Comparison and Contrast between Krashen’s Input Hypothesis and Long’s Interaction Hypothesis

Foreign language learning is of crucial importance to everyone. What’s even more important is that which kind of learning strategies is used under a certain theory. This article will present an account of the two great linguists’ theories and try to investigate commons and differences between them. Doing so the author is in the hope of seeking a better learning strategy to help second language learners.     

Motivation and Second Language Learning

How to Develop the DARP-Oriented English Extracurricular Activities

Just like learning any other foreign languages, English learning needs a more authentic and effective language environment, in which learners learn for using instead of learning for learning. But the present situation in China is not very optimistic, especially in the field of middle school English teaching, English extracurricular activities, as effective methods of providing a real English environment, has not yet been taken seriously by many English teachers. Students still learn English in a deaf-and-dumb environment. Thus its necessity of fully developing seems self-evident. Parallel the contemporary problems exist in the English extracurricular activities with the necessily of developing English extracurricular activities in middle schools, it is quite clear that an effective method should be carried out to improve the efficiency of English extracurricular activities in middle schools.[第一段]

The Effective Strategies Used to Guide Students’ Reading

It is widely acknowledged that the ultimate goal of tea- ching is to help students acquire subject-matter knowledge. But accordingtoRichard E. Mayer(2003)“,apassage may be difficult to comprehend when the reader lacks an appropriate perspective or has a perspective different from that of a writ- er.”. In this sense, the teaching of learning strategies seems important in teaching process. For example, my teaching tar- gets are college students, they are often confronted with such dilemma: th…     

New Charged Charmonium-like States Observed at BESIII

<正>Since the discovery of the electrically-charged Zc(3900),a possible four-quark object,the Beijingbased BESIII Collaboration has made a rapid string of related discoveries.While quarks have long been known to bind together in groups of twos or threes,these new results seem to be quickly opening the door to a previously elusive type of four-quark matter.The most recent breakthroughs by the BESIII Collaboration have come about through a dedicated study of the decays of the mysterious"Y(4260)"particle,which has a well-established mass that is inconsistent with the interpretation that it consists only of a charm quark and     

A new approach for identifying metabolic biomakers

The idea of finding a single metabolite biomarker that can unambiguously diagnose a disease is a beguiling one, but unfortunately not currently supported by reality. Although researchers have reported the discovery of a whole range of potential biomarkers for numerous diseases, they often don＇t stand up to closer scrutiny. But now, by combining together a whole range of different analytical and statistical techniques, a team of Chinese and German chemists may just have improved the chances of detecting a proper biomarker.     

Data quantity governance for machine learning in materials scienceOA

Data-driven machine learning(ML) is widely employed in the analysis of materials structure-activity relationships,performance optimization and materials design due to its superior ability to reveal latent data patterns and make accurate prediction.However,because of the laborious process of materials data acquisition,ML models encounter the issue of the mismatch between a high dimension of feature space and a small sample size(for traditional ML models) or the mismatch between model parameters a...     

Harvest Synchronous Baby Cells from Microfluidic Channels

<正>The growth and division of bacteria are precisely regulated by a vital process known as the cell cycle. Just like the lifetime of a human being, a bacterial cell's lifetime is composed of different events that occur at different stages of the cell cycle, with the size and physiology of the cell changing as the cycle proceeds. In normal bacterial culture, cells at different stages of the cell cycle are mixed together, so it is difficult to study separate events within the cycle. To gain insight

To what extent is language teaching methodology informed by theory？

With the globalization of the world, language teaching becomes more important than ever before, and many universities and classroom teachers are active to exploret he most efficient and effective methodology to teach languages to achieve a desirable result. When they seek to improve the quality of language teaching, they often research teaching methodologies by referring to general theories about language and language learning. Theoretical bases and teachers‘ hands-out experience have informed methodologies of language teaching, and methods of language teaching have been improved with the developments about linguistics, psychology and education. But there is a question which extent the information that theory has made available can be used to explore language teaching methodology and of the relevance of theory to language teaching methodology.
