Motivating Pre-service Teachers to Incorporate Technology Into the Classroom (open access)

Motivating Pre-service Teachers to Incorporate Technology Into the Classroom

Technology integration into the classroom is a multi-faceted and complex topic. One factor that can have an effect on a teacher's incorporation of technology into their classroom is pre-service teacher technology training. In this research study the ARCS instructional design model was applied to a pre-service teacher technology course in the hopes of motivating course attendees to both learn about technology incorporation and to incorporate technology into their future classrooms. The ARCS instructional design model that relies on the motivational sub-components of attention, relevance, confidences, and satisfaction to develop instruction that motivates to students to learn course content and goals. This study analyzed a group of pre-service teachers enrolled in a university technology training course to determine if the redesign resulted in the desired outcomes. Pre-test and post-test data was collected using both quantitative and qualitative instruments to analyze the potential effect of the redesigned course.

Measuring the Effectiveness of Transfer of Learning Constructs and Intent to Transfer in a Simulation-based Leadership Training Program (open access)

Measuring the Effectiveness of Transfer of Learning Constructs and Intent to Transfer in a Simulation-based Leadership Training Program

The purpose of business training programs is to improve performance, which improved performance changes leadership behaviors based on the knowledge, skills, and abilities (KSAs) learned in training. One of the most common criticisms of leadership training is the tendency to focus on teaching theory but not on applying theory into practice, that is, transfer of learning. Research usually ends at the point of identifying, describing, or measuring factors that influence transfer. Ongoing research must identify what constructs in the transfer of learning process should be effectively changed or managed. There is a gap in research on the degree to which performance improvement through KSAs learned in a simulation training program actually transfer to the work environment. Additional research is needed that examines the relationship between transfer of learning and intent to transfer, which are critical outcomes in the field of human resource management and development. The purpose of the study was to examine the relationship between intent to transfer and four constructs in the transfer of learning process during a simulation-based leadership training program. Participants completed self-report assessments that measured the relationships between intent to transfer and four constructs: ability, motivation, work environment, and learner readiness. A correlational design was …

Preschool Teachers' Self-reported Levels of Preparation for Classroom Behavior Management (open access)

Preschool Teachers' Self-reported Levels of Preparation for Classroom Behavior Management

Research indicates that serious behavior problems begin during the early childhood years. The study examined the perceived preparedness of teachers related to behavior management as well as preschool teachers' usage of evidence-based prevention and intervention strategies. The data indicates that preschool teachers feel prepared for managing aggression in their classrooms and report utilizing evidence-based prevention and intervention strategies regularly. Additionally, the data shows a weak relationship between teacher variables and the likelihood of feeling prepared for managing aggression or utilizing evidence-based strategies. The results can be used to gain a better understanding of special education preschool teachers' training needs in regard to behavior management and managing behavior problems in the preschool classroom.

An Examination of the Similarities and Differences Between Transformational and Authentic Leadership and Their Relationship to Followers' Outcomes (open access)

An Examination of the Similarities and Differences Between Transformational and Authentic Leadership and Their Relationship to Followers' Outcomes

To date there is no comprehensive understanding of what leadership is, nor is there an agreement among different theorists on what a good or effective leader should be. The purpose of this dissertation is to examine the theoretical and empirical similarities and differences of two styles of leadership – transformational and authentic leadership. Follower outcomes, as well as, the effects of trust and psychological capital within these paradigms are of particular interest. Although theoretical differences are proposed for the leadership style, the extent of overlap suggests the need to more closely examine each theory. Pilot studies were created to validate original scenarios created for the study as well as to examine the validity and reliability of new measurement instruments. The dissertation is designed to determine whether the relationships between authentic leadership and a variety of follower outcomes including performance, affective commitment, satisfaction, trust, and organizational citizenship behavior are similar to those between transformational leadership and these outcomes. In addition, variables more unique to authentic leadership research including psychological capital and follower well-being were examined within both paradigms to determine whether their relationships are similar to each type of leadership style. An experimental study using Qualtrics was used to collect the …

