The philosophy of the approach to teaching, learning and development can best be described as a new new-materialistic approach influenced by present thoughts on posthumanism.
Posthumanism means going beyond the human as the sole focus of attention. When it comes to teaching and learning, it means, that rather than focussing on the human learner or the teacher per se, the focus of attention is on the apparatus of the whole situation through which the process of learning as a material-discursive practice is taking place and through which the human become aswell. It means including a wide variety of influential forces, that are typically not considered part of learning.
In other words - the focus is on 'who and what is doing the teaching' and 'who and what is making the learning happen'.
Thus focus is on including not only the most obvious factors (the teacher, teaching plan, powerpoints, blackboard-notes, handsouts, curriculum and students engagement).
Also various kinds of other, perhaps more subtle, yet determining factors. For example the interior decor of the setting (materials, colors, sitting/standing arrangements, etc), the room temperature, blood-sucker levels among the human participants, the time of the day, time of semester, etc. are also determining factors to be included if we are to acknowledge the present paradigmatic turns,
In sum, we are to acknowledge that learning happens through the apparatus of the whole situation. What the portfolio refers to as the learning-scenography.
