RÉSUMÉ
Objective:To explore the distinctions between different educational levels: stability of learning state, views on and demand for online courses, and further investigate the influencing factors.Methods:A self-designed questionnaire with good reliability and validity was conducted, and all the students in a military medical university were selected by cluster sampling method, and the data were collected by issuing a network questionnaire. SPSS 26.0 was used for data processing.Results:Undergraduates were different from graduates and doctoral students in stability of learning state, the period of home study: doctoral students (2.41±1.30) h < graduates (2.10±1.17) h and undergraduates (2.15±0.99) h; the frequency of using online courses: undergraduates (4.18±1.10) times > graduates (3.29±1.16) times and doctoral students (3.29±0.98) times. In terms of views on online courses, necessity: undergraduates (4.14± 1.01) > graduates (3.93±1.05) and doctoral students (3.78±1.03); familiarity: undergraduates (3.42 ± 0.91) > graduates (3.27±0.97); adaptability: undergraduates (3.79±0.91) > graduates (3.58±0.94) and doctoral students (3.63±0.97); likability: undergraduates (3.36±1.04) > undergraduates (3.25±0.96) and doctoral students (3.17 ± 1.01); teaching effect: undergraduates (2.80±1.04) > graduates (2.67±1.01) and doctoral students (2.61±1.03). In terms of demand for online courses, ideal number: undergraduates (2.52±1.27) > graduates (2.11±1.21) and doctoral students (2.01±1.25); class style: undergraduates (1.77±0.94) > graduates (2.00±0.92) and doctoral students (2.04±1.83). There were statistically significant differences between undergraduates and postgraduates in all dimensions ( P<0.01 or P<0.05). Conclusion:Undergraduates may be more susceptible to academic environment than graduates and doctoral students, showing that the learning stability of undergraduates is the relatively the worst. Undergraduates most recognize online courses, and different educational levels have different demands for online courses.
RÉSUMÉ
Objective To research the reliability and validity of resilience scale for adults(RSA)in military students.Methods RSA, depression, anxiety and somatization of Self-report Symptom Checklist 90(SCL-90)were applied in this survey to 616 military students.Results ①A 5-factor structure of resilience was showed by explorative factor analysis.Each item had a factor loading between 0.423～0.834, and the total variance explained at 58.439%.②The correlations between the subscales of the RSA were all obvious positive, ranging from 0.228～0.580；and the correlations between subscales of the RSA and total resilience were all obvious positive, ranging from 0.565～0.789.③There was a obvious negative correlation between total depression, anxiety and somatization and total resilience, the correlation coefficient was-0.437(n=593, P=0.000).④Tbe reliability coefficient of the RSA was 0.91, and the respective dimensions had Cronbach's alphas between 0.52～0.86.Conclusion The results show that RSA has acceptable reliability and validity in military students.
