In the L2 Motivational Self System (L2MSS) motivation is conceptualized to be generated by discomfort associated with the learner's experience of a discrepancy between their current L2 self, and their ideal L2 self. However, in the L2MSS model, this discrepancy is not operationalized. A questionnaire containing measures of current L2 selves was…

Using structural equation modeling, we examined the relationship of Hispanicism on recent substance use and whether Americanism moderated the effect in a sample of 1,141 Hispanic adolescents. The Bicultural Involvement Questionnaire (BIQ) was used to determine the degree of individual comfort in both Hispanic (Hispanicism) and American…

The present study investigates the empirical separability of mathematical (a) content domains, (b) cognitive domains, and (c) content-specific cognitive domains. There were 122 items representing two content domains (linear equations vs. theorem of Pythagoras) combined with two cognitive domains (modeling competence vs. technical competence)…

For adaptation and personalization of game play sophisticated player models and learner models are used in game-based learning environments. Thus, the game flow can be optimized to increase efficiency and effectiveness of gaming and learning in parallel. In the field of gaming still the Bartle model is commonly used due to its simplicity and good…

While recent evidence has indicated that experienced racial discrimination is associated with increased depressive symptoms for African American adolescents, most studies rely on cross-sectional and short-term longitudinal research designs.

I use a unique dataset containing grades given by teachers, scores obtained anonymously by pupils at different ages, and their course choice during high school. Based on double-differences, the identification of the gender bias in grades suggests…

Structural equation modeling was used to test a theoretical path model of church engagement, personal spirituality, and mentoring relationships on depressive symptoms, involvement in risky behaviors, and self-reported grades among Korean American adolescents. It was hypothesized that personal spirituality and mentoring relationship quality would…

In this article, we test: (a) the relation between school-based extracurricular participation and indicators of positive and negative development across a range of activity contexts, and (b) a mediation model linking activity participation, prosocial peers, and development. Extensive survey information was collected from a predominately White…
