Study hours...plain and simple. I know some people will complain, call it hazing, or what not but seriously, putting a new member class in the library for three hours together not only encourages studying but also bonds of sisterhood. Besides, by the definition on
www.stophazing.org study hours are not hazing at all.
It's simply another "activity" for new members to go to, but in this case it's to help them get off on the right step, making sure that they are up to speed in their classes. And no one can skip out on them b/c they have to study, unless they absolutely have to use a computer and don't have their own laptop...
There are other methods to encourage scholarship, like my chapter gives a $500 scholarship and a 14k gold Beta Theta Pi ring to any pledge who achieves a 4.0 in their first semester. However this doesn't really help our pledges get used to college, or help them to balance the other required activities.
