Prescriptive grammar rules are taught in education, generally to ban the use of certain frequently encountered constructions in everyday language. This may lead to hypercorrection, meaning that the prescribed form in one construction is extended to another one in which it is in fact prohibited by prescriptive grammar. We discuss two such cases in Dutch: the hypercorrect use of the comparative particle dan ‘than’ in equative constructions, and the hypercorrect use of the accusative pronoun hen ‘them’ for a dative object. In two experiments, high school students of three educational levels were tested on their use of these hypercorrect forms (nexp1 = 162, nexp2 = 159). Our results indicate an overall large amount of hypercorrection across all levels of education, including pre-university level students who otherwise perform better in constructions targeted by prescriptive grammar rules. We conclude that while teaching prescriptive grammar rules to high school students seems to increase their use of correct forms in certain constructions, this comes at a cost of hypercorrection in others.

过度矫正作为教育的副产品

在教育中教授规定的语法规则，通常是为了禁止在日常语言中使用某些经常遇到的结构。这可能会导致过度修正，这意味着将一种结构中的规定形式扩展到另一种结构，而实际上规定语法禁止了另一种结构。我们在荷兰语中讨论了两个这样的情况：在等式结构中比较级助词 dan 'than' 的超正确使用，以及宾格代词 hen 'them' 对与格对象的超正确使用。在两个实验中，三个教育水平的高中生测试了他们对这些超正确形式（nexp1 = 162，nexp2 = 159）的使用。我们的结果表明，所有教育层次都存在大量的过度矫正，包括大学预科水平的学生，否则他们在规定语法规则的目标结构中表现更好。我们得出的结论是，虽然向高中生教授规定的语法规则似乎会增加他们在某些结构中正确形式的使用，但在其他结构中却以过度纠正为代价。
