Course Description

 

Measuring psychological characteristics is an important aspect of many professions. This is especially true for professionals in education, psychology and counseling. Data from psychological measures are used to make many decisions. The purpose of this course is to provide a conceptual foundation that will improve your ability to construct, use and make decisions from measures of various psychological constructs. A psychological construct is a mental or psychological characteristic that is inferred from a pattern of behaviors. A few examples of psychological constructs include: academic achievement (knowledge), aptitude, and personality.

 

Course Objectives

 

At the conclusion of this course, students will: 

 

1.     Demonstrate knowledge of the nature of psychological tests and testing.

2.     Demonstrate the ability to analyze and interpret test scores.

3.     Demonstrate knowledge of the concept of reliability.

4.     Demonstrate the ability to apply techniques for estimating the reliability of tests.

5.     Demonstrate the ability to apply estimates of reliability to the interpretation of tests scores.

6.     Demonstrate knowledge of the concept of validity.

7.     Demonstrate knowledge of the methods used to collect evidence of validity.

8.     Demonstrate the ability to apply evidence to the evaluation of the validity of decisions.

9.     Demonstrate knowledge of the advantages and disadvantages of different assessment techniques.

10.  Demonstrate the ability to apply elementary techniques of item analysis.

11.  Demonstrate knowledge of the general characteristics of tests of mental ability.

12.  Demonstrate knowledge of the general characteristics of measures of personality.

13.  Demonstrate knowledge of the issues related to the ethical use of psychological tests.

 


Course Structure

 

Class sessions will typically follow a lecture discussion format; however, when appropriate, I may utilize video or film presentations, demonstrations and group activities. 

 

Readings and Required Text

 

Required Text:          Anastasi, A and Urbina, S. (1997).  Psychological Testing, 7th Edition. Printice Hall, Upper Saddle River, NJ

 

Additionally, relevant and timely articles may be assigned and placed on reserve in the Curriculum Lab.

 

Course Requirements

 

Class attendance and participation are required. If you are absent for any reason I expect that you will communicate that reason to me in a timely fashion. When possible you should notify me in advance of any absence. You are responsible for the material covered on any missed days. Scheduled examinations, missed for appropriate reasons will be made up without penalty. Missed quizzes may not be made up, but will be forgiven if class was missed for an appropriate cause. I reserve the right to consider your attendance and participation patterns when assigning final grades. Participation is defined as relevant and consistent contribution in class discussions.

 

Readings: The assigned readings are to be completed prior to the class period for which they are assigned. Familiarity with the concepts from the readings will facilitate your comprehension of lecture material and enhance your potential for class participation.

 

Assignments: Participation in this course includes participation in three examinations, two mid-terms and a final. All examinations will be cumulative. Preparation and participation in these examinations are an integral part of the learning experience and also serve as a basis for your performance evaluation. 

 

      Mid-term Examinations. There will be two mid-term examinations. Each mid-term exam will comprise of an in-class and take-home portion. The in-class exam will be multiple choice and the take-home portion will be short answer and problems requiring calculation.

 

      Final Examination. There will be a final examination. The final examination will follow the same format as the mid-term examinations.

 


Evaluation Methods

 

Grading:  Grades will be awarded based on the percentage of possible points attained by each student.  In cases where a student's accumulated point total is within 1 point of the cut-off between letter grades, the instructor will use class attendance and participation to make a determination of the final grade.  Students may earn points as follows:

 

Assignment

Points

Date Due/Scheduled

Mid-term Exam 1

100 points

7/19

Mid-term Exam 2

100 points

7/29

Take-home Final

200 points

8/7

Total Possible

400 points

 

 

The final grades will be determined based on a percentage of the total possible points as follows:  A=90% to 100%, B=80%-89%, C=70%-79, D=60%-69, F ¾ 59%. 

 

Course Policies

 

1.   If you are unable to take an examination at the regularly scheduled time, you must contact me in advance to secure my permission.

2.   All written assignments must be typed or word processed. Grades for written assignments will consider: mechanical characteristics (spelling, grammar, etc.), the organization and coherence of ideas and arguments, and the accuracy of content and assertions. No papers will be accepted that are not in the proper format.  Papers are to be double spaced with 1 to 1 inch margins. The exception is calculations which may be neatly hand written.

3.   Written assignments must be submitted on the due date to receive full credit. Late assignments will be penalized 10% for each working day late.

4.   In the event of an unusual final point distribution, the final point requirements may be lowered. This will be solely at my discretion.

5.   Academic dishonesty includes plagiarism, cheating on tests, or lying about work involved in class.  The policies in the NAU Student Handbook apply to such situations.
