Which of the following is an example of a formative assessment suitable for ELLs?

A formative assessment is designed to monitor student learning and provide ongoing feedback that can be used by instructors to improve their teaching and by students to enhance their learning. The correct choice involves interactive strategies that encourage active participation and provide immediate opportunities for feedback.

Think-pair-share activities are particularly effective for English Language Learners (ELLs) because they allow students to articulate their thoughts through discussion. This method not only helps ELLs practice their language skills in a low-pressure environment, but it also promotes collaboration and deeper understanding as they share their ideas with peers.

The other options do not align with the principles of formative assessment. Standardized tests and end-of-term exams are typically summative assessments that measure what students have learned at the end of a period, rather than providing real-time feedback. Group projects that do not require verbal participation limit opportunities for language development and do not facilitate the kind of peer interaction that is beneficial for ELLs. Therefore, choice C stands out as the most suitable formative assessment method for this context.
