Correct Response: A. Providing the English learner with an individualized rubric addressing her most frequent errors is an appropriate differentiated support in this situation. Having a checklist will enable the English learner to find and fix her own errors, which leads to self-correcting and eventually eliminating those errors in the future. B is incorrect because, while a glossary of grammatical terms with examples is a good resource, it is not focused enough on the English learner's specific errors to address her individual needs. C is incorrect because having a high-achieving classmate work on editing the English learner's writing puts the responsibility for monitoring on the classmate, whereas with an individualized rubric the English learner can learn self-monitoring, thus building a sense of agency, independence, and empowerment.. D is incorrect because, in this scenario, the errors that the English learner makes are common for that student's language-proficiency level and first language. There is no evidence in the scenario that the entire class needs mini-lessons on Standard English grammatical conventions and rules.
