No matter how much we may try to ignore it, human communication always takes place in a context, through a medium, and among individuals and groups who are situated historically, politically, economically, and socially. This state of affairs is neither bad nor good.

Teaching word meanings should be a way for students to define their world, to move from light to dark, to a more fine-grained description of the colors that surround us. Baker, Simmons, and Kame'enui1 state, "The relation between reading comprehension and vocabulary knowledge is strong and unequivocal.

Although the causal direction of the relation is not understood clearly, there is evidence that the relationship is largely reciprocal. However, not all approaches to teaching word meanings improve comprehension.

This chapter will describe some of the most practical and effective strategies that high-school teachers can employ with diverse learners Rationale in research enhance vocabulary development and increase reading comprehension. Instructionaland curricular basics and implications.

Lawrence Erlbaum Associates,pp. There are a number of traditional teaching practices related to vocabulary that deserve to be left in the "instructional dustbin. Let us quickly review the most common of these less effective approaches.

Certainly dictionaries have their place, especially during writing, but the act of looking up a word and copying a definition is not likely to result in vocabulary learning especially if there are long lists of unrelated words to look up and for which to copy the definitions.

Use them in a sentence. Writing sentences with new vocabulary AFTER some understanding of the word is helpful; however to assign this task before the study of word meaning is of little value. There is little research to suggest that context is a very reliable source of learning word meanings.

Nagy3 found that students reading at grade level had about a one twentieth chance of learning the meaning of a word from context. This, of course, is not to say that context is unimportant but that students need a broader range of instructional guidance than the exhortation "Use context.

Rote learning of word meanings is likely to results, at best, in the ability to parrot back what is not clearly understood.

Vocabulary learning, like most other learning, must be based on the learner's active engagement in constructing understanding, not simply on passive re-presenting of information from a text or lecture. Reviewing the research literature on vocabulary instruction leads to the conclusion that there is no single best strategy to teach word meanings but that all effective strategies require students to go beyond the definitional and forge connections between the new and the known.

Nagy3 summarizes the research on effective vocabulary teaching as coming down to three critical notions: The following section will explore some practical strategies that secondary teachers can employ to increase the integration, repetition, and meaningful use of new vocabulary.

Increase the Amount of Independent Reading The largest influence on students' vocabulary is the sheer volume of reading they do, especially wide reading that includes a rich variety of texts. This presents a particularly difficult challenge for underprepared high-school students who lack the reading habit.

The following strategies can help motivate reluctant readers: Matching text difficulty to student reading level and personal interests e. Choose Appropriate Dictionaries for Heterogeneous Classrooms Secondary students certainly need to know how and when to use a dictionary to look up the meanings of unfamiliar words.

Surprisingly, many adolescents lack even the most rudimentary dictionary skills and benefit from some explicit instruction.

Without training and guidance, less proficient readers and English language learners are apt to encounter numerous difficulties as they struggle first to locate and then to effectively navigate a lengthy dictionary entry.

Many students do not own a dictionary, and if they do, it is often not a very powerful or appropriate resource for clarifying word meanings. English learners may carry a bilingual dictionary, but this resource is generally inadequate for several reasons.

First, long-term bilinguals or more recent immigrants with disrupted educational histories may have limited academic vocabulary in the home language.Explaining the purpose of a research study and providing a compelling rationale is an important part of any coaching research project, enabling the work to be set in the context of both existing evidence (and theory) and its practical applications.

This necessitates formulating a clear research. Aug 28,  · Mainly, a rationale will need to have stated your research problem, defined the key terms, noted objectives and noted the importance of the subject.

In addition, a rationale will need to have reviewed and summarized the available literature, noted any gaps in this literature or in the study of the topic/5(64). Research has generated evidence that second-hand smoke causes the same problems as direct smoking, including lung cancer, cardiovascular disease, and lung ailments such as emphysema, bronchitis, and asthma.


Specifically, meta-analyses show that lifelong non-smokers with partners who smoke in the home have a 20–30% greater risk of lung cancer than non-smokers who live with non .

The research needs to contribute to the elimination of a gap in the literature. Why a Scientific Format? The scientific format may seem confusing for the beginning science writer due to its rigid structure which is so different from writing in the humanities.

One reason for using this format is that it is a means of efficiently communicating scientific findings to the broad community of scientists in a .
