electric_teachers | R Documentation |
This dataset describes the baseline and final test scores on a test measuring the knowledge of electric circuits given to teachers who were part of a randomized controlled trial of a professional development program.
The trial had three treatment arms (different approaches to the professional development) and a control arm.
The gain (post score - pre score) for all teachers is the change in the percentage point correct on the test of electric circuit knowledge (we call this "content knowledge").

electric_teachers
A data frame with 233 rows and 7 variables:
Site
character - Site ID (city where teachers were recruited). Randomization occured within site.
T.ID
double - Teacher ID
Tx
character - Treatment group. "D" is control.
TxAny
double - Flag for any treatment (main analysis did not find major differences of PD approach.)
Per.1
double - Baseline knowledge (percent correct)
Per.2
double - Endline knowledge (percent correct)
gain
double - Total gain from pre to post.
Not all treatments were given in a site; PD program was delivered to classes of teachers. Teachers individually randomized to class, but there could be class (or PD teacher) effects.
