create a dataset that can be used for calculating descriptive statistics and making graphs.

If you have access to SPSS (Statistical Package for the Social Sciences), create a dataset that can be used for calculating descriptive statistics and making graphs. When you open SPSS, the title of the page will be Untitled SPSS Data Editor. The tab at the bottom (Data View) tells you that you are in the right screen to enter your data. The variables are named across the top, and each number on the left corresponds to a different subject. Once you have entered the scores, it is best to open the tab named Variable View and specify characteristics of each variable. Click on Analyze to see a number of different procedures. Select Descriptive Statistics and then Descriptives and Explore. To do the correlation, click on Correlate and then….

identify the type of evidence presented for validity

For each of the following descriptions, identify the type of evidence presented for validity:

a. Mr. Jones contends that his measure of athletic prowess is consistent with student self-reports.

b. In this study, the investigator took deliberate steps to make sure that the test contained the right concepts. She asked several colleagues to review the items to see if, in their opinion, the right concepts were included.

c. In a study of college student values, a researcher decided to correlate the measure of values with observations of values by residence hall assistants. The selfreport results matched the observations.

d. Dr. Lewis, a professor of education, is working on an instrument that can be used to predict which of his students will be effective teachers. He has several scores….

identify the type of evidence for reliability.

For each of these descriptions, identify the type of evidence for reliability.

a. Mr. Fox is the principal of Herring Middle School. He is working on a measure of teacher job satisfaction and has developed a number of items for different traits. He hopes that about six items per trait will be sufficient.

b. A college counselor is interested in knowing whether small-group counseling with students having difficulties have made a difference. She has developed a measure of self-confidence and anxiety for her study and has given this measure to a control group of students four times during the semester.

c. Kevin Sutherland is a professor of special education. He does single-subject research and needs to use several different graduate students to collect data. He gathers pilot data….

Identify each of the following examples as either formative or summative evaluation.

Identify each of the following examples as either formative or summative evaluation.

a. Tests were administered to see how much teachers’

knowledge of mathematics improved.

b. The goal of the evaluation of the new drama education

series was to see if students’ attitudes toward drama had

changed.

c. Project directors received regular communications

from the evaluator throughout the implementation of

a new curriculum.

d. A new way of advising students was established in a

school of education. Student data were obtained to conduct an evaluation of the effectiveness of the new system.

e. A new evaluation design was implemented that

included both internal and external evaluators.

f. The data showed project directors how to improve the

delivery of a new method of student learning.

Classify each of the following descriptions as objectivesoriented, decision-oriented, or participant-oriented.

Classify each of the following descriptions as objectivesoriented, decision-oriented, or participant-oriented.

a. Mr. Green, principal of Midlothian High School, used

a multimethod approach to the selection of a new book

series for English instruction. He gathered students’

perceptions from a pilot test and teacher ratings and

also looked into the companies providing the different

book series.

b. Professional development of teachers to improve their

assessment of student learning was implemented at

James River High School. The results showed that 80

percent of the participating teachers had adopted new

procedures that were emphasized in the training.

c. Dr. Abrams recently conducted an evaluation of a new

doctoral program. The evaluation consisted of obtaining multiple perspectives about the program, including

those of faculty and students. She also observed faculty

discussions….

Indicate whether each of the following is an example of action research.

. Indicate whether each of the following is an example of

action research.

a. A researcher is interested in examining the correlation

between high-stakes testing and grades. The test scores

and grades are from 2000–2003.

b. A teacher is interested in studying the effects of smallgroup counseling on her students’ self-esteem. Thirty

students participate as subjects. The Coopersmith SelfEsteem Inventory is given as a pretest and a posttest,

and interviews are used to follow up with students every

month.

c. Service learning is becoming very popular in both public schools and colleges and universities. However, relatively little is known about the perceptions of the

beneficiaries of the services. A study is prepared to

examine these perceptions using focus group interviews

and a questionnaire to ask participants about the….

What should the teacher do to ensure credible results?

1. In your own field of work and study, suggest an action research study that uses a mixed method design.

2. Suppose a teacher decides to study the impact of technology on the attention behavior of her fifth-grade students.

She makes observations of students for three weeks before

the technology is introduced and then continues her

observations for the next three weeks while students use

the technology. The results suggest that students pay

increased attention when they use technology, so the

teacher decides to use it for the rest of the semester.

a. What should the teacher do to ensure credible results?

b. How can teacher bias be controlled?

c. Is this an example of cyclical research? Why or why

not?

Which qualitative strategies would be appropriate?

The director of an inner-city preschool program wants

to obtain parents’ perspectives of the program. She is

especially interested in this year’s innovation in one

class: a parent education program. Materials are sent

home twice a week for a parent or guardian to work with

the child, and records of teacher-parent contacts are

made. There are 12 children in the preschool class. Four

children live with a single parent, six live with both parents, and two children live with one parent and their

grandparents.

a. What type of sampling is appropriate and why? (probability or qualitative)

b. How should the sampling be done?

c. Which qualitative strategies would be appropriate?

Which type of sampling is appropriate and why? (probability or qualitative)

A researcher wants to understand the concept of sitebased school management. He has located a school district

that has spent one year in planning and writing guidelines

for site-based management at six selected schools. The

researcher is primarily interested in how a site-based management team operates and whether this affects the role

of the principal and the school’s relationship to the district’s central management. A site-based management

team consists of six members from the community and

three teachers plus the principal as an ad hoc member. A

central office facilitator frequently attends the monthly

meetings after conducting six orientation sessions. How

would you design the study?
