The Polish Vocabulary Size Test: A Novel Adaptive Test for Receptive Vocabulary Assessment
This provides a novel tool for vocabulary assessment in Polish, addressing a gap for both native and non-native speakers, but it is incremental as it applies existing adaptive testing methods to a new language.
The authors tackled the problem of assessing receptive vocabulary size in Polish by developing the Polish Vocabulary Size Test (PVST), an adaptive tool based on Item Response Theory and Computerized Adaptive Testing, which was validated in a pilot study with 1,475 participants showing that native speakers had significantly larger vocabularies and vocabulary size correlated with age.
We present the Polish Vocabulary Size Test (PVST), a novel tool for assessing the receptive vocabulary size of both native and non-native Polish speakers. Based on Item Response Theory and Computerized Adaptive Testing, PVST dynamically adjusts to each test-taker's proficiency level, ensuring high accuracy while keeping the test duration short. To validate the test, a pilot study was conducted with 1.475 participants. Native Polish speakers demonstrated significantly larger vocabularies compared to non-native speakers. For native speakers, vocabulary size showed a strong positive correlation with age. The PVST is available online at myvocab.info/pl.
