Part III. Evaluation Results<br />
Effectiveness Of The NWO Center Research Based Math And Science<br />
Professional Development Programs Geared Towards Pre-Service Pre Service And<br />
In-Service In Service Teachers<br />
The progress of the NWO Center towards fulfillment of its Goal 1 was assessed by examining<br />
the effectiveness of the NWO professional development component. This was accomplished by<br />
triangulating data from six different sources - (1) examining beliefs and practices of the NWO<br />
teachers that they shared on the TBI survey, (2) thematically analyzing the emic session<br />
evaluations data (e.g., written evaluations of the professional development sessions) obtained<br />
from the participants, (3) thematically analyzing the faculty interview data, (4) thematically<br />
analyzing the teacher interview data, (5) summarizing the etic session evaluations data (e.g.,<br />
professional development observations ratings provided by the external observers), and (6)<br />
studying other statistics collected by the NWO Center about different activities (e.g., course and<br />
program modification documents, PD attendance data, MAT credit hour completion data, and<br />
Symposium participant involvement data, etc.). The evaluation results below are organized by<br />
each evaluation question that was researched. Program-specific as well as overall summaries<br />
are provided as appropriate and enabled by the data.<br />

Goal 1 - Evaluation Question 1: What are the beliefs and practices of NWO<br />
participants? How do these beliefs compare for TEAMS, TeachOhio and Other<br />
NWO participants?<br />
TEAMS: The means, F values, and effect sizes of 29 TEAMS teacher responses to the TBI<br />
items are presented in Table 5. Significant changes across time are shaded in grey whereas<br />
medium to small effect sizes are bolded in red. Not all of the significant results were due to a<br />
consistent increase across time. Rather, some of the subscales showed an increase from pre-SI<br />
to post-SI, but then a drop down to baseline levels at the AY posttest. Thus, effect sizes are<br />
important to examine in addition to the statistical significance.<br />
Table 5 shows that moderate to large changes in the positive direction were found pre to post SI<br />
for the total STEBI scores, the total Classroom Learning Environment scores, and three of its<br />
four subscales: Classroom Environment (CE), Teaching Activities & Assessment (TA), and<br />
Instructional Goals (IG). For the total Instructional Practices Inventory scores and one of its two<br />
subscales: Reform Strategies (RS), the moderate effect sizes were found pre to post SI in the
