Notes: [Auszug] WHEN Bardeen and Brattain announced their VV discovery of transistor action in 1948, it was foreseen that much research and development would be needed before widespread applications became possible. What has followed, however, has been on a scale many times greater than generally expected. The ...

Notes: Abstract One way to better understand the difficult instructional issues associated with the integration of computer technology in classrooms is to analyze the implementation of computer technology. This study developed and validated a measure for examining the quality of implementation of an Integrated Learning System (ILS). The measure was used to analyze ILS implementation and determine if there were differences in the operational patterns of teachers implementing an ILS and identify implementation practices of teachers that indicated implementation fidelity. The measure indicated which teachers were high fidelity implementers and which implementation practices distinguished high fidelity implementers.
