Constructivist/constructionist learning theories center themselves around the ideas that students are constructing their own learning and understanding through the creation of some type of artifact that can be viewed by others and discussed or reflected upon (Orey, 2001).
Project-based learning tools like Internet search engines, concept maps, word processors, spreadsheets, blogs, wikis, podcasting programs, and graphics programs make implementing the project-based learning strategy simple and efficient. In the first stage of project-based learning, these tools allow students to locate and organize information, and collaborate with peers through the organization and production process. Through the second phase, these tools also allow students to cooperatively create a multitude of projects and present them to their class or peers. The third and final phase of project based learning can utilize these technologies to help students reflect upon and follow up on the projects, editing them and revising the project, based on peer and self-reflection (Orey, 2001).
Project-based learning is a methodology that I am certainly much more familiar with, having used it often in my classroom. However, while contemplating Problem-based learning and thinking about it in conjunction with generating and testing hypotheses, I can see a much broader use for spreadsheets in practical applications. Problem-based learning requires students to think about and solve real life problems. This strategy could be highly effective since “learning is most meaningful and is enhanced when students face a situation in which the concept is immediately applied (Orey, 2001).” While I whole-heartedly agree with this statement, I initially had great difficulty combining this strategy with generating and testing hypotheses. I simply could not see a suitable use for my third grade students. Then, as I began thinking of how spreadsheets allow students to build tables and use formulas to manipulate and change data, I began to see how using this tool could build upon many of our classroom math lessons involving patterns. It could also be used to chart and manipulate possible data in a scientific hypothesis (Pitler, Hubbell, Kuhn, and Malenoski, 2007). Most importantly with this particular strategy, using a real world application or problem would have the greatest impact on my students. For example, students could use spreadsheets to chart the number of bricks needed to complete a patio that has a certain number of bricks in each square foot.
Both of these strategies encourage and require students to build some sort of artifact and construct their own understanding of the content they are learning. Because these strategies are interactive with technology and other students, they help students to create multiple connections to the material they are learning, which makes it much more lasting and meaningful to students.
