Professor Sun Kwok, a world-renowned astronomer, devotes his waking hours to exploring the wonders of the Universe. Why did he choose this path, and how did it work out for him? On 27th September, we visited Professor Kwok at the Laboratory for Space Research in Cyberport. In an interview with him, we got to know Professor Kwok as a scientist, an insightful educator, and an astronomy enthusiast brimming with passion.

When did it all begin?
It was not Professor Kwok’s childhood dream to become an astronomer. Instead, when he was studying engineering at university in Canada, one day, as he read Frontiers of Astronomy by Fred Hoyle, he found out that astronomy has much to do with physics, chemistry and biology. He realized that science are tools enabling him to understand the patterns and motions of stars, and the fascinating unknown of their composition, structure and evolution. The idea of investigating the Universe with physics was exciting, and he was inspired to pursue astronomy, eventually making important discoveries and leaving a legacy.

Curiosity and hard work paid off
For Professor Kwok, the Universe is still full of mysteries awaiting him to unveil. Despite hurdles, his curiosity and desire to solve mysteries drive him forward and help him overcome difficulties. Professor Kwok also adds it is all down to diligent preparation and effort, as one would never know when that eureka moment happens. His formula to reaching his goals is constant work, determination and hard work; not so much about natural talent or luck.

His efforts paid off. After countless ventures into deep space through telescopes, Professor Kwok is now the proud discoverer of many nebulae and stars. When asked how does he name his discoveries, Professor Kwok said, “it’s usually because of what they look like. In the case of cotton candy (nebula), it’s because of its shape!”

Places for stargazing
Professor Kwok has made a lot of professional observations on Hawaii’s Mauna Kea. The telescopes on its summit stand 4200 metres above sea level, where the skies are clear and the clouds are well below the observer. It is the location that Professor Kwok considers his favourite to observe celestial wonders.

But is Hawaii the only good place to go stargazing? Many often complain that it is difficult to see stars in Hong Kong due to severe light pollution. Professor Kwok remarks that even in Hong Kong it is not impossible to see, but people just turn a blind eye to them. In fact, Professor Kwok adds, it is extremely easy to see a planet even in Hong Kong, and people are always bewildered when he points to Venus at twilight. Professor Kwok suggests us all to go to the countryside, far away from the city lights, and marvel at the gifts of nature to rekindle our interest for our environment, because “it is all what our ancestors did. Everyone should see the Milky Way once in their lifetime.”

The next adventure
An inquisitive mind enabled ancient people to develop science and make technological advancements. Where is Professor Kwok’s curiosity leading him next? Currently, Professor Kwok works on astrobiology and is studying organic matter in space. He also believes that the integration of different fields of knowledge, such as chemistry, biology and geology, will create a multi-disciplinary perspective and be the future of astronomy.

Professor Kwok always encourages young people to pursue their dreams. “Because at the end, it is your life, and you have to have a career that is fulfilling”.

A new tool in teaching: the Learning Glass October 19, 2017 Posted in: flipped classroom, learning glass, TEFS

ppp

We are surrounded by promises about a technology-enriched learning environment – for example, how online education will supplement face-to-face lectures, how artificial intelligence will provide round-the-clock assistance to students who always work until the small hours. These promises are motivating some of our teachers to bring more innovations to their classrooms. Dr. Rachel Lui, who gave a sharing session last week, is one of them.

Thanks to the Teaching Exchange Fellowship Scheme (TEFS), Rachel was able to visit the University of California, Los Angeles (UCLA) in the summer of 2017 to investigate a new “medium of instruction” – the “Learning Glass”. The tool is a video recording system with a transparent glass board in front of the camera. This allows teachers to maintain natural eye contact with the viewers while presenting the content. The purpose is to engage students in a constructivist process of learning. Rachel’s sharing covered the following topics:

  • what “Learning Glass” is, and how to set it up;
  • why natural eye contact is important;
  • showing the thinking process in science education;
  • how “Learning Glass” is different from PowerPoint; and
  • whether we should invest in tools like the “Learning Glass”.

As a result of her trip, Rachel produced 47 videos for SCNC1111 which are in use from this semester. Here are two samples (click on the image to access the original video):

The informal conversations after the sharing were equally fruitful. “It was really encouraging to see that many teachers care about their courses, and are actively updating their pedagogies,” Rachel said in delight. “Some of them would like to know more about the software that I used, and some were hoping to get to know more about what can be done in the face-to-face classes after lectures are moved online.”

Rachel’s work is one example of what is possible in video lectures. As a next step, she will investigate further how to transform the entire course experience.

TEFS aims to enhance the scholarship of teaching and learning at the university through sharing of excellent pedagogical practices between HKU and other prestigious higher education institutions. Full details of TEFS can be found at http://intraweb.hku.hk/reserved_2/cdqa/doc/TEFS/TEFS_2017-18.pdf.

