An analysis of the effects of high school student concurrent enrollment at Collin County Community College District.

Access: Use of this item is restricted to the UNT Community
As efforts to provide seamless transitions from high school to college grow, so do the numbers of high school students who concurrently enroll in college courses across the country. The purpose of this study was to evaluate the effectiveness of various aspects of the concurrent enrollment program at Collin County Community College District in Texas. Six research questions were designed to address student success and continuing enrollment patterns after high school graduation, as well as evaluate differences in the various models of dual credit classes offered by the college. Literature related to concurrent enrollment and dual credit programs, senior year of high school, and part-time faculty effectiveness was reviewed. Student issues addressed include: grade performance of concurrent enrollment students compared to the general college population; the percentage of concurrent enrollment students who continue at the college after high school graduation; and a comparison of continuing concurrent enrollment students with a matched sample (based on high school class rank), on the student success factors of fall-to-spring retention rates, fall-to-fall retention rates, grade point averages, and completion rates. Findings were generally positive related to the impact of concurrent enrollment on students and their subsequent success at the college. Various models of offering …

First-Semester General Chemistry Curriculum Comparison of Student Success on ACS Examination Questions Grouped by Topic Following an Atoms First or Traditional Instructional Approach (open access)

First-Semester General Chemistry Curriculum Comparison of Student Success on ACS Examination Questions Grouped by Topic Following an Atoms First or Traditional Instructional Approach

This study uses the ACS first-term general chemistry exam to determine if one curriculum approach is more effective in increasing student success than the other based on their performance on the ACS exam. Two chemistry curriculum approaches were evaluated in this study; the traditional curriculum (TC) and the Atoms First (AF) approach. The sample population was first-semester general chemistry students at Collin College in Frisco, TX. An independent sample t-test was used to determine if there were differences in overall performance between the two curriculum approaches on two different versions of the ACS exam. The results from this study show that AF approach may be a better alternative to the TC approach as they performed statistically significantly better on the 2005 exam version. Factor analysis was used to determine if there were differences between the two curriculum approaches by topic on the ACS exam. Eight different topics were chosen based on topics listed on the ACS Examinations Institute Website. The AF students performed better at a statistically significant level than the TC students on the topics of descriptive chemistry and periodicity, molecular structure, and stoichiometry. Item response theory was used to determine the chemistry content misconceptions held by the students …

The Impact of Target Revenue Funding on Public School Districts in North Texas (open access)

The Impact of Target Revenue Funding on Public School Districts in North Texas

A pre–post case study was conducted to examine how target revenue funding from Texas House Bill 1 (2006) has impacted the school districts within the Texas Education Service Center Region X area. Forced by the courts, the Texas Legislature was required to fix the Texas school finance system because of a de facto statewide property tax it had created by capping school district’s maintenance & operations tax rate at $1.50. Texas Governor Rick Perry used this opportunity to reduce school district M&O taxes by one-third. The Texas Legislature passed House Bill 1 (2006), the Public School Finance and Property Tax Relief Act, in response to the courts and to address a continuous decline in state funding support for public education. The Public School Finance and Property Tax Relief Act reduced local school districts’ property tax rates and revenue with the assurance that these funds would be exchanged for state aid. Local school property taxes were reduced over two years, 2006–2007 and 2007-2008, by 33%. In order for the State of Texas to meet the state aid funding guarantee from House Bill 1 (2006), each school district was frozen to its 2005–2006 revenue per weighted student, which was called a district’s …

Residential Grid-Connected Photovoltaics Adoption in North Central Texas: Lessons from the Solarize Plano Project (open access)

Residential Grid-Connected Photovoltaics Adoption in North Central Texas: Lessons from the Solarize Plano Project

