Generating and Testing Hypotheses and Constructionist Learning Theory

Generating and testing hypotheses is the perfect strategy to relate with the constructivist/ constructionist approaches. Six ways this instructional strategy can be used in the classroom include: systems analysis, problem solving, historical investigations, invention, experimental inquiry, and decision making (Pitler, Hubbell, & Kuhn, 2007). These strategies truly correlate to these approaches. In the constructivist approach, the learner actively constructs their own meaning to their learning through their experiences (Laureate Education, Inc., 2011). The constructionist learning theory approach takes this one step further and suggests students learn best when they create an artifact that they share with others (Laureate Education, Inc., 2011). These learning theories are definitely evident in these learning theories and can be easily integrated in project-based learning.

One example of how these six tasks can be integrated in project-based learning and constructionist learning theory is in a science fair project. Last year, my 5th graders took part of a science fair. Students were instructed to pick a project that addressed the science inquire model. Therefore, students had to create an investigation based on a question they were interested in. They had to have one manipulated variable, one responding variable and controlled variables. Before beginning their investigation, students wrote a hypothesis and predicted what they thought would happen in their experiment. Students then kept data and scientific notes on their project for three weeks. Some investigation questions students explored included: “What type of bubble gum blows the biggest bubbles?”, “How are plants growth affected by various liquids?”, “What laundry detergent gets stains out the best?”, etc. Throughout their investigation, I worked with students individually and guided them throughout the process. Students also used Excel and Word tables to organize their data. Many students also learned how to input data into an Excel document and create amazing graphs to display the change in their responding variable in their project. In the end, students also had to analyze their results by writing a scientific conclusion and creating a science display for our science fair. Parents and other students in the school were invited to come to the science fair where students discussed their investigation and findings. This was a very intense and time consuming project, yet a highly effective way we used all of these strategies in our classroom. This was the first year we did a science fair; however, we found that this one project really gave our students a solid foundation on science-inquiry.  In the end, all of the classes that participated in this science fair found the class average of passing our state science test went up over an average of 25% more students passing the test. As a school, our science scores went up from 52% to 78% of students who passed this state test. There is definitely room for improvement, especially since this was the first year we did a science fair. However, we all believe the number one reason for this increase of achievement was because of the science inquiry-based science fair. Students were invested in a problem they chose and really learned the science inquiry model first hand. In the end, they also created an artifact and had to share their findings with others in a science fair setting. Click here to link to my classroom website that has last year’s science fair project.

This is just one example of how generating and testing hypotheses can fit into the constructionist learning theory. I am curious to find creative ways to use these strategies in other subject areas. Does anyone have some clever ideas? I would love to hear them!

    Science is the perfect place for project based learning. They learn many skills in science that they are able to take to their other courses. Excel is a great way to organize information. Did you students have trouble figuring the program out? Or did they catch on rather quickly? That program looks complex and can be complex and I have always wondered what students thought of it. I teach second grade and believe it would be too much for them to take on.
    That is great that your scores soared! What a testament to the work the students put in!

  2. Hi Alli-

    Thank you for the post and comments! I did teach my students how to specifically create and use a table in an Open Office document. I did not teach them Excel or any programs like Excel. Many students used the programs on their own or with their parents. These students created some amazing graphs of their data. This year I hope to do a science fair again and work with Excel with the students. I am not that advanced with Excel, so I will likely have to have the students teach me! :-) As for doing a project like this with second graders, I think you can do it, but super simplified. I know of a school in my district that does a school wide science fair starting at second grade. I am not exactly sure how they implement it, but I am sure they do something much simplier. Good luck!

    Wow, I understand about how this constructivist theory yields great results, but your post brought me back to my 6th grade class when i did I similiar project. I tested how heat is absorbed differently based upon the items color. Through these techniques and construction I still remember the entire project. I can say the same for the year before when we built castles when studing Europe and the year after when i made a video about WWII. These might be the only three lessons I remember from grade school. Cool post! Do you do any other large scale projects?

  4. Thanks Nick! It is those large projects we remember! I remember in 8th grade we had to create our own country. Mine was called Pouchavania and it was an island the shape of a dog head. Dog bones were my currency and when I brought my project home, my dog literally ate my homework! Oh the funny things we remember! I think memories like these are what really helps us create those important connections. It is important for me to give those experiences to my students. Currently, my students are doing a project called, "Apart of Me." In this project, they are either doing a family tree and research or a culture they feel connected to. If you click on my website link in my original post, you can find the project under the homework tab. I decided to do this project because of an inspiration from the diversity class in the spring and because my grandmother died this summer and I wanted to do something to honor her. So I shared tons of pictures and memories of my grandma to my class. I showed them my family tree and went over how to write the essay about their family member or culture. The students now come in every day excited to share something about their family history. One of my students found out she is related to Laura Ingles Wilder, which she was super excited about. This is a project that means so much to them because it is apart of their lives. It was also motivating to them to learn more about their families when they saw my family lines and how much my grandma meant to me. I also do several other projects throughout the year. I think after we finish this project, we will do a problem-based learning project. My district is in a huge debate right now about possibly moving 6th grade to middle school next year and closing an elementary school to save money (my current school is on the chopping block). I want them to make a PowerPoint presentation to the board as a final project about what they think should happen, as doing some research. I think it will definitely be an important project for them. Every year I do different projects based on what the needs of the students are and what I think they would be interested in doing.
