If the lesson plans are written for beginning students, suggestions are included throughout the lesson plans for slight modifications that make the lesson more applicable for advanced students. If the lesson plans are written for advanced students, the reverse is true (suggestions are provided for teaching the unit with beginning students). Similarly, each lesson contains two levels of student handouts—beginning (labeled “B”) and advanced (labeled “A”). Teachers can choose which set best fit the capabilities of their students.c.

To build patch C, the surface edges of A and B were selectedand NURBS curves selected at edges 3 and 4. Selecting surface edges enables the surface tool tobase it’s continuity off a 3D surface, in this case patches A and B. To set the desired continuityfor patch C, the square surface edit box was opened. C’s edges 1 and 2 were set to curvature,edges 3 and 4 were set to free. This freedom enables the surface tool to position the patch C’ssurface cv’s and achieve surface curvature continuity at edges 1 and 2. The results are zebrastripes that

reasons for selecting a pump test and PTC 8.2 for this exercise. Perhaps themost obvious is that there is a pump available and it had been used in the course many timesbefore! Another is that space constraints in the laboratory usually require that the pump testingset-up be disassembled after use in a given Spring semester so that it must be (can be)reassembled by the students for “their” pump test. Besides these, there are also reasons thatderive from PTC 8.2 itself. Unlike many other PTCs, PTC 8.2 provides for two levels of testing;a “Type A” test and a “Type B” test. Type A testing is similar to most other PTC tests; it isintended to be run on large equipment (in this case, a boiler feed pump) in the as-installedcondition and it requires

classroom.Engineering faculty have found that using group work in their courses they achieve two mainobjectives: a) Students performance is better in comparison when students work individually;and b) students have the opportunity to face group work experience allowing them to learn howto work in group.However, faculty is often faced with problems when they assess group performance because it isdifficult to do assessments that reflect the actual performance of each member through the groupexperience without loosing the positive effect of working with groups. Usually assessment isreduced to an average of the group performance and to one evaluation at the end of the task.These types of assessments do not address and may even cause social loafing and/or inequity
