However, the availability of university-wide services in the mobile sector is still poor. If they exist they usually result from individual activities of students and teachers. Mobile applications can have an essential impact on the improvement of students’ self-organization as well as on the design and enhancement of specific learning scenarios, though. This article introduces a mobile campus app framework, which integrates central campus services and decentralized learning applications. An analysis of strengths and weaknesses of different approaches is presented to summarize and evaluate them in terms of requirements, development, maintenance and operation. The article discusses the underlying service-oriented architecture that allows transferring the campus app to other universities or institutions at reasonable cost. It concludes with a presentation of the results as well as ongoing discussions and future work KW - Mobile Campus Application KW - Hybrid App KW - Framework KW - Service-oriented Architecture Y1 - 2015 UR - http://www.degruyter.com/view/j/icom.2015.14.issue-1/icom-2015-0016/icom-2015-0016.xml U6 - https://doi.org/10.1515/icom-2015-0016 SN - 2196-6826 VL - 2015 IS - 14 SP - 63 EP - 73 PB - de Gruyter CY - Berlin ER - TY - JOUR A1 - Liang, Feng A1 - Liu, Yunzhen A1 - Liu, Hai A1 - Ma, Shilong A1 - Schnor, Bettina T1 - A Parallel Job Execution Time Estimation Approach Based on User Submission Patterns within Computational Grids JF - International journal of parallel programming N2 - Scheduling performance in computational grid can potentially benefit a lot from accurate execution time estimation for parallel jobs. Most existing approaches for the parallel job execution time estimation, however, require ample past job traces and the explicit correlations between the job execution time and the outer layout parameters such as the consumed processor numbers, the user-estimated execution time and the job ID, which are hard to obtain or reveal. This paper presents and evaluates a novel execution time estimation approach for parallel jobs, the user-behavior clustering for execution time estimation, which can give more accurate execution time estimation for parallel jobs through exploring the job similarity and revealing the user submission patterns. Experiment results show that compared to the state-of-art algorithms, our approach can improve the accuracy of the job execution time estimation up to 5.6 %, meanwhile the time that our approach spends on calculation can be reduced up to 3.8 %.

The ordered multiple interpretation of a word is obtained by concatenating the images of that word in the given order of morphisms. The arbitrary multiple interpretation of a word is the semigroup generated by the images of that word. These interpretations are naturally extended to languages. Four types of ambiguity of multiple interpretation schemata on a language are defined: o-ambiguity, internal ambiguity, weakly external ambiguity and strongly external ambiguity. We investigate the problem of deciding whether a multiple interpretation scheme is ambiguous on regular languages.

T1 - An automatically configured algorithm selector JF - The journal of artificial intelligence research N2 - Algorithm selection (AS) techniques - which involve choosing from a set of algorithms the one expected to solve a given problem instance most efficiently - have substantially improved the state of the art in solving many prominent AI problems, such as SAT, CSP, ASP, MAXSAT and QBF. Although several AS procedures have been introduced, not too surprisingly, none of them dominates all others across all AS scenarios. Furthermore, these procedures have parameters whose optimal values vary across AS scenarios. This holds specifically for the machine learning techniques that form the core of current AS procedures, and for their hyperparameters. Therefore, to successfully apply AS to new problems, algorithms and benchmark sets, two questions need to be answered: (i) how to select an AS approach and (ii) how to set its parameters effectively. We address both of these problems simultaneously by using automated algorithm configuration. Specifically, we demonstrate that we can automatically configure claspfolio 2, which implements a large variety of different AS approaches and their respective parameters in a single, highly-parameterized algorithm framework. Our approach, dubbed AutoFolio, allows researchers and practitioners across a broad range of applications to exploit the combined power of many different AS methods. We demonstrate AutoFolio can significantly improve the performance of claspfolio 2 on 8 out of the 13 scenarios from the Algorithm Selection Library, leads to new state-of-the-art algorithm selectors for 7 of these scenarios, and matches state-of-the-art performance (statistically) on all other scenarios. Compared to the best single algorithm for each AS scenario, AutoFolio achieves average speedup factors between 1.3 and 15.4.

