Subproject M has a unique status within the research unit FOR 2385, as the project itself does not collect data in primary studies. Instead, the project is responsible for the meta-analytic integration of data and studies, the standardization of data collection, and coordinating the work on the conceptual framework as well as the support for the PhD students. So far, subproject M compiled a set of test instruments that are used in every subproject. In addition, subproject M conducted two meta-analyses with external studies from the research literature. The first of these meta-analyses has been accepted for publication already. Currently, subproject M is gathering and integrating data from the other subprojects in order to answer research questions that span across all the subprojects with a focus on the question of whether effects of scaffolding can be generalized. The results from the meta-analyses validated relationships between variables that are at the core of the conceptual framework of the research unit. For instance, the analyses revealed a medium-sized effect of various instructional support measures on diagnostic competences. Additionally, a large-sized effect of simulation-based learning environments on complex decision-making competences was found. Both meta-analyses showed that the effect of scaffolding is influenced by the prior knowledge of learners. These results motivated the research unit to focus on the adaptation of scaffolding in the second funding period. Therefore, subproject M will further develop the conceptual model of the research unit and conduct research about designing simulations in which scaffolding is adapted to the learners. The main research questions are: What is the relation between various learning prerequisites and types of scaffolding? Which adaptation strategies are most effective? Which process variables mediate the effects of adaptation? Which context variables have an influence? Subproject M contributes to answering these questions in a unique way: It tests the generalizability of the results by working on these questions in a way that spans across the other subprojects. To answer the questions, the meta-analyses with external studies from the research literature will be continued with an extended coding scheme. The integration of data from the whole research unit will be continued, too, using advanced statistical methods: Bayesian network analyses will be used to analyze process data and generalized mixed models will be used to integrate data. Subproject M will also keep its additional tasks of standardizing assessment instruments, collecting data, promoting open science principles, conducting workshops, and communicating results of the group.

子项目M在研究单位FOR 2385中具有独特的地位，因为该项目本身不收集主要研究中的数据。相反，该项目负责数据和研究的元分析整合，数据收集的标准化，协调概念框架的工作以及对博士生的支持。到目前为止，子项目M编写了一套测试工具，用于每个子项目。此外，子项目M对研究文献中的外部研究进行了两项荟萃分析。这些荟萃分析中的第一个已经被接受出版。 目前，子项目M正在收集和整合来自其他子项目的数据，以回答跨越所有子项目的研究问题，重点是脚手架效应是否可以推广的问题。荟萃分析的结果验证了研究单位概念框架核心变量之间的关系。例如，分析显示，各种教学支持措施对诊断能力的中等影响。此外，基于模拟的学习环境对复杂决策能力有很大的影响。两项元分析都表明，脚手架的效果受到学习者的先验知识的影响。这些结果促使研究单位在第二个资助期内重点研究支架的适应性。因此，子项目M将进一步发展研究单元的概念模型，并进行有关设计模拟的研究，其中支架适合学习者。主要的研究问题是：各种学习先决条件和支架类型之间的关系是什么？哪些适应战略最有效？哪些过程变量调节适应的效果？哪些上下文变量会产生影响？子项目M以一种独特的方式回答了这些问题：它通过以一种跨越其他子项目的方式处理这些问题来测试结果的普遍性。为了回答这些问题，将使用扩展编码方案继续对研究文献中的外部研究进行荟萃分析。还将继续使用先进的统计方法综合整个研究单位的数据：贝叶斯网络分析将用于分析过程数据，广义混合模型将用于综合数据。分项目M还将保留其额外任务，即标准化评估工具、收集数据、促进开放科学原则、举办讲习班和交流小组的成果。
