Model-Driven Development of Interactive Multimedia Applications

The development of highly interactive multimedia applications is still a challenging and complex task. In addition to the application logic, multimedia applications typically provide a sophisticated user interface with integrated media objects. As a consequence, the development process involves different experts for software design, user interface design, and media design. There is still a lack of concepts for a systematic development which integrates these aspects. This thesis provides a model-driven development approach addressing this problem. Therefore it introduces the Multimedia Modeling Language (MML), a visual modeling language supporting a design phase in multimedia application development. The language is oriented on well-established software engineering concepts, like UML 2, and integrates concepts from the areas of multimedia development and model-based user interface development. MML allows the generation of code skeletons from the models. Thereby, the core idea is to generate code skeletons which can be directly processed in multimedia authoring tools. In this way, the strengths of both are combined: Authoring tools are used to perform the creative development tasks while models are used to design the overall application structure and to enable a well-coordinated development process. This is demonstrated using the professional authoring tool Adobe Flash. MML is supported by modeling and code generation tools which have been used to validate the approach over several years in various student projects and teaching courses. Additional prototypes have been developed to demonstrate, e.g., the ability to generate code for different target platforms. Finally, it is discussed how models can contribute in general to a better integration of well-structured software development and creative visual design

From the Behavior Model of an Animated Visual Language to its Editing Environment Based on Graph Transformation

Animated visual models are a reasonable means for illustrating system behavior. However, implementing animated visual languages and their editing environments is difficult. Therefore, guidelines, specification methods, and tool support are necessary. A flexible approach for specifying model states and behavior is to use graphs and graph transformations. Thereby, a graph can also represent dynamic aspects of a model, like animations, and graph transformations are triggered over time to control the behavior, like starting, modifying, and stopping animations or adding and removing elements. These concepts had already been added to Dia-Meta, a framework for generating editing environments, but they provide only low-level support for specifying and implementing animated visual languages; specifying complex dynamic languages was still a challenging task. This paper proposes the Animation Modeling Language (AML), which allows to model behavior and animations on a higher level of abstraction. AML models are then translated into low-level specifications based on graph transformations. The approach is demonstrated using a traffic simulation

Innovative Learning Environments in STEM Higher Education

As explored in this open access book, higher education in STEM fields is influenced by many factors, including education research, government and school policies, financial considerations, technology limitations, and acceptance of innovations by faculty and students. In 2018, Drs. Ryoo and Winkelmann explored the opportunities, challenges, and future research initiatives of innovative learning environments (ILEs) in higher education STEM disciplines in their pioneering project: eXploring the Future of Innovative Learning Environments (X-FILEs). Workshop participants evaluated four main ILE categories: personalized and adaptive learning, multimodal learning formats, cross/extended reality (XR), and artificial intelligence (AI) and machine learning (ML). This open access book gathers the perspectives expressed during the X-FILEs workshop and its follow-up activities. It is designed to help inform education policy makers, researchers, developers, and practitioners about the adoption and implementation of ILEs in higher education

A study of learner experience design and learning efficacy of mobile microlearning in journalism education

With the increasing number of mobile technologies, people rely on smartphones to connect with the world and obtain news and information. The emergent use of mobile technologies changes the way journalists produce and disseminate news. It is important for journalism educators to know how to support journalists' digital skills development, particularly digital skills of mobile technologies, and understand which new forms of learning are suitable and feasible for those learners in the journalism sector. Previous research has shown that mobile microlearning (MML) can be a promising learning approach for specific learning needs. Mobile microlearning basically means learning no more than five minutes of lessons that are distributed on the smartphone. However, there is only a little evidence on the design and effects of MML in the context of journalism education research. Hence, this dissertation aims to examine whether MML can be a useful approach to facilitate mobile journalists' digital skills learning with smartphones. Adapting a sociotechnical-pedagogical learner experience framework with a usercentered design process, a four-phase formative research cycle was conducted in this dissertation: Phase 1, a systematic literature review of mobile microlearning (Study 1), Phase 2, a needs assessment for an understanding of mobile journalists' learning needs and requirements (Study 2), Phase 3, an iterative design and development of a mobile microcourse and studying its usability and user experience (Study 3), and Phase 4, an examination of the learning efficacy (i.e., effectiveness, efficiency, and appeal) and learner experience of the developed mobile microcourse (Study 4). A mixed-method data collection and analysis approach was applied throughout this dissertation. The results in this research provided evidence-based findings and indicated that MML is a feasible and effective approach to support mobile journalists' just-in-time learning when the MML designs follow four sequential design principles: (a) an aha moment to help with the learners connecting their previous experiences to the importance of current learning topics, (b) interactive content, (c) short exercises, and (d) instant automated feedback. Lastly, the dissertation discussed the results and addressed insights and implications of the MML design to improve learner experience and learning efficacy.Includes bibliographical references

Proceedings of the International Workshop on EuroPLOT Persuasive Technology for Learning, Education and Teaching (IWEPLET 2013)

