"I really took away so many things!  I loved all your suggestions! At my class meeting today, one of the students shared how much he enjoys the choral response we started doing.  Many other students agreed with him.  I have been incorporating math vocabulary more frequently.  I really felt inspired after our day together!"

Item Analysis

Positively Impacting Mathematics Education Since 1995

Diana's passion for teaching began in high school when she experienced first hand the contrast between a traditional lecture format, and the inquiry based teaching strategies endorsed by NCTM and the Standards for Mathematical Practice.  After several years as a classroom teacher, Diana shifted her focus from students to teachers to increase her positive impact on mathematics education.  Due to her rich experiences and self-reflective nature, Diana has become highly effective at teaching math content to teachers while being a role model in best pedagogical practices.  She has developed frameworks and protocols to help teachers at all levels improve teaching and learning outcomes.  Her unique way of connecting with people enables teachers and administrators across the country see the vision behind great mathematics instruction.
