摘要
教育研究常常遇到抽样的问题 ,而我们阐述较多的是如何使用随机抽样以保证教育研究的科学性。对使用较多的有目的抽样则阐述较少。本文以随机抽样的局限性为引子 ,集中对教育科研中有目的抽样的含义、变式、以及如何应用做了初步的探讨 。
Sampling is basic for education research. What we have set forth the most about sampling in education research, however, is random sampling to enhance the objectivity of the research. Little has been said about purpose sampling which is used much more in practice. In this paper, the author use random sampling as an introduction to explore mainly purpose sampling: its implication, its different pattern, and the way of how to use it. The aim of the paper is to draw the attention of researchers.
