For programming- or spreadsheet-focused lectures, we used Microsoft Excel,VBA within Excel, MATLAB, or Simulink as appropriate, and could readily switch the videocapture between the programming environment and the relevant PowerPoints as needed. Ourpractice of splitting the lectures led to typical segment lengths of 5 – 15 minutes, and total videocontent per class period of 30 – 40 minutes.From a delivery standpoint, we initially used a flipped model in the Y3NM class.

Funding for a high percentage of construction projects come frommultilateral development agencies (MDA) like the World Bank or Asian DevelopmentBank.
