The Context in LMT for LMT-QMI Videocodes • LMT Project follows SII finding that teachers with higher mathematical knowledge for teaching (MKT) had higher- achieving students • Measures MKT through paper-and-pencil multiple-choice items • Develops the construct of MKT • Provides data about professional development BUT: Does achievement on paper-and-pencil measures matter in instruction? We videotaped lessons of a subset of teachers to validate. • 10 teachers • 9 videotaped lessons each, over one year • Interviews
Coding of videotapes • Videocodes cover these domains: • Mathematical content and instructional format • Teacher’s use of mathematical language, representations, explanations • Teacher’s mathematical interaction with student productions • Teacher’s use of mathematics to teach equitably • Videocodes are neutral regarding teaching style (“reform-oriented,” “didactic,” etc.)
Modeling • Red “pies” represent negative numbers • Green “pies” represent positive numbers
Coding Glossary • To code, first decide whether the mathematical element is present (P) or not present (NP). If present, then: • Mark appropriate (A) if the teacher’s use of the element was, for the most part, mathematically accurate and appropriate—it did not distort the mathematics. • Mark inappropriate (I) if the teacher’s use of the element distorted the mathematics or was inappropriate for the grade level. • If not present, then: • Mark appropriate (A) if absence of the element seems appropriate. • Mark inappropriate (I) if absence of the element seems problematic—i.e., the element should have happened.
Use of videocodes • Our findings: • inter-rater reliability of .7 to .85 • teachers’ clinical practice scores and test scores correlation of .75 or higher • Others’ potential use of codes would require: • Shared understandings of the codes • Users with MKT
