    Impact of learners’ video interactions on learning success and cognitive load
    (International Society of the Learning Sciences, 2021) Ruf, Alessia; Leisner, David; Zahn, Carmen; Opwis, Klaus; Hmelo-Silver, Cindy; de Wever, Bram; Oshima, Jun [in: 14th International Conference on Computer-Supported Collaborative Learning – CSCL 2021]
    Enhanced video-based learning environments provide new tools (e.g., hyperlinks) – along with the well-known basic video control tools (e.g., play, pause, rewind) – that afford learners‘ enhanced interaction with videos. With these tools, learners can actively transform existing videos into their own hypervideo structures by adding hyperlinks and own materials. Unlike research on basic control tools that has revealed positive impacts on learning, research on enhanced tools is still rare and conflicting. It is thus open, whether the tools support generative interested learning or put too much extrinsic cognitive load onto learners. In the present study, we investigated the effects of video annotation and hyperlinking tools on learning success and cognitive load by analyzing tool-related interaction behavior data of 141 university students. Results indicated that the frequent use of enhanced video tools positively predicted learning success and a decrease in cognitive load. Implications of these results are discussed.

    Logible: Detecting, Analyzing and Visualizing Behavior Sequences for Investigating Learning Behavior
    (International Society of the Learning Sciences, 2021) Ruf, Alessia; Jäger, Joscha; Niederhauser, Mario; Zahn, Carmen; Opwis, Klaus; Wichmann, Astrid; Hoppe, H. Ulrich; Rummel, Nikol [in: General Proceedings of the 1st Annual Meeting of the International Society of the Learning Sciences 2021]
    Logible is a highly sensitive web-based interactive tool that automatically detects behavior sequences from raw log files. It further analyzes and visualizes sequences and allows for comparisons of behavior data between different experimental conditions without the use of other software. Logible was developed based on an iterative, exploratory, and rule-based method devised to find meaningful sequences from 92 data sets of students who learned individually or collaboratively with an enhanced video-based environment. The tool is customizable and thus enables researchers to investigate learning behavior with various kinds of sequentially logged interaction data (from web-based video environments, online learning platforms etc.).

    Introducing a new approach for investigating learning behavior
    (International Society of the Learning Sciences, 2021) Ruf, Alessia; Niederhauser, Mario; Jäger, Joscha; Zahn, Carmen; Opwis, Klaus; Hmelo-Silver, Cindy; de Wever, Bram; Oshima, Jun [in: 14th International Conference on Computer-Supported Collaborative Learning – CSCL 2021]
    The potential of learners’ video interactions to understand learning behavior has been recognized in previous research. However, little research has yet been conducted on enhanced video-based environments using behavior sequence analyses. Hence, we developed Logible, a sensitive, web-based tool to detect and analyze meaningful behavior sequences of learners interacting with such environments. The tool is based on an iterative method. With Logible we were able to visualize learning behavior and emphasize differences in experimental conditions.
