Abstract The intent of my project was to examine the way I assess my students’ math in my 9-12 Montessori classroom given the new Common Core standards. The study involved six students, varying ages 9-11, in a public school setting. Data collection methods included pre- and post- assessments, observations, written responses to Webb’s Depth of Knowledge (DOK), and a brief questionnaire about the attitudes toward the various types of assessment (See Appendix A). The results of the data analysis showed an average increase of 84% in grade level achievement after practicing with the DOK, as well as an improved student enjoyment and enthusiasm for learning when compared to traditional lessons. The results of this action research investigation indicate that students perform better on Common Core math assessments after practicing with the DOK, as the DOK provides an outline to enable students to think critically.
