<p>QuantMech, yes, R.L. Moore is widely credited with the Inquiry-Based Learning (IBL) method and my S is darned happy he developed it. HCSSiM, a well-known summer math program, also uses this methodology, which is where S1 first came across it. S1 used it when he taught competition-level CS programming at his HS, with great success.</p>
<p>Chicago offers one section each year of IBL Analysis and S chose it over Chicago’s Honors Analysis (considered by some to be the equal or better of Harvard’s Math 55). They covered the same material as HA, but with the inquiry approach. He absolutely loved it. Chicago also offers a couple of sections of IBL Honors Calculus each year.</p>
<p>But I digress…</p>
