Simulator verification techniques study. Integrated simulator self test system concepts

Software and hardware requirements for implementing hardware self tests are presented in support of the development of training and procedures development simulators for the space shuttle program. Self test techniques for simulation hardware and the validation of simulation performance are stipulated. The requirements of an integrated simulator self system are analyzed. Readiness tests, fault isolation tests, and incipient fault detection tests are covered

Simulation verification techniques study

Results are summarized of the simulation verification techniques study which consisted of two tasks: to develop techniques for simulator hardware checkout and to develop techniques for simulation performance verification (validation). The hardware verification task involved definition of simulation hardware (hardware units and integrated simulator configurations), survey of current hardware self-test techniques, and definition of hardware and software techniques for checkout of simulator subsystems. The performance verification task included definition of simulation performance parameters (and critical performance parameters), definition of methods for establishing standards of performance (sources of reference data or validation), and definition of methods for validating performance. Both major tasks included definition of verification software and assessment of verification data base impact. An annotated bibliography of all documents generated during this study is provided

Technology-supported learning environments in science classrooms in India

The adoption of technology has created a major impact in the field of education at all levels. Technology-supported classroom learning environments, involving modern information and communication technologies, are also entering the Indian educational system in general and the schools in Jammu region (Jammu & Kashmir State, India) in particular. This study, which is the first of its kind in India, reports the use of a modified form of Technology-Rich Outcomes-Focused Learning Environment Inventory (TROFLEI) for assessing students' perceptions of their learning environments in technology-supported science classrooms. Analysis of data from 705 students from 15 classes provided evidence for the reliability and validity of the questionnaire in Indian science classroom settings. The same data also were used for studying gender differences and associations between students' perceptions of their technology-supported learning environments and three learner outcomes (attitude towards science, academic efficacy and academic achievement)
