Machine Activity – modeling the actions of a 5-axis CNC machine onsimple component shapes with in-class reflection/ discussion,f) Material Selection Activity- using materials selection software to validate the choice ofmaterial and manufacturing process(es) for a selected component with a worksheet,g) Portable NDT (Non Destructive Testing) Kit – conducting an independent investigation within-class presentations and reflection/discussion, andh) Traditional Lecture. Page 14.1085.2Some of these activities are well-proven and the “Quick-n-Dirty” CNC machine activity, thematerial selection activity, the portable NDT kit will be highlighted in paper

students and "More Knowledgeable Others" (e.g.teachers, parents, coaches, peers, experts, etc.)4. The classroom must become more active andengaging. When the students in the course becomes more involved and the professor puts morethought into the course the desired outcome is quite likely. Dee Fink in his workshops across thecountry states that there are two methods engaged teachers can utilize to add meaning to theexperience. “One is by helping students learn about additional things, e.g., about themselves,about others, about learning.2 Students survey responses reflect that they prefer to see onlinecourse-management systems, like WebCT and Blackboard, operate faster and be moreinteractive, presenting things in video or audio formats. The course

embedded reinforced steel bars. The typical examplesare beams, footings, columns, roof slabs, and retaining walls. Wood, like stone has avery long history of use. Wood is cheaper, lighter and more easily shaped than any otherconstruction material. However, it is subject to decay and attack by certain insects and isalso flammable. The structure of wood is anisotropic and this is reflected in its physicaland mechanical properties which vary along and across the grains (Farag, 2008).The materials that are currently used in buildings are quite numerous and come in fivemajor families (Ashby et al, 2007):  Composites  Concrete, stone, ceramic, brick, glass, bitumen  Foams, fabrics and fibers  Metals, ferrous and non-ferrous  Polymers

motivations and interests. Csikszentmihalyi captures the personal andenvironmental aspects of creativity well in his statement that, “creativity does not happen insidepeople’s heads, but in the interaction between a person’s thoughts and a sociocultural context.”9Conceptualizations of AutonomyDeci and Ryan define autonomy as “volition – the organismic desire to self-organize experienceand behavior and to have activity be concordant with one’s integrated sense of self.”10 In hiswork in self-directed and lifelong learning, Candy describes autonomous individuals as thosewho are able to conceive of goals, exercise freedom of choice in thought and action, resistinward or outward constraints, self-reflect, fearlessly implement plans of action, exercise

select choices, which incorrectly reflect changesin the strength of bonds as the reason. The scientific explanation, however, is that the density ofdefects, technically known as dislocations are reduced during annealing. This is because a coldworked metal will recrystallize during annealing which sweeps out dislocations when newlyformed crystals are grown. Preliminary MCI data revealed that only 2% of students answeredcorrectly on questions in reference to this material. Team-based concept sketching activities areeffective in helping students learn these types of concepts13. Students showed only 11% gainwith lecture only, 56% gain in score to these questions teamwork discussions, and 73% afterengaging in teamwork discussions and concept
