The purpose of the study was to determine the peculiarities of programmed teaching of a cartwheel to girls aged 15. Material and methods. The study participants were 20 girls aged 15. The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. To solve the tasks set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of training tasks; pedagogical experiment, methods of mathematical statistics, factor analysis, nearest neighbor analysis. Results. The analysis of similarities revealed that the program components are interrelated. Series of training tasks ІV, V and VI have the highest correlation. Series of training tasks І, ІІІ and IV are combined into one group and provide conditions for teaching girls aged 15 the cartwheel. Conclusions. The study obtained factor models of the teaching program, which explain 70.645% and 68.468% of the variation of results. The models characterize the two-factor structure of the teaching program where training tasks are closely connected with one another, which indicates their effective selection. It was found that the tasks of series I, II and III, and the tasks of series III, IV and V are most connected with one another, which confirms the combined nature of the method of algorithmic instructions. Optimization of the number of repetitions of the entire exercise (series of tasks VI) depends on the amount of exercises of the second and fifth series of training tasks.

This study is aimed at investigating the dimensionality of the situational version of the Brief COPE, a questionnaire that is frequently used to assess a broad range of coping responses to specific difficulties, by comparing five different factor models highlighted in previous studies. It also aimed at exploring the relationships among coping responses, personal goal commitment and progress. The study involved 606 adults (male = 289) ranging in age from 19 to 71. Using confirmatory factor analysis, we compared five models and assessed relationships of coping responses with goal commitment and progress. The results confirmed the theoretical factor structure of the situational Brief COPE. All the 14 dimensions showed acceptable reliability and relationships with goal commitment and progress, attesting the reliability and usefulness of this measure to evaluate coping responses to specific events.

The Pittsburgh Sleep Quality Index (PSQI) is a widely used measure for assessing sleep impairment. Although it was developed as a unidimensional instrument, there is much debate that it contains multidimensional latent constructs. This study aims to investigate the dimensionality of the underlying factor structure of the PSQI in a multi-ethnic working population in Singapore. The PSQI was administered on three occasions (baseline, 3 months and 12 months) to full-time employees participating in a workplace cohort study. Exploratory factor analysis (EFA) investigated the latent factor structure of the scale at each timepoint. Confirmatory factor analysis (CFA) evaluated the model identified by EFA, and additionally evaluated it against a single factor and a three-factor model. The EFA identified a two-factor model with similar internal consistency and goodness-of-fit across each timepoint. In the CFA, the two- and three-factor models were both superior to the unidimensional model. The two- and three-factor models of the PSQI were reliable, consistent and provided similar goodness-of-fit over time, and both models were superior to the unidimensional measure. We recommend using the two-factor model to assess sleep characteristics in working populations in Singapore, given that it performs as well as the three-factor model and is simpler compared to the latter.

The purpose of the study was to determine the impact of the number of repetitions on the effectiveness of teaching boys aged 15 a cartwheel. Materials and methods. The study participants were 20 boys aged 15. The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. To solve the tasks set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of trainingtasks; pedagogical experiment, methods of mathematical statistics, discriminant analysis. Results. The assumption was made about a significant influence of the modes of alternating exercise repetitions and the rest interval on the effectiveness of motor skills development in boys aged 15. The study found that 6 sets 1 time each with a rest interval of 60 s are more effective than 6 sets 2 times each with a rest interval of 60 s when teaching the ability to assess movement performance by time (p < 0.001). And with the first exercise mode, fewer repetitions are needed to master the entire cartwheel. This is due to the fact that differentiation of time characteristics requires immediate information about the movement performance after each repetition. Conclusions. Based on the analysis of group centroids, it was found that 6 repetitions of the exercise (6 sets 1 time each with a rest interval of 60 s) significantly influence the cartwheel skill development in boys aged 15 during physical education classes. The results of group classification show that 95.0% of the original grouped observations were classified correctly.

