This document discusses teaching biology at the Institute of Biology at the University of the Philippines, Diliman. It covers several topics: 1. The challenges of teaching the broad topic of biology and helping students retain key concepts rather than just facts. 2. Examples of how biological concepts like bioinformatics and biogeography are taught, including using databases, molecular phylogeny, and geographic patterns of species distribution. 3. Different student reactions to concepts like evolution and how the teacher addresses these concepts by laying out facts and asking students to critically analyze the evidence.
