A first step toward establishing a respectful classroom learning community is acceptance of all ideas and answers—regardless of any obvious errors. Rich mathematical discussions cannot occur if this expectation is not in place. We must remember that wrong answers are often rooted in misconceptions, and unless these ideas are allowed to be brought to the forefront, we cannot help students confront their thinking. Students who are in safe learning environments are willing to risk sharing an incorrect answer with their peers in order to grow mathematically. It is important to model and expect the acceptance of all ideas without derogatory comments. As educators we can model this by recording all answers to be considered without giving any verbal or physical expressions that indicate agreement or disagreement with any answer. The teacher may need to practice having a “blank face”. Students look to teachers as the source of correct answers. Part of building a safe learning community is to shift this source of knowledge to the students, by equipping them to defend the thinking behind their solutions.

① to hide the teacher’s confusion about mathematical misconceptions
② to avoid signaling whether any answer is correct or incorrect
③ to encourage students to speak with no facial expressions
④ to record wrong answers before correcting them for students
⑤ to show equal disappointment at both right and wrong answers

The usual intercity traveler moves slowly through the station area. The passenger may not be familiar with the routine, have baggage to handle and check or retrieve, have a long wait for connections or delayed trains, and may require information, food, and a comfortable place to sit. Commuters, on the other hand, are familiar with the route through the station, have little or no luggage, and are usually in a hurry. They want direct access to or from local streets and transport. These two types of traffic should be kept separate to avoid conflict and confusion. In some large stations such as Grand Central Terminal in New York City, commuter and intercity trains arrive and depart on different levels. In smaller stations, separate platforms should be used and traffic routed so that the two lines of movement do not cross. In some instances, separate stations are in use. Clear and concise direction and routing signs and other means of channelization are desirable.

① to give commuters easier access to food and seating
② to prevent the two passenger flows from interfering
③ to make delayed intercity trains leave on time
④ to provide baggage services along separate station routes
⑤ to help intercity travelers learn the station routine faster
