New Media and Online Mathematics Learning for Teachers

In this chapter we offer a case study of an online Mathematics for Teachers course through the lens of four affordances of new media: democratization, multimodality, collaboration and performance. Mathematics, perhaps more so than other school subjects, has traditionally been a subject that people do not talk about outside of classroom settings. However, we demonstrate through the case of the Mathematics for Teachers course that this does not have to be the case. Mathematics, even mathematics that traditionally has been seen as abstract or inaccessible, can be talked about in ways that can engage not only adults but also young children. The affordances of new media can help us rethink and disrupt our existing views of mathematics (for teachers and for students) and of how it might be taught and learned, by (1) blurring teacher/student distinctions and crossing hierarchical curriculum boundaries; (2) communicating mathematics in multimodal ways; (3) seeing mathematics as a collaborative enterprise; and (4) helping us learn how to relate good math stories to classmates and family when asked “What did you do in math today?

Management of clandestine drug laboratories: Need for evidence-based environmental health policies

Clandestine drug laboratories (CDLs) have been emerging and increasing as a public health problem in Australia, with methamphetamine being the dominant illegally manufactured drug. However, management and remediation of contaminated properties are still limited in terms of regulation and direction, especially in relation to public and environmental health practice. Therefore, this review provides an update on the hazards and health effects associated with CDLs, with a specific look at the management of these labs from an Australian perspective. Particularly, the paper attempts to describe the policy landscape for management of CDLs, and identifies current gaps and how further research may be utilised to advance understanding and management of CDLs and inform public health policies. The paper highlights a significant lack of evidence-based policies and guidelines to guide regulatory authority including environmental health officers in Australia. Only recently, the national Clandestine Drug Laboratory Guidelines were developed to assist relevant authority and specialists manage and carry out investigations and remediation of contaminated sites. However, only three states have developed state-based guidelines, some of which are inadequate to meet environmental health requirements. The review recommends well-needed inter-sectoral collaborations and further research to provide an evidence base for the development of robust policies and standard operating procedures for safe and effective environmental health management and remediation of CDLs. © 2013 The Japanese Society for Hygiene
