1. USING GRAPHICAL DISPLAY by John Froelich www.lookingatlearing.org A Picture is Worth a Thousand Words:

2. Graphical Display Principles Large amounts of data can be displayed in a small space Relationships can easily be displayed and interpreted Context for the displays is central to understanding Displays should be centered around simple, well- understood concepts

3. Today: Graphical Displays… Using change in percentile ranking to show actual growth vs expected growth. MCA Strand for Reading and Math using state means and Standard Deviations for context. These data will provide information to help plan curricular emphasis NWEA (CALT/NALT) Reading and Math as predictors for future MCA achievement. Using strand information to plan curricular emphasis. Using Looking at Learning to display proportion of time devoted to various activities during instruction.

6. Strand Information Different difficulty each year—you can not compare strand data from one year to another Different # of items in each strand each year The only possible analysis is to compare the % correct of the school to the % correct of state Knowing the standard deviation add context to the meaning of the size of the difference The standard error needs to be considered to know if the difference has some significance

16. NWEA CALT/NALT/MAP NWEA tests include scale scores for overall and strands. The scale score for each has a similar meaning: that is a scale score of 206 for the overall or any strand has similar difficulty meaning. NWEA norming study includes national norms for each grade level (percentile rankings) and growth norms. (A year’s growth keeps students at same %tile from year to year.) Mpls schools have calculated correlations for fall scale scores to spring MCA in reading and math. (.87) NWEA has sample problems for strands are various scale score levels—adding context for teachers.

17. NWEA CALT/NALT/MAP to use the conditional format Put NWEA data into an Excel spreadsheet Sort by grade level Select cells for reading or math scale scores and strands Open format spreadsheet – place cursor on appropriate cell and copy Go back to NWEA data—choose “Paste Special” and then “Format”

18. is an innovative assessment tool used to measure and guide classroom-level instructional changes during school improvement efforts.

19. Looking at Learning is an intuitive software program that automatically calculates duration and student participation for all activities generates reports including graphs for individual observations or aggregate reports for any combination of observations allows observers to add comments during observations is effective when used by teachers observing each other is a unique tool for staff development - not teacher appraisal

20. Looking at Learning measurement focus Is based on the student’s point of view, not on the teacher’s point of view Is based on constructivist learning strategies Recognizes the importance of lesson design that emphasizes the cognitive purpose for activities Recognizes that what happens in the classroom is the true indication of whether any reform effort has had the intended effect
