From Music to Physics: The Undervalued Legacy of Pythagoras     

Imelda Caleon  Subramaniam Ramanathan 《Science & Education》2008,17(4):449-456

This paper presents the early investigations about the nature of sound of the Pythagoreans, and how they started a tradition that remains valid up to present times—the use of numbers in representing natural reality. It will touch on the Pythagorean notion of musical harmony, which was extended to the notion of universal harmony. How the Pythagorean ideas have inspired many great works in physics, such as those of Galileo, Kepler and Newton, will also be presented. In exploring the legacy of Pythagoras to physics and the study of the universe, some valuable insights on the nature of science that can inspire budding physicists are extracted.  相似文献   

First-Year College Students’ Conflict with Religion and Science   总被引：1，自引：1，他引：0  

Lisa Michelle Martin-Hansen 《Science & Education》2008,17(4):317-357

This study took place during a First Year Seminar course where 20 incoming college freshmen studied the central topic of the nature of science within the context of biological evolution. The instructor researched students’ understandings in the nature of science as they progressed through the course by examining a variety of qualitative and quantitative data including class writings, pre- and post-test selected items from the VOSTS (Views on Science-Technology-Society), and interviews. The intended outcomes of the course were to reduce the number of student misconceptions in the nature of science and to ease student apprehension when learning about evolution. Data were analyzed to determine whether students were moving toward a more generally accepted idea of the nature of science or toward another type of misconception.  相似文献

Multicultural Visions of Globalization: Constructing Educational Perspectives From the East and the West     

Stephen R. White 《Interchange》2008,39(1):95-117

The thesis of this essay is that globalization is a phenomenon that humankind must be educated for understanding as a process of global evolution. The new world evolving is being defined as requiring a new sense of collective cooperation amongst the peoples of the Earth, if we are to continue to exist on the planet. Educators are in the midst of and have an important role to play in this social and conscious evolution. One of our challenges is to explore the theoretical foundations for framing a new global education agenda. The assertion is that the theories of global, social, and conscious evolution of 20^th century intellectuals and visionaries such as India’s Sri Ghose Aurobindo (1872-1950) and France’s Pierre Teilhard de Chardin (1881-1955) provide the foundation from which to construct a new global educational perspective.  相似文献

Classroom     

P. Jayanth Vyasanakere  K. Sudeesh 《Resonance》2008,13(8):768-771

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science. This project was done as part of the Research Education Advancement Programme held over weekends at the Bangalore Association for Science Education, Jawaharlal Nehru Planetarium, Bangalore.  相似文献   

Effects of organizational pictures and modality as a feedback strategy on learner comprehension and satisfaction     

Albert D. Ritzhaupt  Raymond Pastore  Jiahui Wang  Robert O. Davis 《Educational technology research and development : ETR & D》2018,66(5):1069-1086

One of the strongest instructional interventions documented in educational literature is the use of feedback to influence learning outcomes. However, there is lack of empirical research specifically pertaining to the use of multimedia in the feedback message. The purpose of this research was to test whether organizational pictures and modality as a feedback strategy had an effect on learner comprehension and satisfaction. The research design was a 2 Multimedia (Picture Present vs. Picture Absent) × 2 Modality (Narration vs. On-screen Text) × Trial (Trial 1 vs. Trial 2) with Multimedia and Modality serving as between-subject conditions and Trial serving as a repeated measure. One-hundred fifteen university students participated in the study. Findings show statistically significant increases in comprehension scores from Trial 1 to Trial 2 assessments for all four treatment conditions. Learners in the Picture present conditions were statistically more satisfied with the learning experience. Additionally, we used eye-tracking to verify the extent to which the pictures were used in the feedback message. A discussion and recommendations for future research and feedback design are provided.  相似文献   

Tea polyphenols dominate the short-term tea (<Emphasis Type="Italic">Camellia sinensis</Emphasis>) leaf litter decomposition     

Dong-mei Fan  Kai Fan  Cui-ping Yu  Ya-ting Lu  Xiao-chang Wang 《Journal of Zhejiang University. Science. B》2017,18(2):99-108

Polyphenols are one of the most important secondary metabolites, and affect the decomposition of litter and soil organic matter. This study aims to monitor the mass loss rate of tea leaf litter and nutrient release pattern, and investigate the role of tea polyphenols played in this process. High-performance liquid chromatography (HPLC) and classical litter bag method were used to simulate the decomposition process of tea leaf litter and track the changes occurring in major polyphenols over eight months. The release patterns of nitrogen, potassium, calcium, and magnesium were also determined. The decomposition pattern of tea leaf litter could be described by a two-phase decomposition model, and the polyphenol/N ratio effectively regulated the degradation process. Most of the catechins decreased dramatically within two months; gallic acid (GA), catechin gallate (CG), and gallocatechin (GC) were faintly detected, while others were outside the detection limits by the end of the experiment. These results demonstrated that tea polyphenols transformed quickly and catechins had an effect on the individual conversion rate. The nutrient release pattern was different from other plants which might be due to the existence of tea polyphenols.  相似文献
