A State-Wide Earth Science Institute in Missouri

One-hundred-fifteen secondary school science teachers in Missouri were trained in 1969-70 in an NSF-funded, state-wide institute in which eight colleges and universities participated. An inquiry approach to teaching and learning, in contrast to lecturing and reciting, was to be used by the newly trained teachers. Because of this, special attention was given, during the training period, to teacher attitudes and attitude change in relation to students and classroom situations. Evaluation showed that the greatest positive change in teacher attitude came during the early, very intensive part of the year-long program.
