The measures of
an analysis of their
control CDC group.
,
effectiveness ci the two experimental CDC groups was
final course grade performance in comparison to the
Xl1 caiculations were performed using statistical packages available
in the FIAT0 I\’ computer-based teaching system. There are presently four
PLATO IV terminals at Chanute connected to a central computer located at
the Urbana campus of the University of Illinois. The mathematical formulas
nrccssary for any analysis, including those involving unequal n’s, are
included in the analysis programs used. The person raking the analysis is
required only to select the type of analysis desired and input the raw data.
:\nsxers appear on the screen immediately. Thus, it was possible to examine
a great amount of raw data concerning the subjects of the study and receive
back an almost instantaneous readout of the analysis selected.
Overall results obtained from this study are summari-zed in Table 1.
