closed-form equations to solve textbook problems that are well-defined and thathave a unique answer, e.g. statics, dynamics and strength of materials. However, these samestudents are unsure how to apply these fundamental principles and closed-form equations thefirst time they are given the task of doing an engineering design of a system where theparameters are such that multiple solutions are possible. To give students a first exposure to areal-world product-development team-environment scenario, the design and analysis of linkagesis used as the central topic to integrate engineering analysis, design, CAD, project managementand technical writing into a semester-long design project. The students work in teams of fourand take a loosely defined
graphics class at a major university. The questionnaireindicates whether a person prefers one or multi-modal learning methods that include (V)visual,(A)aural, (R)read/write, and (K)kinesthetic. A demographic instrument was employed to gatherdata that assisted in classifying students as being at-risk of leaving college or not at-risk. Theresearchers used the Fisher exact test to analyze the collected data. The Fisher exact test is mostcommonly applied to evaluation of a hypothesis with data framed in a 2x2 contingency tablewhere chi-square assumptions are not individually met.1 The null hypotheses are evaluatedbased on the probability of determining a collection of “observed frequencies even moreextreme” than the set summarized in the contingency

to a studentcentric model, where students become part of the means of their own instruction. Active learningprovides a number of different strategies to accomplish this and these techniques have beenresearched and have been shown to be effective means of instruction2.Literature on active learning generally includes the following characteristics: • Students are involved in more than listening. • Less emphasis is placed on transmitting information and more on developing students’ skills. • Students are involved in higher-order thinking (analysis, synthesis, evaluation). • Students are engaged in activities (e.g. reading, discussing, writing). • Greater emphasis is placed on students’ exploration of their own attitudes and values3

In the next section, fourassignments are explained and discussed for each subject area.2. Design ProjectsThe class meets six hours a week for sixteen weeks. For each subject area four weeks areallotted, of those four weeks, two weeks are for lecture and two weeks are for project work. (Thesubjects and related assignments are summarized in Table 1.) Most of the project work consistsof problem analysis, generating 3D models and engineering drawings with Creo Parametric, andreport writing. For all modeling, drafting, and analysis purposes Creo software package is used.Class meets in a CAD lab with
that requires the creation of a revolved feature and a pattern, and having students write and sketch the modeling strategy they would choose to create the part. The strategies are collected, some of them are chosen for discussion, followed by a short Creo demo that walks step by step through creating the model of the sample figure. The model is already finished, but the features are shown and discussed one at a time as shown in Figure 2, steps A thru D, with each feature’s modeling strategy being the focus of the discussion, not how specifically to draw the profiles, locate the holes, and so on. All example problems are from the Bertoline [4] text. Figure 1 – Lecture
representative of the target phenomenon29. Eventhough social and cultural aspects of an investigation could play a part in understanding thephenomenon, the interest here is in students’ modeling as it relates to the cognitive core of thephenomenon30. The creation of models provide insight into the fundamental nature of thephenomenon and are powerful descriptive, predictive and explanatory tools, often underutilizedin science and problem-solving investigation31,32, 33,34,35. When models are conceptualized andcommunicated as part of mental schemas—knowledge, images and procedures in memory36—they can be leveraged as part of an iterative, transformative process necessary to refine studentmeaning-making. The process of imagining, expressing and negotiating

To explore how CADcompare can augmentinstructor grading to decrease grading times of 2D PDF CAD drawings, the grading times for eachsession will be compared to grading times taken in fall 2017, which did not include CADcompare(i.e., human-grader only).
