Subject: [edstat] Unit of Analysis
Hi all,
We have data from a quasiexperimental nonequivalent control group
design.
A treatment group where the teachers are trained and are implementing a
professional development model that involves group and individual
coaching
to use data to identify their students' component reading skills and
target
their teaching interventions to get the missing skills in place. They
use
whole group, small group and individual instruction.
A comparison group of classrooms from demographically similar schools
doing
whatever they normally do.
The students were tested in fall and again near the end of the school
year.
What is the appropriate unit of analysis? And why?
What if in some of the treatment group students were grouped into
skill-based groups across classrooms for reading instruction?
Thanks,
Betty
