    Generation of Multiple True False Questions
    (20. Fachtagung Bildungstechnologien (DELFI), 2022) Kasakowskij,Regina; Kasakowskij, Thomas; Seidel, Niels
    Assessments are an important part of the learning cycle and enable the development and promotion of competencies. However, the manual creation of assessments is very time-consuming. Therefore, the number of tasks in learning systems is often relatively small. In this paper, we present an algorithm that can automatically generate an arbitrary number of German True False statements from a textbook using the GPT-2 model. The algorithm was evaluated with a selection of textbook chapters from four different academic disciplines and rated by domain experts. One-third of the generated MTF Questions are suitable for learning. The algorithm provides instructors with an easier way to create assessments on chapters of textbooks to test factual knowledge.

    Impacts of Disruption on Secondary Task Knowledge: Recovery Modes and Social Nuances
    (Mensch und Computer 2019 - Tagungsband, 2019) Oemig, Christoph; Gross, Tom
    The working memory of the human brain has always had a strong influence on the design of Human-Computer Interaction. Yet, it is limited in capacity and loses its contents over time. Research regarding these constraints typically focused on single user tasks and systems. Collaborative settings and systems introduce the need for the secondary task of coordination which shares the same conditions and constraints as the knowledge of the primary task. Additionally, it is easily compromised by interruption and interference. Our approach seeks to understand the impacts of disruption on secondary task knowledge, but from a different angle than previous related work. Since it is hard to avoid disruption entirely, it aims to understand how users recover from disruptions in order to help them recover the best way possible from different types of interruptions using appropriate mechanisms and cues. This paper reports on the results of one of the first experiments along the way, observing the effects of four types of interruptions revealing different modes of recovery and social nuances that inform the design of adaptive coordination support systems.

    Interaction of reading and assessment behavior
    (20. Fachtagung Bildungstechnologien (DELFI), 2022) Menze, Dennis; Seidel, Niels; Kasakowskij, Regina
    Reading and assessment are elementary activities for knowledge acquisition in online learning. Assessments represented as quizzes can help learners to identify gaps in their knowledge and understanding, which they can then overcome by reading the corresponding text-based course material. Reversely, quizzes can be used to evaluate reading comprehension. In this paper, we examine the interactions between reading and quiz activities using scroll and log data from an online undergraduate course (N=142). By analyzing processes and sequential patterns in user sessions, we identified six session clusters for characteristic reading and quiz patterns potentially relevant for adaptive learning support. Using these session clusters, we further clustered students by their reading and quiz behavior over six time periods within the semester. The results hypothesize a personalization for seven groups of learners characterized by their temporal activity and predominant quiz and reading behavior.

    UX at the Right Level - Appropriately Plan the UX Expertise Using the PUXMM – A UX Maturity Model for Projects
    (i-com: Vol. 20, No. 1, 2021) Gilbert, David; Fischer, Holger; Röder, Dirk
    Usability and user experience maturity models are used to evaluate the capabilities of an organization in order to provide an assessment of their ability to develop usable products. But, as the main focus of such models is on an all-encompassing organizational level, they are difficult to implement in more complex organizations with a wide range of diverse and interlinked projects. This paper presents a project related UX maturity model, which was developed at DB Systel to address this issue: the PUXMM. It takes into account the nested internal customer relationships between departments and subcontractors and applies a human-centered design approach. There are two practical application scenarios for the PUXMM. It can be used to determine the UX maturity level of an ongoing project and as checklist to align a project to a desired maturity level from the outset.

    Validation of a German Version of the Collision Anxiety Questionnaire
    (Proceedings of Mensch und Computer 2024, 2024) Ring, Patrizia; Tietenberg, Julius; Masuch, Maic
    The main quality of virtual reality (VR) is its high immersive potential. However, the resulting inability to perceive the real world surroundings can distract users from the application due to the fear of colliding with obstacles or other people. The Collision Anxiety Questionnaire (CAQ) by Ring et al. measures this fear of colliding and consists of ten items in three subscales: general collision anxiety, orientation, and interpersonal collision anxiety. In this paper, we present a validated German version of the CAQ, which showed a good model fit, including good reliability and internal and discriminant validity. By validating the questionnaire, we offer researchers a tool to further explore and evaluate the concept of collision anxiety, helping to uncover previously under-explored aspects of the user experience.
