Opis:
While it is a well-known fact that speakers of article-less mother tongues, such as Polish, experience problems with articles in English, this study seeks to investigate the problem from a different perspective. Namely, it poses the question of whether the correct use of the article system of the L2 is indeed a purely grammatical task (as it is universally perceived), or whether the correct use of articles is to some extent aided by the mechanisms that underlie the formulaic character of language. The study was conducted with 90 Polish upper-intermediate and advanced users of L2 English, who completed a test on article use, which made it possible to compare patterns of article use between contexts of different collocational strength (defined in terms of the frequency of occurrence in a corpus). The statistically higher success rates for article use in high-frequency collocations (with the grammatical “rule” being the same) indicate that phraseological aspects of language use may indeed play a role in what is usually perceived as the correct application of grammatical rules.

Opis:
Researchers are frequently confronted with unanswered questions or items on their questionnaires and tests, due to factors such as item difficulty, lack of testing time, or participant distraction. This paper first presents results from a poll confirming previous claims (Rietveld & van Hout, 2006; Schafer & Gra- ham, 2002) that data replacement and deletion methods are common in research. Language researchers declared that when faced with missing answers of the yes/no type (that translate into zero or one in data tables), the three most common solutions they adopt are to exclude the participant’s data from the analyses, to leave the square empty, or to fill in with zero, as for an incorrect answer. This study then examines the impact on Cronbach’s α of five types of data insertion, using simulated and actual data with various numbers of participants and missing percentages. Our analyses indicate that the three most common methods we identified among language researchers are the ones with the greatest impact  n Cronbach's α coefficients; in other words, they are the least desirable solutions to the missing data problem. On the basis of our results, we make recommendations for language researchers concerning the best way to deal with missing data. Given that none of the most common simple methods works properly, we suggest that the missing data be replaced either by the item’s mean or by the participants’ overall mean to provide a better, more accurate image of the instrument’s internal consistency.
