"When students generate and test hypotheses, they are engaging in complex mental processes, applying content knowledge like facts and vocabulary, and enhancing their overall understanding of the content" (Pitler, Hubbell, Kuhn & Malenoski, 2007, p. 202). Generating and testing hypotheses is very much a constructionistic strategy. Constructivism/constructionism requires that students build their own meaning by building "something that they can share with others" (Laureate Education, Inc., 2009). Hypotheses are, by nature, meant to be shared and analyzed by others, leading to additional hypotheses. By posing a possible solution to a problem, students are retrieving information that is already known to them and synthesizing how this knowledge might fit with new observations.
"Technology can play a vital role in generating and testing hypotheses because new developments in probeware and interactive applets allow students to spend more time interpreting the data rather than gathering the data - a process that can be tedious and error prone" (Pitler, Hubbell, Kuhn & Malenoski, 2007, p. 203). Technology can be used to preform the multitude of calculations needed, accurately, allowing the student to focus on what the calculations and data show. Technology can also facilitate the exploration of possible alternative outcomes. By simply changing some of the data, students can explore the positive/negative changes that occur.
Instructional strategies like these and others correlate with the principles of constructivist/constructionist learning theories.