Professor Sun Kwok is a reowned astronomer who has made many important astronomical discoveries, particularly on nebulae, and is the former Dean of the Faculty of Science and Chair Professor of Physics.

Our Place in the Universe Book Launch Party

What is this book about?
Professor Kwok explains that this book is not about technical knowledge on astronomy and physics. Rather, by following the footprints of 5000 years of astronomical development, it shows the evolution of humans’ way of thinking – demonstrating how humans developed rational thinking through their observations and understanding of the universe. Our Place in the Universe takes us on a journey, studying how the development and advancement in science continuously change humans’ perception of self and the world.

Learning the Dynamics and Beauty of Mathematics through GeoGebra September 11, 2017 Posted in: e-learning, education, geogebra, Mathematics, Open edX

math_banner_SSS

Guest blogger series: Dr. Yat Ming CHAN
Dr. Yat Ming CHAN is a Lecturer at the Department of Mathematics, The University of Hong Kong. Chan specializes in differential geometry and is the developer of HKU GeoGebra resources. Check out this blog post to learn more about his teaching of mathematics.

The Department of Mathematics has been offering a range of courses to provide mathematics education to HKU students across faculties. We have designed courses specifically for students majoring in statistics, risk management, quantitative finance, actuarial science, engineering, business and economics. Almost all these courses involve the training of calculus at various levels. By means of introducing new dynamic and interactive instructional materials, it will be possible to improve students’ motivation and provide them with extra incentives in learning the underlying abstract mathematical concepts. With the support of HKU Teaching Development Grant, we have introduced GeoGebra resources on HKU Open edX for introductory-level mathematics courses.

This platform provides a library of GeoGebra applets to support teaching and learning for introductory-level mathematics courses. GeoGebra is a free and open-source dynamic mathematics software that can construct elements with points, vectors, polynomials and functions. The use of GeoGebra allows visualizations of mathematical ideas and creation of interactive instructional materials. The applets made in the platform will be designed to (i) supplement the concepts developed in class and (ii) prompt students to explore mathematics according to the guidelines.

For each learning object, students can learn or review one to two concepts and will be given opportunities to perform investigatory tasks. Students can click on checkboxes and follow the guidelines to achieve a specific goal, drag the points and move the sliders to observe the change, and input their own functions to examine different cases. All these activities, as well as follow-up questions, can foster student-centered learning and mathematical explorations.

Due to the versatility of GeoGebra, we expect that the materials in this platform will improve teachers’ capabilities to convey abstract and difficult mathematical concepts to students. Teachers and tutors can take advantage of this new resource to create complementary materials for their lectures and tutorials. We also expect that the use of GeoGebra applets in class will improve teacher-student interactions.

We build. We innovate. We share. It is our team’s mission to support teachers in building useful learning resources and sharing knowledge with technology. One recent project is the enhancement of the Resources for Interpreting website (傳譯資源網), and the development of a mobile app “Newssary” instigated by Dr Eva Ng from the Translation Programme of the School of Chinese, Faculty of Arts. Dr Ng is also the recipient of Teaching Innovative Award for the University’s Teaching Excellence Awards in 2017.

The Interpreting Website
Funded by the Knowledge Exchange (KE) Office of HKU, this website provides free learning and training resources for anyone interested in interpreting. One star feature of the website is a glossary of bilingual Chinese-English terms on current affairs. It is a constantly udpated database of thousands of entries collected by students from the news over many years. This database is not only useful for professional interpreters, but also anyone interested in learning buzzwords in the news.

banner

Website Enhancement
For all glossaries and databases, a user-friendly searching function is indispensable. The database now supports searching by Traditional Chinese and Simplified Chinese. An intelligent search function has also been added recently. For example, if you input “appr h” in the search bar, it will prompt you with “Appreciate Hong Kong”. In other words, even if the input information does not correspond exactly with the entries in the database, you will still be prompted with possible matching items and related terms.

Our team further enriched the website by producing a video on what is interpreting. We also set up a server and advised Dr Ng’s team on website architecture and theme development.

Achievement
The website received an overwhelmingly positive response from its users, ranging from academics, PhD candidates and members of the general public:

  • “[The website] has everything that an interpreter, or anyone who teaches interpreting, or anyone who wants to use it for client education would want.” – Professor Holly Mikkelson, Middlebury Institute of International Studies at Monterey, USA
  • “It’s a wonderful contribution for today’s students and practitioners of interpreting and translation.” – Professor Claudia Angelelli, Heriot-Watt University, UK

In recognition for her contribution to the interpreting community, Dr Ng was awarded the Faculty Knowledge Exchange (KE) Awards in 2016.

The Mobile App
Furthering our effort in revolutionizing the website, we have successfully transformed the glossary into an app, “Newssary”, to increase the accessibility of this useful learning resource. One key feature of the app is game-based learning – it is not just a dictionary, but made interactive for users to learn new vocabulary items through games.
