发育生物学模式生物

20世纪90年代以来,发育生物学的研究取得了突飞猛进的发展,发育生物学已成为当今最活跃的生命科学研究领域之一。在发育生物学形成和发展过程中,许多划时代的研究成果往往与一些模式生物相关。利用模式生物开展发育机制的研究,具有便捷、高效、深入、系统和有利于成果的延展与应用等优势,常用模式生物的基本特征应成为现代生命科学必不可少的学习内容。     

An integrated approach to biology

Zoology, being a basic bioscience, is essential for a better understanding of applied biological disciplines. A sound background in zoology can often be the key to success in modern day cutting-edge biological research. Students of zoology have many more interesting questions to ask now than ever before. Precisely when did humans take to clothing? How is losing body hair actually correlated to body louse speciation? What is so unique about a schistosome that enables it to parasitize two very different host species, to have a free living stage and show a broad range of host specificity in one life cycle? Genomics has already helped us to get the molecular expression profiles of many organisms. But to understand how all the information obtained at the molecular level fits into the scheme of things, we need a sound foundation in zoology. It is all the more fun studying zoology now with so many interesting questions to ask and ideas to explore.     

生物学教师在素质教育中的视野

"生物科学将成为二十一世纪的领先科学.我国自然科学的研究工作,已将生物科学列为各项重点研究与发展领域之首".(--<生物>初一课本).面对我们的学生--祖国未来的栋梁,要使他们在德智体美劳诸方面都得到发展,打好全面素质基础,适应未来社会生活的需要,适应二十一世纪祖国建设的需要,首先要转变我们自己的观念,要变"应试教育"为"素质教育",把<生物>教学工作的奋斗目标放到学生全面素质的提高上来,把我们的视野放到为学生个人负责的高度上,放到为家庭、社会、民族负责的高度上.     

基础教育生物课程改革探索

1前期准备 1.1参加全国基础教育课程改革培训班的培训 于2000年6月14日～19日赴北京参加了全国基础教育课程改革培训班的培训,主要内容有:国家基础教育课程改革介绍、现代课程观与当前我国课程改革、课程计划、课程标准与教科书简介、新课程中学与教的变革、学校课程建设、新课程与评价制度改革、实验区如何组织好通识研修等,生物课程标准研修,并听了关于科学探究式教与学的思考讲座,翻阅了实验教科书,并对几种教科书进行了对比.     

运用现代教育技术 优化生物学教学

教育技术是现代教育学的一个重要概念。随着计算机技术的迅猛发展,以多媒体技术为核心的现代教育技术进入中学课堂,已成为学校教育现代化的重要模式,也是生物学课堂教学改革的重要课题。     

美国生物学教师协会生物学教师教育项目评价

美国本土至今已有超过9000名生物学教育工作者参加美国生物学教师协会，并且与来自全球的同仁共享教学经验与技术。美国生物学教师协会也为广大的生物学教育工作者和学生开设各种栏目和项目介绍并提供易行的生物学教育。其中，为训练中学生物学教师的生物学教育项目具有特殊意义。生物学教师教育项目有两个目的，一是为了提高初中和高中生物学教师的教学指导水平，二是训练大学和学院的学生们将来能从事初中和高中的生物学教学。教学技能的职前培训是十分必要的。一名合格的中学生物学教师，不但要具有渊博的生物学专业知识，而且还应有熟练的教学技能。     

实现从就业教育到创业教育的转变

创业是解决社会就业问题的根本出路,因此高等教育要从就业教育走向创业教育;要从重视知识传授向重视培养基本素质和基本技能转变;要从重视死记硬背向重视学会认知和独立思考转变;要从重视课堂教学向重视活动课题和实践锻炼转变。同时,大学生要学会正确处理就业和创业的关系。

Learning to improve: using writing to increase critical thinking performance in general education biology

Increasingly, national stakeholders express concern that U.S. college graduates cannot adequately solve problems and think critically. As a set of cognitive abilities, critical thinking skills provide students with tangible academic, personal, and professional benefits that may ultimately address these concerns. As an instructional method, writing has long been perceived as a way to improve critical thinking. In the current study, the researchers compared critical thinking performance of students who experienced a laboratory writing treatment with those who experienced traditional quiz-based laboratory in a general education biology course. The effects of writing were determined within the context of multiple covariables. Results indicated that the writing group significantly improved critical thinking skills whereas the nonwriting group did not. Specifically, analysis and inference skills increased significantly in the writing group but not the nonwriting group. Writing students also showed greater gains in evaluation skills; however, these were not significant. In addition to writing, prior critical thinking skill and instructor significantly affected critical thinking performance, whereas other covariables such as gender, ethnicity, and age were not significant. With improved critical thinking skill, general education biology students will be better prepared to solve problems as engaged and productive citizens.

在教学中渗透创新教育初探

时代和社会的发展对人才培养的内容及价值取向都提出了新的要求并赋予了新的内涵 ,其核心就是教育对人的创新精神的培植和创新能力的挖掘 ,以造就出全能型的有创造力的人才。笔者在生物学教学过程中 ,对创新教育的渗透进行了一些有益尝试。1　捕促闪光点 ,肯定学生的创新动机对学生来说 ,只要不墨守成规 ,能别出心裁 ,标新立异地提出合乎事物发展规律的新观点、新设想、新方法都属于创新。在教学过程中 ,常遇到学生一些有创意的提问 ,比如在学习有关生物进化的证据———马化石的知识时 ,就有学生发现并提出了问题 :“生物进化的顺序是由简…     

论生命化教学设计

生命化教学是当前我国新课程教学改革提出的一种新的教学理念,也是一种以学生的生命发展为基础,关注学生的生存状态,丰富学生精神生活,赋予教学以生活意义和生命价值的新的教学模式。为了使生成性教学的理念得到落实,必须设计以人为本的教学目标、动态生成的教学内容、鲜活生动的教学资源、对话建构的教学策略和体验感悟的学习活动。
