is also asked to verify FEA results withclosed-form calculations wherever possible. For example, plate theory4 shows the maximumnormal stress, S, around a hole can be calculated using: qRo 2 F7 S t2Where q = applied pressure, Ro = outer radius, t = plate thickness and F7 is a stress factor basedon the geometry of the plate. In addition to hand calculations, the student responsible for the structural analysis(student “A”), is asked to defend the accuracy of his or her FE analysis. Students are encouragedto report structural error and explore submodeling techniques on the crown plate. For example,Figure 5 shows submodeling on the crown plate a student performed to validate the accuracy ofhis FE model

another. One defining characteristic of an ODE is thatits derivatives are a function of one independent variable. The order of a differential equationis defined as the order of the highest derivative appearing in the equation and ODE can be ofany order. A general form of a first-order ODE can be written in the formdy/dx + p(x)y + q(x) + r = 0where p(x) and q(x) are functions of x. This equation can be rewritten as shown belowd/dx(y) +y p(x) = - q(x) - rwhere r is zero. A classical integrating factor method can be used for solving this lineardifferential equation of first order. The integrating factor is (exp)^∫p dx.Euler MethodGraphical methods produce plots of solutions to first order differential equations of the form y’ = f(x,y), where the

multiple reason for this, the first and foremost is that the quantile rank itself is a useful diagnostic tool that will allow the researcher to determine whether or not a logarithmic or other fit is useful for the student data. Depending on the nature of the research and the exam itself, one may choose to use the quantile as an indicator that a Q-Q plot should be used next. Quantile distribution functions themselves can take many forms, for example, the exponential quantile takes the form, log ! (1 − 𝑥) 𝑄 𝑥, 𝑦 = − 𝑦 Where, x is greater than 0 and less than 1.

A few examples are discussed here with specific strategies to promote studentlearning.Students often struggle to distinguish between isothermal and adiabatic processes. Students findit counter-intuitive that a system can absorb energy by a heat transfer, Q without a change intemperature during a process. In many cases the temperature increases with heating, but if thesystem undergoes a phase change at constant pressure the temperature remains constant.
