educational, integrate and apply the knowledgeobtained in courses such as statics, solid mechanics and instrumentation. It demonstrates thepotential use of strain gages as sensors. Strain gages, and signal conditioners are used tomeasure, calculate and analyze force by direct application of a concentrated or distributed loads.These experiments provide students with hands on experience with using strain gages, signalamplifiers, and conditioners and setting up and balancing Wheatstone bridge.IntroductionIn engineering education today, instrumentation and computer integration are increasinglybecoming part of teaching in classrooms. Faculty use new technologies to increase their teachingeffectiveness in their classrooms. In addition, laboratory
from other institutions taking 7 courses. Many of these courses haveterm projects. Quite often, students find they lack time to concentrate on their projects due toassignment deadlines, exams, and laboratory assignments. Time management thus becomes asignificant concern, as it affects the outcome of their design projects.The second factor relates to student perspectives on what is meant by “helpfulness.” It seems thatstudents found that traditional assignments and tutorials were more helpful to their learning. Onereason might be that traditional assignments and tutorials provide immediate feedback on howwell students understand the course materials, and students find this information to beimmediately helpful. Another reason might be that

between free-form and set-piece projects to maximizeexposure to core mechatronics concepts while minimizing peripheral tasks and, importantly,preserving a good measure of creativity. Students in the author's mechatronics class were givenpremade motorized XYZ platforms and challenged to "do something" with the machines for theirfinal projects. While the basic platform is prebuilt it is of such general nature as to permits awide range of original projects. The results of one semester of this new course design will bepresented and compared with the author's earlier experience teaching the same course but with arequired free-form final project.Introduction Mechatronics is most often taught with a substantial laboratory component to
topics including ceramic processing, Pb-free solder development, experimental design, and biomechanics.

difference one strategy is to use activities like computersimulations and hands-on experiments where students can actually see the differences betweenthe two types of loadings.A search in the engineering education literature on the mentioned subject did not provide anyresult. Few papers that discuss related courses like materials science look at other issues likemaking homework more interesting1. In the field of chemical engineering there are many papersthat discuss various aspects of laboratory experiments.

The actual graphs are plotted on the same graphs as the theoretical curves andthe students are to comment on the similarities and differences. Some university engineeringprograms have an adjacent heat transfer laboratory class to help students visualize the varioustopics, but some do not.Having the assignment be “mini” research papers instead of actual research papers lessens thework impact but at the same time increasing the students’ writing opportunities.

involved in the learning process taking place inthe classroom, as opposed to the teacher centric traditional lectures. Engineering faculty havelong been using such approaches in many of our courses, for example in courses which includeexperimental laboratories and projects. This initiative has prompted us to focus more consciouslyon the effect of teaching on, and the assessment of student learning. This paper will discuss avariety of design projects we are using throughout the curriculum in the Mechanical Engineeringprogram before the Senior Design Project, how they fit with the Learner Centered Instructioninitiative, as well as how they support the Program Outcomes and Program EducationalObjectives of our ABET accredited program.Projects from
motivation and learning can be achieved by making the students moreactive and in charge of their learning, which for example can be stimulated by involvement in“hands-on” activities like experiments and laboratory work 2. A project focusing on humanbody thermodynamics was developed as a complement to the traditional content of classicalengineering thermodynamics. The underlying idea was to exploit the general interest inhealth, food, fare and workout shared by many students, thus making the subject moreinteresting while at the same time extending the course to a wider arena. The project was usedin engineering thermodynamics courses for 4 different engineering programs at LinköpingUniversity, Sweden.During the project, the students worked in groups

Aseries of such challenge-questions were developed for the various chapters in the syllabus ofM&I.Several metrics were used to measure student learning including; homework, in-class-quizzes(both formative and summative), laboratory exercises, and midterm and final exams.

participation in laboratory or demonstration exercises in conjunction with a lecture produces a more positive learning outcome. (3) Although these demonstrations are useful, critical thinking skills are necessary to transform classroom knowledge into practical application. Students who are asked to explain what they experienced are better able to think critically. Unfortunately, if a student is not required to explain their experience, answers based on partial or incorrect understanding are more likely to occur. (3) In summary, students who are engaged with various forms of learning have a richer educational experience. A combination of lectures, discussions, interactive learning and demonstrations create a learning environment which

All of the students onthe design team had little or no experience in rapid prototyping or with RMU’s fused deposition3D modeler.

it wascompared to a traditional classroom course; at the end, it was determined that even though theonline course could be useful to help students understand fundamental concepts in Statics, itbecomes less effective than the face-to-face course when teaching students to solve a diversity ofpractical problems7. Kim et al.8 developed a hands-on mechanics laboratory, with online accessto some experimental setups. The laboratory was a co-requisite for ME students in the Staticscourse, but, it was optional for other majors. Such mechanics laboratory allowed students tounderstand Statics concepts better through instructor demonstrations and cooperative learninghands-on activities, group projects, and discussions; as a result, the failure and

the end of the semester, a general courseevaluation was given. This survey included the open ended question: Do you think that you learned engineering design in this course? If yes, HOW (through what classroom readings, activities, discussions, etc.?)Without prompting 35% of students mentioned the impromptu design projects. This may notseem like a huge percentage, but in a class where there are numerous ways to learn the designprocess (hands-on laboratories, homework, Beetlebot competition discussed above, impromptudesign, other in class projects, etc.), a 35% share of responses is actually quite significant. Thisshows that students were indeed interested in the projects, but also that they perceive them asbeing a good education
