Effects of active‐learning experiences on achievement,attitudes, and behaviors in high school biology

Active‐learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab‐based activities, with active‐learning labs compared to traditional instruction. In‐class test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab‐based curriculum indicated that they perceived changing their behaviors as intended by the student‐centered principles of the labs. The major implication of this study is that active‐learning–based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student‐centered instructional practices as well as enhanced content knowledge and process learning for students. © 2007 Wiley Periodicals, Inc.

Towards logical designs in biology     

Garima Agarwal 《Resonance》2007,12(2):29-38

This article highlights an emerging field known as synthetic biology that envisions integrating designed circuits into living organisms in order to instruct them to make logical decisions based on the prevailing intracellular and extracellular conditions and produce a reliable behavior. The attempt is to design cells capable of sensing a bioweapon or an environmental pollutant, activate its degradation pathway and perform bioremediation or carry out programmed cell death or synthesize complex biomaterials. Within the living cell, a complex interplay of networks formed by genes and proteins mediate all cellular processes. The networks in a system can be dissected into small regulatory gene circuit modules. Synthetic biology attempts to construct and assemble such modules step by step, plug the modules together and modify them, in order to generate a desired behavior. The review gives an insight into the creation of gene circuits and discusses the potential applications in the field of biotechnology, medicine and environmental sciences. Garima Agarwal is a research student in the Molecular Biophysics Unit, Indian Institute of Science. Her areas of research interest include structural biology, bioinformatics and systems biology.  相似文献

《生态学研究方法》是2017年海南大学研究生精品课程和特色课程建设的试点对象之一。该课程存在教学内容陈旧、实践和创新性思维培养不足和考核方式单一等问题。通过组建授课教师组队伍、丰富教学内容、改进教学和考核方式等措施,结合海南大学生态学学科的区域特色和研究生培养目标,使得该课程有了一个质的提高。课程授课内容将紧密围绕4个主要研究方向(理论与进化生态学、生态系统生态学、环境生态学和资源生态学)来开展,有利于培养具有区域特色的生态学高层次人才。  相似文献   

Knowledge Restructuring in Biology: Testing a Punctuated Model of Conceptual Change     

Joel Mintzes  Heather J. Quinn 《International Journal of Science and Mathematics Education》2007,5(2):281-306

Emerging from a human constructivist view of learning and a punctuated model of conceptual change, these studies explored differences in the structural complexity and content validity of knowledge about prehistoric life depicted in concept maps by learners ranging in age from approximately 10 to 20 years. Study 1 (cross-age) explored the frequencies of concepts, relationships, levels of hierarchy, branching, and cross-links in concept maps drawn by students in grades 5, 8, 11, 13, and 14. The results provide some support for a punctuated model of conceptual change. Study 2 (longitudinal) explored the same frequencies on repeated occasions among students enrolled in a college course on prehistoric life, and documented the shift in frequencies of “novice” and “expert” concepts occurring during the semester. The results suggest that college students engage in much restructuring of their knowledge frameworks during the period of a semester. Together, the two studies raise questions about common classroom practices that encourage the rote learning of biology and geology concepts at all levels.  相似文献

加强生物思想教育 提高学生的思想水平     

付安平 《教育学报》2001,(9):29-31

目前普通教育较侧重知识教育,不太注意能力培养,思想教育则更是空白,因此,学生思想素质很难上台阶,为了提高学生的思想水平,造就大批高素质的跨世纪人才,我们必须站在新的高度认识生物学科教学,加强生物思想教育,提高学生的思想水平,本文从七个方面论述了生物思想教育,从而使生物学科教学更适应时代的要求.  相似文献
