Approximation of stretch cord path on top of canoe.Briefly stated, the solution proceeds as follows. From the given deformed geometry the length ofstretched cord can be found and average normal strain determined. Using Hooke’s law the aver-age normal stress can be found. Knowing the diameter of the cord the area of cross-section can befound and the internal tension in the cord can be determined. By equilibrium the

a problem.To address the first hypothesis, the self-assessment responses for each course objective of eachstudent were averaged together and compared to his/her course grade. To place the course gradein numeric format the center of the MSOE grading scale for each letter grade was used (A=96.5,AB=90.5, B=85.5, BC=82.5, C=78.5,CD=75, D=71.5, F=50). (Of these only the choice of F wasrather arbitrary.) The data was then sorted on a course-by-course basis based on each student’scourse grade. The ratio of self-assessment average to course grade was then taken and normalizedto a scale of 1 (with a 1 meaning a student perfectly self-assessed, below 1 was an under-assessment of their ability, and above 1 was on over-assessment of their ability

set theory like set notations, set operations, definition offunctions is not taught well enough neither at high school nor at freshman math classes at manyuniversities. Students usually understand the notations like A Υ B or A Ι ( B Υ C ) , but thenotation f : A → B has to be explained. Also image and preimage of a subset seems to be newnotations for a majority of students. Cardinality of a set should be introduced (at least for finite Xsets) prior to introduction of the power set 2 to explain this notation. Indeed the notation Xbecomes natural from the equality | 2 | = 2| X | .Since engineering students tend to dislike the theory, they need to be

With fewexceptions, most secondary school programs fail to address the issues motivating this project,namely: a) providing students with a broad understanding of software development early in theireducation; b) dispelling myths about software development careers; and c) motivating students(especially females and minorities) to further study in this field.

In this paper we limit our focus to a single aspect ofconstraint theory; specifically, we consider in the next section the pictorial representation ofmathematical relations in the form of constraint graphs.2.2 Anatomy of a Constraint and its GraphConstraints have been called functions, requirements, relations, and rules in the literature. Despitethe abundance of terms, a constraint is simply an explicit relationship among variables typicallystated in the form of a mathematical expression. For example, the constraint represented by theequation a = b × c relates the variables {a, b, c} utilizing the operators {= , ×}, thereby specifyinghow allowable values are

This projectsimulates a common scenario in engineering field: when design changes, the sequence of theoperations will change correspondingly. In this case study, students are first asked to work ingroup to produce a trial part, which has simpler geometry (Figure 3 (a) and (b)). To help studentsfind the solution to produce the part, instructors pose some questions as hint and guidance.
