Document collections in e-learning can cause issues to both learners and teachers. On one hand, inquiry from the vast corpus of available resources is non-trivial without adequate formulation support and semantic information. Implicit links between documents are hardly understood without a proper visualization. On the other hand, it is difficult for teachers to keep track of the topics covered by a large collection. In this paper, we present an ontology coverage tool and document browser for learning material exploration. Both learners and teachers can benefit from a visualization of an ontology and the documents related to the comprised concepts, overcoming the limitations of traditional file explorers. Guiding users through a visual query process, learners can quickly pinpoint relevant learning material. The visualization, which has been implemented as a web application using the D3.js JavaScript library, can be integrated into different e-learning applications to further enhance the workflow of learners. Finally, teachers are provided an overview of topic coverage within the collection. [less ▲]

Learning Resource Management through Semantic Annotation Features in Popular Authoring Software

The ever-growing set of learning material challenges both students and teachers. While students often need to quickly retrieve resources on a certain topic, teachers have to author high quality documents in a limited amount of time, preferably using their favourite tools. In this paper, we propose an open ecosystem of plugins for popular authoring software, enabling teachers to annotate learning resources using domain concepts from ontologies. In addition, a plugin for the Moodle Learning Management System extracts these annotations from the metadata of the provided resources to allow students to get an overview of important concepts and efficiently retrieve corresponding material.

An Extensible and Lightweight Modular Ontology for Programming Education

Semantic web technologies such as ontologies can foster the reusability of learning material by introducing common sets of concepts for annotation purposes. However, suggesting learning material from an open, heterogeneous corpus is a nontrivial problem. In this paper, we propose an extensible and lightweight modular ontology for programming education. Its main purpose is to integrate annotated learning material related to programming into an IDE such as Eclipse. Our ontology is based on a modular architecture, which is extensible with respect to different programming languages. Aligning language-specific concepts with user-specific tags allows us to suggest learning resources for code elements in a fine-grained and cross-curricular way. Our concrete implementation establishes relations between learning aspects in Java or C code and annotated resources such as articles on online question-and-answer sites. [less ▲]

Concurrent Command and Consistency Management for Distributed Compound Document Authoring

Collaborative document authoring between geographically distributed users is increasingly common in our professional and personal lives. Corresponding systems aim to allow for the involvement of locally unavailable specialists while connecting familiar single-user functionality with an accessible, distributed multi-user environment. However, considering the highly dynamic processing loads on modern machines, accounting for network inadequacies, and providing a user-adjustable, mainly interruption-free work environment still presents some challenges. To address these challenges, we integrated our fine-granular data model, concurrency-based command application, and data-type specific consistency management into a distributed authoring environment. The collaboration environment provides individual sites sufficient independence to allow the local users to adapt their work experience based on personal preference and other, machine-related factors. This paper discusses our approach for a responsive, yet unobtrusive and adaptable distributed compound document authoring environment with the focus on concurrent and mainly autonomous command application and consistency management.

Distributed Document Authoring for Location-Independent Collaborative Learning

Employing computer-supported collaborative learning for cooperative problem solving or as the basis for a shared learning environment regularly entails arbitrary restrictions and requirements for the participants. Frequent interruptions to the individual’s and the group’s workflow due to transitions between data type-specific applications, the manual synchronization of one’s work, or the prerequisite of a constant server connection are common examples. In this paper, we propose the utilization of a distributed compound document authoring environment to address these issues and apply a user-centric rather than the traditional, system-focussed perspective on computer-supported collaborative learning. This includes fine-granular, real-time management and assessment functionalities for the supervisor as well as a responsive, unobtrusive and feature-rich work environment for the participants.

The retrieval of appropriate learning material from a heterogeneous, open corpus is a challenge in project-based learning. In addition, with the authoring of high-quality learning resources being a time-intensive task, reusability in different contexts is desirable. In this paper, we propose to move from a material-centric to a student-centric approach, integrating learning material in an advanced project-based learning support platform. Our ecosystem, relying on semantic web technologies, comprises plugins for common authoring and project realization tools. [less ▲]
