Determining ZPD from AR Testing Results
Following the AR procedure, have your students tested on their reading comprehension of Walk Two Moons. Use the test results as your guide on how to find out your student's zone of proximal development (ZPD) and how to hone his/her reading comprehension skills by following these steps:
1. If your student scores a 3, for instance--a score below the AR level of Walk Two Moons (4.9)--subtract one full point from 4.9, arriving at the reading level 3.9. This means that the reading levels of books that you can recommend to this student should have points ranging from 3.9 - 4.9.
2. If your student scores a 5, for instance--a score higher than the AR level of Walk Two Moons, subtract 0.5 from 4.9 to arrive at 4.4, and add 0.5 to 4.9 resulting in 5.4. Therefore, the range of books this student should read is from 4.4 to 5.4.
3. If your student scores a 6, for instance--a score way higher than the AR level of Walk Two Moons, subtract 0.5 from 4.9 to arrive at 4.4, and add a full point (1.0) to 4.9 to arrive at 5.9. Therefore, the books this student should read would have to range from 4.4 to 5.9.
