Reading is fundamental to science and not an adjunct to its practice. In other words, understanding the meaning of the various forms of written discourse employed in the creation, discussion, and communication of scientific knowledge is inherent to how science works. The language used in science, however, sets up a barrier, that in order to be overcome requires all students to have a clear understanding of the features of the multimodal informational texts employed in science and the strategies they can use to decode the scientific concepts communicated in informational texts. We argue that all teachers of science must develop a functional understanding of reading comprehension as part of their professional knowledge and skill. After describing our rationale for including knowledge about reading as a professional knowledge base every teacher of science should have, we outline the knowledge about language teachers must develop, the knowledge about the challenges that reading comprehension of science texts poses for students, and the knowledge about instructional strategies science teachers should know to support their students’ reading comprehension of science texts. Implications regarding the essential role that knowledge about reading should play in the preparation of science teachers are also discussed here.  相似文献

Reading is a communication process that is crucial to students in science. Printed text materials are the most widely used teacher aids in the classroom. But reading as a major focus of science instruction has been out of favor with the mainstream of science education since the late 1950s. Despite this, few would deny the value of reading skills in a science class. The purpose of the present investigation was to determine how the use of Newsday's Science Education Series Program affected selected ninth-grade students' comprehension of science reading material. Analysis of covariance showed that students with standardized reading and mathematics scores at least two years above grade level who were taught using newspaper science articles alone had Degrees of Reading Power posttest scores higher at the 0.05 level of significance compared to students taught using Newsday's Science Education Series Program or using only the science article's content as part of class lessons. Students with standardized reading and mathematics scores on grade level taught using Newsday's Science Education Series Program had Degrees of Reading Power posttest scores higher at the 0.01 level of significance compared to students taught by either of the other methods.  相似文献

Treatment of surfaces to change the interaction of fluids with them is a critical step in constructing useful microfluidics devices, especially those used in biological applications. Silanization, the generic term applied to the formation of organosilane monolayers on substrates, is both widely reported in the literature and troublesome in actual application for the uninitiated. These monolayers can be subsequently modified to produce a surface of a specific functionality. Here various organosilane deposition protocols and some application notes are provided as a basis for the novice reader to construct their own silanization procedures, and as a practical resource to a broader range of techniques even for the experienced user.  相似文献

水是H1.5O?     
JRMinkel 《科学中国》2003,(12):16-16
水是什么时候不是H2O?答案是:当它是H1.5O时.1995年德国和英国物理学家用高能中子轰击水分子来观测质子的行为,发现散射的中子比预期减少了25%,这说明有1/4的氢核子(质子)不见了.  相似文献