T1 - aspeed: Solver scheduling via answer set programming JF - Theory and practice of logic programming N2 - Although Boolean Constraint Technology has made tremendous progress over the last decade, the efficacy of state-of-the-art solvers is known to vary considerably across different types of problem instances, and is known to depend strongly on algorithm parameters. This problem was addressed by means of a simple, yet effective approach using handmade, uniform, and unordered schedules of multiple solvers in ppfolio, which showed very impressive performance in the 2011 Satisfiability Testing (SAT) Competition. Inspired by this, we take advantage of the modeling and solving capacities of Answer Set Programming (ASP) to automatically determine more refined, that is, nonuniform and ordered solver schedules from the existing benchmarking data. We begin by formulating the determination of such schedules as multi-criteria optimization problems and provide corresponding ASP encodings. The resulting encodings are easily customizable for different settings, and the computation of optimum schedules can mostly be done in the blink of an eye, even when dealing with large runtime data sets stemming from many solvers on hundreds to thousands of instances. Also, the fact that our approach can be customized easily enabled us to swiftly adapt it to generate parallel schedules for multi-processor machines.

In particular, many Al problems such as reasoning in a nonmonotonic setting can be directly formulated in ASP. Although the main problems of ASP are of high computational complexity, complete for the second level of the Polynomial Hierarchy, several restrictions of ASP have been identified in the literature, under which ASP problems become tractable. In this paper we use the concept of backdoors to identify new restrictions that make ASP problems tractable. Small backdoors are sets of atoms that represent "clever reasoning shortcuts" through the search space and represent a hidden structure in the problem input. The concept of backdoors is widely used in theoretical investigations in the areas of propositional satisfiability and constraint satisfaction. We show that it can be fruitfully adapted to ASP. We demonstrate how backdoors can serve as a unifying framework that accommodates several tractable restrictions of ASP known from the literature. Furthermore, we show how backdoors allow us to deploy recent algorithmic results from parameterized complexity theory to the domain of answer set programming. (C) 2015 Elsevier B.V.

Informatics has contributed to the scientific and technological development of our society in general and to the digital revolution in particular. Computational thinking is the term indicating the key ideas of this discipline that might be included in the key competencies underlying the curriculum of compulsory education. The educational potential of informatics has a history dating back to the sixties. In this article, we briefly revisit this history looking for lessons learned. In particular, we focus on experiences of teaching and learning programming. However, computational thinking is more than coding. It is a way of thinking and practicing interactive dynamic modeling with computers. We advocate that learners can practice computational thinking in playful contexts where they can develop personal projects, for example building videogames and/or robots, share and discuss their construction with others. In our view, this approach allows an integration of computational thinking in the K-12 curriculum across disciplines.

More importantly, they are invited to contribute actively on this issue in form of short case studies of their countries. Until now, very few countries have been successful in implementing Informatics or Computing at primary and lower secondary level. The spectrum from digital literacy to informatics, particularly as a discipline in its own right, has not really achieved a breakthrough and seems to be underrepresented for these age groups. The goal of this workshop is not only to discuss the anamnesis and diagnosis of this fragmented field, but also to discuss and suggest viable forms of therapy in form of setting educational standards. Making visible good practices in some countries and comparing successful approaches are rewarding tasks for this workshop. Discussing and defining common educational standards on a transcontinental level for the age group of 14 to 15 years old students in a readable, assessable and acceptable form should keep the participants of this workshop active beyond the limited time at the workshop.

This was done in the second part of the pilot study whose aim was to provide equity to control group teachers and students by exposing them to the ABRACADABRA treatment after the end of phase 1. This opportunity was used to follow the phase 1 teachers to see how the skills learned were being transformed into results. A standard three-day initial training and planning session on how to use ABRA to teach literacy was held at the beginning of each phase for ABRA teachers (phase 1 experimental and phase 2 delayed ABRA). Teachers were provided with teaching materials including a tentative ABRA curriculum developed to align with the Kenyan English Language requirements for year 1 and 3 students. Results showed that although there was no significant difference between the groups in vocabulary-related subscales which include word reading and meaning as well as sentence comprehension, students in ABRACADABRA classes improved their scores at a significantly higher rate than students in control classes in comprehension related scores. An average student in the ABRACADABRA group improved by 12 and 16 percentile points respectively compared to their counterparts in the control group.

In this paper, we promote the implementation and usage of a collaborative educational video annotation functionality to overcome these two challenges. Different use cases and requirements, as well as details of the implementation, are explained. Furthermore, we suggest more improvements to foster a culture of participation and an algorithm for the extraction of semantic data. Finally, evaluations in the form of user tests and questionnaires in a MOOC setting are presented. The results of the evaluation are promising, as they indicate not only that students perceive it as useful, but also that the learning effectiveness increases. The combination of personal lecture video annotations with a semantic topic map was also evaluated positively and will thus be investigated further, as will the implementation in a MOOC context.

