in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

short-response prompt  

read the following excerpt from “fish cheeks” by amy tannin which tan recounts a christmas eve dinner.  

i fell in love with the minister’s son the winter i turned fourteen. he was not chinese, but as white as mary in the manger. for christmas i prayed for this blond-haired boy, robert, and a slim new american nose.  

on christmas eve i saw that my mother had outdone herself in creating a strange menu. she was pulling black veins out of the backs of fleshy prawns. the kitchen was littered with appalling mounds of raw food: a slimy rock cod with bulging fish eyes that pleaded not to be thrown into a pan of hot oil. tofu, which looked like stacked wedges of rubbery white sponges. a howl soaking dried fungus back to life. a plate of squid, their backs crisscrossed with knife markings so they resembled bicycle tires.  

after everyone had gone, my mother said to me. “you want to be the same as american girls on the outside.” she handed me an early gift. it was a miniskirt in beige tweed. “but in side you must always be chinese. you must be proud you are different. your only shame is to have shame.”
