, David K. Probst Department of Physics and Engineering Physics Southeast Missouri State University Cape Girardeau, MO 63701 AbstractMany concepts in physics and engineering courses cannot be understood easily. Althoughpowerful computers with advanced software can generate fancy animations, students still cannotgrasp these concepts without spending time reflecting on them. In the past, homework was thetool used by instructors to challenge students and enforce their learning. Unfortunately, nowmany students can bypass this challenge and directly go to the solution manual for answers,which is widely available from the

the antenna to vary. 2 We care about both the VSWR and the bandwidth because they tell us how our antenna will perform in the RF spectrum. VSWR is a measure of the reflected power from the antenna back to the hardware. The value is typically represented as a ratio of the max voltage in the line to the minimum voltage. Ideally, you would want a VSWR of 1, but any value below or around 2 is perfectly acceptable. When the VSWR becomes too high, on the order of 5 or so, the mismatch is too great to transmit signals over the antenna at that frequency. From the three design parameters we can calculate most characteristics of the

environment. When the lab environment is enjoyable, learning is accelerated.In Fig. 2 on statement 1, 44% of students were neutral and 38% agreed that the lectures wereuseful. This could signal that more demonstrations would be helpful. On statement 2, while 25%of the students strongly agreed on the usefulness of the lab instructions, 31% equally mentionedas agree or neutral. This somewhat reflects our objective of having minimal “recipe” instructionsthat require significant student attention. Statement 3 on interactive learning and discussionsduring the lab, students strongly agreed and agreed by 63% and 31%, respectively. Indeed, this isgreat news. For statement 4, 38% of students responded as strongly agree and 50% of students asagree about their

topic.Overall, students were observed to place more care in their experiments than they had in the past.This was especially evident in the final projects, where students took great care to minimizefluctuations in their system’s outputs. Accordingly, average final project scores were a half-letter grade higher than in past semesters (28 students each term; same instructor), reflecting thisincreased care and professionalism. For example, a group optimizing a paper airplane designselected heavy paper as it was found to lead to less fluttering; another group carefully designedtheir “bottle flip” experiment to minimize the human error; another meticulously determined arepeatable condition to test soap bubble lifetime. It is believed the new randomization

indicates that the cart was traveling at a speed of 0.017 cm/µs. Most groups will use theraw data as reported in centimeters and microseconds. When asked, students are satisfied with thesmall number that they determine for the speed. It is considered as a reasonable result until it is Figure 3: The header comment to the starter sketch controlling the Vernier Motion Detector.converted to 170 m/s, or half the speed of sound used in the sketch. The fact the 90% of labgroups report this result without reservation initially reflects student willingness to accept theresults that the computer reports with little critical evaluation. This leads to a discussion abouthow to modify the program to report the time that the cart is at each position and not the

Below, we provide a summary of the questions asked to the MLM groups, withthe initial conclusions drawn by the authors. It is important to stress once more that theseresults are only reflective of the groups who used the MLM in the fall semester due totime constraints.Question 1: “What was your opinion on the effectiveness of the FlipIt Physics product?”Sample Positives • “I think the success I had in this class can be attributed to how prepared I was for the lectures.” • “I really enjoyed Flipit physics it kept me organized and helped me understand.”Sample

of two entangled beams of photons aimed at asubstance and measure the interference pattern in the reflected beams. The use of entanglementsignificantly increases the information content gathered as the measurement of one photon willgive you information about the other. This technology has a great potential in medical use wherenon-invasive, real-time imaging of a living organism is desirable. [17] Similar techniques inastronomy are expected to improve the performance of interferometers in astronomy. Forinstance, while LIGO finally detected gravitational waves from colliding black holes in 2015using Michelson interferometers, entanglement enhanced interferometry can help detect weakergravitational waves.

activities to develop students’ reasoning skills and therefore, increase engineeringstudents’ physics learning.IntroductionScientific reasoning refers to “cognitive abilities such as critical thinking and reasoning” (Bao etal, 2009, p. 586) or “skills involved in inquiry, experimentation, evidence evaluation, andinference that are done in the service of conceptual change or scientific understanding”(Zimmerman, 2007). It is needed in problem solving situations and requires methods of scientificinquiry such as the cycle of analysis, testing, reflection and revision, in order to construct adeeper understanding of the situation. Scientific thinking is “purposeful thinking that has theobjective of enhancing the seeker’s knowledge” (Kuhn, 2010, p. 2).To
