You could override setUserVisibleHint event of the fragment to know if its visible to the user and then load your data. something like following:

boolean _areLecturesLoaded = false;

@Override
 public void setUserVisibleHint(boolean isVisibleToUser) {
     super.setUserVisibleHint(isVisibleToUser);
     if (isVisibleToUser && !_areLecturesLoaded ) {
      loadLectures(); 
      _areLecturesLoaded = true;
     }
 }
