Surely computational thinking would be a component, but I'm more interested in the entire process of moving from concrete to abstract. <br /><br /><b>@Frank</b><br />Sounds interesting. And right in the wheelhouse of what I'm talking about. It's almost scary how close these two ideas are.David Coxhttps://www.blogger.com/profile/06277427735527075341noreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-50386902251248388272012-04-17T13:34:56.152-07:002012-04-17T13:34:56.152-07:00Hi David,

To exemplify effective instruction, the course is taught using a robust pedagogy, Modeling Instruction.<br /><br />In 2001 the U.S. Department of Education recognized ASU's Modeling Instruction Program as one of two EXEMPLARY K-12 science programs in the nation.<br /><br />Content of an entire semester course is reorganized around basic models to increase its structural coherence. Participants are supplied with a complete set of course materials (resources) and work through activities alternately in the roles of student or teacher.<br /><br />The Modeling Method is introduced as a systematic approach to design of curriculum and instruction. The name Modeling Instruction expresses an emphasis on making and using conceptual models of physical phenomena as central to learning and doing science.<br /><br />Mathematics instruction is integrated seamlessly throughout the entire course by an emphasis on mathematical modeling.<br /><br />Student activities are organized into modeling cycles that engage students systematically in all aspects of modeling. (Specifics of the modeling cycle are at http://modeling.asu.edu/modeling-HS.html.) The teacher guides students unobtrusively through each modeling cycle, with an eye to improving the quality of student discourse by insisting on accurate use of scientific terms, on clarity and cogency of expressed ideas and arguments. After a few cycles, students know how to proceed with an investigation without prompting from the teacher. The main job of the teacher is then to supply them with more powerful modeling tools. Lecturing is restricted to scaffolding new concepts and principles on a need basis.Frank Noschesehttps://www.blogger.com/profile/16584042587600632345noreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-15197905682823423802012-04-17T12:42:11.380-07:002012-04-17T12:42:11.380-07:00Thought-provoking questions! My school has a "...Thought-provoking questions! My school has a "model" similar to what you describe, with math and science paired in the earlier grades. In practice, I have seen it play out quite differently from the philosophy with which it was designed. Mostly, "math" in this situation gets relegated to 'the formulas we use to solve scientific problems.' Your vision sounds much deeper.Anonymousnoreply@blogger.com
