Teaching Decorum or Davening?

The following was shared from a reader about their synagogue's latest attempt to change the atmosphere of the shul.  It will be interesting to see what will be the next quick fix - as discussed, Dr. Levitz does identify this as one of the less successful attempts to break the "cycle of rebuke, resistance, and resentment".  What are your thoughts?

As you know, we've been considering ways to improve decorum in the Main Minyan. One area of concern is the disruption caused by adults and children coming in and out of the sanctuary during Torah reading and the Rabbi's drasha.

To address this issue, starting this Shabbat, we are going to lock three of the four outer central doors of the sanctuary (on the main level)  during Torah reading and the drasha. The doors will be locked from the outside only. The doors to the balcony will remain unlocked at all times.

During Torah reading and the drasha, the outer door on the far right (leading to the Main Sanctuary vestibule) will remain unlocked. The inner side door will be monitored by a volunteer who will permit adults and children to enter at breaks in the Torah reading and will let adults in at appropriate points in the drasha. Children will not be allowed to enter at any time during the drasha, so if your child is able to sit quietly during the drasha, please have him or her in the sanctuary before it begins. It is important that children understand this new practice and we ask that you explain the guidelines to your children.

Members who need to step out can of course do so at any time and are asked to use the door on the right as well.

We would appreciate male volunteers to help us monitor the side door. The volunteer will sit inside the sanctuary and will therefore not miss either laining or the drasha
