In the last session I provided a brief overview of the experimental and ex-post facto designs. Basically here is how they differ. Are songs effective to teach listening comprehension?
You draw the sample randomly from the population. Then you assign the sample into an experimental and control groups also randomly. It emphasizes the rationale for commonly used research procedures and their applications.
The nature of educational research is outlined and the steps in the research process are clearly defined. Because identification of a research problem is so important, the entire second chapter is devoted to this topic.
It has been updated with a new chapter on evaluating research papers, additional information on computers and software used in research, and a data disk consisting of three data sets that accompanies the text. The book is broad in scope covering both quantitative and qualitative research methodologies as well as sampling designs, measurement, data collection, preparation of data sets for computer analysis, statistical procedures, and reports.
For anyone interested in the research methodology for education and educational psychology. From inside the book. Contents Its Nature and Characteristics. Identification of A Research Problem. The Review of The Literature.
Ex post facto research is ideal for conducting social research when is not possible or acceptable to manipulate the characteristics of human participants. It is a substitute for true.
Ex post facto study or after-the-fact research is a category of research design in which the investigation starts after the fact has occurred without interference from the researcher.
Ex post facto design is a quasi-experimental study examining how an independent variable, present prior to the study in the participants, affects a dependent variable. A quasi-experimental study simply means participants are not randomly assigned. Causal research uses different terms: ex post facto studies gather data retrospectively (e.g. given the obvious effects of smoking, the researcher will look in the past to find the potential cause), causal comparison where data are gathered from pre-formed groups and the independent variable is not manipulated in the experiment. For this, the researcher will have either to find a population on which .
An ex post facto research design is a method in which groups with qualities that already exist are compared on some dependent variable. Also known as "after the fact" research, an ex post facto design is considered quasi-experimental because the subjects are not randomly assigned - they are grouped. ex post facto research include the failure to recog- nize the limitations of the design, the failure to realize that an experimental approach is possible.