"This book contains the proceedings of the International Workshop on EuroPLOT Persuasive Technology for Learning, Education and Teaching (IWEPLET) 2013 which was held on 16.-17.September 2013 in Paphos (Cyprus) in conjunction with the EC-TEL conference. The workshop and hence the proceedings are divided in two parts: on Day 1 the EuroPLOT project and its results are introduced, with papers about the specific case studies and their evaluation. On Day 2, peer-reviewed papers are presented which address specific topics and issues going beyond the EuroPLOT scope. This workshop is one of the deliverables (D 2.6) of the EuroPLOT project, which has been funded from November 2010 – October 2013 by the Education, Audiovisual and Culture Executive Agency (EACEA) of the European Commission through the Lifelong Learning Programme (LLL) by grant #511633. The purpose of this project was to develop and evaluate Persuasive Learning Objects and Technologies (PLOTS), based on ideas of BJ Fogg. The purpose of this workshop is to summarize the findings obtained during this project and disseminate them to an interested audience. Furthermore, it shall foster discussions about the future of persuasive technology and design in the context of learning, education and teaching. The international community working in this area of research is relatively small. Nevertheless, we have received a number of high-quality submissions which went through a peer-review process before being selected for presentation and publication. We hope that the information found in this book is useful to the reader and that more interest in this novel approach of persuasive design for teaching/education/learning is stimulated. We are very grateful to the organisers of EC-TEL 2013 for allowing to host IWEPLET 2013 within their organisational facilities which helped us a lot in preparing this event. I am also very grateful to everyone in the EuroPLOT team for collaborating so effectively in these three years towards creating excellent outputs, and for being such a nice group with a very positive spirit also beyond work. And finally I would like to thank the EACEA for providing the financial resources for the EuroPLOT project and for being very helpful when needed. This funding made it possible to organise the IWEPLET workshop without charging a fee from the participants.

Programming Robots for Activities of Everyday Life

Text-based programming remains a challenge to novice programmers in\ua0all programming domains including robotics. The use of robots is gainingconsiderable traction in several domains since robots are capable of assisting\ua0humans in repetitive and hazardous tasks. In the near future, robots willbe used in tasks of everyday life in homes, hotels, airports, museums, etc.\ua0However, robotic missions have been either predefined or programmed usinglow-level APIs, making mission specification task-specific and error-prone.\ua0To harness the full potential of robots, it must be possible to define missionsfor specific applications domains as needed. The specification of missions of\ua0robotic applications should be performed via easy-to-use, accessible ways, and\ua0at the same time, be accurate, and unambiguous. Simplicity and flexibility in\ua0programming such robots are important, since end-users come from diverse\ua0domains, not necessarily with suffcient programming knowledge.The main objective of this licentiate thesis is to empirically understand the\ua0state-of-the-art in languages and tools used for specifying robot missions byend-users. The findings will form the basis for interventions in developing\ua0future languages for end-user robot programming.During the empirical study, DSLs for robot mission specification were\ua0analyzed through published literature, their websites, user manuals, samplemissions and using the languages to specify missions for supported robots.After extracting data from 30 environments, 133 features were identified.\ua0A feature matrix mapping the features to the environments was developedwith a feature model for robotic mission specification DSLs.Our results show that most end-user facing environments exist in the\ua0education domain for teaching novice programmers and STEM subjects. Mostof the visual languages are developed using Blockly and Scratch libraries.\ua0The end-user domain abstraction needs more work since most of the visualenvironments abstract robotic and programming language concepts but not\ua0end-user concepts. In future works, it is important to focus on the development\ua0of reusable libraries for end-user concepts; and further, explore how end-user\ua0facing environments can be adapted for novice programmers to learn\ua0general programming skills and robot programming in low resource settings\ua0in developing countries, like Uganda

Faculty Perceptions of Student Experiences Regarding the Use of MyFoundationsLab

MyFoundationsLab (MFL) was implemented to complement math instruction and increase student performance in developmental/transitional algebra courses. However, student learning outcomes at the college under study demonstrated that some students were still unsuccessful in passing their math course (i.e., Summer 2015:30%, Fall 2015: 27.2%, Spring 2016: 41.6%). The problem addressed in this study explored the learning experiences of students, via a faculty lens, who were unsuccessful in their math course instructionally supported by MFL. Bandura\u27s theory of reciprocal determinism, the technology acceptance model, and the ARCS model of motivational design were used in this qualitative case study to examine the perceptions of 4 faculty regarding student experiences with MFL; faculty were selected through purposeful sampling. The research question explored faculty perceptions of students who failed math while using MFL in addition to the overall learning experiences of students in using the learning system. The major themes that resulted from data analysis through semistructured interviews were student challenges with technology, learning barriers that students experienced, and faculty teaching influences. The emerging project was a faculty professional development seminar emphasizing teaching strategies that supported MFL instruction and faculty in-class teaching. The findings of the study can positively impact social change through affording students positive learning experiences that encourage them to persist in college and ultimately contribute to the economic growth of their communities
