Subject: [edstat] Unit of AnalysisHi 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
