Memory work is essential not only in the humanities subjects, but also in math and science, such as Physics. There are many Physics formulae that have to be memorized as a formula sheet is not provided in exams. There are also specific problem solving strategies that have to be remembered. Even though rote learning is increasingly being de-emphasized, all academic subjects still require a certain amount of memorization. A student who is good at recalling will find it easier to adapt his knowledge and use it creatively.
Textbooks for our school children have become much better over the years. Nowadays, authors are adept at using pretty illustrations, mind maps, and clear language to convey Physics concepts. Many of our brighter students are even able to use MOE-approved textbooks for self-study before the teacher covers the material in class.
In Singapore, it is a common sight to see Singaporean stressed out across all age groups. For students, the stress that they face is managing a packed schedule filled with school work, CCA, additional enrichment classes that are non-academic in nature such as piano lessons and last but not least tuition classes for various subjects.
