We investigate how facilitators can become triggers and drivers of developing PjBL in a knowledge-based and participatory way for all involved stakeholders in an institutional (learning) setting. The developed and presented instrument which contextualizes value transactions among the networked PjBL stakeholders through empirical PjBL evidence. PjBL success factors and guidelines for effective PjBL frame Value Network Analyses. The demonstrator has been tested in a master course in Business Informatics on Digital Twin generation. Besides the proof of concept, the feasibility of continuous advancements through facilitator participation along individually organized development steps could be demonstrated.

An analysis of social interaction between novice older adults when learning gesture-based skills through simple digital games

The participants were introduced to interactive technology by playing games on touchscreens, playing in pairs with the assistance of a mentor. We focus on two principle aspects, the peer-to-peer interaction during these sessions, and the role of the mentor in progressing the sessions. In the case of peer-to-peer interaction we looked for ways in which players supported each other during interaction to assess the role of peer interaction in this context. In the case of mentoring, we examined the efficacy of a minimalist approach where verbal encouragement, suggestions or (in the last resort) intervention are used to provide support to learners. The sessions showed that learners typically could play and learn basic manipulations independently after initial help and guidance from mentors. We also found that peer interaction, both in verbal and non-verbal communication and cooperative action was broadly a positive influence within sessions, suggesting that there is a significant value in building confidence as well as in learning.

Whom to talk to? A stakeholder perspective on business process development

This paper shows, on the basis of natural language constructs (subject, predicate, object) and communication patterns between actors (subjects), how individual members of an organization could contribute to coherent and intelligible process specifications. A language and tool supporting Subject-oriented Business Process Management (S-BPM) are introduced, allowing organizations to cope with strategic and operational challenges dynamically. As many organizations already work with BPM concepts and technologies, existing approaches to process modelling are also revisited with respect to representing natural language constructs and standard sentence syntax. Since most of them refer either to subjects, predicates, objects or to a respective combination, a roadmap can be developed for enriching existing modelling approaches. In doing so, organizations can benefit from stakeholder inputs for effective business process engineering re-using existing specifications. Keywords Business process modelling Á Subject orientation Á Representation Á Process prototyping Á Business process execution Á Agile business development Á Organization design 1 Introduction Contemporary enterprises have to compete in the business environment by implementing processes and information systems addressing quality, cost, partner/customer relationships and structural flexibility [10]. They need to adapt at the stakeholder level to changing needs albeit increasing their operational efficiency and effectiveness (cf. [6, 18]). In order for flexible operation to be addressed accurately, management and stakeholders have to work on the associated processes [10]. They depend on the particular business objectives set by the enterprise and affect strategic, tactical and operational issues [45]. Business process specifications have to be tailored by participating parties to the specific situation at hand. Of particular importance are the intuitiveness of the notation and coherence of the modelling language. The first addresses the semantic distance to human understanding. It should be minimal, in the sense that it requires minimal cognitive effort to understand and communicate the represented information-organizational design is a good deal negotiating (cf. [22]). When reflecting and redesigning the focus is on business process models and their specification, according to their nature as 'boundary objects' [5]: 'Boundary objects not only help to clarify the attitudes of other communities, they can also make a community's own presuppositions apparent to itself, encouraging reflection, and second loop learning.' As such, processes should be not only intelligible to all stakeholders involved in work procedures, but also to organization and technology developers [1]. Coherence of specification addresses the consistent propagation of strategic objectives, e.g., to establish the enterprise as innovation leader, to tactic and operational structures, e.g., reducing the innovation cycle times within the enterprise

Upcoming CPS will be operated on a unifying basis, the Internet of Behaviors (IoB). It features autonomous while federated CPS architectures and requires corresponding behavior modeling for design and control. CPS design and control involves stakeholders in different roles with different expertise accessing behavior models, termed Digital twins. They mirror the physical CPS part and integrate it with the digital part. Representing role-specific behaviors and provided with automated execution capabilities Digital twins facilitate dynamic adaptation and (re-)configuration. This paper proposes to conceptualize agent-based design for behavior-based Digital twins through subject-oriented models. These models can be executed and, thus, increase the transparency at design and runtime. Patterns recognizing environmental factors and operation details facilitate the configuration of CPS. Subject-oriented runtime support...

Besides explicitness of learning objectives, interactive means of education need to enable intertwining content and communication elements as basic elements of active learning in a flexible way while preserving a certain structure of the learning process. Intelligibility Catchers are a theoretically grounded framework to enable such individualized processes. It allows learners and teachers agreeing and determining a desired learning outcome in written form. This type of e-learning contract enables students to individually explore content and participate in social interactions, while being guided by a transparent learning process structure. The developed implementation empowers learners in terms of creative problem-solving capabilities, and requires adaptation of classroom situations. The framework and its s...

Evidence-based interactive management of change

For this kind of pro-active organizational development support we use an organisational process memory and a communication-based representation technique for role-specific and task-oriented process execution. Both are effective means for organizations becoming agile through interactively modelling the business at the process level and re-constructing or re-arranging process representations according to various needs. The tool allows experiencing role-specific workflows, as the communication-based refinement of work models allows for executable process specifications. When presenting the interactive processes to individuals involved in the business processes, changes can be explored interactively in a context-sensitive way before re-implementing business processes and information systems. The tool is based on a service-oriented architecture and a flexible re...

Game-playing as an effective learning resource for elderly people: encouraging experiential adoption of touchscreen technologies

To include elderly people in ongoing socio-technological developments, we aim to overcome the barriers to learning and adoption such older adults may face. In this contribution, we set the methodological stage for an interactive game-playing approach using touchscreen tablets. By using games in learning settings, we encourage elderly people in digital adoption and skill development. In a first study, a video analysis of game-playing sessions and active learning support were performed. Although approaches that combine game-playing with learning could encourage elderly people to become an integral part of a technologically advancing society, the facilitation of interaction processes in individual and collective gaming seems to be crucial. We report on the performed field study and provide methodological suggestions for investigating digital media adoption.

Representing organizational changes in distributed problem solving environments

IEEE Transactions on Systems, Man, and Cybernetics

The usability of such models mostly depends on their ability to describe communication events occurring in multiagent environments. Hence, a formal communication model is enhanced with adaptation capabilities to capture organizational changes in cooperative problem solving environments. The model meets the appropriate level of abstraction not only for the specification of the communication among a dispersed set of agents, but also for concurrent common, but distributed knowledge, and related (a)synchronous eients. 1. INTRODUCTION Cooperative distributed problem solving is mainly based on communication among agents [2], [4], [SI, [9], [lo], [12], [Ih], [24]. [25], [MI, [46]. In addition, agents do, not only rely on shared and private knowledge (bases) supporting cooperative decision making [7], [ 1 I], [ 191. [26]. [30]. [46]. but also on the organization of work that heavily determines the success of collaborative problem solving [h], [20], [24], [32]. In general, organizational issues concern the "structure of roles together with lines of communication" [8]. Organizational changes comprise modification of roles, agendas, and constraints concerning time, knowledge, etc. It has turned out that group work productivity can only be enhanced if the work context. i.e., knowledge and communication procedures using that knowledge in a decision making process, can be modeled in a Comprehensive way [9]. Thus, organizational modeling has to deal with the following issues: cooperation (tasks, communication, etc.), concurrency. and shared knowledge. Furthermore, it has to cover all Manuscript
