Abstract

Background: Led by Hong Kong Baptist University in collaboration with the University of Hong Kong, the project initiated the first-of-its-kind non-conventional simulation practicum in a realistic setting using Virtual Reality(VR) technology. Aim: The aim is to enhance students’ first-hand experiences with TCM diagnosis and consultations, thereby optimize the effectiveness of service-learning and equip students with necessary attributes such as self-learning ability and communication skills as future practitioners. Method The project encompassed (1)scriptwriting for VR development, (2)VR application with debriefing sessions held to explain the rationales of diseases and relevant physical examinations(PE) to students, and (3)skills contribution in service-learning. Numerical data was obtained through pre and post VR survey for analysis. The statistical test used was Wilcoxon signed-rank test, a paired difference test for comparing the pre-post scores of two matched samples. Post-VR focus group interviews were conducted to collect students’ views on the pros and cons of VR. Evaluation results Quantitatively, 51students completed the VR activity and responded the pre and post VR survey. Under 10-mark scoring scale with 10 as the largest extent, students’ self-evaluation on professional knowledge improved significantly. The medians of the mastery of diagnostic criteria, typical symptoms and physical examinations all increased from 6 to 7 with p<0.001. Students’ self-learning ability, understanding towards consultation procedures, technique in verbal consultation and skills in communicating with patients elevated from 6 to 7 in median, with p-values of 0.009,<0.001,<0.001 and p<0.05 respectively. Qualitatively, students mentioned in focus group that they got insights on the choices of physical examinations to be done in service-learning through VR. Yet, some students reported dizziness and nausea caused by VR headsets as the main barrier of the project, making it inapplicable to all students. Conclusion: This innovative approach is proven to improve clinical knowledge, foster self-learning ability, and develop generic attributes of students.

Abstract

Effective Content and Language Integrated Learning (CLIL) praxis relies on the sustained efforts of members of the interdisciplinary community of practice in fostering shared aspirations in pedagogical improvement, developing awareness of a content-language link, sharing resources and practices, and co-constructing understanding of disciplinarity. Responding to the need to align higher education assessments with the real-world communication and professional requirements, faculty members across the College are summoned to redesign the assessments of language and disciplinary practices. While previous studies on integrated assessment of language and disciplinary content focus on the validity, reliability and teacher belief-practice dichotomy (Attar et. al, 2022; Lo & Leung, 2022; Otto, 2018), this paper explores the essence of successful Professional Communities of Practice (PCoP). Sustainable practices and challenges associated with co-designing integrated content and language assessments in business and social sciences disciplines will be explored. It positions CLIL assessment as a collaborative provision. The first part details the associated practices of a collaborative model in an adjunct English-across-the-curriculum project. The second part highlights the impactful dialogues within a social enterprise business idea pitching competition organised to foster interdisciplinary collaboration in a professional learning community. Recommendations for optimising collaboration and maximising the participatory impact of interdisciplinary communities of practice in higher education contexts will be shared.

Abstract

Our ten years’ evidence-based study revealed that the alternative pathway from sub-degree to degree studies is viable while challenging for Senior Year Admission (SYA) students. The inadequate alignment between sub-degree and university programmes is the main determinant of their heavy academic workload. Their transitional challenges call for an examination of the existing programme articulation process and academic advising to SYA students. In response to their needs, the project sustains our previous work from UGC-funded and TDG sustainability projects to promote best practices to support SYA students. An online Cross Institutional Credit-transfer Information System (CICIS) was launched to enhance the transparency of credit transfer and facilitate smooth transition of SYA students. Another student-centred Resources Website was developed to provide cross-institutional support to SYA students from the first point of transferring to universities. In addition, a series of collaborative activities, such as an international Credit Transfer Conference, local and overseas webinar sessions and the Internationalisation-at-Home (IaH) programme, has been organised. The project provides implications to administrators and policy makers in higher education, informing policies and practices to optimize the transfer experience for students’ greater success in universities and in the society.

Abstract

Talent development in innovation and technology is key to the sustainable development of a vibrant economy. STEM education plays a vital role in nurturing a globally competitive workforce for the future. Fostering STEM literacy at the early stages of education will equip students with the core knowledge and interdisciplinary skills for creative innovation and contributing to the future economy. Conventional education is often discipline-focused with a tendency to employ linear learning strategies which do not fully explore the knowledge opportunities present in the interdisciplinary STEM content. This often results in a skewed emphasis on technical content which young students may find difficult to contextualise in daily life. The reflective and adaptive nature of design may serve as an effective bridge to connect creativity and knowledge seeking in STEM domains (Toomey and Tan, 2018). A design-led STEM framework was adopted in two Quality Education Fund projects, reaching over 1000 secondary school students. These projects utilized fashion, artificial intelligence, and e-textiles as mediums to help students develop problem solving skills with real world applications.

