很多學(xué)生和家長都有一個誤解，以為參加學(xué)術(shù)活動不用著急，時間有的是，直到高中畢業(yè)都可以 “慢慢比”。要知道學(xué)術(shù)活動一般流程較長，出成績時間也慢，從初賽到出結(jié)果可能會用到半年甚至更久的時間。如果想將成績用...
近年來，隨著全球經(jīng)濟、科學(xué)及技術(shù)迅速發(fā)展，對人才教育的要求也隨之增加，傳統(tǒng)教育已然不太滿足社會轉(zhuǎn)變的需求，在此情形下，STEM教育應(yīng)運而生，是目前教育的潮流趨勢，對于孩子的成長和發(fā)展更是有著明顯的優(yōu)勢...
在標(biāo)化成績逐年上漲的背景下，作為一門頂尖的國際性物理學(xué)術(shù)活動，BPHO的優(yōu)秀學(xué)術(shù)活動成績會讓你在眾多相似競爭力的孩子中脫穎而出，在牛劍藤校的本科申請中獲得額外優(yōu)勢，尤其是想要本科學(xué)習(xí)物理、工程、材料類...
