Key Elements in MOOCs

Management of massive numbersUp-/down-voting in forumsAll lecturing material recordedSelf-assessmentManagement of peer2peer assessment

No use of standards

Challenge

How will both kinds of platformsevolve in the future?

Will they integrate?Will each of them take elements

from the other?

What will the educationalplatform of the future?

18/56


Web Template System

Web template:Markup (HTML, XML, )

+ code (variables, loops, )

Separates contentfrom presentation

Allows the massgeneration of web pages

Example


19/56


Brief Overview

Delimiters and escaping Data types and operators Statements Template inheritance (there is much more)

Examples taken from jinja.pocoo.org

Delimiters

Print expression{{ }}

Execute statement

{% %}

{%- %} or{% -%} (remove whitespace)# (to end of line, can span several lines if brackets)

Comment{# #}## (to end of line)

These are default, they can be changed


20/56


Escaping

Short escape: '{{ '{{' }}

Long escape: raw{% raw %} {% endraw %}

Data Types

Boolean: true, false Integer: 17 Real: 17.0 String: hi List: [list, of, objects] Tuple: (tuple, of, values) Dict: {k1: uno, k2: dos}

Cannot

be

changed

Macro (Function)

Definition

Template Inheritance

Template inheritance allows to build a baseskeleton template that contains all thecommon elements of the site and defines

blocks that child templates can override These blocks act as placeholders,

but can have content

They work in both directions Very powerful concept


26/56


Base Template

Child Template


27/56


Template Inheritance

super() refers to thecontent of the parent block

Block end tags can have the name Blocks can be nested (variables from outer

scopes can only be accessed with scoped)

Possible Projects


28/56


Possible Projects

1. User-friendliness for exercise upload2. Khan-style parametric exercises3. Peer2Peer evaluation4. Learning Analytics

(integration with Google Analytics)

5. Gamification6. Badges (Mozilla)7. Mobile native (Android) or web-based app

Project Proposal 1:

Exercise Upload


29/56


Activities & Assessments

In Googles wording, Activities are exercises that are not graded

(sometimes also calledformative assessment)

Assessments are exercises that are graded(sometimes also calledsummative assessment)

You have to be a programmer to uploadthis input into the system code.google.com/p/course-builder/wiki/

CreateActivities

code.google.com/p/course-builder/wiki/CreateAssessments

Example Activity


30/56


Suggested Improvement

To improve input, reusability, shareability,and parametrisation there might be better

ways to enter these activities and

assessments

For instance, by providing a specific editorthat generates the correct code

As an intermediate solution,using a Google Docs form

Project Proposal 2:

Khan-style Exercises


31/56


Khan-style Exercises

More powerful than the ones provided They include

Parametrized values Optional hints

Again they have to be coded explicitly However,

Juan Luis Sanz and Pedro Muoz Merino(UC3M) have written an editor (Genghis)

Pavel Simakov (Google) has developeda plugin for WordPress

Genghis (Result)

Project Proposal 3:

P2P Evaluation


34/56


P2P Evaluation

Not all subjects can be adequately evaluatedwith multiple choice exercises

Sometimes there is not one correct answer Especially in the Humanities it becomes

necessary to write an essay

To cope with massive numbers,peer to peer (P2P) evaluation is used

GCB does not support P2P evaluation

P2P Evaluation

Phases (in Coursera):1. Submission Phase (assignment)

2. Evaluation Phase (rubric)

3. Results Phase (computation)


35/56


Project Proposal 4:

Learning Analytics

Analytics

GCB proposes to analyze Reach &Engagement with Google Analytics


36/56


Analytics

One the one hand,there is no integration of both systems

On the other hand,much more information can be relevant

from a learning perspective

Project Proposal 5:

Gamification


37/56


Gamification

Use of game design techniques tosolve problems and engage audiences

Quote

"By 2015, more than 50% of allorganizations that manage innovation

processes will gamify those processes"

-- Gartner, April 2011

www.gartner.com/it/page.jsp?id=1629214

Hype Cycle

Progress!

In 2010, Harvard Business Reviewreported on the results of a study into

what motivated people at their jobs

Hundreds of people kept daily diariesover several years to identify what really

kept them motivated day-to-day

The answer, overwhelmingly,was a sense ofprogress

Elements of Gamification

Game Mechanics Constructs used in games to encourage gameplay Badges,points, leader boards, levels, challenges,

achievements, virtual sheep you can put on your farm

Game Dynamics Strategies used in game design

based on psychological motivations

Appointments oravoidance, where people dosomething to gain a reward or avoid a punishment,

free lunch dynamic, where people feel they are gettingsomething because of their behavior,

Game Mechanics

Challenges, Missions Points

Virtual currency Leaderboards Achievements

Badges, Levels Progress bar

Challenges

Clearly identifiable goals to be pursued In agreement with level of mastery Rewards for achieving challenges


41/56


Points

Experience points (XP)Never go down, not redeemable, no max

Redeemable points (RP) "earn&burn", virtual currency, legal issues

Skill points For non-core activities

Karma points Benefit for giving away

Reputation points Proxy for trust

Leaderboard

List of top achievers Put the user in the

middle Show the friends


42/56


Achievements

Virtual or physical representationof having accomplished something

Achievement badges Achievement levels

Badges

Awards for particular achievement Exposed for social recognition


43/56


Levels

Group sets of similar "players" Show status Change game difficulty in order

to remain challenging

Progress Bar

Indicates progress in an easy way Some say, progress bars should

never reach 100%

Onboarding

Simple challenges Give value before registration Let the user invite friends

Driving Engagement

4 principal means of drivingengagement using gamification:

1. Accelerated feedback cycles2. Clear goals and rules of play3. A compelling narrative4. Tasks that are challenging but achievable

Flow

Mental state of operation in which a personin an activity is fully immersed in

a feeling of energized focus, full involvement,and success in the

process of the activity.

Game Aesthetics

Aesthetics describesthe desirable

emotional responses

evoked in the players,

when they interact

with the game system.

Fun and Community

Not just points and badges! Gamification is not Pointsification

www.alittleb.it/gamification/why-gamification-is-not-a-simple-pointsfication/

8 Kinds of Fun

Sensation Game as sense-pleasure

Fantasy Game as make-believe

Narrative Game as unfolding story

Challenge Game as obstacle course

Fellowship Game as

social framework

Discovery Game asuncharted territory

Expression Game as soap box

Submission Game as

mindless pastime

Project Proposal 6:

Badges


53/56


Badges

Badges are a way to certifyattained skills or achievements

The granularity can be relatively small Mozilla offers an open framework

for representing badges It would be nice to integrate this with GCB

Mozilla's Open Badges

openbadges.org


54/56



Provides the open, core technology tosupport an ecosystem of badges

Supports a broad range of differentbadge issuers, allows any user to earn

badges across different issuers, web sites

and experiences, then combine them into

a single collection tied to their identity This collection of badges can then be

shared out to various audiences across

the web, resulting in real-world results

like jobs or formal credit



55/56


Badges for LLL

The Badges for Lifelong LearningCompetition, launched in collaboration with

the Mozilla Foundation, will focus on

badges as a means to

inspire learning,confirm accomplishment, orvalidate the acquisition of knowledge or skills.

www.dmlcompetition.net!

P2PU

P2PU assessments and badges give a way torecognize the learning that occurs at P2PU,

demonstrate skills, build reputation in the

community and eventually, get jobs

badges.p2pu.org!

Project Proposal 7:

Mobile App

Mobile Devices

GCB is not adapted to mobile devices It would be nice to have

A native app (eg. Android), orA web-based app (with HTML5)to better see the educational material
