Research Design • Pre-Experimental Design • One group of 26 non-randomly assigned students, with no controlled group. This experimental design may also be referenced as the One-Group Pre-test/ Post-test Design. • Symbolic Design: OXO • The single group of participants (O) will be pre-tested before being given the treatment (X), and a post-tested (O) in order to determine the experiment’s success.
Proposed Data • Pre-test and Post-test: Teacher administers a pre-test at the beginning of the lesson. Teacher will then administer the lesson, and give the children the same test as a post-test to see what knowledge has been obtained through the lesson. • Student Survey: Teacher gives each student the same survey which looks at personal opinions, student habits, and student demographic data.
Threats To Internal Validity • History: Unforeseen schedule changes/ student or teacher absences • Maturation: Six weeks of exposure, possible growth • Testing/Pre-test Sensitization: Pre-test offers a glimpse of what to look for during lesson • Instrumentation: Tools created by researcher, possible bias based upon student knowledge • Mortality: Student absences/ Guardian requests student no longer participates. • Differential Selection of Subjects: Drama not offered at school, does not take place in the homes • Selection-Maturation Interaction: Student maturity and growth differs • Generalizable Conditions: Student interest in dramatic arts will vary
Threats To External Validity • Pre-test Treatment: Pre-test given, students may try to memorize information • Specificity of Variables: Researcher did not influence gender selection, social studies lessons vary on type of dramatic role-play that can be implemented. • Experimenter Effects: Researcher previously worked with experimental group (students), biased questions could be created.
Sample Student Survey Questions I study for school studies ______________ hours a week. 1 hours 2 hours 3 hours 4 or more hours It is important to learn about the history of New York. Strongly Agree (4) Agree (3) Disagree (2) Strongly Disagree (1) I am a smart student and I work hard in school. Strongly Agree (4) Agree (3) Disagree (2) Strongly Disagree (1)
Correlation Of Post-test Averages To Personal Opinion Of NY Historical Importance .rxy= - 0.1507
Correlation Of Post-test Averages To Hours Studied Per Week (Social Studies) .rxy= -0.2917
Correlation Of Post-test Averages To Personal Attitude Of Work Ethics and Intelligence .rxy= -0.1889
