Open Educational Resources/geolocated OER
Even if learning resources are presented at Wikiversity as a digital media, learning processes itself taking place with interaction with your
Attach Learning Resouces to Geolocations[edit | edit source]
OER attached to Geolocations: Imagine your could attach digital Open Educational Resource to a real geolocation. The geolocation is e.g. a small river and use "Augmented Reality Tutorial" for visualization of OER:
- Attach a video that shows the place from a bird view.
- Provide a online questionnaire about the biological environmental observations at the river.
- Attach an image, how the river will look in winter.
- Visualize the work of mircro-bacteria doing work in the river.
- Show historic images of the river from the year 1912 and let the visitors analyse the human alteration in the river bed.
Wiki Products and Geolocated OER[edit | edit source]
If we analyse producte of the WikiMedia foundation for geolocation attributes, the following can be identified:
- (Language and Geolocation) language of a learning resource in Wikiversity can be to make a rough af´sssignment to a geographical area in which the language is spoken.
- Latitude/Longitude can make a reference to a Point of Interest (POI) or a building (see coordinates Vienna International Centre upper right corner of article)
- (Geonames) Denomination of a country, city, address, ...
- (Geographical Area) define an area on the globe by a sequence of several geolocations (points). Let be a point as a single longitude/latitude pair . A "triangle" is a geographical area consisting of three points :.
Learning Tasks[edit | edit source]
- (Geolocated AR) Jerome Etienne create AR.js based on the libraries Aframe and three.js. Nicolo Carpignoli worked on Geolocated Augmented Reality and merge the concept with a marker based augemented reality (see 3D Modelling). In 2020 the Open Source Augemented Reality package AR.js contains 3 different AR approaches:
- Marker based (initiated by Jerome Etienne)
- Geolocation based (developed by Nicolo Carpignoli)
- Image Tracking based (AR.js Community)
- In this context we can geolocated Open Educational Resources
- with QR-Codes at special places that encode small infomation as content directly or a reference/URL to OER that could be digital media of any kind that supports learner at the geolocation she/he is currently at.
- Augemented Reality visualizing additional content as specific geolocations (see also animated examples of AR.js on project web portal)
History of Approach[edit | edit source]
Community of Practice in the Action Team 6 Follow Up initiative and international approaches of Risk Mitigation strategies analysed the peaceful use of space technology (see UN-COPUOS). Having risk mitigation strategies for communities in mind, capacity building and learning is one of the key elements, that help organisations to support the communities exposed to risks. United Nations support that in many areas (Climate Change, Humantarian Aid, Disaster Management, Global Health). This learning resource is based on results of the community of practice in AT6FUI/EFG-SGH by piloting protoyping ideas (see AT6FUI/Expert Focus Group for Space and Global Health. But the learning resource is designed in way that generic princples like "attaching digital information to geolocation" are used as topic of the learning resource, because the generic geospatial principles can be used and transfered to other educational settings or use-cases for capacity building as well.
Geolocation OER for Risk Management[edit | edit source]
To learn about strategies to mitigate the risk includes improvement of risk literacy. The access to the open educational resources for everyone is necessary to reach people that are exposed to risks. Wikiversity provides OER and it at the same time a collaborative environment for teachers and learner. At the interface of organisational capacity building the concept of an One fits all approache does not work in general and especially not for educational resources. Language, social and cultural determinants are relevant how learner perceive risks. This implies that learning resource had to be tailored to this determinants. Wikiversity allows the alteration, remix, adaptation to local and regional requirements and constraints. So geospatial aspects are relevant for educational resources as well. Wiki products allow the attachment of articles to specific geolocation (see United Nations Building VIC in Vienna - upper right corner). The georeferencing can be used by service like http://www.geonames.org/. Based on such a service the latitude and longitude of the learber can be used find nearby learning resources in Wikiversity. Even augemented reality tools like Mixare can used along with the webservices to place geolocated learning resources digital information that make reference to geolocation where the user is.
