Modern enlightenment on the theory of george polya ' s mathematical education 波利亚数学教育理论的现代启示
I dont want it , polya ; tell them to take it away , said natasha “用不着了,波利娅,吩咐他们把它拿走吧。 ”
Sv40 polya signal and two loxp sites was added consecutively after the termination codon taa , and then a gfp gene was inserted between the two loxp sites 在三个终止密码子taa之后,连上sv40polya 。 sv40polya之后,又连上两个loxp位点。在两个loxp位点,插入标记基因gfp 。
A late baculoviral transcription initiation motif ataag was found 65 nt upstream of the putative translational start site and a polyadenylation signal aataaa was identified 14 nt downstream of the taa stop codon 在其起始密码子上游- 65nt发现杆状病毒晚期启动子转录起始信号ataag ,在其终止密码子下游- 14nt发现polya加尾信号aataaa 。
Demonstration research 1 interprets that under me normal demand there are no distinct diversity between the grade of the experiment class and the contrast class , but the grade of the experiment class is only a little better than that of the contrast class . but the grade of the experiment class where g . polya inspiring method was used is the best 实证研究一,说明了在常规要求下实验班与对比班数学成绩没有显著性差异,只是实验班比对比班成绩稍好一些,而含波利亚启发法的实验班成绩最好;实验班的学生成绩差距缩小,仅含分层教学的实验班的效果最好。
