  • Graphing calculators in college calculus : an examination of teachers' conceptions and instructional practice

    Creator:
    Barton, Susan Dale
    Abstract:
    The study examined classroom instructional practices and teacher's professed conceptions about teaching and learning college calculus in relationship to the implementation of scientific-programmable-graphics (SPG) calculators. The study occurred at a university not affiliated with any reform project. The participants were not the catalysts seeking to implement calculus reform, but expressed...

  • Partnerships between secondary/elementary science teachers and laboratory-based scientists : delineating best practices

    Creator:
    Henderson, Sandra
    Abstract:
    Given the high probability of national and federal research laboratories continuing to sponsor science education partnerships between their staff and classroom science teachers and the dearth of research in this area, this study set out to delineate best practices associated with such partnerships for the purpose of increasing the effectiveness...

  • Analyzing explicit teaching strategies and student discourse for scientific argumentation

    Creator:
    Park, Young-Shin
    Abstract:
    Scientific inquiry in K-12 classrooms tends to be procedural, lacking opportunities for students to gain understanding of how scientific knowledge is constructed through reflection, debate, and argument. Limited opportunity to develop scientific argumentation skills prevents students from practicing the scientific thinking needed to understand the nature of scientific knowledge and...

  • Biology teacher's perceptions of subject matter structure and its relationship to classroom practice

    Creator:
    Gess-Newsome, Julie
    Abstract:
    Current reforms in science education advocate instruction which capitalizes on broad, integrative understandings of a few underlying concepts. Such recommendations imply that science teachers already hold integrated conceptualizations and will use such understandings to guide practice. However, little research exists which delineates the global content understandings of biology teachers (herein...
