These initial findings openopportunities for future work on the role social network analysis can play in the analysis ofcollaborative learning.1. IntroductionReal world engineering design problems are frequently solved by teams; therefore, as educators,we are required, both by ABET and common sense, to give students the skills and attitudes thatenable them to work effectively in teams. One of the key skills is the ability to engage incollaborative learning with team members. In the process of acquiring the knowledge necessaryto solve the design problem, collaborative learning gives students the opportunity to both learnfrom and to teach their peers

In this paper, a threedimensional vertically articulated robot is created to help students visualize thelocation and orientation of the end effector. Students can check their robotkinematic answers based on the joint encoder values set up at each joint. Inaddition, a camera is also mounted on the robot for the students to relate an objectlocation from the camera coordinate system to the robot world frame.1.

strong science, technology, engineering, and math (STEM) workforce is essential and critical in advancing the economy and society of the future. But the U.S continues to trail the world in math and science. And also the number of U.S students pursuing a STEM career or educating is decreasing as mentioned in [1] – [3]. A change in the way math is taught and presented in the classroom is urgently needed. Instructors need to be able to engage the students in learning by communicating that the study of mathematics and its objective is not to study math for math sake but to be able to apply it as a tool to solve the world’s complex and essential problems. The topic of sustainable energy is no longer a topic reserved for scientists and

toacquire conceptual understanding of the topics taught. Consequently, a course’s assessmentshould at least in part evaluate this conceptual understanding. 1 To achieve this, there are multipleassessment methods that could be used, as for example essays or oral exams. However, many ofthese methods require a very high time investment on the part of the instructor, which is, in manycases, simply not possible. For large classes, multiple-choice tests are among the most efficienttypes of assessment. Although much care has to be taken in their development, machine-basedscoring of multiple-choice tests can significantly reduce an instructor’s work load, freeing uptime for more face to face interaction with students. However, one main point of criticism

Due to small class sizes, a more qualitative and in-depth approach was taken. Fromthis it was found that within the area of terminology, the concepts of power and energy causedsignificant issues for students. Furthermore, quantifying the impacts of technology from asustainability perspective, especially with respect to society and the environment, provedchallenging. With these specific areas identified, it will be up to future work to find mechanismsto address these pitfalls in subsequent offerings of this and other related courses.1.

Abstract For students learning a new topic, being able to use existing knowledge and mental models in the context of the new topic leads to faster learning and a deeper understanding of the new concepts. This paper describes how teaching a graduate-level course providing an introduction to optical engineering for students from multiple engineering majors can be facilitated by using existing concepts and knowledge of linear systems theory, which are common to them all.1 IntroductionThis paper presents an effective and efficient method of teaching a subject (optical engineering)which is new to students from various engineering disciplines. In particular, this method lever-ages existing student knowledge of linear
