Research design
Research Design Science.

  • Quasi-Experimental Design:

    Nonequivalent Control Group Design

  • Two groups of ELL students. The first group is the experimental group X1

  • The second group is the control group X2. Here the treatment will be classroom instruction.

    Both groups will receive a Pre-test and a Post-test O.

  • Symbolic Design:

  • O X1 O

  • O X2 O


Threats to internal validity
Threats to Internal Validity Science.

  • History: Any past experiences or cultural background can affect participation or involvement.

  • Maturation: Students individual attitude and experience towards Science, language skills, and computer usage may lead to loss of interest or participation.

  • Testing sensitization: Students may not take Pre-testing or post-testing seriously.


Threats to external validity
Threats to external validity Science.

  • Pretest-treatment: Pre-test scores may affect feelings towards post-test.

  • Hawthorne effect: Students may have the feeling of “being watched” and they perform according to the way they think researcher wants to find.

  • Experimental effects: Teachers may feel they need to teach for the test during this time of year.
