experiential learning was coupledwith discussions. This paper describes an instructional module to introduce the relationshipbetween the time domain and the frequency domain.BackgroundBalancing discussion with practice increases the effectiveness of technical courses whencompared to the traditional methods that rely on lectures and fixed lab experiences.1 Additionalbenefits can be gained by using the discussions to guide students to discover concepts throughthe practical experiences.2 In turn, these discoveries reinforce important results from thediscussions. An objective is to help the students to develop conceptual knowledge.3 In addition,careful topic sequencing helps student to view multiple representations of a concept in a coherentfashion.4The

The second digit describes the location of that maximum camber measured from the leading edge in percent of the chord. 3. The final two digits describe the maximum thickness of the airfoil in percent of the chord.With all percentages given in respect to the length of the chord, the classification of the NACA2412 determines that the airfoil has a maximum camber of 2% located at 40% from the leadingedge, with a maximum thickness of 12%.The professor desired to experiment with the learning process of the honors students.

suggest that even with today’s emphasis on first year programs in engineering themajority of engineering schools still depend on one or two credit, single semester, introductorycourses. The lack of prestige for professors associated with one credit introductory courses, aswell as the small effect on student GPA, leads to a situation where these courses becomeoutdated and irrelevant to the educational needs of the students13.At the Virginia Military Institute, the 1 credit hour Introduction to Mechanical Engineeringcourse, ME-105, had reached a point where it was of limited value to students, providing somebackground in manufacturing and design, but no information about the increasingly importantareas of programming and electromechanical systems

While the extruder had a classic PID(Proportional Integral Derivative) temperature controller, the spool motor did not work asintended. It seems that its motor driver would quickly overheat and stop applying power to thespool motor. So, the spool mechanism was bypassed. The extrusion machine was placed near theend of a table and the filament was allowed to simply drop on the floor. This worked, but itrequired some extra effort to wind filament onto the spool. Also, some experimentation with theextrusion machine was required to achieve the optimal extrusion
