spiraling in the Ukraine - from Exo

In Soviet schools the content with building-on spiraling was set across a number of years. Lets say, biology would start in grade 5 and it will be Botany (2 times a week), then Zoology (grades 6-7, twice a week), then Human Anatomy and Physiology (grade 8, twice a week), then General Biology (grades 9-10, twice a week). Of course, topics were studied in logical order according to evolution theory, and concepts of cells, tissues, organs, functions were coming up again and again. It was allowing for understanding of complexity and patterns in living things and processes.

Here I have to teach general bio (Living environment) to students who have no idea of plants stuctures, animals, or human's anatomy and functions; I have to mix it all together with emphasis on molecular biology (that requires knowlege of chemistry) and genetics, that heavily connects with evolution. Many of my honor students don't know that insects pollinate the plants!

When I was in school, by the time we had general bio, we knew evolution of plants, organization of animal kingdom, anatomy of humans, and were up to organic chemistry in chemistry class and nuclear physics in physics class that was well alligned with molecular bio and gene engineering. Oh boy... And when in vet school, we took the entrance exam in bio (covering everything in curriculum from Botany to General bio) and didn't have a general bio class ever again.

BTW, from my trip to Ukraine: the school curriculum is still in place the way I had it - still logically built, but spread over 12 years now. However, there is no school that would have students sitting 8 periods per day. The maximum number of periods students can have is 6 in grades 6-12, and 5 in grades 1-5. A period is 45 minutes. The school year starts September 1st, and ends May 25th, with final exams in higher grades scheduled from May 28-to June 12.

How interesting. In NZ we did nuclear physics in both chemistry class and physics class, from different directions of course.
