It’s interesting in this issue to see how teachers can incorporate inquiry learning into topics such as Bernoulli’s Principle, bridge design, photosynthesis, a beach clean-up program, rocks, paper airplanes, maple seeds, and ponds. The authors show how you don’t need elaborate materials to create learning experiences for students that go beyond cookbook demonstrations and focus on real inquiry and problem solving. The articles describe these investigations and also have advice for teachers who want to include more inquiry in their classes. The articles have lots of real-life classroom examples, and the author share their resources, rubrics, and diagrams.
I followed up on some of the suggested websites:

• Recognizing Inquiry compares three hands-on teaching techniques: guided activity, challenge activity, and an open exploration activity. The the comparison has activities that are on the same topic and use the same materials, but the student outcomes are different, based on which technique is used. This is a chapter from the book Inquiry: 
Thoughts, Views, and Strategies for the K-5 Classroom, published by the National Science Foundation.
• The Institute for Inquiry from the Exploratorium has ideas for professional development in inquiry and formative assessments. But you can click on Our Philosophy for a description of inquiry, a downloadable book Pathways to Learning, and Inquiry Structure, a graphic organizer that shows a process of inquiry.
• Doing Science: The Process of Scientific Inquiry is a set of lessons from the National Institute of Health. These lessons guide students (and teachers) through an inquiry process.
• A continuum from the National Research Council shows essential features of inquiry and how to vary activities to guide students through the process. Where do your classroom activities “fit”?

Efforts to promote inquiry in science have been around for a long time (I remember the discussion in my methods courses eons ago, and it’s always at hot topic at NSTA conferences). So why are we still talking about it? What is keeping us from using more inquiry in K-12 science classes? The Science Scope article Engendering Inquiry discusses some of the perceived barriers to implementing inquiry instruction. Are there others? What do you think?
