Teachers Learning Mathematics: Professional development research
Introduction The issue of mathematical knowledge of teachers has been documented in New Zealand for 80 years, but no effective long-term solution has been found; indeed, the situation has worsened. For example, the 2004 New Zealand Ministry of Education Teacher Census (Ministry of Education, 2005) showed that 25 percent of secondary school mathematics teachers had no university mathematics qualification—a rise from 21 percent in 1977. This one-year research study, undertaken in 2007, aimed to investigate the development of teachers’ own mathematical knowledge for teaching. Seven secondary teachers used action research methodology to investigate, develop and evaluate some aspect of their mathematical knowledge, completing two cycles over the year. In addition, the
