Beware the Pitfalls

Quantitative measures aim to explain causal relationships—though most often, in social science research, these methods can only determine correlations between the different factors studied, not make definite predictions about the universality of their application Creswell, A quantitative study in the social sciences follows the prescriptions of the scientific method: Reproducibility is foundational to quantitative experimentation; if a study cannot be reproduced by others, or by the same researcher at a later time, by definition it does not follow the constructs of the scientific method.

Because quantitative analysis applies mathematical equations to collected data to make the analysis objective, the social sciences researcher must be particularly attentive to the collection of non-biased data Sax, If the data is biased, statistical analyses might lead to false or inaccurate theories or predictions.

In the life or physical sciences, collecting neutrally biased information is less challenging than in educational research, as measurements of widths of cells and of electron transport, for example, have been standardized. In educational research, however, particular care must be paid to the way in which an investigator's biases may lead to the collection of a specific kind of information, or to a particular sampling method that might not fairly represent the population in question Creswell, Because all researchers hold values, qualitative education researchers have criticized quantitative studies since the late twentieth century for being only marginally useful in determining the "objective truth" of life in the classrooms or of methods of curriculum construction Pinar et al, In addition to concerns of reliability and bias, quantitative research must also be accurate and valid.

Accuracy refers to the extent to which the experimental results accord with theoretical models, or the extent to which empirical results measure the phenomenon in question. Validity in the social sciences can be assessed in three ways: Content validity refers the suitability of a study's data collection and analysis methods for the questions being investigated. Criterion validity refers to whether a study uses previously validated methods or, if it is novel in its approach, it has predictive value.

Quantitative research in curriculum construction and evaluation grew out of the common school movement in the nineteenth century and, though popular in the early to mid-twentieth century, drew increasing criticism into the late twentieth and early twenty-first centuries Pinar et al, However, at about the time it was losing popularity with educational researchers, quantitative research gained new importance in the newly developed field of education policy studies.

The movement toward accountability, toward assessing "learning gaps" between various groups, toward increasing the efficiency and effectiveness of policy implementations—along with the increasing role of the federal government and of national organizations in education—was founded upon quantitative analysis Heck, The quality of quantitative research in education has been harshly criticized, however, and it remains a matter of concern for policy analysts and quantitative researchers.

Some common critiques are that educational researchers are not adequately trained to approach social problems quantitatively, and that researchers often dismiss as irrelevant data that does not seem to match the expected results, offering explanations, after the fact, of why this data was not included in the final analysis Sax, ; Heck, Even quantitative researchers have posed these critiques.

They continue to advise policy makers, students of education, and professionals in the field of the importance of critically appraising a quantitative educational study before relying on its analyses. Quantitative research in education grew out of the common school movement in the nineteenth century.

The common school, a term coined by educational advocate and reformer Horace Mann — , was a government-funded free school in which any child from any socioeconomic background or status could enroll. The movement formed the foundation for modern day public education Travers, The establishment of common schools ushered in an era of educational management.

The educators of the time, whose names remain well known today, were generally involved not directly in teaching, but rather in making educational policies, effectively governing boards of education, advising and consulting with principals and teachers, and founding educational journals and conferences. These management decisions relied on adequate, accurate quantitative descriptions of school enrollment and retention rates, of effective organizational structures, and of a variety of other matters thought to correlate to a school's efficiency and productivity Pinar et al, The quantitative movement soon permeated the curriculum field, and educational theorists became increasingly interested in using scientific methods to measure and improve curriculum construction.

Edward Thorndike — was an American psychologist who is credited as the leader of this movement toward quantifying curriculum Travers, He emphasized the importance of establishing "facts;" once these basic facts are discovered, Thorndike wrote, one would have a grasp of a field of knowledge. Among these issues included the characteristics of workplace bullies, and coping Reponses. The article suggests that workplace bullying is a serious issue for social workers and needs to create guidelines and tools to help stop bullying behaviors Whitaker, T.
