Master Thesis in Digital Media

Title: Semi Automated Scoring Support in Technology based Assessment
Categories: Technology Based Assessment, Item Development, Algorithm Design, Reliability Analysis.
Supervisors: Prof. Dr. Karsten Wolf, Prof. Dr. Andreas Breiter

Summary

Develop and evaluate an algorithmic approach to partially evaluate results in a spreadsheet. The results are intended to support a human coder. A great challenge was to respect the extensive model with evaluation rules (determined by third parties).

The inter-coder reliability between a human group and the machine rating has been analyzed and evaluated. Finally, a qualitative analysis of the inter-coder reliabilities has been applied. Conclusions for the algorithm as well for the overall proceeding have been drawn for future efforts in this field.

Student Assistant

Project: otu.lea – Online Diagnosis for Workforce Literacy Development
Supervirsors: Prof. Dr. Karsten Wolf, Dipl.-Päd. Ilka Koppel
Position: Student Assistant

Project Description

otu.lea is a German diagnosis software for functional illiterates and persons below PISA level one. It allows to assess the fundamental levels of reading, writing, math and understanding spoken language. The tests are build upon the lea portfolio. It has been designed and tested together with the target group to adequately address their needs in terms of usability and accessibility. Every textual occurrence is supported by visual and aural informations to overcome dependencies on reading abilities.

Project Roles
  • Developed the software design based on an existing architecture
  • Implemented the majority of the software (Adobe Flex, about 15000 lines of source code)
  • Implemented the server connection (php)
  • Blackbox / whitebox testing
  • Usability testing with target group
  • Documentation
  • Co authoring a publication
