In the state of Texas, a new law took effect on September 1, limiting what public social studies teachers can teach. The bill passed in the state legislature on an almost perfect party-line vote.

Among other things, the law, House Bill 3979, mandates that in required courses,

a teacher who chooses to discuss [a particular current event or widely debated and currently controversial issue of public policy or social affairs] shall, to the best of the teacher’s ability, strive to explore the topic from diverse and contending perspectives without giving deference to any one perspective.

Today, NBC News has reported on the effect this law is having in the Dallas/Forth Worth suburb of Southlake, where the school district is already embroiled in a political battle over racism. The district’s curriculum director was recently recorded (surreptitiously) during a training session with teachers, acknowledging their fears about the law. She told them,

We are in the middle of a political mess. And you are in the middle of a political mess. And so we just have to do the best that we can. … You are professionals. … So if you think the book is O.K., then let’s go with it. And whatever happens, we will fight it together.

But she added, giving an example of a potential conflict,

As you go through, just try to remember the concepts of [H.B.] 3979, and make sure that if you have a book on the Holocaust, that you have one that has an opposing—that has other perspectives.

Teachers heard on the recording reacted with shocked disbelief, speculating that this directive would apply to a book like Number the Stars, a widely taught historical novel about a Jewish family in Nazi-occupied Denmark.

She said, “Believe me, that’s come up.”
