The impact of research process presentations on secondary school student’s perception of scientific credibility and tentativeness
Supporting students in understanding how scientific knowledge is developed, including its inherent uncertainty, is a key challenge in science education. The research presented here investigated how the formatting of scientific practices and the representation of a scientist’s thought processes influence secondary school student’s perceptions of the scientist’s credibility, the research’s credibility, and the tentativeness of findings. Scientific …
Collaborative knowledge construction with generative AI
Since the beginning of computer-supported collaborative learning (CSCL) research, collaborative writing has been playing a pivotal role as a tool for learning and knowledge construction. In the study presented here, we ask to what extent large language models may not only assist individuals in their writing processes but also serve as a collaboration partner. For this purpose, we analyzed the writing process of individuals supported by ChatGPT. W…
False certainty as an unwanted side effect of knowledge acquisition in computer-based online search and content learning
Collective Knowledge Construction
In this chapter, we present cognitive and sociocultural approaches as two research traditions that represent the individual and the social sides of collective knowledge construction. We discuss theories from sociology, which build a conceptual background for sociocultural considerations and describe the nature of emergent social processes. We also present a model that brings together cognitive, sociocultural, and sociological considerations. Fina…
Emotional Content in Wikipedia Articles on Negative Man-Made and Nature-Made Events
Wikipedia emphasizes the objectivity of content. Yet, Wikipedia articles also deal with negative events that potentially elicit intense emotions. Undesirable outcomes (e.g., earthquakes) are known to elicit sadness, while undesirable outcomes caused by others’ actions (e.g., terrorist attacks) are known to elicit anger. Internet users’ emotional responses are likely to end up in Wikipedia articles on those events as characteristics of Internet us…
The impact of physicians' communication styles on evaluation of physicians and information processing
OBJECTIVE: This study aimed at examining the impact of different types of physicians' communication styles on people's subsequent evaluation of physician attributes as well as on their information processing, attitude and decision making. METHOD: In a between-group experiment, 80 participants watched one of three videos in which a gynaecologist displayed a particular communication style in a consultation situation on contraception with an intraut…

The Effects of Tv and Film Exposure on Knowledge About and Attitudes Toward Mental Disorders
Two empirical studies examined whether the portrayal of mental disorders on television and in films has an effect on people's knowledge about and attitudes toward the mentally ill. Study 1 found that the more often people watched television, the poorer their knowledge was about schizophrenia and obsessive‐compulsive disorder. This finding did not apply to major depression. Study 2 demonstrated that people who watched a documentary film acquired m…
The Impact of Cognitive Anchors on Information-Sharing Behavior
In computer-supported information exchange, people frequently tend to withhold their own information and free-ride on the others' contributions. In doing so, they save costs (time and effort) and maximize their own benefit. However, if everyone behaved in this way, there would be no information sharing at all. In this experiment, we tested if the presentation of a random number could serve as a cognitive anchor and influence the amount of shared …
A systems theoretical approach to online knowledge building
Visualizing Co-Evolution of Individual and Collective Knowledge
This paper describes how processes of knowledge building with wikis may be visualized, citing the user-generated online encyclopedia Wikipedia as an example. The underlying theoretical basis is a framework for collaborative knowledge building with wikis that describes knowledge building as a co-evolution of individual and collective knowledge. These co-evolutionary processes may be visualized graphically, applying methods from social network anal…
Implicit and explicit dialogue structuring in virtual learning groups
Background. The promotion of virtual learning groups by instructional means is gaining importance with the spread of telematic learning. In virtual learning groups, students discuss certain learning materials or cooperate in problem solving by means of computer-mediated communication. Due to the specific features of electronic communication, supportive means appear to be necessary for such learning situations. Aims. The investigation focuses on t…
