  • A multifaceted assessment of adult informal learning at the Hatfield Marine Science Center

    Creator:
    Lynds, Susan E.
    Abstract:
    Authentic assessment of visitor learning in museum settings is a challenging endeavor. Evaluation literature includes very few studies that link adult visitors' behavior to their learning. Multiple data collection methods in a naturalistic environment hold great promise for increasing understanding of informal public education. In 1997, Oregon State University's Hatfield...

  • Investigating teachers' understanding and diagnosis of students' preconceptions in the secondary science classroom

    Creator:
    Morrison, Judith A.
    Abstract:
    A large amount of research has been conducted that establishes that students of all ages hold conceptions about a variety of science topics that are not in line with accepted scientific beliefs. These preconceptions have been identified in a variety of ways in research situations; this study focused on how...
