In the book Using Technology with Classroom Instruction That Works (Pitler, Hubbell, Kuhn, & Malenoski, 2007) there is a chapter that explores the instructional strategy "Generating and Testing Hypotheses". This particular strategy relates to constructivist and constructionist learning theories by engaging students in complex mental processes. Generating and testing hypotheses require student to compare data, present their data as a graph or advanced organizer, predict, and make decisions. The students role is to develop hypotheses to solve a problem, and find information to support their reasonings. This type of project-based learning is learner-oriented. Again, the teacher is the facilitator or motivator, and informs the students of their objectives and how they will be evaluated (Han & Bhattacharya, 2001).
There are tasks a teacher can use to help students generate and test hypotheses. These tasks are 1)a system analysis 2)problem solving 3)historical investigation 4)invention 5)experimental inquiry and 6)decision making (Pitler, Hubbell, Kuhn, & Malenoski, 2007). I found a website in this week's resources that is perfect for helping my 2nd graders generate a hypothesis, make predictions, and begin to think like a biologist. That website is called Astroventure (http://www.astroventure.arc.nasa.gov/). My class went through different scenarios about what would happen to living things on earth if there was too much heat or not enough heat. They wrote down in their journals what they predicted would happen with each scenario, and after they were finished writing, I read to them what a scientist wrote about the different scenarios. All of my students were engaged in this lesson because it had possible real-world problems in it. If I were teaching a higher grade, this could lead to more problem-based inquiry by researching global warming, and determining if this is an issue that could affect all life on earth.
Constructionism is reflected in project-based learning because it is a student-centered learning environment, an artifact is created, and the learning is based on authentic and real life experiences. Project-based learning involves planning, creating, and processing. These instructional strategies can help increase motivation, problem-solving abilities, research skills, collaboration, and project organization skills.
Technology can help implement constructionist/constructivist practices. First, programs like Excel can make data gathering much easier. Students can spend less time having to do manual calculations to find the statistics or information they are looking for. In this week's reading (Pitler, Hubbell, Kuhn, & Malenoski, 2007), the way it was put was students can spend more time interperting the data rather than gathering the data. Technology such as WebQuests, Powerpoint, simulations, blogs, wikis, voice threads, and podcasts can help promote constructivist and constructionist lessons by providing links to support their arguments, representations of activities, feedback, collaboration, and individualized assistance. Technology is a powerful tool to promote constructionist/constructivist practices in the classroom.
