Conference paper (peer-reviewed)abstract
- How might the content and outcomes of tertiary education programmes be described and analysed in order to understand how they are structured and function? To address this question we develop a framework for modelling graduate competencies linked to tertiary degree programmes in the computing disciplines. While the focus of our work is computing the framework is applicable to education more broadly. The work presented here draws upon the pioneering curricular document for information technology (IT2017), curricular competency frameworks, other related documents such as the software engineering competency model (SWECOM), the Skills Framework for the Information Age (SFIA), current research in competency models, and elicitation workshop results from recent computing conferences. The aim is to inform the ongoing Computing Curricula (CC2020) project, an endeavour supported by the Association for Computing Machinery (ACM) and the IEEE Computer Society. We develop the Competency Learning Framework (CoLeaF), providing an internationally relevant tool for describing competencies. We argue that this competency based approach is well suited for constructing learning environments and assists degree programme architects in dealing with the challenge of developing, describing and including competencies relevant to computer and IT professionals. In this paper we demonstrate how the CoLeaF competency framework can be applied in practice, and though a series of case studies demonstrate its effectiveness and analytical power as a tool for describing and comparing degree programmes in the international higher education landscape.

Towards a visual compositional relational programming methodology
- 2012
-
In: Diagrams 2012. ; , s. 17-19
-
Conference paper (peer-reviewed)abstract
- We present a new visual programming method, based on Combilog, a compositional relational programming language. In this paper we focus on the compositional aspect of Combilog, the make operator, visually implementing it via a modification of Higraph diagrams, in an attempt to overcome the obscurity and complexity in the textual representation of this operator.

New technologies in the education of native language
- 2004
-
In: Greek language education in Scandinavia. ; , s. 73-76
-
Conference paper (peer-reviewed)abstract
- Education in mother tongue as well as any education, demands the use of adequate methods and tools to be effective. New technology offers many possibilities for this purpose. In the present paper different IT solutions are discussed and their contribution to the goal of learning the mother tongue are examined. Necessary conditions for successful learning are supposed to be the careful choice and the continuous adaptation of used IT tools to the psychological learning process of the child.

Load-Balanced Data Collection through Opportunistic Routing
- 2015. - 9
-
In: 2015 International Conference on Distributed Computing in Sensor Systems. - 9781479988563 ; , s. 62-70
-
Conference paper (peer-reviewed)abstract
- Wireless Sensor Networks performing low-power data collection often suffer from uneven load distribution among nodes. Nodes close to the network root typically face a higher load, see their battery deplete first, and become prematurely unable to operate (both sensing and relaying other nodes' data). We argue that opportunistic routing, by making forwarding decision on a per-packet basis and at the receiver rather than the sender, has the potential to better balance the load across nodes. We extend ORPL, an opportunistic version of the standard routing protocol RPL, with support for load-balancing. In our protocol, ORPL-LB, nodes continuously adapt their wake-up interval in order to adjust their availability and attain a deployment-specific target duty cycle. We implement our protocol in Contikiand present our experimental validation in Indriya, a 93-nodestestbed. Our results show that ORPL-LB reduces significantly(by approximately 40%) the worst node's duty cycle, with little or no impact on packet delivery ratio and latency.

Uncertainty Detection as Approximate Max-Margin Sequence Labelling
- 2010
-
In: CoNLL 2010. - : Association for Computational Linguistics. ; , s. 84-91
-
Conference paper (peer-reviewed)abstract
- This paper reports experiments for the CoNLL 2010 shared task on learning to detect hedges and their scope in natural language text. We have addressed the experimental tasks as supervised linear maximum margin prediction problems. For sentence level hedge detection in the biological domain we use an L1-regularised binary support vector machine, while for sentence level weasel detection in the Wikipedia domain, we use an L2-regularised approach. We model the in-sentence uncertainty cue and scope detection task as an L2-regularised approximate maximum margin sequence labelling problem, using the BIO-encoding. In addition to surface level features, we use a variety of linguistic features based on a functional dependency analysis. A greedy forward selection strategy is used in exploring the large set of potential features. Our official results for Task 1 for the biological domain are 85.2 F1-score, for the Wikipedia set 55.4 F1-score. For Task 2, our official results are 2.1 for the entire task with a score of 62.5 for cue detection. After resolving errors and final bugs, our final results are for Task 1, biological: 86.0, Wikipedia: 58.2; Task 2, scopes: 39.6 and cues: 78.5.

