Causal mechanisms of braided river systems modelled by DynaLearn

Within the Master Thesis “Understanding physical mechanisms of braided river system development by using conceptual and qualitative systems modeling” DynaLearn is used as conceptual modelling tool at BOKU. Aim of this work is to develop a causal understanding of the different factors influencing the development of a specific morphological river type, the braided river system. A causal systems understanding is a pre-requisite for any process based management and restoration of river systems.

DynaLearn applied within the new master programme ‘Applied Limnology’ at BOKU

DynaLearn will be applied within the new master programme ‘ Applied Limnology’ at the University of Natural Resources and Life Sciences (BOKU), Vienna. Model building and exploration with DynaLearn will be performed within the course ‘Multi-scale modeling and system dynamics in aquatic ecosystems’. The course will be held as part of the module ‘Aquatic Ecosystem Modeling’. DynaLearn will be used in combination with semi-quantitative and quantitative mathematical and statistical approaches targeting at the development of a comprehensive dynamic understanding of river systems as a basis for succesful management and restoration.

Second round of evaluation studies completed at BOKU

The second round of evaluation studies has been completed at BOKU. Features studied for their efficiency were Feedback, Grounding and Basic Help. 31 university students were actively working for two afternoons according to tasks provided by a moodle course without much intervention by the teacher. Furthermore an in-depth study was run with two high school students during four days. The target of these formative evaluation studies was to assess, if the  feedback provided by DynaLearn so far is sufficient to support self directed use and learning or not. Intermediate model uploads enabled us to compare models before and after feedback was given by the repository. At the first glance, feedback from an expert model in the repository yielded significant changes in model content and structure even after a short time, indicating the potentially high benefit of this feature for learning. Pre- and post tests, as well motivation questionnaires completed the assessments with regard to learning effects, motivational issues and acceptance.

DynaLearn successfully presented at NABS 2011

DynaLearn was successfully presented at the NABS 2011 meeting in Providence within the special session Promoting evidence-based methods in environmental research and management by BOKU as multi-level tool for causal integration of evidence based data collections. As currently causal data integration is mainly done by static box-flow diagrams with links of evidence (see ‘The Causal Analysis/Diagnosis Decision Information System – CADDIS’), DynaLearn aims at providing a dynamic framework for building and sharing evidence based causal models via an online repository. It became clear, that the DynaLearn features developed so far have high potential to be also applied for professional and interactive data integration and decision support.

DynaLearn as favorite example of BOKU research

The Austrian DynaLearn-Team presents the Dynalearn project on January 18, 2011 as an favorite example of the BOKU research pool. The DynaLearn project was selected by the BOKU`s center of education togehter with the students union. Aim of lecture is to present the DynaLearn approach to bachelor and master students  delivering insights into research, methods and practice of up-to-date scientific educational work.

Second evaluation case study run at BOKU

A second evaluation case study at BOKU was run at 19.05.2010. During an afternoon session 27 students explored the physical and biological effects of river channelization and restoration with different use levels of DynaLearn. Evaluations included video taping, a pre- and post test as well as a motivation questionnaire. We want to thank all students who participated in this lecture for their kind collaboration.

First evaluation case study of DynaLearn in Austria

BOKU conducted a first evaluation of Dynalearn between 19.04.-22.04.2010 at the IHTL Bad Radkersburg. Two students, Sophie Fastian and Oliver Kindler, were working for three days with use levels 1,2 and 4 of DynaLearn, followed by an official presentation of their work at day 4. Evaluations included video taping, a pre- and post test as well as a motivation questionnaire. The evaluation results provide an important first feedback on usability and problems learners encounter with the software. We want to thank the IHTL and both students for their kind cooperation!

First evaluations of different use level functionalities of DynaLearn at BOKU

At BOKU Annemarie Jung and Maria Zacharias have started their master theses on developing models on climate change effects on river catchments and the river continuum concept using the first Beta version of the DynaLearn workbench. The detailed documentation of their first model building activities with DynaLearn will provide important feedback for the software development. Welcome to the DynaLearn team!

IHTL enters DynaLearn as Evaluation Partner

The IHTL Bad Radkersburg (Styria, Austria) aims to provide young people from Austria, Hungary, Slovenia and Croatia with a common training to become engineers. As a result of this the graduates should be able to establish and develop a cross-border market and help to promote the economy and culture of the Adria-Alpe-Pannonia Region. DynaLearn software will be introduced by BOKU to train students in a better understanding of local and global environmental issues, especially related to sustainable energy supply within European electricity networks (SmartGrids). The effects of the DynaLearn approach on learning and understanding important related scientific concepts will be evaluated in dfferent classroom settings. Welcome to the Dynalearn project!
