You already made your ArrayList static, make it public as well. and use that by your class name. and populate your ArrayList in onPostExecute(); like

     protected void onPostExecute(ArrayList... result) {

       YourClassName.directoriesTeacher.clear();
      }

      YourClassName.directoriesTeacher.addAll(result);

     }