A sample of 117 children aged 6:6-9:0 years were randomly assigned into three experimental groups of DA conditions: 3D, 2D, and NC, and one control group (C). All groups received the pre- and post-teaching Analogies subtest of the Cognitive Modifiability Battery (CMB-AN). The experimental groups received a teaching phase in conditions similar to the pre-and post-teaching phases. The findings showed that cognitive modifiability, in a 3D IVR, was distinctively higher than in the two other experimental groups (2D computer group and NC group). It was also found that the 3D group showed significantly higher performance in transfer problems than the 2D and NC groups.

Competitions play an important role for learners as a source of inspiration, innovation, and attraction. Running contests in informatics for school students for many years, we have noticed that the students consider the contest experience very engaging and exciting as well as a learning experience. A contest is an excellent instrument to involve students in problem solving activities. An overview of infrastructure and development of an informatics contest from international level to the national one (the Bebras contest on informatics and computer fluency, originated in Lithuania) is presented. The performance of Bebras contests in 23 countries during the last 10 years showed an unexpected and unusually high acceptance by school students and teachers. Many thousands of students participated and got a valuable input in addition to their regular informatics lectures at school. In the paper, the main attention is paid to the developed tasks and analysis of students’ task solving results in Lithuania.

BT - Adaptierbare Gamification in einer Anfänger-Programmiervorlesung JF - HDI 2014 : Gestalten von Übergängen N2 - Durch den Einsatz von Spielen und Spielelementen in Lernkontexten wird versucht, Lernende zur Beschäftigung mit den Lerninhalten zu motivieren. Spielerische Elemente haben allerdings nicht nur positive motivationale Effekte: Sie können sich beispielsweise negativ auf die intrinsische Motivation auswirken, und auch nicht jeder Lernende spielt gerne. Um negativen Einflüssen von Gamification entgegenzuwirken, wurde ein Toolkit für adaptierbare Lernumgebungen entwickelt. Damit erzeugte Lernumgebungen erlauben es Studierenden, den Grad der Gamification selbst zu bestimmen, indem Spielelemente an- und abgeschaltet werden. Im Rahmen einer Anfängerprogrammiervorlesung wurden Lernspielaufgaben aus den existierenden, optionalen interaktiven eTests entwickelt und Studierenden als zusätzliche Lerngelegenheit angeboten. Eine erste explorative Studie bestätigt die Vermutung, dass die Akzeptanz des adaptierbaren Lernspiels sehr hoch ist, es aber dennoch Studierende gibt, welche die Lernumgebung ohne Spielelemente durcharbeiten. Somit bietet adaptierbare Gamification verschiedenen Studierenden die Möglichkeit, sich zusätzliche motivationale Anreize durch Zuschalten von Spielelementen zu verschaffen, ohne dabei zum Spielen „genötigt“ zu werden.

In response to these needs key competencies in understanding, developing and using new digital technologies are being brought into focus in school and university programmes. The IFIP TC3 conference "KEYCIT – Key Competences in Informatics and ICT (KEYCIT 2014)" was held at the University of Potsdam in Germany from July 1st to 4th, 2014 and addressed the combination of key competencies, Informatics and ICT in detail. The conference was organized into strands focusing on secondary education, university education and teacher education (organized by IFIP WGs 3.1 and 3.3) and provided a forum to present and to discuss research, case studies, positions, and national perspectives in this field.

Man möchte, unabhängig vom Fortbewegungsmittel, schnell und sicher von zu Hause zum Hörsaal oder Seminargebäude. Eine umfassende Navigationshilfe, die alle Transportmodi verbindet, wird dafür verlangt. Das Ziel dieser Arbeit besteht darin, ein Konzept für einen multimodalen Routenplaner zu entwickeln, der es Studenten und Gästen der Universität Potsdam ermöglicht, sich zwischen den dezentral gelegenen Campusstandorten zu bewegen – egal ob mit Bus und Bahn, dem Auto, Fahrrad oder zu Fuß. Die Implementierung erfolgt ausschließlich auf Grundlage freier Daten und freier, quelloffener Software (FOSS), die für diesen Zweck aufbereitet werden. Ergebnis ist eine webbasierte Applikation, die über eine Entwicklerschnittstelle (API) in andere Projekte eingebunden werden kann. N2 - For Potsdam University students, navigation through space on a regular basis belongs to everyday life. There is a need for getting from one place to another as fast and as safe as possible, regardless of the means of transportation. A comprehensive navigational aid that connects any mode of transport is required. The aim of this thesis is to develop a concept for a multimodal trip planner, allowing students and guests of the University of Potsdam, to move between the decentralized campus locations – whether by bus and train, car, bike or on foot. The implementation is done solely based on free data and free open source software (FOSS) which are processed for this purpose. The result is a web-based application, integrated with a developer interface (API) to use in other projects.