Residential Grid-Connected Photovoltaics (GPV) systems hold remarkable promise in their potential to reduce energy use, air pollution, greenhouse gas emissions, and energy costs to consumers, while also providing grid efficiency and demand-side management benefits to utilities. Broader adoption of customer-sited GPV also has the potential to transform the traditional model of electricity generation and delivery. Interest and activity has grown in recent years to promote GPV in north central Texas. This study employs a mixed methods design to better understand the status of residential GPV adoption in the DFW area, and those factors influencing a homeowner's decision of whether or not to install a system. Basic metrics are summarized, including installation numbers, distribution and socio-demographic information for the case study city of Plano, the DFW region, Texas, and the United States. Qualitative interview methods are used to gain an in-depth understanding of the factors influencing adoption for the Solarize Plano case study participants; to evaluate the effectiveness of the Solarize Plano program; and to identify concepts that may be regionally relevant. Recommendations are presented for additional research that may advance GPV adoption in north central Texas.

Assessing the Efficacy of Learning Communities at Four North Texas Community Colleges. (open access)

Assessing the Efficacy of Learning Communities at Four North Texas Community Colleges.

This observational study involving intact groups and convenient sampling examined learning communities at four North Texas Community Colleges. The purpose of this study was to determine if there was a significant difference in cathectic learning climate, inimical ambiance, academic rigor, affiliation and structure among students in learning communities and freestanding classes. Learning communities are gaining nationwide popularity as instruments of reform in Higher Education. Recent studies have discussed the benefits of learning communities to student, faculty and institutions. As learning communities are gaining popularity, especially at the community college level, there is a need to determine if the learning communities are significantly different than freestanding classes. The College Classroom Environment Scales, developed by Winston, Vahala, Nichols, Gillis, Wintrow, and Rome (1989), was used as the survey instrument for this study. Using SPSS 10.1, a multivariate analysis of variance, (Hotelling's T2) was performed on five dependent variables: cathectic learning climate (CLC), inimical ambiance (IA), academic rigor (AR), affiliation (AF), and structure (ST), which yielded a significant difference. The independent variable was learning community compared to freestanding classes (group). Follow-up independent t tests were also conducted to evaluate the differences in the means between the two groups and to explore which dependent …

Ozone Pollution Monitoring and Population Vulnerability in Dallas-Ft. Worth: A Decision Support Approach

In urban environments, ozone air pollution, poses significant risks to respiratory health. Fixed site monitoring is the primary method of measuring ozone concentrations for health advisories and pollutant reduction, but the spatial scale may not reflect the current population distribution or its future growth. Moreover, formal methods for the placement of ozone monitoring sites within populations potentially omit important spatial criteria, producing monitoring locations that could unintentionally underestimate the exposure burden. Although air pollution affects all people, the combination of underlying health, socioeconomic and demographic factors exacerbate the impact for socially vulnerable population groups. A need exists for assessing the spatial representativeness and data gaps of existing pollution sensor networks and to evaluate future placement strategies of additional sensors. This research also seeks to understand how air pollution monitor placement strategies may neglect social vulnerabilities and therefore, potentially underestimate exposure burdens in vulnerable populations.

An Exploratory Study of Factors Influencing the Effectiveness of the Amob/vll Program for Participants in North Central Texas (open access)

An Exploratory Study of Factors Influencing the Effectiveness of the Amob/vll Program for Participants in North Central Texas

This study assessed falls efficacy and confidence-related changes among participants attending the a Matters of Balance/Volunteer Lay Leader (AMOB/VLL) falls prevention program for older adults, based on their residential location. Data were examined from 431 older Texans enrolled in AMOB/VLL during a two-year period, and assessed at baseline and post-intervention. Results indicate that participants significantly increased falls efficacy, reduced activity interference due to their health, and decreased the number of days limited from usual activity. Regression models show that participants, despite entering the program with lower reported health status, reported greater rates of positive change for falls efficacy and health interference compared with their baseline pre-intervention counterparts. Overall program attendance and attendance at major sessions showed the greatest influence. Findings contribute to the understanding of cognitive restructuring and strengthening variations with falls prevention program outcomes.

