Students spend one-quarter of the 150 hours of SL instruction (240 hours for HL; however, both numbers are merely recommendations and are not enforced) doing practical work in the laboratory. Group 4 subjects at the Standard Level are tailored for students who do not see themselves in further science instruction after leaving the programme. [7]
A workbook developed by Joshua Farley, Jon Erickson, and Herman Daly organizes the problem-solving process into (1) building the problem base, (2) analyzing the problem, (3) synthesizing the findings, and (4) communicating the results. Building the problem base includes choosing, defining, and structuring an ecological economic problem.
IB Film can be taken at either the standard level (SL) or higher level (HL).
