Motivation

Teaching-Learning process

Learnercentered approach

Learning by Viewing Learning by Doing

Sweller and Cooper (1985)

Educational Resources

E-learning Tools

Student-centered

Combination of paradigms: learning by viewing vs. by doing

Educational resources: available and diversified

E-Learning tools: ubiquitous and interoperable


Motivation

Ensemble framework

Conceptual tool for networks of e-learning services in domainswith complex evaluationSpecialization in the Computer Programming domainValidation at ESEIG (an IPP school)

Motivation

Sequencing standards

Resources sequencing in learning environments

Criticisms

Modularization - included in Learning Objects (IMS CP)Scope - widen excessively the scope (”spray and pray”)Utility - more focused on quantity (”shovelware”)Complexity - difficult to implement

Example: IMS (Simple) Sequencing


Motivation

Tools integration standards

Ad hoc solutionsProprietary plugins (Moodle Repository API)Focus on interoperability: IMS Learning Tools Interoperability

Architecture


SeqinsData model

Entities

Student

Identification (LTI context variables)State: last resource consulted (or solved) and date

Course

Organized in units (or modules)Each unit contains a set of resourcesEach resource contains an URL and an weight

SeqinsSequencing model

Simple sequencing model

Weights associated with the evaluation resources of an unit

Sequential visualization and resolution within an unit

To obtain success in an unit U’∑U′lengthi=1 wRi ∈ U ′ ≥ mwU ′

Competitive facet

Success to a unit unlocks access to the next unit”A la” computer games


Ensemble integration

Seqins integration in an Ensemble instance

Apply Seqins in the field of computer programming

Integration at two levels:

1 Communication

2 Data



1. Communication

Based on LTI 1.1 specification

REST as the web service flavour

Bidirectional communication

LTI functions:



1. CommunicationData sent by Tool Consumer (LMS/Seqins)

Course/Activity (id, title, description)Student (id, name, email)Other data (OAuth, dates, etc.)
