Mathematical Proficiency for Teaching SCASD 7-12 Math Department Inservice 10/28/2009
Mathematical Proficiency for Teaching • Being able to help someone else know and do mathematics. • Establishing a substantial and continually growing proficiency in mathematics for oneself as a teacher. • Effectively helping one’s students develop mathematical proficiency.
Proficiency in the Mathematical Work of Teaching • Probe mathematical ideas • Access and understand the mathematical thinking of learners • Know and use the curriculum • Assess the mathematical knowledge of learners • Reflect on the mathematical problems of practice
Proficiency in Mathematical Activity • Recognize structure and conventions • Connect within and outside the subject • Represent • Constrain and extend • Generalize • Model • Exemplify • Define • Justify
Proficiency in Fostering Mathematical Goals • Conceptual Understanding – connections – knowing why • Procedural Fluency – flexible, efficient, accurate • Strategic Competence – problem solving • Adaptive Reasoning - explain & justify • Productive Disposition – sees meaning – feels capable • Historical and Cultural Knowledge
Focus A focus presents a particular aspect of mathematical knowledge for teaching at the secondary level that is relevant. Mathematical knowledge for teaching includes concepts, processes, representations, solution methods, interpretations, types of reasoning, properties of mathematical objects, and definitions.
Situation: What Polygons Can Be Circumscribed? In a geometry class, after a discussion about triangles, a student asked, “Can you circumscribe a circle about any polygon?”
Misconceptions What misconceptions are likely for the foci we have just discussed?
Fostering Mathematical Goals What might teaching look like if we want to foster procedural fluency, conceptual understanding, strategic competence, adaptive reasoning, and productive disposition?
Mathematical Activities What mathematical activities might take place? • Recognize structure and conventions • Connect within and outside the subject • Represent • Constrain and extend • Generalize • Model • Exemplify • Define • Justify
Proficiency in the Mathematical Work of Teaching • Probe mathematical ideas - see complexity in simple ideas and reduce the complexity without destroying their integrity • Access and understand the mathematical thinking of learners – see the mathematics from a learner’s perspective. • Know and use the curriculum – connection; common misconceptions; multiple approaches • Assess the mathematical knowledge of learners • Reflect on the mathematical problems of practice – reflect on the work of teaching through a mathematical lens.