Listening to the Freshman Voice: First-year Self-efficacy and College Expectations Based on High School Types (open access)

Listening to the Freshman Voice: First-year Self-efficacy and College Expectations Based on High School Types

This quantitative study used Astin's I-E-O theory to explore the relationship between a college freshman's high school background and academic self-efficacy. The Beginning College Survey of Student Engagement was used to measure academic self-efficacy across four types of high schools. Student gender and precollege experiences (dual-credit and communication assertiveness) were used as control. A total of 15,400 first-year students were included in this study. An ANOVA was used to examine the differences between groups, and ordinary least-square analysis was used to study the factors that affect academic self-efficacy. Results showed statistically significant difference in academic self-efficacy between public and private religious high school graduates. Specifically, graduates of public high schools had statistically higher academic self-efficacy than graduates of private religious high schools (p < .001). Additionally, females and participants of dual-credit courses also tended to have higher academic self-efficacy. Finally, analysis revealed that a first-year student's communication confidence is highly correlated to their academic self-efficacy. Results confirm in-coming first-year students perceive higher education engagement differently based on traits attributed to their precollege experiences. Results point to criteria colleges may be able to use in identifying freshmen at risk for low academic self-efficacy and, therefore, for problems in retention and degree …

Social Exclusion and Green Consumption (open access)

Social Exclusion and Green Consumption

Social exclusion has garnered much attention from researchers across the social sciences, especially among social psychologists. However, given the fact that social relationships and consumption are two of the central activities in daily life, there is surprisingly little research on the impact of social connection threats within the realm of consumer behavior. This study examines the effect of social exclusion on proenvironmental behavior and green consumption. More precisely, the objectives of this study are threefold. The first objective is to examine whether the findings in social psychology literature on how excluded individuals respond to exclusion when they are exposed to proenvironmental consumption behavior. The second objective of this research is to find the underlying mechanism and to rule out some of the possible explanations (e.g., mood) for this effect. The final objective of this study is to establish some of the boundary conditions (individual differences and situational factors) for the proposed effect. The hypotheses of this study were developed based on two main theoretical bases borrowed from social psychology literature: empathy-altruism hypothesis (Batson 1991) and social reconnection hypothesis (Maner et al. 2007). Overall, it was proposed that while social exclusion decreases individuals’ inclination to engage in proenvironmental activities, socially excluded …

Effects of a Brain Improvement Program on Students' Reading Achievement (open access)

Effects of a Brain Improvement Program on Students' Reading Achievement

How to close the reading achievement gap among K-12 students is an ongoing emphasis for educators in the 21st century. The purpose of the study was to determine if using kinesthetic movements from the Brain Gym® program improved the reading achievement of Grade 3 Hispanic and African American students. Students from four elementary schools participated in the study. The students in the control and experimental groups completed a 2004 release TAKS third grade reading assessment for the pretest and posttest. Students in the experimental group completed five selected kinesthetic movements from the Brain Gym® program five minutes at the beginning of each Monday through Friday school day. The intervention lasted 30 days and a total of 150 minutes. Data were analyzed using a 2 x 2 mixed between-within subjects analysis of variance. Findings revealed that performing the five kinesthetic movements from the Brain Gym® program did not increase students' reading achievement scores. Only the variable of time between pretest and posttest affected students' reading scores. The results from this study did not support the findings of other studies of the effectiveness of kinesthetic movements.

Face-to-face Versus Online Gender Roles: the Effect of Psychological Identity on the Characteristics and Circumstances of Online Disinhibition

Human behaviors and social norms are transferred to the Internet in complex and divergent ways. The term online disinhibition has been coined to describe situations when Internet users seem to behave more openly and unrestrained online, often acting in ways they would not dare to act in the face-to-face world. According to Suler, there is a need for future research to "focus on which people, under what circumstances, are more predisposed to the various elements of online disinhibition." With this in mind, this descriptive study sought to determine whether or not people are more true to their authentic psychological identities (i.e., genders) during online interaction or create completely new identities because of the more permissive social norms created by cyberspace. Through video recorded face-to-face discussions, reflective online discussions, open-ended online surveys, and semi-structured interviews, qualitative data was collected for analysis. The results and findings demonstrated that some personality traits are magnified during online interaction, but individuals ultimately stay true to their established gender roles.

