浅论梅山婚育谚语的教化功能

梅山地区独特的自然人文环境孕育出了梅山婚育谚语,梅山婚育谚语具有很强的教化功能,既有积极的教化功能,也有消极的教化功能,积极方面主要表现在教育人们要树立正确的择偶观、家庭观和生育观,消极方面主要表现在宣扬了男权主义思想和唯心宿命论思想。我们要辩证看待,科学扬弃。     

Taking active learning into the primary school: a matter of new practices?

This paper examines the extension of active learning pedagogical practices familiar in preschool settings to the first class of primary school. Policy and practice guidance in the UK is advocating the benefits of experiential learning as a way of engaging young children as they move into primary school but for teachers this means a move to new practices which can be in tension with other expectations. In this paper, the rationale for active learning is considered along with an account of the classroom activities of teachers and children in five primary schools that were implementing the policy shift to active learning. The children in these classes spent varying amounts of time in whole class activities led by the teacher or in small groups directed to engage with specific activities. They had opportunities to engage and respond verbally, through manipulating objects and with physical actions but the emphasis was on planned, teacher-directed learning activities. The characteristics of active learning as introduced in these innovative classes are compared with the expectations of practice guidance and theorising about early learning.

光照强度对七子花苗期光合蒸腾特性的影响

对光照强度对七子花苗期光合、蒸腾特性的影响进行了研究,得到如下结果:净光合速率最适温度为25～30℃,高光合有效辐射和高温下光抑制加剧。蒸腾速率随着温度的升高而增大,在同一温度下高光合有效辐射使得蒸腾速率下降。29℃下饱和光强为890μmol m~(-2)s~(-1),表观量子效率为0.0325,光补偿点为44μmol m~(-2) s~(-1),随着光合有效辐射的增强,气孔阻力减小,高光合有效辐射下,气孔阻力有所上升,蒸腾速率与气孔阻力高度负相关。在29℃的饱和光强下,羧化效率为0.0351,CO_2补偿点为173μmol mol~(-1),低于或高于饱和光强,羧化效率下降,CO_2补偿点升高。     

Wake Up That Back Row! Interactive Library Instruction Without Hands-On Student Computers

Abstract

A review of education literature reveals a pedagogical shift away from linear, step-by-step, instruction toward a fostering of critical thinking and information literacy through active student participation. This conceptual change reflects advances toward cooperative and participatory learning in education. In addition to the students learning more when they are engaged and thinking, we are invigorated as instructors and our tendency toward burnout is reduced or alleviated. This article discusses how those bibliographic instructors who only have one teaching computer in the instruction room can involve the students in their own learning. The author shares ways to conduct a fifty-minute bibliographic instruction session in which all of the students are intellectually engaged in the research process, actively participate in the problem solving of on-line searching, and have fun in a library. Once the students are given agency in the bibliographic instruction session, they begin to develop the critical thinking skills essential to mastering the tools and methods of library research.     

积极财政政策对区域经济增长与差异的影响

本文利用面板数据模型和时变参数模型分别考察了积极财政政策对我国区域经济增长和差异的影响。分析表明,积极财政政策对我国区域经济增长具有较强的促进作用,其中对西部地区的正向影响力度最大,中部地区次之,东部地区最小。积极财政政策并没有有效地缩小我国区域经济差异,反而促使我国区域差异进一步增大,但影响力度逐年减弱。     

高校BBS活跃用户信息行为分析

高校BBS中的活跃用户发帖量大,而且都积极回复他人的帖子。根据所发主题帖数和获得回帖数的不同,可将活跃用户分为领袖型、实力型、热情型和回应型4类。活跃用户的点入度和点出度呈显著正相关关系,活跃用户的回帖数和获回复数显著正相关,活跃用户所发主题帖数与他们回复的主题帖数也显著正相关。
