Teachers in the 21st century need digital literacy skills to be effective, including the ability to access and evaluate information, use and manage information, and understand ethical and legal issues related to information access and use. Some challenges for teachers without digital literacy are that they may be less informed, skeptical of technology, and miss opportunities to engage with students. Standards like ISTE can help teachers develop these skills and provide expectations for how to design learning experiences and engage students using technology, while also promoting safe, legal, and ethical technology use among students. Technology should be used as a tool to advance student learning when combined with other skills, not as an end in itself.