Student to Teacher Racial/Ethnic Ratios as Contributors to Regional Achievement Gaps, 1999-2008 (open access)

Student to Teacher Racial/Ethnic Ratios as Contributors to Regional Achievement Gaps, 1999-2008

With the advent of No Child Left Behind legislation in 2002 and its mandates for annual yearly progress for all students, many districts and schools in Texas have had difficulty elevating African American and Hispanic students’ scores. The current study examined these students’ achievement on the annual Texas high-stakes measure as a function of a numerical construct that aligns the race/ethnicity of students when the teacher race is White. Earlier studies have shown that racial/ethnic compatibility between students and teachers improves student achievement in the primary grades. The study, which was set in 10 north Texas school districts and 30 high schools, middle schools, and elementary schools, examined African American and Hispanic students’ achievement on the Texas state assessments in reading and mathematics over a 10-year period. District performance data came from 4,664,192 African American, Hispanic, and White students and 222, 834 White teachers. Campus level data encompassed 188,839 10th graders, 93,573 eighth graders, and 40,083 fourth graders, and 20,471 White teachers. Analysis revealed that, as the ratios of African American and Hispanic students to White teachers increased, the percentages of these two student groups passing the Texas assessments decreased. These patterns differed for White students whose passing percentages increased …

Suburban Succession and Stream Dynamics

Increasingly higher numbers of people are moving into urbanizing environments, yet our understanding of ecosystem consequences of rapid urbanization is still in its infancy. In this dissertation, I assessed dynamics of residential landscapes during suburban succession and consequences for ecosystem functioning. First, I used a space-for-time approach to quantify more than a century of suburban succession in the Dallas – Fort Worth metroplex (DFW). Attributes of residential landscape plant diversity and habitat complexity were quantified for 232 individual properties nested within 14 neighborhoods constructed between 1906 and 2020. Suburban succession progressed from simple turf lawns with limited habitat complexity to landscapes dominated by deciduous trees and high habitat complexity, but homeowner decisions related to landscape management affect the rate of that transition and the number of plants and taxa present. Next, I used the novel spatial construct of "neighborhoodsheds" to test for effects of suburban succession on carbon export, and found that the proportion of carbon derived from C3 vs. C4 plants was affected by neighborhood plant community structure (i.e. greater proportion of trees and shrubs primarily in later stages of suburban succession). Finally, I conducted a mesocosm experiment to test effects of changes in allochthonous inputs during suburban succession …

A Follow-Up Study of the Subsequent Educational Placement and Categorical Classification of Preschool Early Childhood Special Education Students in Selected Rural and Urban Settings (open access)

A Follow-Up Study of the Subsequent Educational Placement and Categorical Classification of Preschool Early Childhood Special Education Students in Selected Rural and Urban Settings

Proponents of special education early childhood interventions programs have promoted the assumptions that these programs: (a) will have a positive effect on the long-term outcomes of preschool children with disabilities; (b) will result in some children no longer requiring special education services throughout their elementary school years; and (c) will facilitate the need for fewer services for those students who do remain in special education programs throughout their education. The purpose of this follow-up study is to identify and describe the placement decisions and the changes of exceptionality classification for children identified as special education early childhood students over the course of six follow-up years. This study (a) identifies 108 children from rural and urban school settings who were enrolled in Early Childhood Special Education (ECSE) programs in 1990-91, (b) documents their categorical label and educational placement six years later, and (c) then determines the differences in the number of hours rural and urban students receive special education and/or related services in 1996-97.

Evolution and Devolution of Inpatient Psychiatric Services: From Asylums to Marketing Madness and Their Impact on Adults and Older Adults with Severe Mental Illness

