A set of precisetechniques are based on a combination of inexpensive diode lasers, mirrors, and prisms. It is onadapting these techniques to laboratory experiments that this team will focus on.The following figures display the components of a preliminary design for creation and testing ofan apparatus for measurement of the angle of twist of bars by application of torque.

. The course is designed to provide students with instructional methods andcurricular materials appropriate for teaching science concepts, processes and skills in theelementary grades. The course reflects best practices for the teaching of science asoutlined in the National Science Education Standards and the Pennsylvania StateStandards. Each of these reform documents emphasizes an approach to the teaching andlearning of science, which highlights scientific inquiry as a prominent feature. As such,teaching science as inquiry serves as the foundation of the course.The major goals for the course include assisting students in developing positivedispositions toward science teaching and learning, becoming familiar with the goals ofcontemporary
degrees awarded to people in these underrepresented groups over thepast few decades, there is still much work to be done to diversify the profession to reflect thecountry‘s shifting demographics and to broaden perspectives used in developing newtechnologies and solving complex problems.The importance of diversity in the engineering workforce has been recognized as a priority by anumber of entities, including the National Academies. Engineers from diverse backgrounds andexperiences are needed to devise creative solutions to the challenges posed by a diverse andmore interconnected world.1 Recruitment of a diverse engineering workforce includes thesuccessful recruitment, retention and graduation of a diverse engineering student population.

. Recent revisions of theET program that include the addition of a four-year seminar series focusing on professionaldevelopment and documentation of student workplace competencies / program outcomes wentinto effect for students entering fall semester 2010. Students, as a requirement for graduation,must individually submit integrative and reflective ePortfolios to document with direct evidencetheir intellectual growth and mastery of the ET program’s workplace competencies. Compilationof the ePortfolio contributes to the students’ professional development, and its completion andsubmittal for summative evaluation in the senior seminar is considered a fundamental componentof the capstone experience. The four-year seminar series provides an opportunity
social systems become more complex, the aptitude for data-driven decisionmaking becomes even more critical. Data made publicly available through GRIDC provide atremendous educational tool for STEM students. Rather than simply reviewing journal papers orreports, they can analyze the data visually and build models to answer relevant questions.Analysis using recorded time series data gives students the opportunity to formulate sound, datadriven judgments based on technical visualizations about the performance of renewables. An advantage of using data derived from renewable energy technologies as a content areais that undergraduate students have the prerequisite knowledge to understand the technology andrelated data because the data reflect

Page 22.478.4In the last and the eighth lab “Transitions between confined subbands in the conduction andvalence bands in GaAs/AlGaAs heterostructure quantum wells (inter- and intra-bandtransitions)” students study properties of the objects with dimensionality higher than quantumdots – quantum wells (two-dimensional objects). In this experiment the students create a quasi-monochromatic light beam using the combination of a broadband source (tungsten-halogenlamp) and a grating spectrometer. The beam is reflected from the surface of a GaAs/AlGaAsquantum well and the intensity of the reflected light is measured as a function of the incidentphoton energy. The samples are placed in an exchange gas cryostat operating at liquid nitrogentemperature
consisting of five components: active learning, visual learning, challenge, applicability, and interest. Further, students rated the project courses significantly more positive on these dimensions. Finally, students were found to be near the mid-point on the ILS active/reflective and sequential/global dimensions; while strongly favoring a visual and sensing style on the visual/verbal and sensing/intuiting dimensions respectively.IntroductionElectric drive vehicles, or EDVs, represent a technology that has gained much attention over thepast decade. With the fluctuations in fuel prices as well as more visible pollution and recentdisasters, many industries and consumers alike are realizing the need for alternative
% error off of the measured value while the remaining groups average a 36% error. Asimilar trend is seen with those groups that include an atmospheric condition state in their model,with a 15% error in those that do and a 41% error with those that do not. This provides insight intothe successful methods of solving this MEA and what possible concepts the students are missing.Another method of assessing the MEA is a long reflection tool that allows the students to thinkabout what they learned and record the troubles and successes that they experienced. From thespring to the summer the students indicated in the reflection that they learned very similarconcepts; 63% of the students indicated that they learned about modeling a polytropic process
differing levels of experience with critical andanalytical thinking.BottlenecksIn the course of teaching engineering ethics a few possible bottlenecks exist. First, it could bedifficult to motivate students to take the course seriously as it is not one of the primaries in theengineering curriculum. Students will need to be convinced that the course is intended toencourage genuine moral reflection rather than mere recitation. This bottleneck could beovercome by creating an opportunity to exercise and refine students’ critical, moral abilities. Ifthey are invited to reflect on realistic, engaging case studies in ways that respect their moralcapabilities, they will sense that they are being respected as moral agents and thinkers in theirown right. As
these existing assessment tools is that they have been developed basedon different frameworks, and hence, the integration of non-consistent assessment tools into anoverall program assessment is challenging. Beard et al.7 suggest that an assessment plan toevaluate curricular efforts to integrate professional skills into programs should includestandardized rubrics.Beyond the studies that focused on assessment of individual skills (e.g., teamwork), a few recentstudies proposed more comprehensive assessment tools targeting a larger set of professionalskills. For example, Huyk et al.23 studied engineering students enrolled in multi-disciplinaryproject team courses to investigate the impact of reflections on the service learning and otherproject

