How Utah Parents Of Utah School Children Judge School Effectiveness, Philip L. Rodgers May 2003

How Utah Parents Of Utah School Children Judge School Effectiveness, Philip L. Rodgers

All Graduate Theses and Dissertations

There is a perceived crisis concerning public education in the United States. This has led to an increase in the use of standardized tests for the purpose of measuring school effectiveness. However, the use of standardized tests for this purpose is problematic. Among these problems is the concern that standardized tests may not measure what parents believe are the most important attributes of an effective school. Unfortunately, there is little in the way of empirical evidence regarding parent beliefs in this area.

The purpose of this research was to answer the following four questions.

1. What do parents of school-aged ...


Accuracy Of Discrimination, Rate Of Responding, And Resistance To Change, John A. Nevin, Jessica S. Milo, Amy Laurie Odum, Timothy A. Shahan Jan 2003

Accuracy Of Discrimination, Rate Of Responding, And Resistance To Change, John A. Nevin, Jessica S. Milo, Amy Laurie Odum, Timothy A. Shahan

Timothy A. Shahan

Pigeons were trained on multiple schedules in which responding on a center key produced matching-to-sample trials according to the same variable-interval 30-s schedules in both components. Matching trials consisted of a vertical or tilted line sample on the center key followed by vertical and tilted comparisons on the side keys. Correct responses to comparison stimuli were reinforced with probability .80 in the rich component and .20 in the lean component. Baseline response rates and matching accuracies generally were higher in the rich component, consistent with previous research. When performance was disrupted by prefeeding, response-independent food during intercomponent intervals, intrusion of ...

Psychology Faculty Publications

A population-based prevalence sample of 355 residents of Cache County, Utah, who were diagnosed with dementia, was rated on the Neuropsychiatric Inventory (NPI). Of the 355 residents, 119 had no neuropsychiatric symptoms at baseline and were, consequently, at risk for incident mental and behavioral disturbances. The NPI was readministered approximately 18 months later to 61 surviving participants. Sixty-nine percent developed at least one mental or behavioral symptom. Delusions were most common (28%), followed by apathy (21%), and aberrant motor behavior (21%). When this incidence rate of 69% was combined with a previously estimated prevalence rate of 61%, the cumulative 18-month ...


An Evaluative Argument-Based Investigation Of Validity Evidence For The Utah Pre-Algebra Criterion-Referenced Test, Louise Richards Moulding May 2001

An Evaluative Argument-Based Investigation Of Validity Evidence For The Utah Pre-Algebra Criterion-Referenced Test, Louise Richards Moulding

All Graduate Theses and Dissertations

This study collected evidence to address the assumptions underlying the use of the Utah Core Assessment to Pre-Algebra (UCAP) to (a) measure student achievement in pre-algebra, and (b) assist teachers in making adjustments to instruction. An evaluative argument was defined to guide the collection of evidence. Each of the assumptions in the evaluative argument was addressed using data from a suburban northern Utah school district. To collect the evidence, test content was examined including item match to course objectives, reliability, and subtest intercorrelations. Analyses of correlations of the UCAP with convergent and discriminant measures were completed using student test data ...

The Use Of Defensiveness As A Covariate Of Self-Report In The Assessment Of Self- Concept Among Navajo Adolescents, Bruce Leon Arneklev May 1970

The Use Of Defensiveness As A Covariate Of Self-Report In The Assessment Of Self- Concept Among Navajo Adolescents, Bruce Leon Arneklev

All Graduate Theses and Dissertations

The study investigated the relationship between defensiveness scores and self- report scores as they interrelate in the assessment of self - concept and its change. Data were analyzed to determine if self- report scores adjusted by regression for defensiveness would be more congruent with a criterion measure than unadjusted scores.

A secondary problem was to evaluate the extent to which the self criticism scale on the Tennessee Self Concept Scale (TSCS) and the self report vs. objective rating discrepancy method would identify the same individuals as defensive.

Samples were drawn from a population of adolescent Navajo boarding school students. A treatment ...