I examined the factors that led to the rise and fall of psychiatric hospitals and its impact on two select groups of individuals: adults and older adults with severe mental illness. To explore the reasons behind these fluctuations, the State of Texas was used as a case study. Additionally, the fluctuations occurred for different reasons in public vs. for-profit investor-owned psychiatric hospitals. Using an investor-owned psychiatric hospital organization as a case study, I investigated the differences in factors that influenced the growth and/or demise in public vs. investor-owned psychiatric hospitals. Evolution and devolution of psychiatric hospitals was assessed during select time periods: 1700 to1930, 1940 to1970, 1980 to 2000, and 2000 to present. Time period selections were relevant to the important drivers of the span of time that influenced the psychiatric hospitals. Historical review and trend analysis was used to identify the total number of psychiatric hospitals and/or total number of psychiatric hospital beds and psychiatric hospitals by type. Analysis showed there was a cyclical pattern of evolution and devolution of psychiatric hospitals and each cycle altered the form, function, and role of the psychiatric hospital along with altering the location of care for adults and older adults with severe …

Effects of Board Training on the Relationship Between Board Members and CEOs (open access)

Effects of Board Training on the Relationship Between Board Members and CEOs

The purpose of this study is to ascertain the opinions of chief executive officers (CEOs) and school board chairs of Texas private schools in educational service center (ESC) Regions 10 and 11 toward board training and the potential benefits for the success of their respective roles. Literature regarding private school board training is limited. As a result, most private school boards face challenges regarding school board training expectations, which could affect their roles and the roles of CEOs. The quantitative and qualitative cross-sectional research design examined Texas private school CEOs’ and school board chairs’ perceptions about school board training and the working relationships between Texas school CEOs and school boards. The researcher developed the survey and interview questions used in this study. Responses to a 4-point Likert-type scale instrument, short answer questions, and interviews were solicited from a population of private school CEO and school board chairs within ESC Regions 10 and 11 from schools with an enrollment of at least 100 students and that contained Grades 9 through 12. In-depth Interviews were conducted with 12 private school CEOs and 12 school board chairs with varying levels of school board training. The research findings indicate that board training does make …

The Relationship Among Effective School Correlates, School and District Practices, and Exemplary Student Performance in Texas (open access)

The Relationship Among Effective School Correlates, School and District Practices, and Exemplary Student Performance in Texas

The Texas Education Agency (TEA) annually rates campuses and districts on how well they meet standards of student performance. Since the high standard is so difficult for campuses and districts to reach, educators continually seek ways to improve student performance. The effective schools process is research-based and has stood the test of time. Descriptive statistics were used in this study to identify practices within the effective schools correlates that exemplary campuses implement. Campuses with long-term exemplary ratings were identified using the TEA data base. Campus site-based teams were surveyed using the More Effective Schools Staff Survey. Data was collected on elementary and secondary campuses with homogenous, diverse, economically advantaged, and economically disadvantaged student populations. District instructional leaders for those campuses completed a District Instructional Leader Survey to determine what practices districts implement to support their exemplary campuses. Findings from this quantitative study revealed what effective schools practices were highly evident on these exemplary campuses, regardless of diversity, economic status, district size, community type, property wealth, or location within the state. Findings also revealed that district leaders provide direction and support in the areas of (a) professional development; (b) beliefs, mission, and goals; (c) curriculum; (d) instruction; (e) assessment; and (f) …

A Descriptive History of Wesley College (open access)

A Descriptive History of Wesley College

The American junior colleges of today are historical accidents, some having begun originally with elementary and secondary divisions or as adjuncts of local high schools. Wesley College in Greenville, Texas, began on a two acre campus as North Texas University Training School in Terrell, Texas, in 1905. Chartered by the North Texas Conference of the Methodist Episcopal Church, South, the school initially provided elementary and high school and two years of college. At this time the name was changed to Wesley College, but the school closed in the spring of 1911. It reopened on a twenty acre campus in the fall of 1912 in Greenville, Texas, and maintained a close relationship with that city until mounting financial problems forced closure in 1938. Many records of the school were transferred to Southern Methodist University at Dallas, and in 1939, Wesley College alumni were invited to become associate members of the S.M.U. Ex-Students Association. Many associated with Wesley College continue to meet annually in Greenville to keep alive their memories of the once prestigious college. This study employs primary and secondary documentary data, as well as interviews with fifty-six individuals, to provide a chronological descriptive history of the origin, growth, development, and …
