Alternative Certification: A Comparison of Factors Affecting the Motivations of General and Special Educators

Alternative Certification: A Comparison of Factors Affecting the Motivations of General and Special Educators

Date: August 2010
Creator: Hogan, Kathleen Ann
Description: This study was developed to examine the motivations of individuals who chose alternative routes to teacher certification and what they believe were the strengths and weaknesses of their alternative certification preparation (ACP). Data accrued from this study were based on a 55-item online survey and participant information from an online focus group. The study compared the differences between general and special educators in regards to the motivating factors affecting the decision to become a teacher, remain a teacher, and in choosing a non-university-based ACP, as well as the perceived strengths and weaknesses of the ACP. The results from the survey suggest there are differences in the motivating factors affecting general and special educator's decision to become a teacher and to remain a teacher. Additional survey results suggest there are no differences in the reason these two groups chose a non-university-based ACP. The results of the survey and the online focus group were comparable for these two groups. The remainder of this dissertation includes a review of literature related to teacher shortages and teacher preparation including alternative certification. Additionally, information on the results and analysis of the study are discussed, as well as recommendations for future research.

Attenuation of the Squared Canonical Correlation Coefficient Under Varying Estimates of Score Reliability

Attenuation of the Squared Canonical Correlation Coefficient Under Varying Estimates of Score Reliability

Date: August 2010
Creator: Wilson, Celia M.
Description: Research pertaining to the distortion of the squared canonical correlation coefficient has traditionally been limited to the effects of sampling error and associated correction formulas. The purpose of this study was to compare the degree of attenuation of the squared canonical correlation coefficient under varying conditions of score reliability. Monte Carlo simulation methodology was used to fulfill the purpose of this study. Initially, data populations with various manipulated conditions were generated (N = 100,000). Subsequently, 500 random samples were drawn with replacement from each population, and data was subjected to canonical correlation analyses. The canonical correlation results were then analyzed using descriptive statistics and an ANOVA design to determine under which condition(s) the squared canonical correlation coefficient was most attenuated when compared to population Rc2 values. This information was analyzed and used to determine what effect, if any, the different conditions considered in this study had on Rc2. The results from this Monte Carlo investigation clearly illustrated the importance of score reliability when interpreting study results. As evidenced by the outcomes presented, the more measurement error (lower reliability) present in the variables included in an analysis, the more attenuation experienced by the effect size(s) produced in the analysis, in this ...

Comparing the Effects of Home Versus Clinic-Based Parent Training for Children with Autism

Comparing the Effects of Home Versus Clinic-Based Parent Training for Children with Autism

Date: May 2010
Creator: Crone, Regina M.
Description: Research with parents on managing child problem behavior typically measures either child or parent behavior. This study was designed to evaluate the effectiveness of training parents to implement a function-based behavior intervention plan (BIP) in a non-trained natural environment utilizing a Multiple Probe Design across Participants. Participants included four parent-child dyads. Measurement variables included parents' use of effective and ineffective strategies and child problem behavior. Intervention involved training parents to understand and implement the BIP using effective strategies, modeling the effective procedures, and providing feedback following parent implementation of procedures. Results showed that the intervention was very effective in promoting skill generalization of parents and decreasing child problem behavior. The findings have implications for research and clinical practice.

Comparing Three Effect Sizes for Latent Class Analysis

Comparing Three Effect Sizes for Latent Class Analysis

Date: December 2015
Creator: Granado, Elvalicia A.
Description: Traditional latent class analysis (LCA) considers entropy R2 as the only measure of effect size. However, entropy may not always be reliable, a low boundary is not agreed upon, and good separation is limited to values of greater than .80. As applications of LCA grow in popularity, it is imperative to use additional sources to quantify LCA classification accuracy. Greater classification accuracy helps to ensure that the profile of the latent classes reflect the profile of the true underlying subgroups. This Monte Carlo study compared the quantification of classification accuracy and confidence intervals of three effect sizes, entropy R2, I-index, and Cohen’s d. Study conditions included total sample size, number of dichotomous indicators, latent class membership probabilities (γ), conditional item-response probabilities (ρ), variance ratio, sample size ratio, and distribution types for a 2-class model. Overall, entropy R2 and I-index showed the best accuracy and standard error, along with the smallest confidence interval widths. Results showed that I-index only performed well for a few cases.

