Newton’s law of universal gravitation laid the physical foundation of celestial mechanics. This article reviews the steps
towards the law of gravitation, and highlights some applications to celestial mechanics found in Newton’sPrincipia.
His research interests cover all types of cosmic explosions and their remnants. 相似文献

The prevailing scholarship on Indians’ beliefs about English has, with few exceptions, largely failed to capture ideological resistance. Given the supremacy of English within the hierarchically ordered and unequal linguistic landscape in India, this study intervenes within this limited area of research. This investigation excavates ideologies of resistance to English through chutkule, a humorous folk genre, narrated by young boys at an anathashram (orphanage) in suburban New Delhi. The theoretical lens of language ideology is employed to unpack latent issues of resistance and erasure within the chutkule, and emergent ideological tensions are interpreted in the context of educational equity. In addition to locating beliefs about language in a previously unresearched genre, this study adds to the limited scholarship on Indians’ ideological resistance to English. Further, because these notions are mined through the boys’ chutkule at the anathashram, this investigation illuminates previously neglected discourses from India’s socioeconomic margins. 相似文献

The above account reveals the versatility of Prafulla Chandra’s research activities. Most importantly, he initiated chemical research in modern India and was successful in developing the first research school of chemistry that in time spread far and wide. In his obituary notice,Nature (July 15, 1944) wrote “it was by the enthusiasm for research with which he inspired his students that he will best be remembered”. 相似文献

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. 相似文献

INTRODUCTION Tomato (Lycopersicon esculentum, Mill.), an important vegetable crop is heavily attacked by root knot nematode, Meloidogyne spp. For the manage-ment of root knot nematodes although chemical nematicides were used till 1982, due to their high cost, toxic effect on beneficial soil borne microorganism and carcinogenic effect on human beings alternative approaches are practiced mainly through eco-friendly means like biological control agents, organic amendments, etc. (Singh and … 相似文献

Preparation for lifelong learning using ePortfolios 总被引：1，自引：1，他引：1
Rapid technological change, increasing globalization and a changing world of employment with multiple roles during one's professional life are necessitating a change from knowledge to learning societies. Full participation requires lifelong learning skills, meaning the ability to solve problems, work both independently and in a team, communicate effectively in all formats and on all levels, and self-direct one's learning and professional development needs. Universities need to take responsibility in preparing students for lifelong learning. While engineering and science degrees traditionally do not emphasize the importance of lifelong learning skills new programmes of study are now being introduced, often using electronic portfolios to support engagement with learning objectives and reflection. This article describes an electronic portfolio initiative that is targeted at engineering and computer science students. The initiative aims to create awareness among students on the nature and importance of lifelong learning skills, to facilitate the development of such skills and to assist students in showcasing their competence regarding these skills. Interviews with industry representatives regarding the characteristics of a lifelong learner and the values of constructing and presenting portfolios were conducted and have resulted in strong support for the electronic portfolio initiative. The article provides background on lifelong learning and electronic portfolios, outlines the design of the initiative and then focuses on feedback from industry representatives. 相似文献

Developing scientific literacy about water systems is critical for K-12 students. However, even with opportunities to build knowledge about the hydrosphere in elementary classrooms, early learners may struggle to understand the water cycle (Forbes et al., 2015 ; Gunckel et al., 2012 ; Zangori et al., 2015 ; Zangori et al., 2017 ). Scientific modeling affords opportunities for students to develop representations, make their ideas visible, and generate model-based explanations for complex natural systems like the water cycle. This study describes a comprehensive evaluation of a 5-year, design-based research project focused on the development, implementation, revision, and testing of an enhanced, model-centered version of the Full Option Science System (FOSS) Water (2005) unit in third grade classrooms. Here, we build upon our previous work (Forbes et al., 2015 a; b; Vo et al., 2015 ; Zangori et al., 2015 ; Zangori et al., 2017 ) by conducting a comparative analysis of student outcomes in two sets of classrooms: (1) one implementing the modeling-enhanced version of the FOSS Water unit developed by the research team (n = 6), and 2) another using the standard, unmodified version of the same curricular unit (n = 5). Results demonstrate that teachers in both conditions implemented the two versions of the curriculum with relative fidelity. On average, students exposed to the modeling-enhanced version of the curriculum showed greater gains in their model-based explanations for the hydrosphere. Engagement in scientific modeling allowed students to articulate hydrologic phenomena by (1) identifying various elements that constitute the hydrosphere, (2) describing how these elements influenced the movement of water in the hydrosphere, and (3) demonstrating underlying processes that govern the movement of water in the hydrosphere. 相似文献

Adolescents with word-reading skills below grade level were randomly assigned to one of three conditions. Those receiving interventions practiced reading 100 multisyllabic words, either by analyzing graphosyllabic units in the words or by reading the words as unanalyzed wholes. The third group received no special instruction. Posttests revealed that graphosyllabic instruction helped students to decode novel words, remember how to read words with practice, and remember the spellings of words when compared to controls. In contrast, whole-word instruction yielded no benefit on transfer tasks compared to controls. Effects were observed primarily among adolescents reading at a third-grade-equivalent level and less so at a fourth- and fifth-grade-equivalent level. Results are consistent with a connectionist view of word learning and indicate the importance of providing struggling readers with instruction and practice in how to fully analyze the graphosyllabic constituents of words. 相似文献
