The Nature of Research What is Research? The ability to answer a question or concern facing many of us in our daily and professional lives. Scientists, engineers, doctors, teachers, counselors, administrators, parents, and students continually need to seek information in order to perform their jobs. Slide 1 How Does One Obtain Information? People do the following to obtain information: Consult experts Review books and articles Question/observe colleagues Rely on past experience Use intuition Using scientific research provides another way to obtain information Information is reliable and accurate Allows an understanding of why research is valuable Slide 2 Ways of Knowing That Things Exist Personal Experience Agreement/Sharing with Others Expert Opinion Logical Reasoning The Scientific Method Slide 3 The Scientific Method The goal of the scientific method is to explain, predict, and/or control phenomena This involves the acquisition of knowledge and the development and testing of theory The use of the scientific method is more efficient and reliable than any other source of knowledge Slide 4 The Scientific Method 5 distinct steps: State the problem Formulate of hypotheses Collect data - how to gather the information How to organize and analyze the information obtained How the information is interpreted EDS 502 Slide 5 Classification of Research Research Descriptive EDS 502 Associational Intervention Slide 6 General Research Types Descriptive studies describe a given state of affairs Associational studies investigate relationships Intervention studies assess the effects of a treatment or method on outcomes EDS 502 Slide 7 Classification of Research Research Qualitative EDS 502 Quantitative Slide 8 Quantitative Research Purpose: Collect and analyze data to explain, predict a phenomena of interest (describe current conditions, investigate relationships, study causes and effects) a positivistic perspective Characteristics Numerical data Use of formally stated hypotheses and procedures Use of controls to minimize the effects of factors Large numbers of participating subjects An objective, detached researcher Use of pencil and paper tests, questionnaires, etc. EDS 502 Slide 9 Qualitative Research Purpose: To probe deeply into the research setting to obtain in-depth understandings about the way things are, why they are like that, and how participants perceive them Characteristics There are no hypotheses guiding the researcher Problems and methods tend to evolve over the course of the study Phenomena are examined as they exist in a natural context, and they are viewed from the participants’ perspectives There are few participants involved in the study Data analysis is interpretative in nature EDS 502 Slide 10 Exercise Educational researchers have been interested in identifying ways to reduce students' test anxiety. Describe a research question that a quantitative researcher might define and one that a qualitative researcher might define to guide a literature search on this problem EDS 502 Slide 11 Sample answers Quantitative Are female math students significantly different from male math students in their level of test anxiety? What is the relative cost-effectiveness of different interventions for reducing test anxiety? Which measure of test anxiety best predicts test anxiety among high school students? EDS 502 Slide 12 Sample answers Qualititative What are the specific aspects of taking a test that create anxiety among students? How do students describe their experience of test anxiety before, during, and after a test? How do students who are high in test anxiety differ from those who are low in test anxiety in terms of their coping strategies? EDS 502 Slide 13 The Research Process Statement of the problem: description of the background and rationale for performing the study Hypothesis: prediction of what is expected to occur, or relationship expected between the variables (factors being considered) Definitions: key terms in the problem statement EDS 502 Slide 14 The Research Process (cont.) Review of Literature: past or current studies that are relevant to the study Sample: subjects of the study Instrumentation: what will be used to measure or collect data Procedures: step-by-step directions, outlining what will occur from beginning to end Data Analysis: statistical procedure to analyze and explain the data EDS 502 Slide 15 Research process (Figure 1.4) EDS 502 Slide 16
