Software Engineering and eLearning: The MuSofT Project

eLearning supports the education in certain disciplines. Here, we report about novel eLearning concepts, techniques, and tools to support education in Software Engineering, a subdiscipline of computer science. We call this "Software Engineering eLearning". On the other side, software support is a substantial prerequisite for eLearning in any discipline. Thus, Software Engineering techniques have to be applied to develop and maintain those software systems. We call this "eLearning Software Engineering". Both aspects have been investigated in a large joint, BMBF-funded research project, termed MuSofT (Multimedia in Software Engineering). The main results are summarized in this paper.

Plattform Musikalische Bildung

Bei der Plattform Musikalische Bildung handelt es sich um ein Projekt der Hochschule für Musik Detmold. Die Plattform vereinigt in sich Ideen zum vernetzten Musiklernen, neu entwickelten Online-Musiklern-Tools sowie den Austausch und die Modifizierung dieser erstellten Kurse durch andere Dozenten und Lehrenden. Die Plattform steht allen Dozenten und Lehrern, Studierenden und Schülern an Hochschulen, aber auch Musikschulen und allgemein bildenden Schulen kostenlos zur Verfügung. Auf die Einblendung von Werbebannern wird verzichtet. Die Inbetriebnahme einer Betaversion ist im Oktober 2014 erfolgt. Weitere Ausbaustufen sind in Planung aber noch nicht gegenfinanziert.

ProFormA: An XML-based exchange format for programming tasks

Unterstützungssysteme für die Programmierausbildung sind weit verbreitet, doch gängige Standards für den Austausch von allgemeinen (Lern-) Inhalten und Tests erfüllen nicht die speziellen Anforderungen von Programmieraufgaben wie z. B. den Umgang mit komplexen Einreichungen aus mehreren Dateien oder die Kombination verschiedener (automatischer) Bewertungsverfahren. Dadurch können Aufgaben nicht zwischen Systemen ausgetauscht werden, was aufgrund des hohen Aufwands für die Entwicklung guter Aufgaben jedoch wünschenswert wäre. In diesem Beitrag wird ein erweiterbares XML-basiertes Format zum Austausch von Programmieraufgaben vorgestellt, das bereits von mehreren Systemen prototypisch genutzt wird. Die Spezifikation des Austauschformats ist online verfügbar [PFMA].

Enhancing K-12 science education through a multi-device web tool to facilitate content integration and e-infrastructure access

An effective K-12 science education is essential to succeed in future phases of the curriculum and the e-Infrastructures for education provide new opportunities to enhance it. This paper presents ViSH Viewer, an innovative web tool to consume educational content which aims to facilitate e-Science infrastructures access through a next generation learning object called "Virtual Excursion". Virtual Excursions provide a new way to explore science in class by taking advantage of e-Infrastructure resources and their integration with other educational contents, resulting in the creation of a reusable, interoperable and granular learning object. In order to better understand how this tool can allow teachers and students a joyful exploration of e-Science, we also present three Virtual Excursion examples. Details about the design, development and the tool itself are explained in this paper as well as the concept, structure and metadata of the new learning object.

Integration of SCORM packages into web games

This paper presents a model that enables the integration of SCORM packages into web games. It is based on the fact that SCORM packages are prepared to be integrated into Learning Management Systems and to communicate with them. Hence in a similar way they can also be integrated into web games. The application of this model results in the linkage between the Learning Objects inside the package and specific actions or conditions in the game. The educational content will be shown to the players when they perform these actions or the conditions are met. For example, when they need a special weapon they will have to consume the Learning Object to get it. Based on this model we have developed an open source web platform which main aim is to facilitate teachers the creation of educational games. They can select existing SCORM packages or upload their own ones and then select a game template in which the Learning Objects will be integrated. The resulting educational game will be available online. Details about the model and the developed platform are explained in this paper. Also links to the platform and an example of a generated game will be provided.

