摘要

化学教育研究人员经常遇到的一个问题，也是化学教育研究与实践(CERP)文章的审稿人经常提出的问题，即研究数据样本量(N)是否足够大?然而，这个问题的答案比简单的“是”或“否”要复杂得多!事实上，在研究文献中有大量关于这个问题的讨论，这使得研究人员更难做出决定。

Considerations of sample size in chemistry education research: numbers do count but context matters more!

A question which often arises for chemistry education researchers, and is also frequently raised by reviewers of Chemistry Education Research and Practice (CERP) articles, is whether a research data sample size (N) is big enough? However, the answer to this question is more complicated than a simple ‘yes’ or ‘no’! In fact, there is substantial discussion of this issue within research literature which can make it even harder for a researcher to decide.
