ThinkBlocks are a tactile manipulative educational tool invented by Derek Cabrera. Cabrera invented the blocks as a way to teach his graduate and doctoral students systems thinking at Cornell University.〔Distributed Knowledge: ThinkBlocks Like an Ergonomic Chair. E-Clips Cornell University. http://www.youtube.com/watch?v=M4qkHbraPOc〕 ThinkBlocks are designed to model concepts and build thinking skills based on the DSRP theory and method of thinking.〔Cabrera, D. and Colosi, L. (2009) ''Thinking at Every Desk: How Four Simple Thinking Skills Will Transform Your Teaching, Classroom, School, and District''. Ithaca, NY: The Research Institute for Thinking in Education. ISBN 978-0979430831〕 This theory posits that four patterns, Distinctions, Systems, Relationships, and Perspectives, underlie all cognition, that they are universal to the process of structuring information, and that people can improve their thinking skills by learning to use the four elements explicitly. Students assign concepts to blocks by writing on them with dry-erase markers, and then associate them with other concepts by using the multi-nesting (multiple blocks inside of blocks), barbell (relational nodes), and looking glass (translucent) properties of the blocks. They were originally white, magnetic dodecahedra in three nested sizes, with one reflective side. In 2012, a new translucent cube-shaped version of the block was introduced. ThinkBlocks were a National Parenting Center Seal of Approval Winner in Fall 2008. ==History== ThinkBlocks (also called DSRP Blocks for the cognitive theory upon which they are based) were invented by Derek Cabrera and debuted at the Chicago International Toy Fair in November, 2007.〔 At that time, ThinkBlocks were sets of opaque white magnetic, dry-erase polyhedra in three different sizes, and sold in sets of 26: 2 large, 8 medium, and 16 small blocks. The large and medium sizes were hollow, such that smaller sizes nest inside of larger ones, and the large and medium sizes also have one reflective side each. In March, 2012, the "Thinking at Every Desk" Facebook page announced the launch of "ThinkBlocks 2.0". These new blocks are translucent non-magnetic cubes and were redesigned, in part, to work in parallel with a diagramming technique called DSRP Diagrams. Like the version 1.0 blocks, version 2.0 blocks are dry-eraseable and nesting. One large 2.0 block fits 8 medium blocks, which in turn fit 8 small blocks. Large blocks are 5 cu. in., medium blocks 2 cu. in, and small blocks 1 cu. in. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ThinkBlocks」の詳細全文を読む スポンサード リンク
