In the last two decades, the same three parameters (frequency of use, importance, and effectiveness) of motivational strategies in language classrooms have been thoroughly researched. This study proposes establishing an additional parameter of feasibility to gauge the overall ease of using motivational strategies. A questionnaire survey on 116 motivational strategies was conducted among 58 Hong Kong teachers of English as a foreign language (EFL). After that, 20 of them participated in focused group interviews to provide further comments. Nine feasibility-related factors pertinent to students, the teacher, and the educational context were identified, which contribute to a tentative and concise definition. • Certain parameters of motivational strategies have been widely researched. • A new parameter of feasibility in language teaching contexts is called for. • Student-, teacher- and context-specific factors were identified by English teachers. • A concise definition of the new feasibility parameter is proposed. • The feasibility parameter is noticeably different from the effectiveness one.