Abstract

Graduate attributes (GAs), formally adopted by higher education institutions for some time, describe the skills and competences that students should develop over the course of their studies. GAs are considered important to universities as they act as a means to represent and extend their brand, while also providing a channel to maintain connection with industry. However, despite regular engagement with industry, employers remain unsatisfied with graduate transferable skills. This may be caused by a lack of a common theoretical underpinning to develop such attributes. Therefore, the aim of this study was to provide an evidence-based methodology which develops transferable skills in university graduates. Two classes were used in this study; one class received a 12-week intervention incorporating a variety of coaching activities. The second class acted as a control group. Students completed pre-intervention surveys providing self-reports of ratings in GAs and resourcefulness behaviours. Post-intervention, students again complete surveys reporting self-ratings on the same topics. Survey data was analysed to identify changes in student scores, which highlighted improvements in all graduate attribute ratings post-intervention. Furthermore, help-seeking behaviours were shown to have significant improvement post-intervention. This study suggests that coaching practices may provide an effective method to develop transferable skills in students.

Abstract

A large number of students enrolled in sub-degree programmes and self-financing degree programmes in self-financing post-secondary institutions each year. As such, self-financing post-secondary institutions perform a significant role in the higher education sector in Hong Kong. To the best of the author’s knowledge, most of the students are eager to achieve whole-person development to equip themselves before graduation. In other words, they strive toward becoming a preferred graduate to establish a career path or articulate to the ‘desirable’ universities for further study. This study illustrates the Student Affairs Office to address the key challenges of developing whole person development programme, deliver successful cases of the formation of a structured whole-person development programme, and point out the roadmap to the future whole-person development programme in the forthcoming years. As expected, the study may provide valuable insights to policymakers, educators, higher education institutions, and researchers to develop a future research agenda and policy.

Abstract

The learning and teaching of science and/or engineering subjects face a big challenge under the COVID-19 pandemic because all face-to-face laboratory works are suspended. Since laboratory works are essential and critical elements to science and engineering education. Teachers have tried other means to relief the effect by performing demonstration, simulation or virtual laboratory, such that experimental data can be collected for analysis afterwards. However, students commented that they cannot see and control the laboratory apparatus in “real” time. Besides, students are required to conduct experiments in a fixed schedule and usually the teaching and laboratory schedules are not synchronized, due to the limited laboratory equipment and space. Students are required to conduct the experiment before the teaching of the corresponding theory. This affects their learning experience and motivation. The proposed project aims to develop a web-based remote laboratory for science and engineering education to facilitate student independent learning and enhance their learning experience. The objectives of the project are to: (1) design the infrastructure and software specification of the remote laboratory system; (2) identify experimental sets that can be conducted remotely; (3) enhance student learning experience and engagement as “real time” operation of laboratory equipment individually or in a group at anytime and anywhere under safe and controlled environment; (4) reduce the initial investment on offering science and/or engineering programmes by other local institutions for a better development of the sector; (5) enhance collaboration between local and even overseas institutions by sharing experimental sets; (6) inspire the tertiary education sector to develop blended and online teaching modules for science and engineering subjects which required laboratory works.

Abstract

The COVID-19 pandemic has highlighted the critical importance of online learning, where learners must engage in self-regulated learning (SRL) to achieve optimal outcomes. Gamification interventions have been implemented to improve SRL engagement in online environments, but the mixed results of these efforts have raised doubts about their efficacy. This study investigates whether the inconsistent findings can be attributed to a lack of consideration for individual learner characteristics during gamification design. Focusing on Massive Open Online Courses (MOOCs), we examined how gamified performance feedback interacted with learners’ goal orientation, an individual trait known to influence SRL and learning. By tracking the SRL engagement of 760 college students over five weeks using learning analytics, we found that positively framed performance feedback without social comparisons increased SRL engagement and learning outcomes for participants with a strong performance-avoidance goal orientation. Conversely, the same feedback had a negative impact on participants with a strong mastery goal orientation. These findings contribute to SRL theory by demonstrating that the effectiveness of gamification in online learning is contingent on aligning the design elements with individual learner characteristics and highlight the importance of personalized gamification approaches to optimize SRL and learning in MOOC.

Abstract

Students in Hong Kong have generally been perceived as passive learners, with limited opportunities for active involvement in the development of educational experiences. Here, we would like to showcase the untapped potential of students as co-creators in subject development. By harnessing the power of Student-Staff Partnership (SSP), teachers can unlock the full potential of students, creating a dynamic and enriched learning environment that benefits both the students involved and future cohorts. This presentation explores a practical approach to harnessing the power of SSP in the co-creation of an international service-learning (SL) project. The teachers encountered difficulties in adapting original local SL project to overseas because of resources limitations. By inviting students who studied the same subject in the previous year, with outstanding performance into the decision-making processes for the next cohort, this model encourages students to contribute their unique insights and ideas in redesigning the SL project. With the students’ first-hand experience and thorough understanding of the subject’s intended learning outcomes, their contribution can make the subject more impactful and aligned with the needs of students. Not only does this approach benefit the teachers by providing a deeper understanding of student needs, but it also fosters students’ personal growth and leadership development.

