Learning the Dynamics and Beauty of Mathematics through GeoGebra

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.

Co-Creating E-learning Tools: Combining Technology with Interpreting

banner


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.


banner

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.

Embracing Teaching and Learning Challenges and Trends in Higher Education

embracing_banner

Educators, wherever we are, should keep up with the challenges and trends in higher education worldwide. One effective way to stay informed is to engage in dialogues with colleagues from around the world. On 20 June, 2017, we learnt about the top 10 challenges and trends in Australian universities in a seminar delivered by Dr Caroline Steel, Strategic Educational Consultant, APAC, Blackboard International ASCILITE Life Member Awardee and Past President Adjunct Academic, The University of Queensland.

The following is the list of key challenges and trends ranked by Australian academic leaders in a study led by Dr Steel:

10 Teaching and Learning Challenges 10 Teaching and Learning Trends
  1. Student career development and employability
  2. Student engagement and satisfaction
  3. Assessment and feedback
  4. Technology-enhanced pedagogical practice
  5. Student attrition
  6. Improving work-integrated learning
  7. First year experience and transition
  8. Personalized adaptive learning
  9. Academic adoption of educational technologies
  10. Academic misconduct
  1. Learning analytics;
    Unbundling qualification
    (both items ranked number one)
  2. Teaching quality standards;
    Fully online courses;
    Students as partners
  3. Mobile-enabled learning;
    Adaptive learning technology
  4. Digital examinations
  5. MOOC’s;
    Open Education Resources (OER’s)

Key Challenges in Teaching and Learning
Student career development and employability is considered to be the biggest challenge in the Australian higher education context. In the past, universities mainly focused on training students into critical thinkers. In today’s rapidly changing society, educators should take one step further to educate both the ‘thinker’ and the ‘worker’. Given the rapid development of automation, AI and cognitive computing, some jobs may no longer exist in 10 years’ time. Students may not be fixed to one career throughout their lives. To prepare students for this highly uncertain future, HE institutions should help them acquire various employability skills and develop cross/trans-disciplinary thinking.

The second challenge is student engagement and satisfaction, in both on-campus & online teaching. According to Professor Karen Nelson, an interviewee in the study, student engagement constitutes of three parameters: behavioural, cognitive and affective. The challenge for universities is to “create the educational conditions that will trigger emotion and motivation so that students are engaged.”

Major Trends in Higher Education
The two most prominent trends in Australian higher education are learning analytics and unbundling qualification.

Learning analytics is a potential game changer in higher education. ‘There is enormous potential in learning analytics,’ said Professor Martin Carroll in an interview for the study. However, even though analytics have been used by lots of industries in Australia, high education is falling behind. It is necessary for institutions to keep up with the trend and look for ways to use analytics to improve teaching and learning.

Unbundling qualifications is another prominent trend in Australian higher education. Universities are now looking into the possibility of unbundling qualifications and micro-credentialing as alternative ways to provide learning, so that learners can obtain the skills they need as quickly as possible. For example, instead of completing an entire MBA programme, some professionals may only want to learn certain components of the degree. If universities are able to repurpose some of the content, then more choices will be available to learners. After obtaining skills and credits from various programmes and fields, learners can demonstrate their expertise in their e-portfolios.

Technology
It is worth noting that, among the top 10 T&L trends, 6 are tech-related, namely

  • Fully online courses
  • Mobile-enabled learning
  • Adaptive learning technology
  • Digital examinations
  • MOOC’s
  • Open Education Resources (OER’s)

This finding is certainly encouraging as the use of technology enhances teaching and learning and better prepares institutions for the challenges in higher education. Technology allows flexibility in learning and makes personalized learning possible. Learning management systems and grading tools such as Turnitin make it easier for teachers to assess students and provide feedback. The blending of face-to-face lectures with e-learning tools, such as Mentimeter and Kahoot!, caters for students’ diversified learning needs, which potentially enhances student engagement.

