Many early language support programmes have been implemented in ECEC settings over the last years in Germany. Most of them are targeted programmes which have not shown to have longer term beneficial effects. The concept of early language education embedded into daily preschool routines is a child-oriented approach for all children and all age groups. The national programme “core daycare centres language & integration” aimed at promoting early language education embedded into daily routines at 4000 participating centres. In this paper, the longitudinal evaluation study of the programme is described, and the specific methodological challenges and potentials of the evaluation are discussed. The lack of instruments in ECEC research, the nature of pedagogy in ECEC, the autonomy given to the settings and professionals, the lack of control and the interpretation of effect sizes are highlighted as the main challenges. At the same time, the urgent need of such evaluations and the benefits for policy-makers, research, practitioners and the public are explored.

评估德国早期语言教育计划效果的方法挑战

在过去的几年中，许多早期的语言支持计划已在ECEC的环境中在德国实施。其中大多数是针对性的计划，尚未显示出长期的有益效果。嵌入日常学前班的早期语言教育的概念是面向所有儿童和所有年龄段的面向儿童的方法。国家计划“核心日托中心的语言与融合”旨在促进在4000个参与中心的日程中嵌入早期语言教育。本文描述了该程序的纵向评估研究，并讨论了评估的具体方法挑战和潜力。ECEC研究中缺乏工具，ECEC中教学法的性质，环境和专业人员的自主权，缺乏控制和对效应大小的解释是主要挑战。同时，探讨了这种评估的迫切需要以及为决策者，研究人员，从业者和公众带来的利益。
