  1. The Effects of Single-Parent Families on Student Academic Achievement Christina Michalek ED 703.22 Spring 2009

  2. Table of Contents • Research Design • Threats to Internal Validity • Threats to External Validity • Proposed Data • Correlational Graph • References

  3. Research Design • Pre-Experimental • Quasi-Experimental • One designated treatment group (X1) • Sample was not randomly selected

  4. Threats to Internal Validity • History • Participants may not be fully focused on completing the instruments of the study • Participants may not be completely honest when answering surveys and questionnaires • Changes in surroundings – fire drills, phone ringing, announcements being made, someone entering the room • Experimental Morality • Participants may choose to no longer be part of the study • Students may move to a new school • Selection-Maturation Interaction • Students may become bored when answering surveys and questionnaires • Students may not pay attention to what is being asked of them • Instrumentation • Parents may refuse to complete questionnaires and surveys at any point

  5. Threats to External Validity • Experimental Procedures • Students and parents may answer questions based on what they feel is the “best answer.” At times, this is not always the truth • Selection Treatment Interaction • Participants were not chosen at random. It is a set sample. • Treatment Diffusion • Students and parents may talk amongst themselves about the contents of assessments, questionnaires, and surveys. • Reactive Agreements/Participants Effects • Attitudes of participants may change over time. • For example, a student may be having a bad day. This will affect the student’s answers to surveys and questionnaires. It may also affect the assessment data of the survey.

  6. Proposed Data-Survey Question • Student Survey Questions How often do your parents/guardians do the following? 1) Never 2) Hardly Ever 3) Sometimes 4) Always -Help you with your homework _____ -Talk to you about how you can improve in your schoolwork _____ -Make sure you do your homework assignments _____ -Talk to your teachers about how you are doing in school _____ -Go to school activities and meetings _____ _______________________________________________________________________________ 1) 0-30 minutes 2) 30 minutes to 1 hour 3) 1 hour-1 ½ hours 4) more than 2 hours -How long does it take you to complete your homework? _____ -How long do your parents help you with your homework? _____ -How long do you study before a test? _____ -How long do you spend reading each night? _____ -How long do you speak to your parents about your school day? _____

  7. Homework Help Proposed Question: How long do you spend helping your child with homework? (1) 0-30 minutes (2) 30 minutes-1 hour (3) 1 hour-1 ½ hours (4) More than 2 hours

  8. Assessment Results

  9. Correlational coefficient : (rxy) 0.890439789 • This shows that there is a good correlation between test averages of students who have one parent and students who have two parents.

  10. Attitude Towards School

  11. Correlational coeffiecient: (rxy) -0.904534034 • This shows that there is no correlation of attitudes towards school between students with one parent or two parents.
