O poprawności przewodników metodycznych do nauczania języka polskiego (normatywnie)

The article discusses some issues related to correctness (in the area of orthography, punctuation, inflections, vocabulary, phraseology, syntax and stylistics) of teaching guides including lesson plans for Polish. On the basis of a few randomly selected publications some most frequent mistakes in such type of guidance materials have been described, leading to the conclusion that mistakes in the publications meant to provide a helpful aid in teaching, especially their lack of clarity and ambiguities, do not only disrupt fluent reception and are evidence of the author’s lack of competence or the carelessness of the proofreader. They also cause the situation in which their recipient, the teacher of Polish, who encounters an inaccurately written text could have major difficulties in understanding the author’s intention. It may result in a need to plan the lesson independently, which makes the guide fail to fulfill its role.
