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 debated. 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 subjects integrate technology differently, with simulations and modeling software effectively used in STEM fields. Student motivation increases with ICT use, but appropriate ages and settings for technology introduction are still debated.
