The increase in international cooperation for the benefit of science education is noted. The foreign lecturer program in the physical sciences for the 1960 summer institutes for science and mathematics teachers, supported by the National Science Foundation, is described. This program included seven physicists, five chemists, two astronomers, one meteorologist, and one geophysicist. A report of the briefing and evaluation conferences is followed by an introduction to the six physics papers. Three of these are in solid-state physics. There is one each in nuclear physics, radio astronomy, and cosmic rays. Results of a questionnaire to determine the usefulness, among high school teachers, of last year's special March issue are also reported.