What about Hong Kong?
We are embracing the same challenges in Hong Kong and are working along similar lines. Here at HKU, we strive to cultivate students’ employability skills (e.g. cognitive flexibility, negotiation) and develop cross-disciplinary thinking through events such as Inter-professional Team-based Learning (IPTBL) and Girls4Tech. To enhance student engagement, we are constantly designing new in-class activities, apps and games. To ensure the best learning experience for our students, our efforts in course development is paralleled by research efforts in learning analytics.

More and more teachers are joining the ride in developing MOOCs (on edX and Coursera) and SPOCs to enrich students’ blended learning experience. To further open up learning opportunities to a wider range of learners, we are also exploring the possibilities of unbundling qualifications and MicroMasters and getting ourselves ready for e-portfolios. More initiatives will be in place to shape the T&L landscape in Hong Kong in response to challenges and trends in higher education.

Improving Learning with Data: Lessons Learnt from a Learning Analytics Conference

ppp

The use of technology in teaching and learning has generated learning data at a massive volume. But how can we maximize the impact of learning analytics (LA)? We explored this question in the 7th International Learning Design & Knowledge (LAK) Conference, themed Understanding, Informing & Improving Learning with Data. It was an exciting experience to find out how educators from around the world develop and deploy their LA tools. Some of our colleagues also presented their research on improving video instructions and their progress on developing learning progress dashboards in the conference.

ppp
Discussions in the Morris J. Wosk Center for Dialogue

The conference featured 3 keynote sessions, 30 technical sessions and 16 pre-conference events. It covered various aspects of LA, from modeling students’ learning behaviour to institutional deployment of LA in practices, gathering ideas from cognitive science, learning design, educational psychology, learning technology, data science and other related fields.

ppp
A highly engaging poster session where participants shared their ideas via 30-second pitch talks

Several major takeaways from the conference:
Students’ learning behavior, triangulated with their physiological data such as pulse, gesture, eye movement and brain wave, etc., reflect the process of learning, said keynote speaker Dr. Sanna Järvelä from the University of Oulu, Finland. Her research focused on using multimodal data to support the inquiry of learning. With guidance of existing learning theories, learning scientists could understand better the process and product of students’ learning, and provide suggestions for improvement accordingly.

To ensure effective analysis of students’ learning processes, an adaptive data-driven learning ecosystem should be established, as pointed out by Dr. Timothy McKay, keynote speaker from the University of Michigan. To establish this adaptive system, learning data needs to be continuously collected and integrated. This informs both students and teachers of students’ learning as an individual and in groups over an extensive period of time, throughout or even beyond their university life. In the University of Michigan, 10 years of learning data from different sources has been collected for establishing a learning system. This system advises teachers and students by providing relevant data to them. The purpose of putting data in people’s hands is to support decision making, motivate actions and guide behaviour change.

ppp

Just as research tools are always guided by research methodology, LA tools need to be student-centered and pedagogy-considered. This requires trust and understanding among teachers, system developers, user interface designers and behavioral scientists, whose expertise could jointly contribute to the sense-making of learning data.

For analytics to work well, the data collected from prior experience must be extensive, accurate and relevant. Some classes tend to be more suitable for deploying LA, such as large introductory courses with relatively mature course contents and classes where teachers have a clear understanding of students’ background and ability. The course should also involve a variety of instrumented learning activities, and the course team should constantly and gradually improve the course structure, content and assessments.

Finally, we must remind ourselves that data by itself is not all powerful until actions are taken in response to the analysis. We should also work to ensure that the collection of educational data and the use of LA tools are lawful and ethical.

Learning through gamification

benny

“Statistics point that 5 million gamers in the US spent more than 40 hours a week playing World of Warcraft in 2010 – which is [almost like] a full time job…” said Dr. Benny Ng at the ‘Benny and the Apps: Gamification and Student Learning’ seminar.

If you were given a choice, would you rather go to class or play games? Games may be the majority’s answer. Would a gamified curriculum motivate your learning?

