110 Chapter 5 The addition of Educational Facility as a fixed main effect did not improve the General Development Model of NDW score (NDW7; see Table 5.10), however the interaction between Age and Educational Facility did (ΔΧ2 (NDW8) = 5.88; df = 1; p = .02).

The influence of Educational Facility is larger for younger pupils than for older pupils. We do however refrain from plotting the model in a graph because this would be difficult to interpret. A larger sample is necessary to confirm the effect whether a certain school type is better for younger pupils with regard to NDW than the other. Guiraud Index Score Example (3) and (4) illustrate our variable Guiraud Index Score. Both stories are from the same boy w and they show how the Baby Bird story evolved from Session 0 to Session 3. In a year the GIS of this boy’s stories increased from 1.18 to 4.09. Example (3): Subject number 0701; age 5;10; around 5 months in school; home language: Polish; Session 0; GIS 1.18. die vlieg. en die vlieg. poes vlieg en poes. een vlieg en poes. vlieg en poes en hond. vliegt. vlieg en poes en vlieg en poes en hond kijk. vliegt poes en hond, vliegt poes en hond. die die die. ja vlieg, ja hond. en poes. That one fly \[is a bird?\]. And that one fly. Puss, fly and puss. A fly, and, puss. Fly and puss and dog. Flies. Fly and puss and fly and puss and dog look. Flies puss and dog, flies puss and dog. That one that one that one. Yes, fly, yes dog. And puss. Example (4): Subject number 0701; age 6;10; around 18 months in school; Session 3; GIS 4.09. mam heb teruggevliegt en nog een keer gaan weg. en mam vliegt zie niet poes, maar is ie wel. poes springt op de boom. mam vliegt heeft baby is vliegt eten. en dan poes springt op de tweede baby. en dan hond komt, poes zie niet. en hond pakt van poes staart. en haalt van de boom. poes gaan wegrennen en hond achter poes.
