This document discusses how web tools can help support English language learners (ELLs) in core content instruction. It notes that ELL instruction should be linguistically accommodated and focus on listening, speaking, reading and writing skills across all content areas. Web tools allow for the creation of authentic opportunities for ELLs to practice their English skills through activities like listening, speaking, reading and writing. Examples of specific web tools that can be used for each skill are provided, such as VoiceThread for listening and speaking or PBWorks for reading and writing collaboratively. The goal is to use these tools to create a meaningful learning environment where ELLs can practice real communication.
