Implementing Distributed Practice in Statistics Courses: Benefits for Retention and Transfer
(2020-11-18)
The present study investigated the effect of distributed versus crammed practice before a course deadline on the retention and transfer of knowledge, and whether learner characteristics moderate the effect. In Experiment 1, only 41% (N = 38) of the initially enrolled students worked the voluntary but recommended practice tasks. Moreover, markedly fewer students did so in the distributed condition (12%) than the crammed practice condition (29%). In Experiment 2, working the practice tasks was mandatory and more students ...

Learning through Self-Explanation
(2023)
In this dissertation, the effectiveness of learning through self-explanation was examined through a series of experiments. The primary focus was on the acquisition of factual knowledge. Learners' self-explanations were coded and categorized into correct inferences, correct paraphrases, and false utterances.

Access to the learning material enhances learning by means of generating questions: Comparing open- and closed-book conditions
(2020)
Generating questions referring to the learning material is a powerful learning strategy. The present study investigated potential mechanisms behind this effect. Students (N=231) read a text and then generated questions referring to the text in three conditions: (1) open-book (i.e., text accessible), (2) closed-book (i.e., text inaccessible), and (3) cued closed-book (i.e., text inaccessible but keywords provided). After one week, students’ knowledge gain was larger in the open-book and cued closed-book conditions ...

Dynamics of Norms in Decision-Making
(2024-01)
So far, there is a lack of understanding how norms change. The aim of the present dissertation was twofold: (1) addressing differences between change processes of different types of norms and (2) focusing more particularly on how norms are internalized. To study norm dynamics, a multi-method approach was chosen, combining theory, social simulation, and experimental research. In the theoretical contribution, a psychologically grounded conceptual model of norm change and decision-making was presented. Based on a refined ...

Risk Communication during the COVID-19 Pandemic
(2024)
In this PhD project it was aimed to learn about the potential and the challenges of risk communication in systemic risks by conducting applied research during the COVID-19 pandemic. Risk communication plays a crucial role in mitigating these risks by addressing risk beliefs in the population and thereby stimulating behavior change. In the synapsis of this project, however, the prevalence of heterogenous prior risk beliefs in different groups of the population were identified as a major challenge for risk communication ...
