Abstract:The Reload Learning Design Editor (LDE) is an Open Source, close-to-specification, treebased Learning Design (LD) editor written in Java using the Eclipse platform. The editor tools are complemented by a LD Player, which provides a familiar and user-friendly interface to the CopperCore LD runtime engine. This paper will describe the history and design rationale underpinning the tools, show how they fit into the LD authoring tools framework devised by Griffiths et al. (2005) and consider their suitability to various user roles and design approaches. The paper will conclude by outlining future versions of the software and how these new developments should facilitate the creation and manipulation of Units of Learning by staff in all user roles.

Despite several efforts for simplifying the composition process, learning efforts required for using existing mashup editors to develop mashups remain still high. In this paper, we describe how this barrier can be lowered by means of an assisted development approach that seamlessly integrates automatic composition and interactive pattern recommendation techniques into existing mashup platforms for supporting easy mashup development by end users. We showcase the use of such an assisted development environment in the context of an open-source mashup platform Apache Rave. Results of our user studies demonstrate the benefits of our approach for end user mashup development.

The placements and internships are one of the main paths to get professional background and some skills for students, especially in areas like informatics and computer sciences. The European-funded VALS project tries to promote the virtual placements and establish a new initiative in virtual placements called Semester of Code. This initiative binds higher education institutions, students, companies, foundations and Open Source projects in order to create virtual placements and solve needs that they have in relation with those placements. This paper introduces some projects about virtual placements that other institutions and companies perform, also the paper describes the needs, opinions and considerations about the virtual placements for each stakeholder involved in the placements, to finally explain the design decisions and actions behind the Semester of Code, and how they are intended to get better virtual placements and successful results.
