## About KAT

The ** Knowledge of Algebra for Teaching (KAT)**
research project is an interdisciplinary MSU-based research project. The
research team is led by faculty with collective expertise in mathematics, mathematics
education, research design, psychometric analysis, and secondary school
mathematics teaching and curriculum, with the support of research collaborators
around the country. KAT has three main objectives:

**1. Instrument Design:** To develop items and
design reliable and valid instruments to measure knowledge in large scale
settings for teaching algebra. The instruments will be used with preservice and
in-service algebra teachers.

**2. Framework Validation**: To produce an
empirically validated and comprehensive framework for knowledge for teaching
algebra.

**3. Status Study of Teacher Knowledge:** To study
the status and variation of knowledge for teaching algebra among preservice and
in-service teachers from across the nation.

**Intellectual merit of the proposed activity:**
We will contribute an empirically validated and comprehensive framework for
knowledge for teaching algebra at the secondary school level, together with
items and assessment instruments to measure this knowledge in large-scale
settings. The result will be clarification and description of teacher knowledge
in a crucial and problematic area of the K-12 mathematics curriculum.

**Broader impacts resulting from proposed activity:**
The items and assessment tools developed here will be of value for teacher
educators, mathematicians who prepare teachers, designers of professional
development, and evaluators interested in teacher learning in the area of
algebra. Ultimately this work could have substantial impact on the improvement
of secondary school algebra teaching and learning.
