Abstract The aim of this study was to evaluate the use of a non-wearing time activity diary (hereafter non-wear activity diary) when using accelerometry in adolescents to provide insight into their physical activity levels. In total, 213 Belgian adolescents (89 boys, 124 girls) were eligible for this study. Adolescents wore an accelerometer for seven consecutive days and kept a non-wear activity diary. On the last day, they completed the International Physical Activity Questionnaire for Adolescents. The differences between the accelerometer data with and without use of the non-wear activity diary were significant for all physical activity intensities according to the Wilcoxon signed rank test. Bland-Altman plots showed that with more time spent in any physical activity intensity, the difference between including and not including the non-wear activity diary increased. The correlation coefficient between the International Physical Activity Questionnaire for Adolescents and the accelerometer data increased when the non-wear activity diary was included. Differences in the percentage of adolescents reaching the physical activity recommendations between the accelerometer data only and the accelerometer with the non-wear activity diary were significant. We conclude that if the non-wear activity diary data are not included, some adolescents could be misclassified as not being physically active according to the physical activity recommendations. It is therefore recommended to use a non-wear activity diary for gaining insight into the physical activity levels of individuals. 相似文献

Neuroanatomy is difficult for psychology students because of spatial visualization and the relationship among brain structures. Some technologies have been implemented to facilitate the learning of anatomy using three-dimensional (3D) visualization of anatomy contents. Augmented reality (AR) is a promising technology in this field. A mobile AR application to provide the visualization of morphological and functional information of the brain was developed. A sample of 67 students of neuropsychology completed tests for visuospatial ability, anatomical knowledge, learning goals, and experience with technologies. Subsequently, they performed a learning activity using one of the visualization methods considered: a 3D method using the AR application and a two-dimensional (2D) method using a textbook to color, followed by questions concerning their satisfaction and knowledge. After using the alternative method, the students expressed their preference. The two methods improved knowledge equally, but the 3D method obtained higher satisfaction scores and was more preferred by students. The 3D method was also more preferred by the students who used this method during the activity. After controlling for the method used in the activity, associations were found between the preference of the 3D method because of its usability and experience with technologies. These results found that the AR application was highly valued by students to learn and was as effective as the textbook for this purpose. 相似文献

What is the better predictor of students’ personal values: Parents’ values or students’ personality?
This study examines the relationship between young adults’ values, multicultural personality traits and their parents’ values. A total of 102 students and their matched parents filled in the Multicultural Personality Questionnaire and the Portrait Value Questionnaire. The influence of one's personality and one's parents’ values on personal values was tested by hierarchical regression analyses and structural equation modelling. The analyses revealed a greater contribution of multicultural personality to the variance in stimulation, self-direction, universalism, and achievement values in comparison to the impact of parents’ values, whereas an opposite pattern was found for power, benevolence, and conformity. Tradition, hedonism, and security were found to be linked to multicultural personality and parents’ values to a similar extent. Furthermore, overall trait-like parents’ values were better predictors of the offspring's trait-like values, and the same effect held for parental societal values: they predicted better the offspring's societal values. The authors discuss the need for differentiation between trait-like and societally oriented values and the application of content-tailored personality measures, in line with previous studies. 相似文献

The aims of this study were to determine the distribution of the AMPD1 genotype among groups of high-level Polish power-oriented athletes, and to investigate potential associations between genetic polymorphism in exon 2 of the AMPD1 gene and power-oriented athlete status. Altogether, 158 male Polish power-oriented athletes were genotyped by PCR-RFLP. The genetic control group comprised 160 unrelated male volunteers. We observed significant differences in genotype distribution when all 158 athletes (89.25% CC, 10.75% CT, 0.00% TT; P = 0.0025) were compared with controls (75.00% CC, 23.75% CT, 1.25% TT). A significant deficiency of the T allele was noted in all subgroups (short-distance runners: 5.21%, P = 0.032; short-distance swimmers: 5.56%, P = 0.031; weightlifters: 5.36%, P = 0.024) compared with controls (13.13%), while this trend was even stronger when the frequency of the T allele was compared between controls and all 158 athletes (5.38%, P = 0.0007). Our results indicate a lower frequency of the AMPD1 exon 2 T34 allele in elite Polish power-oriented athletes. Our data suggest that the C allele may help athletes to attain elite status in power-oriented sports. 相似文献

The aim of the study was to conduct a comparative analysis of three forms of knowledge transfer online, taking into account the long-term knowledge growth rate and the satisfaction of students surveyed in respect to distance learning. The cohort of participants for this survey were students of the first degree, studying in the Emergency Medical Services. The authors created three e-learning courses in basic and advanced resuscitation procedures. The level of course participants’ satisfaction was analysed, as well as the knowledge growth rate measured three times: 7, 30 and 90 days, respectively, after finishing the course. The level of satisfaction in all the groups surveyed was comparable. The growth rate for knowledge was the highest in group C in the second and third survey, respectively (30 and 90 days after the end of the course), and a significant difference in favour of course C was demonstrated one month after finishing classes. 相似文献

The results of qualitative and quantitative investigations conducted with individuals who learned algorithms in school are presented in this article. In these investigations, eye-tracking technology was used to follow the process of solving algorithmic problems. The algorithmic problems were presented in two comparable variants: in a pseudocode and flowchart. The eye-tracking data resulted in both qualitative (films registering the gaze paths) and quantitative measures, which allowed the detection and interpretation of the differences in the task-solving strategies between those who found the correct answer and those that did not. The results confirmed a hypothesis that use of the formal notation characteristic of a programming language for presenting algorithms is often a practical difficulty in the process of solving even simple tasks. This study opens a new direction of research; they show that eye-tracking technology can be used to optimise the educational process of learning programming. 相似文献
