The contextThe context

Large investments in e-learning, mainly due to time and financial reasons

Few skills inside and outside the organizations to manage the problem dimensions and urgency

Technologies have ran more than methodologies and content quality

The risk: loosing time, money and objectives The needs: raising communication and

consciousness, building affordable models, cancelling legends

The MIT roleThe MIT role The Ministry for Innovation and Technologies has set

up an internal structure, inside the CNIPA (National Centre for Informatics in Public Administration), for establishing the Italian Competency Centre on e-learning

It’s main role is to deliver common rules for e-learning in public administrations

It’s not an imposing action, but a consensus driven one

It means to analyze ongoing situations and give recommendations for reaching a common “interoperability” rules subset

Technologies, services and contents

The Working GroupThe Working Group A high-level working group has been

established to deliver, within this year: Minimal “strong” recommendations on how

to manage e-learning projects for public employees (The “Decalogo”)

Guidelines for e-learning in public administrations

“Vademecum” on these guidelines

The GuidelinesThe Guidelines

It’s a process began in the recent years (Direttiva Frattini, Government Guidelines for the IS development, Decreto Moratti-Stanca for telematic universities)

Main goals: Promoting the correct implementation of e-

learning technologies for public employees Ensuring portability and re-usability of project

deliveries Bridging, in the medium term, to the Italian

Application Profile for e-learning in public administrations

MIT – Innovazione Italia

The dimensions of the GuidelinesThe dimensions of the Guidelines Why: “light” principles on co-financed projects and

digital content for a central repository What: didactic methodologies, technologies and

services, learning objects How: international widely recognized standards and

specifications (XML, LOM, IMS SCORM, etc.), for the moment, and general recommendations on how to manage an e-learning project

Who: public administrations, technology ad content providers, final users

When: formal and operational validity from November 2003 on, de facto effectiveness yet running – CNIPA is just ruling the public e-learning projects

Official creation of the Italian Competency Centre on e-learning

Development of the “Public Administration Virtual School” Project through: A digital repository of projects (Portal) and contents

(Learning Objects DR) A LMS platform for those administration which will

choose this subsidiary service (ASP) A support system for monitoring the effectiveness of

public investments

To come in the future: implementation of the Italian Application Profile for the public administration

What we believe standars ARE todayWhat we believe standars ARE today

They are necessary in public systems They are now better than nothing They are a filter They are still in their infancy for e-learning (as well as in other

fields…) They are technology centred They are too much “USA” and US provider centred – Europe

has few independent providers and research groups They are heavy, especially for content development They are often “empty” of didactic meaning They will prove their validity only in 3/5 years when applied to

millions of people They will help technology and learning providers, not end

users, for the moment We have to work on them

What we believe standards will NOT do for usWhat we believe standards will NOT do for us

They will not solve all of our re-usability needs They will not avoid money loss in the medium term They will not assure the e-learning process effectiveness in the

actual format They are not “science” They still don’t take care of geographical particularities and

human capability of learning They are not still integrated in “ambient intelligence” They are not updated with last HW e SW technologies They are not the final answer for comparing systems among

them We don’t have to wait for someone else to develop them for us

Le criticità del presente (1)Le criticità del presente (1) Costruzione di un Profilo Applicativo

“Application profiles consist of data elements drawn from one or more namespace schemas combined together by implementors and optimised for a particular local application. Application profiles are useful as they allow the implementor to declare how they are using standard schemas. In the context of working applications where there is often a difference between the schema in use and the 'standard' namespace schema.” (Heery & Patel, 2000) Si possono usare elementi provenienti da uno o più set

Non si possono introdurre elementi inesistenti in altri set dichiarati, a meno di non creare un nuovo schema

Si possono dichiarare vocabolari e range di valori per gli elementi

Si possono raffinare in senso sematicamente più ristretto le definizioni di uno schema esistente (es. per un dominio specifico)

Il problema dell’informazione destrutturataIl problema dell’informazione destrutturata Nel mondo, ogni anno, viene prodotta informazione originale per circa 1-2 exabyte (10 18

bytes), ovvero 250 megabytes/uomo (http://www.sims.berkeley.edu/research/projects/how-

much-info/)

Internet trasmette circa 7500 Terabyte/anno di informazione digitale senza alcuna

strutturazione. La maggior parte delle informazioni appartengono al “deep Internet” (da 400

a 550 volte rispetto al “surface Internet”, 19 Terabyte)

Oggi tende a crescere esponenzialmente la quantità di materia destrutturata “born digital”.

