In modern composition courses, academic writing is often used as another form of testing. Similarly, in many English as a second or foreign language (ESL/EFL) learning contexts, writing lessons are structured with a test orientation aimed at achieving “native-like proficiency” (McKay, 2009, p. 39). This situation leads to the reality that ESL/EFL students' writings focused more on language use instead of creating spaces for certain groups of writers to express their thoughts in English. Therefore, many ESL/EFL writers face anxiety about writing in English. On the other hand, the paradigmatic thinking and expository writing widely used in ESL/EFL writing classes do not give students the opportunity to write about what they are interested in. As a result, these types of tasks reduce students' motivation to write in English. write. To allow students to have freedom and say in their writing, many researchers have worked on the concepts of free writing and cross-genre writing to motivate students to rediscover the joy of writing. In this essay, I first aim to discuss how students can benefit from multi-genre and free-writing tasks; and describe my design of a writing activity – “Message in a Bottle”; elaborates what skills ESL/EFL students can master through this activity and the changes in their attitude towards English writing. Multi-genre writing and free writing To better understand the meaning of multi-genre writing, it is necessary to note that writing itself is socially and culturally constructed. Learning from Romano (1995, 2000), I understood that writing should not be limited to one form but remain open to the changes and differences found in the middle of the page......it is preferred in writing. Therefore, by using this activity, ESL/EFL students can be more expressive in English writing. Discussing the benefits of multi-genre writing and free writing in relation to the context of teaching ESL/EFL composition in the classroom, I believe that designing the writing activity that combines the characteristics of these two writing pedagogies in teaching writing to students ESL/EFL, reducing their anxiety in writing in a second language, building their confidence in writing and allowing them the freedom to express their inner thoughts. Although the “Message in a Bottle” assignment may have some limitations in that students may not be able to send their messages into the ocean, the assignment itself still involves many topics that could inspire ESL/EFL students in lessons of composition be more active in the practice of writing in English.
