Kao asserts that these prepositions are hard to learn and usually take quite a long time to learn because learners need to rely heavily on their memorization and storage. Kao’s study (2001) suggests that formal instruction could improve learners’ performance of these language features.
Due to the nature of pseudo-prepositions as mentioned above, teachers often find it hard to introduce these prepositions to ESL/EFL learners. No rules can be stated, nor will explicit instruction fulfill the learners’ needs and help them to acquire these prepositions. For this reason, providing the learners with a great number of enhanced instances of prepositional uses to allow the learners to get as much exposure to the target features as possible may help draw the learners’ attention to these features (Kao, 2001). Furthermore, encouraging students to notice these linguistic features and raising their consciousness of the existence of these features may help strengthen their learning. This research was then conducted to investigate the effects of input
