▫ Good evening! Participation in school and city scientific conferences, distance learning, children creating presentations, working with a digital microscope... these are the extracurricular activities of my students.
▫ - Do you feel it? Spring is all around, A green thrill of expectation And incomprehensible desires She poured into the air. - Listen, this is all a hoax, funny inventions of poets. What does this ultimately mean to us? It makes no difference between spring and summer - You understand, in the spring I breathe as if differently I wander around the house in excitement, And I wonder what’s wrong with me! - Probably vitamin deficiency. Eat fruit, wake up later, or maybe it’s from mimosas, be careful with allergies. - I really enjoy spring and feel its whirling, the warmth of the rays, the movement of the planets, both during the day and at night in my dreams. - Don’t bother yourself, think better about your salary, or drink beer out of boredom. And that’s enough talking about it. We don’t understand the alien world - Everyone has their own mentality. But the air is filled with spring And this is the main reality! Petr Davydov 6056349-a1238795 Good evening, Ninochka! This is the first Moscow primrose, and we still have snowdrifts and sub-zero temperatures! Thank you for visiting my page, my faithful friend! Sorry that I can’t properly respond to your wonderful comments, I’m mercilessly thrown out of the portal
▫ Politics, of course! For example, state policy in the field of education. There is so much there - you will hear it and your head will shake. From new and from introductions. From flying, so to speak, someone’s thoughts and making someone’s dreams come true. Through the prism, again so to speak, objective reality. Why not a topic for a pedagogical portal? For example: the liquidation of educational institutions in Karelia. There is no need to complain here - here the “deeds” should be made public! Online publicity sometimes confuses some drivers so much, it confuses them so much that they even begin to hide from reports. So it works! Online publicity is in effect! Or take, for example, religion. Why not discuss the themes of her and her adherents’ coexistence in the world around us? There is no reason not to discuss it. And reasons not to make public (if anyone doesn’t remember, then in Russia there is freedom of speech. A constitutionally enshrined right, yes)) - reasons not to make public the essence and essence of what whose “fundamentals” are studied in schools and beyond. And even more: some really want it to be studied for a long time... Throughout their school life! - Why? - That’s why! - But... How can this be?! - And like this! Why not discuss the correspondence of the stated goals - and the actual implementation of these “statements,” eh? This is interesting! This is right on the edge of the basic law of the Russian Federation! This, I would say, is the civic duty of all of us - to evaluate our existence through the prism of laws... right? What about complaints about life? This is completely natural: people want to live normally, but for them, take it out in the style of “Well, we wanted the best... But for someone it turned out, as always....” Any reason to complain? Why not?! So they share the painful issues among the citizens of our society. So it’s absolutely wonderful that there is where, there is something and there is someone to say.
