For 3 days, I made a daily pilgrimage to NIE, NTU for the Molecular Genetics workshop.
It covered all concepts, procedures and applications of basic recombinant biotechnology. Something like a crash-course revision on year 1 or 2 uni work. Strangely, after 3 years of hiatus, it felt great to be back in the lab again, hearing words like "HindIII, BamI, southern blotting, TBA, TBE.." To revisit the principles from which spawns millions of possibilities.
But that was not new. What struck me was how clear the A/P brought forth these concepts. How simple, elegant, logical, each step or idea was made out to be. Clearly, the A/P is a man of great experience, in research and in teaching. 3 others present who graduated from the same cohort concurred.
While most, if not all of us, have prior knowledge, the A/P was unassuming and took pains to highlight each film obtained from gel electrophoresis, explaining what each band (or absence of) reflects. Two bands because DNA digested, last lane with multiple bands affirm successful random ligation, cannot compare lane from band of undigested plasmid to ladder because former is ccc while the latter is linear, 2 bands because the plasmid could take different forms, shadow because of leaking of well. Band matches so this child's father must be Man 2 not Man 1...
My fellow cohorts recalled how we would be herded into the lab in the afternoons back in uni, follow cook-book protocol and then told by the TAs to submit a report upon receiving our films. On hindsight, we laughed about how we were thrown into the deep end by the TAs and often had to grope through these unfamiliar concepts and interpretations without much response. Not making sense of our bands from gel electrophoresis was a true source of grief!
And this has made us appreciate the A/P of this workshop all the more. I am awed at how he has simplified the concept and method of serial dilution. I am inspired by his incisive assessment of students' concept of homologous chromosomes, how he anticipated misconceptions. Comparison and progression from Southern, Northern Blotting, DNA fingerprinting, DNA profiling, gel elec. His practical advice borne through experience, like agar gel for gel electrophoresis can be reused by microwaving because the DNA denatures after a day, bubbles on gel can be getting rid of by quick flamming. What a good staining of gram negative bacteria should look like.
One may attribute this to class size. Back in the uni, a lab session held about 50 to 70 fresh-faced undergrads in a session. This workshop involved only 8 participants.
But I think that the crux is that, he has a very firm grounding and clear understanding of the subject matter. Together with accumulation of experience, he was able to impart the "fundamental principles", elaborate on what is integral and exemplify by making linkages to applications. The quality of pedagogy can make up for compromise on class size which, in reality, is sometimes a necessary evil.
So i walk away, firmly believing that my mission as a biology teacher is to impart "fundamental principles" (as he calls it) and with this, with today's tools and toys, one may then soar with it. It is also stark to me that for a branch like Genetics, where all creations or products are precipitated from a very "fundamental principal", I have to, all the more, ensure that my students have a very sound foundation. To this end, I would aspire to be like the A/P.
Later in the workshop, and upon some google, I learnt that he was a retired prof from Uni of Malaya, and is currently serving as the Head of DNA centre in NIE, together with his wife, who was training a group of 8 students for International Biology Olympiad today. Both did their PhD in London and he subsequently was conferred DIC too. In uni of Malaya, he used DNA fingerprinting to identify burn victims of plan crash and establish paternity in rape or parenting cases. For one who has seen it all, done it all, he taught us so sincerely and patiently. I feel deeply privileged to be on the receiving end of such fine teaching.
