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.

Previous studies have associated L2 teachers' use of motivational strategies with learners' motivated behaviours in class such as raised attention and participation. The after-class effects of L2 motivational strategies, in contrast, have drawn less attention. This paper reports a study examining how L2 teachers' motivational interventions cause changes in learners' perceived attitudes and behaviours, both within and beyond the L2 classroom. To this end, 84 reflective journals were collected over one semester from 42 tertiary students in Hong Kong enrolled in a range of English courses. The results indicate that reported increases in the use of additional self-learning materials, attempts to put newly acquired English knowledge into practice, efforts to reduce mistakes, and in-class engagement were attributable to L2 teachers' motivational efforts. This provides evidence that the benefits brought by L2 teachers' motivational practice can transcend the classroom. Copyright ©Routledge.
