Konferensbidrag (refereegranskat)abstract
- The Vanishing & Appearing Sources during a Century of Observations (VASCO) project investigates astronomical surveys spanning a 70 years time interval, searching for unusual and exotic transients. We present herein the VASCO Citizen Science Project, that uses three different approaches to the identification of unusual transients in a given set of candidates: hypothesis-driven, exploratory-driven and machine learning-driven (which is of particular benefit for SETI searches). To address the big data challenge, VASCO combines methods from the Virtual Observatory, a user-aided machine learning and visual inspection through citizen science. In this article, we demonstrate the citizen science project, the new and improved candidate selection process and give a progress report. We also present the VASCO citizen science network led by amateur astronomy associations mainly located in Algeria, Cameroon and Nigeria. At the moment of writing, the citizen science project has carefully examined 12,000 candidate image pairs in the data, and has so far identified 713 objects classified as “vanished”. The most interesting candidates will be followed up with optical and infrared imaging, together with the observations by the most potent radio telescopes.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Formal learning in higher education creates its own challenges for didactics, teaching, technology, and organization. The growing need for well-educated employees requires new ideas and tools in education. Within the ROLE project, three personal learning environments based on ROLE technology were used to accompany “traditional” teaching and learning activities at universities. The test beds at the RWTH Aachen University in Germany, the School of Continuing Education of Shanghai Jiao Tong University in China, and the Uppsala University in Sweden differ in learning culture, the number of students and their individual background, synchronous versus distant learning, etc. The big range of test beds underlines the flexibility of ROLE technology. For each test bed, the learning scenario is presented and analyzed as well as the particular ROLE learning environment. The evaluation methods are described and the research results discussed in detail. The learned lessons provide an easy way to benefit from the ROLE research work which demonstrates the potential for new ideas based on flexible e-learning concepts and tools in “traditional” education.
