It actively engages students and teachers in the construction of new knowledge through multiple strategies. With it, teachers take on the role of facilitator and co-constructor with your students.</p> <p>Because we believe youth need and want to take responsibility for their own bodies and their health, we feel it is important to find better ways to help them construct mental models of their bodies that they can use to reason about their world. That is the purpose of this curriculum. In addition, new teaching strategies for helping students in the difficult process of constructing mental models of complex topics have been developed. We hope you will find it useful both in teaching this curriculum and in other areas as well.</p> <p><strong>Go to the Curriculum: </strong> <a href="http://www.cesd.umass.edu/energyinthehumanbody/" title="http://www.cesd.umass.edu/energyinthehumanbody/">http://www.cesd.umass.edu/energyinthehumanbody/</a></p> <p>The <em>Energy in the Human Body</em> curriculum is the result of eight years of research on student learning and teaching strategies that assist students in constructing complex mental models of how their bodies work. It has been developed by a team of researchers and expert teachers in an attempt to find strategies that help students learn important concepts in life science. Students learn about how their own bodies use the energy they get from food. They learn why we breathe in oxygen, and breathe out carbon dioxide. Most importantly, they learn why their bodies are designed the way they are and apply this knowledge to common everyday occurrences. Instead of simply memorizing vocabulary, students learn concepts that will be important in their study of Biology later in their academic career. Students will have a chance to relate structure to function, to understand how the way a part of the body is structured relates to the way it works.</p> <p><em>Supported by grants from the National Science Foundation [ESI-9911401 and REC-0231808] John Clement, PI.

This book documents such methods through the analysis of video tapes of scientifically trained experts thinking aloud while working on unfamiliar problems. Some aspects of creative scientific thinking are difficult to explain, such as the power of analogies, the use of physical intuition, and the enigmatic ability to learn from thought experiments. The book examines the hypothesis that these processes are based on imagistic mental simulation as an underlying mechanism. This allows the analysis of insight ("Aha!") episodes of creative theory formation. Advanced processes examined include specialized conserving transformations, Gedanken experiments, and adjusted levels of divergence in thinking. Student interviews are used to show that students have natural abilities for many of these basic reasoning and model construction processes and that this has important implications for expanding instructional theories of conceptual change and inquiry.</p> <p>Table of Contents:</p> <p><a href="http://people.umass.edu/clement/pdf/ClementCreativeTOC.pdf" title="http://people.umass.edu/clement/pdf/ClementCreativeTOC.pdf">http://people.umass.edu/clement/pdf/ClementCreativeTOC.pdf</a></p> <p>Annotated Table of Contents:</p> <p><a href="http://people.umass.edu/clement/pdf/ClementCreativeAnnotatedTOCf.doc" title="http://people.umass.edu/clement/pdf/ClementCreativeAnnotatedTOCf.doc">http://people.umass.edu/clement/pdf/ClementCreativeAnnotatedTOCf.doc</a></p> http://www.srri.umass.edu/node/520#comments Product Completed CLSG Tue, 14 Feb 2012 20:24:03 +0000 Jang Kreetong 520 at http://www.srri.umass.edu Model Based Learning and Instruction in Science http://www.srri.umass.edu/node/519 <div class="field field-type-nodereference field-field-group-ref"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Group Page:&nbsp;</div> <a href="/clsg">CLSG</a> </div> </div> </div> <p>This book is a collection of chapters by our research team describing new, model-based teaching methods for science instruction.

It is a very significant honor for John and an important acknowledgment of his work."</p> <p>One of Clement's contributions was to uncover learning difficulties experienced by science students. He found that students who could solve problems using complicated formulas sometimes did extremely poorly on very basic qualitative problems. Their responses revealed that these students tended to hold "alternative conceptions" that are opposed to what scientists have found to be true, for example, the incorrect idea that a heavy object falls more rapidly in a vacuum than a light object. He also uncovered a considerable number of positive intuitions students possess that are in agreement with scientific theory and that can be used as starting points for instruction. By using experiments and classroom discussions to first draw out and then contrast these two kinds of beliefs, science teachers can promote students' thinking and inquiry skills as well as their deeper understanding of science topics.</p> <p>In discussing his research, John Clement explained, "This basic research on students' learning difficulties in science education has led to the development of curricula that are now being used by thousands of teachers, underlining the importance of the long term effects of research for changing practices in the field."</p> http://www.srri.umass.edu/node/71#comments CLSG Tue, 27 Nov 2007 19:50:22 +0000 root 71 at http://www.srri.umass.edu Preconceptions in Mechanics http://www.srri.umass.edu/preconceptions_in_mechanics <div class="field field-type-text field-field-subtitle"> <div class="field-items"> <div class="field-item odd"> Lessons dealing with conceptual difficulties </div> </div> </div> <div class="field field-type-nodereference field-field-group-ref"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Group Page:&nbsp;</div> <a href="/clsg">CLSG</a> </div> </div> </div> <p><img src="http://www.srri.umass.edu/sites/srri/files/preconception in math.jpg" class="img-right" width=250 />by Charles Camp and <a href="/clement">John Clement</a>.

College Park, MD: American Association of Physics Teachers. Second Edition 2010.</p> <p>The nine units in this high school physics curriculum focus on areas where students have exhibited qualitative preconceptions --- ideas that they bring to class with them prior to instruction in physics. Research has shown that certain preconceptions conflict with the physicist's point of view. It has also shown that some of these conflicting preconceptions are quite persistent and seem to resist change in the face of normal instructional techniques. The motivating idea for this book is to provide a set of lessons that are aimed specifically at these particularly troublesome areas and that use special techniques for dealing with them. Ideas in the lessons can be used to supplement any course that includes mechanics. <!--break--> Many preconceptions that pose difficulties are not simply random errors, nor are they due to inattention or failure to remember key ideas. To help a student learn physics in areas where there are persistent preconceptions, these lessons use a number of special strategies. Most lessons are built around a target problem (a problem designed to draw out a conflicting preconception that has been shown to be present in many students). Another strategy is the use of anchoring analogies or examples--situations where many students' intuitions are in agreement with the physicist's view. Such an intuition can be developed as a rival to, and eventually predominate over, a conflicting preconception.</p> Product Completed CLSG Sat, 27 Oct 2007 15:49:20 +0000 root 26 at http://www.srri.umass.edu
