Table 15.2 below shows participant responses on experience using online resources,
experience creating online lessons, advantages of using technology in the classroom.
Comparisons between the pre- and post-survey scores are made with Cohen's d ,
using the pooled estimate of the population standard deviation as the denominator.
Cohen was understandable reluctant to come up with thresholds for something as
complex as social science research but did say that effect sizes of 0.2 are relatively
small, 0.5 are moderate, and 0.8 are large (Cohen, 1988).

As seen in Table 15.2, all responses show increases from pre- to post-survey,
with moderate to strong effect sizes. These results suggest a positive impact of
the workshop experience. When asked about the future use of the IA on the
post-survey, participants reported that they would use the IA in their classroom
( M
=
3.80, SD
=
0.58) and would tell other teachers about the IA ( M
=
3.80,
SD
0.51).
Finally, site-usage statistics show that 35% of participants used the IA during the
2008-2009 school year.

The evaluation of this workshop focused on (a) changes in the amount of experience
using online resources, (b) difficulty in using online resources, and (c) self-report on
the ability to use technology in the classroom.
Table 15.3 shows participants' response (mean, standard deviation, and effect
sizes) on pre- and post-survey items. Results showed that by the end of the work-
shop experience participants reported a strong positive effect size in their experience
creating online lessons, knowing how to effectively use technology in the class-
room, knowing how to effectively teach with technology inthe classroom, and a
