Constraints on learning, rather than being unique to evolutionarily privileged domains, may operate in nonprivileged domains as well. Understanding of the goals that strategies must meet seems to play an especially important role in these domains in constraining the strategies even before they use them. THe presente experiments showed that children can use their conceptual understanding to accurately evaluate strategies that they not only do not yet use but hat are more conceptually advanced than the strategies they do not use. In Experiment 1, 5-year-olds who did not yet use the min strategy
This Phase I SEPA proposal supports a consortium of science and education partners that will develop System Dynamics (SD) computer models to illustrate basic health science concepts. The consortium includes Oregon Health Sciences University (OHSU), Portland Public Schools (PPS), Saturday Academy, and the Portland VA Medical Center. SD is a computer modeling technique in which diagrams illustrate system structure and simulations illustrate system behavior. Desktop computers and commercial software packages allow SD to be applied with considerable success in K-12 education. NSF grants to Portland Public Schools have trained over 225 high school teachers in Portland and surrounding areas. Two magnet programs have been established with an emphasis on systems and at least five other schools offer significant systems curriculum. Major components of this project include (1) Annual summer research internships at OHSU for high school teachers and high school students, (2) Development of SD models relevant to each research project, (3) Ongoing interactions between high school science programs and OHSU research laboratories, (4) Development of curriculum materials to augment the use of the SD model in the high school classroom or laboratory setting, and (5) Development of video materials to support the classroom teacher. Content will focus on four fundamental models: linear input/exponential output, bi-molecular binding (association/dissociation), population dynamics, and homeostasis. Each of these models is very rich and may be extended to a broad variety of research problems. In addition these models may be combined, for example to illustrate the effect of drugs (binding model) on blood pressure (homeostasis model). System Dynamics is an exemplary tool for the development of materials consistent with National Science Education Standards. SD was specifically developed to emphasize interactions among system structure, organization, and behavior. Students use these material as part of inquiry-based science programs in which the teacher serves as a guide and facilitator rather than the primary source of all content information; technical writing by students is also encouraged. Finally, these SD materials will provide a coherent body of work to guide the ongoing professional development of the classroom science teacher.
1. Build stepwise a prototype -Virtual Clinical Research Center- (VCRC) for K-12 learners and mentors (diverse peers, experts, and patients) by accessing, mobilizing, and linking the human and physical resources of a prototype national network of Clinical Research Centers (CRC) and translational laboratories through state-of-the-art Telemedicine communication and collaborative technologies and featuring T3 or the 3Ts - Teams, Technologies, Translation - of the Clinical Research Enterprise); 2. Develop the Medical Ignorance Exploratorium (MIEx) as a hybrid K-12 cybercafe-health science museum with key features of a) navigable, game-like, 3D environment including -Isles of Medical Ignorance- and -Questionator,- b) Resource Library, c) Live Performance Theater; and d) Collaboration Space, all to stimulate and guide student-centered inquiry about medical breakthroughs, clinical topics, and sick patients (featuring cyber Q3 or the 3Qs-Questions, Questioning, and Questioners); 3. Evaluate the impact and effectiveness of the curricular and delivery resources and models in SA1 and 2 as well as the dissemination in SA4; 4. Disseminate, embed, and expand the refined Virtual CRC and Medical Ignorance Exploratorium in K-12 schools, the clinical research community, and beyond.
