Symbolic Design: OXOPretest =o

Treatment = xPosttest = o

A group of 18 third graders in a CTT class will be given the opportunity to participate in a reading program at home with their parents. They will be pretested in school using WRAP

(Writing and Reading Assessment Profile). Then they will be asked to read every night at home with their parents and log the amount of time they read. Parents will have been made

aware of the benefits of reading with their children. After a 6 week period students will receive a posttest using WRAP

(Writing and Reading Assessment Profile) in class.

Reading Levels according to Fountas & Pinnell for the 3rd grade should be between L and P.(exactly one half of the students fall in that range for posttest)

Student Label Interview Question 3 Interview Question 6

A No – my brother No

B No No

C Yes Yes

D Sometimes Yes

E No No

F No- my aunt No

G No No

H Sometimes Yes

I No – my sister Yes

J No No

K Yes Yes

L Sometimes No

M Yes No

N Sometimes No

O Yes No

P No No

Q Yes Yes

R Sometimes Yes

Data- Student Interview QuestionsQuestion 3 – Do you read with one of your parents at night?

Question 6- Do you remember your parents reading to you when you were little?

Rxy =0.13686

There is no correlation between responding yes to reading with a parent at night and a higher reading level.

Information taken from student reading interview. Question # 3 – Do you read with one of your parents at night?

YES – 4 , SOMETIMES – 3, WITH A SIBLING – 2, NO - 1

Reading Level Mode = O Reading Level Range= A - O Likert Scale Mode = 4 (I Strongly Agree) Likert Scale Average= 2.823 Student Interview Mode= Question 3 = NO, With

someone else and sometimes (all had 5), Question 6 = NO

Proposed Descriptive Statistics Parent Survey Mode= Question 1 = yes Reading Level Mode= N Increase in reading level average = 1

*(statistics based on key question from each survey or questionaire)

Letter Levels have been assigned to corresponding numbers.

Rxy =0.102

There is no proposed correlation between parents who responded that they read with their child and improvement in reading levels. (Parent Surveys will be given out after reading logs have been collected.)
