Assessing transformative learning in teacher education

This paper formed one element of the roundtable presentation Service learning as community engagement: Exploration of academic staff skills for assessment of learning (with Avril Bellinger, University of Plymouth; Gail Goulet (University of Glasgow, Chair); Janet Strivens, University of Liverpool). It outlines some of the key issues in assessing transformation in student learning in a professional studies element of a teacher education course

Professional identity

This chapter discusses the concept of professional identity and how professional teachers develop their identity. Policy contexts as well as research contexts are discussed in terms of how these shape professional working conditions

High vacuum facility for hydrazine thruster testing

An ongoing modification is described of a large vacuum chamber to accommodate the ignition of an arcjet hydrazine thruster while maintaining a vacuum level of 1 x 10(exp -5) torr or less. The vacuum facility consists of a 20 ft stainless steel vacuum tank with an internal LN2 shroud, four 35 in. cryopumps and an 8 in. turbopump. To maintain a vacuum level of 1 x 10(exp -5) torr or less, 900 sq ft of liquid helium (LHe) shroud surface was installed to maintain the vacuum level and pumping requirements. A vacuum level of 1 x 10(exp -5) torr or less will allow the hydrazine thrust to exit the thruster nozzle and radiate into a space type environment so that the plume flow field can be analyzed and compared to the analytical model density distribution profile. Some other arcjet thruster characteristics measured are the electromagnetic interference (EMI) and exhaust contamination. This data is used to evaluate if the arcjet thruster with its high specific impulse in comparison to current chemical propulsion thruster can be used for the next generation of communication satellites
