Massive Open Online Courses in the Initial Training of Social Science Teachers: Experiences, Methodological Conceptions, and Technological Use for Sustainable Development
Abstract
:1. Introduction
Massive Open Online Courses and Education for Sustainable Development
- -
- What is the perception of future teachers (digital natives) of their digital teaching competence (DTC)?
- -
- What factors determine the social representations of the potential contribution of ICTs in general, and of MOOCs in particular, to the teaching and learning of sustainable development goals (SDGs)?
- -
- Do these representations appear to be determined by gender and education?
2. Objectives
- -
- Determine and describe the level of DTC in the participating students, as well as their perceived utility of ICTs for their teaching.
- -
- Analyze students’ appraisal of the importance of reducing the “digital divide”, and the role of ICTs and MOOCs in the convergence of communication and development on a global level.
- -
- Observe the behavior of the data and results obtained, based on the participants’ gender and teacher training.
