accuracy in the order of 1 nanometer. Thus this method is suitable to inspect veryfine - close to mirror finish surfaces. Page 12.1107.3Light scattering technique uses a beam of light of known wave length that is projected onto asurface at an incident angle θ. Figure 3 shows the basic light scattering principle If the surface isperfectly smooth, the light will be reflected at the same angle as θ, according to the law ofreflection. However, if the surface is rough, the reflection will be scattered around the directionof specular reflection.. The diffused light intensity has close to linear relationship with surfaceroughness. The necessary link

methods for determining surface roughness have also beendeveloped. All of these methods operate under the principle that a reflection of a surface carriesinformation about that surface1. An example is shown in the figure. Figure 1 Reflected laserThere are many variations of using light to perform non-contact surface roughness measurement.One apparatus capable of accomplishing this has been developed by the EngineeringApplications Center at the University of Hartford. This design uses a solid state red laser toprovide a monochromatic collimated light source which is aimed perpendicularly to the surfacein question. The backscatter or diffuse reflection2 from the surface is reflected coaxially backtowards the

the powersupply for the isolated side of the circuit.Student reaction to Project GUISEThe 15 students who utilized Project GUISE in 2005 were asked for their reactions to it.An assessment instrument consisting of 12 statements was administered; students wereasked to state their level of agreement with the statements on a Likert scale where a ratingof 1 indicated strong disagreement and 5 indicated strong agreement. Table 1summarizes the results. The first seven statements in Table 1 are statements to whichagreement would indicate a favorable reaction to Project GUISE; agreement with theremaining five statements would indicate an unfavorable opinion. (The order of thestatements in Table 1 does not reflect their order in the questionnaire). On

learning to occur: 1) Active Experimentation (protoboards, simulations, case study,homework), 2) Reflective Observation (logs, journals, brainstorming), 3) AbstractConceptualization (lecture, papers, analogies), and 4) Concrete Experience (laboratories, fieldwork, observations). This project is investigating the impact on student learning outcomesproduced by incorporation of the Mobile Studio pedagogy in courses that will be delivered usingthe Kolb cycle to sequence the courses’ activities as follows: 1. Students are introduced to topics and are then asked to formulate hypotheses and plan/perform experiments to determine the validity of their intuition. 2. The students relate their outcomes to real-life applications and provide a sense as
