Data to Inform Curriculum: Milestones Domains

Most of our test score data visuals show data at the subject level. They answer questions like, “how did school x do in 4th grade math?” But the state test also returns results at the domain level. This allows us to look beyond overall math performance and measure which parts of last year’s math curriculum were the most successful.

The view below shows Milestones math domains with Fickett elementary highlighted. We can see that Fickett 4th grade students performed highest in the “Numbers and Operations-Fractions” domain. In fact, their performance on the fractions domain was nearly as high as Wesley and Burgess- two schools with significantly lower poverty levels.

Mouse-over or tap a data point to see the actual results. We can see that 44% of Fickett students scored in the “remediate” category for fractions, which is the lowest level of domain performance, and 31% scored in the “accelerate” category, which is the highest level. The tool-tip also shows that the fraction domain has a 30% content weight, which is the highest-weighted domain for fourth grade math.

Use the school list on the left to highlight different schools, and the drop-down menus to view different subjects or grade levels. The cluster and NCE filters are useful for reducing the amount of data shown.

The x-axis of the domain graph is the NCE score for each domain. The NCE score is an average score across students, but on a common scale that allows us to compare domains. This is important because some domains have different difficulty levels, and the writing sub-domains are graded on a different scale. For more detail on domains, mouse over the blue “domain information” button. For even more detail, see the Milestones test blueprints and the item samplers.

The domain view is a nice compliment to our state percentile rank visual. The state percentile rank visual allows a user to quickly see overall strengths, weaknesses, and trends and the domain view can then help investigate root causes.

The next view highlights English Language Arts (ELA) results for Kindezi. The view shows that narrative writing is a relative strength for Kindezi students. Narrative Writing requires a student to write a short story and is scored on a 0-4 point scale. The last two writing domains, “Writing-Nonfiction Content” and “Writing-Nonfiction Grammar” are based on a non-fiction essay1. Content measures idea development, organization, and coherence on a 0-4 point scale and Grammar measures language usage and conventions on a 0-3 point scale.

The last view shows results for high schools with Carver Early highlighted. We can see that Carver Early does well in economics domains, particularly personal finance.
