through a big transition of the programwith one professor retirement (founder of the program) and two new faculty members arriving.Our recent activities comprise following three major parts: 1) Expanded teaching laboratory, 2)Strong faculty/students research projects, and 3) Active SPIE student club. We are presenting theabove three efforts in this paper.1. IntroductionCalifornia Polytechnic State University (Cal Poly) has one of the nation's largest primarilyundergraduate engineering colleges. The photonics program within the EE department began in1985. Currently, there are two senior elective lecture courses and one graduate-level lecture inthe photonics area. A 700 ft2 fiber-optics laboratory was introduced in 1986. This laboratoryserves dual

our program with approximately 30% of our graduates entering topten chemical engineering graduate programs, 100% student placement of graduates almost everyyear, and a host of university-based, state, and national awards going to our students.IntroductionMost faculty appointments in the United States carry the expectation that there will be a balanceamong different work activities[1-4]. The typical assumed split on a time percentage basis is40% on research, 40% on teaching, and 20% on service, although those percentages vary inreality[5]. One way of meeting service obligations is for faculty to take on the task of advisingstudents in their disciplines[4, 6, 7].

Load Theory (CLT) provides guidelines to present information in a mannerthat encourages learning and optimizes intellectual performance [1]. As an example, considerthe obstacles in learning new material in a non-native language. Clearly, there is an overload:learners must master the new material and the language itself. Interestingly, this is resonant withthe challenge of learning to program a computer (learners must master operating systems and thesyntax) for students not in the computer science major. CLT can mitigate challenges in suchcases when learning loads are high. CLT was used to re-design a computer programming classfor mechanical engineers at San Diego State University. According to CLT, information can only be stored in long

Concept mapping exercises and scores contributed to six percentof the students' final grades. During the four weeks, students participated in a 50 minute longintroductory workshop on concept maps on other topics. Students were then given a case studywhere they worked in a team for 1 week to make a concept map detailing the interrelationshipsbetween different concepts and the case study. The 1 week time period included a 2 hourworkshop where students discussed their work with the faculty members.

Theory of reflectance optical detection systemThe physical requirement necessary for an optical system in order to detect multiple numbers ofchromopores is to have light sources of specific wavelength with different absoptivity pattern.The light attenuation between the source and the detector can be written as follows: ⎛I ⎞ − log10 ⎜ out ⎟ = ODλ ⎜I ⎟ (1) ⎝ in ⎠where I in is the incident light, I out is the detected light, and ODλ is the optical density forwavelength λ .

redevelopment effortwas made possible by the support of the Cal Poly CTL.Backward DesignVery few of us, as engineering educators, have had a formal course in pedagogy. Therefore, inaddition to the challenging task of developing new and improving existing courses, we also haveto battle with our lack of formal training in the area of course design. However, there is a richfield of instructional design literature from which we can draw.Backward course design is one method that can guide instructors as they struggle with designingtheir own courses or even an individual lecture (McTighe & Wiggins, 2005). The steps inbackward course design include: (1) identify the desired results, (2) determine the acceptableevidence, and (3) plan learning experiences

prerequisite for courses such as controls, mechatronics, modeling of dynamic systems, vibrations, and capstone design. Course Structure Beginning in fall 2000 the 16-week semester course was restructured such that 8 weeks are devoted to the theory of numerical analysis and problem solving in the MATLAB environment. The numerical techniques covered in this course spanned topics encountered in a typical numerical methods textbook(1-3). The topics covered are: introduction to linear algebra, the solution of systems of linear equations, curve-fitting, interpolation, and the solution of ordinary differential equations. In the next 2 weeks a brief introduction to controls and/or vibrations is given. The accompanying laboratory exercises involve

The potentiometer is fixed on a plastic stand at the proper height, so thatthe pendulum can swing freely. A 2” propeller U-80 is attached to the motor shaft to produce athrust force in order to control the angular displacement of the pendulum from the verticalposition (fig. 1). A custom designed circuit board produces the controlled voltage supply for themotor via Pulse-Width Modulation (PWM) with a resolution of 0.05V, and reads out the voltageon the potentiometer, which is proportional to the angular position of the pendulum.

Four content areas were also defined. Theseare: (1) technology and society, (2) design, (3) products and systems, and (4) characteristics,concepts, and connections.

Rather than pushing students toward a particular solution, MEAs focus on thedevelopment of an adaptive problem solving strategy or model that can be repeatedly used. Theoriginators of MEAs propose six primary principles to develop new problems [1]. 1) The Model-Construction Principle requires that the students come up with a procedure for explaining a “mathematically significant” situation. 2) The Reality Principle puts the problem in context and offers a client who needs a realistic engineering solution to a problem. 3) The Self-Assessment Principle enables students to

This type of knowledge plays a very important role incompleting tasks which require hands-on experience, or in solving problems which may ariseoften or need to be completed quickly without time for thought or analysis [1]. Proceduralknowledge, however, has limitations and does not necessarily correspond to a strong conceptualunderstanding of the concepts at hand. It is typically applicable to one

Currently, the students can check their analysisby seeing if their calculated launch distance corresponded with the actual distance on launch day.However, this self-assessment will be expanded by the instrumentation of strain gages and anaccelerometer - allowing for the verification of predicted results with experimental data.   Figure 1.

Consequently, engineering education has the objective of not only presenting thescientific principles, i.e., engineering science, but also of teaching students how to apply these toreal problems. It is not surprising, therefore, that hands-on laboratories have been an integral part ofthe engineering curriculum since its inception [1]. Their importance has been recognized by theAccreditation Board of Engineering Education (ABET) and its predecessors by creation of criteriarequiring adequate laboratory practice for students [2-6].
