This article presents the results of a study of mathematical fluency in high school students. We provide a definition of mathematical fluency and illustrate the relevance of the research by presenting an overview of studies examining mathematical fluency development and its relationship with success in mathematical disciplines.
A computerized test “Problem Verification Task” (Tosto et al., 2013) was administered to 692 high school students from one public secondary school (grades 9/10/11: n = 336/210/146) in the Moscow region. The stimuli consisted of 48 elementary arithmetic equations along with answer options. To indicate a correct answer, participants were instructed to press the corresponding key on the keyboard as quickly as possible.
Two-way ANOVA was used to estimate grade and sex similarities and differences in mathematical fluency at the high school level.
The current study has two primary findings: (1) students differed in math fluency across grades, and (2) there were no sex differences in mathematical fluency at the high school level. ANOVA exhibited significant differences in mathematical fluency among all three groups of students at grades 9, 10 and 11 with a 19% effect size. These results may be associated with the accumulating effects of the educational process: high school students in each subsequent year of schooling demonstrate a higher level of mathematical fluency on average compared to the previous year. At the same time, we observed no sex differences in mathematical fluency at the high school level. The results are discussed in terms of educational effects.

This study examines the role of cognitive characteristics in the success in learning Russian, assessed through teachers’ grades and test scores on standardized state exams.
This paper examines the relationship between cognitive characteristics, such as nonverbal intelligence, working memory and speed of information processing, and the results of the Unified State Exam for 11th grade students, the Basic State Exam for 9th grade students and the traditional assessment of Russian language learning.
This study involved students in the 9th and 11th grades from four educational institutions in the Moscow and St. Petersburg regions; 427 students were studying in the 9th grade (50.3% were boys) and 398 students were studying in the 11th grade (44.8% were boys).
This study concluded that expert assessment of Russian language learning is more associated with successful test scores on the Unified State Exam (r = 0.71, p < 0.01) than with the results of the Basic State Exam (r = 0.46, р < 0.01).
This study showed that at the lower and upper levels of secondary education, nonverbal intelligence is a significant predictor of success in learning the Russian language according to expert estimates. In addition, we found differences in the relationship between cognitive performance and success in learning the Russian language as assessed by tests. Nonverbal intelligence contributes significantly to individual differences in scores for the Unified State Exam in Russian, while the contribution of cognitive characteristics on the Basic State Exam is not statistically significant.

This study, which is a part of a Moscow longitudinal twin project, aims to explore genetic and environmental contributions to inter-individual variability of temperamental traits in adolescence on the basis of a Russian sample. 85 monozygotic (MZ) and 64 same-sex dizygotic (DZ) twin pairs aged 12 – 14 years completed the children version of Rusalov Structure of Temperament Questionnaire (C-STQ). The results of model-fitting analyses indicate considerable hereditary determination of individual differences in 3 out of the 8 C-STQ dimensions - social tempo, objectrelated emotional sensitivity, and social emotional sensitivity. Non-shared environmental effects explained the rest of the total variance in these dimensions. Individual differences in the other STQ dimensions were due to environmental factors.

Gene-environment correlations have been studied in behavior genetics since the beginning of the 1980s, including genetic effect on the perceived family environment; however, the majority of studies have been based on retrospective self-reports. The current study is meant to analyze the sources of variance (complementary genetic factors, shared and non-shared environmental variance) in perceived family environment with Russian adolescent twins. Perception of family environment was measured with the Russian version of Family Environment Scale (Moos & Moos, 1981). The structural equation model in "Mx"(Neale, Boker, Xie, & Maes, 2004) was employed to estimate the influence of genetic and environmental factors on adolescents' self-reports. The environmental variance components are prevalent for most FES scales (6 of 10). The shared environment was significant for 3 primary grades and the Organization factor, the complementary genetic variance was revealed for 2 primary grades and the Expressiveness-Control super-order factor. These results are generally consistent with previously reported moderate heritability of FES scales, although the heritabilities for the Conflict scale and the Structure super-order factor appear to be relatively high. The gene-environment correlation might be a possible explanation for these findings.

Belova A.P., Sabirova E.Z., Malykh S.B. (2012). Nature of Individual Difference in Liability to Depression in Russian Adolescents. Psychology in Russia: State of the Art, 5, 133-141
The Influence of genetic and environmental factors on liability to depression in Russian teenage sample was investigated. 196 twin pairs aged 13 to 17 (M=15,2) from Moscow, Izhevsk and Bishkek took part in the survey. We have found out that genetic factors had an effect on individual difference in depressiveness among Russian teenagers: more than 50% of variance was explained by additive genetic factors which correspond to international results. The biggest genetic influence was obtained for such scales as negative emotions, negative self esteem and externalization which are the most replicable factor scales in CDI structure worldwide.