Dr. Benny Ng gave a glimpse of why and how we can gamify teaching to engage students in ‘Benny and the Apps: Gamification and Student Learning’, a seminar held on April 5, 2017. The role of play and a 5-step gradual process to apply gamification were some highlights of the sharing.

benny

“How would you feel when facing obstacles in reality?” Participants in the seminar mostly gave negative answers. Yet, Dr. Ng believes that challenges can turn into a positive force in games, providing incentives for players to keep trying. After all, play provides a freedom to fail, experiment, fashion one’s identity and put in continuous effort. The role of play facilitates better and enjoyable learning.

wordcloud
Answers by participants were directly reflected on a wordcloud through mentimeter

Participants were also asked what behaviours they hoped their students displayed in class, the most popular answers included ‘attentive, engaged, listen, motivated’. These match with characteristics of a gamer’s behaviour, such as persistency, risk-taking, attention to details, problem solving, urgent optimism, active learning, self-disciplined and resilience. In such a way, gamifying a class can motivate students to display the qualities mentioned by participants in the wordcloud.

A 5-step process to apply gamification was introduced:

  1. Understanding the target players and the context
    • Age group? Existent skill sets? Location? Duration?
  2. Defining Learning Objectives
    • Is the assessment rubric clear enough with actionable tasks?
  3. Structuring the experience
    • How can your content be broken down to stages/milestones?
  4. Identifying resources
    • What kind of gamifying resources may be needed?
  5. Applying game elements
    • What kind of self or social elements may be applicable? For example;
      Self: point, levels, time restriction; Social: leaderboards, interactive cooperation

benny

Changing the terminology of your syllabus can already be a start – what about gaining ‘experience points’ instead of ‘scores/marks’, completing ‘quests’ instead of ‘courseworks’, or ‘mission’ instead of ‘instructions’?

Take the risk to innovate and test new ideas, find the fun element in what you teach. If education becomes a joyful experience, students will ultimately be passionate to pursue life-long learning.

A leap forward in Inter-professional Team-based Learning

banner

Inter-professional team-based learning (IPTBL) is an innovative teaching approach which aims at promoting peer-to-peer learning and collaborations across disciplines. In 2016, the Li Ka Shing Faculty of Medicine piloted IPTBL with nearly 600 medical, health and social care students from HKU and the Hong Kong Polytechnic University. This year, the organizing team scaled it up to serve more than 1,000 students from the following programmes: Chinese medicine, medicine, nursing, pharmacy, and social work from HKU; and medical laboratory science, nursing, occupational therapy, physiotherapy, radiography, and social work from PolyU.

The details of implementation are as follows:

Topic of Instructional Unit Date No. of participants
Anticoagulation Therapy January 21, 2017 247
Depression February 11, 2017 310
Fracture February 18, 2017 437
Multiple drugs February 25, 2017 347
Developmental delay March 18, 2017 192
Cancer March 25, 2017 501

What’s new this year?

(1) Venue: To facilitate group discussion and communication between teachers and students, IPTBL was conducted this year in Lecture Hall II at the Centennial Campus, a flat area with mobile chairs and strong WiFi connectivity.

banner
Before: IPTBL was conducted in a lecture theatre setting in the 2016 pilot round. Students in groups tended to face the stage most of the time.

banner
After: Groups were arranged in circles this year. This picture features 71 small groups of five to seven students seated in the spacious Lecture Hall II. The IPTBL team would like to thank colleagues from the Examinations Office, Estates Office and Learning Environment Services of ITS who made all the six sessions possible.

(2) Team progress chart: How to pace the 4-hour face-to-face IPTBL session is a big challenge. While the moderators and content experts had to be very conscious of the time, students also played an important role in moving the session forward. The newly added team progress chart displayed on one of the four screens in front of the hall, indicating whether a particular group had finished the assigned task – just like what a leaderboard does in online games. This provided motivation to students to complete their work in a timely manner, and also gave teachers some idea on which groups to interview in the interactive feedback session.

(3) Peer evaluation: Team-based learning creates many opportunities for students to learn with, from and about each other through intensive interaction and collaboration. During each session, they got to know each other’s expertise and communication style. Peer evaluation is a mechanism for them to provide honest feedback to their peer teammates in terms of four competencies: values/ ethics, roles/ responsibilities, communication, and teamwork. At the end of each session of this year’s IPTBL, students would fill in their peer evaluation scores in an online form. They would then be directed to another page which showed them, in real-time, the average scores that he/she received from other teammates.

iptbl
Dr. LK Chan explained to students how to fill out the online peer evaluation form. By the way, did you notice the balloons in the picture? They indicate the group numbers so that teachers/ facilitators could quickly locate where the teams are.

