Maintaining a persistent Twitter “back-channel” in a class canprovide the instructor with a metacognitive “narrative view” of the audience mind-set. The back-channel then allowsstudents to elaborate on course content, exchange ideas in real-time, and queue up questions for the instructor,particularly in large lectures where airtime for Q&A is limited.Advocating that students

specimens are cast in accordance with ASTM C31. These specimens are usedfor compressive strength tests at 1, 7, and 28 days. However, these specimens only require 68 pounds of material,leaving 148 pounds of concrete for waste. This waste, (37,740 pounds total) had been disposed of in an all-purposedumpster prior to the new zero-waste design.Other materials also became waste when fabricating these trial batches. In the mixing and testing of concrete, alltools and equipment are routinely rinsed after each batch to keep them in working condition and clean. On average,this rinsing requires 2 minutes: one minute for tools; and one minute for the mixer. At a metered flow rate (Q) of0.1426 gallons/second this represents 17.11 gallons of water per batch or

presentations provide anopportunity for all students to hear about the experiences of their peers and gain knowledge about the wide varietyand essentially cross-disciplinary nature of most engineering problems and opportunities. In addition the Mondaylectures afford an opportunity for talks plus ‘Q and A’ sessions with engineering alumni. There are also digitallyadministered “Super Tweets” and ‘virtual’ Group Research assignments. The course management system dividesstudents randomly into teams with five or six members, each of the resulting 56 groups were assigned differenttopics and were responsible for organizing themselves to produce a two page, single spaced, fully referenced,research report. The reports are posted to the web site for student
