Educational Research: Introduction to the Concept EDU 8603 Educational Research Richard M. Jacobs, OSA, Ph.D.
Research... • The systematic application of a family of methods employed to provide trustworthy information about problems …an ongoing process based on many accumulated understandings and explanations that, when taken together lead to generalizations about problems and the development of theories
The basic steps of research... Scientific and disciplined inquiry is an orderly process, involving: recognition and identification of a topic to be studied (“problem”) description and execution of procedures to collection information (“method”) objective data analysis statement of findings (“results”)
Types of research... Basic… …the process of collecting and analyzing information to develop or enhance a theory
Applied… …conducted for the purpose of applying or testing theory and evaluating its usefulness for solving problems
Evaluation… …concerned with making decisions about the quality, effectiveness, or value of programs, products, or practices
The research continuum… field laboratory evaluation research pure research APPLIED BASIC current problems theory development what works why it works produces concepts provides data
Approaches to reasoning... Inductive… …developing generalizations from a limited number of specific observations or experiences …highly dependent on the number and representativeness of the specific observations used to make the generalization
Deductive… …developing specific predictions from general principles, observations, or experiences …dependent on the truth of the generalizations used as a basis for its logic
Relating reasoning with research methods… laboratory work field work evaluation research pure research QUALITATIVE QUANTITATIVE researcher intersubjectivity researcher objectivity post-structuralism: depth logical positivism: factual “snapshot” “portrait”
Research methods... Quantitative… …collects and analyzes numerical data obtained from formal instruments
Qualitative… …collects and analyzes nonnumeric data over an extended period of time to situate meaning within a particular perspective or context
Quantitative methods... • descriptive research (“survey research”) • correlational research • causal-comparative research (“ex post facto research”) • experimental research
descriptive research (“survey research”) …collects data in order to answer questions about the current status of the subject or topic of study …uses formal instruments to study preferences, attitudes, practices, concerns, or interests of a sample
correlational research …determines whether and to what degree a relationship exists between two or more variables …the presence of a correlation does not indicate a cause-effect relationship primarily due to multiple confounding factors
Correlation coefficient (r)… -1.00 0.00 +1.00 strong positive strong negative no relationship
causal-comparative research (“ex post facto research”) …at least two different groups are compared on a dependent variable or measure of performance (called the “effect”) because the independent variable (called the “cause”) has already occurred or cannot be manipulated
Variable... …a concept (e.g., intelligence, height, aptitude) that can assume any one of a range of values
Research variables... Independent… …an activity or characteristic believed to make a difference with respect to some behavior …(syn.) experimental variable, cause, treatment
Dependent… …the change or difference occurring a a result of the independent variable …(syn.) criterion variable, effect, outcome, posttest
experimental research …the researcher selects participants and divides them into two or more groups having similar characteristics and, then, applies the treatment(s) to the groups and measures the effects upon the groups
Quantitative method decision tree… Is there a cause-effect relationship? YES NO Is the independent variable manipulated? Is there a relationship or prediction being made? YES NO YES NO Experimental Causal-Comparative Correlational Descriptive
Qualitative methods... • historical research • grounded theory • ethnography • phenomenology • ethology • case study • ethnomethodology • action research • symbolic interaction
historical research …studies available data to study, understand, and interpret past events
ethnography …studies cultural patterns and perspectives of participants in their natural settings
ethology …compares the origins, characteristics, and culture of different societies
ethnomethodology …studies how people make sense of their everyday activities in order to behave in socially accepted ways
symbolic interaction …investigates how people construct meaning and shared perspectives by interacting with others
grounded theory …investigates how inductively-derived theory about phenomenon is grounded in the data of a particular setting
phenomenology …considers how the experience of particular participants exhibits a unique perspective
case study …examines the characteristics of a particular entity, phenomenon, or person
action research …practitioner-based systematic reflection upon practice aimed at improving professional practice
Generally speaking, qualitative researchers…. …spend a great deal of time in the settings being studied (fieldwork) …rely on themselves as the main instrument of data collection (subjectivity; intersubjectivity) …analyze data using interpretative lenses
…employ expressive language and voice in descriptions and explanations …seek depth of perspective (i.e., “waves of data” requiring ongoing interpretation) …judged in terms of believability, trustworthiness, coherence, and logic of interpretations
Types of criticism... Internal… …evaluates the worth or trustworthiness of the content of the data External… …assesses the authenticity of the data source
data sources… …primary …secondary …tertiary
Limitations of the scientific and disciplined inquiry approach… • not able to investigate philosophical and/or moral/ethical problems (“shoulds” and “oughts”) only factual matters • the presence of intervening and confounding variables make assertions probable rather than proven • imperfections in sampling, instruments, procedures
Mini-Quiz… • Identify the research methodology… …a study of the research on the effect of anxiety on achievement from 1900 to 1990 historical
…a study of the effect of socioeconomic status on self-concept causal-comparative
…a study to compare the achievement of two groups: one group taught in an anxiety-producing environment and one group taught in an anxiety reducing environment experimental
…a study of the personal and educational interactions in a group of teachers developing social studies standards for a high school curriculum qualitative
…a study to compare the achievement of a group of students classified as high-anxious and a group classified as low-anxious causal-comparative
…a study of the effect of large-group versus small-group instruction upon achievement experimental
…a study of SAT preparation by three students, with particular emphasis on their anxiety qualitative
…a study to determine the relationship between scores on an anxiety scale and scores on an achievement measure correlational
