This project studies the extent to which a technology-based curricular innovation developed through "robust-design" strategies is effective in increasing students' educational outcomes across a range of challenging classroom settings. Evolving an intervention for extreme scalability - even into contexts in which some of its conditions for success are attenuated or lacking - requires "ruggedizing" its efficacy when parts of its intended enactment are absent. Developing an innovation capable of adaptation into most school sites involves designing interventions that retain a substantial proportion of their effectiveness despite relatively barren settings, such as many urban districts, in which some of the innovation's important conditions for success are missing or attenuated. Under these circumstances, major aspects of an innovation's design will not be enacted as intended by developers, so evolving robust-design strategies and studying the efficacy under inhospitable conditions of interventions produced using these ruggedized strategies is important.This project will assess such a strategy for extreme scalability This project will assess such a strategy for extreme scalability through design-based research on large-scale implementations of a multi-user virtual environment (MUVE) curriculum across a spectrum of contexts. Each year, robust-design methods will draw on the prior implementation's results to develop and study a further ruggedized version with increased effectiveness in extreme conditions. Through this research, the project will develop and validate sophisticated methodologies for determining the sensitivity of the MUVE's impact to four selected, varying contextual conditions (extent of teacher professional development involvement, class size, student previous achievement, and student engagement) and for assessing the MUVE's overall effectiveness. The project will also generate 1) robust-design heuristics for increasing the ruggedness and scalability of technology-based educational innovations, and 2) extreme-implementation strategies for aiding with the enactment of technology-based educational innovations under attenuated or absent conditions of success.

该项目研究了通过“稳健设计”战略开发的基于技术的课程创新在多大程度上有效地提高了学生在一系列具有挑战性的课堂环境中的教育成果。要发展一种具有极端可扩展性的干预措施--即使是在其某些成功条件减弱或缺乏的情况下--需要在其预期实施的某些部分缺失时“强化”其效力。开发一种能够适应大多数学校的创新，涉及设计干预措施，尽管相对贫瘠的环境，如许多城市地区，创新的一些重要成功条件缺失或减弱，但仍保留了相当大一部分有效性。在这种情况下，创新设计的主要方面将不会按照开发人员的意图制定，因此，发展稳健的设计策略和研究在恶劣条件下使用这些强化策略产生的干预措施的有效性非常重要。本项目将评估这种极端可扩展性的策略。跨上下文范围的多用户虚拟环境（MUVE）课程的规模实现。每年，鲁棒设计方法将借鉴先前实施的结果，开发和研究进一步加固的版本，在极端条件下提高效率。通过这项研究，该项目将开发和验证复杂的方法，用于确定MUVE的影响的敏感性，四个选定的，不同的上下文条件（教师专业发展的参与程度，班级规模，学生以前的成绩，学生参与）和评估MUVE的整体效果。该项目还将产生1）稳健的设计策略，以增加基于技术的教育创新的坚固性和可扩展性，以及2）极端实施策略，以帮助在减弱或缺乏成功条件下实施基于技术的教育创新。
