Hidden measurement model for pure and mixed states of quantum physics in Euclidean space

We propose a representation of quantum mechanics where all pure and mixed states of a n-dimensional quantum entity are represented as points of a subset of an ²-dimensional real space. We introduce the general measurements of quantum mechanics on this entity, determined by sets of mutual orthogonal points of the representation space. Within this framework we construct a hidden measurement model for an arbitrary finite dimensional quantum entity.     

Australian teachers’ views of effective mathematics teaching and learning

Thirteen Australian teachers who had been nominated by their professional mathematics teachers’ associations as excellent teachers of elementary school mathematics were interviewed on their beliefs about mathematics, mathematics learning and mathematics teaching. In particular, they were asked to discuss the characteristics of effective teachers of mathematics and excellent mathematics lessons. In spite of their differences in location, experience and teacher education, the teachers displayed a lot of consistency in their responses and in their lists of characteristics. While this group of teachers cannot be claimed to be representative of Australian teachers, they have provided a snapshot of what is regarded as effectiveness in mathematics education in Australian elementary schools.
