1.Introduction

  • Open Distance Learning(ODL)

  • Socrates Minerva Project 87574-CP-1-2000-1-RO-Minerva-ODL

    • learner-centered

    • problem-based

    • creative learning

  • Expected results

    • eLearning systems more efficient, affordable and

    • user-friendly, while maintaining high scientific and

    • pedagogical quality


2.Course Structure

  • AdaptiveCourse Structure

  • Main Tools:

    • Learner’s Profile Eliciting Tool (LPET)

    • Automatic Tutoring Tool (ATT)

  • Purpose:

    • develop different learning strategies(depending on their objectives, preferences)

    • way of navigation through the learning material

  • Requires:

    • multi-level structure of a course


3.CustomizedPersonal Tutoring

  • Student profile

    • the student objectives statement

    • the specific way of navigating through the learning material

    • the scores of the tests and the structure of the correct/wrong answers

    • the input from the tutor

    • the contributions of the student in formulating new questions

  • and quizes, in proposing relevant support material and literature

    • the interaction between the students


4.Current Implementation Features

  • Login / Registration Unit

  • Choosing Objectives

  • Auto Testing & Formulating a Question

  • Database Structure

  • Technical Specifications


4.Current Implementation Features

4.1.Login / Registration Unit

Provides login for the already registered users, and a sign-in for the new ones

The user’s email is verified by sending the new user an activation code(in order to avoid abuse )


4.Current Implementation Features

4.2.Choosing Objectives

  • Gives learner’s the possibility to choose his / her objectives

    • master degree enrollment

    • simple course

    • a problem oriented study


4.Current Implementation Features

4.3.Auto Testing & Formulating a Question

  • Allows the students to evaluate their progress through the course

  • Users can formulate a question and post it

  • for validation from the tutor


4.Current Implementation Features

4.4.Database General Considerations

  • We consider for this project 2 types of databases:

    • “Socrates” database that is used to hold the

    • common data for the entire project

    • A database for each course, containing all the

    • information about the course


4.Current Implementation Features

4.4.Database Structure – “Socrates”

  • Socrates database holds information about:

    • courses

    • the users

    • objectives of each user

    • personal data of the users

Example of database tables


4.Current Implementation Features

4.4.Database Structure – course databases

  • The course database holds

  • the structure of the course

  • the questions and answers related to the chapters,

  • subchapters and paragraphs of the course and to

  • the keywords of the course,

  • each learner’s path through the course and the path suggested

  • by the LPET

  • users performances during the tests

The information from the database is used to dinamically generate the navigation menu of the course.
