Paper and presentation about the topic of detecting disengaged reading at LAK23

Conference, Conference, Event, Higher Education, Publication, Research topic, Self-Regulation, Target group

At the recent Learning Analytics and Knowledge Conference (LAK23), Daniel Biedermann presented his paper "Detecting the Disengaged Reader - Using Scrolling Data to Predict Disengagement during Reading," to shed light on the potential for early detection of disengagement in readers. The paper presents a unique method for early disengagement detection that relies solely on the classification of scrolling data. By transforming scrolling data into a time series representation, each point of the series represents the vertical position of the viewport in the text document. Time series classification algorithms are then used to evaluate the data.The results were promising, with the method able to classify disengagement early with up to 70% accuracy. However, the study also observed differences in performance depending on which texts were included in the training dataset. Biedermann…

New Pub: Superpowers in the Classroom: Hyperchalk is an Online Whiteboard for Learning Analytics Data Collection

Computer-supported collaborative learning, Conference, Conference, Event, Further Education, General education, Higher Education, Learning Analytics, Lifelong Learning, Publication, School, Technical paper

A new system demonstration paper authored by Lukas Menzel, Sebastian Gombert, Daniele Di Mitri and Henrik Drachsler has been released as part of the ECTEL 2022 proceedings. In this paper, we present Hyperchalk, a self-hosted collaborative online whiteboard software. Similar to commercial solutions like Miro or Flinga, this software provides users with collaborative boards which they can use to draw, write or sketch together. However, unlike commercial solutions, Hyperchalk allows for collecting rich log data, which can be used to study the behaviour of its users and to allow Learning Analytics and studies on computer-supported collaborative learning. Moreover, Hyperchalk comes with a built-in replay mode which allows watching how users behave in its spaces. It supports the LTI1.3 standard, which enables seamless integration with learning management systems such as Moodle,…

New Pub: Personality and Social Presence

Higher Education, Journal, Publication

Social presence is an important and well-established construct in learning scenarios that make use of online-based technology to mediate learning activities and communication among students, like online learning and distance education. Researchers and practitioners refer to social presence to better understand the socio-emotional dimension of these learning scenarios and/or improve the quality of the experience. As a construct that has emerged out of a socio-psychological research tradition, social presence has mostly been understood as a state variable, the result of situative/contextual factors, like the communication media, group size, or instructional design. What has been entirely overlooked is the possibility that some students are inherently more prone to experiencing social presence, while others may be less inclined to these perceptions. This study published in Open Education Studies, authored by Joshua Weidlich,…

New Pub: Social Presence: Conceptualization and Measurement

Empirical Study, Journal, Literature review, Publication

Social presence is an important and well-established construct for learning scenarios that make use of online-based technology to mediate learning activities and communication among students. Researchers and practitioners refer to social presence to better understand the socio-emotional dimension of these learning scenarios and/or improve the quality of the experience. However, many researchers in the past have pointed to the shaky foundation that is the conceptualization and measurement of social presence. In other words, there is no agreement on what social presence actually *is* and, consequently, how it should be measured. This makes it difficult to cumulatively build on prior research, possibly explaining the conflicting findings and the rather slow progress this field of research has been making. Our publication in Educational Psychology Review, authored by Karel Kreijns, Kate Xu, and…

New Pub: Digital self-control interventions for distracting media multitasking – A systematic review

General education, Journal, Open access, Publication

Digital distractions can interfere with goal attainment and lead to undesirable habits that are hard to get red rid of. Various digital self-control interventions promise support to alleviate the negative impact of digital distractions. These interventions use different approaches, such as the blocking of apps and websites, goal setting, or visualizations of device usage statistics. While many apps and browser extensions make use of these features, little is known about their effectiveness. This systematic review synthesizes the current research to provide insights into the effectiveness of the different kinds of interventions. The interventions showed varying degrees of effectiveness, and especially interventions that relied purely on increasing the participants' awareness were barely effective. For those interventions that sanctioned the use of distractions, the current literature indicates that the sanctions have to…
