Abstract

Although much has been written concerning the techniques and benefits associated with inquiry-based laboratory methods, the use of this approach in both college and secondary school science classrooms is rare. In this article we present one exercise we conduct during summer workshops for in-service secondary school science teachers. This exercise provides a clearer understanding of why the use of verification experiments persists at the secondary school level while at the same time it allows teachers to more closely examine the administrative and pedagogical advantages and disadvantages associated with this approach. Following a discussion of the exercise, we elaborate on the advantages and disadvantages of the verification approach and how they relate to the overall goals of a laboratory experience for students. We conclude with a brief discussion of the steps that might be taken to further disseminate inquiry experiments, as suggested by the results of this exercise.

    • The Effects of Inquiry-Based Instruction on Elementary Teaching Majors' Chemistry Content Knowledge

      Michael J. Sanger
      Journal of Chemical Education2007 84 (6), 1035

      Although science educators have suggested that preservice elementary teaching majors should take chemistry content courses using inquiry-based methods, many college chemistry professors believe that these courses are merely “watered down” versions of ...

    • Sherlock Holmes and the Case of the Raven and the Ambassador's Wife: An Inquiry-Based Murder Mystery

      Nathaniel Grove and Stacey Lowery Bretz
      Journal of Chemical Education2005 82 (10), 1532

      Inquiry-based experiments require students to take an active role in the learning process by having them develop their own procedures and data tables. This shift in responsibility requires students to think for themselves and show what they have truly ...
