Adaptive Scaffolding for Learning Fraction among Students with Learning Disabilities
Scaffolding is generally attributed to Wood, Bruner and Ross (1978) who describe it is as a: ∙∙∙process that enables a child or a novice to solve a problem, carry out a task, or achieve a goal which would be beyond his unassisted efforts (p. 90). If a leaner is scaffolded by the tutor, he could not lonely accomplish the task at higher level, but also would be able to internalize their thinking, strategies or mechanisms used to be able to approach other similar tasks (Rogoff and Gardner, 1984). Recognizing its merits and potential benefits, scaffolding has become the frequently discussed topic in the field of learning sciences and relevant research areas. Recently, computer-mediated scaffoldings attract eye balls of many educators and scholars with focusing on their effectiveness of students’ learning. Although relevant studies have been conducting for addressing this, limited studies exploring the students with learning disabilities learning abstract concepts in key subjects in STEM education. To bridge the gap between research on computer-mediated scaffoldings and its impact on students with learning disabilities, in this proposed project, we will conduct research on the influence of computer-mediated scaffoldings on students who have learning disabilities learning the mathematical concept: fraction, which has been identified the concept received comparative more misconceptions and learning difficulties in maths subject. In the study, the research team will design the computer-supported mathematic program following a similar program called Fun Fraction (Shin and Bryant, 2017) with particular design features of fixed scaffoldings and adaptive scaffoldings. Students with learning disabilities will be recruited and randomly assigned into three groups:1) fixed scaffolding 2) self-selected scaffolding; and 3) performance-based scaffolding. Pre- and post-tests will be administrated and the results will be analyzed for exposing the impacts of different types of computer-mediated scaffoldings on students maths learning. The quality of tasks regarding to fraction calculation done in the computer program will also been categorized and analyzed for identifying students differences in the conceptual understanding. Classroom observation will be conducted for observing students’ interaction with the program and the teacher, which will be used a supplementary data for identifying the differences affected by these types of computer-mediated scaffoldings. The study will inform the learning design of maths subject, technology-supported learning, as well as teacher education in special education. Furthermore, the study will fill the blank of the research on learning disabilities students’ learning supported by technology.

Effective Implementation of the Flipped Classroom Approach in Hong Kong Higher Education for Enhanced Learning Outcomes
The notion of ‘flipped classroom’ has attracted much attention in recent years because it has the potential of substantially enhance teaching and learning. Flipping the classroom is regarded to have strong theoretical basis of the learning enhancement. It is, for example, mentioned to be in line with our modern understanding about how people learn and it is capable of incorporating new educational concepts such as personalized learning, peer learning, and learning through construction of knowledge with active engagement in learning activities, etc.
The project provides the essential support to teachers at a number of universities in Hong Kong who would like to adopt the innovative teaching and learning approaches. Through the collective effort of the participating universities, experiences and expertise will be shared to provide effective support that should allow practitioners to overcome the many challenges mentioned above and harvest the best possible from this new pedagogy.

Analytical Solutions for 2-component Shallow Water System
In the proposal, we study the symmetry reduction of some shallow water equations, for example the 2-component Camassa–Holm, Dullin-Gottwald-Holm, Degasperis-Procesi, Fornberg-Whitham and Degasperis-Procesi Equations. The shallow water systems are important to study the ocean dynamics. In details, we would like to study the analytical or exact solutions for the above shallow water equations. We want to apply the new solutions for modeling the drifting phenomena of the ocean fluids, like Tsunamis. There will be a lot of potential applications of the new constructed solutions for real world applications. For the analytical or exact solutions, scientists can use it as reference solutions to check the numerical methods. Therefore, they can design more accurate methods for modeling the real cases.

Undertaking of the International Project on ‘Interests and Recruitment in Science’ in Hong Kong and Guangzhou
This is a pilot study of a large proposal which is based on the international comparative research project called Interests & Recruitment in Science (IRIS), which aims to help improve recruitment, retention, and gender equity patterns within STM education and careers. The IRIS project has been funded (with a total budget of about 1.3 million Euros) by the EU (European Union) under the “Science in Society” category of the Seventh Framework Programme (7FP) for research and technological development. A consortium was formed by the researchers from six universities or institutions in five different EU countries. International associate partners are being recruited to participate in this study, but they need to apply for the relevant research funding from their respective countries or regions. As the 7FP is the EU’s chief instrument for funding all research-related EU initiatives (with a total budget of 51 billion Euros) over the period of 2007 to 2013, those funded projects should be recognized as playing a crucial role in attaining the goals of increasing growth, competitiveness, and employment in the EU member states. In Hong Kong, the findings from this project will enable education officers and teachers to provide well-informed advice and initiate relevant supplementary policy or practice to refine the new senior secondary curricula in STM as recently implemented. By acquiring a similar understanding of those students in the nearby city of Guangzhou, the Hong Kong tertiary education sector will be in a far better position to recruit first-tier students from mainland China and thereby attain its goal of becoming an educational hub in the Asia-Pacific region.

