PolyU research reveals significant effects of instructors onscreen during video classes in aiding student learning

Online learning has become “the new normal” of education since COVID-19 severely disrupted face-to-face teaching activities. Researchers from The Hong Kong Polytechnic University (PolyU) have conducted a study to analyse whether and how the instructor’s presence in online video lectures affected student learning and learning outcomes. The results reveal that students are more motivated to perform socio-emotional and cognitive processing when an instructor, human or animated, is present onscreen, hence facilitating more effective learning. The study findings have been published in the journal Proceedings of the National Academy of Sciences. Previous studies have indicated that socio-emotional cues, such as human facial expressions and gestures, help students understand and stay focused on learning content. Led by Prof. Ping LI, Dean of the Faculty of Humanities and Sin Wai Kin Foundation Professor in Humanities and Technology at PolyU, the research team studied how learners respond to virtual learning with different types and levels of interaction by examining multimodal data of students’ learning performance, brain activity and eye movement, as well as the correlation between these measurements. Eighty-one PolyU students participated in the experiment where some of them watched video lectures with a human instructor accompanying the lecture slides, some watched the same video lectures with an animated instructor, and still some watched the lectures with no onscreen instructor and only the lecture slides. This was followed by a set of assessments of how effectively they had learned. Compared with the no-instructor group, students with an onscreen instructor performed significantly better in the post-course assessments, while the exact embodiment of the instructor—real vs animated—did not affect the overall scores. The results provide strong and important evidence that the instructor’s image, human or animated, improves educational outcomes in the virtual setting. The researchers examined the impact of instructor’s image on learning through a combination of functional magnetic resonance imaging (fMRI) and eye-movement tracking of the students as they watched the lectures. While students with an instructor performed better, the eye-tracking results, surprisingly, showed that the human instructor may actually distract the students from the slides, as more time was spent by students looking at the slides when the instructor was absent or was an animation. A deeper analysis of the eye-tracking data resolved this contradiction. Crucially, the correlation of eye movements—the extent to which the students shifted their gaze in unison—was higher in instructor-present groups than in the no-instructor group, and better-performing students also displayed more correlated eye movements than the lower performers. This suggests that although an instructor’s image may distract students from the slides, it is also more likely in guiding them to pay attention to the appropriate parts of the onscreen content. In other words, students with an instructor tend to focus on the same places, while those without an instructor are more random in their focus. The fMRI results, which identified the specific brain regions students used most, aligned with the eye-tracking data. Just as their eye movements were synchronised, so did the students with an instructor show greater synchrony in the activity of brain regions crucial for learning, including regions involved in working memory and mentalising. This alignment can be attributed to the higher level of cognitive and socio-emotional processing motivated by the onscreen instructor that served as a social cue. Under this condition, learners follow the visual content in the video more closely, allocate attention more proactively and ultimately learn better. As the data suggest that an onscreen instructor’s image entails both socio-emotional benefits and attentional distraction unrelated to learning, the researchers further propose a trade-off hypothesis suggesting learning outcome depends on whether the benefits can outweigh the costs brought by the distraction. While the trade-off also relies on a learner’s ability to leverage socio-emotional processing and attention control for learning, it explains the individual difference in student learning under the same virtual setting. Prof. Li remarked, “Although the pandemic has subsided, online learning through the use of multimedia instructional videos continues to shape education. Our findings suggest that an onscreen instructor—even an animated one—can make up for some deficits of the online learning setting, where socio-emotional cues are less salient and cognitive engagement is harder to sustain. This contributes to the development of an evidence-based instructional design for multimedia learning, thereby enhancing student’s learning experience and outcome.”

PolyU supports HKMA launching ‘Project Ensemble’: a new wholesale central bank digital currency project

The Hong Kong Monetary Authority (HKMA) has announced the commencement of Project Ensemble, a new wholesale Central Bank Digital Currency (wCBDC) project to support the development of the tokenisation market in Hong Kong. Since the establishment of the CBDC Expert Group, along with other members, two PolyU professors of the Department of Computing have been closely collaborating with HKMA to examine various aspects of CBDCs and related digital currencies, such as interoperability, security, and privacy. The new project will seek to explore innovative financial market infrastructure (FMI) that will facilitate seamless interbank settlement of tokenised money through wCBDC. The Project will initially focus on tokenised deposits, which are a digital representation of commercial bank deposits, issued and made available by commercial banks. At the core of Project Ensemble is a wCBDC Sandbox that the HKMA will launch this year to further research and test tokenisation use cases including settlement of tokenised real-world assets (e.g. green bonds, carbon credits, aircraft, electric vehicle charging stations, electronic bills of lading and treasury management). This could potentially forge a new FMI that bridges the existing gap between tokenised real-world assets and money in transactions. To help set industry standards and a future-proof strategy, the HKMA will form a wCBDC Architecture Community comprising local and multinational banks, key players in the digital asset industry, technology companies and the CBDC Expert Group. Prof. Allen Man Ho AU and Prof. Daniel Xiapu LUO, Professors of the Department of Computing and founding members of the CBDC Expert Group, have been working in collaboration with HKMA on ongoing projects to advance the development of CBDC in Hong Kong. Their aim is to integrate advanced privacy designs that protect consumers’ personal identifiable information, while maintaining a balance between privacy and traceability. They will maintain close collaboration with HKMA and fellow expert group members, aiming to foster the tokenisation market and draw talents to Hong Kong. Prof. H.C. MAN, Dean of the Faculty of Engineering, said, “This partnership with HKMA is a testament to our commitment to fostering innovation and technological progression, advancing the digital finance landscape in Hong Kong. We are leveraging our expertise to support the launch of this Project Ensemble and look forward to the potential breakthroughs that will, with the introduction of the wCBDC sandbox, shape the digital asset market.” Prof. Qing Li, Head of the Department of Computing, stated, “The exploration of wCBDC and tokenisation of assets is a critical step towards a future-proof financial infrastructure. Our department is pleased to contribute our expertise to this pioneering initiative.” Prof. Allen Au and Prof. Daniel Luo said, “wCBDC and digital assets are a significant step towards the future of finance and FinTech innovation, while the tokenisation of currency and assets is a global trend that we cannot ignore. Through this initiative, we are dedicated to playing a role in fostering the development of a robust digital asset ecosystem in Hong Kong.”
