Which Principles of Material Design are most important for you? Why?

I haven chosen the following Principles of Material Design:

1 Make sure the texts and tasks are as interesting, relevant and enjoyable as possible so as to exert a positive influence on the learners’ attitudes to the language and to the process of learning it.

3 Make use of activities which get learners to think and feel before during and after using the target language for communication.

I truly believe learners only get engaged in their own learning process if the materials we use are interesting and make sense to them. Students must see the content as something useful and meaningful.

I´m also an enthusiast of activities that use critical thinking, and, if the material can also provide awareness besides of formal learning, much better.
