Mobile devices and apps can provide educational benefits if used responsibly in the classroom. They give students access to tools for subjects like math, science, languages, and more. Apps exist for studying abroad, identifying plants and insects, step-by-step problem solving, and lowering textbook costs. Teachers can also use mobile apps to take attendance and share grades with parents. However, some argue that students may become distracted, and that mobile devices are not always the best way to learn. Opinions vary on whether mobility in the classroom is useful or if it poses too many problems.
