  2. TABLE OF CONTENTS • Research Design • Threats to External Validity • Threats to Internal Validity • Proposed Data • References

  3. RESEARCH DESIGN • Pre-Experimental Design: One-Group Pretest-Posttest Design. • Single Group: Single group is pre-tested (O), exposed to a treatment (X), and posttested (O). • Symbolic Design: OXO Groups are randomly assigned.

  4. THREATS TO EXTERNAL VALIDITY Generalizable Conditions – Teaching style, or learning style. Pre-Test Treatment - Pre-testing prior to the treatment may affect test scores. Selection-Treatment Interaction – Participants were not randomly selected from the population. Specificity of Variables - Both teachers will use a scripted math program but teaching styles may vary. Multiple Treatments - Seating model over time could reduce effectiveness

  5. THREATS TO INTERNAL VALIDITY • History – Student lateness, illness, absences, weather conditions, behavioral outbursts, other disturbances (i.e. phone calls, announcements). • Maturation – Increased focus due to age and maturity. • Testing – Test format does not vary, familiarity could improve scores. • Instrumentation – Researcher created student surveys presented by two different teachers. • Selection – Two groups of students. • Mortality – Student dropouts and transfers. • Selection-Maturation Interaction - Students vary in age and gender.

  6. Proposed Data of Pretest and Posttest

  7. CORRELATION Rxy= 0.99896854 There is a positive correlation between boys who work in groups with girls and their test scores.
