Project Overview
Background & Purpose: 

Our goal for the project is to further develop the Dimensions of Success (DOS) as a psychometrically refined observation tool for broad use in the OST field. To accomplish our goal, we will:

  • Refine the DOS instrument through iterative data collection, analysis and revision of the protocol with partnering afterschool programs (Phase 1)
  • Scale up our use of the DOS instrument to collect data from a large-scale study to investigate its psychometric properties and its applicability to a wide range of OST science program providers (Phase 2)
  • Refine the training program for DOS use by researchers and practitioner and broadly share the results of our work and the DOS instrument to practitioners, evaluators and researchers in the ISE field (Phase 3).
Setting: 

Our project is located at: 1) Program in Education Afterschool and Resiliency (PEAR) at Harvard University and McLean Hospital; 2) Educational Testing Services (ETS); and 3) Missouri Afterschool Network.

Research Design: 

The research design for this project is comparative and will generate evidence that is descriptive [observational]. The project also collects original data using assessments of learning [achievement tests], observation [personal observation and videography], and survey research [self-completion questionnaire]. We have chosen the Informal Science instructors working with middle school-aged children as our unit of analysis.

Findings: 

Findings will be posted as they become available.