Design Example of geolocated OER[edit | edit source]
Assume a group of learner will visit the Niagara Falls. Teacher could enrich the geolocation with additional media:
- video from a helicopter,
- looking into the past: the first snapshots of the location from beginning of photography,
- Open Literature, open poems, that refer to the geolocation,
- mircoscope views about the aquativ life,
- how will the Niagara Falls evolve in next 100000 year as projections in the future
- how does the place look in Winter, Spring, Summer, Autumn, ... temporal aspect
The geolocated OER involve learning tasks that trigger the interaction of the learner with the environment.
Images Maps - A way of visual exploration of Learning Resources[edit | edit source]
An image is a standard way for illustration of text documents. A image map attached links to certain areas on the image. Learners can click on the image and explore details and further information. A geolocated Learning Resoure can use this concept to allow exploration of a geolocation without being at this geographic location. This is helpful as a preparation for a physical visit of that place (see Real World Lab). The image on the right is a small example of on image map.
Commercial Use of tailored information for geolocation[edit | edit source]
Geolocted OER applied a basic geospatial principle to OER, which is widely used in the commercial sector:
- Games like P0K0M0N G0 allows guiding users to commercially interesting location,
- advertisments by "TwoogleBook et. al." can be placed tailored to geolocation of mobile phone user,
- travel guides can provide digital information for the geolocation/city/leisure park on mobile devices,
All application show the same generic geospatial principle:
Provide information tailored to the geolocation of the user
Extend Perspective of Teachers on the Design of Learning Resources[edit | edit source]
The use of digital devices has changed and in development countries the era of desktop computers skipped and the first computer will be mobile device. Have the geospatial principle in mind the major shift can be summarized as:
Instead of sitting in front of Desktop Computer with internet connection, the mobile device supports learners to interact with the environment they are living and working in!
The awareness of teachers about this basic geospatial principle changes the design learning resources.
(Teachers Training) Learning resources for teachers training in Wikiversity start with
- general awarness about the application of geospatial principles and
- then the learning task in teachers training is the application of the principle their own expertise and their country or region they live in.
- finally a more advanced task is to decompose the developed learning resource in parts that are applicable for other geolocations and areas as well and into parts that just refer to the specific geolocation.
Importance of geolocated OER for Risk Management[edit | edit source]
If someone lives in the Antarctica research station then it doesn't make sense to inform the researcher about malaria risks. If you're going on holiday to the Kruger National Park, then risk mitigation information is helpful about the use of mosquito repellent, Mosquito nets or take malaria prophylaxis.
App Development for geospatial OER in Wikiversity[edit | edit source]
Mixare is a good starting point to explore the possibilities of such an approach. Also the software design analysis is helpful to learn about the import of geospatial "nearby"-databases with OpenSource technology.
Looking teachers without IT background a productive use of these approach has a requirement, that with assignment of a geolocation in a Wikipedia learning resource, this learning resource or any other wikipedia article should be available in the Augmented Wiki Browser. No additional workload should be necessary for teacher to import the "nearby"-learning resource of "nearby"-Wikipedia article.
From the software development side the Mixare-approach needs the refactoring of code or a reimplementation as multiplatform application as HTML5/JS/CSS app (suggestion might be moved to a meta area of Wiki products in general).
Crowd funding could support the development of a Open Source app that allows teachers
- to use geolocated learning resources,
- place learning resource as teachers to specific geolocation and
- have something an Open Source MediaWiki Browser structural equivalent to Mixare that allows teacher to create geolocated OER just by placement of latitude and longitude in the OER.
A major improvement of Mixare is necessary mainly for the reduction the workload for teachers and not from the usability for learners to retrieve Open Educational Resource that a relevant to their CURRENT geolocation. Technically an improvement of access to mobile phone sensors especially GPS location must be tested for current devices and operating systems (stability)
Think globally, act locally[edit | edit source]
The approach "Think globally, act locally" can be applied to learning resources. Global approaches in a learning resouce lead to local or regional implementations/specialisation of OER that respects local cultural, social requirements and the local constraints to selected location as learning resource.
