Introduction

Welcome to the *Thinking About Mathematics Instruction* (*TMI*) *Leadership Content Knowledge Elementary and Middle School
Principals’ Survey* website.
This survey is the cornerstone of a research project (NSF Grant EHR-0335384) to investigate elementary and middle school principals’ leadership content knowledge (LCK) for mathematics.
LCK relates to principals’ knowledge of mathematics for teaching and their ideas about the nature of mathematics learning and mathematics instruction. This site describes how we used
the survey and how we scored and coded the results in our work. It includes the contents of the survey itself as well as coding
schemes for analyzing the qualitative aspects of the data on LCK that the survey provides. (If you are interested in principals and other administrators at the secondary level,

measure the LCK of secondary administrators.)

The original purposes of the TMI survey were to help formulate a picture of the LCK of the national sample of elementary and middle school
principals who participated in our study and to ascertain what can be learned about the LCK of a sub-group of these principals from efforts to improve it through a
professional development program in mathematics education for elementary and middle school administrators called
__Lenses on Learning__. Developed at EDC with support
from the National Science Foundation (NSF Grant ESI-9731242), Lenses provides principals and other administrators with opportunities both to think through different
orientations toward mathematics learning and teaching and to explore mathematical topics from the elementary and middle school curriculum more deeply than they may
have been able to do previously.

Now that we have finished administering the TMI surveys, we are releasing all items, with the exception of those items that
are part of the Mathematics Content Knowledge for Teaching Section, for use by those who wish to gain an understanding of the LCK of principals with whom they
work. We are not at liberty to release the Mathematics Content Knowledge for Teaching section because it comprises items that are still in use in various other
research contexts. We do, however, provide detailed information about the contents of this section as well as how to
__assemble your own mathematics content knowledge section__.
