Massive Open Online Courses (MOOCs)

Integrating learning materials Within Open

services: Extension Approach

Building Learning Environments with Open

Services: Mashup Approach

Conclusions and Future Work

Massive Open Online Courses (MOOCs) is a

new tendency of environment for

supporting learning and Open Services

could be used for its implementation

Motivation

MOOCs

Massive Open Online Course

Distributed shared space for learning

Large-scale feedback and interaction

Open and Online: free and universal access

But have rules: at the end is a Course

Examples

Coursera (https://www.coursera.org/)

Udacity (http://www.udacity.com/)

edX (https://www.edx.org/)

Miríada X (http://miriadax.net/)

Motivation

MOOCs

Stephen Downes (2011)

xMOOCs (Cursera, edX)

Formal (traditional)

Structured

Centralized discussion forum support

cMOOCs (CCK-Style)

Distributed

Chaotic

Learners create and share artefacts

Often blog, forum or personal space

Motivation

MOOCs

Multiple services Centralized: forums, mails

Decentralized: social media (blogs, social networks, …)

Content Fragmented - distributed resources - Sharing

Format - short video (Multimedia) lectures

Learners Foster Autonomous, Self-regulated

Peer-learning

Knowledge is generative

Assessments Quiz, test, creation artefact, peer-commented

Learning analytics

Motivation

MOOCs and Open Services

Technology for running MOOCs is still

underdeveloped (George Siemens, 2012)

Heterogeneous environments

Development and integration of open materials

In this context, Open Services is a

opportunity for constructing low cost,

scalable and adaptable infrastructure.

Motivation

It is any free-access functionality with a

well-known interface implemented by

third-party vendors.

Open Services

Open Services for Educational

Environments

OAuth 2.0

Authorization protocol

Services from Google

UserInfo: basic user information

Calendar: managing dates and events

Drive: storing and documents online-edition

Picker: modal windows (file open dialogs)

Mail: gmail account

Analytics: statistics reports

Open Services

Open Services for Educational

Environments

Skype

As communication platform

Facebook

Connection with profile information

Communications (Activity Feed)

Notification, events, storing files (photos+)

Sharing (Like box, Like button, Shared Activity, …)

Youtube

Searching

Storing video content

Player: control and events capture

Open Services

Integrating Resources

In education, a resource must be an active

element, i.e. interactive and measurable

Three approaches

Through embedded objects

Extending the functionality of an existing

platform

Creating new learning environments based on a

mashup approach

Open Services

Study Cases

Embedded Object Approach

Iframe is used to connect both Systems

Put together several user interfaces

Study Cases

Social Media Learning System

(SMLearning)

It is a collaborative learning environment for

supporting the construction of interactive-

multimedia objects (Claros & Cobos, 2012)

Integrates Services from Facebook and Youtube

Mashup Approach

Building Learning Environments with Open

Services

Model-Driven approach

Design an application without deal directly with

web programming languages like JavaScript, JSP,

Java or HTML

Modeling language: concept of domain not

technology

Based on METADEPTH modeling tool (Lara et.

al, 2010)

AnaliticsStudy Cases

Each API presents methods for recover user interaction information, but is limited

E.g. Google Drive: get comments

GET_https://www.googleapis.com/drive/v2/files/{FILE_ID}/comments?key={YOUR_API_KEY}

Google analytics

Shows reports of the use of other APIs, e.g. Drive and Calendar APIs.

Conclusions and Future Work

Conclusions

We have presented three approaches for supporting

integration of Open Services into educational

environment. The use of open services enables scalable

solutions, appropriate for their use in MOOCs.

Integration of Open Services reduces developing time

and complexity, but requires review aspects such as

privacy and heterogeneity of graphical styles.

The new Web services demands better capabilities in

the browsers.

Conclusions and Future Work

Future Work

Improve our implementations and generalize our

architectures

Integration of useful services

Mendeley, http://www.mendeley.com/,

Wikipedia (http://www.wikipedia.org/,

Diagrammatic web environments like Cacoo

https://cacoo.com

Integrate the two presented applications.
