This week I toured Small Learning Community "C" with  Dean Chris Saheed. We  spent five to ten minutes in a variety of classes during Period 4 -- the last  period of the day.
Block classes are new this year. Teachers spent last year learning how to  teach in classes that are 30 minutes longer. They must get through the  curriculum in half the year. They wrote new syllabi -- which will soon be  available on the web. It is all supposed to lead to better teaching and  learning.
In Physics First, a freshman class, the teacher began with a brain teaser:  What experiences more air resistance: a feather or an elephant? What if the  feather is big and the elephant is small?
In an AVID elective, 10th graders chosen for their potential to go to  college, were going over the "rubrics" of how they would be graded in the class  -- whether they were tardy, completed homework assignments and how well they  were following basic tips of the class like finding "study buddies" and seeking  out teachers for help.
In an Honors Biology course, 11th graders were looking at slides -- slices  of onion, cheek cells etc. -- under microscopes, to answer  questions.
Upstairs on the 5th floor, seniors were taking a humanities course called  "Identities" for college credit.
Back on the first floor, a half dozen juniors and seniors were working in  the "virtual high school" corresponding with teachers through the internet,  studying music criticism, U.S. history in Vietnam and an assortment of other  electives not offered by CRLS.
How do the students like the block? Most say they do. It's less stressful  keeping track of work for four classes instead of seven. There are fewer  transitions to make. The day goes by faster.  
Teachers will continue training for the block this year. Other kinks still  need to be worked out. Some classes are too large, like the Spanish I class we  saw, and need to be split. Space could still be better organized. Better signage  is in the works.
It certainly looks like a productive place where a wide variety of learning  is going on.
