Application Research of Quasi-experimental Research in Educational Technology

论文首先介绍准实验研究中的多种实验方法，按照实验对象将其分成单组实验和多组实验，并使用案例分析法分析、介绍其在教育技术领域内的应用，接着论述了几种提高准实验研究效度的方法，最后，对准实验研究在教育技术领域中的应用进行了总结。

Firstly the paper reviews some kinds of experimental methods in quasi-experimental research， divides them into single-group experiment and multi-group experiment according to the group numbers in the experiment. Then the paper introduces the application of the quasi-experiment in educational technology with some cases. Followed by introduce some methods to improve the experiment validity of quasi-experimental research. Finally， the paper summarizes the application of the quasi-experimental research in educational technology.
