This study explores how a variety of technology tools and systems were employed to support the internal formative evaluation of the design, construction, and implementation of a grades K-4 space mission simulator. The new simulator for early elementary age youth builds on the success of the existing Challenger Learning Center simulator, which has served more than 100,000 students and teachers. The evaluation summarizes the results of a process approach that documented the planning, design, development, and implementation strategies from the assessment of facilities for restructuring to designing lighting, furniture, program activities, and the scenario context. The discussion includes a description of media tools and collaborative systems used to collect and organize the documentation, decision-making, and outcomes of formative testing. The presentation will show how media tools were used to document design, construction, implementation, formative testing processes associated with the physical and programmatic components of the simulator development. #Educational #EvaluationUse #2010Conference #Technologies #Prek-12EducationalEvaluation #Ruberg #NASA #STEM #inquiry #Center #for #HowTo #Research,Technology,andDevelopmentEval #K-4
