title: Using apps for teaching and learning mathematics: A socio- technological assemblage

authors: Calder, Nigel Stuart

abstract: This paper reports on an aspect of a research project that examined the use of apps in primary school mathematics programmes. It reports teacher and student perspectives on how they used a range of digital tools within the apps to solve problems. We consider the interplay between the affordances of the mobile technologies, including multi- representation and haptic, with other social and pedagogical aspects, and how the assemblage of social and technological entities influences the ways that teachers might integrate apps into their mathematics programmes.

title: Synthesis and characterisation of four- and eight-membered ring auralactam complexes

authors: Henderson, William

subjects: Gold

abstract: The reactions of the cyclo-aurated gold(III) dihalide complex [{C6H3 (CH2NMe2)-2-(OMe)-5}AuCl2] with N-cyanoacetylurethane [NCCH2C(O)NHCO2Et], 2-benzoylacetanilide [PhC(O)CH2C(O)NHPh] and acetoacetanilide [MeC(O)CH2C(O)NHPh], and [{C6H4 (CH2NMe2)-2}AuCl2] with acetoacetanilide in dichloromethane with excess silver(I) oxide gives the first examples of auralactam complexes, containing Au-NR-C(O)-CHR′ four-membered rings. A single-crystal X-ray diffraction study on the complex [{C6H4 (CH2NMe2)-2}Au{NPhC(O)CH(COMe)}] reveals similar structural features to related metallalactam complexes of platinum(II) and palladium(II). When a CDCl3 solution of the complex [{C6H3 (CH2NMe2)-2-(OMe)-5}Au{N(CO2Et)C(O)CHCN}] is allowed to stand for 18 h, a novel dimerisation reaction occurs, giving the insoluble product [{C6H3 (CH2NMe2)-2-(OMe) 5}Au{N(CO2Et)C(O)CHCN}]2 2CDCl3, characterised by an X-ray structure determination. The dimer contains an eight-membered Au-N-C(O)-C-Au-N-C(O)-C ring.

title: "It's the controlling still". Power effects in the implementation of the bicultural/bilingual early childhood curriculum in Aotearoa/New Zealand.

authors: Ritchie, Jenny

subjects: racism

abstract: Racism is an undelying current within educational practice in Aotearoa/New Zealand. This paper discusses some of the data from a doctoral study that explored a particular teacher education context. In Aotearoa, the early childhood curriculum, Te Whariki, has a bicultural paradigm that requires a degree of bicultural and bilingual competence on the part of educators. This paper explores some of the issues around preparing teachers to deliver this curriculum, with a particular focus on racism.