Exemplary facilitation skills
Team-based learning incorporates many elements of constructivist learning (Hrynchak & Batty, 2012). The teachers (content experts) spent much time to come up with carefully-crafted application exercises which can reveal common misconceptions and debatable topics from which students build new understandings. During the interactive feedback session, many teachers showed excellent skills in facilitating the discussion of a large group of students, such as:

  • not picking the team leader to present the team’s views;
  • asking open-ended questions with a focus on understanding the students’ rationale in picking a particular answer;
  • encouraging students to articulate their thoughts;
  • addressing uncertainties or disagreements;
  • providing a closure after each discussion; and
  • paying attention to teams or students who are not taking part (e.g., by inviting a range of teams to give their opinions).

banner
IPTBL is the Bronze Winner for Discipline Award (Life Sciences) in the prestigious QS Stars-Wharton Reimagine Education Awards 2016. The team celebrated the success after a briefing session in January 2017.

Way forward
The IPTBL team is now reviewing the feedback from students and teachers. They are thinking about improving the implementation in the following ways:

  • shortening the readiness tests in order to leave more time for discussion on the clinical scenario;
  • re-voicing students’ opinions when they contribute something that appears to be complex or not too well understood to students from other disciplines.
  • Adding new functions to the online platform for running IPTBL to provide more informative feedback to both the facilitators and students.

For those of you would like to learn more about IPTBL or contribute to it, please contact Dr. Fraide A. Ganotice, Jr., Program Coordinator at Li Ka Shing Faculty of Medicine, via ganotc75@hku.hk. If you want to get to know the technical aspects of running large classes, you may reach out to the Technology-Enriched Learning Initiative (TELI) via enquiry@teli.hku.hk.

Look forward to IPTBL 2018!

The Role of Higher Education: Lessons from Minerva

banner

There are two things higher education institutions must do when guiding their students in learning. First, we should teach students how to transfer their critical thinking skills from one context to another. Second, we must engage students in active learning and deep processing to develop their capabilities.

Minerva is a non-conventional college startup where students live in seven world cities and interact with teachers and peers via live videos on an online platform in their four-year education. With its growing popularity and low admission rate, it is described by some as a college “tougher to get into than Harvard”. On 17 February 2017, Mr. Ben Nelson, Founder and CEO of the Minerva project shared his secrets of success in Minerva in a seminar titled “How to save higher education in twenty seven easy steps?” at the Hong Kong University of Science and Technology (HKUST).

What should we teach?
Minerva believes that higher education institutions should teach students how to transfer their critical thinking skills from one context to another. Their teaching philosophy focuses on providing students with a framework of thinking applicable in different situations. Education is not meant to provide rote solutions, but ideas and patterns, so that when students encounter a novel situation, they can come up with a novel solution.

The fundamental problem in higher education is that we spent years learning things in an unstructured environment before we learn how to transfer. The goal of Minerva is to alter students’ way of thinking and interpreting the world. “It’s like doing brain surgery,” said Mr. Nelson. He agrees that studying in Minerva can be challenging, but by the 3rd or 4th year, students will have learnt how to parachute into any location and make the most out of any situation.

How should we teach?
We must engage students in active learning and deep processing instead of simply lecturing them because deep processing leads to better retention of knowledge. Mr. Nelson perceives passive lectures as an ineffective way to disseminate information as it does not encourage deep processing – students’ knowledge retention rate drops to 10% by the end of the 6th month, meaning a 90% failure rate.

Based on his examination of empirical evidence, he came to the conclusion that “when you go through deep processing, you get memory for free.” If you only push students to memorize something without going through deep processing, the retention rate will most likely be very low.

Higher education is “the gatekeeper between citizenry and leadership.” It is necessary for universities to keep up with changes, or else we may be in the peril of not existing.

A big thank you to HKUST for inviting us to join this thought-provoking seminar.
