全球定位系统实践教学模块的探索与研究

随着全球卫星导航系统的不断完善,全球定位系统课程成为普及卫星导航知识的必要手段。本文针对地理信息系统专业和测绘专业的《全球定位系统》课程教学过程中的一些问题进行了较深入的讨论,并就教学实践提出了自己的几点看法。     

关于函数方程ψ(n~(x+y))=n~xψ(n~y)+n~yψ(n~x)

对于正整数k,设ψ(k)是k的Dedekind函数.本文证明了方程ψ(nx y))=nxψ(ny) nyψ(nx)无正整数解(n,x,y).     

The effects of phonological and morphological training on speech perception scores and grammatical judgments in deaf and hard-of-hearing children

Seventeen primary school deaf and hard-of-hearing children were given two types of training for 9 weeks each. Phonological training involved practice of /s, z, t, d/ in word final position in monomorphemic words. Morphological training involved learning and practicing the rules for forming third-person singular, present tense, past tense, and plurals. The words used in the two training types were different (monomorphemic or polymorphemic) but both involved word final /s, z, t, d/. Grammatical judgments were tested before and after training using short sentences that were read aloud by the child (or by the presenter if the child was unable to read them). Perception was tested with 150 key words in sentences using the trained morphemes and phonemes in word final position. Grammatical judgments for sentences involving the trained morphemes improved significantly after each type of training. Both types of training needed to be completed before a significant improvement was found for speech perception scores. The results suggest that both phonological and morphological training are beneficial in improving speech perception and grammatical performance of deaf and hard-of-hearing children and that both types of training were required to obtain the maximum benefit.     

关于三个连续正整数平方和中的素数方幂

设x,n是正整数，p是素数。证明了：如果x^2 (x 1)^2 (x 2)^2=p^n，则必有n=1。     

关于方程S_x(n)=S_y(3)

对于整数m、n(n≥ 3) ,设Sm(n)是第m个n角数 .本文证明了 :当n >6且n - 2是平方数时 ,方程Sx(n) =Sy( 3)无正整数解 ;当n >6,2 +n且n - 2非平方数时 ,该方程有无穷多组正整数解

关于高职艺术设计专业“设计表达基础课程群”的研究

根据项目课程的观点，把高职艺术设计学科专业课程组成的主体结构分为“职业能力经验的准备阶段、职业能力了解的模拟阶段和职业能力掌握的实习实训阶段”；简析把“设计表达基础课程群”来对应“职业能力经验的准备阶段”的依据；并提出在高职艺术设计专业建设“设计表达基础课程群”应注意的事项。     

对我国成人教育实施非均衡发展战略的思考

由于受区域经济、地理环境、化传统等诸种因素的影响，我国成人教育发展呈现出“东高西低”的阶梯状形态。21世纪初要实现我国成人教育的持续、高效和迅速发展，必须实行非均衡发展战略。     

Rethinking inequalities between deindustrialisation,schools and educational research in Geelong

Inequalities have historically been conceptualised and empirically explored with primary reference to the human. Both measurements of educational inequalities through the production of data about students, teachers and schools, and ethnographic explorations of inequalities in the spoken accounts of human actors in schools can elide affective histories and material geologies of the earth that entwine with societal inequalities, and political questions of the relation between particular human bodies and the earth. In this article, we question: What might it do to rethink the concept of educational inequalities beyond human relations, from within a specific geographical territory? We seek to rethink inequalities including but exceeding these human relations; we argue that inequalities between humans, and between humans and the more-than-human, are materially generated and perpetuated. We offer three theoretical trajectories that consider the affective, spatial and material dimensions of inequality to rethink the relations between inequality, deindustrialisation and schooling. Educational research is implicated in the (re)production of inequalities, as well as having the potential to be part of the production of more equitable relations.