A New Era of Educational Assessment: the Use of Stratified Random Sampling in High Stakes Testing (open access)

A New Era of Educational Assessment: the Use of Stratified Random Sampling in High Stakes Testing

Although sampling techniques have been used effectively in education research and practice it is not clear how stratified random sampling techniques apply to high-stakes testing in the current educational environment. The present study focused on representative sampling as a possible means for reducing the quantity of state-administered tests in Texas public education. The purpose of this study was two-fold: (1) to determine if stratified random sampling is a viable option for reducing the number of students participating in Texas state assessments, and (2) to determine which sampling rate provides consistent estimates of the actual test results among the population of students. The study examined students’ scaled scores, percent of students passing, and student growth over a three-year period on state-mandated assessments in reading, mathematics, science, and social studies. Four sampling rates were considered (10%, 15%, 20%, & 25%) when analyzing student performance across demographic variables, including population estimates by socioeconomic status, limited English proficiency, and placement in special education classes. The data set for this study included five school districts and 68,641 students. Factorial ANOVAs were used initially to examine the effects of sampling rate on bias in reading and mathematics scores and bias in percentage of students passing these …

Optimizing Non-pharmaceutical Interventions Using Multi-coaffiliation Networks (open access)

Optimizing Non-pharmaceutical Interventions Using Multi-coaffiliation Networks

Computational modeling is of fundamental significance in mapping possible disease spread, and designing strategies for its mitigation. Conventional contact networks implement the simulation of interactions as random occurrences, presenting public health bodies with a difficult trade off between a realistic model granularity and robust design of intervention strategies. Recently, researchers have been investigating the use of agent-based models (ABMs) to embrace the complexity of real world interactions. At the same time, theoretical approaches provide epidemiologists with general optimization models in which demographics are intrinsically simplified. The emerging study of affiliation networks and co-affiliation networks provide an alternative to such trade off. Co-affiliation networks maintain the realism innate to ABMs while reducing the complexity of contact networks into distinctively smaller k-partite graphs, were each partition represent a dimension of the social model. This dissertation studies the optimization of intervention strategies for infectious diseases, mainly distributed in school systems. First, concepts of synthetic populations and affiliation networks are extended to propose a modified algorithm for the synthetic reconstruction of populations. Second, the definition of multi-coaffiliation networks is presented as the main social model in which risk is quantified and evaluated, thereby obtaining vulnerability indications for each school in the system. Finally, maximization …

Quantifying Forest Vertical Structure to Determine Bird Habitat Quality in the Greenbelt Corridor, Denton, Tx (open access)

Quantifying Forest Vertical Structure to Determine Bird Habitat Quality in the Greenbelt Corridor, Denton, Tx

This study presents the integration of light detection and range (LiDAR) and hyperspectral remote sensing to create a three-dimensional bird habitat map in the Greenbelt Corridor of the Elm Fork of the Trinity River. This map permits to examine the relationship between forest stand structure, landscape heterogeneity, and bird community composition. A biannual bird census was conducted at this site during the breeding seasons of 2009 and 2010. Census data combined with the three-dimensional map suggest that local breeding bird abundance, community structure, and spatial distribution patterns are highly influenced by vertical heterogeneity of vegetation surface. For local breeding birds, vertical heterogeneity of canopy surface within stands, connectivity to adjacent forest patches, largest forest patch index, and habitat (vegetation) types proved to be the most influential factors to determine bird community assemblages. Results also highlight the critical role of secondary forests to increase functional connectivity of forest patches. Overall, three-dimensional habitat descriptions derived from integrated LiDAR and hyperspectral data serve as a powerful bird conservation tool that shows how the distribution of bird species relates to forest composition and structure at various scales.

