Constructionism is a theory of learning that is a process in which people construct their own knowledge and understanding the world around them in which they develop understanding and demonstrate their learning by building artifacts (Orey, 2001). Constructionism is echoed in Problem Based Learning (PBL) by the creation of a student-centered learning environment and emphasis on artifact creation based on authentic and real life experience with multiple perspectives (Orey, 2001).
When thinking about generating and testing
hypothesis, there are similarities in the process that teachers can use which
include system analysis, problem solving, experimental inquiry, and
investigation (Pitler, Hubble, & Kuhn, 2012), and the instructional
strategies of PBL which include planning, creating, and processing (Orey,
2001). The two strategies blend together
very well to present a well define lesson.
In the problem solving process of generating and testing hypothesis
there is identifying the goal, describing barriers, identify solutions, trying
the solutions and explaining your hypothesis (Pitler et al, 2012). This is similar to part of the planning and
creating strategies of PBL. With regard
to planning, there is the inquiry portion in which includes formulating goals,
plan procedures, and debate ideas. When in the creating phase there is analyzing
data which include making predictions plan experiments and collect data. There
is also collaborating with others in the creating phase where the learner
communicates ideas and findings to others (Orey, 2001).
One idea I have to include these strategies is to introduce a flow chart
in my exploration lessons. I have a
series of lessons that require the students to explore, experiment, and create
an artifact with a set amount of materials. Some of these include creating a paper tower
with one sheet of paper and 12
inches of tape, another is a straw tower that can support
a tennis ball with only 15 straws and no tape, and a sail car with 12 straws, 12 inches of tape, one
sheet of paper and choice of pre-determined set of wheels. Over the years I
have added to these lessons to make it more complex and meaningful to the
students. I added a sketch which evolved to a detailed design, a hypothesis on the functionality or the
expectation of final product, and internet research to explore structures and learn
any building tips to aid them in their project.
Now I want to add a flow chart, using an internet diagramming tool like Cacoo, as a graphical record of their thought process to explain
how they got their final product. I want
something they can look back on and share with others their successes or challenges
on how they created their artifact. It would be a work in process detailing the
process they took in creating their product.
Every time something did not work out they would expand their chart,
explain the changes they made, then cycle back into the flow and continue with
the project. This would be repeated
until they come up with their final product.
It seems like a lot of work, but these projects are done in groups. Hopefully
responsibilities are divided equally amongst the members to ensure no one
person is overwhelmed.
