A mail survey of 790 parochial school teachers and 350 public elementary school teachers in San Francisco (California) and two adjacent counties was conducted in the 1987-88 school year to ascertain the teachers': perceptions of media use by students; use of media in the classroom; and educational goals for their students with regard to media. A total of 373 questionnaires was returned for a response rate of 33%. Among the respondents, 198 were considered media active and 175 were counted as "less active". The respondents generally had 5 or fewer years of teaching experience; they were less experienced and generally younger than the average teacher in their school systems. Teachers rated television as the medium most used by students, followed at a great distance by video/computer games, movies, and radio. Teachers were most likely to use personal computers as media in the classroom. Over two-thirds of the teachers considered that students spent too much time using media. Teachers generally considered students quite competent in the operation of most consumer-oriented media equipment, but considerably less than competent in media understanding skills. About two-thirds of teachers reported teaching about media as part of another subject. Between 25% and 33% of the respondents had discussed the role of media in society or the role of advertising with their students. Most of the teachers (86.6%) would have liked to teach about the media more often, but barriers included lack of time and lack of materials. The results highlight the need for more and improved media education materials. Survey results are presented in 21 tables. The survey instrument is included. (SLD)
