Cloud-based services are constantly evolving. Many of the so-called
cloud services, traditionally known as Web 2.0 services because of
their innovative features, have added an important element to the
cloud landscape, which is interoperability features, opening their
APIs to allow consumers to use their services in creative and
innovative ways. This opens the possibility to create orchestrated
services that provide learning experiences, which were not possible
before. This also changes the paradigm from a monolithic architectural
approach of education environments to a flexible, distributed and
heterogeneous architectural setting for education environments, which
is the aim of cloud education (learning and teaching)
environments. This also maximizes innovation possibilities, allowing
interoperability of the best and most appropriate cloud services based
on learning needs, freeing up from a vendor specific approaches and
limits, transforming the cloud education environment into a digital
educational ecosystem of services and resources available for the
practitioners, in contrast to a large amount of software services that
are difficult to manage and organize for a learning setting.
In this special issue, we present contributions related to
this field, especially relevant descriptions about the type cloud of
services and how to address re-use of components. Three different and
complementary architectures are described, first an initial approach
for cloud interoperability service, which addresses general
interoperability of cloud-based services within a learning
environment.
Second, an affective-based recommendations
architecture. Third, a generic framework for the coordination of
pedagogical services. Additionally, the theoretical framework for a
relevant topic, inquiry-based learning using cloud services. With
regards to cloud computing approach, also a remote laboratory
architecture is presented.
Finally, most of the publications of this special issue present
several rich use cases for different contexts of the use of
cloud-based services for educational scenarios, varying from a range
of students, countries (including, Europe, Guatemala and some other
Latin American countries), pedagogical approaches, type of tools,
environments (cloud education environments, personal learning
environments, traditional LMS), evaluation perspectives (usability,
emotions, acceptance, etc.).
The first paper, from Marc Jansen et al "Using Cloud Services to
Develop Learning Scenarios from a Software Engineering Perspective"
presents the integration of cloud services within educational
scenarios. It describes the cloud-based: communication services,
repository services, production services, and processing services. It
then presents a software engineering perspective on cloud services for
learning applications with the re-use of software and infrastructure
components. It also provides some examples like the integration of
mobile contributions, and learning of signal propagations
patterns. Finally, the paper addresses the interoperability and
scalability scenarios.
The second paper from Rocael Hernandez Rizzardini et al. "Cloud
Services, Interoperability and Analytics within a ROLE-enabled
Personal Learning Environment", presents an initial architecture of
cloud interoperability services that is compound of 3 layers: business
logic, analytics, authentication; and the use of a set of cloud-based
services for learning activities through widget technology. It then
elaborates on the use cases of Galileo University in Guatemala,
measuring factors such as ease of use, emotional aspects, and behavior
analytics.
In their paper "A Generic Architecture for Emotion-based Recommender Systems in Cloud Learning Environments" Derick Leony et
al., give a generic architecture for cloud learning environments that
provides to the learner an affective-based recommendation of cloud
services (learning resources or activities), which can be utilized for
the learning process.
The contribution by Alexander Mikroyannidis et al. "weSPOT: A Personal and
Social Approach to Inquiry-Based Learning" presents a practical and
novel use of cloud-based tools to perform scientific
investigations. It utilizes cloud Web 2.0 services and social networks
to enhance the inquiry process. Future results will be of great
interests and potentially useful for the scientific community.
Rafael Pastor et al. "Laboratories as a Service (LaaS): Using Cloud Technologies in the Field of Education" presents the most cloud
computing related paper in this issue. It presents a remote
laboratories framework, providing remote laboratories as a service and
explaining its resource provisioning.
Ricardo Queirós et al. "Ensemble - an E-Learning Framework"
presents a framework focused on the teaching-learning process through
the coordination of pedagogical services. It also presents to domains
of evaluation, together with an architectural model, data model,
integration model and evaluation model.
The paper by Sylvana Kroop "Evaluation on Students' and Teachers' Acceptance of Widget- and Cloud-based Personal Learning
Environments" presents research in the area of Personal Learning
Environments (PLEs). More specifically, results of attitudes and
acceptance reasons of using widgets that contain cloud-based learning
resources or activity services are presented, emphasizing that the
essence is to be efficiently supported in the learning needs.
We would like to thank all the reviewers for their valuable input, as
well as the authors, who at all times pursued the best
quality. Special thanks to J.UCS managing editor Christian Gütl,
for his guidance and to Dana Kaiser assistant editor for all the help
during the process. Also special thanks to Dr. Eduardo Suger for
supporting Galileo University in being part of the J.UCS consortium
and to Hermann Maurer for opening the opportunity to join in.
Finally, we hope all our readers enjoy, learn and further research,
share and collaborate their cloud-based education experiences!
