Using A Paradigm Shift To Teach Neurobiology And The Nature Of Science—A C.R.E.A.T.E.-Based Approach, Sally G. Hoskins
Using A Paradigm Shift To Teach Neurobiology And The Nature Of Science—A C.R.E.A.T.E.-Based Approach, Sally G. Hoskins
Publications and Research
Decades ago, classic experiments established the phenomenon of “neural induction” (Spemann and Mangold, 1924; Holtfreter, 1933). It appeared clear that amphibian ectoderm was pre-programmed to form epidermis, and that the neural phenotype was induced by a chemical signal from mesoderm. The “ectoderm makes skin, unless induced to make nervous system” model appeared in many textbooks. This interpretation, however, was not simply incorrect but 180 degrees out of alignment with the actual situation. As subsequently demonstrated, the default state of amphibian ectoderm is neuronal, and the expression of the epidermal phenotype requires cell signaling (Hemmati-Brivanlou and Melton, 1992; 1994; 1997). In …
Teacher As Designer: A Framework For Teacher Analysis Of Mathematical Model-Eliciting Activities, Margret A. Hjalmarson, Heidi Diefes-Dux
Teacher As Designer: A Framework For Teacher Analysis Of Mathematical Model-Eliciting Activities, Margret A. Hjalmarson, Heidi Diefes-Dux
Interdisciplinary Journal of Problem-Based Learning
The study investigated tool development by three middle school mathematics teachers. The tools they designed were intended to support the use of model-eliciting activities (a form of instruction related to problem-based learning) and particularly the students’ presentations of their solutions for the whole class. The study examined the design and purposes for the presentation tools and resulted in a framework for categorizing teachers’ purposes for tools.The framework addressed the unit of analysis for the tools (individual students or groups of students) and the nature of teachers’ purposes for the tools. Design research was used as a theoretical perspective for conducting …
Models And Paradigms In Kuhn And Halloun, Paul J. Wendel
Models And Paradigms In Kuhn And Halloun, Paul J. Wendel
Education Faculty Scholarship & Creative Works
In Modeling Theory in Science Education, Halloun (2004) adopts the word ‘paradigm’, but his use of the term is radically different from that of Kuhn. In this paper, I explore some of the differences between Kuhn’s paradigms and Halloun’s paradigms. Where Kuhn’s paradigms are public, community-defining exemplars of practice, Halloun’s paradigms are private, individualized ways of thinking. Where Kuhn writes of the paradigm shift as a revolutionary, vision-altering conversion experience, Halloun writes of a gradual evolution from one way of thinking to another and an easy back-and-forth switch between paradigms. Since …
Do You Want To Know What I Learned? Using Informational Trade Books As Models To Teach Text Structure, Sylvia Read, D. Ray Reutzel, P. Fawson
Do You Want To Know What I Learned? Using Informational Trade Books As Models To Teach Text Structure, Sylvia Read, D. Ray Reutzel, P. Fawson
Teacher Education and Leadership Faculty Publications
A brief narrative description of the journal article, document, or resource. Informational text is an important resource for classroom teachers that places unique comprehension demands on young students. Research on teaching expository text structure to young children shows that explicit instruction improves student comprehension. This practical article addresses how to use "well-structured" expository trade book titles to teach text structure. A lesson plan template and an extended example of an explicit lesson on order/sequence are provided.