Computer Assisted Instruction to Improve Theory of Mind in Children with Autism

Computer Assisted Instruction to Improve Theory of Mind in Children with Autism

Date: December 2014
Creator: Eason, Lindsey R.
Description: Children with autism spectrum disorder (ASD) show significant deficits in communication, emotion recognition, perspective taking, and social skills. One intervention gaining increased attention is the use of computer assisted instruction (CAI) to teach social, emotional and perspective-taking skills to individuals with ASD with the purpose of improving theory of mind skills. This study evaluated the effectiveness of CAI for improving theory of mind skills in four children with high functioning autism ages 5 to 12 years. A single-subject multiple baseline research design across participants was utilized to evaluate the effectiveness of CAI. The software contained 22 instructional scenarios that asked participants to identify emotions of characters based on situational cues displayed in line drawn pictures and audio feedback for correct and incorrect responses. Mind-reading skills were assessed using ten randomly selected scenarios for various emotions and no audio feedback. Visual analysis of the data revealed that all four participants increased mind-reading skills during the CAI condition. Additionally, this study evaluated levels of task engagement during experimental conditions. Three of the four participants showed an increase in task engagement during CAI compared to paper-based social stories used during baseline. Generalization of skills was assessed through the use of social scenarios acted ...

Construct Validation of the Social-Emotional Character Development Scale in Belize: Measurement Invariance Through Exploratory Structural Equation Modeling

Construct Validation of the Social-Emotional Character Development Scale in Belize: Measurement Invariance Through Exploratory Structural Equation Modeling

Date: August 2014
Creator: Hinerman, Krystal M.
Description: Social-emotional learning (SEL) measures assessing social-emotional learning and character development across a broad array of constructs have been developed but lack construct validity. Determining the efficacy of educational interventions requires structurally valid measures which are generalizable across settings, gender, and time. Utilizing recent factor analytic methods, the present study extends validity literature for SEL measures by investigating the structural validity and generalizability of the Social-Emotional and Character Development Scale (SECDS) with a large sample of children from schools in Belize (n = 1877, ages 8 to13). The SECDS exhibited structural and generalizability evidence of construct validity when examined under exploratory structural equation modeling (ESEM). While a higher order confirmatory factor structure with six secondary factors provided acceptable fit, the ESEM six-factor structure provided both substantive and methodological advantages. The ESEM structural model situates the SECDS into the larger body of SEL literature while also exhibiting generalizability evidence over both gender and time.

Convergent Validity of Variables Residualized By a Single Covariate: the Role of Correlated Error in Populations and Samples

Convergent Validity of Variables Residualized By a Single Covariate: the Role of Correlated Error in Populations and Samples

Date: May 2013
Creator: Nimon, Kim
Description: This study examined the bias and precision of four residualized variable validity estimates (C0, C1, C2, C3) across a number of study conditions. Validity estimates that considered measurement error, correlations among error scores, and correlations between error scores and true scores (C3) performed the best, yielding no estimates that were practically significantly different than their respective population parameters, across study conditions. Validity estimates that considered measurement error and correlations among error scores (C2) did a good job in yielding unbiased, valid, and precise results. Only in a select number of study conditions were C2 estimates unable to be computed or produced results that had sufficient variance to affect interpretation of results. Validity estimates based on observed scores (C0) fared well in producing valid, precise, and unbiased results. Validity estimates based on observed scores that were only corrected for measurement error (C1) performed the worst. Not only did they not reliably produce estimates even when the level of modeled correlated error was low, C1 produced values higher than the theoretical limit of 1.0 across a number of study conditions. Estimates based on C1 also produced the greatest number of conditions that were practically significantly different than their population parameters.

