Video games can aid in the learning process by improving skills like logic, memory, visualization, and problem solving. When designed to address a specific problem or teach a skill, games have shown considerable success. Studies have found that surgeons who played the Nintendo Wii before a virtual surgery scored higher than those who did not. Military researchers are also exploring how video games can help teach soldiers skills in a way that supplements traditional training methods. However, students still need guidance when using games and simulations for learning.
