visual representation of the overall model used in this study (see figure 1). To determine<br />

whether the various facets of self-regulation, on-task involvement, and moderating<br />

effects of gender and school have a predictive influence on classroom learning<br />

behaviors in kindergarten a series of PLS models will be developed.<br />

PLS allows one to estimate constructs or Latent Variables (LVs) based on the<br />

shared variance of the manifest variables; individual variable residuals and unreliability<br />

associated with measurement error are minimized. That is, scores for the composite LVs<br />

are computed from principal components weights, derived from analyses of the<br />

manifest variables. Thus, a smaller set of theoretical variables is created, whose<br />

relations can be investigated without sacrificing information from the larger group of<br />

manifest variables. PLS is a method for modeling relations between sets of observed<br />

variables by means of latent variables, where a measurement (outer) model and a<br />

structural (inner) model is specified. Outer models demonstrate psychometric reliability<br />

of our latent variables. Whereas the inner models allow for estimation of predictivity<br />

utilizing both the inner and outer models, which allow us to test for discriminant validity<br />

when LVs are compared to the square root Average Variance Extracted (AVE), which<br />

represent the variance extracted by the LV from its indicator items (Esposito Vinzi, et al.,<br />

2010).<br />

It is favorable to use PLS in the current investigation because it allows for the<br />

creation of multiple linear regression path models without imposing the restrictions<br />

employed by other analyses, such as structural equation modeling, discriminant<br />