Criterion Validity of Common Career Interest Inventories: Relative Efficacy with High School Seniors.

Criterion Validity of Common Career Interest Inventories: Relative Efficacy with High School Seniors.

Date: August 2014
Creator: Martin, Summer M.G.
Description: Professional school counselors frequently use career interest inventories as part of a comprehensive guidance program to help students create a post-secondary school plan. The present study evaluates the validity of three commonly used interest inventories, the Myers-Briggs Type Indicator, Self-Directed Search, and Strong Interest Inventory on field of study choice for graduating high school seniors (N = 616) from a large, suburban high school in Texas. Students identified their intended postsecondary field of study category, were randomly assigned using stratification to three groups, and each group completed a different inventory. Group membership was evaluated to establish covariate balance on a wide variety of indicators. Data from each group was evaluated to determine the extent to which the inventory predicted the chosen field of study, as well as Other and Undeclared categories using logistic regression models. None of the inventory models suggest that the inventory accurately predicts Other or Undeclared outcomes. For students selecting intended postsecondary fields of study, the Self Directed Search predicts such outcomes better than other measures. Professional school and career counselors should consider the SDS in addition to narrative counseling strategies to add greater precision with career decision making among clients and students.

Determination of the Optimal Number of Strata for Bias Reduction in Propensity Score Matching.

Determination of the Optimal Number of Strata for Bias Reduction in Propensity Score Matching.

Date: May 2010
Creator: Akers, Allen
Description: Previous research implementing stratification on the propensity score has generally relied on using five strata, based on prior theoretical groundwork and minimal empirical evidence as to the suitability of quintiles to adequately reduce bias in all cases and across all sample sizes. This study investigates bias reduction across varying number of strata and sample sizes via a large-scale simulation to determine the adequacy of quintiles for bias reduction under all conditions. Sample sizes ranged from 100 to 50,000 and strata from 3 to 20. Both the percentage of bias reduction and the standardized selection bias were examined. The results show that while the particular covariates in the simulation met certain criteria with five strata that greater bias reduction could be achieved by increasing the number of strata, especially with larger sample sizes. Simulation code written in R is included.

Eastern Work Ethic: Structural Validity, Measurement Invariance, and Generational Differences

Eastern Work Ethic: Structural Validity, Measurement Invariance, and Generational Differences

Date: May 2014
Creator: Chen, Danxia
Description: This present study examined the structural validity of a Chinese version of Multidimensional Work Ethic Profile (MWEP-C), using a large sample of Chinese parents and their young adult children (N = 1047). Confirmatory factor analysis (CFA) was applied to evaluate the model fit of sample data on three competing models using two randomly split stratified subsamples. Measurement invariance for these two generational respondents was checked using differential item functioning (DIF) analysis. The results indicated that MWEP-C provided a reasonable fit for the sample data and the majority of survey items produced similar item-level responses for individuals that do not differ on the attributes of work ethic across these two generations. DIF items were detected based on advanced and successive iterations. Monte Carlo simulations were also conducted for creating threshold values and for chi-square probabilities based on 1,000 replications. After identifying the DIF items, model fit improved and generational differences and similarities in work ethic between parents and their young adult children were also identified. The results suggested that the younger Chinese generations have higher work ethic mean scores on the dimensions of work centrality and morality/ethics while they have similarities on time concept, self-reliance, delay of gratification, and hard work ...

