Intervention studies typically target a focused aspect of language learning that is studied over a relatively short time frame for a relatively small number of participants in a controlled setting. While for many research questions, this is effective, it can also limit the ecological validity and relevance of the results for real-life language learning. In educational science, large-scale randomized controlled field trials (RCTs) are seen as the gold standard method for addressing this challenge—yet they require intervention to scale to hundreds of learners in their varied, authentic contexts.We discuss the use of technology in support of large-scale interventions that are fully integrated in regular classes in secondary school. As an experimentation platform, we developed a web-based workbook to replace a printed workbook widely used in German schools. The web-based FeedBook provides immediate scaffolded feedback to students on form and meaning for various exercise types, covering the full range of constructions in the seventh-grade English curriculum.Following the conceptual discussion, we report on the first results of an ongoing, yearlong RCT. The results confirm the effectiveness of the scaffolded feedback, and the approach makes students and learning process variables accessible for the analysis of learning in a real-world context.

扩大干预研究以调查学校现实生活中的外语学习

干预研究通常针对语言学习的一个重点方面，该方面是在相对较短的时间内为受控环境中相对较少的参与者进行研究的。虽然对于许多研究问题来说，这是有效的，但它也会限制结果在现实生活中的语言学习的生态有效性和相关性。在教育科学中，大规模随机对照现场试验 (RCT) 被视为应对这一挑战的黄金标准方法——但它们需要干预才能在数百名学习者的不同、真实的环境中扩大规模。我们讨论了技术在支持完全融入中学常规课程的大规模干预措施。作为一个实验平台，我们开发了一个基于网络的工作簿来取代在德国学校广泛使用的印刷工作簿。基于网络的 FeedBook 为学生提供关于各种练习类型的形式和意义的即时反馈，涵盖了七年级英语课程中的所有结构。在概念讨论之后，我们报告了一个持续的、为期一年的第一个结果随机对照试验。结果证实了支架式反馈的有效性，并且该方法使学生和学习过程变量可用于在现实世界环境中进行学习分析。我们报告了一项持续的、为期一年的 RCT 的初步结果。结果证实了支架式反馈的有效性，并且该方法使学生和学习过程变量可用于在现实世界环境中进行学习分析。我们报告了一项持续的、为期一年的 RCT 的初步结果。结果证实了支架式反馈的有效性，并且该方法使学生和学习过程变量可用于在现实世界环境中进行学习分析。
