Reliability refers to the internal consistency of learning materials and the dependability of contents and methods, thereby facilitating the implementation of the teaching/learning process.

  • Internal coherence: Are the materials well constructed with a consistent inter-relationship between the parts?

  • Methodological integrity: Do the materials reflect validated methodological premises in the selection of activities, exercises etc.?

  • Factual integrity: Do the materials present accurate information, examples and statements and authentic social behaviour?
