Drafting andDesign) software in the market worldwide. In fact it is the software commonly used inintroducing CAD (Computer-Aided Drafting) to students at High Schools, Junior Colleges and inmany Universities. AutoCAD is unquestionably the most popular software for 2D designdrafting but is not so commonly used in solid modeling. However, with good mastering,AutoCAD solid modeling is highly versatile and can be competitive in small and mid-sizedengineering design and consulting firms who lack financial resources for investment in rapidlychanging parametric solid modelers.This paper explores the teaching of solid modeling using AutoCAD. It presents a two phaseprocedural technique (planning and construction) that helps students to master solid

plans for the future. A discussion on theconcept of a polytechnic institution, its definition, and transformative nature is included to clarifythe reasons behind this radical and somewhat unsettling approach to education reformation.IntroductionAcademic institutions of higher learning are facing many difficult challenges, includingdeclining enrollment trends, complaints about costs vs. value, curricular stagnation, and inabilityto adapt quickly to changing environments facing graduating students. Many researchers andauthors claim that the traditional educational methods and structure espoused by universities isoutdated and potentially restrictive to learners. 1, 2 The College of Technology at PurdueUniversity is dealing with these challenges

Some educators instruct primarilyusing methods that they experienced as students. They use instructional strategies that havesuccessfully produced results over time. Others are reflective practitioners and ponder the theorythat motivates their classroom instruction. The learning theory they embrace informs the types ofinstructional strategies they use in the

Indeed, the resolution of a Performance Indicator may even be atthe level of specific exam questions, etc. A “weighted average” summary for each courseoutcome may be automatically generated. As discussed in the next section, this weightedaverage data may be utilized to aid in program-level assessment. Finally, this table may then bemanually augmented with the instructor’s comments on potential future plans to improveobtainment of any given course outcome. In summary, ACAT’s course-level

peer assessment plan, students handed a print of the multiview drawing in tothe instructor at the beginning of lab then the assignments were redistributed to the students sothey could assess the drawings and mark any errors. Correctly identifying the majority of theerrors on the drawing they marked up was part of each student’s grade. Actual grading andassigning point values to the errors was not part of the peer review, this was done by theinstructor.Grades on the individual assignments along with final project and exam scores were compared tothose from previous semesters. Grades on the individual assignments improved significantly butthere were no significant differences in the exam grades or overall grades. This may be due, inpart, to the

weekafter the submission). Although the students were allowed to meet the instructor and discuss theirmistakes during the office hours, they never received additional grades for such an extra effort.Though detailed records of these meetings were not kept, it was estimated that approximately40% of the students met the instructor more than two times for additional help outside theclassroom. In order to aid in the development of their spatial visualization skills, the feedback ontheir homework assignments were very detailed and the instructor provided them explanations ofthe areas where they needed to improve. In order to avoid any ethical conflicts, a pre-planned grading plan was formulated for thetwo classes. In the control class, the grading

This requires students to create the component in the FeatureCAM programas well as the associated process plan. The process plan requires the student to identify whichtools are necessary to machine the component. Two examples are shown in Figures 4 and 5.Overall lab grades for the CAM Course are reported as out of 100 possible points. a. b. Figure 5.

More important in some industries than others - such as civil, floor plan layout. • While I am appalled that many studying engineering can't fathom the distance between a mile and a micron, the F for fit to screen key has reduced the need to teach scale in introductory courses

environment. The Spatial Visualization Trainer (SVT) App was developed initially forthe iPad tablet with plans to expand to other platforms in the future. The App allows students toperform sketching exercises on a touchscreen. When a sketch is completed, a grading algorithmautomatically grades the sketch and provides immediate feedback. The goal is to create a moreengaging and more cost-effective spatial visualization training method.The SVT App could ultimately be used in the classroom, independent learning, or a hybridenvironment. While independent learning may provide the students with the maximum amountof flexibility and the lowest instructional costs, recent attempts with on-line learning havereported a low level of student engagement resulting
