THIS FILE ALSO INCLUDES A NUMBER OF VARIABLES DERIVED FROM DATA IN THE AB AND BC CONGRUENCY FILES (GR2.MOLRELAB AND BC). MANY OF THESE VARIABLES REFLECT OBSERVED TIME SUMMED OVER OBSERVATION DAYS.

THE PREVIOUSLY PRESENTED LOG DATA (MT1AB-MT15AB) HAVE NOT BEEN ADJUSTED FOR THE TEACHER'S TENDENCY TO OVER- OR UNDERESTIMATE ALLOCATED TIME. ACAT23 PROVIDES AN ADJUSTMENT CO- EFFICIENT, BY TEACHER BY STUDENT, WHICH ENABLES THE USER TO OBTAIN A MORE ACCURATE RECORD OF ALLOCATED CLASSROOM TIME. ACAT23 WAS DERIVED FROM VARIABLES IN THE GR2.MOLRELAB AND BC (CONGRUENCY) FILES. ACAT23 WAS BASED ON AC LEVEL DATA IN ORDER TO OBTAIN A MORE STABLE ESTIMATE OF TEACHER TENDENCIES. ACAT23 SIMPLY REFLECTS THE PROPORTION OF THE OBSERVER'S RECORD OF ALLOCATED TIME TO THE TEACHER'S RECORD OF ALLOCATED TIME. MORE SPECIFICALLY, ACAT23 EQUALS: OBSERVED TIME IN "MATCHED MATH" SUMMED OVER THE AB AND BC PERIODS, DIVIDED BY THE TEACHER'S (LOG) TIME IN MATCHED MATH OVER THE AB AND BC PERIODS. BY VARIABLE LABELS, ACAT23= ACO23 DIVIDED BY (SLMO23AB + SLMO23BC). THE NOMINAL 23 IN THE VARIABLE LABELS IDENTIFIES THE CONGRUENCY TIME CATEGORY: MATCHED MATH (MM).

THIS IS THE VARIABLE THAT WAS USED IN ANALYSES OF STUDENT ENGAGEMENT. ACE23 IS BASED ON AC LEVEL OBSERVATION DATA AND WAS DERIVED FROM VARIABLES IN THE CONGRUENCY FILES (GR2.MOLRELAB AND BC). ACE23 EQUALS: THE TOTAL OBSERVED ENGAGEMENT TIME IN 'MATCHED MATH' OVER THE AC PERIOD DIVIDED BY THE TOTAL OBSERVED (ALLOCATED) TIME IN 'MATCHED MATH" OVER THE AC PERIOD. IT IS SIMPLY THE RATIO OF OBSERVED ENGAGED TIME TO OBSERVED ALLOCATED TIME WHICH YIELDS THE PROPORTION OF TIME THAT THE STUDENT WAS OBSERVED TO BE ENGAGED.

THE PREVIOUSLY PRESENTED LOG DATA (RT1-RT26) HAVE NOT BEEN ADJUSTED FOR THE TEACHER'S TENDENCY TO OVER- OR UNDERESTIMATE ALLOCATED TIME. ACAT14 PRO- VIDES AN ADJUSTMENT COEFFICIENT, BY TEACHER BY STUDENT, WHICH ENABLES THE USER TO OBTAIN A MORE ACCURATE RECORD OF ALLOCATED CLASSROOM TIME. ACAT14 WAS DERIVED FROM VARIABLES IN THE GR2.ROLRELAB AND BC (CONGRUENCY) FILES. ACT14 WAS BASED ON AC LEVEL DATA IN ORDER TO OBTAIN A MORE STABLE ESTIMATE OF TEACHER TENDENCIES. ACAT14 SIMPLY REFLECTS THE PROPORTION OF THE OBSERVER'S RECORD OF ALLOCATED TIME TO THE TEACHER'S RECORD OF ALLOCATED TIME. MORE SPECIFICALLY, ACAT14 EQUALS: OBSERVED TIME IN READING MATCHED (RM) SUMMED OVER THE AB AND BC PERIODS, DIVIDED BY THE TEACHER'S (LOG) TIME IN READING MATCHED OVER THE AB AND BC PERIODS.

THIS IS THE VARIABLE THAT WAS USED IN ANALYSES OF STUDENT ENGAGEMENT. ACE14 IS BASED ON AC LEVEL OBSERVATION DATA AND WAS DERIVED FROM DATA IN THE CONGRUENCY FILES (GR2.ROLRELAB AND BC). ACE14 EQUALS: THE TOTAL OBSERVED ENGAGED TIME IN "READING MATCHED" OVER THE AC PERIOD DIVIDED BY THE TOTAL OBSERVED (ALLOCATED) TIME IN "READING MATCHED" OVER THE AC PERIOD. IT IS SIMPLY THE RATIO OF OBSERVED ENGAGED TIME TO OBSERVED ALLOCATED TIME WHICH YIELDS THE PROPORTION OF TIME THE STUDENT WAS OBSERVED TO BE ENGAGED.