Essa ha un “tasso di mortalità” superiore a quello della materia tradizionale (55 mesi,

http://www-class.unl.edu/biochem/url/broken_links.html)

Molta materia non digitale non viene considerata in contesti di e-learning (se non attraverso

riferimenti)

I costi di digitalizzazione/indicizzazione sono molto elevati. Spesso la costruzione di

metadati non viene neanche presa in considerazione

L’Italia ha un serio skill shortage per instructional designer (10.000) e catalogatori (x?)

Pattern matching e indicizzazione automatica di contenuti destrutturatiPattern matching e indicizzazione automatica di contenuti destrutturati

È una tecnologia che ha molteplici applicazioni “intelligenti”. Nell’e-

learning ha già un’applicazione come e-teacher

(http://wwwis.win.tue.nl/2L690)

Alcuni algoritmi matematici (es. la teoria dell'informazione di Claude

Shannon), unitamente ad alcune tecniche di analisi di dati digitali

(anche audio e video) consentono l’estrazione automatica di

informazioni rilevanti

Il passo successivo è l’indicizzazione dei contenuti attraverso la

costruzione automatica di metadati

Il processo iterativo di ricerca e ordinamento, attraverso agenti

software, consente il raffinamento dei risultati

Schemi di metadati non corrispondenti possono essere “accoppiati”

Ma… un’ampia sperimentazione è auspicabilewww.siderean.com/dc2003/Paper23-abstract.pdf

È un settore di ricerca al quale sono interessati enti culturali (musei, archivi). Ma gli sviluppi attuali riguardano molto l’e-learning

Esiste un protocollo (Open Archive Initiative Metadata Harvesting Protocol, OAI-MHP) che consente a sistemi in rete di comunicare condividendo risorse di metadati

I sistemi possono essere definiti come Repository e Harvester. Quest’ultimo effettua la richiesta, mentre il primo “espone” i dati richiesti

Strumenti per la cooperazione nell’apprendimento e costruttivismoStrumenti per la cooperazione nell’apprendimento e costruttivismo

Le Assunzioni del Costruttivismo

La conoscenza viene costruita a partire dall’esperienza

L’apprendimento è un’interpretazione personale del mondo

L’apprendimento è un processo attivo nel quale il significato è

sviluppato sulla base dell’esperienza

La costruzione dei concetti nasce dalla negoziazione dei

significati,dalla condivisione di prospettive multiple e dal cambiamento

delle nostre rappresentazioni interne attraverso l’apprendimento

collaborativo

L’apprendimento dovrebbe essere situato in contesti realistici; il

processo di valutazione dovrebbe essere integrato con gli obiettivi e

non essere considerato come attività a se stante

(Merrill, 1991, in Smorgansbord, 1997)

Digital Rights ManagementDigital Rights Management La gestione dei diritti digitali è un contesto complesso in rapida

evoluzione. Riguarda principalmente la protezione della

proprietà intellettuale dei contenuti digitali. Nella fase attuale, le

tecnologie di protezione hanno prodotto sistemi proprietari (es.

eBook e il Digital Asset Server di Microsoft)

Nei sistemi di rete (e dunque nei repository distribuiti) il

problema va risolto anche tecnologicamente, oltre che

giuridicamente, anche per le amministrazioni pubbliche

Alcuni approcci vanno nella direzione del “broker” per le parti

coinvolte (intermediazione dei diritti oltre il rapporto tra autore e

Content Provider). È la posizione del W3C, tra gli altri

Tali soluzioni eliminano la necessità di più contratti o account

ed evolvono dalla protezione all’amministrazione dei diritti

Proposals for the European TEL EnvironmentProposals for the European TEL Environment

Developing the European way to TEL Focusing on content validity and didactic strength Digitalizing the European culture for enriching the

knowledge base of European citizens through new IS technologies (electronically linking all the knowledge owners among them)

Enforcing and pushing the European TEL industry Creating a Global European Application Profile Bringing the European citizens to use e-learning as

a form of natural breadth (making it easier to develop and use…?)

Conclusions Conclusions

Move finally from machines to people

Take care about real learning needs: each project is a part in a more general framework

Organize and manage single projects strictly

Leverage TEL to the highest dignity, as a base for future economic development

Create the European vision: TEL is a component of our culture?
