Background. Some studies connect the popularity of food-tracking apps to an increase in restrictive eating and other disordered eating behaviors and find those apps harmful for psychological well-being, but there is a lack of empirical studies, especially of Russian samples.

Objective. To examine the connection between disordered eating symptoms, psychological well-being, and the use of a mobile food-tracking application.

Design. The participants were 26 women aged 18–30 (M = 21.96; SD = 3.33); 24 completed the study. During the pre-test, the participants completed the Dutch Eating Behavior Questionnaire (Van Strien et al., 1985), the Eating Attitude Test (Skugarevskiĭ, 2007), the Hospital Anxiety and Depression Scale (Ma et al., 2023), the Situation Inventory of Body-Image Dysphoria (Baranskaia & Tataurova, 2011), and a socio-demographic survey with additional questions related to food tracking, weight, and disordered eating. The experimental group was then tasked with tracking their food consumption with a mobile app for a month. The test battery was completed again immediately after the experiment ended, and for a third time one month later.

Results. The comparative analysis showed a decrease in anxiety throughout the study, with a tendency-level increase in depressive symptoms by the end of the experiment. Contrary to expectations, emotional and external eating decreased during the experiment, while restrictive eating did not change. However, the risk of general disordered eating behavior increased one month after the experiment. The correlations between psychological well-being and eating behavior changed during the study. Immediately after the experiment, more correlations between eating behavior, body dissatisfaction, anxiety, and depression emerged, while at the later cutoff, correlations with depression and anxiety became insignificant.

Conclusion. The study had mixed results, contradicting some previous research. Both emotional and external eating decreased along with anxiety levels; however, general disordered eating symptoms increased after food tracking.

Background. The higher education system today requires students to be able to conduct independent academic work outside the educational system. Some data has been developed on the general educational skills of students; however, the available works are most often devoted to the skills of students in the humanities, yet in technical fields such as engineering, scientific knowledge becomes outdated much faster, which is associated with the global digitalization of society.

Objective. To assess the Diagnosis of Basic Learning Skills Task Battery (Metodika diagnostiki osnovnykh uchebnykh umenii) as modified for engineering students.

Design. The study was conducted in several stages. First, we created six sets of tasks for assessment of basic learning skills, based on the subject matter of engineering disciplines for students at three educational stages (first-year students, fourth-year students and second-year master students). Next, engineering students at different educational stages at Moscow Technological University (N = 135) took part in testing of the proposed task battery. They were also administered the Diagnosis of Supplementary Learning Skills Inventory by Ilyasov (questions for self-assessment), and a survey of academic performance and socio-demographic variables. Skills of memorization and consolidation of knowledge were not assessed in the current study. 

Results. Confirmatory factor analysis allowed us to establish high convergent validity of the task battery (p = 0.001). Internal consistency of the separate scales of the battery was acceptable (Cronbach’s aranged from 0.692 to 0.839). Тhere were significant positive connections between the modified task battery for diagnosis of basic learning skills and the battery for diagnosis of supplementary learning skills, academic performance, and educational stages.

Conclusion. The results demonstrate that the modified battery is a valid and reliable tool for measuring basic learning skills.

Background. Studies have shown the great importance of early mathematical development as a predictor of subsequent success, which poses the question of how to organize preschool mathematical education with a view to the children’s age characteristics, including their cognitive development. In other words, mathematical concepts and actions should be formed with the help of teaching resources appropriate to the child’s development.

Objective. To determine the effectiveness of three teaching resources (examples, models, and symbols) in formation of the concept of magnitude in older preschoolers (ages 6–7) with different levels of executive function.

Design. Four training programs (with 15 twenty-minute lessons each) were developed and conducted in a formative experiment for older preschoolers with different levels of development of executive functions. The lessons addressed the concept of magnitude (length, area, volume), using different types of teaching resources: exemplars (in traditional and game variants), models, and symbols. The total sample of 116 subjects (44% boys) was divided into 4 groups for each of the programs, plus a control group in which no sessions were conducted. The groups were equalized according to the initial level of development of concepts of magnitude and the level of development of executive functions.

Results. There was a statistically significant increase in the quality of mastery of the concept of magnitude in three experimental groups (“symbolic,” “traditional,” and “traditional with game elements”) compared with the control group. The formative effect of the “model-building” program showed no significant differences from the effect of the child’s natural development (the control group). We also showed that children with a low level of regulation learned mathematical concepts more effectively with the “symbolic” program; children with a medium level of regulation with the “symbolic” and any variant of the “traditional” program; and children with a high level of regulation with the “symbolic” and “model-building” programs.

Conclusion. The findings underline the importance of both the type of teaching resources used and the level of development of voluntary regulation, when teaching mathematics to preschoolers.
