Please check my Сoursera essay 1 The most common and startle problem of Russian pupils is Unified State Exam (https://en.wikipedia.org/wiki/Unified_State_Exam). Pressing is so strong that they leave a school after nine grade. If they do not do that they should study very hard hundreds of hours, make thousands tests, and pay large amount of money for tutors. However, these tests and real knowledge usually not the same. Preparation for that exam have more common with dogs training than education. Maybe exist another way? Yes, few the biggest Russian universities conducts Olympiads for school pupils. The results of which applicants can go to university. Preparation for that event is creative and not ordinary process but it requires very good memory and knowledge. Memory also needs after admission to university also in adult life. As well other people around the world needs memory for their everyday tasks. Importance and quantity of information raise tremendously (https://en.wikipedia.org/wiki/Information_explosion). We call us Information Society (https://en.wikipedia.org/wiki/Information_society) and live in Information Age (https://en.wikipedia.org/wiki/Information_Age). While people do not produce brain implant for memory we should estimate how it works and can be enhance. Because of it I think research of long-term memory it is the most important and interesting thing in psychology. Long-term memory divide into declarative memory (explicit) and procedural memory (implicit, body skills). Declarative memory also divide into episodic (moments of our life) and semantic memory . If we talk about general world knowledge (facts, ideas, meaning and concepts) then it is semantic memory. Namely, study of this mainly reflects on modern education. Psychologists and neuroscientists already done many discoveries about preservation of knowledge. Today we know about importance of rehearsal: we no more reread material, we consciously recall it. Application Anki is the best friend of modern student is result of discovery of Spaced Effect and invention Spaced Repetition System . In addition, scientists estimated benefits of testing effect and nowadays tests more often use for education as instrument that helps consolidate knowledge not only check it. It all of the result of many psychology research that effects on our model of memory, education and ourselves.
