Concept Circle Diagrams: A Metacognitive Learning Strategy To Enhance Meaningful Learning In The Elementary Science Classroom., Connie Sue Nobles
Concept Circle Diagrams: A Metacognitive Learning Strategy To Enhance Meaningful Learning In The Elementary Science Classroom., Connie Sue Nobles
LSU Historical Dissertations and Theses
The purpose of this study was to explore the use of concept circle diagrams, a newly developed metacognitive strategy (Wandersee, 1987), for meaningful science learning. Two research questions were: (a) Do concept circle diagrams enhance the identification and learning of science concepts more than traditional learning methods? and (b) Do concept circle diagrams evolve in quality within and across three sequences of direct explanation, guided practice, and independent practice? This study builds upon earlier research on two important metacognitive strategies, Vee diagrams (Gowin, 1981) and concept mapping (Novak & Gowin, 1984), used in science education. Participants were members of two …
Use Of The History Of Science In A Nonscience Majors Course: Does It Affect Students' Understanding Of The Nature Of Science?, Linda Easley Roach
Use Of The History Of Science In A Nonscience Majors Course: Does It Affect Students' Understanding Of The Nature Of Science?, Linda Easley Roach
LSU Historical Dissertations and Theses
In response to a call for more research into using the history of science to teach the nature of science, a call for curriculum materials for inclusion of the nature of science in undergraduate nonscience majors courses, and in keeping with the nature of science described in the literature, interactive nature-of-science historical vignettes were utilized in a quantitative and qualitative investigation. Interactive nature-of-science historical vignettes employ the interrupted story form and binary opposites involving conflict to generate student participation and spark discussion about the nature of science. They were utilized as an experimental technique in a university level, introductory nonscience …
Visual Transformations In Symbolic Elementary Algebra., Thomas Harold Awtry
Visual Transformations In Symbolic Elementary Algebra., Thomas Harold Awtry
LSU Historical Dissertations and Theses
Competence in algebra requires knowledge of parsing and transformations. The parsing component specifies the structure of algebraic expressions based on conventional operation hierarchies. The transformational component specifies the real number properties used to transform algebraic expressions into equivalent forms. In standard models of mathematical cognition, both components are conceived as strictly propositional domains (e.g., Anderson, 1983a). Kirshner (1989b) demonstrated that parsing knowledge initially is apprehended in a visual (non-propositional) modality. This dissertation extends that visual analysis beyond parsing to the transformational component. It is proposed that transformations range on a continuum from highly propositional (e.g., x(y$\sp{-1}) = ({\rm x \over …
Toward Understanding Post-Structuralism And Curriculum., Wen-Song Hwu
Toward Understanding Post-Structuralism And Curriculum., Wen-Song Hwu
LSU Historical Dissertations and Theses
This dissertation describes extensions of post-structuralism in contemporary curriculum discourses. Post-structuralist thought is mainly associated with the seminal work of Michel Foucault, Jacques Derrida, Gilles Deleuze, Jean-Francois Lyotard, and Michel Serres. Post-structural criticism and analysis challenge prevailing structuralist approaches and question the fundamental assumptions upon which these approaches rest. A key assumption of structural approaches is that all phenomena are constituted by an underlying structure. In curriculum, these structural assumptions (often scientific) remain unacknowledged and thus are immunized against criticism; rather, they are incorporated into the preferred structural analyses, interpretations, and organizations promoted by the promise of order and rationality. …