Evaluating the Cultural Plan of Austin, Texas (open access)

Evaluating the Cultural Plan of Austin, Texas

This is a concurrent, mixed methods study of the impacts of Austin, Texas’s cultural plan, CreateAustin. In the study, trend analysis and a t-test were used to examine variables before and after the cultural plan was in place. At the same time, interviews with cultural planners were used to uncover other effects. My research addresses a gap in the literature between understanding the desired and actual outcomes of a cultural plan. Cultural plans are being developed by many communities in an effort to attract creative workers but they are rarely evaluated. Evaluation using a mixed methods approach is necessary to capture all the outcomes of a cultural plan, rather than the limited scope of impacts that are captured by qualitative or quantitative analyses alone. My analysis of the quantitative variables showed some significant differences between when the plan was in place and the years prior to its creation. Interviews with key stakeholders revealed the formation of new networks as a powerful outcome of the planning process. The results allowed me to gauge the overall impact of CreateAustin and make some observations about the cultural planning process in general, as well as uncover new directions for future research.

Denial of Risk: the Effects of Intentional Minimization on Risk Assessments for Psychopathic and Nonpsychopathic Offenders (open access)

Denial of Risk: the Effects of Intentional Minimization on Risk Assessments for Psychopathic and Nonpsychopathic Offenders

Risk assessments for offenders often combine past records with current clinical findings from observations, interviews, and test data. Conclusions based on these risk assessments are highly consequential, sometimes resulting in increased criminal sentences or prolonged hospitalization. Offenders are therefore motivated to intentionally minimize their risk scores. Intentional minimization is especially likely to occur in offenders with high psychopathic traits because goal-directed deception is reflected in many of the core traits of the disorder, such as manipulativeness, glibness, and superficial charm. However, this connection appears to be based on the conceptual understanding of psychopathy, and it has rarely been examined empirically for either frequency or success. The current study examined the connection between psychopathic traits and the intentional minimization of risk factors using a sentenced jail sample. In general, offenders were able to effectively minimize risk on the HCR-20 and SAQ, while the PICTS, as a measure of cognitive styles, was more resistant to such minimization. Psychopathic traits, especially high interpersonal facet scores, led to greater minimization using a repeated measure, simulation design. Important differences in the willingness and ability to use deception were found based on (a) the content of subscales, and (b) the mode of administration (i.e., interview vs. …

Mental Toughness Training for Police Officers: the Impact of a Stress Inoculation Program on Police Stress

This study examined the impact that a stress inoculation training (SIT) program had on a small-sized city police department in the southwestern U.S. Specifically, the aim of this study was to investigate how a SIT program impacted police officer self-reported levels of organizational stress, operational stress, perceived life stress, and mood states. All 24 participants were recruited from a population of 132 sworn, active duty police officers and were pre-tested through administration of a questionnaire packet containing a host of measures related to demographics, organizational stressors, operational stressors, general life stressors, and mood states. Participants were then randomly assigned to one of the following treatment conditions: (1) delayed training; (2) SIT program; and (3) SIT plus booster program. On completion of the SIT program, members of each of the treatment conditions were re-assessed through the administration of the aforementioned questionnaire packet. Subsequent to conducting the booster sessions, participants from each treatment condition took part in a second, and final, follow-up assessment. Results suggested that organizational stress was decreased for participants in the SIT program, particularly at follow-up. Results also suggested that energy (i.e., vigor) was increased for participants in the SIT plus booster program at both post-test and follow-up. Furthermore, …

Drilling Down Natural Gas Well Permitting Policy:  Examining the Effects of Institutional Arrangements on Citizen Participation and Policy Outcomes (open access)

Drilling Down Natural Gas Well Permitting Policy: Examining the Effects of Institutional Arrangements on Citizen Participation and Policy Outcomes

Over the past decade the movement of natural gas drilling operations toward more suburban and urban communities has created unique policy challenges for municipalities. Municipal response is manifest in a variety of institutional arrangements, some more enabling than others regarding citizen access to public hearings. This observation lead to the main research question, “How are variations in citizen participation affecting policy outcomes?” The argument is made that institutions affecting citizen participation, in turn affect policy outcomes. If the general public is given access to public hearings, their preferences for longer setbacks will be taken into account and the approved gas wells will have greater distances from neighboring residences – effectively providing for greater safety. Given the paucity of research on the topic of natural gas drilling, the research first begins with the presentation of a theoretical framework to allow for analysis of the highly complex topic of gas well permitting, emphasizing the rule-ordered relationships between the various levels of decision making and provides a typology of collective action arenas currently used by Texas municipalities. The research uses paired case studies of most similar design and employs a mixed methods process for the collection, analysis and interpretation of the municipal level …

