Long Ago and Far Away: Preservice Teachers’ (Mis)Conceptions Surrounding Racism

THE IMF LONG AGO AND FAR AWAY: Faint Stars in the Ursa Minor dSph Galaxy

The dwarf spheroidal galaxy in Ursa Minor is apparently dark-matter dominated, and is of very low surface brightness, with total luminosity only equal to that of a globular cluster. Indeed its dominant stellar population is old and metal-poor, very similar to that of a classical halo globular cluster in the Milky Way Galaxy. However, the environment in which its stars formed was clearly differe...

Using Concept Maps to Assess and Categorize Elementary Preservice Teachers Misconceptions

This research study reports on the use of concept maps as an assessment tool to investigate elementary pre-service teacher knowledge about dissolving. Propositions from pre/post concept maps were scored using the total proposition accuracy scoring technique (TPA) and were also used to classify concepts as scientific or spontaneous using Vygotsky’s theory of concept development. Vygotsky (1986) ...

These behaviors, which can occur alone or in combination, sporadically or continually, include physical violence, psychological abuse, talking, and nonconsensual sexual behavior.

Preservice Primary School Teachers’ Elementary Geometry Knowledge

Geometrical notions and properties occur in real-world problems, thus Geometry has an important place in school Mathematics curricula. Primary school curricula lays the foundation of Geometry knowledge, pupils learn Geometry notions and properties by exploring their environment. Thus it is very important that primary school teachers have a good base in elementary Geometry. The aim of this paper...
