Mass media and environmental knowledge of secondary school students in Hong Kong

A postal survey on a random cluster sample of 1032 secondary school students in Hong Kong was conducted to investigate what and how much students know about the environment and how their knowledge is related to use of mass media. Results indicated that students were very knowledgeable on general and local environmental issues. The average score for environmental knowledge was 60.7 on a 100-point scale. There was some indications that students' environmental knowledge was shaped and limited by the reporting of environmental news in Hong Kong. Television news viewership had positive correlation with students' environmental knowledge while Chinese newspaper readership had a positive but weak correlation. Male students and students in higher forms were more knowledgeable about the environment. The study established a comprehensive measure for both general and local environmental knowledge with an acceptable level of internal consistency for subsequent studies.
