Create an environment that is conducive to studying. This means your high school freshman's study time should be free of distractions such as TV, cell phones, MP3 players, instant-messaging or family disruptions. Have nutritious snacks and meals on hand for periodic breaks.
Encourage your freshman's efforts at studying hard, even if they do not produce A's. Students who receive support for their efforts, as opposed to their intelligence, will feel more self-worth even if they do not achieve high marks and will be encouraged to work harder. And your student will be learning a valuable lesson for the future that effort in life is more of a guarantee of success than intelligence.
Enlist a tutor. A tutor will be able to identify problem areas that require more attention, as well as keep your student on track with respect to the amount of study hours required. In addition, a tutor can help with study habits, speed-reading techniques and mnemonic aids.
Alleviate pressures on your student. Many high school freshmen are involved in extra-curricular activities, such as sports, student body meetings or other high school clubs, while others have part-time jobs. While it is healthy to maintain a balanced lifestyle, ensure that your student is not being pulled in too many directions at the same time. Advise your student to consider withdrawing from one or more extra-curricular activities, at least until his marks have improved.
Become involved in your student's studies. Even if you are not familiar with the subjects he is taking, show an interest in what he is learning and ask questions about the material. Students who can find some enjoyment in what they are learning and can share in this enjoyment will be encouraged to perform better.
