Our book, "Using technology with classroom instruction that Works" discussed different ways to generate and test hypotheses. One teacher, Mrs. Omar, focused on her students learning "that compounding interest and saving money can lead to strong earnings over time" (2007, McRel). She gave each group 3 plans for what they would do with a $10,000 inheritance. Throughout her lesson she had the students working in groups and testing each scenario by entering in numbers, and seeing which plan would work best, and how each investment would end up. The students were first asked to think of a hypothesis before they tested each plan, and then discovered the results over a 30 year period.
I believe this lesson demonstrates a combination of both a constructivist theory and a constructionist theory. The reason I think it demonstrates some of a constructivist theory is that the students are constructing their own beliefs and meanings from this assignment. In addition, their teacher created the spreadsheet, and then just had the students enter in their data. However, I think it is also partially a constructionist theory, because the students created a hypothesis, and then built their knowledge from trial and error. They discovered what would work best for their investment, and learned from applying educational technology. I think the students were engaged during the whole assignment, and this experience was more beneficial than reading about compound interest and saving money. The teacher did state that she created the spreadsheet for the students because they were in 5th grade, and her focus was not on creating a spreadsheet.
