The document discusses how technology can aid English language learners (ELLs) in three main ways. First, tools like scanners, digital cameras, and video recorders allow ELL students to see visual examples to better understand assignments in math, science, and other subjects. Second, technology enables communication and collaboration through video chatting, online research, and question/answer forums. Third, productivity programs, databases, and spreadsheets provide multilingual interfaces and functions to help ELL students complete assignments and practice language skills. The document also provides several examples of software, websites, and lesson plans that teachers can use to incorporate these technologies into their ELL instruction.
