Research on the design and application of "MOOC + flipped classroom" for basketball courses in colleges and universities from the perspective of education modernization.

Background: The wave of education information based on the "Internet+" has swept the world, and the traditional teaching mode can no longer meet the new needs of education teaching, so the teaching mode of "MOOC+ flipped classroom" has attracted widespread attention educators. Objective: This study explores the effect of "MOOC+ flipped classroom" on the teaching design and application of basketball courses in colleges and universities from the perspective of education modernization in order to promote the development of students' core literacy and provide a more theoretical basis and practical support for the in-depth research and promotion of "MOOC+ flipped classroom" teaching mode. Methods: This study adopts a quasi-experimental design to study the teaching of basketball courses in colleges and universities based on "MOOC +flipped classroom." The experimental class adopted "MOOC+ flipped classroom" teaching (34 students), and the control group adopted traditional classroom teaching (30 students). Before and after the 16-week intervention, the student's learning effects were measured by basketball skill level assessment, Cooperation Ability Scale for University Students, Utrecht Work Engagement Scale-student, and Self-regulated Learning Scale, and the data were analyzed by independent sample t-test and repeated-measures ANOVA. Conclusion: (1) Compared with the traditional classroom teaching mode, the "MOOC+ flipped Classroom" teaching mode is innovative in terms of teaching philosophy, teaching resources, and teaching methods, which promotes the change of education informatization and further promotes the realization of education modernization. (2) The "MOOC+ flipped classroom"-based teaching design for basketball courses benefits students' basketball skill level, study engagement, cooperation ability, and self-regulated learning ability, thus effectively promoting the students' core literacy.

The influence of "small private online course + flipped classroom" teaching on physical education students' learning motivation from the perspective of self-determination theory.

Objective: The study aimed to enhance the learning motivation of college physical education students and improve their learning outcomes. Based on the perspective of the self-determination theory, this study explores the influence of "Small Private Online Course (SPOC) + flipped classroom" teaching on the learning motivation of students majoring in physical education and profoundly analyzes the influencing factors and promotion paths of learning motivation using this model. Materials and methods: A total of four classes (64 students) of physical education majors in a university were selected and randomly divided into an experimental group (34 students) and a control group (30 students). The experimental group received "SPOC + flipped classroom" teaching, the control group received traditional teaching. Before and after the 16-week intervention, learning motivation, teacher support perception, basic psychological need satisfaction, and academic emotions of the 64 students were measured, and the data were analyzed by repeated-measures analysis of variance and partial least square regression. Results: (1) The instructional intervention reduced non-regulation, external regulation, and introjected regulation, while increased identified regulation, intrinsic regulation, and self-determination levels in the students. The levels of non-regulation, external regulation, identified regulation, and self-determination were also significantly different from those of the control group. (2) After the intervention, the scores of support for autonomy, support for competence, support for relatedness, and need for relatedness in the experimental group were significantly higher than those in the control group. (3) Support for autonomy, support for competence, support for relatedness, need for competence and need for relatedness positively predicted the self-determination level, and intrinsic regulation and identified regulation negatively predicted non-regulation, external regulation, and introjected regulation. Conclusion: "SPOC + flipped classroom" teaching has a positive impact on students' learning motivation of basketball skills and promotes students' motivation autonomy. The improvement of support for autonomy, support for competence, support for relatedness, need for competence, and need for relatedness may be related to the improvement of learning motivation of college students majoring in Physical Education (PE). "SPOC + flipped classroom" teaching enables students to obtain more demand satisfaction by giving them more demand support, while demand support and demand satisfaction can promote the internalization of learning motivation so that students can maintain high autonomy motivation.

Effect of Cognitive Reappraisal on Archery Performance of Elite Athletes: The Mediating Effects of Sport-Confidence and Attention.

