In the German Weimar Republic of the 1920s, the field of economic science found itself in a crisis environment beyond the limits of its understanding. Very few contributions from academia found their way into practice, and thus the limited interplay between the two was of little consequence. During this era, universities responded by introducing various new approaches to make the teaching of economics more relevant to practice. In many universities, this included the participation of practitioners as lecturers and examiners. In addition, Professor Wilhelm Kähler of the University of Greifswald organised field trips within the province of Pomerania so that students could see economics in practice and better grasp its real‐world peculiarities. In this paper, the historical records of these excursions, as recorded in a log, are analysed and insights gained from the numerous teaching visits to companies, welfare institutions, organisations and associations as well as to municipalities, housing developments and infrastructural establishments. The paper concludes with an examination of how practical relevance in university teaching subsequently shifted during the Nazi era.

在1920年代的德国魏玛共和国，经济科学领域陷入了超出其理解范围之外的危机环境。学术界的贡献很少能付诸实践，因此两者之间有限的相互作用几乎没有影响。在这个时代，大学通过引入各种新方法来做出回应，以使经济学的教学与实践更加相关。在许多大学中，这包括从业人员作为讲师和考官的参与。此外，格赖夫斯瓦尔德大学的威廉·凯勒教授在波美拉尼亚省组织了实地考察，使学生可以在实践中了解经济学并更好地掌握其现实世界的特点。在本文中，这些旅行的历史记录，如记录在日志中，通过对公司，福利机构，组织和协会以及市政，住房开发和基础设施的多次教学访问，进行了分析并获得了见解。本文最后考察了纳粹时代后来大学教学中的实用意义如何转变。