Educational Experiences of Youth with And/or At-risk for Emotional and Behavioral Disorders Residing in Foster Care Settings

Educational Experiences of Youth with And/or At-risk for Emotional and Behavioral Disorders Residing in Foster Care Settings

Date: August 2013
Creator: Lewis, Calli G.
Description: Research examining the academic experiences of youth with emotional and behavioral disorders (EBD) residing in foster care (FC) is scarce. Research is warranted to understand the academic strengths, weaknesses, and school disciplinary experiences of youth with EBD residing in FC. Data from the National Survey of Child and Adolescent Well-being II (NSCAW II) included data on eight participants classified as EBD. Having a limited number of participants classified as EBD in the data set, I used participants’ scores on the Child Behavior Checklist (CBCL) to classify participants who may be at-risk for EBD. Analyses were conducted to determine if significant relationships existed between participants’ internalizing and externalizing scores on the CBCL and their (a) scores on assessments of academic achievement and (b) behavior problems leading to suspension or expulsion. Results indicated that participants’ scores on the CBCL were not predictive of their academic achievement or of their numbers of behavior problems leading to suspension or expulsion.

Educators' Perceptions of the Importance of Selected Competencies for Teachers of Students with Emotional and Behavioral Disorders and their Perceptions of Personal Proficiency

Educators' Perceptions of the Importance of Selected Competencies for Teachers of Students with Emotional and Behavioral Disorders and their Perceptions of Personal Proficiency

Date: December 2010
Creator: Wanyonyi-Short, Maureen N.
Description: This study investigated educators' perceptions of the importance of competencies for teachers of students with emotional and behavioral disorders and their own proficiency in the competencies. Participants included educators who had completed university-based coursework on emotional and behavioral disorders. Competencies from the Qualification and Preparation of Teachers of Exceptional Children study were correlated with CEC's content standards and knowledge skill sets for special education teachers of individuals with emotional and behavioral disorders. Participants ranked 88 competencies on importance and proficiency. Results revealed that educators' proficiency in competencies, their years of experience, and level of education contribute a significant percentage of variance in their ratings of the importance of competencies. Implications for further research are provided.

The Effect of Co-teaching on the Academic Achievement Outcomes of Students with Disabilities: a Meta-analytic Synthesis

The Effect of Co-teaching on the Academic Achievement Outcomes of Students with Disabilities: a Meta-analytic Synthesis

Date: August 2014
Creator: Khoury, Christopher
Description: Co-teaching has been, and continues to be, a growing trend in American schools since the late 1990s. As the popularity of this service delivery model increases, there is an imperative need for empirical research focusing on how co-teaching affects academic outcomes of students who receive special education services. Evidence regarding the academic outcomes of co-teaching is limited, and reports mixed results. The purpose of this study is to provide a synthesis of research examining academic outcomes of co-teaching on students who receive special education services. Quantitative information from each research report was coded, an overall effect size was computed, and a moderator analysis was conducted. Results suggest a significant effect (g = .281, k = 32, p < .05) of co-teaching on the academic outcomes of students with disabilities when compared to students with disabilities who did not receive instruction in co-taught settings; though a larger effect was found among dissertation reports (g = .439, k = 25, p < .001). Additionally, a significant effect was found when examining the academic outcomes of students in co-teaching compared to the academic outcomes of students in a resource classroom setting (g = .435, k = 27, p < .001. Lastly, effects were ...

The Effect of Naturalistic Behavior Strategies on the Quality of Social Interactions for Children with Autism

The Effect of Naturalistic Behavior Strategies on the Quality of Social Interactions for Children with Autism

Date: August 2012
Creator: Nichols, Susan Marie
Description: Autism is primarily a social disorder and deficits in social?orienting may be responsible for the failure of children with autism to initiate critical social behaviors. The purpose of this research was to improve the quality of social interactions of children with autism by implementing naturalistic behavior strategies intervention utilizing a multiple baseline design across four participants. Naturalistic behavior strategies comprised a comprehensive package of integrated components including: (a) intervention in the child’s natural environment; (b) child-initiated play activities ; (c) prompts to emit language; (d) shaping for all vocal approximations and (e) delivery of natural reinforcement with embedded social interactions to maintain learned behavior. In addition to intervention, generalization of child behaviors was assessed across untrained parents and/or caregivers in the same environment. Results indicated the effectiveness of naturalistic teaching strategies package in increasing (a) the frequency of vocal mands for all children, (b) the number of times that children initiated social engagement during manding, and (c) intervals of nonverbal dyadic orienting. These skills generalized across two untrained caregivers in the same clinical setting without any training from the interventionist. Two parents required training during the generalization phase in order for their child’s behaviors to maintain at levels demonstrated during ...

