Chunking

  1. 1. Chunking by teacherscpd.wordpress.comUnfortunately most students, and many teachers, have a ”folk psychology” view of learning ratherthan a constructivist view, and this is very hard to budge. Folk theory is considered a real obstacle toeffective teaching and learning by renowned theorists such as J. Bruner and Charles Desforges: Folkpsychology assumes: • Knowledge is stuff • The mind is a vessel • Learning is storing stuff • Acquisition only requires listening reasonably attentively, or even just being there. • Assessment is stock taking • Analogies for learning involve transfer rather than constructivism: • The mug is filled by the jug • Teacher as petrol pump attendant filling student’s empty tanks.The use of jigsaws runs counter to the above by using constructivist principles in the classroom. Thebasic premise of the jigsaw idea is modelled on constructivism. Vygotsky developed the term‘constructivism’ . In a nutshell constructivism comes from the standpoint that individuals create theirown meaning when they learn something new. This literally involves the construction of connectionsbetween neurones. Using jigsaws help students construct their own meanings and make their ownconnections so complex ideas can be remembered – learning is about making sense not justremembering.Reproductive tasks are those which require lower levels of cognition such as:Copying a diagramRecalling a definition grouping ARepeating a processIn contrast reasoning requires high levels of cognition. These tasks are those needing:AnalysisSynthesis grouping BEvaluationGrouping A is about remembering (lower order cognition)while B is about reasoning. Grouping B is high order thinkingan absolute necessity for higher A level grades. These twogroupings can be seen in Blooms Taxonomy.Reasoning develops relations between pieces of knowledge.Reasoning is about constructing meaning between differentideas and jigsaws help with this process in two ways.
  2. 2. Chunking by teacherscpd.wordpress.com 1. Meanings – when we understand something it means we can explain it in terms of something else. For example there is no one explanation or interpretation of something. 2. Application or function – is when students have a deeper understanding and can give a relational response to something (rational response is where conflicts and inconsistencies in different pieces of knowledge are identified by the student allowing them to assess the strengths and weaknesses to form a balanced view). In order to achieve point 2 above, students need to recognise patterns or relations between different pockets of knowledge. Chunking has been identified as a mechanism which helps teachers and students as it’s similar to remembering the journey to a destination without necessarily remembering the names of the roads you journey on. Chunking is a method of breaking up reading material into digestible sections. Chunking helps prevent word-by-word reading, which can negatively affect comprehension since the reader may have forgotten the beginning of the sentence by the time he makes it to the end of the sentence. Studies demonstrate that chunked material, or materials that are separated into meaningful related groups of words, improves the comprehension of some readers, especially poor or low-ability readers. Students now use the chunked knowledge and place them into each jigsaw. For example you could have three key areas of knowledge on the three main political parties in the UK. The students would display chunks of their knowledge into a single jigsaw piece. The next task would be for the students to make a link to the next jigsaw piece by summarising the strengths of each political position while using the jigsaw link to find the weaknesses in the opposing argument. The use of jigsaws helps students use Vygotsky constructivist principles to make their own connections between different ideas; in this example comparing different political parties. By allowing students to build their own constructs it is far easier for them to move their cognition into grouping B. Moreover the skills of evaluation and synthesis become more accessible.Critical Thinking Activity [arranged Relevant Sample Verbslowest to highest]1.
