I administered a four question Pre-Post test in Spring 2012, Fall 2012 and Spring 2013. The Pre-Post test is attached for your reference. In Sp12 and Fa12, students showed great improvement from Pre to Post test, however in Sp13, the percentage improvement from pre to post test dropped drastically. Overall scores on the post test for 2012 were very high (see attached) and for Sp13 were low. There were two main differences from last fall to this spring that contributed to the lower Pre-Post test results. One was the change from the Aleks placement test to an easier placement test which allowed more underprepared students into the class and two was how I grouped students in the classroom. In the Fall, I regularly re-assigned groups of students for groupwork in the classroom. In Sp13, I allowed students to choose and keep their own groups. I feel that this led to a group mentality and when one person brought a negative attitude to the group, the rest of the group took on that attitude and started to slide. Next fall I will go back to assigning groups of mixed levels of students.
