Data from the interviews with teachers were analyzed
using an approach recommended by Bogden and Biklen
(2003) to identify thematic content. To improve the credibility
of our interpretations of the data, three authors shared
in the process of developing, organizing, and validating
themes. Data were analyzed in two stages. First, interviews
were analyzed individually to identify key themes; second,
themes were successively compared, compiled, and reorganized
across interviews.
