Slide 1

Surveying the Effectiveness of a Science and Mathematics Teacher Development Program through Use of Virtual Comparison Groups John Cronin, the Kingsbury Center at Northwest Evaluation Association Jeff C. Marshall, Clemson University Y. Xiang, the Kingsbury Center at NWEA NARST 2009 Conference

Slide 2

Challenge Context: by expanding the amount and nature of request based direction being encouraged, we expect that understudy accomplishment will likewise increment. Objective: to discover strong measures of understudy accomplishment that sufficiently control for jumbling factors.

Slide 3

Professional Development Overview Yearlong PDI for center school math and science educators 2 accomplice school for every year 8 days in summer 4 days follow-up amid the year perceptions and collaborations with individual instructors on a week by week premise PDI-2—second year administration establishment to empower supportability in the schools

Slide 4

Strengths of Using MAP is adjusted to state benchmarks in arithmetic and science (limits commotion presented when appraisal is not all around adjusted to the learning goals). Single form of MAP is utilized all through our state (grants utilization of results crosswise over locale). Prescient legitimacy between the MAP appraisal and state evaluations is for the most part very high (Cronin, Kingsbury, Dahlin, Adkins, & Bowe, 2007; Northwest Evaluation Association, 2005a). Guide is a versatile appraisal (NWEA, 2003). It likewise makes it less demanding to study sub-spaces of a substance zone, on the grounds that a gathering of a few hundred understudies will give adequate quantities of thing reactions on a substantial exhibit of things to deliver rich, significant outcomes. Outline a Rasch-scaled (Smith, 2001) thing pool as opposed to a scaled test frame. Outline a cross-review scale with strong development standards (NWEA,2005b). This encourages more exact estimation of understudy development crosswise over time.

Slide 5

Evaluation Design Study Group Composed of understudies who are educated by taking an interest region instructors (huge different, urban locale) who take an interest in the PDI. New accomplices of educators will be taken after as extra review bunches. Two Comparison bunches #1: understudies from partaking locale educators who did not take an interest in the PDI. #2: a Virtual Comparison Group of understudies coordinated to the understudies of the review bunch teachers. 

Slide 6

Criteria for VCG (Virtual Control Group) Each review gather understudy coordinated to 51 virtual understudies. (21 understudies in VCG least) Each VCG understudy must have a general scaled score inside one purpose of their review amass understudy. have been tried inside +/ - 7 days of their review assemble understudy. have originated from a school with a Free and Reduced Lunch cooperation rate that is inside 5% of the review gathering understudy's school. originated from a school with the same urban/country assignment. have an indistinguishable sexual orientation and ethnic assignment from the review assemble understudy.

Slide 8

Power of Design Pre-post intercession estimation of the review assemble helps controls for any impact presented by the review gathering educators' earlier execution. Pre-post mediation estimation of the understudies' of non-taking an interest instructors controls for a school or educational system impact. Utilization of Virtual Comparison Groups controls for impacts that may be a result of change in the understudy associates. Proceeded with accumulation of information for a long time after finishing of the program checks whether any influence found for the program is steady. licenses examination of whether there is a "J-bend" impact related with this sort of mediation (Erb & Stevenson, 1999). On the off chance that the change is powerful, understudy results will enhance over the long haul, gave that adequate time is permitted to conquer the J-bend impact (Yore, Anderson, & Shymansky, 2005).
