In a laboratory setting, what strategy best aids ELLs' comprehension while receiving directions?

Demonstrating the use of equipment physically to illustrate instructions is highly effective for aiding English Language Learners (ELLs) in a laboratory setting. This approach offers several advantages that significantly enhance comprehension.

First, a physical demonstration allows ELLs to see the procedure in action, which bridges the gap between verbal instructions and practical application. Many students, particularly those who may struggle with language, benefit from visual and kinesthetic learning experiences. When students can observe the steps taken to use equipment or conduct experiments, they can better grasp complex concepts that might be challenging to understand through verbal explanations alone.

Moreover, physical demonstrations can engage multiple senses, reinforcing learning. As ELLs watch, they may also be able to touch or handle the equipment, further solidifying their understanding of how it operates. This hands-on experience can be invaluable, providing context and clarity that paper instructions or verbal lectures may not convey.

In this scenario, the preparation of experiments or pairing students with native English speakers, while beneficial in certain situations, may not directly address the immediate need for understanding instructions through direct interaction with the material. Writing key terms on the board can support literacy skills but may not provide the same depth of understanding as direct demonstration. Using physical demonstrations, therefore, stands out as
