Assessing and Recommending Quantitative Research Designs Coursework

Assessing and Recommending Quantitative Research Designs - Coursework Example This is to say that at the beginning of the quasi experimental design, the researcher would often have a set of hypotheses in mind. These hypotheses are further broken down to give rise to dependent and independent variables. Once these dependent and independent variables are outlined, the researcher designs an intervention to use to drill for the achievement of the hypothesis. It would therefore take a pretest to give the researcher a fair idea of the current situation as hypothesized and then a posttest to get a true indication of whether or not the hypothesis materialized (Wade et al., 2009). The structure of the hypothesis, independent variable, dependent variable, and intervention above informed the rationale for the researcher’s choice of using a quasi experimental design. This is because with the quasi experimental design, the researcher was offered the advantage of critically manipulating all of the hypothesis, independent variable, dependent variable, and intervention into coming out with a conclusive study (Tanigoshi, et al., 2008). This is because the researcher would have to undertake a pretest to know the current academic grading of respondents, who would of course be members of a given university. Leading on, the researcher would have to apply the intervention, which would be the start of an extra classes segment. This would subsequently conform to the achievement of the independent variable, which is a 2-tier curriculum. Then after the intervention has been applied for a while, the researcher would have to undertake a posttest to test for the dependent variable, which is improved academic grading. In effect, the rationale for recommending a quasi experimental design was in the fact that it offered the opportunity to put all of the hypothesis, independent variable, dependent variable, and intervention to an integrated

Discuss with examples the sociolinguistic notions of linguistic Essay

Discuss with examples the sociolinguistic notions of linguistic heterogeneity and linguistic homogeneity in the speech community - Essay Example First of all, let us define sociolinguistic notions of a speech community, linguistic heterogeneity and linguistic homogeneity and then proceed to the examples of linguistic heterogeneity and linguistic homogeneity in a speech community within the context of sociolinguistics. It must be noted that the definition of speech community sparks controversy among notable linguists to date. Early definitions of a speech community proceeded from the basis that a speech community is a group of people residing within the area of compact settlement, which is densely inhabited by those who share the same vernacular language and tend to use the same standardized language for communication. According to the notable American linguist, William Labov, who is regarded to be the father of such discipline as variationist sociolinguistics, a speech community is a group of people who share the same language norms that do not depend on social context changes.1 However, it is important to understand that the dependence of a language on social processes can be manifested in a set of different language subsystems (i.e. forms of existence and functioning of a specific language), bilingualism or diglossia, availability or nonexistence of a written language, language policy, etc. These are important but not exclusive manifestations of the connection between a language and conditions of its functioning. Lexicon, grammatical structure and the evolution of linguistic styles exert a substantial influence upon the use of language within a speech community as well. A speech community tends to share a certain set of norms of the language use, which is manifested in the process of communication within the framework of a certain group of people who are bounded by the same lifestyle, profession, interests or represent the same social stratum, which resulted in a long-term delusion, according to which a speech community is always characterized by linguist ic homogeneity. However,