Dificultades en el aprendizaje del diseño de software orientado a objetos: un estudio cualitativo longitudinal

Las compañías de desarrollo de software buscan reducir costes a través del desarrollo de diseños que permitan: a) facilidad en la distribución del trabajo de desarrollo, con la menor comunicación de las partes; b) modificabilidad, permitiendo realizar cambios sobre un módulo sin alterar las otras partes y; c) comprensibilidad, permitiendo estudiar un módulo del sistema a la vez. Estas características elementales en el diseño de software se logran a través del diseño de sistemas cuasi-descomponibles, cuyo modelo teórico fue introducido por Simon en su búsqueda de una teoría general de los sistemas. En el campo del diseño de software, Parnas propone un camino práctico para lograr sistemas cuasi-descomponibles llamado el Principio de Ocultación de Información. El Principio de Ocultación de Información es un criterio diferente de descomposición en módulos, cuya implementación logra las características deseables de un diseño eficiente a nivel del proceso de desarrollo y mantenimiento. El Principio y el enfoque orientado a objetos se relacionan debido a que el enfoque orientado a objetos facilita la implementación del Principio, es por esto que cuando los objetos empiezan a tomar fuerza, también aparecen paralelamente las dificultades en el aprendizaje de diseño de software orientado a objetos, las cuales se mantienen hasta la actualidad, tal como se reporta en la literatura. Las dificultades en el aprendizaje de diseño de software orientado a objetos tiene un gran impacto tanto en las aulas como en la profesión. La detección de estas dificultades permitirá a los docentes corregirlas o encaminarlas antes que éstas se trasladen a la industria. Por otro lado, la industria puede estar advertida de los potenciales problemas en el proceso de desarrollo de software. Esta tesis tiene como objetivo investigar sobre las dificultades en el diseño de software orientado a objetos, a través de un estudio empírico. El estudio fue realizado a través de un estudio de caso cualitativo, que estuvo conformado por tres partes. La primera, un estudio inicial que tuvo como objetivo conocer el entendimiento de los estudiantes alrededor del Principio de Ocultación de Información antes de que iniciasen la instrucción. La segunda parte, un estudio llevado a cabo a lo largo del período de instrucción con la finalidad de obtener las dificultades de diseño de software y su nivel de persistencia. Finalmente, una tercera parte, cuya finalidad fue el estudio de las dificultades esenciales de aprendizaje y sus posibles orígenes. Los participantes de este estudio pertenecieron a la materia de Software Design del European Master in Software Engineering de la Escuela Técnica Superior de Ingenieros Informáticos de la Universidad Politécnica de Madrid. Los datos cualitativos usados para el análisis procedieron de las observaciones en las horas de clase y exposiciones, entrevistas realizadas a los estudiantes y ejercicios enviados a lo largo del período de instrucción. Las dificultades presentadas en esta tesis en sus diferentes perspectivas, aportaron conocimiento concreto de un estudio de caso en particular, realizando contribuciones relevantes en el área de diseño de software, docencia, industria y a nivel metodológico. ABSTRACT The software development companies look to reduce costs through the development of designs that will: a) ease the distribution of development work with the least communication between the parties; b) changeability, allowing to change a module without disturbing the other parties and; c) understandability, allowing to study a system module at a time. These basic software design features are achieved through the design of quasidecomposable systems, whose theoretical model was introduced by Simon in his search for a general theory of systems. In the field of software design, Parnas offers a practical way to achieve quasi-decomposable systems, called The Information Hiding Principle. The Information Hiding Principle is different criterion for decomposition into modules, whose implementation achieves the desirable characteristics of an efficient design at the development and maintenance level. The Principle and the object-oriented approach are related because the object-oriented approach facilitates the implementation of The Principle, which is why when objects begin to take hold, also appear alongside the difficulties in learning an object-oriented software design, which remain to this day, as reported in the literature. Difficulties in learning object-oriented software design has a great impact both in the classroom and in the profession. The detection of these difficulties will allow teachers to correct or route them before they move to the industry. On the other hand, the industry can be warned of potential problems related to the software development process. This thesis aims to investigate the difficulties in learning the object-oriented design, through an empirical study. The study was conducted through a qualitative case study, which consisted of three parts. The first, an initial study was aimed to understand the knowledge of the students around The Information Hiding Principle before they start the instruction. The second part, a study was conducted during the entire period of instruction in order to obtain the difficulties of software design and their level of persistence. Finally, a third party, whose purpose was to study the essential difficulties of learning and their possible sources. Participants in this study belonged to the field of Software Design of the European Master in Software Engineering at the Escuela Técnica Superior de Ingenieros Informáticos of Universidad Politécnica de Madrid. The qualitative data used for the analysis came from the observations in class time and exhibitions, performed interviews with students and exercises sent over the period of instruction. The difficulties presented in this thesis, in their different perspectives, provided concrete knowledge of a particular case study, making significant contributions in the area of software design, teaching, industry and methodological level.

