My teaching evolution (2012-15)

Posted by on Oct 4, 2015 in chemistry, Personal, United World Colleges | 0 comments

My teaching evolved every year in the past three years, hopefully for the better.  Here I want to share some of my experiences, which may be interesting for both other teachers and also my students, current and past. 2012-13 In 2012-13 I spent much energy in discovering what works for good teaching.  The first part of the survey was fruitless and confounding.  Many things work to improve learning, indeed, everything works to improve learning.  Giving detailed notes help to improve learning (because students benefit from access to material)...

Our New Assessment Calendar

Background Historically at LPCUWC we centralize student assessments on a paper calendar in the Staff Room.  Not all assessments were consistently updated, testing conflicts were seen but unresolved, and its utility has been limited.  In May 2015 our Director of Studies asked me to look at the a spreadsheet that would be the assessment calendar for the new year.  Over a weekend I shaped the Sheet, making it easy to work with and easy to maintain, and layered with functionalities that help both teachers and students.  This is the corresponding...

Esther’s Speech

Posted by on May 6, 2014 in Personal, United World Colleges | 0 comments

Esther, our well-loved economics teacher, is as “UWC” as one could get.  Growing up in Hong Kong, Esther attended Atlantic College in its early years, and have been teaching at LPCUWC since 1993.  Esther also organizes the UWC Graduate Organization in Hong Kong, and is also a UWC-parent: her daughter Sum has just graduated last year.  The class of 2014 invited her to speak at their graduation, and her talk has so much life and meaning, not only for the graduating class but also for a wider audience.  Esther has graciously given me...

Paper 2 Analytics: first explorations

Paper 2 Analytics: first explorations

I’m a connoisseur for chemistry exams.  (I need a life!)  Writing good exam is an art, where the final paper need to represent an optimal blend of objectives (skills required), topic distribution, chemical theme, and algorithmic complexity, all within a constraint of points.  It’s quite sad that this intricacy is invisible to most. IB chemistry paper 2 is distinctive in that while the format is preserved over the past 20 years — 135 minutes, 90 marks; 40 marks compulsory, 25×2 marks optional — there is a subtle...

The temptations of tutoring

Posted by on Mar 30, 2014 in Personal | 0 comments

Tutoring is big business in Hong Kong.  Various models exists.  On one end are private tutors working 1-on-1.  On the other end are “celebrity tutors” who runs classes of hundreds (via video conferencing to multiple lecture halls), whose airbrushed visage grace billboards and buses.  The common ground between them is that they cost an arm-and-leg, and constitute a shadow education sector apart from daytime education in schools, in which an astounding 86% of senior secondary students enrol in. Since coming back to Hong Kong I have...

Jmol chemical element swatches

Jmol chemical element swatches

Here is an RGB swatch palette for chemical elements, using the Jmol/JSmol convention as defined on its wiki page.  This is an ASE (Adobe Swatch Exchange) file and should be of use across the entire Creative Cloud suite (including Photoshop, Illustrator, and InDesign).  Download here  ; details, installations, and caveats follow. Jmol/JSmol is meant for screen, so the colors were given as RGB values.  Quite a large number of the colors falls outside the CMYK gamut, and there will be a subtle — but noticeable — shift when...
