Action Research in the classroom: Thinking about different kinds of evidence to measure impact

This article suggests how teachers could embark upon collecting data for action research (AR) projects related to science teaching. Previous articles (EiS, May & Nov 2015) provided an overview of some of the issues useful for teachers to consider before embarking on data or evidence collection in their classroom or school. This follow-on article develops some ideas further by outlining diverse kinds of data that could be collected. Before gathering any evidence for a research study, however, it is important that would-be researchers gain ethical approval (and permission from participants and headteachers) to ensure that the research process and outcomes do not distress or disadvantage those involved in any way (see https://www.bera.ac.uk/).
