Developing a questionnaire to investigate second language learners’ preferences for two types of form-focused instruction

In this paper, we report on the process of developing and validating a questionnaire to explore second language learners’ preferences for two types of form-focused instruction (FFI): isolated and integrated FFI. Three types of evidence regarding the validity of the questionnaire were collected: content, reliability and construct. Content validity was obtained from expert judges and Cronbach’s alpha was used to measure the internal consistency reliability of the isolated and integrated FFI scales. A principal components analysis was used to assess the construct validity of isolated and integrated FFI. The results indicated that the questionnaire was both a valid and reliable measure of isolated and integrated FFI. We conclude by discussing some of the ways in which the questionnaire has evolved since its use in this study, how it has been used in related research and plans for its implementation in future studies.
