A survey involves students in direct observation and data collection. For example, students record information, such as how many classmates turn the water off and on as needed when they wash their hands. An opinionnaire is similar to a questionnaire but attempts to measure opinions or beliefs of human beings concerning specific topics. Discuss the writing of research questions. Guide the groups in the development of the research tool selected.
Larger samples equal better data.
Act as a resource for students as they draw conclusions and make recommendations based on the data. I am a student at Hometown School. One of my classes is researching water conservation actions. The possible questions are unlimited. The length of student questionnaires will be determined by the amount of information sought.
