Part II – Analysis and Justification
Construct Development, Scale Creation, and Process Analysis
Many students experience test anxiety which often arises during taking tests and contemplating its consequences. The symptoms consist of specific characteristics that stem from cognitive and physiological functions and have drastic reactive effects (Pekrun, 2001). Test anxiety has a dire impact on students’ ability to progress academically. It also correlates to their complaints of physical and mental issues of illness. With today’s demands and increased mandatory tests for an education, improved constructs, creation of scales, and a processes to analyze and measure test anxiety are a necessity. This will potentially decrease the effects of test anxiety for students who weigh tests too heavily and create concerning academic achievements.
This essay analyzes how this instrument is normalized and its reliability measures, determine the number of participants in the study, and defines their characteristics. In addition, it explains to whom the instrument is generalized, how validity is established and describes the item selection methodology. Lastly, it discusses whether cut-off scores are established and explains how the item selection is evaluated.
Description of Instrument Norm and Reliability Measures Used
“The instrument norm is designed for a group of test takers as a reference for evaluation, interpretation, and context placement of their individual test scores” (Cohen, Swerdlik & Sturman, 2018, I-26). In this study, the norm-referenced test establishes a baseline to examine cognitive functions through methods of score comparisons and performance statistics to measure its influence on test anxiety. For example, data may include poor test preparation, students’ traits of freezing on a test, and heightened self-confidence. Also, if previously established reliability measurements are utilized, it provides a method to compare similar constructs to other tests. A tool for reliability measurement is ‘situation-specific’ which focuses on two main factors of test anxiety; emotional and cognitive measurements (Cohen, Swerdlik ; Sturman, 2018). This would emphasize study habits, skillsets, test perceptions, emotional factors and possibly, cognitive scale measurements for consistency over time (Cohen, Swerdlik ; Sturman, 2018).
Number of Participants
We are working with a small population; therefore, the sample size is larger. This study has 400 students from local elementary, middle school, high school, and one university. For an equal representation, 25 male and 25 female (50) students will be randomly selected from each group and their age; appropriate according to grade level. Collecting the test results would occur during study periods, through study groups and surveys, five days prior to final examinations to gauge the severity of test anxiety.
Respondent Characteristics
In the article Anxious for Success….(n.d.), it viewed test anxiety correlating to the anxiety linked to performance stressors and consisted of cognitive, behavioral, and physiological characteristics. Each sample has its own unique stressors shown in Table 1. (Anxious for Success…, n.d.). Test anxiety characteristics surpass the regular levels of studying students when subjected to stressful circumstances. As a result, as anxiety increases and test performance decreases. The New York State Board found students who exhibit test anxiety often view testing situations as an aversive personal threat. When this occurs, they display high levels of anxiety under testing or evaluating conditions (Anxious for Success…, n.d.).
Respondent Characteristics
Elementary School Restlessness, irritability, aches and pains, temper tantrums, nightmare, nausea
Middle Internalized – worry or withdrawal
Physical symptoms, stomach aches
High School Excessive worry and insomnia, and preoccupied.
Keep worries to themselves
College Fear of failure, threatening situation, thoughts of inadequacy or incapability
Explanation To Whom the Instrument is Generalized
How Validity is Established
Methodology of Item Selection
The methodology of this test is to better understand how often students develop test anxiety while attending academic classes. To measure their frequency, the data from how often students have test anxiety prior to taking tests and the tests results consequences will be used. Additional insight into the frequency of test anxiety will also be obtained by using a random selection of varying age groups. Test reliability and validity of the results are vital to properly score data. Appropriate timing of the test and following testing regulations and procedures will assist with increasing the tests’ success.
Decision to Establish Cut-Off Scores
There will be an established cut-off score when depending on the success of passing the exam or not. Because of the norm test having a baseline it is imperative that all students reach the above baseline for a successful measurement. At the same time comparison of scores will help evaluate the factors associated with poor study habits or test anxiety issues. There has to be a standard (cut-off score) set to have a subjective argument rather the students were successful during the test or not. And if not successful why and how come. The cut-off score will aid in determining just how much of an impact the anxiety driven factors had on the students while testing.
Item Selection Evaluation
The DSM is very detailed about how worrying, irritability, and how the mind can draw blanks. Not only are these symptoms present, but many others. Sweats, inability to focus, and/or restlessness are other common symptoms of anxiety in general. Therefore, once these symptoms are understood a serious of yes or no questions must be asked. A detailed questionnaire can be given before the exam is even administered to help in detecting who may be suffering from a form of anxiety. In this situation, it would be evident that the factor is the exam the students are about to take. These questions would first be administered to those who have clinically been diagnosed with test anxiety. Once they complete the questionnaire then it can be given to the students. The answers are compared, reviewed and considered prior to the exam. This would assist as a preliminary review of how many students experience symptoms of test anxiety.
