Four Types of Inquiry

01/02/2009

I came across this great article in International Journal of Science and Mathematics Education titled “Facilitating Chemistry Teachers to Implement Inquiry-Based Laboratory Work” (2007, 6: 107 – 130).  Basically, Dr. Derek Cheung implemented inquiry labs into seven classrooms in Hong Kong.  Cheung,  a Associate Professor in the Department of Curriculum and Instruction at The Chinese University of Hong Kong, inserviced the teachers on inquiry and met several times with them throughout the research.

My goal next semester is to implement POGIL activities, inquiry lab work, and practical tests.  I have focused by reading on POGIL and I felt that this would be a great source for inquiry labs.  It was!  I wanted to share some of the major points of the article.

There are four levels of inquiry:

  1. Confirmation Inquiry – verifying concepts by following a procedure
  2. Structured Inquiry – following a procedure to find an answer
  3. Guided Inquiry – Teacher provides a question, students design an experiment to find answer
  4. Open Inquiry – Students ask the question, then find the answer

Cheung recommends that most of class time should be spent in guided inquiry. This also fits with the POGIL approach, but focusing on the laboratory.

 He then gives six criteria for implementing these labs:

  1. The laboratory work should be designed as a guided inquiry rather than an open inquiry
  2. The guided inquiry must engage students in solving real-world problems
  3. The solution to the guided inquiry should not be predictable
  4. The teacher should require a few groups of students to present their experimental plan orally so that a feasible procedure for collecting data can result from a consensus approach
  5. Teacher questioning is critically important during student oral presentations
  6. Assessmesnt criteria must be given to students in advance

I think these two lists provide a decent framework for creating an inquiry based chemistry classroom.  I hope to focus my classroom within the structured inquiry and guided inquiry bands.  However, I hope to implement one or two open inquiry labs.

I also found some other good information from Dr. Cheung concerning inquiry lab examples and multiple choice assessments.
