TY - JOUR A1 - Amann, Erwin A1 - Rzepka, Sylvi T1 - The effect of goal-setting prompts in a blended learning environment BT - evidence from a field experiment JF - Economics of education review N2 - Previous literature has shown that task-based goal-setting and distributed learning is beneficial to university-level course performance. We investigate the effects of making these insights salient to students by sending out goal-setting prompts in a blended learning environment with bi-weekly quizzes. The randomized field experiment in a large mandatory economics course shows promising results: the treated students outperform the control group. They are 18.8% (0.20 SD) more likely to pass the exam and earn 6.7% (0.19 SD) more points on the exam. While we cannot causally disentangle the effects of goal-setting from the prompt sent, we observe that treated students use the online learning platform earlier in the semester and attempt more online exercises compared to the control group. The heterogeneity analysis suggests that higher treatment effects are associated with low performance at the beginning of the course.

Sie verbessern die Wohlfahrt und schützen gleichzeitig die Umwelt und das Klima. Dies wird erreicht, indem umweltschädigende Aktivitäten einen Preis bekommen, der möglichst exakt der Höhe des Schadens entspricht. Eine konsequente Bepreisung der externen Kosten nach diesem Prinzip könnte in Deutschland erhebliche zusätzliche Einnahmen erbringen: Basierend auf bisherigen Studien zu externen Kosten wären zusätzliche Einnahmen in der Größenordnung von 348 bis 564 Milliarden Euro pro Jahr (44 bis 71 Prozent der gesamten Steuereinnahmen) möglich. Die Autoren warnen allerdings, dass die Bezifferung der externen Kosten mit erheblichen Unsicherheiten verbunden ist. Damit Lenkungssteuern und -abgaben ihre positiven Lenkungs- und Wohlstandseffekte voll entfalten können, seien zudem institutionelle Reformen notwendig.

Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely to use indirect messages when sanctioning institutions are present. This effect of sanctions on communication reinforces the direct cartel-deterring effect of sanctions as collusion is more difficult to reach and sustain without an explicit agreement. Indirect messages have no, or even a negative, effect on prices.

In dieser Arbeit wurden 5 Potsdamer Grundschulen unter dem Siegel „Schule des gemeinsamen Lernens“ unter dem Aspekt der Barrierefreiheit in technischen Fachräumen untersucht. Die Arbeit erfasst den Ist-Zustand über Einrichtung und Ausstattung technischer Fachräume an oben genannten Potsdamer Schulen und zeigt gleichzeitig verschiedene Fachraumkonzepte auf. Hierzu wurden technische Fachräume zum einen auf barrierefreie Elemente untersucht und zum anderen von WAT-Fachlehrkräften in Hinblick auf ihre Barrierefreiheit bewertet. N2 - The thesis refers to qualitative research in which technical classrooms at Potsdam primary schools were examined for their accessibility in the sense of spatial adaptation to heterogeneous students. 5 specialist rooms were researched by examining them for barrier-free elements and assessing them by specialist teachers. The thesis shows the current state of current technical specialist areas.

BT - the power of platforms to support personalization of public services JF - Journal of Data Intelligence N2 - Digital platforms, by their design, allow the coordination of multiple entities to achieve a common goal. In the public sector, different understandings of the platform concept prevail. To guide the development and further re-search a coherent understanding is required. To address this gap, we identify the constitutive elements of platforms in the public sector. Moreover, their potential to coordinate partially autonomous entities as typical for federal organized states is highlighted. This study contributes through a uniform understanding of public service platforms by providing a framework with constitutive elements, that may guide future analysis. Apart from chance regarding coordination, platforms are well suited to support contextual eGovernment targets. Among them is service personalization. Highly individualized service offerings support targets such as No Stop government. To this end, the paper extends the framework for service personalization in the public sector and exemplifies related aspects using a reference case.
