Session 2230 Learning Essays and the Reflective Learner: Supporting Reflection in Engineering Design Education Jennifer Turns, Wendy Newstetter, Janet K. Allen, and Farrokh Mistree Georgia Institute of TechnologyAbstract: Learning engineering design requires more than simply having design experiences.Design experiences provide a context for students to practice design skills and an opportunity forstudents to learn deep lessons about the nature of engineering design. Reflection on theexperiences is necessary in order to recognize and realize these lessons. Student questions like“Why do we

Gender Differences in the Learning Preferences of Engineering Students P.A. Rosati The University of Western Ontario AbstractThe results are compared of the responses of female and male engineering students to anIndex of Learning Styles. This self-report forced-choice instrument classifies the learningpreferences of the respondents on four scales; Active/Reflective, Sensing/Intuition,Visual/Verbal and Sequential/Global. Both male and female students showed a clearpreference for Active, Sensing, Visual, Sequential learning. However, the female students’learning preferences were

The writingincluded in a portfolio may be selected by the student or assigned by the teacher; it may cover anentire college career or a single semester; it may include samples from only one class or from anentire curriculum; it may include peer or student commentary or evaluation, or it may simplyinclude the student’s work. Any of these approaches may be successful if the instructor has aclear purpose for asking students to maintain portfolios and if this purpose is clearly articulatedto students. In the best cases, portfolios help students reflect on their growth as writers, helpstudents to interact with peers in the discussion of writing, and help faculty and students todiscuss ways in which students may become better writers.

There is no shortage ofmodels in the literature from which to choose; Bloom, Dewey, Perry, and others have allproposed various models to describe the process of learning.4-7 Given our emphasis ondeveloping our students’ ability to frame and resolve ill-defined problems, the authors find themost suitable model for our efforts in this context to be the reflective judgment model of adultcognitive development.8-12 The skills required to frame and resolve ill-defined problems areimbedded in the reflective judgment model, which has been validated by over 20 years of cross-sectional and

Such a sensor, called a reflective sensor, produced values in the range from 0 to 255inclusive and is regarded as an “analog” sensor (in contrast to the “digital” sensor that producesonly two values, 0 and 1). The students were encouraged to experiment with the reflective Page 2.445.3sensors applied to various surfaces to see what range of values would typically be produced whenlight was reflected from a nearby surface.The students discovered that reflective sensors could be used to determine

Within this context: • There is a gradual reduction in the amount of direction offered in the lab handouts,coupled with an increased frequency of answering a question with an experimental question. • There is an active encouragement for creative experimentation (and fun) through a moreleisurely and reflective pace of experimental activity. The relaxed pace of the laboratory allowsfor peer group teaching and learning. Students are free to look at a variety of experimentalsolutions, generated by their peers, and incorporate a variety of ideas in their own approach.Prior to computerization, however, alternative experimental approaches often remainedunexplored because: • Data acquisition was often tedious; so

] has proposed anew paradigm of scholarship, one that not only promotes the scholarship of discoveringknowledge, but also celebrates the scholarship of integrating knowledge, of communicating Page 2.243.1knowledge, and of applying knowledge through service. Service, in this context, means far morethan simply doing good, although that is important. Rather it means that students and professorsapply knowledge to real-life problems, use the experience to revise their theories, and become“reflective practitioners.” Service may be defined as a credit-bearing experience in which thestudents are involved in community service and reflect on the

The apparatus consists of a transparentplastic tube fitted at one end with a twin loudspeaker enclosure, and at the other with a heavysample holder on which the sample material is mounted. A small microphone may be movedaxially along the length of the tube and its position measured.The loud speakers are fed with a variable common pure tone (single frequency) from a functiongenerator and the sound waves produced pass along the tube sample.

The reality is rather dramaticallydifferent, in that the U.S. presently produces over 20% of its electricity from nuclear power, andmany countries around the world generate a much higher fraction. There has been no newnuclear plant ordered in the US during the past fifteen years, but by contrast the world demandfor nuclear electric power is accelerating.Utility production of nuclear electricity in the U.S. is under competitive pressure fromalternative technologies, including coal and natural gas.

sense in which all profession practice is designlike, must be learned by doing. However much students may learn about designing from lectures or readings, there is a substantial component of design competence--indeed, the heart of it--that they cannot learn in this way. A designlike practice is learnable but is not teachable by classroom methods. And when students are helped to learn design, the interventions most useful to them are more like coaching than teaching--as in a reflective practicum.Learning to think like an engineer means learning to do both analysis and synthesis both aloneand with a group of team members. Learning that is informal, social, and focused on meaningfulproblems helps create

1 System OverviewThis implementation of LabVIEW illustrates the fundamental radar principles at acousticalfrequencies. An ultrasonic transducer is the heart of the system. It acts first as a transmitter andlater as a receiver. In the transmit mode, the ultrasonic transducer transmits 16 sonic pulses at49.4 kHz. These pulses propagate through space with the speed of sound toward the nearestobject and are reflected by it. The reflected pulses, or echoes, travel back toward the ultrasonictransducer which now switches to the receive mode. The time difference between the transmittedpulse and the echo can be converted into distance to the object by appropriate scaling.In this implementation, LabVIEW is used to

This new vocabulary arises at least in part fromcultural changes related to technology, changes that we need to understand and exploit in order toeffect significant change in a curriculum that has proved remarkably resistant to change.

Thefaculty are divided into two groups and are asked to rank issues related to the curriculum renewalprocess.

Engineers?MIT's first Dean for Undergraduate Education, the late Margaret MacVicar, once noted [1] thatthe challenge for educators with respect to integration of engineering, humanities and socialsciences is to bring about: “...a true educational partnership among the technical, arts, social andhumanistic disciplines so that on some level students see the interrelationships between scienceand technology on the one hand, and societal, political, and ethical forces on the other.”One approach to exploring such interrelationships is through the STS courses and programs thathave sprung up over the past quarter century.

exchangeTIME-ON-TASKHow do you help students spend time productively on the learning task? Some guides to keepingstudents on the target and on the task:At the beginning of the task • Rationalize the task and tell students. • Have clear, unambiguous, observable goals. • Tell the goals to the students. • Explain the route ahead. • Use transparencies or written material to enrich instructions. • Ask :Everyone clear on the task?" before starting. • Identify the allowed time (use "30 seconds" instead of "1/2 minute").During the task • Monitor the time, ask "Everyone completed?" or "20 seconds more?" • Use and display a timer, or use a bell not a buzzer.After the task is completed • Always close with reflection, "What have you
