Dr. Jeffrey Sachs was a pretty good professor. He wrote the Book on ending poverty, and the charm of his 8:30AM class was well-compensated for by his smooth slides and practiced presentations, taken directly from his myriad speeches around the world on the topic. And the slides were quite repetitive. (Though the Professor never once managed to finish all the slides he prepared for each class)The Professor took a whole semester to cover what could have been covered in three or four weeks. Nevertheless, it was a very enjoyable experience, and a solid first run-through - he called our class his "maiden voyage" - I learned a lot. If anything, this class helped me figure out what other classes to take (and not take) if I want to pursue humanitarian work in development. The class sprawled all over the field of SusDev, lightly touching on multiple disciplines: demonstrating the Solow Model of Macroeconomics, the Hadley Cells of Climate Systems, the Millenium Development Goals of the UN, a dozen two-to-three-letter codes for all the Earth's climate zones, spreadsheets, country case studies, a couple of slides for each environmental hazard, some essays to write at home and on the final, a few words on governance and corruption (or rather geography), a few words on economic incentives, and before you knew it the class was over. I definitely came out of the class feeling like I didn't learn very much about anything in depth. But seeing as it's an introductory-level class, it definitely serves its purpose of attracting students to the field: Sustainable Development IS Sexy, and it's Sachs who made it so.
