Transcript of Bansho

What is Bansho? Range of Purposes Bansho in Action Bansho in Ontario Benefits of Bansho Blackboard Plan Students use mathematical expressions, numbers, letters and mathematical symbols, figures, graphs, algorithms and labelled diagrams. Bansho is Japanese for 'blackboard' Keeps a record of the lesson
Reminds students what they need to do and think
A visual aid to compare, contrast, and discuss student ideas
Models effective organization and develops note-taking skills
Organizes student thinking, fosters new ideas, and promotes a deeper understanding of mathematical concepts

(Yoshida, 2002) Bansho Sort student work based on the answers students produced or by the model of representation that each group used. Post key words, problems and strategies from the 3-Part lesson on the blackboard from left to right
Student solutions are categorized and labeled like a graph
Student solutions are annotated to highlight strategies, vocabulary, key concepts, representations and symbols
Student work from previous lessons acts as an anchor chart for following lessons Students observe the mathematical thinking of peers
Students “see their own thinking in the context of the similar thinking of others” (Professionally Speaking, March 2006)
Students connect to their learning and enhance their learning by understanding other methods
Students share, discuss, contrast, and compare their ideas
Pressure from grades/scores is absent A learning tool for mathematics “Blackboard is used to show the flow of the lesson process and to connect parts of the lesson coherently together in order to build student understanding” Everything is shown on the blackboard which creates a visual display to organize student thinking! All thoughts are accepted and discussed! Nothing is erased that has been written on the board because “they have strategically selected and recorded mathematical details and annotations that capture the mathematical thinking of students." Students gain a better understanding of a variety of strategies and make connections between all answers. (Kathy Kubota-Zarivni from The Literacy & Numeracy Secretariat) Rosso Bansho! Below is a clip of Bansho in action at an Ontario school: (Yoshida 2003) (Shimizu, 2007; Stigler & Hiebert, 1999; Takahashi, 2006; Yoshida, 2002 from Capacity Building Series, Special Edition #17) (Capacity Building Series, Special Edition #17)
