Enhanced Learning

This chapter deals with the application of Model-Driven Engineering and Model-Driven Architecture approaches in a Technology Enhanced Learning (TEL) context. Such Software Engineering approaches provide concrete benefits (productivity, interoperability, adaptability) by means of intensive uses of models, meta-models and transformations. Such benefits can also be met in a TEL context. Because computer scientists or engineers cannot currently find well-defined frameworks about this new trend, we have chosen to report recent results of our working group (initiated in 2003) in order to provide readers with a survival kit. Our results, illustrated in this chapter, argue that Model Driven Engineering can help designers to reduce the gap between specific instructional requirements (domain point of view) and the software architectures that practically support the implementation, the run-time and the regulation of this instruction.

Enhanced Learning

Capstone project-based courses offer a favorable environment for the development of student skills through an approach incorporating theoretical and practical components. However, it is often difficult to successfully coordinate between students, stakeholders, and the academic team. The absence of suitable tools for addressing this issue, along with time constraints, often prevents students from attaining the expected course outcomes. This raises the question “How can we improve project management skills in computing majors through the use of technology-enhanced learning environments?” This paper presents a Cloud-based mobile system for supporting project management under a framework of best practices in software engineering capstone courses. The Kanban approach was used as a core of the proposed system. Kanban boards are very popular in the software industry today. It has been empirically shown that they provide increased motivation and project activity control due to their inherent simplicity. This helps the students and academic team be aware of the project context as it aids in preventing ambiguities, flaws, or uncertainties in the development of software artifacts.

Abstract The purpose of this paper is to explore the main barriers and enablers for integrating technology enhanced learning (TEL) into a business organization based on a responsive paradigm. The study is based on a current literature review on challenges and learners’ needs for TEL and the preconditions for TEL curriculum integration into business organizations. The theoretical study is matched with a qualitative research on learners’ needs for TEL in two international business organizations from IT sector. Technology enhanced learning (TEL) is tackling different barriers for learning in organizations. However, to make it effective, specific technological and teaching solutions must be implemented. The research revealed that companies’ employees give preference to TEL than other forms of learning, and defined specific requirements for successful technology enhanced learning integration into business organisations. A theoretical literature review is followed by empirical findings of a qualitative research (focus group interviews) in two international IT companies. The findings of the research offer valuable insights for a responsive TEL integration into business organizations from the point of view of companies’ employees.

Model-Driven Engineering (MDE) is an approach to software development that uses models as primary artifacts, from which code, documentation and tests are derived. One way of assessing quality assurance in a given domain is to define domain metrics. We show that some of these metrics are supported by models. As text documents, models can be considered from a syntactic point of view i.e., thought of as graphs. We can readily apply graph-based metrics to them, such as the number of nodes, the number of edges or the fan-in/fan-out distributions. However, these metrics cannot leverage the semantic structuring enforced by each specific metamodel to give domain specific information. Contrary to graph-based metrics, more specific metrics do exist for given domains (such as LOC for programs), but they lack genericity. Our contribution is to propose one metric, called s, that is generic over metamodels and allows the easy specification of an open-ended wide range of model metrics.

And Control

When developing a software system, there are a number of principles, paradigms, and tools available to choose from. For a specific platform or programming language, a standard way can usually be found to archive the ultimate system; for example, a combination of an incremental development process, object-oriented analysis and design, and a well supported CASE (Computer-Aided Software Engineering) tool. Regardless of the technology to be adopted, the final outcome of the software development is always a working software system. However, when it comes to software reengineering, there is rather less consensus on either approaches or outcomes. Shall we use black-box or white-box reverse engineering for program understanding? Shall we produce data and control flow graphs, or some kind of formal specifications as the output of analysis? Each of these techniques has its pros and cons of tackling various software reengineering problems, and none of them on its own suffices to a whole reengineering project. A proper integration of various techniques capable of solving a specific issue could be an effective way to unravel a complicated software system. This kind of integration has to be done from an architectural point of view. One of the most exciting outcomes of recent efforts on software architecture is the Object Management Group’s (OMG) Model-Driven Architecture (MDA). MDA provides a unified framework for developing middleware-based modern distributed systems, and also a definite goal for software reengineering. This chapter presents a unified software reengineering methodology based on Model-Driven Architecture, which consists of a framework, a process, and related techniques.

Model-driven software engineering (MDE) has the basic assumption that the development of software systems from high-level abstractions along with the generation of low-level implementation code can improve the quality of the systems and at the same time reduce costs and improve time to market. This chapter provides an overview of MDE, state of the art approaches, standards, resources, and tools that support different aspects of model-driven software engineering: language development, modeling services, and real-time applications. The chapter concludes with a reflection over the main challenges faced by projects using the current MDE technologies, pointing out some promising directions for future developments.

The Cost

Model-Driven Engineering uses models in various stages of the software engineering. To reduce the cost of modelling and production, models are reused by transforming. Therefore the accuracy of model transformations plays a key role in ensuring the quality of the process. However, problems exist when trying to transform a very abstract and content dependent model. This paper describes the issues arising from such transformations. Solutions to solve problems in content based model transformation are proposed as well. The usage of proposed solutions allowing realization of semi-automatic transformations was integrated into a tool, designed for OPC/XML drawing file transformations to CySeMoL models. The accuracy of transformations in this tool has been analyzed and presented in this paper to acquire data on the proposed solutions influence to the accuracy in content based model transformation.
