Activating the WHOLE BRAIN in a Single Lesson!

The following narrative illustrates how the brain is activated in a typical WBT lesson - creating Teacher Heaven!

Class/Yes activates the students' prefrontal cortex, readying the brain for instruction.  Immediately following that with Hands & Eyes eliminates all learning distractions, allowing the prefrontal cortex to control the rest of the brain.  These two steps, together, take less than 10 seconds to complete with a classroom full of students, and yet they are ESSENTIAL to any successful lesson.  As the commands are given and students respond, points are awarded on the Scoreboard.  Thus, the limbic system is activated causing small emotional jolts, either positive or negative, causing the brain to again narrow its focus on the learning about to occur.  In order to negate habituation (think sea slug here!) the scoreboard has built-in levels so that students view it in the same manner as a video game, always trying to get to the next level (and the teacher looks oh so cool!).  Within a total of 30 seconds, we have already activated two VERY important areas of the brain, and the brain is now ready to absorb all it can - within about 30 seconds until its short-term memory dumps its load and starts over.  I think of short term memory as a 32 GB flash drive that all information must pass through before being allowed onto the infinite hard drive of long term memory.  The brain either moves it toward the mainframe, or dumps it in the recycling bin.  Therefore, the instructor should only "teach" for about 30 seconds while students Mirror the teacher's gestures, just before "the dump" occurs, and then have the students Teach-Okay.  Now we are really activating some neurons!  During Teach-Okay, the students engage the visual cortex by seeing other people's gestures, the motor cortex by doing the gestures themselves which also activates those mirror neurons - the primal learning aspect of the brain, then Broca's area as they verbalize and Wernike's area as they listen.  Switch is used in order to maintain a balance of activation between Broca's Wernike's areas so that students don't get over or under activated based on their natural tendencies.  Now, because all of the students have rehearsed the 5 Classroom Rules, they know exactly what is expected, leaving no behavior choices to be made because their brains are VERY busy being activated by all this learning!!
