AWA: Academic Writing at Auckland

A Research Methods Report helps the writer learn the experimental procedures and the ways research findings are made in that discipline (Nesi & Gardner, 2012, p. 153). The question to be investigated is often provided as part of the assignment, and there is usually less focus on existing research and much more on the methods and results of the writer's own research. An IMRD (Introduction, Methods, Results, Discussion) structure is often used. AWA Research Methods Reports include Experiment Reports, Field Reports and Lab Reports.

Abstract for research proposal on Obsidian Hydration Bands dating technique

Abstract for Research Proposal

Radiocarbon dating of archaeological sites in New Zealand is hindered by the presence of a large ‘wiggle’ in the calibration curve during the timeframe within which New Zealand’s prehistory occurs. As such costly radiocarbon dates can often return results with large ranges of error. Obsidian hydration dating (OHD) has been proposed as an alternative due to the extensive use of obsidian in most sites within the country and lower cost, however it has suffered from inaccuracies due to technological constraints. New technology made available has reduced errors in OHD prompting research into its potential elsewhere in the world. This research will look to establish its usefulness in a New Zealand context by collecting obsidian flakes from different sources and sites throughout the country and analysing their hydration using Secondary Ion Mass Spectrometry (SIMS). Dates obtained by this method will then be compared using statistical tests against secure radiocarbon dates for the sites. If effective it may lead to the adoption of OHD as the norm for site dating in New Zealand and establishment of a database of OHD data for use in all regions across the country reducing the costs of accurately dating prehistoric sites.
