Two tests (pre-test and post-test) were utilized to gather the research data. Both tests are Grammaticality Judgement Test (GJT). In applied linguistics literature, GJT is well-known as a “standard method of determining whether a construction is well-formed” (Rimmer, 2006, p. 246). Researchers have been using GJT since the 1970s to assess the learners’ language proficiency and knowledge of grammar (Tan & Noor Izzati, 2015). As the research aim is to measure the grammar accuracy of the participants prior to and after the treatment, the instrument is deemed appropriate for the research. Each test is composed of twenty-five items sectioned into two parts. Part I incorporated twelve items (eight incorrect and four correct sentences). Participants were asked to judge the grammaticality of each one. In part II, however, students were asked to answer thirteen multiple-choice cloze questions. The test covered selected grammatical points including adjectives, adverbs, articles, nouns, pronouns, and verb tenses. These points were presented in different cases affirmative, negative ad interrogative. The items were adapted from Swan and Baker’s (2008) Grammar Scan Test.
