Experimental and quasi experimental methods

  1. 1. What is an experimental method? Stages of the experimental method Is the experimental method used in the education? The quasi-experimental method and examples
  2. 2. It is a method or procedure derivative from the practice and experience that consists of a systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
  3. 3.  Observation: Consists in data selection.  Hypotheses: This are the rational suppositions get from the observed data.  Hypotheses Explanation: It is the explanation of mathematics systems to the hypotheses get before.  Experimentation: Confirm or refute the hypotheses.
  4. 4. Three Important reasons:  The human being acts depend on the context.  The result of the research can be manipulated.  It is not possible generalized data.
  5. 5. Quasi-experimental research may look very much like true experimental research in that it does involve the manipulation of an independent variable. However, it is not the same as true experimental research because quasi-experimental research studies lack one or both of the essential properties of randomization and a control group. Taken from: http://www.researchproposalsforhealthprofessionals .com/quasiexperimental_research.htm  Study the effects of a program to drive a car very good.  Evaluate the effects of a program to prevent the criminal behaviors in teenagers have abandoned their house.  Investigate why do the students don’t like some subjects: mathematics, English, etc. EXAMPLES
  6. 6. EXPERIMENTAL AND QUASI-EXPERIMENTAL METHODS DATA COLLECTION TOOLS  Standardized test  Observations  Polls  Scales
