Mindfulness Matters

In recent years, some schools have begun to introduce meditation, or mindfulness training, into their classrooms. During mindfulness training, students may be asked to sit quietly and observe their own thoughts and feelings to avoid being controlled by them. Mindfulness training can help students overcome anxiety (焦虑), control their behavior, and improve their ability to pay attention in class. Students are expected to learn how to meditate in order to reduce stress and do better in their schoolwork.

Among schools that already teach meditation, the results have been positive. In one study, teachers reported that after five weeks of mindfulness practice, their students were more focused. They also participated more fully in class. A middle school in San Francisco reported that a student meditation program led to higher attendance rates and better grades. Another study suggested that meditation helped students perform better on tests by improving their working memory and reducing their anxiety.

Many supporters believe that meditation training programs can also help students overcome stress. For example, Headstand is a mindfulness education program designed to help students overcome anxiety. A study concluded that ninety-eight percent of participating students felt less stressed after they completed the Headstand program. In another study, researchers in New Haven, Connecticut, followed students who participated in meditation and yoga classes three times a week. They found that after each class, participants had lower levels of cortisol, a stress hormone (激素), in their bodies.

Despite the positive results seen so far, critics also point out that much of the current research is not rigorous(严谨的) enough. Associate Professor Tamar Mendelson agrees that research on meditation in children is still in its early stages. However, even she insists that she has seen the positive impact of meditation on children. Others express worries that meditation is not a valuable use of class time. But many disagree. Denise Pope, a professor from the Stanford University, says, “This is something teachers can do immediately. You get a lot of bang for your buck and anyone who is against it isn’t thinking clearly.” Indeed, additional studies will surely strengthen our understanding of the benefits of mindfulness.

Although still in its early stages, research shows that meditation can help students learn to deal with anxiety and stress. As an added bonus, students of mindfulness training also report better concentration and gains in their academic performances. Therefore, meditation should be a part of every student’s school day. Participating in “stillness” can be just as productive as other school-related activities.
