梵净山国家自然保护区两栖动物分类修订     

张雷 《铜仁学院学报》2008,10(5):123-126

随着两栖动物新种、新属和国内新纪录等陆续发表,导致梵净山两栖动物分类地位陈旧,有许多与当前分类标准不符,给梵净山两栖动物以后的研究带来不便．本文对其分类地位修改进行专门总结,发现与以前相比,梵净山两栖动物科、种数量未变,但一些目、属、种名和原隶于蛙属的种及原隶于锄足蟾科的属分类有改动,同时增加了4亚目、5亚科和5属的分类阶元。这样梵净山拥有两栖动物就由原2目（1亚目）8科11属34种变为2目（5亚目）8科（5亚科）16属34种．  相似文献

Data‐driven refinements of a genetics learning progression     

Moraima Castro‐Faix  Ravit Golan Duncan  Jinnie Choi 《科学教学研究杂志》2021,58(1):3-39

Learning progressions are theoretical models that describe learning of scientific ideas and practices over time. These hypothetical progressions need to be tested and refined in order to productively inform instruction and assessment. In this paper, we report our attempts to revise a learning progression in genetics. In particular, we focused on two constructs that embody core ideas in classical genetics and one molecular construct. The revisions are based on analysis of pre‐ and postinterview data obtained from sixty 11th grade students before and after they engaged in a 10‐week unit that addressed these concepts. We found that while many of the students held ideas that aligned with the progression, there were several distinct dimensions of student reasoning that were not captured and led to substantial revisions of the constructs including: (a) the splitting of the construct dealing with meiosis (E) into two subconstructs (E1‐physical passage of genetic information and E2 – the role of sex cells), (b) the addition of new levels to constructs dealing with the universal nature and organization of the genetic code (A) and construct (F). For Construct A, the lower levels were expanded to include ideas about the localization of DNA in cells and to include ideas about the composition of DNA that were not captured in the progression. Revisions to Construct F included the expansion of existing levels and the addition of modes of inheritance such as codominance and incomplete dominance. The research we present offers insights about a methodological approach that can be used to test and refine progressions, as well as insights about student learning in genetics as we further describe and expand the stepping‐stone ideas in the progression and discuss further the multidimensional nature of learning progressions.  相似文献   

体操动作的讲解与示范   总被引：1，自引：0，他引：1  

张超 《鸡西大学学报》2005,5(6):29-29,31

体操这一学科区别于其它学科的特点是：在一般情况下学生处于动态的环境中，以身体练习为主，其中讲解、示范既是教师和学生沟通的桥梁，又是体操教师最基本的教学手段。标准的示范动作可以增强学生学习体操的兴趣并促使学生快速掌握技术要领。讲解与示范的有机结合，有利于学生技术动作的掌握和教学质量的提高。  相似文献   

经济人假设的修正与经济学的发展   总被引：1，自引：0，他引：1  

周怀峰 《韩山师范学院学报》2006,27(4):7-11

文章从方法论的角度探讨了现代经济学演变所遵循的规律,认为建立在经济人假设基础上的主流经济学随着经济人假设的修正而演变,经济人假设的修正夯实、扩充或改变主流经济学赖以成立的基础,从而扩大主流经济学的研究范围或产生新的经济学分支学科。据此,文章最后预测今后经济学发展的方向,为经济理论的创新提供方法论的指导。  相似文献   

Reworking the science curriculum: A case study in the interdependence between introductory biology and multiculturalism     

Persell  Roger 《Journal of Science Education and Technology》1994,3(4):249-258

Multiculturalism has emerged as the major influence in revising science curricula and teaching, yet misunderstanding about the history and theoretical underpinnings of multiculturalism has made the separation of political and education reform contentious and difficult. Within the context of a new college-wide pluralism and diversity requirement, a large introductory biology course at Hunter College of the City University of New York is now the testing ground for an interdependent model of multicultural education. The implications for multiculturalism, science pedagogy, and the pivotal role of introductory courses are discussed.  相似文献

动词重现紧缩句“V1也V1P”的不对称现象分析     

王霞 《怀化师专学报》2008,(7):80-82

动词重现紧缩句是汉语中具有独特价值的句法结构。在考察“V1也V1P”的肯定形式和否定形式的不对称现象、结构中后现动词带宾语与带状语、补语的不对称现象的基础上。从认知角度解释不对称性;分析与结构相关的标记模式及“V1也V1P”结构不对称的显著性。为进一步研究动词重现紧缩句奠定了基础。  相似文献
