Do data collection methods matter for self-reported L2 individual differences questionnaires? In-person vs crowdsourced data.
Crowdsourcing offers great advantages in data collection by enabling researchers to recruit a large number of participants across geographical boundaries within a short period of time. Despite the benefits of crowdsourcing, no study has explored its valid
Author/Lead: Ruirui Jia, Ekaterina SudinaWe recruited a total of 209 in-person and 209 crowdsourced participants for comparison. Both groups completed the short versions of the Foreign Language Classroom Anxiety Scale and the Foreign Language Enjoyment Scale, provided their demographic and language learning background information, and completed the LexTALE test. Measurement invariance testing revealed that most (sub)constructs exhibited partial or full invariance, indicating stability in the measurement systems across both data collection settings. However, crowdsourced participants reported higher enjoyment and lower anxiety than in-person participants. These differences can be attributed to the more relaxed mental state of the crowdsourced participants who completed the survey outside of the classroom.
