We have foundMachine Design magazine’s website12 in particular to be an excellent source for this type ofarticle. For outcome i, we found a white paper on non-linear analysis from SolidWorksCorporation13 to be appropriate. After completing the non-linear analysis assignment, we gavethe students the assignment as follows: In this assignment, we used tabulated results that have been available for many decades along with non-linear software that was not readily available to engineering graduates of only a few years ago. Without a doubt, you will need to keep learning throughout your career. Besides formal classes, trade

EverydayExamples in Engineering make the new topics accessible to students and provide context as towhy they are learning the material and how it relates to their lives. Everyday examples are onlyeffective if they are relevant to the life experience to date of the college student. Engineeringinstructors with years of experience must reflect back to their level of experience and knowledgeas an undergraduate. For example, axial loading and deformation of composite members is anearly topic in the Mechanics of Materials course. A common textbook example for this topic,which many experienced engineers would consider an everyday example, is a concrete

How much time should students expect to the week's autograded work will take, and how will you make your question selection fit within that time budget? Despite its use of autograding, our course emphasizes

The three principal elements of the CoI model are social presence, cognitive presence andteaching presence. Social presence may be defined as the degree to which participants in thelearning environment feel affectively connected one to another; cognitive presence represents theextent to which learners are able to, via interactions with each other, construct and refine theirunderstanding of important ideas through reflection and discussion; and teaching presence is thedesign of various instructional activities such as lectures as well as activities intended to facilitateinteractions among students to help their

on a given course. From data gathered across all five courses, wefound that on average students spend 3-4 hours per week on online materials/videos, 1-2hours per week on online quizzes/assessments, and 3-4 hours per week on paper-basedproblem sets (if they are part of the course). (See Figure 1 below.)The total time spent outside of class time is therefore 7-10 hours per week. Given that thesecourses are 3-4 units apiece, this is consistent with the definition of a Carnegie unit, whichstates that 1 unit of academic credit reflects approximately 3 hours of work per week inside oroutside of class. To confirm this conclusion, we calculated the hourly range that each studentreported spending on the course overall, and defined that range as low

methodswhereby they achieve the learning objectives. This is deliberate as the instructor gives onlytechnical guidance and course lectures are for the most part generic and not specific to the widerange of projects that the students might choose. Therefore, successful completion of the courserequires students to design and undertake their own physical or computational experiments andthus take charge of their own learning.The following are some reflections on recent cohorts from the instructor’s point of view: • At the end of the semester, there is a high degree of enthusiasm exhibited by the students taking the course. Although some students complained in the surveys of the large workload, there are almost no drop-offs for

Overall, 92% of students rated the experience as“excellent” or “good”, but 8% of students did identify the mentoring experience as “lacking” or“poor”. The students were not provided with information on what a good mentoring relationshipmeans. Instead they were expected to reflect on their own expectations. In regards to thenegative experience one student commented: “My mentor seemed to push off all mentorship work to her PhD students.

Ifthe student received a “not mastered” mark, they would almost always redo the problem,regardless of overall performance level.Some exceptions to this occurred. First, students with poor attendance records and poor recordsof turning in the original assignment would also sometimes skip turning in resubmissions. This isnot viewed as a direct result of the mastery grading system, rather a reflection of general poorparticipation by a small percentage of students across any system. Second, some studentsindicated that if multiple resubmits piled up and important coursework from other classes alsobecame time consuming, they would

This attitudemay have resulted in behaviors (e.g., failure to complete assignments, ―giving up‖, etc.) thatultimately resulted in lower course grades, despite the concept inventory indication ofunderstanding.Course Evaluation ResultsCourse evaluation comments were used to evaluate the effectiveness of the methods used in thecourse.

Anecdotally,we hear from students that they do not like working on teams because they end up doing all ofthe team’s work; this is reflected in the pre-skit response of 30% of our students, who respondedthat they would simply take over the project. About 15% of the students before the skit said theywould talk to the teacher or stop working. After the skits, a full 15% more of the class said theywould call a team meeting if they noticed they were having trouble, equaling a 15% drop in thenumber of students who said they would take over the project.