Through empirical studies or laboratory tests, previous studies have shown that sport-confidence, attention, and emotion regulation are key factors in archery performance. The present study aims to further identify the effects and pathways of sport-confidence, attention, and cognitive reappraisal (a specific emotion regulation strategy) on real-world archery performance by constructing a hypothesized model to provide a basis for scientific training of athletes to improve sport performance. A survey design was utilized on a sample of 61 athletes (12 international-level athletes, 30 national-level athletes, and 19 first-class athletes) from the Chinese National Archery Team to test the model. The measurement and hypothesized models were tested using partial least squares structural equation modeling (PLS-SEM). The results indicate that the model fit well and explained 33.6% of the variance in archery performance. Sport-confidence (total effects = 0.574, p < 0.001) and attention (total effects = 0.344, p = 0.009) were important predictive indicators of archery performance, while the relationship between cognitive reappraisal and archery performance showed considerable complexity (direct effects = -0.268, p = 0.020; total effects = -0.007, p = 0.964). We conclude that the development of sport-confidence and attention of archery athletes should be strengthened, but athletes who use cognitive reappraisal in archery competition should be mindful of its potential appropriation of cognitive resources and should be directed to improve sport-confidence or develop a positive orientation to arouse excitement.

Novel Biallelic DNAH1 Variations Cause Multiple Morphological Abnormalities of the Sperm Flagella.

Sperm motility is vital to human reproduction, and malformed sperm flagella can cause male infertility. Individuals with multiple morphological abnormalities of the flagella mostly have absent, short, coiled, bent, and/or irregular-caliber flagella. In this study, a patient with male infertility underwent a physical examination along with his wife. Genetic testing was performed by whole-exome sequencing of the couple, and Sanger sequencing was performed for validation. Novel biallelic variations in the DNAH1: (NM_015512.4) gene consisting of c.1336G>C (p.E446Q) and c.2912G>A (p.R971H) were identified. In silico structural analysis revealed that the amino acid residues affected by the variation were evolutionarily conserved, and the variant p.R971H influenced the stability of the DNAH1 protein. Morphological studies of the patient's sperm showed defects in its flagella. Results of Papanicolaou staining and scanning electron microscopy demonstrated coiled and short flagella with multiple anomalies. Transmission electron microscopy of the sperm flagella showed that the inner dynein arm and radial spoke were absent, and the dense fiber and microtubule doublets were displaced. Quantitative PCR of the mRNA of the patient's sperm showed that the expression of DNALI1 was dramatically reduced. Collectively, these findings elucidated the genetic cause of the family's infertility and provided insight into the functioning of the DNAH1 gene.

Adapting the short form of the Coping Inventory for Stressful Situations into Chinese.

OBJECTIVES: The Coping Inventory for Stressful Situations (CISS) is a measurement tool for evaluating stress that has good psychometric properties. We investigated the applicability of a short-form version of the CISS in a large sample of Chinese university students. METHODS: Nine hundred and seventy-two Chinese university students aged 18-30 years (mean =20.15, standard deviation =3.26) were chosen as subjects, of whom 101 were randomly selected to be retested after a 2-week interval. RESULTS: The results of a confirmatory factor analysis revealed that the root mean square error of approximation of a four-factor model was 0.06, while the comparative fit index was 0.91, the incremental fit index was 0.93, the non-normed fit index was 0.91, and the root mean residual was 0.07. The Cronbach's α coefficients for the task-oriented, emotion-oriented, distraction, and social diversion coping subscales were 0.81, 0.74, 0.7, and 0.66, respectively. The 2-week test-retest reliability was 0.78, 0.74, 0.7, and 0.65 for the task-oriented, emotion-oriented, distraction, and social diversion coping subscales, respectively. In the Chinese version of the CISS short form, task-oriented coping was positively correlated with positive affect and extraversion and negatively correlated with neuroticism; emotion-oriented coping was negatively correlated with extraversion and positively correlated with negative affect, anxiety, and neuroticism; distraction coping was positively correlated with neuroticism, extroversion, anxiety, positive affect, and negative affect and negatively correlated with psychoticism; and social diversion coping was positively correlated with extroversion and positive affect and negatively correlated with psychoticism. CONCLUSION: The Chinese version of the CISS short form is satisfactorily valid and reliable among Chinese university students.
