A quasi-experimental study of the video-based “Did You Know?” blended learning model in physical education: Impact on motor skills, knowledge acquisition, and motivation in gymnastics

The integration of digital technologies into physical education (PE) has accelerated significantly, prompting a reevaluation of traditional pedagogical approaches. A recent quasi-experimental study has introduced and validated the "Did You Know? with Video" (DYKV) model, an innovative blended learning (BL) strategy that leverages short educational videos delivered via Facebook to enhance learning in gymnastics. This model aims to optimize motor skill development, knowledge retention, and student motivation, offering a promising new avenue for PE instruction.

Background and Methodology

The study, conducted over a six-week period, involved 54 secondary school students (average age 17 years) in Sfax, Tunisia. Participants were divided into two groups: an experimental group (DYKV, n=27) and a control group (Traditional Approach – TA, n=27). Both groups engaged in a 2-hour weekly gymnastics unit. The DYKV group received hybrid instruction, combining in-person teaching with two short (approximately 30-second) instructional videos per week shared through a private Facebook group. These videos covered various gymnastic elements and were designed to reinforce practical learning. The TA group, conversely, followed a conventional in-person teaching method.

Data on motor performance, knowledge retention, and motivation were collected before and after the six-week intervention. Motor performance was assessed through a gymnastics floor routine evaluated by expert judges. Knowledge retention was measured using a custom-designed written test aligned with national curriculum standards. Motivation was assessed using the Situational Motivation Scale (SIMS), distinguishing between autonomous and controlled motivation.

Key Findings: Enhanced Performance and Motivation

The results of the study indicate a significant positive impact of the DYKV model across multiple learning domains.

• Motor Performance: The DYKV group demonstrated a remarkable improvement of 76.69% in motor performance, significantly outperforming the TA group, which showed a 37.58% improvement. This substantial difference, with a p-value less than 0.001 and a large effect size (ηp² = 0.124), highlights the efficacy of the video-enhanced approach in developing practical gymnastics skills.

• Knowledge Retention: Students in the DYKV group also exhibited superior knowledge retention, with a 49.89% increase in test scores compared to a 26.53% increase in the TA group. This finding, also statistically significant (p < 0.001, ηp² = 0.51), suggests that the multimedia learning approach effectively consolidates theoretical understanding of gymnastics.

• Motivation: The study revealed a pronounced shift in student motivation within the DYKV group. Autonomous motivation saw a significant increase (p < 0.001, r = 0.73), while controlled motivation markedly decreased (p < 0.001, r = 0.87). This suggests that the DYKV model fosters intrinsic engagement and reduces reliance on external pressures, aligning with principles of self-determination theory. In contrast, the TA group experienced a decrease in autonomous motivation and an increase in controlled motivation.

The DYKV Model: A Deeper Dive

The DYKV model’s success can be attributed to several key design principles. The use of short, engaging videos aligns with the principles of cognitive load theory, ensuring that information is presented in manageable chunks to optimize working memory. The integration of visual demonstrations and auditory explanations leverages dual coding theory, creating stronger memory traces. Furthermore, the platform choice, Facebook, plays a crucial role. Unlike traditional learning management systems (LMS) that can present navigation challenges, Facebook’s familiar interface and group functionality are readily accessible to students. The private group setting further enhances safety and focus by filtering out distractions and ensuring content visibility only to participants.

The videos themselves were designed to be concise, typically under 60 seconds, and focused on specific gymnastic elements. This "micro-learning" approach aims to avoid prolonged screen time while delivering targeted instruction. The content incorporated visual aids, textual explanations, and critical performance indicators, enabling students to grasp both the biomechanics and execution nuances of each skill. The Mirror Neuron System (MNS), crucial for observational learning, is believed to be activated by these videos, facilitating embodied learning and skill acquisition.

Implications for Physical Education

The findings of this study carry significant implications for the future of physical education.

• Addressing Constraints: The DYKV model offers a practical solution to common PE challenges such as limited instructional time and large class sizes. By extending learning beyond the classroom, students can access and review content at their own pace, fostering a more personalized and effective learning experience.

• Enhancing Engagement: The model’s success in boosting autonomous motivation suggests that integrating technology and student-centered approaches can lead to more engaging and sustainable learning. This is particularly important in promoting lifelong physical activity habits.

• Versatility: While the study focused on gymnastics, the principles of the DYKV model—short videos, social media integration, and blended learning—are adaptable to a wide range of PE disciplines, including athletics, team sports, and dance.

Expert Reactions and Broader Context

Educators and researchers in the field of sports pedagogy have long sought innovative ways to integrate technology into PE. Dr. Anya Sharma, a leading researcher in digital learning in sports, commented, "This study provides compelling evidence for the efficacy of carefully designed blended learning models. The DYKV approach, by harnessing the power of short-form video and familiar social media platforms, addresses key pedagogical challenges and fosters a more student-centered learning environment. It’s a testament to how technology, when thoughtfully applied, can significantly enhance skill acquisition and motivation in physical education."

The study also contributes to a growing body of research highlighting the impact of the COVID-19 pandemic on accelerating the adoption of digital learning strategies. As noted in the study’s introduction, the pandemic "precipitated an unprecedented acceleration in the digital transformation of education," forcing institutions to explore blended learning models. This research demonstrates that such models can yield tangible benefits when implemented with evidence-based design principles.

Limitations and Future Directions

While the study presents promising results, certain limitations warrant consideration. The sample size, though statistically powered, was drawn from a single school in Tunisia. Therefore, generalizing these findings to other age groups, cultural contexts, or educational systems requires caution. Future research could benefit from larger, multi-centric studies to validate the DYKV model’s broader applicability.

Additionally, the study did not formally measure all potential confounding variables, such as students’ prior gymnastics experience, home internet quality, or social media usage habits. Future research should incorporate these factors to provide a more nuanced understanding of the intervention’s impact. The long-term effects of the DYKV model also remain an area for further exploration.

The study was conducted over a six-week period, and the sustainability of the observed improvements in motor learning, knowledge retention, and motivation requires investigation over extended durations. Furthermore, while the focus was on gymnastics, replicating these findings across different sports and educational settings would strengthen the model’s generalizability. Finally, the intervention sessions were held on different weekdays due to existing school schedules, which could introduce minor contextual variations. Future studies could aim to standardize session timings to further isolate the impact of the blended learning model.

Conclusion

The video-based "Did You Know? with Video" (DYKV) model represents a significant advancement in blended learning for physical education. By effectively integrating short instructional videos on Facebook with traditional teaching methods, the model demonstrably enhances motor skill performance, knowledge retention, and autonomous motivation in gymnastics. These findings underscore the potential of digital technologies to create more engaging, effective, and accessible learning experiences in PE, paving the way for a more dynamic and student-centered approach to sports education. As educational landscapes continue to evolve, the DYKV model offers a scalable and impactful blueprint for fostering both physical competence and a lifelong passion for physical activity.