Effects of a Prototypical Training Program on the Implementation of Systematic Observational Data Collection on Iep Objectives for the Core Deficits of Autism Spectrum Disorders

Effects of a Prototypical Training Program on the Implementation of Systematic Observational Data Collection on Iep Objectives for the Core Deficits of Autism Spectrum Disorders

Date: May 2013
Creator: Harkins, Jessica L.
Description: Legal mandates and best practice recommendations for the education of students with autism spectrum disorders (ASD) emphasize the importance of systematic, ongoing observational data collection in order to monitor progress and demonstrate accountability. The absence of such documentation in decision-making on instructional objectives indicates a weakness in bridging the research-to-practice gap in special education. Utilizing a multiple baseline design across participants, the current study evaluated the effects of a prototypical teacher training program (i.e., workshop, checklist, in-classroom training with feedback, and maintenance with a thinned schedule of feedback) on the frequency of data collection on core deficits of ASD and the use of data-based decision-making. Results indicate increases in daily mean frequency of data collection following intervention. Maintenance and generalization indicates variable responding across participants. Effect size (Cohen's d) indicates a large, clinically significant effect of the training program. Results are discussed in relation to training models, maintenance, and future research.

Effects of the Why Try Social Skills Program on Students with Emotional and Behavioral Disorders at an Alternative Campus

Effects of the Why Try Social Skills Program on Students with Emotional and Behavioral Disorders at an Alternative Campus

Date: December 2010
Creator: Wilhite, Shannon
Description: Approximately 20% of students with emotional and behavioral disorders (E/BD) are sent to an alternative campus for their lack of social competence. Social skills training (SST) is an evidence-based intervention to help increase social competence for students with E/BD, but there is limited research that addresses SST for students with E/BD at alternative campuses. A mixed-methods design was utilized to examine SST at an alternative campus for students with E/BD. Pre-intervention data were collected for students' attendance, grades, office disciplinary referrals, and behavioral rating scales, after which, the Why Try SST program was implemented. Following the intervention, the same type of data were collected. Nonparametric statistics guided the quantitative analysis, because of the small population being studied. Differences from pre- to post-intervention were examined. Triangulation methods drove the qualitative data collection and analysis through observations, student interviews, and teacher interviews. Students exhibited significant differences from pre- to post-intervention in the number of office disciplinary referrals and several areas on the behavioral rating scales. Important insight into motivation and perceptions was gained through the observations and interviews.

Examination of Contributing Factors for Successful Postsecondary Transitions to Institutions of Higher Education for Youth with High-incidence Disabilities

Examination of Contributing Factors for Successful Postsecondary Transitions to Institutions of Higher Education for Youth with High-incidence Disabilities

Date: August 2013
Creator: Collins, Emerald R.
Description: Transitions are a natural part of life. Youth grow and develop physically, socially, psychologically, and intellectually during primary and secondary school years. The transition from secondary to postsecondary education is an important transition as youth not only move from high school to college, but also from adolescence to young adulthood. It is a time when young adults naturally desire to become more independent in pursuit of their personal dreams and aspirations. The purpose of this study was to examine the impact that academic, psychological, and social factors on youth with high-incidence disabilities as they strive to make successful postsecondary education transitions. Current trends indicate youth with high-incidence disabilities are graduating from high school and are attending vocational schools, colleges, and universities in increasing numbers. Transition barriers still limit many youth who could otherwise attend institutions of higher education regardless of disability type. Findings suggest academic and psychological factors most significantly predict successful postsecondary education transitions. Recommendations for improved transition planning and parental training are suggested.