A1 - Siegel, Anne T1 - Learning Boolean logic models of signaling networks with ASP JF - Theoretical computer science N2 - Boolean networks provide a simple yet powerful qualitative modeling approach in systems biology. However, manual identification of logic rules underlying the system being studied is in most cases out of reach. Therefore, automated inference of Boolean logical networks from experimental data is a fundamental question in this field. This paper addresses the problem consisting of learning from a prior knowledge network describing causal interactions and phosphorylation activities at a pseudo-steady state, Boolean logic models of immediate-early response in signaling transduction networks. The underlying optimization problem has been so far addressed through mathematical programming approaches and the use of dedicated genetic algorithms. In a recent work we have shown severe limitations of stochastic approaches in this domain and proposed to use Answer Set Programming (ASP), considering a simpler problem setting. Herein, we extend our previous work in order to consider more realistic biological conditions including numerical datasets, the presence of feedback-loops in the prior knowledge network and the necessity of multi-objective optimization. In order to cope with such extensions, we propose several discretization schemes and elaborate upon our previous ASP encoding. Towards real-world biological data, we evaluate the performance of our approach over in silico numerical datasets based on a real and large-scale prior knowledge network. The correctness of our encoding and discretization schemes are dealt with in Appendices A-B. (C) 2014 Elsevier B.V. All rights reserved.

BT - Towards a suitable Classroom Language and Terminology of CS for Teaching JF - KEYCIT 2014 - Key Competencies in Informatics and ICT N2 - To communicate about a science is the most important key competence in education for any science. Without communication we cannot teach, so teachers should reflect about the language they use in class properly. But the language students and teachers use to communicate about their CS courses is very heterogeneous, inconsistent and deeply influenced by tool names. There is a big lack of research and discussion in CS education regarding the terminology and the role of concepts and tools in our science. We don’t have a consistent set of terminology that we agree on to be helpful for learning our science. This makes it nearly impossible to do research on CS competencies as long as we have not agreed on the names we use to describe these. This workshop intends to provide room to fill with discussion and first ideas for future research in this field.

JF - KEYCIT 2014 - Key Competencies in Informatics and ICT N2 - This paper focuses on the results of the evaluation of the first pilot of an e-mentoring unit designed by the Hands-On ICT consortium, funded by the EU LLL programme. The overall aim of this two-year activity is to investigate the value for professional learning of Massive Online Open Courses (MOOCs) and Community Online Open Courses (COOCs) in the context of a ‘community of practice’. Three units in the first pilot covered aspects of using digital technologies to develop creative thinking skills. The findings in this paper relate to the fourth unit about e-mentoring, a skill that was important to delivering the course content in the other three units. Findings about the e-mentoring unit included: the students’ request for detailed profiles so that participants can get to know each other; and, the need to reconcile the different interpretations of e-mentoring held by the participants when the course begins. The evaluators concluded that the major issues were that: not all professional learners would self-organise and network; and few would wish to mentor their colleagues voluntarily. Therefore, the e-mentoring issues will need careful consideration in pilots two and three to identify how e-mentoring will be organised.

The following keynote addresses important issues of shaping a CSE competence model especially in the area of informatics system comprehension and object-oriented modelling. Objectives and research methodology of the project MoKoM (Modelling and Measurement of Competences in CSE) are explained. Firstly, the CSE competence model was derived based on theoretical concepts and then secondly the model was empirically examined and refined using expert interviews. Furthermore, the paper depicts the development and examination of a competence measurement instrument, which was derived from the competence model. Therefore, the instrument was applied to a large sample of students at the gymnasium’s upper class level. Subsequently, efforts to develop a competence level model, based on the retrieved empirical results and on expert ratings are presented. Finally, further demands on research on competence modelling in CSE will be outlined.

Im Lehrmodul „Interaktionsdesign“ an der Universität Hamburg werden von Studierenden innerhalb von drei Wochen prototypische Interaktionskonzepte für das Spiel Neverball entworfen und praktisch umgesetzt. Anders als in den meisten Grundlagenkursen zur MCI werden hier nicht Mock-Ups, sondern lauffähige Software entwickelt. Um dies innerhalb der Projektzeit zu ermöglichen, wurde Neverball um eine TCP-basierte Schnittstelle erweitert. So entfällt die aufwändige Einarbeitung in den Quellcode des Spiels und die Studierenden können sich auf ihre Interaktionsprototypen konzentrieren. Wir beschreiben die Erfahrungen aus der mehrmaligen Durchführung des Projektes und erläutern unser Vorgehen bei der Umsetzung. Die Ergebnisse sollen Lehrende im Bereich MCI unterstützen, ähnliche praxisorientierte Übungen mit Ergebnissen „zum Anfassen“ zu gestalten.
