Ability to function well on teams 2. Ability to communicate effectively 3. Understanding of different, often conflicting perspectives and the need to carefully balance trade-offs when making decisions 4. Understanding of professional, ethical and social responsibilitiesThe reflective exercises employed began with a pre-course reflection essay and continuedthrough the 10 week term with periodic reflective journaling assignments.

ofcompetence with both 2-D and 3-D CADD programs, as well as an introduction to somefunctions that are commonly used in industry, such as assembly modeling and sheet metaldesign. To meet these new goals, the course is being reconfigured such that 2/3 instead of 1/3 ofclass time is spent on CADD. This reconfiguration has been implemented on a pilot basis in oneof three sections of the course.In the process of redesigning the course, pre-existing goals must not be thoughtlessly ignored.Therefore, a reconfiguration method was developed that maps the connection between lessonplans and course objectives from the original to the new structure. It is anticipated that thismethod will be useful in the future, as ET0011 continues to adapt to the continually

Briefly, the goals of the building are that it be: 1. a Positive energy building, using renewable sources to create more than enough energy to fund itself and neighboring buildings; 2. Net-zero for storm water output; and 3. a Living example of sustainable construction. The building itself will educate. All energy systems, mechanical, electrical, and renewable, will be transparent.

. Communication tools were identified as a necessary component to improvestudent usage and also to create a sense of community within the LMS. Training for both instructors andstudents was also a constant theme in the discussions. Since students communicated that they were notgiven formal training in the LMS, their engagement within the system was delayed.Finally, two major findings in the study were that the LMS must (1) contain the necessary tools thatstudents require to support their courses and (2) that instructors must set up the LMS effectively toencourage both engagement and a “sense of community” for students. Students count on being able tohave all of the necessary elements within their reach in a LMS to aid them with their

It can also be used in noiserejection. The PLL is thus a valuable circuit in any application where precise control of afrequency signal is required.Both analog and digital PLLs exist, depending on the application. The PLL has three basiccomponents, as seen in Figure 1. Figure 1.

. Moodle is used worldwide, and currently there are 46,388 currently active sites thathave registered for Moodle from 206 countries.One of the main advantages of Moodle is its structure, which can either be a topic based or time(weekly) based, as opposed to a module based structure. There is a section before week 1 wheregeneral links, that are not dependent on a specific weekly assignment, can be placed.The weekly structure allows an instructor to mirror his or her own syllabus for the course. Thus,each week is outlined in the Moodle page, along with links to information, uploads and grades.The time to develop the first Moodle page varies, but if you have a detailed syllabus, it shouldtake approximately 2-3 hours to first populate the Moodle page