A Hierarchical Regression Analysis of the Relationship Between Blog Reading, Online Political Activity, and Voting During the 2008 Presidential Campaign

Date: December 2010
Creator: Lewis, Mitzi
Description: The advent of the Internet has increased access to information and impacted many aspects of life, including politics. The present study utilized Pew Internet & American Life survey data from the November 2008 presidential election time period to investigate the degree to which political blog reading predicted online political discussion, online political participation, whether or not a person voted, and voting choice, over and above the predication that could be explained by demographic measures of age, education level, gender, income, marital status, race/ethnicity, and region. Ordinary least squares hierarchical regression revealed that political blog reading was positively and statistically significantly related to online political discussion and online political participation. Hierarchical logistic regression analysis indicated that the odds of a political blog reader voting were 1.98 the odds of a nonreader voting, but vote choice was not predicted by reading political blogs. These results are interpreted within the uses and gratifications framework and the understanding that blogs add an interpersonal communication aspect to a mass medium. As more people use blogs and the nature of the blog-reading audience shifts, continuing to track and describe the blog audience with valid measures will be important for researchers and practitioners alike. Subsequent potential effects ...

Date: August 2011
Creator: Moore, Olayinka Kofoworola
Description: This study investigated the effectiveness of the Home Instruction for Parents of Preschool Youngsters (HIPPY) program on school readiness. The HIPPY program uses home-based instruction to aid parents in teaching their children school readiness skills. The curriculum in this program includes literacy, math, and social skills. Texas Assessment of Knowledge and Skills assesses the academic achievement of students in different grade levels and in various subject areas. The chi square test revealed that the children in the HIPPY program were more likely to have higher passing rates on the first administration of TAKS Reading, Math and Science sections compared to non-participants. The implementation of early intervention and parental involvement programs such as HIPPY helps to facilitate students‟ success.

The Impact of Hippy on Maternal Self-efficacy

The Impact of Hippy on Maternal Self-efficacy

Date: August 2014
Creator: Nathans, Laura L.
Description: Parenting self-efficacy refers to the ability of parents to have confidence in their abilities to effectively parent their children. Parenting self-efficacy can be divided into two types: (a) general parenting self-efficacy, which is defined as a parent’s overall sense of ability to effectively parent; and (b) task-specific parenting self-efficacy, which is defined as a parent’s confidence level to perform specific parenting tasks, such as teaching and nurturing (tested in this study). The study applied Bronfenbrenner’s bioecological theory to an analysis of (a) the effect of the HIPPY program in interaction with family and neighborhood variables on parenting self-efficacy and (b) the effect of the interaction of family and neighborhood variables on parenting self-efficacy. A group of 138 HIPPY mothers and a group of 76 comparison mothers who did not receive HIPPY services were surveyed. The sample was largely Hispanic. Results indicated HIPPY predicts task-specific parenting self-efficacy for teaching tasks, but not general parenting self-efficacy or task-specific efficacy for nurturance. Many family variables that reflected Hispanic family values were unique predictors of all three types of parenting self-efficacy, both in analyses involving interactions with HIPPY and with neighborhood variables. Neighborhood variables solely predicted general parenting self-efficacy. Moderation effects were found for ...

The Impact of Teacher Perception of Cultural Competence on the Instructional Decision Making of English As Second Language (ESL) Students

The Impact of Teacher Perception of Cultural Competence on the Instructional Decision Making of English As Second Language (ESL) Students

Date: May 2014
Creator: Lim, Okyoung
Description: Recent research suggests that culturally responsive teaching (CRT) practices have the potential to increase student educational outcomes, as well as to reduce unnecessary or inappropriate placement referrals. Examination of the core components in CRT, teacher efficacy and cultural competence, is proposed to be a critical step to reduce unwarranted referrals of culturally and linguistically diverse students. However, there is limited empirical support for the relationship between CRT and instructional referrals, and even among existing studies there is inconsistency regarding the relation of these constructs. The purpose of this study is to examine teacher factors (i.e., teacher role, degree earned, years of teaching, ESL certification held, language proficiency and ethnicity) as a predictor of teacher competence, and the role these factors play in teachers’ referral decision making. To investigate these relationships, a national sample of elementary teachers (N = 258) completed a survey addressing their background, profession endorsements, sense of teaching efficiency, and the instructional decisions they would make in the scenarios presented. The results of this study revealed that teacher role (i.e., general, ESL or special educator) and ESL certification were important predictors of teacher competency. A statistically significant mean difference in teacher competency was found between teachers with and ...

