Digital Native vs. Digital Literate

• Digital literacy – effective acquisition and utilization of knowledge using 21st century digital technology

• Studies by Kennedy et al., 2008 and Ladbrook & Probert, 2011 have shown that digital natives are not digital literates

• New skills – digital fluency


Roles of ICT• Enabling learners – to become drivers of their own learning in a

connected environment, – to become creators and contributors of

knowledge

• Key Enablersi. Access to learning resources, communication

and collaborative tools ii.High speed connectioniii.Authoring tools – hard and software

What the students expect?- Studies and reports by

EducauseStudyBlueGartnerIDCPew InternetMalaysia’s MCMC


Educause Study, Feb 2013

• Ubiquitous Wireless is expected–6 out of 10 students own smart

phones–80% had broadband at home–mainly for learning,

communication and entertainment


StudyBlue Study 2011

• Ubiquitous and instantaneous access to knowledge resources is critical for best possible learning experience– Smartphone users study 40 mins more per

week– Study while on the go, in the bus, waiting– 50% (out of 1 million) study while going to

bed, waking up or staying in line– 19% study in the bathroom


Pew Internet Study, 2013

• Age 18-29 : 95% have access to broadband (home + smartphone)

• 80% at home• 80% smartphone

• Mass adoption of teleconferencing and distance learning by 2020

• 57% of American adults use their cell phone to go online.

• 21% of cell phone owners say they mostly access the internet using their phone.

Gartner, 2013

•Massive Open Online Courses (Cousera, edX, Udacity) spectrums now include degrees, credits, credentials and knowledge•MOOCs are favoured due to economic pressure

IDC Study, 2013

• 29.1% sales growth of connected device

• 78.4% tablets (2011 to 2012 sales)– 128 mil tablets

• 27.1% smartphone– 918 mil units

• PC desktops and portables sales declined

Educause Study, 2012

• Blending modalities and engaging learners is a winning combination.– Students expect their instructors to use technology to

engage them in the learning process

• The time has come to move beyond thinking about individual platforms and devices. – Students want to access academic progress information

and course material via their mobile devices

• Students believe technology is critical to academic success and future accomplishments.

• Students want multiple communication options for different purposes and audiences. – use social networks for interacting with friends more than

for academic communication. – Use e-mail, face-to-face interaction, and using the

course/learning management system for academic matters

Malaysia Digital Outlook• Population - 29.71 mil• Households - 6,895,000• Broadband penetration rate

– 22.3 per 100 inhabitants– 66.8 per 100 households

• KL, Putrajaya, Penang > 80% (at par USA)• Sabah, Sarawak, Kedah 54 to 56%• Kelantan 43%• Urban 82.2% Rural 17.8% (2011)

– 1.74 million non-households subscriptions– 4,210 villages with wifi hotspots– 34,372 urban wifi hotspots

Source: MCMC Communications and Multimedia Pocket Book of Statistics Q2 2013

Cellular Telephone Subscriptions

• Total 42.6 million (Q2 2013)– Postpaid 7.5 mil– Prepaid 35 mil– Total rate 143.4 per 100 inhabitants


So what do they want?• Ubiquitous Learning– Study in bed, bathroom, while in line waiting, during

exercise (?)– Expect connections all the time, using smartphone to

access LMS and materials• Wifi hotspots• 3G/4G coverage

– Gen Wifi (?)

• Personal space/ environment– Separate communication channel for academic and

social networks– Use of OER, edu games (MOOCs ?)– Blended learning and engagement

Roles of ICT• Enabling learners – to become drivers of their own learning in a

connected environment, – to become creators and contributors of

knowledge

• Key Enablersi. Access to learning resources, communication

and collaborative tools ii.High speed connectioniii.Authoring tools – hard and software

Key challenges/issues to great student learning experience


Issue #1: OER• Open educational resources are media rich

learning objects/materials, bandwidth hungry– Eg. streaming videos, SCORM packages– Smartphone requires wireless

• Wifi hotspots, 3G or 4G• best effort type of connections

– Good HD streaming requires min 512 kbps at all time– More users connecting to the wifi access point,

negative effects on the speed• Loss of connection or jagged video streams

• CDN unicast for VOD is too costly and out or reach for many– Over wifi ?

Issue #2: Small smart devices• Multiple device types, own devices• Increasing popularity for internet access due to

cheaper android devices– Unlike iOS, Androids older devices locked at outdated

versions - firmware not supported (?)• No Security patches

• Wifi / Wireless LAN is the primary access layer– AP must BYOD-ready

• BYOD policy must be in placed to balance the need for security and control with enabling ubiquitous learning environment

• QoS for video streaming increases access contention ratio. Bandwidth is still expansive

Issue #3: Learning Contents• Flash based LO is no longer supported in Android

4.4 (Apple iOS dropped support for Flash since its inception)

– Different development for different device type is not sustainable. Different OS, iOS vs Android?

• Multi devices, multi screen sizes, multi OSes (desktop, notebook, iPad, iPhone, Galaxy etc).– LMS’s web not shown properly on small, low resolution

screens– Different apps for different OSes. Not sustainable.– Developers’ headache?

• SCORM’s incompatibility with HTML5, the new multiple devices web coding

Issue #4: Apple vs. Samsung

• Which one to start first? Mobile developers’ nightmare?

• Win 8.1?

The Takeaways


The Solutions are here, or soon.1. Video streaming/VOD over best effort networks like wifi

and 3G is now possible using Octoshape Infinite HD multicast– TM IPTV, 1MalaysiaTV, UTM-TV

2. New wifi standards, the IEEE802.11n and 802.11ac offer 450 Mbps to 1.5 Gbps– Now possible to set QoS without effecting too much on

contention ratio

3. LTE 4G is here to complement Wimax “4G”. More spectrums, more capacity, more coverage for true ubiquitous access via smartphones. Increases speed from typical 2 Mbps to 300 Mbps (theoretical).– QoS is still not possible (best effort) but not an issue, for now.

Different learner’s experience with different devices

Solution: HTML5

4. HTML5 gives us an environment that runs across mobiles and laptops

5. New SCORM called Tin Pan, is now compatible with HTML5

BYOD Mobile Security

• Uncharted territory like the wild wild west• Blackberry and iOS (jailed) are enterprise ready.

Enterprise AV for iOS is available • Androids are wild west and iOS is Legoland.

Apps can be uploaded to the devices from numerous sources.

• U.S. Government has recently Issued warning about security on Android phones• Android accounts for 79 percent of mobile

malware, while Apple’s iOS accounts for 0.7 percent

• Use of BYOD-ready access points is a must

UTM JB Campus Digital Health

• 2 Gbps internet gateways– 1 Gbps for Library, Faculty and Admin buildings– 1 Gbps for 17 residential colleges on top of 400 Mbps

microwave for Wimax

• Wifi 802.11n is being deployed to residential colleges to guarantee minimum 512kbps downlink suitable for video streaming (flipped classroom ready)– Over 2,500 access points for 20,000 students– Aruba AP, with leading security and BYOD-ready – 4G Wimax and giganet backhaul

• Wimax 4G dongles will be deployed to non-resident PG students to enable in-campus learning experience

• Wimax 4G coverage 80% geographically• LTE 4G is being deployed with >80%

coverage with much larger capacity– 2 LTE providers

• 3G data services are offered by all operators• 100 Mbps Metro E from UTMKL to JB

Campus– 400 Mbps ++ internet gateway– 100% Wimax 4G coverage
