PD Dr. Ralf Klamma, AOR - Theses


Bachelor, Master
Blockchain-based Verification of Learning Analytics Data - Open
The goal of this thesis is to make collected Learning Analytics data, extracted from various Learning Management Systems, traceable and verifiable by keeping a reference to the monitored data on the las2peer Blockchain. The thesis should investigate related work in the domain of educational usage of Blockchain technology. The developed extension should integrate into the existing project's infrastructure and provide learners and their mentors/tutors with a tool to explore when and what kind of data was collected. By improving this traceability, we hope to increase the trust in the data collection (and its usage) from both learners and mentors.
Bachelor
Chatbot-assisted Community Analysis - Open
The goal of this thesis is a chatbot that can be used by a community to query usage data and visualizations from an existing system.
Master
Collaborative Immersive Learning Analytics - Open
Supervised by PD Dr. Ralf Klamma, AOR
Our approach is a comprehensive and evolutionary sociotechnological learning analytics and design process leading to a flexible infrastructure where professional communities can co-create their wearable enhanced learning solution.
Master
Gamification of Serious Games with Recommendation Support - Open
The goal of this master thesis is to re-design and extend an existing serious games platform as microservices for a gamification framework already realized as microservice architecture.

Measuring coherence accross media in learning environments - Open
Supervised by PD Dr. Ralf Klamma, AOR, Prof. Dr. Marc Spaniol
Multimedia content based indexing delivered a lot of models for the analysis of multimedia materials. In modern educational platforms, e.g. MOOCs and self-regulated learning platforms. In consequence, multimedia materials are produced by educational designers but also by the learners during their learning processes. Coherence is a semantic measure for the local and global connectivity of e.g. sentences, paragraphs, videos, slides among others. Computer linguistics has provided impressive results for measuring the quality of writing, e.g. for automatic essay scoring. To measure the coherence of multimedia materials many computational methods reaching from natural language processing to machine learning needs to be combined in a common coherence model. Goal of this master thesis is to co-develop a coherence model for cross-media coherence and to prototypically combine these computational methods for a webinar.
Bachelor
Persistent Association of Virtual Objects in Mixed Reality - Open
Supervised by PD Dr. Ralf Klamma, AOR; Advisor(s): Benedikt Hensen, M.Sc.
A mixed reality environment immerses users in a three-dimensional space. This allows them to organize digital content in the entire room, e.g. task cards in immersive project management. A natural way to sort related objects is by placing them close to each other. However, this kind of spatial co-location of objects is not enough to stress their relation to each other. If another user who is unaware of the association moves one of the objects, the spatial connection is lost. Hence, lines in 3D space are required which establish a visual and persistent connection between the objects. In a previous project, an initial system was implemented which uses straight lines to connect the objects. However, straight lines have some shortcomings since they intersect with obstacles between the two endpoints. A better connection system can use 3D curves to avoid the obstacles in an efficient way.
Bachelor, Master
Social Recommender Systems for Professional Communities - Open
Supervised by PD Dr. Ralf Klamma, AOR
This thesis aims to develop social recommender system service for Open Source Software (OSS) Communities.
Bachelor
Systematic Literature Reviews - Pushing the Limits - Open
Supervised by PD Dr. Ralf Klamma, AOR
A systematic literature review is a "systematic, explicit, comprehensive, and reproducible method for identifying, evaluating, and synthesizing the existing body of completed and recorded work produced by researchers, scholars, and practitioners".
