input signal is displayed onthe computer screen along with the error signal or the measured position output from the shaftencoder. The resolution of the measured value is limited to the number of tracks on the encoderdisc. The encoder has six tracks, so the resolution is 2*6 = 64 levels. This results in the measuredvalue having a more stepped appearance. The diagram of Figure 2 shows how the system blocksare connected for this experiment. Figure 2.

diversity ofperspective and experience. To help all students develop the skills necessary to attract, retain,and consider the needs of diverse populations, engineering students need to consider socialresponsibility in the context of their engineering careers and scope of practice [6].To help promote engineering students’ ability to develop their social responsibility capacity, theUniversity of Massachusetts Lowell S-STEM program began with an initial plan to recruit threecohorts of 8 low-income, high-achieving students (24 students total) who wish to pursue a careerin higher education (e.g., faculty at community colleges or universities) and engage them inongoing social responsibility and identity formation curriculum.

Extensive pre and post surveys were administered to the students toevaluate the course‟s effectiveness in using building performance simulation to teachhigh performance and integrated design. Insight was gained on how to introducecomprehensive simulation tools into the design studio, how to integrate mechanicalengineering students more effectively into architectural courses, and how architects andengineers can work together around an energy model.2. IntroductionIn contemporary practice, two factors have a substantial impact on the way that wedesign buildings. The first, integrated design, is an old concept that has seen newpopularity in light of the need for deep energy savings in new and existing buildings. The second

In self- paced Personalized System of Instruction (PSI) courses, observationalopportunities can be further limited.Yet PSI can be an effective teaching strategy for course material such as that in a first-year, web-based, introductory programming course. Students (particularly first-year students) have diversebackgrounds and a varied technical literacy. In this particular course, students complete 18 unitsfollowing a traditional PSI s-curve (reviewed below) in terms of content difficulty over thecourse of one semester. The content introduces students to two syntaxes and three programmingparadigms (compiled, interpreted, and object-oriented languages). The PSI format allowsindividuals to invest
