title: Enabling or limiting: the role of pre-packaged curriculum resources in shaping teacher learning

authors: Petrie, Kirsten Culhane

subjects: physical education

abstract: Pre-packaged curriculum resources that are purportedly designed to support teachers to deliver physical education in primary school settings have become prolific internationally. While both teachers and teacher educators use curriculum resources extensively, there has been little exploration into the effectiveness of resources in supporting teacher learning. The use of curriculum resources in one PD programme is used to illustrate the extent to which resources mediate teacher learning, acting as enablers and limiters for changing teacher practice, potentially both reskilling and deskilling teachers. The design and use of curriculum materials needs to be re-imagined in order to better support teacher learning.

title: Speed control with low armature loss for very small sensorless brushed DC motors

authors: Scott, Jonathan B.

subjects: DC motor drives

abstract: A method for speed control of brushed dc motors is presented. It is particularly applicable to motors with armatures of less than 1 cm3. Motors with very small armatures are difficult to control using the usual pulsewidth-modulation (PWM) approach and are apt to overheat if so driven. The technique regulates speed via the back electromotive force but does not require current-discontinuous drives. Armature heating in small motors under PWM drive is explained and quantified. The method is verified through simulation and measurement. Control is improved, and armature losses are minimized. The method can expect to find application in miniature mechatronic equipment.

title: From mainstream to manaaki: Indigenising our approach to immigration

authors: Kukutai, Tahu

abstract: In recent years, discontent with migration and migrants in the wealthy global north has manifested in disturbing ways: cue Brexit, xenophobia, border paranoia, far-right nationalism and its bedfellow white supremacy. On the surface, Aotearoa New Zealand appears to have escaped the uglier aspects of this nativism. Despite the grumblings of the New Zealand First Party, no serious popular or political anti-immigration movement has appeared, and racially motivated attacks against migrants are relatively rare. This is despite the fact that Aotearoa has a much higher relative foreign-born population share than the United States or United Kingdom,1 and ‘superdiverse’ Auckland – which comprises at least 40 per cent migrants – now has the ignominious claim to being the fourthleast affordable city in the world, far outstripping London and New York.
