On-center ganglion cells are excited when stimulated by light inthe center and inhibited when stimulated in the surround; off-center cells have the oppositeresponses”4. Up to this point all the cells involved in object and orientation recognition arelocated in the eye, while the next stage is the transmission of the stimulus to the brain.Simple and Complex Cells are found in the primary visual cortex located in the occipital lobe ofthe brain (refer to Figure 1).

Cool Stuff and we got heavilyinvolved with it from the beginning (reference 1). We could imagine the possibilities for theproduction of tooling and in the teaching of engineering design. We acquired our first systems in1993 and started to use them in the course. However, there were problems with ourinfrastructure for the course. We couldn’t yet support the rapid development of geometries in thetimeframe we had. We were constrained by the lack of a computer lab or adequate software.Also, we lost the existing foundry lab when we joined the Manufacturing department to

Under object oriented programming, everything is an object and all written code isrelated to class definitions and methods. While this approach offers flexibility and scalability, itrequires students to define class constructs before even basic programming concepts areunderstood – such as expressions, variables, conditional logic, loops, etc… This results in alearning curve that has increased rather than decrease.For example, the following is same Hello World example in the Java Programming Language.This code declares a

IntroductionFor a millennium, universities have been considered the main societal hub for knowledge andlearning. However, over the last several decades, the basic structures of how universities produceand disseminate knowledge and evaluate students have shifted in a new direction due to societalchanges created by technology—computers, internet, instant messaging, e-mail, Facebook, andtweeter. The transmission of knowledge need no longer be tethered to a college campus.

Both groups perceived that the flipped classroom approach promoted placing theresponsibility of learning on the students. We speculate that different levels of preparation forcollege were in part responsible for the mixed reception of the flipped classroom approach amongthe freshmen.1. Background:The flipped classroom approach inverts the traditional “teaching/lecture – learning/homework”model by presenting the course content outside of classroom ahead of the traditional lectureperiod and by replacing the lectures with active forms of learning in the classroom [1] [2].Typically, the content is delivered online

knowledge (for an overview, see Hoskinson et al.1). Problem solving,whereby one applies abstract principles in an expert-like fashion in order to achieve a goal, playsa central role in this endeavor.In physics, such abstract principles are commonly embodied through equations and instantiatedthrough word problems. Problems often refer to idealized objects or events (e.g., a block slidingon an inclined lane). Yet, rather than eliciting abstract thinking, such problems reinforce roteassociation with formulas and restrict transfer toward “real-life” situations. Many scholars deemidealized problems responsible for students developing a formulaic approach toward problemsolving (i.e., “plug and chug”), and ultimately leaving introductory courses with poor

Do we have the desire to regain our identity and serve our industry customer? 2. Who are we? Scientists or engineers? Graduate programs or undergraduate? What’s our first priority? 3.
