Critical research on data visualisations in education has so far mostly focused on the representation of numeric data in dashboards or graphs. Consequently, the question of how schools are made visible and (re)enacted through visual structures on data-mediated interfaces more broadly -- what we call Graphic Data Visualisations (GDV) -- has…

Simplified user interfaces (SUIs) refer to a new design technique in technical communication that simplifies screenshots by removing irrelevant elements and highlighting only the essential information. While there is consensus on the benefits of signaling in multimedia learning, there is currently no empirical evidence on the effects of SUIs on…

The increasing availability of digital tools in science classrooms can provide students with more frequent and easier access to large amounts of data. Large data sets have considerable epistemological potential, as they enable, for instance, the observation of otherwise unobservable phenomena, but it must be assumed that handling them places…

With the "pictorial turn", the picture has gained a new significance as a medium. It is impossible to imagine a digitalized world affected by mass media without pictures. While there are several studies on the impact of pictures in the discourse on climate change in the media, there has been no analysis of the visual representation of…

Previous studies on Bayesian situations, in which probabilistic information is used to update the probability of a hypothesis, have often focused on the calculation of a posterior probability. We argue that for an in-depth understanding of Bayesian situations, it is (apart from mere calculation) also necessary to be able to evaluate the effect of…

This picture-type analysis of front covers of the German magazine "Der Spiegel" starts from the premise that the magazine's front covers convey history narratives that might play an important role in history education. Pupils can learn from them which history narratives dominate public discourse or cultural memory. The article provides a…

The teacher's use of representations is a crucial aspect of instructional quality in mathematics education, given their pivotal role in facilitating mathematics learning. However, in our international research community, perspectives on what constitutes high-quality use of representations may vary. This cross-cultural study aims to explore whether…

The intricate relationship between representational competence and content knowledge in organic chemistry has been widely debated, and the ways in which representations contribute to task difficulty, particularly in assessment, remain unclear. This paper presents a multiple-choice test instrument for assessing individuals' knowledge of fundamental…

Previous research reveals that the visual design of open-ended questions should match the response task so that respondents can infer the expected response format. Based on a web survey including specific probes in a list-style open-ended question format, we experimentally tested the effects of varying numbers of answer boxes on several indicators…

Previous research has shown that question characteristics, such as the shape of rating scales, can affect how respondents interpret and respond to questions. For example, earlier studies reported different response distributions for questions employing rating scales in the form of a ladder and in the form of a pyramid. The current experiment,…

One aim of secondary education is to convey informed and multilayered notions, rather than simplistic stereotypes, about other nations. In this context, textbook materials play a decisive role as teaching aids. In this article, we analyze representations of China in seventy-one secondary school textbooks from two federal states in Germany. We used…

Sex and gender bias in anatomy learning materials are considered a "hidden obstacle" to gender equity in medical curricula. The purpose of this study was to investigate whether quantitative sex and gender biases do exist in popular anatomy e-learning platforms and compare the results with those found in contemporary textbooks and…

A core element of teacherss' professional knowledge is their Pedagogical Content Knowledge (PCK). The Refined Consensus Model of PCK defines three realms of PCK: collective PCK, personal PCK and enacted PCK. ePCK encompasses the acts of planning and reflecting on a lesson. Digital simulations allow the training of transferring pPCK to ePCK in…

Analysis of data from single-case intervention studies commonly involves visual analysis. Previous research indicates that visual analysis may suffer from low reliability and unpromising error rates. We investigated the reliability and validity of visual analysis and explored to what extent data trends affect judgments. We administered a…

Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic…
