Describes research using a pedagogic strategy developed during an exploratory work called Active Graphing in which access to spreadsheets allows graphs to be used as analytic tools within practical experiments. Identifies aspects of student interaction with the experiment itself, the data collected and the graphs, and traces the emergence of…

Without using data to inform their actions at every step of the way, teachers and administrators will probably not reach their goals for school improvement. In this article, the authors describe a CRESST initiative that helps educators develop the skills to collect, analyze, and be guided by data. Five steps to effective date use are described in…

Research results should not be taken at face value; some research is not well designed, and readers must be able to assess whether the research carried out actually supports the results or may be explained otherwise. Research reports are usually divided into introduction or literature review, methods, results, and discussion and conclusions. Basic…
