The goals of the study were to examine the predictive power of general cognitive ability, working memory, and self-efficacy in first grade for academic functioning of children at risk for learning disabilities in second grade. The study involved 82 children (age 6-7 years) from five local public elementary schools in middle-class neighborhoods in Jerusalem, including 41 children at risk for specific learning disabilities and 41 typically developing peers. In the first stage of the study, (performed at the end of first grade), general cognitive ability and working memory were assessed using subtests from the Wechsler Intelligence Scale for Children (the subtests consisted of:  Vocabulary and Block Design for general cognitive ability; Arithmetic and Digit Span for working memory). Academic self-efficacy was rated using a structural interview. At follow-up, academic functioning was assessed at the end of second grade. A serial-multiple mediation analysis revealed significant mediating roles for levels of performance in the Arithmetic subtest and for academic self-efficacy in predicting the academic functioning in second grade. The significance of the Arithmetic subtest, based on contemporary research on the structure of the intelligence was proposed. Educational implications call for sensitizing teachers to the unique role of academic self-efficacy in shaping trajectories of academic functioning development among children with RLD and in using effective strategies of promoting self-efficacy.

In this study I examine the academic self-concept (ASC) of students who changed from vocational to academic tracking at the transition to upper secondary education in Germany. I ask (1) how their ASC differs to the ASC of their established peers in academic tracking, and (2) how their ASC is affected by the change in the learning environment. Using a subsample of the German National Educational Panel Study (NEPS; N = 4109), findings show that newcomers to academic tracking have a stronger ASC than their peers. However, social differences between the social milieu of origin and the one prevailing at school significantly reduce the ASC. These differences are interpreted as being social-habitual and tested via socioeconomic status, cultural capital, and parental solidarity expectations at the school level. Results differ according to immigrant origin; immigrant newcomers to academic tracking have higher ASC than their established peers, and context effects are more influential. I complement previous research by using a quantitative approach to test the theoretical mechanisms of a qualitative research perspective on upward mobility.

The following research presents the outcomes of a cohort study investigating formal thinking skills among first and second-year secondary school students. A specially crafted instrument, the Logical Thought Performance Test for Adolescents (LTP-A), was employed to gauge the level of formal thought. The LTP-A assesses various aspects, including: combinatorial reasoning; proportional reasoning; permutation; inferences derived from exclusive and inclusive disjunction; biconditional and asymmetric implication; and, modus tollens. The study compares the achievements of four student groups from two educational institutions at two distinct time points, with a thirty-year gap. The independent variables include the sociocultural level and the epochal aspect. Methodologically, one-way analysis of variance and cluster analysis were performed, showing significant differences in relation to sociocultural level. Results suggest that the sociocultural factor outweighs epochal differences. Then, a content analysis of some answers was carried out to detect resolution strategies, some conceptual categories and types of errors. Conclusions explore the moderating role of students' sociocultural levels, and provide educational recommendations.