The purpose of the study was to determine the structure of motor fitness of 7-year-old girls.  Materials and methods. The study participants were 27 7-year-old girls. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The research methods used in the study include analysis of scientific and methodological literature, pedagogical observations, testing of motor fitness, probabilistic approach to assessing the learning process, methods of mathematical statistics. The study recorded the primary schoolchildren’s level of proficiency in gymnastic exercises. The coefficient was determined by the formula: p = (m/n)×100, where p is the level of proficiency, m is the number of successfully performed exercises, n is the total number of attempts to perform the exercise. In the experiment, the study controlled the level of proficiency in the following exercises: forward roll; backward roll; shoulderstand with bent legs. Results. The level of fitness of the 7-year-old girls is homogeneous by the development of “agility” and “movement coordination”, inhomogeneous – by the development of flexibility, arm strength, and vestibular stability, level of proficiency in gymnastic exercises. The analysis of the coefficients of variation points to heterochrony in the development of the 7-year-old girls’ motor abilities. Based on the data analysis, it can be argued that the development of vestibular stability ensures the formation of motor skills in girls. Based on factor analysis, it was found that the most informative indicators of motor fitness of the 7-year-old girls are the level of proficiency in acrobatic exercises, the results of test No. 7 “Mixed hang rope pull-ups, times” (r = 0.872) and test No. 10 “Maintenance of stable posture – standing on one leg with closed eyes, s” (r = 0.870). Conclusions. Based on factor analysis, it was found that the level of proficiency in exercises determines the variation of testing results by 29.772%, and the development of motor skills is a priority in the educational process at primary school. The development of vestibular stability ensures the formation of motor skills, and the level of general physical fitness is the reserve in training girls aged 7, which will make it possible to increase the effectiveness of the educational process.

This study evaluated competing factor models underlying the Private Self-Consciousness scale (Fenigstein, Scheier, & Buss, 1975) with a large sample of Hong Kong Chinese adolescents. Reliability analysis and exploratory and confirmatory factor analysis did not lend empirical support to the three split-factor models proposed in previous research (Anderson, Bohon, & Berrigan, 1996; Burnkrant & Page, 1984; Martin & Debus, 1999). It was recommended that the original unitary model proposed by Fenigstein et al. should be retained in interpreting scores made on this scale, at least for Hong Kong Chinese adolescents. Possible influences of age and culture on the factor structure of the scale were also discussed.

The purpose of the study was to determine the peculiarities of motor skills development in boys aged 14-15. Materials and methods. The study participants were boys aged 14 (n=20) and 15 (n=20). The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. To solve the tasks set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of training tasks; pedagogical experiment, methods of mathematical statistics, discriminant analysis, nearest neighbor analysis. Results. The study made an assumption about a significant influence of the modes of alternating exercise repetitions and the rest interval on the effectiveness of motor skills development in boys aged 14 and 15. The standardized canonical discriminant function coefficients helped to determine age peculiarities and the peculiarities of influence of exercise modes on the effectiveness of motor skills development. They showed that the components of motor fitness are a priority in developing motor skills. The structure canonical discriminant function coefficients indicate the importance of movement control skills for mastering the entire exercise. Conclusions. Discriminant analysis revealed the peculiarities of motor skills development in boys aged 14 and 15, depending on age and exercise modes. With the first exercise mode, boys aged 15 master the first, second, and fourth series of training tasks more quickly. Boys aged 14 – the sixth series (exercise mode: 6 repetitions, rest interval of 60 s). With the second exercise mode, boys aged 14 master the first and fourth series of training tasks more quickly. Boys aged 15 – the second series (exercise mode: 12 repetitions, rest interval of 60 s). The coordinates of centroids for four groups indicate a significant difference in the influence of exercise repetition modes on the number of repetitions required for motor skills development in boys aged 14-15 during physical education classes. The results of group classification show that 87.5% of the original grouped cases were classified correctly.

The purpose of the study was to determine the place of motor skills in the motor fitness structure of 9-year-old boys.  Materials and methods. The study participants were 48 9-year-old boys. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The study used the following research methods: analysis of scientific and methodological literature, pedagogical observations, testing of motor fitness, probabilistic approach to assessing the learning process, methods of mathematical statistics. In the experiment, the study controlled the level of proficiency in the following exercises: “Rope climbing in two steps”, “Rope climbing in three steps”, “One leg swing upward circle”. Results. The level of fitness of the 9-year-old boys is homogeneous by the development of “agility”, “movement coordination”, “speed strength”, and “endurance”; inhomogeneous – by the development of flexibility, arm strength, vestibular stability, and the level of proficiency in rope climbing. The most informative indicators that determine the level of 9-year-old boys’ motor fitness are: No. 12 “Rope climbing in two steps, level of proficiency” (r = 0.960); No. 13 “Rope climbing in three steps, level of proficiency” (r = 0.960); No. 14 “One leg swing upward circle, level of proficiency” (r = 0.875); No. 10 “Maintenance of stable posture – standing on one leg with closed eyes, s” (r = 0.683). Conclusions. Based on factor analysis, it was found that the level of proficiency in the exercises determines the variation of testing results by 24.287%, and the development of motor skills is a priority in the educational process at primary school. The level of proficiency in rope climbing shows that the exercises are difficult for 9-year-old boys to perform. Based on the data analysis, it can be argued that the comprehensive development of motor abilities ensures the formation of motor skills, and the improvement of the level of development of 9-year-old boys’ arm flexors will positively influence the educational process effectiveness.
