The Effect Of Scaffolded Strategies On Content Learning In A Designed Science Cyberlearning Environment, Cynthia Lee Kern

UNLV Theses, Dissertations, Professional Papers, and Capstones

Scientific inscriptions--graphs, diagrams, and data--and argumentation are integral to generating and communicating scientific understanding. Scientific inscriptions and argumentation are also important to learning science. However, previous research has indicated that learners struggle to understand and learn science content represented in inscriptions. Furthermore, when learners engage in argumentation, learning science content becomes secondary to the learning of argumentation skills. This design-based research study is nested within the larger effort to inform the design and development of the 5-Featured Dynamic Inquiry Enterprise design framework (5-DIE) for cyberlearning environments and to advance theory associated with the difficulties learners have with scientific inscriptions and …

Standards-Based Assessment System In A Christian Middle School Science Classroom, David J. Mulder