Math 412 - Topology with Applications

Highlights of Data Expedition: • Students explored daily observations of local climate data spanning the past 35 years. • Topological Data Analysis, or TDA for short, provides cutting-edge tools for studying the geometry of data in arbitrarily high dimensions. • Using TDA tools, students discovered intrinsic dynamical features of the data and learned how to quantify periodic phenomenon in a time-series. • Since nature invariably produces noisy data which rarely has exact periodicity, students also considered the theoretical basis of almost-periodicity and even invented and tested new mathematical definitions of almost-periodic functions. Summary The dataset we used for this data expedition comes from the Global Historical Climatology Network. “GHCN (Global Historical Climatology Network)-Daily is an integrated database of daily climate summaries from land surface stations across the globe.” Source: https://www.ncdc.noaa.gov/oa/climate/ghcn-daily/ We focused on the daily maximum and minimum temperatures from January 1, 1980 to April 1, 2015 collected from RDU International Airport. Through a guided series of exercises designed to be performed in Matlab, students explore these time-series, initially by direct visualization and basic statistical techniques. Then students are guided through a special sliding-window construction which transforms a time-series into a high-dimensional geometric curve. These high-dimensional curves can be visualized by projecting down to lower dimensions as in the figure below (Figure 1), however, our focus here was to use persistent homology to directly study the high-dimensional embedding. The shape of these curves has meaningful information but how one describes the “shape” of data depends on which scale the data is being considered. However, choosing the appropriate scale is rarely an obvious choice. Persistent homology overcomes this obstacle by allowing us to quantitatively study geometric features of the data across multiple-scales. Through this data expedition, students are introduced to numerically computing persistent homology using the rips collapse algorithm and interpreting the results. In the specific context of sliding-window constructions, 1-dimensional persistent homology can reveal the nature of periodic structure in the original data. I created a special technique to study how these high-dimensional sliding-window curves form loops in order to quantify the periodicity. Students are guided through this construction and learn how to visualize and interpret this information. Climate data is extremely complex (as anyone who has suffered from a bad weather prediction can attest) and numerous variables play a role in determining our daily weather and temperatures. This complexity coupled with imperfections of measuring devices results in very noisy data. This causes the annual seasonal periodicity to be far from exact. To this end, I have students explore existing theoretical notions of almost-periodicity and test it on the data. They find that some existing definitions are also inadequate in this context. Hence I challenged them to invent new mathematics by proposing and testing their own definition. These students rose to the challenge and suggested a number of creative definitions. While autocorrelation and spectral methods based on Fourier analysis are often used to explore periodicity, the construction here provides an alternative paradigm to quantify periodic structure in almost-periodic signals using tools from topological data analysis.

Ampliando as ações educativas dos museus por meio da formação de comunidades virtuais de aprendizagem

Este artigo tem como objetivo mostrar que é possível incentivar a aprendizagem informal em museus através da construção de comunidades virtuais, com base em repositórios de objetos de aprendizagem, ferramentas comunicacionais e produção de OAs por parte dos visitantes. O enfoque é incentivar a aprendizagem no sentido de motivar a participação/envolvimento do visitante nas atividades da comunidade virtual. Nesta perspectiva, partimos do pressuposto de que a informação, a comunicação, a interação e a cooperação são essenciais para o processo de aprender no contexto informal dos museus. Acreditamos que a interação e a cooperação são partes integrantes do processo de aprendizagem proporcionado por comunidades virtuais e que o principal recurso de aprendizagem oferecido nessas comunidades são os objetos de aprendizagem. Diante do exposto, construímos a Comunidade Virtual do Muzar e realizamos uma experimentação do ambiente de modo a verificar o quanto os visitantes são incentivados a produzir novos conhecimentos.

