分圆数a-bx中的平方数

设a、b是给定的非零整数.设p是素数,x是p次本原单位根.证明了当b〉a〉0,b是奇数且p〉max（30,2blog（2eb）） 时,abx不是平方数.     

关于制定我国国家质量教育标准的几点思考——基于美国波多里奇国家质量奖教育标准的比较研究

国家质量教育标准是用以衡量教育组织达到某种程度或水平的质量或数量要求的规定,主要是质量管理方面的要求或优质的规定,具有标志、导向、甄别、激励、促进等功能。制定国家质量教育标准,是一个国家教育质量管理机制健全和完善的主要标志之一,也体现了国家整体的竞争力,目的是为了促进教育组织提高管理效率和绩效。美国在这方面的实践颇具特色,值得借鉴。     

浅谈成人小提琴教学

小提琴课是中学音乐教师培训中的一门比较重要的课程。根据成人学生的特点,让他们在掌握小提琴演奏基本技术要点的同时,更好地掌握教学法,使他们毕业后能胜任中小学音乐课教学及课外活动的辅导,是一项难度较大的教学工作。必须找出成人学生在学习中存在的困难和问题,运用正确的教学方法加以解决。     

Children and adults' intuitions of what people can believe

Two preregistered studies tested how 5- to 6-year-olds, 7- to 8-year-olds, and adults judged the possibility of holding alternative beliefs (N = 240, 110 females, U.S. sample, mixed ethnicities, data collected from September 2020 through October 2021). In Study 1, children and adults thought people could not hold different beliefs when their initial beliefs were supported by evidence (but judged they could without this evidential constraint). In Study 2, children and adults thought people could not hold different beliefs when their initial beliefs were moral beliefs (but judged they could without this moral constraint). Young children viewed moral beliefs as more constrained than adults. These results suggest that young children already have sophisticated intuitions of the possibility of holding various beliefs and how certain beliefs are constrained.

关于指数Diophantine方程a~x+b~y=c~z的一个猜想

设r是大于1的奇数,m是偶数,U_r和V_r是适合的整数,证明了:当r=3(mod4),m=2(mod4),m>r/Ⅱ且c是素数方幂时,方程口。a~x+b~y=c~x仅有正整数解(x,y,z)一(2,2,r).     

Cognitive and environmental predictors of early literacy skills

Not all young children benefit from book exposure in preschool age. It is claimed that the ability to hold information in mind (short-term memory), to ignore distraction (inhibition), and to focus attention and stay focused (sustained attention) may have a moderating effect on children’s reactions to the home literacy environment. In a group of 228 junior kindergarten children with a native Dutch background, with a mean age of 54.29 months (SD = 2.12 months), we explored therefore the relationship between book exposure, cognitive control and early literacy skills. Parents filled in a HLE questionnaire (book sharing frequency and an author recognition checklist as indicator of parental leisure reading habits), and children completed several tests in individual sessions with the researcher (a book-cover recognition test, PPVT, letter knowledge test, the subtests categories and patterns of the SON, and cognitive control measures namely digit span of the KABC, a peg tapping task and sustained attention of the ANT). Main findings were: (1) Children’s storybook knowledge mediated the relationship between home literacy environment and literacy skills. (2) Both vocabulary and letter knowledge were predicted by book exposure. (3) Short-term memory predicted vocabulary over and above book exposure. (4) None of the cognitive control mechanisms moderated the beneficial effects of book exposure.
