Engage Students in Investigation Tasks That Require Them to Generate and Test Hypotheses Investigation is the process of testing hypotheses past, present, or future events. Marzano (1992) refers to three types of investigation: historical, definitional, and projective investigation. Historical investigation involves answering questions such as, What really happened?, and Why did X happen? For example, students are engaged in historical investigation when they examine historical questions such as the following: Why did Homo sapiens survive and flourish when Neanderthals died out? How were the pyramids of Egypt built with the limited technology of the day? Projective investigation involves answering questions such as, would happen if ?” For example, “What students are engaged in projective investigation when they examine questions such as the following:
