Language Proficiency
Language proficiency is the ability of an individual to use language with a level of accuracy that transfers meaning in production and comprehension. There is no singular definition of language proficiency: while certain groups limit its scope to speaking ability, others extend it to cover both productive and receptive language skills and their effective application in varying practical contexts. However, this diversity has implications for its application in other language domains such as literacy, testing, endangered languages, language impairment, etc. There is little consistency as to how different organizations classify it. Native-level fluency is estimated to require a lexicon between 20,000 and 40,000 words, but basic conversational fluency might require as few as 3,000 words. Developing language proficiency Developing proficiency in any language begins with word learning. By the time they are 12 months old, children learn their first words and by the time they are 36 mont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expertise
An expert is somebody who has a broad and deep understanding and competence in terms of knowledge, skill and experience through practice and education in a particular field. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credentials, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opini ...

Skill
A skill is the learned ability to act with determined results with good execution often within a given amount of time, energy, or both. Skills can often be divided into domain-general and domain-specific skills. For example, in the domain of work, some general skills would include time management, teamwork and leadership, self-motivation and others, whereas domain-specific skills would be used only for a certain job. Skill usually requires certain environmental stimuli and situations to assess the level of skill being shown and used. A skill may be called an art when it represents a body of knowledge or branch of learning, as in ''the art of medicine'' or ''the art of war''. Although the arts are also skills, there are many skills that form an art but have no connection to the fine arts. People need a broad range of skills to contribute to the modern economy. A joint ASTD and U.S. Department of Labor study showed that through technology, the workplace is changing, and id ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uncertainty Coefficient
In statistics, the uncertainty coefficient, also called proficiency, entropy coefficient or Theil's U, is a measure of nominal association. It was first introduced by Henri Theil and is based on the concept of information entropy. Definition Suppose we have samples of two discrete random variables, ''X'' and ''Y''. By constructing the joint distribution, , from which we can calculate the conditional distributions, and , and calculating the various entropies, we can determine the degree of association between the two variables. The entropy of a single distribution is given as: : H(X)= -\sum_x P_X(x) \log P_X(x) , while the conditional entropy is given as: : H(X, Y) = -\sum_ P_(x,~y) \log P_(x, y) . The uncertainty coefficient or proficiency is defined as: : U(X, Y) = \frac = \frac , and tells us: given ''Y'', what fraction of the bits of ''X'' can we predict? In this case we can think of ''X'' as containing the total information, and of ''Y'' as allowing one to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