O museu virtual Google Art Project : um estudo de caso em contexto de ensino-aprendizagem da educação visual

A educação na arte e pela arte confere a todos os seus intervenientes a estimulação da sua criatividade e da sua consciência cultural, proporcionando meios para se exprimirem e participarem ativamente no mundo que nos rodeia. A integração das tecnologias de informação e comunicação no processo de ensino-aprendizagem veio alargar o papel que a arte pode desempenhar neste processo, promovendo novas formas de aprender, de ensinar e de pensar. Assim, a utilização de ambientes virtuais em contexto educativo tem revelado um enorme potencial, sobretudo ao nível da comunicação e da interação entre alunos e obras de arte. Neste sentido, considerou-se importante desenvolver um estudo de caso em contexto de sala de aula da Educação Visual, promovendo uma aprendizagem baseada na articulação entre a observação, interpretação e análise da obra de arte e o museu virtual. Assim o principal objetivo deste estudo foi avaliar as potencialidades do Google Art Project, enquanto objeto de aprendizagem, na promoção da aprendizagem na área da literacia em artes. Para além disso, procurámos ainda avaliar se a utilização de ferramentas multimédia como o referido Google Art Project e o Quadro Interativo, constituem fatores de motivação na aprendizagem da disciplina de Educação Visual. Do ponto de vista metodológico desenvolvemos uma estratégia baseada na investigação-ação. Procurámos, por um lado, descobrir e compreender o significado de uma realidade vivida por um grupo de alunos e, por outro lado, refletir sobre a prática educativa com o intuito de a melhorar e transformar. Este estudo envolveu cinco turmas do sexto ano do ensino público. Para a recolha de dados utilizámos técnicas baseadas na conversação e na observação, no questionário e nas notas de campo. Os resultados deste estudo revelam que as ferramentas tecnológicas utilizadas podem efetivamente contribuir para a promoção da aprendizagem dos alunos na área da Educação Visual, mais concretamente ao nível do domínio da literacia artística, da representação e da interpretação visual.

Sequential versus simultaneous viewing of an environment : effects of focal attention to individual object locations on visual spatial learning

We investigated memories of room-sized spatial layouts learned by sequentially or simultaneously viewing objects from a stationary position. In three experiments, sequential viewing (one or two objects at a time) yielded subsequent memory performance that was equivalent or superior to simultaneous viewing of all objects, even though sequential viewing lacked direct access to the entire layout. This finding was replicated by replacing sequential viewing with directed viewing in which all objects were presented simultaneously and participants’ attention was externally focused on each object sequentially, indicating that the advantage of sequential viewing over simultaneous viewing may have originated from focal attention to individual object locations. These results suggest that memory representation of object-to-object relations can be constructed efficiently by encoding each object location separately, when those locations are defined within a single spatial reference system. These findings highlight the importance of considering object presentation procedures when studying spatial learning mechanisms.

Leveraging the repository infrastructure to curate institutional heritage materials, learning objects and data assets

Developing and maintaining a successful institutional repository for research publications requires a considerable investment by the institution. Most of the money is spent on developing the skill-sets of existing staff or hiring new staff with the necessary skills. The return on this investment can be magnified by using this valuable infrastructure to curate collections of other materials such as learning objects, student work, conference proceedings and institutional or local community heritage materials. When Queensland University of Technology (QUT) implemented its repository for research publications (QUT ePrints) over 11 years ago, it was one of the first institutional repositories to be established in Australia. Currently, the repository holds over 29,000 open access research publications and the cumulative total number of full-text downloads for these document now exceeds 16 million. The full-text deposit rate for recently-published peer reviewed papers (currently over 74%) shows how well the repository has been embraced by QUT researchers. The success of QUT ePrints has resulted in requests to accommodate a plethora of materials which are ‘out of scope’ for this repository. QUT Library saw this as an opportunity to use its repository infrastructure (software, technical know-how and policies) to develop and implement a metadata repository for its research datasets (QUT Research Data Finder), a repository for research-related software (QUT Software Finder) and to curate a number of digital collections of institutional and local community heritage materials (QUT Digital Collections). This poster describes the repositories and digital collections curated by QUT Library and outlines the value delivered to the institution, and the wider community, by these initiatives.
