Final exam results showed that the MSP group mean was higher(M=67.4, SD=15.7, N=151) than that for the LRE group (M=60.6, SD=17.5, N=160)(t(309)=2.179, p<0.001). At-risk students in the MSP course also performed better than acomparative group in the LRE course. Pre- and post-course written surveys revealed that theMSP group’s mean confidence in physics skills was higher than LRE group mean by the end ofcourse. Observations and student and teaching assistant interviews about student study processeshighlighted a greater prevalence of “deep learning” and “strategic learning” strategies used bythe MSP group compared to the LRE group.I.

Tobias [25] also indicatesthat writing can serve as a means to help students relieve their anxiety as well as help themunlearn models and techniques that have been shown to be scientifically unsound. Using a writing approach to assist students in the learning process can provide a wealthof qualitative information while the actual learning is taking place. Traditional tests and quizzesmerely provide an assessment marker after a segment of material has been provided in class.While important as a marker for charting process, these forms of assessment do little to uncoverwhat is

As a result of our assessment effortswe have been able to expand our physics program by adding the following upper-level courses: Astrophysics Mathematical and Computational Physics Physics Capstone Seminar Statistical Mechanics Waves and OpticsPrior to 2007, the physics program included two “tracks” that students could follow as theyprogressed through the curriculum. These tracks were in computational and applied physics.Since our initial assessment, we’ve added a traditional physics track and the applied physicstrack is now a track in chemical physics.

For several years the physics course was based on a traditionalintroductory college mechanics laboratory curriculum. This curriculum was not inquiry-basedand provided only limited opportunities for students to construct their own knowledge byperforming open-ended activities.Scholarly research into the teaching and, more importantly, the learning of physics has providedvaluable guidance for the design of innovative curricula and pedagogy 1 .
