Our data analysis process was an iterative one involving continualexamination and discussion. Interview data were analyzed using constant comparativemethods of analysis17. In the first phase of analysis, the students’ interview responses weretranscribed from both audio and video records. The research team looked for patterns instudents’ responses that reflected their subjective reasoning. Each of the first two authorsindividually identified and grouped distinct responses. The grouped categories were used tostructurally describe participants’ reflections on their learning
choices in this survey, we only use responseswith indications of either “very much” or “not much” when we define the majority in Figures 1and 2, respectively. The same definition of “majority” is applied to both Figures 3 and 4. Figure 1 and Table (II) display the 13 questions that produced a relatively higherpercentage of “desirable answers”. As illustrated in Figure 1, most survey questions/statementsthat received "desirable" responses generally mirror students’ learning experiences and thus theseresults are quite understandable. For example, students’ responses to statements under thecategory of “Effort”, (e.g., E20, E21, E22, E23, E24) typically reflect their strong determinationto learn well. Three questions in the category of
. While females haveslightly higher mean grades and higher mean GPAs in the course, they have significantly lowerFCI gains than their male constituents. If course grade can be taken to reflect how much astudent has learned, and GPA as a measure of academic success, then it would be reasonable tothink that the female students would have slightly higher FCI gains than their male counterparts.The results presented here reflect the opposite and give rise to a discussion in terms of testingand the potential connection to gender issues. Research on standardized tests (i.e. SAT, GRE, LSAT, etc…) and their relationship togender have been widely reported in the literature [45 – 46]. In 1992, the American Associationof University Women Educational

This emphasis is reflected as the group creates a metric toevaluate their potential solutions.A specific case from undergraduate and graduate level engineering physics courses is describedto illustrate how the extensive work done in this arena in psychology, marketing, and businessenvironments can be applied to STEM education. Students were presented with the problem ofhow to measure the mass removed from a quarry. The classroom process is outlined and actualstudent results are presented to illustrate the method for other instructors who might be interestedin employing similar activities in a non-threatening, low-stakes learning environment.IntroductionIn the landmark report about
concepts inNewtonian mechanics.Acceleration is a concept of crucial importance, which is connected to velocity and force inkinematics and dynamics, respectively. However, this concept is rarely used directly in everydaylife, and there is a lack of vocabulary to describe it. In the specifications of automobiles,acceleration is not listed directly; instead, it is described in the acceleration time from 0 to 60mph. This example reflects the definition of acceleration, which connects the two relatedparameters: the change of velocity and the time interval. With the unit converted, students canfind the acceleration easily from the provided time interval.The concepts of centripetal acceleration and force are a little challenging for most students

the current and voltage probes, we estimate themeasurement error in the power and resistance to each be less than 1.5% over the entire range ofvalues plotted in Fig. 3. While the data was generated over the entire range of values of thecurrent, the plot has been truncated at a lower limit of 50mA of current. This ensures that thegraph reflects only the temperature range in which the radiative mechanism of power dissipationis dominant.

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

problem, students must write a detailed discussion comparing and contrasting theresults of the simulation with their manual analysis. This last step is critical for helping studentsadequately reflect on what the simulation is producing and whether or not the results are sensibleand in reasonable agreement with their manual analysis. Experience has shown that these kindsof exercises truly reinforce for students the distinction between simple device models used inmanual analysis and more detailed device models used in computer simulations. They alsoprepare students for professional practice by helping them gain basic proficiency with circuitsimulation software.IV.

the program has become much more attractive to potential majors.In addition, students who matriculated under the old program are able to choose whether tograduate under the old requirements or the new requirements. Of the students who had thischoice, six chose to graduate under the old standards, while twelve selected the new program,even though the requirements for graduation are more stringent under the new program. Themajority of students graduating since the change have opted for the traditional physics track,indicating that there is a strong desire for a solid grounding in physics and that the addition ofthis track served a need.The changes made tend to reflect the desires of students for a more rigorous traditional physicsprogram.

examples, most applications of theory are omitted. One reason that those examples arewell known is that they admit analytic solution: they typically represent simplified solutions thatgenerally fail to fully reflect the reality. In most situations, analytic solutions simply do not exist, andone cannot proceed without the assistance of a computer. Although some textbooks have sectionsdiscussing numerical methods, many of them contain just the theory of numerical methods, and one isrequired to posses programming skill for practice; this part is hence generally neglected. Essentially allexperiments in physics measure numbers, so any formulation must eventually be reducible to numbers.Under a conventional curriculum, a student’s ability to calculate

Numerous studies have pointed out the importance and value ofprompt and thoughtful feedback to students [27 – 31]. When students take time to reflect ontheir writing and on the instructor’s comments, the folder becomes a highly effective tool inhelping them uncover and then wrestle with their misconceptions while the learning is takingplace. The nature of the free-writing assignments varies depending on the goals and objectivesfor a particular topic or content area. For example, for some free-writing assignments studentsare asked to explain a problem or a concept that was highlighted or discussed during a

The cells in red in Tables 7, and 8 reflect the SLO’s where the percent average is less than 70%. A similar table is created for each course section, each time the course is taught. While these tables hold detailed information per student, the averaged data for the entire class is further used to create year-to-year comparisons such as the ones in Figures 1, and 2 below.

IntroductionThe use of Blackboard system [1] is widespread now and is recommended over regularcourse websites [2], as it is significantly more versatile for course management andinteraction with students. The system is most effective for distance courses [3] as onlinecourses [4] can be delivered in a consistent meaningful manner even if recent works showthat there are some challenges associated with distance learning [5]. The system has greatbuilt in flexibility and allows instructors to use their imagination in designing the course[6], interacting with students

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.
