QR codes are two-dimensional barcodes that can be scanned by smartphones to access information online. They store data in a grid pattern and can be used to link to websites, apps, contact information, and more.
These are many options for free QR code generators. I suggest using this one:
Log in with your account. If you don't have one, create an account for the site or simply log in using your Google account.
Input the link that you wish the QR code to direct to.
Click on "Create" and copy the image of your QR code wherever you wish to use it! You can even print it on paper and use it independently from any device of your own.
QR codes are a practical tool for linking physical classroom materials to digital resources. They can be used to provide quick access to websites, videos, online quizzes, or instructions without requiring students to type long URLs. In educational contexts, this can support independent work and reduce time spent on task setup (Shubbik, 2025). QR codes are also frequently used for interactive learning activities such as stations, scavenger hunts, or group research tasks (Toloupe, 2022).
Another benefit is that QR codes can support engagement and classroom organization. For example, teachers can embed QR codes on worksheets, posters, or classroom displays so students can access extra support materials or extension tasks. Kraft (2024) argues that QR codes can help transform traditional learning activities into more interactive and technology-supported experiences, especially when combined with digital platforms.
However, QR codes also present challenges. One major limitation is accessibility: students may not always have a device available, and some may struggle with scanning or navigating digital content. Additionally, privacy and data concerns may arise depending on which QR generator is used and what data is collected (Cooper, 2022). For this reason, teachers should choose tools carefully and ensure that tasks are inclusive and clearly explained.
Overall, QR codes can be an effective classroom tool when used with clear instructions, accessibility considerations, and purposeful integration into learning tasks (Toloupe, 2022; Shubbik, 2025).
