Answer:
To achieve her goal Ms Castro should have students:
Practice using pre-taught sentences stems with simple structures and tensus during collaborative activities.
Step-by-step explanation:
There are three main reasons behind this strategy, the first one is that language is a social skill. So it has to be learned in a group, therefore practicing from role models has to be a must in language learning scenarios. Second, learning from pairs is better than learning from impaired individuals because they will have more affinity as well as opportunities to have fun while they learn. Third, English syntax is a very difficult topic, that language learners have to experience to develop a high level of the domain of a certain language. Therefore, it is recommended to learn from people that have just achieved that ability and have learnings to share with individuals learning it because it can guide with more ease. Unlike individuals with more time of having learned it, because for them it will be more natural, and explanation would be most difficult.
