Unleashing the Potential of Conversational Agents for Course Evaluations: Empirical Insights from a Comparison with Web Surveys
(Association for Information Systems, 2020)
Recent advances in Natural Language Processing (NLP) bear the opportunity to design new forms of human-computer interaction with conversational interfaces. However, little is known about how these interfaces change the way users respond in online course evaluations. We aim to explore the effects of conversational agents (CAs) on the response quality of online course evaluations in education compared to the common standard of web surveys. Past research indicates that web surveys come with disadvantages, such as poor ...

SPAM – A Process Model for Developing Smart Personal Assistants
(ScholarSpace, 2020)
Information technology capabilities are growing at an impressive pace and increasingly overstrain the cognitive abilities of users. User assistance systems such as online manuals try to help the user in handling these systems. However, there is strong evidence that traditional user assistance systems are not as effective as intended. With the rise of smart personal assistants, such as Amazon’s Alexa, user assistance systems are becoming more sophisticated by offering a higher degree of interaction and intelligence. ...

Alexa, Can You Help Us Solve This Problem? How Conversations With Smart Personal Assistant Tutors Increase Task Group Outcomes
(Association for Computing Machinery, 2019)
Despite a growing body of research about the design and use of Smart Personal Assistants, existing work has mainly focused on their use as task support for individual users in rather simple problem scenarios. Less is known about their ability to improve collaboration among multiple users in more complex problem settings. In our study, we directly compare 21 groups who either use a Smart Personal Assistant tutor or a human tutor when solving a problem task. The results indicate that groups interacting with Smart ...

Process is King: Evaluating the Performance of Technology-mediated Learning in Vocational Software Training
(2018-09-01)
Technology-mediated learning (TML) is a major trend in education, since it allows to integrate the strengths of traditional- and IT-based learning activities. However, TML providers still struggle in identifying areas for improvement in their TML offerings. One reason for their struggles is inconsistencies in the literature regarding drivers of TML performance. Prior research suggests that these inconsistencies in TML literature might stem from neglecting the importance of considering the process perspective in ...

Machines as teammates: A research agenda on AI in team collaboration
(2019-07-06)
What if artificial intelligence (AI) machines became teammates rather than tools? This paper reports on an international initiative by 65 collaboration scientists to develop a research agenda for exploring the potential risks and benefits of machines as teammates (MaT). They generated 819 research questions. A subteam of 12 converged them to a research agenda comprising three design areas – Machine artifact, Collaboration, and Institution – and 17 dualities – significant effects with the potential for benefit or harm. ...

Towards a Technique for Modeling New Forms of Collaborative Work Practices – The Facilitation Process Model 2.0
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2020)
Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by practitioners themselves without the ongoing support of external collaboration professionals. A key design activity in CE concerns modeling current and future collaborative work practices. CE researchers and practitioners have used the Facilitation Process Model (FPM) technique. However, this modeling technique suffers from a number of shortcomings to model contemporary ...

Insights into Using IT-Based Peer Feedback to Practice the Students Providing Feedback Skill
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2019)
The skills students need nowadays have changed over the last decades. The required skills are shifting more and more towards higher order thinking skills, such as critical thinking, collaboration and communication. One of the main ways of practicing these skills is through formative feedback, which consists of self-assessment and peer-assessment in our setting.
However, today’s lecturers are facing the challenge that the number of students per lecture is continuously increasing, while the available budget is stagnating. ...

Der „elektronische Personalausweis“ in Deutschland: Gesetzgebungsverfahren, Einflussfaktoren und Pfade
(2010-08-27)
Zum 1. November 2010 wird in Deutschland der neue Personalausweis starten, der gegenüber dem bisherigen Dokument drei neue Funktionen enthält: Die Speicherung biometrischer Daten, die optionale Signaturfunktion und den elektronischen Identitätsnachweis, also eine technische Funktion zur elektronischen Authentisierung. Die Rechtsgrundlagen wurden mit der Verabschiedung des neuen Gesetzes über Personalausweise und den elektronischen Identitätsnachweis sowie zur Änderung weiterer Vorschriften am 18. Dezember 2008 im ...

Trust
(2016-10)
Trust is the enabler of social interaction. Although the origins of research on trust traditionally lie outside the Information Systems (IS) domain, the importance of trust for IS research rapidly grew in the late 1990s, and it is still growing with the increasing ubiquity and advancement of technology in organizations, virtual teams, online markets, and user-technology interactions. Theoretically, the central role of trust is tied to the growing social change that Information and Communication Technology (ICT) has ...

Unlocking Transfer Learning in Argumentation Mining: A Domain-Independent Modelling Approach
(GITO Verlag, 2020)
Argument identification is the fundamental block of every Argumentation Mining pipeline, which in turn is a young upcoming field with multiple applications ranging from strategy support to opinion mining and news fact-checking. We developed a model, which is tackling the two biggest practical and academic challenges of the research field today. First, it addresses the lack of corpus-agnostic models and, second, it tackles the problem of human-labor-intensive NLP models being costly to develop. We do that by suggesting ...
