Post-truthism entered mainstream consciousness after being named "Oxford Dictionary's" word of the year in 2016, denoting a turn in the Western relationship with truth as a certain and indisputable object. Simultaneously, and paradoxically, rising distrust around teachers' professional judgement and a desire for certainty in practice saw…

This article reports and compares results from an interview study of early childhood teachers in the U.S. and Hong Kong, with a focus on the math outcomes that children may gain from play with unit blocks. Teachers were interviewed to obtain their ideas of the benefits of unit block play in three focal areas: geometry, measurement, and numeracy.…

In 2015, a new Master of Teaching coursework unit, Numeracy for Learners and Teachers, was introduced at Monash University in Melbourne, Australia. The drivers for the establishment of the unit were the Australian Institute for Teaching and School Leadership numeracy standards for graduate teachers and the inclusion of numeracy as a general…

In this article, I present an initial analysis of an empirical study that was undertaken in an attempt to elicit what subject-matter knowledge, pedagogic content knowledge and curriculum knowledge teachers bring to bear on decisions for teaching. The analysis is based on interview data with 46 Grade 3 teachers, who were presented with two…

If teachers are to adequately support development of their students' numeracy capabilities then they need to have an identity as a teacher of numeracy. A preliminary evaluation of a conceptual framework (Bennison & Goos, 2013) developed for use in a two-year study that seeks to understand this construct is presented. Initial findings about an…

It is essential that pre-service teacher educators address pre-service teacher numeracy but with careful consideration as it incorporates more than mathematics skills. Numeracy also involves disposition towards mathematics--attitudes, confidence and mathematics anxiety; that is, the level of willingness to use mathematics skills. As part of an…

The goal of this study was to investigate understanding of in-service elementary school teachers in Taiwan about number sense, teaching strategies of number sense and the development of number sense of students. Data were gathered through interviews of nine elementary mathematics teachers, regarding their understanding about number sense. The data…

This paper reports on the evaluation of a six-day programme that provided professional learning to middle school teachers with the aim of equipping them to assist their pupils to achieve improved numeracy outcomes. A teacher profiling instrument designed to measure varied aspects of teachers' knowledge for teaching mathematics was administered to…

This is a record of the proceedings of the 30th annual conference of the Mathematics Education Research Group of Australasia (MERGA). The theme of the conference is "Mathematics: Essential research, essential practice." The theme draws attention to the importance of developing and maintaining links between research and practice and…
