This study proposed to identify and select high and low-effectiveness schools in Baja California based on ENLACE (Quality of Educational Attainment Exams) scores and context tests. A representative sample of 85 schools and around 7,000 students was obtained for 2010 and 2011. Hierarchical linear models were applied to calculate residual scores at a school level. After adjustment of the 8 final models, which isolate the effect of significant contextual variables, statistical criteria were used to select 15 schools with high and low residual scores. The results show that the distributions of schools selected are similar in both cases to the reference population. The results show the robustness of the selection procedure used and highlight its significance in detecting good practices in high-effectiveness schools. [ABSTRACT FROM AUTHOR]

The multivariate characteristics of the IL-HUMASS scale are studied. This scale is formed by 26 Likert scale items and 4 dimensions and evaluate the information literacy self-perceived level of students. A sample of 402 subjects, all of them Spanish future teachers from secondary education, is obtained. It is implemented a multidimensional scaling technique by ALSCAL based on the distance matrix from the data. The results detected two empirical dimensions, which accounted for 95.9% of the variance. The first dimension is related to the level of familiarity with the content of the item and the second dimension is related to cognitive or instrumental aspect of the item. In the conclusions, two dimensions obtained are connected with the original scale, in relation to the four theoretical dimensions. On the other hand, the conclusions highlight the importance of considering the two dimensions obtained, in addition to the classical dimensions, in the design of assessment scales of the construct information literacy.
