Let me assume that the General Science teachers of the state have been well prepared for their work and that at the present time they are more or less efficient teachers. Still there is the ever present task of keeping up with the curricular and learning studies that are going on in the field of General Science. New texts are appearing, yearly, new studies on content and methods seem to be on the increase and it takes rather nimble stepping on the part of the teacher to keep pace.