Challenges and recommendations for the design and conduct of global software engineering courses : A systematic review
- 2016
-
In: Proceedings of The 2015 Iticse Conference on Working Group Reports (Iticse-Wgp'15). - New York : ACM Press. - 9781450341462 ; , s. 1-39
-
Conference paper (peer-reviewed)abstract
- Context: Global Software Engineering (GSE) has become the predominant form of software development for global companies and has given rise to a demand for students trained in GSE. In response, universities are developing courses and curricula around GSE and researchers have begun to disseminate studies of these new approaches.Problem: GSE differs from most other computer science fields, however, in that practice is inseparable from theory. As a result, educators looking to create GSE courses face a daunting task: integrating global practice into the local classroom.Aim: This study aims to ameliorate the very difficult task of teaching GSE by delineating the challenges and providing some recommendations for overcoming them.Method: To meet our aims we pose two research questions ("When teaching GSE to students in Higher Education, what are the (a) challenges, and (b) recommendations for addressing them") and then conduct a systematic literature review (SLR) to determine the answers to these questions. Our SLR follows a carefully designed and validated protocol.Results: We found 82 papers that addressed our research questions. Our findings indicate that in addition to the challenges posed by GSE in general, particular problems arise in educational situations. The majority of these challenges fall into the "global distance" category, though teamwork challenges and people issues (such as trust) also commonly arise. Organizational differences between institutions, differing skill sets between students in different locations, and varying cultural work norms, for example, all operate within educational settings in quite different ways than in professional development teams. Integrating cultural training, conducting teamwork exercises to build trust, and instructor monitoring of team communication are all examples of techniques that have been used successfully by educators according to our review.Conclusion: Despite the severity of the challenges in GSE education, many institutions have successfully developed courses and curricula targeting GSE. Indeed, for each of the challenges we have identified in the literature there are numerous recommendations for overcoming them. Instructors can use the recommendations given in this study as a starting point to running successful GSE courses.

Information Technology as a tool for democratic skills
- 2007
-
In: Forms of democracy in education. - 9789607860750 ; , s. 155-162
-
Conference paper (peer-reviewed)abstract
- Democracy does not depend only on political conditions and processes in society. Psychological conditions and processes of participating persons or citizens are also important. Dialog, for example, is necessary for democracy. But dialog does not occur among people who are absolutely convinced about the truth of their ideas. A personal critical attitude toward own beliefs is a necessary precondition for dialog and democracy. How can IT train for self-criticism, systematic searching and critical thinking? This paper presents two IT-tools, a micro-world simulation of society and a decision support system, which can be used to stimulate autonomous thinking. Autonomous thinking is unconstraint, self-critical, systematic and holistic problem solving and decision making. Both these tools can be used in distance education for democracy using the Internet.

Can micro world simulations assess and stimulate ethical competence?
- 2008
-
In: Proceedings of the Tenth International Conference ETHICOMP 2008. - Mantua, Italy : University of Pavia. - 9788890286995 ; , s. 503-510
-
Conference paper (peer-reviewed)abstract
- Micro worlds can be constructed to assess and promote the ethical competence of users. However, the theoretical basis has to be on psychological problem solving and decision making processes. In this paper we discuss the conditions necessary for a micro world as a method to measure and train ethical competence. Two things in particular are interesting to investigate: 1) To determine which parameters to measure, that indicate autonomous decision making, and 2) to establish a model for interpreting the proceedings and the subject’s interaction with the simulation as a representation of the psychological problem solving and decision making process.

Introducing Programming and Digital Competence in Swedish K-9 Education
- 2017
-
In: Informatics in Schools. - Cham : Springer. - 1611-3349 .- 0302-9743. - 9783319714820 - 9783319714837 ; , s. 117-128
-
Conference paper (peer-reviewed)abstract
- The role of computer science and IT in Swedish schools has varied throughout the years. In fall 2014, the Swedish government gave the National Agency for Education (Skolverket) the task of preparing a proposal for K–9 education on how to better address the competences required in a digitalized society. In June 2016, Skolverket handed over a proposal introducing digital competence and programming as interdisciplinary traits, also providing explicit formulations in subjects such as mathematics (programming, algorithms and problem-solving), technology (controlling physical artifacts) and social sciences (fostering aware and critical citizens in a digital society). In March 2017, the government approved the new curriculum, which needs to be implemented by fall 2018 at the latest. We present the new K–9 curriculum and put it in a historical context. We also describe and analyze the process of developing the revised curriculum, and discuss some initiatives for how to implement the changes.
