Figure 1: Rigid body dynamics questions given the first day of StaticsStudents’ answers were analyzed to see whether students understood that the body would bothtranslate and rotate in both cases, and coded accordingly. Performance on the rigid body motionquestions were correlated to student performance on the Conceptual Assessment Tool for Statics(CATS)* pre-test and post-test results, both overall and on the specific equilibrium questions, andon performance on the final exam, both overall and on two conceptual questions, one on
on areas that theywere weak in based on performance on previous problems. Our hope was that this would helpdirect students’ study habits and improve overall learning. Also, for this semester the number ofin class quizzes was further reduced, with 4 quizzes for statics and 2 for dynamics. Also thestatics exam was given over 2 class periods, as a common time for both sections of students wasnot available due to the students’ schedules.

Students are provided with several working assumptions, including (i) the use of higher strength “Group B” ASTM A-490 bolts (Figure 2b), with threads excluded from the shear plane, i.e. “X-condition” (Figure 2e), as per AISC 2011;9 (ii) specified plate width Wp = 52.5 in.; (iii) minimum anchor spacing of 3 in.; and (iv) specified edge distance of 1 ¼ in.

Students in our dynamics courses were asked to first watch two screen-captured example problems, each broken into several clips. Sample screenshots from one of thescreen-captured example problems are shown in Figure 1. (a) (b) Figure 1. Snapshots of two clips from the screencast for Example 4.6 used in the study.

challenge is a lower difficulty level problem dealing with the topic. Thestudent is provided with information needed to understand the challenge. In the engineeringdesign process, this is the stage of problem definition. The steps shown below represent theremainder of the cycle, which prepare the students to complete the challenge. a. Generate ideas: Students are asked to generate a list of issues and answers that they think are relevant to the challenge; to share ideas with fellow students, and to appreciate which ideas are new and to revise their list. In the engineering design process, the stage of generating ideas is the brainstorm stage. b. Multiple perspectives: The student is asked to elicit ideas

Upon review of the responses, it was revealed that the averagerating was a seven or eight for each of the concepts. A complete list of concepts included in thesurvey can be found in Appendix B. Some examples of these included representing a force usinga vector, the relationship between an arch's shape and the loads that it carries, and the mostefficient distribution for reinforcements along a silo. The fairly high average response shows thatstudents feel confident in their knowledge of the course topics.

That grading tookapproximately one week.Students in the experimental section had a much stricter exam grading rubric but could choose totake version B and/or version C of the exam (covering the same content but with new problems)according to the following rules. All of their exams were graded according to the mastery-gradedrubric set forth in [3] and summarized in Table 1. That grading took place the night of the examand grades were available for review immediately1 . This initial grading was strictly oncorrectness (for each problem, students received 0% or 100%) which allowed one professor plusone TA to grade over 100 students’ exams in less than two hours.

However, College Algebra is a prerequisite forPre-Calculus, which is a prerequisite for Calculus 1. Trigonometry is included in Pre-Calculus,whereas students may have taken Geometry in high school.

The authors highlight their experiences andpresent addition activities to improve student learning.Kaul and Sitaram20, present a combined course in Statics and Dynamics with many new featuresthat are not observed in the traditional courses. This course has added new learning outcomes toaccommodate laboratory experiences. The course has been designed for four credit hoursconsisting of 180 minutes of lecture time, 120 minutes of laboratory time and 60 minutes oftutoring time every week of the fourteen-week semester. The contact time has been distributed soas to promote scaffolding of the learning process. The learning outcomes established for thiscourse include ABET1 outcomes 'a' and 'e' as well as ABET1 outcomes 'b' and 'k'. Details of

method of incorporating animation into the student experience in the analysis of dynamics(especially vibrations) problems is presented. After a student models the problem, draws free-body diagrams, and derives equations of motion, he/she then obtains the solution for the positioncoordinates as functions of time. The student generates and plots the solution within a simpleMATLAB program in which all parameters, such as mass, stiffness, damping, lengths, initialconditions, etc. can be easily changed. The solution can be generated using either a closed formsolution or a numerical differential equation solver. In either case, at the end of the program, thestudent can animate his/her own solution by running an animation function file provided by
/blended (B), or passive/traditional lecture (L).Each student was assigned a random 4-digit personal code at the start of the term by one of theco-investigators. The Qualtrics surveys pushed identified attendance points to Canvas [30], butthe actual survey responses were stored by the 4-digit personal code without personal identifiers,and the personal codes were never disclosed to the instructor. Thus, the instructor was able toview survey results and respond to student concerns and motivations throughout the semesterwhile maintaining the anonymity of the students’ responses.Increasing students’ understanding of motivation and learning styles was one of the courseobjectives.

As one means of judging the level of correlations that might be expectedbetween the SCI and class-based performance measures, correlations between different classexams within a course were also calculated, and found to range from r = 0.32 to 0.73 [13].Summative Course PerformanceFor a summative measure of performance in class, we have used the mean of in-class examscores in the case of Miami and CMU, and the final grade (A, A-, B+,…) rendered into anumerical scale in the case of Itasca.Paper HomeworksWritten homework problems were assigned nearly

These courses are crucial in the engineering education process forthese disciplines because they introduce students to the engineering approach in problem solving,provide basic principles that are used in following courses, and let lower division studentsrecognize if they are equipped for an engineering curricula. In addition, many questions for theFundamentals of Engineering exam have their roots in these courses.Providing the proper teaching environment for these courses is a challenge for faculty anddepartment administrations because a) there are numerous students that must be accommodated,b) the students deserve a quality experience to
