ICTs have the potential to empower teachers and students by promoting 21st century skills, but there is limited data to prove these benefits. While ICTs are believed to improve student achievement when used appropriately, the impact remains difficult to measure and debateable. Positive effects are more likely when technology supports existing teaching methods rather than replacing them. Computer-assisted instruction has shown slight improvements on standardized tests, but it is unclear if this translates to real learning. The goals for using ICTs in education are often loosely defined, making them less effective. Different school subjects integrate technology differently, with simulations and word processing showing benefits. Student access outside of school and how technology is incorporated into the classroom also impact results. [/SUMMARY]
