“…Nineteen studies [34,36,38,42,45,46,49–51,53–55,57,59–61,64,65,67] used the most recent version of the CLASS [72], 5 studies [43,48,52,62,63] used an earlier version [73], which did not include the Language Modeling dimension, and 11 studies [7,8,30,31,39–41,44,47,56,58] used CLASS domains (emotional and/or instructional climate) from the earlier version. Since we did not have data on the comparability of scores when these scales were combined vs. analyzed separately we chose the conservative route and tested the Emotional Climate domain separately.…”