Abstract

STEM education is essential in today’s curriculum even for university students. However, traditional classroom-based instruction methods often lack interactivity and tailored experiences that foster student engagement and comprehension. The integration of Virtual Reality (VR) and Artificial Intelligence (AI) generative chatbots has emerged as a transformative influence on the teaching and learning process. Despite this, limited research has explored the impact of advanced technology on STEM learning outcomes. This study explores the potential of employing VR and AI as tools to facilitate teaching to enhance students’ learning outcomes. 120 university students are involved in this study to examine the difference in learning outcomes by utilizing three instructional approaches for learning projectile motion: (1) a traditional didactic classroom, (2) a game-based VR metaverse, and (3) a game-based VR metaverse enriched with a generative chatbot-based pedagogical agent. The study prudently evaluated alterations in student motivation, cognitive benefit, and learning outcomes. Preliminary findings suggest that incorporating VR and AI into teaching considerably enhances student engagement and cognitive participation. This study demonstrates how the integration of VR with AI can elevate student engagement, comprehension, and skill acquisition in STEM education, paving the way for a more captivating and effective learning environment in the Edu-metaverse.

Abstract

KnowLearn is an interactive learning assistant system designed for architecture, engineering, and construction (AEC) education, where personalized recommendations for students in virtual learning environments remain under-explored. An educational knowledge graph (KG) was constructed to contain multifaceted information by connecting pedagogical, learning performance, and learning feedback data as sub-graphs. A heterogeneous graph attention network (HAN) was implemented to infer latent information in the educational KG and identified essential factors shaping students’ acceptance of virtual learning environments. Based on sampling data of 107 students from the Hong Kong Polytechnic University, Department of Building and Real Estate, we found students’ self-efficacy, intention to use, and in-class quiz performance were significant predictors of final learning outcomes in subjects that adopt virtual learning environments. This project further deployed a local-based large language model (LLM) Qwen-7B and built an interactive graphical user interface (GUI) with Gradio. Utilizing the information preserved in the educational KG and learned from HAN as the basis, this LLM facilitated conversations between students and KnowLearn, enhancing personalized recommendations while securing student privacy. The developed system contributed to helping improve the learning experiences and performances of AEC students within virtual learning environments.

Abstract

We aim to investigate factors affecting students’ intention to join blended learning courses in higher education sector using Community of Inquiry framework and Unified Theory of Acceptance and Use of Technology (UTAUT) model. Stimulus-Organism-Response (S-O-R) model was employed to develop a new research framework while constructs in the Community of Inquiry are Stimulus and constructs from UTAUT are considered as Organism and Response. A survey was conducted with undergraduate students in a Hong Kong higher institution. It was found that Teaching Presence (TP), Social Presence (SP) and Cognitive Presence (CP) were associated with performance expectancy, social influence and effort expectancy respectively. Performance expectancy and effort expectancy were associated with social influence. Social influence was associated with students’ attitude towards blended learning. Institution support was not related to the students’ attitude towards blended learning in the post-pandemic period. Attitude towards blended learning was associated with their behavioral intention to participate in blended learning. Online and offline tools could be adopted to improve the students’ acceptance towards the blended learning approach.

Abstract

Higher education programs often focus on disciplinary knowledge and professional skills, with cognitive skills given top priority. As a timely response to limited education for wellbeing and non-cognitive skills development, PolyU’s Leadership and Intra-personal Development Team developed four subjects, including Tomorrow’s Leaders, Promotion of Children and Adolescent Development, Service Leadership, and Service Leadership through Serving Children and Families with Special Needs to nurture students’ leadership, improve their wellbeing, and promote their whole person development. These subjects aim to nurture students to become ethical leaders of tomorrow and responsible citizens by adopting a holistic youth development approach based on cutting-edge theories and research on late adolescence and emerging adulthood, leadership development, and service-learning. To date, over 27,000 students have taken the four subjects. Different evaluation methods involving multiple stakeholders over time have demonstrated positive and significant impact of the four subjects on students’ wellbeing and holistic development. Positive feedback from students and recognition from the higher education community have contributed to these subjects receiving numerous prestigious awards, both internationally and locally. These include the UGC Teaching Award 2018 and the Gold Award in the Nurturing Wellbeing & Purpose category at the Wharton-QS Stars Reimagine Education Awards 2021.

Abstract

With the development of innovative technology, virtual reality (VR) has become very popular and accessible to the public. There has been growing evidence that VR can influence people and change their values and behaviors. VR encourages individuals, especially teenagers, to engage in a specific behavior, such as pro-environmental behavior (PEB). Pro-environmental behavior (PEB) allowed lowering the environmental harms deliberately and substantially enhancing the future harmony. Using Value-Belief-Norm (VBN) theory, the present study aims to examine the relationship between teenagers’ perceived values and pro-environmental behavioral intention in VR platforms. Students (N = 120) were invited to visit the VR lab for an immersive experience focused on carbon footprint. The results showed that hedonic value predicts pro-environmental intention, whereas altruistic value predicts awareness of responsibility of individuals. The findings of the study will contribute to both theoretical and practical contributions. From practical perspectives, integrating VR into sustainability education can enhance student engagement by providing immersive and interactive VR experiences. This innovative approach of teaching fosters students’ pro-environmental intention, raising awareness of personal responsibility in caring for the environment. By incorporating VR elements into programme development, higher education institutions can better equip students with the knowledge in sustainability to address future environmental challenges.
