Final answer:
Parents can mediate children's television viewing by setting time limits on screen time, which is crucial for mitigating negative effects such as poor academic performance, childhood obesity, and potential increases in aggressive behavior.
Step-by-step explanation:
One way that parents can mediate children's television viewing is by setting time limits on screen time. This approach can help manage the influence of TV content on children's behavior. Numerous studies have pointed out the potential negative effects of excessive TV watching, such as interfering with students' ability to prepare for exams, leading to poor academic performance, and contributing to childhood obesity. Moreover, watching violent media can possibly affect aggressive behavior and desensitize individuals to violence. Therefore, parental mediation, like setting limits, along with encouraging physical activity and healthy eating, is crucial for a child's overall well-being and development.