In the semi-authentic professional communities of project teams with realstakeholders, social interactions will shape student learning 20, 23, 25.

professional practice, the culture of the classroom must emulate the community ofpractice [4-7]. The instructional approach that has guided the evolution of the course has beenbased on the following principles: • Business Environment. Assignments and assessments should be grounded in and resemble business practice. • Assignment Timing. Assessments and student reflection exercises should be coordinated with the completion of a major challenge. • Cycle Iteration. Multiple cycles of both the business model and technical solution generation are necessary. • External Reviews. External input and review of the projects is sought at every stage of the process.Each of these principles is discussed in paragraphs that
humanperceptions, understandings, and realities are based on the lived experiences of individuals(Cardellini, 2006; Crotty, 1998; Gordon, 2009; Kincheloe, 2005). Individuals create, interpret,and recognize knowledge in diverse and contextual ways (Windschitl, 2002). An individual isseen as an active knower and as a consequence personal reflections on experiences are integral tothe data collection process (Crotty, 1998; Fosnot, 2005; Schwandt, 2001). In the context of thethink aloud method discussed in this paper, students generated knowledge about their problem Page 22.1084.4solving strategies and approaches by reflecting actively and in real-time on

Preand Post surveys of each student’s view of their future role in science and engineering wereconducted to determine any change in perception or attitude. Further weekly emails sent by thestudents were collected to determine their growing awareness and confidence in theirunderstanding of each week’s reading and discussion. In response to the reading assignments onmedia and learning, a few students generated their own digital documentaries of student life. Thefindings from pre and post class surveys, along with the final anonymous student evaluations,indicated that most students found the class helped them

Also, participants were asked to rate 18 likert-scaled items on a scale of 5(1=strongly disagree, 5=strongly agree). The 18 items include: six that were designed to revealthe participants‟ interests in pursuing a PhD degree, three that were used to reflect the subjectivenorm, and nine that were used to reflect the participants‟ attitudes toward enrolling in PhDprograms. The 18 Likert-scaled items related to the interests, subjective norm, and attitudesrevealed a reliability of 0.91.

Thus, the beginning interviewquestions were about the details of the experience, and were followed by questions about theimpacts on themselves they have seen from these experiences. This interview protocol designallows students to remember deeply about the experience and therefore, reflect more deeplyabout the impact of the experience, how they changed because of the experience, and how theyview and approach interdisciplinary design in general. The interviews were audio recorded andlasted approximately one hour. An outline with example questions of the protocol is includedbelow.Focus of Questions Example

Thefour undecided majors were interspersed evenly within the groups completely of their own accord. Afterdividing into groups, and prior to receiving the assignment, the class introduced themselves and discussedwhy they chose their major. As a class, the students discussed what they thought a civil engineer was and did.In order to assess initial and final association and thereby engagement, students were asked to define what acivil engineer was and why they wanted to be a civil engineer in a reflective paper.

Specifically, we are tri- angulating across three assessment instruments, two of which we developed: (1) pre- and post- concept inventories to assess gain, (2) an online reflection tool to assess process, and (3) a grading rubric to assess the resultant artifact (general model and specific solution). We have also developed an instrument to measure students‟ self-efficacy scale related to their Page 22.314.3 modeling skills. Assessing the MEA motivated problem solving process: Through the use of various data col- lection tools

The instrument consists of 24-self-report items which require students to indicate thedegree of their problem solving skills across the following domains: problem identification,problem analysis and synthesis, and solution generation. The instrument also measured students’ability in conducting self-directed learning and reflection, which are very important elements indeveloping and enhancing problem solving skills. The instrument shows the degree of students’problem solving process skills, whether they usually take the surface or deep approach.

results in written and oral reports.The satellite communications project provides excellent applications of important concepts ofsignals: time shift, amplitude scaling, delay, echoes, and fading. We introduced students to asatellite communication system where a signal is transmitted from a ground transmitter, receivedby the satellite after some delay, and reflected back to the ground receiver. Students analyzed thesignal received by the ground station as the sum of the signal sent from the station and the signalreflected back from the satellite. This interesting project helped students to review sinusoidalsignals, phasors, power, and to understand the effect of delays, echoes and fading. In addition,the students simulated the system using

Through informal observations the authors realized students simplydid not have familiarity with the equipment at our facility (as opposed to their previousexperiences elsewhere). In this study, the authors target one simple skill relevant to resistancewelding that could be used as an introduction to metallurgy concepts (welding band saw blades).This student project was used not only to provide students with a practical skill for theirapplications toolbox but additionally as

Some of theproperties of this process include: frequent delivery via 2–4 week iterations; processimprovement via reflection workshops at the end of each iteration; osmotic communication byco-locating teams, and utilizing charts and boards to share information; personal safety; focusthrough a flexible plan that identifies fixed deliverables per iteration; and a technicalenvironment capable of supporting automated

Pervasive computingresearch has also been driven by examples like the communicators in Star Trek.10 (A colleaguehas declared for years that the point of engineering is to make life more like Star Trek.) Anexample of a similar course with a broader computing approach, including knowledge bases,web interaction and research, telepresence, virtual reality, and security as well as AI, is given bySanderson.11Course StructureThe structure of the course allows for students to grapple with ethical questions throughdiscussions, reflection papers and longer writing assignments. Technical content that lays thefoundation for an understanding of the state-of-the-art is presented through lectures similar tothose used in typical AI courses, but is tied
