The
connection between constructionist theory and the instructional strategy of
generating and testing hypotheses is almost seamless. Dr. Orey (Laureate Education, Inc., 2011)
defines constructionism as a theory of knowledge where each individual
constructs his or her own meaning. This
occurs through the processes of assimilation, accommodation, equilibration, and
schema. Everyone has schema (background
knowledge), but each individual’s schema is unique. Additionally, we all try to live in the state
of equilibration, or balance. However,
when we encounter new schema, we are thrown into a state of disequilibration
and need to either assimilate (put the new schema in a current category) or
accommodate (alter current schema to fit reality).
There
are numerous approaches in order to promote constructionist learning in the
classroom: learning by design, project-based learning, problem-based learning,
anchored instruction, and WebQuests.
Underlying all of these approaches is the fact that students are
constructing knowledge and either creating new schema or assimilating new
information into current schema. When
students are constructing this knowledge, they must generate a hypothesis as to
how to solve a problem (or how to create a product). The teacher acts as a facilitator and guide
along this process, but the end product is that the student is the one creating
and assimilating the knowledge.
The
following video shows a perfect example of constructionist theory being applied
in an example of Charlie Brown. In this
example, Charlie Brown wants to understand how a Ferris wheel works. Simply reading about how it works does not
help him understand it, so he makes a hypothesis of how a Ferris wheel works,
and tests it by creating a model. By
creating a model, he is able to understand the way a Ferris wheel works and
understands that his hypothesis was accurate.
He takes this learning into school and his classmates learn that they
are able to apply this theory to many other ways of understanding.
Technology can make problem-based learning and testing hypothesis much easier and attainable for students. Rather than doing many rote calculations, students are able to use spreadsheets to easily manipulate data. Many web resources also allow for students to do simulations that would they would not be able to run otherwise to test their hypotheses and knowledge. As Pitler, Hubbell, Kuhn, and Malenoski (2007) state, most technological applications help teachers use many effective instructional strategies to increase student achievement in one lesson.
In closing, the project and problem-based approach is certainly exciting and it is very easy to see that students will be motivated, engaged, and thinking critically in order to solve a problem. However, I foresee one big issue that was touched on briefly in the articles that I have read, and that is the issue of coverage of standards and time. This type of learning produces great results that students will likely remember for years to come, but it also takes a lot of time. The open-endedness of the approach does not guarantee that students will be led to learn about all the curricular contents and standards. It is sad, but in this day and age we are so focused on the state-wide exams, do we have time for this approach? Glazer (2001) states, “Because the scores of standardized tests are sometimes, unfortunately, used to measure learning and the success of a school, test content and question types send a message to teachers and students about what type of learning is valued” (p. 18). The approach presents students will realistic life-like problems that will help them be successful employees in the 21st century, but there is so much pressure for students to pass the standardized testing before they get there. I know that in my state (Pennsylvania) they are restructuring the state tests to align with the common core. We have been told that they will require higher-level thinking of students, but I’m still not sure that it will align with project and problem-based learning. How do we provide the best of both worlds and give students the opportunities to construct their own knowledge and solve their own problems while preparing them for the tests they have to take?
