176 Chapter 8 in scores on the pedagogical variables. The latter effect indicates that the influence of the pedagogical variables on narrative ability depend on the age of the pupils. 8.3.1 Pedagogical practices: focusing on teacher behavior Due to logistical issues, some observations of the teachers took place after the assessment of the first (or first two) MAIN assessments op the pupils. Therefore, 54 MAIN scores obtained from pupils prior to the CLASS observations, mainly from Session 0, were taken out of the analyses. In total 114 cases from 38 different pupils could be taken into account, and therefore new developmental models needed to be modelled first with these 114 cases for all aspects of microstructure and macrostructure. After that, the analysis of the relation of pedagogical practices and narrative ability continued. The two significant different outcomes between school types on aspects of teacher behavior measured by CLASS obtained in Chapter 6, namely Positive Climate and Regard for Student Perspectives, will be added to these new General Development Models. Microstructure In the next three sub-sections, the microstructural elements of the narrative ability will be modelled and related to learning environmental aspects, based on observed teacher behavior. First the Number of Different Words (NDW), then the Guiraud Index Score (GIS), and finally the Measure of Lexical Richness (MLR) will be modelled. Number of Different Words( NDW) From the comparison between the consecutive models (see Table 8.4) it is apparent that a model with a fixed linear component – allowing for differences in Age – fit the data better than a model with only an intercept (Δχ2 (NDWb) = 48.08; df = 1; p < .001). Neither the variance within individuals (NDWc) nor the variance between (NDW d) depends on the age of the participants. Further, adding Age2 to the model did not improved the fit significantly (NDWe). Hence, in the final model (NDWb) a fixed effect of Age is needed, and with this model we continued the analysis.