Indicators of Science, Technology, Engineering, and Math (Stem) Career Interest Among Middle School Students in the Usa

This study examines middle school students' perceptions of a future career in a science, math, engineering, or technology (STEM) career field. Gender, grade, predispositions to STEM contents, and learner dispositions are examined for changing perceptions and development in career-related choice behavior. Student perceptions as measured by validated measurement instruments are analyzed pre and post participation in a STEM intervention energy-monitoring program that was offered in several U.S. middle schools during the 2009-2010, 2010-2011 school years. A multiple linear regression (MLR) model, developed by incorporating predictors identified by an examination of the literature and a hypothesis-generating pilot study for prediction of STEM career interest, is introduced. Theories on the career choice development process from authors such as Ginzberg, Eccles, and Lent are examined as the basis for recognition of career concept development among students. Multiple linear regression statistics, correlation analysis, and analyses of means are used to examine student data from two separate program years. Study research questions focus on predictive ability, RSQ, of MLR models by gender/grade, and significance of model predictors in order to determine the most significant predictors of STEM career interest, and changes in students' perceptions pre and post program participation.

Dynamic Adhesion and Self-cleaning Mechanisms of Gecko Setae and Spatulae (open access)

Dynamic Adhesion and Self-cleaning Mechanisms of Gecko Setae and Spatulae

Geckos can freely climb on walls and ceilings against their body weight at speed of over 1ms-1. Switching between attachment and detachment seem simple and easy for geckos, without considering the surface to be dry or wet, smooth or rough, dirty or clean. In addition, gecko can shed dirt particles during use, keeping the adhesive pads clean. Mimicking this biological system can lead to a new class of dry adhesives for various applications. However, gecko’s unique dry self-cleaning mechanism remains unknown, which impedes the development of self-cleaning dry adhesives. In this dissertation we provide new evidence and self-cleaning mechanism to explain how gecko shed particles and keep its sticky feet clean. First we studied the dynamic enhancement observed between micro-sized particles and substrate under dry and wet conditions. The adhesion force of soft (polystyrene) and hard (SiO2 and Al2O3) micro-particles on soft (polystyrene) and hard (fused silica and sapphire) substrates was measured using an atomic force microscope (AFM) with retraction (z-piezo) speed ranging over 4 orders of magnitude. The adhesion is strongly enhanced by the dynamic effect. When the retraction speeds varies from 0.02 µm/s to 156 µm/s, the adhesion force increases by 10% ~ 50% in dry nitrogen while …

Technology-enhanced Classroom Environments and English Language Acquisition Among Native Spanish-speaking, English Language Learners in the Preschool and Elementary Classroom

This qualitative study addressed the question: What are the perceptions of preschool and elementary bilingual and ESL teachers on how technology-enhanced classroom environments support native Spanish-speaking English language learners in the acquisition of English as a second language? With the support of six school districts representing three different regions and 15 schools in Texas, this research investigated technology-enhanced learning environments and the influence of emerging technologies on language acquisition by focusing on classroom interactions and learner engagement in preschool and elementary settings. Forty-six teachers completed the self-identified online questionnaire and from that initial group of participants, 10 were chosen for the face-to-face semi-structured interviews. A two-cycle progressive refinement coding technique was used for the analysis of the teacher interviews. In Vivo coding was selected for the first-cycle coding methodology to study teacher perspectives using their direct language. For the second-cycle methodology, focus coding was chosen as a continuation of the analytical process examining the developing patterns resulting in the initial codes being grouped to form salient categories. This process of reanalyzing and reorganizing coded data led to the creation of four emergent themes and in the views of the teachers interviewed describes how emerging technologies influences English language acquisition.
