What I of ALL Teachers (not only SLA)

Chris Lehmann posted an article about what he expects out of Second Language Acquisition (SLA) Teachers and I thought to myself..."This is what should be expected out of every teacher."  As a current student and future educator I am constantly critiquing my professors, myself, and my classmates on how well they teach as well as thinking about what I would love for them to do to make things better for my learning.  Included in this constant analysis would be instances where a teacher says one thing and completely disregards what he/she is saying just a few minutes later.  The following is an example of what I mean shown in a dialogue between professor and class while learning about ADHD....

Professor (While referring to the powerpoint): "As you can see the average child with ADD cannot concentrate on a single subject for an extended period of time."

Student 1: "How long is the attention span for your normal college student."

Professor:  "Well I would say that about after 35-45 minutes students will start to wander and 'tune things out'"

Class now continues for an hour and a half going through the powerpoint....

Professor: "Okay we will take our break now."

Do the math on that one for me and practice what you preach.  You just told me that I'm most likely going to be losing attention after 40 or so minutes so why are you lecturing to me for over twice that amount of time?   With all of this being said I would like to add #11 to Lehmann's list and generalize it to all teachers.

#11) Please be accountable for what you teach and give me the best opportunity to succeed in your class.  Even if that is a two minute break where I can get up and just stretch without missing anything, it would make a world of difference and optimize my learning. Thank You.