Date: August 2013
Creator: Ponce, Hector F.
Description: The Association of Research Libraries (ARL) provides an option for librarians to administer a combination of LibQUAL+® and LibQUAL+® Lite to measure users' perceptions of library service quality. LibQUAL+® Lite is a shorter version of LibQUAL+® that uses planned missing data in its design. The present study investigates the loss of information in commonly administered proportions of LibQUAL+® and LibQUAL+® Lite when compared to administering LibQUAL+® alone. Data from previous administrations of LibQUAL+® protocol (2005, N = 525; 2007, N = 3,261; and 2009, N = 2,103) were used to create simulated datasets representing various proportions of LibQUAL+® versus LibQUAL+® Lite administration (0.2:0.8, 0.4:0.6. 0.5:0.5, 0.6:0.4, and 0.8:0.2). Statistics (i.e., means, adequacy and superiority gaps, standard deviations, Pearson product-moment correlation coefficients, and polychoric correlation coefficients) from simulated and real data were compared. Confidence intervals captured the original values. Root mean square errors and absolute and relative biases of correlations showed that accuracy in the estimates decreased with increase in percentage of planned missing data. The recommendation is to avoid using combinations with more than 20% planned missing data.

Knowledge and Confidence of Speech-Language Pathologists Regarding Autism

Knowledge and Confidence of Speech-Language Pathologists Regarding Autism

Date: December 2010
Creator: Ray, Julie M.
Description: The increased prevalence rate of autism has immense implications for speech language pathologists (SLPs) who are directly involved in the education and service delivery for students with autism. However, few studies have documented the effectiveness of the knowledge and confidence of SLPs regarding autism. The purpose of this study was to measure the knowledge and confidence of SLPs regarding autism and the extent to which their educational and professional training prepared them to work effectively with this population. An online survey was administered to and returned by 336 SLPs nation-wide. Two multiple linear regressions were conducted to determine the variables that explained overall knowledge and confidence. The number of students with autism on one's caseload explained most of the variance. Independent sample t-test results depicted knowledge and confidence scores of SLPs who were behaviorally trained versus those who were not behaviorally trained. SLPs who were behaviorally trained had higher mean scores on measures of knowledge and confidence when compared to those without formal behavioral training. Finally, a bivariate correlation was conducted to explore the relationship between knowledge and confidence of SLPs, however, results were not statistically significant.

Knowledge and Training in Autism Spectrum Disorders Among Special Education Administrators.

Knowledge and Training in Autism Spectrum Disorders Among Special Education Administrators.

Date: December 2010
Creator: Hughes, Heather L.
Description: A significant rise in the number of students with autism spectrum disorders (ASD) served in today's schools requires special education administrators to possess knowledge in this area. The purpose of this study was to determine the general knowledge of special education administrators concerning ASD and knowledge of educational programming, to explore their educational training and professional development experiences in ASD, to identify the training needs of special education administrators in ASD, and to determine if knowledge, training and experience in ASD predict litigation. Using survey methods, data were collected from a sample of 106 special education administrators in Texas. Data revealed special education administrators were most knowledgeable of general characteristics, common myths, and instructional strategies, and less knowledgeable of eligibility criteria. Knowledge regarding educational programming for learners with ASD produced mixed results. Logistic regression analysis revealed general autism knowledge, knowledge of educational programming, training, and experience in ASD were not factors predicting litigation. Although results indicated none of the factors explored in this study were predictors of litigation, areas of need regarding professional development were identified. Implications for future research are also discussed.