Enhancing the relationship of teaching and learning: What is the knowledege base of teaching and how can it facititate learning?
The relation of teaching and learning rests on how theories can be linked to practice. Very often, teaching theories emerge and vary in quite a number of ways and they do not readily respond to what students need to know. With this in mind, Shulman and his associates at Stanford University have worked on a practical way of approaching subject matter, school curriculum and pedagogy with an emphasis of “pedagogical content knowledge” (see Grossman, Wilson and Shulman, 1989; Wilson, Shulman and Richert, 1987) which has groomed during the last two decades. In substance, Shulman highlighted four sources of knowledge base of teaching: (1) scholarship in content disciplines, (2) the materials and settings of the institutionalized educational process (for example, curricula, textbooks, school organizations and finance, and the structure of the teaching profession), (3) research on teaching, social and cultural phenomena that affect what teachers can do, and (4) the wisdom of practice itself (Shulman, 1987). In this study, Shulman’s framework is adapted and used for developing the knowledge base of teaching in the newly implemented 335 curriculum which requires new teaching and learning. Theory and practice will be linked by academics’ input of the new curriculum in the in-service and pre-service courses and followed by student teachers’ application of their knowledge in their school contexts during teaching practice. Through in-depth investigations, the study aims to develop a useful pool of cases of how teachers will transform their knowledge in real contexts.

Evaluation of effectiveness of e-learning materials in senior secondary science and mathematics subjects
The provision of quality and sufficient resources of interactive self-learning is one of the main foci of the third round of Hong Kong Government’s strategic policy to integrate ICT (Information and Communications Technology) in learning and teaching – “The Third Strategy on IT in Education: Right Technology at the Right Time for the Right Task “. It is in fact built upon the earlier strategies of empowering learners and teachers with IT, enhancing educational leaders to integrate IT in schools and provision of necessary IT infrastructure and training to teachers etc. On the other hand, since September 2009 the New Senior Secondary Curriculum has already been implemented in Hong Kong to re-align the senior secondary and university education system with those found in most parts of the world, especially in Mainland China and USA. Both the Science and Mathematics Key Learning Areas are affected by the NSSC because the curriculum structure and the assessment requirements have been substantially revised. At the same time, an e-learning provider company called Hanlun Information Limited has started to develop a large bank of learning objects (LOs) in the 3 science subjects (to wit, Physics, Chemistry and Biology) and the Mathematics subject at the NSSC level. For our development of the new self-funded Bachelor of Science Education (Honours) (Science & Web Technology) programme at HKIEd, we have met and interviewed the key personnel of that company, knowing that they need our professional service to objectively assess the quality of their LOs and at the same time they could provide a good opportunity for us to conduct research on the learning effectiveness, implementation feasibility/difficulties and students’ and teachers receptivity and attitudes towards the use of e-learning materials to supplement regular school lessons.
This project aims to
1. evaluate the learning effectiveness of the learning objects as developed by an e-learning provider;
2. find out the role of feedback in self regulated learning strategies (SRLS) used and
3. investigate the role of instruction in developing students’ SRLS.

The Interface between the New Senior Secondary Curriculum and the Tertiary Education
The endorsement of the HKSAR to adopt a 3-year senior secondary and 4-year undergraduate academic system to be implemented in 2009-2012 will mark a new page of the Hong Kong education system. Under the new sywstem, a new curriculum, namely, the New Senior Secondary (NSS) curriculum will be adopted. The NSS curriculum is found different from the existing secondary curriculum in terms of curriculum goals, learning contents, teaching and learning strategies and students' learning outcomes. It is anticipated that the adoption of the NSS curriculum will have significant impact on the tertiary education. Respectively, the tertiary institutions will need to design new curriculum to accommodate the needs of the NSS graduates. The study will enable a search for such ground so that relevant and feasible plans can be made for the future changes in HKIED and tertiary education in Hong Kong.
