Comparing light sensors

As one of the first mission I am planning to create is a sense-it mission that measures the sunlight in different countries of Europe, the light sensors in various devices should be checked and scaled if needed. For this purpose, I created a mission that compares light sensors from different devices. The mission can be found here.

Inquiring Rock Hunters poster paper in Open Learning and Teaching in Educational Communities, Springer, available here.

Abstract: The Inquiring Rock Hunters project is an example of Citizen Inquiry. Adult citizens designed and ran their own investigations in geology, through the online platform called nQuire, while collaborating with scientists. Analysis of the investigations shows patterns of collaboration and mentoring between novice, intermediate and expert geologists, however further work is needed to create a self-sustaining community of inquiry.


Weather-it: The potential of a weather community

As the results of Inquiring Rock Hunters suggest a more intensive exploration of communities of practice and online communities, I’ve done some literature survey on these. The findings when applied may help build a self-sustaining community with a steady or increasing number of members and interactions.

Examining the Life Cycle of a community, by observing the activities and the growth, helps in monitoring the community and adjust the approaches in order to keep it active. In each stage the members have different needs and it is necessary to employ different tools, technologies or management activities; it is believed that this approach leads to success more efficiently (Iriberri & Leroy, 2009).

The Life Cycle stages found in literature are Continue reading


Weather-it: Technology Requirements

After “weather” was chosen as an attractive topic for the community, the next step is the selection of the appropriate technology which will support it. Weather-it will be an online community, so apart from the usability of the technology, we should also take into account the sociabilty aspect. According to Preece (2000), sociability has three main components: purpose, people and policies.

First of all, the community should look attractive and professional, as it is significant motivation for the members to join (Fogg et al., 2003) and use it (Van der Heijden, 2003).  Continue reading


ECTEL 2013 Doctoral Consortium Presentation

My prezi presentation for the paper “A design-based study of Citizen Inquiry for geology

Abstract: Citizen Inquiry forms a new method of informal science learning and aims to enable the engagement of citizens in online scientific investigations. Citizen Inquiry combines aspects from Citizen Science and Inquiry-based learning and is implemented through a community of practice where people having a shared interest interact and exchange knowledge and methods supported and guided by online systems and tools within a web-based inquiry environment. To explore the potential of Citizen Inquiry, a series of design-based studies will be developed to help in understanding and improving the engagement of citizens in online scientific investigation. “Inquiring Rock Hunters” is the first design-study of Citizen Inquiry, applied to Geology, and it explores the experience of participants with inquiries, other participants and tools.
