Item Using Discourse to Improve the Quality of Student Talk and Historical Argumentative Writing(2024) Otarola, Josue; De La Paz, Susan; Special Education; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Frameworks that connect to the Common Core State Standards for English Language Arts and Literacy in Social Studies, such as the College, Career, and Civic Life (C3) Framework for Social Studies States Standards, highlight the need to engage in inquiry-based instruction (NCSS, 2013). Participation in such inquiry requires students to engage in disciplinary thinking and to articulate that thinking to others, both verbally and in writing. However, such disciplinary thinking does not come natural to students (Wineburg, 1991). Thus, students require instruction in disciplinary thinking to learn its complexities and nuances. Once students can engage in disciplinary thinking, they can communicate it and participate in valuable discourse. Therefore, the current dissertation was conducted to explore how students use discourse to engage in argumentation and historical thinking. Chapter 2 of the dissertation is a research synthesis of studies that use discourse to improve learning outcomes in primary and secondary science and social studies classrooms. The purpose of the synthesis was to determine the impact of argumentative discourse on students’ learning outcomes and to understand the instructional components teachers use when holding discourse. Asterhan & Schwarz’s (2016) Argumentation for Learning (AFL) framework guided the research synthesis and the subsequent multiple-case study. Results indicate that discourse can be improved by using multiple instructional groupings, incorporating explicit instruction, modeling, graphic organizers and technology, and engaging students in deliberation. Chapter 3 offers findings from a multiple-case study that was designed to explore how argumentation inhibitors and enablers moderate dialogue characteristics and learning outcomes and to provide a rich description of discourse in ninth-grade US History classrooms with academically diverse students. More specifically, the study captured how students engaged in argumentative discourse and historical thinking using two different discourse structures. The study used a cross-case analysis (Yin, 2018) to compare the discourse across three cases. Each case included a teacher and four students. The first case occurred in a co-taught class, the second case included the same teacher in an honors class, and the third case included a different teacher in an honors class. The first and second case used a modified structured academic controversy (SAC), while the third case used Johnson and Johnson’s (1988) approach to SAC. The multiple-case study and the research synthesis informed the practitioner manuscript provided in Chapter 4. The manuscript details how teachers can use structure and supports to improve student participation and historical thinking in classroom discourse, especially for students with disabilities (SWD) and other struggling learners. The current dissertation provides several important findings. First, my synthesis indicated that students achieve higher learning outcomes when teachers use multiple instructional groupings, students engage in deliberative discourse, and teachers provide students with explicit instruction, modeling, and graphic organizers. Second, the findings from the multiple-case study offered insight into how students of differing academic abilities engage in argumentative discourse and historical thinking. Students of all academic abilities participated at high levels and engaged in deliberative argumentation, though there were differences in the quality of historical thinking skills. The instructional approach used in the multiple-case study is further expanded in the practitioner manuscript. Areas for future research are discussed in the dissertation.Item Implementing Universal Design to Support Neurodivergent Students in Undergraduate Introductory Computer Science Classes(2024) Kaplitz, Emily Mae; Weintrop, David; Computer Science; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)There has been an increase of both neurodivergent students and enrollment in Computer Science programs in higher education. These increases have brought attention to two separate challenges: neurodivergent college students struggle more compared to their neurotypical peers and many students struggle in introductory computer science courses. This study considers both of these realities by investigating the impact of using Universal Design for Learning (UDL) strategies to revise introductory computer science courses. In doing so, it seeks to understand if and how UDL strategies can support neurodivergent students, along with their neurotypical peers, in succeeding in historically challenging academic contexts. This study focused on three questions: How can universal design for learning principles be implemented into an introductory programming course?, How does updating an introductory programming course to follow the universal design for learning framework affect the experience of students?, and What are the experiences of neurodivergent and neurotypical students after updating an introductory programming course to follow the universal design for learning framework? This study was conducted over three semesters of introductory programming courses. The first semester served as a control for the study where no changes were made to the course. In the following semester, the course's lecture slides were updated to be more accessible following Universal Design for Learning principles. In the third and final semester, the course’s lecture slides were updated to be more accessible, and supplementary slides were created for the projects to help students understand what is being asked of them. To assess the interventions, student surveys, interviews, and grades were analyzed. The findings serve as a demonstration of how to modify lecture slides and create programming project slides to apply universal design for learning principles and show the students had considerably better experiences and greater academic success in the course that applied universal design for learning principles. These benefits were recorded for both neurodivergent and neurotypical students, showing that universal design for learning principles benefits all students. The implications of these findings are considered and recommendations for improving introductory programming instruction are discussed. This work advances our understanding of how to help students comprehend foundational computer science concepts and develop the necessary computer science practices to excel in the field.Item Literacy Based Behavioral Interventions for Autistic and Neurotypical Children(2024) Pepkin Dataram, Sara Anne; Kang, Veronica; Special Education; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The neurodiversity model of disability is a relatively new approach to teaching and working with autistic individuals. As a result, many interventions align with earlier models of disability, such as the medical and social models, and aim to assimilate autistic individuals among their neurotypical peers rather than celebrate their differences as one of life’s natural diversities. This study investigates how educators can create Literacy Based Behavioral Interventions (LBBIs) that align with the neurodiversity paradigm and foster equitable friendships between autistic and neurotypical children. I conducted focus groups with 34 autistic middle school and high school students and eight educators to determine how to feasibly meet autistic students’ social needs. Themes found across these focus groups included autism education for teachers and neurotypical peers, barriers to communication, and the impact of social stigma against autistic individuals. These findings indicate a need for LBBIs and overall classroom environments that amplify autistic perspectives and are not rooted in neurotypical standards.Item In Pursuit of a Nonpublic Special Education Placement(2024) Healy, Charlotte Eileen; Scribner, Campbell F; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Although the Individuals with Disabilities Education Act (IDEA) intends parents to be equal members of the team that makes their child's Individual Education Plan (IEP), parents face barriers to participation, particularly exclusionary procedures, school structures, professional behaviors, and racial and cultural biases. Little wonder that some seek placements outside the public school system. However, IDEA also mandates that students receive services in the “least restrictive environment,” which means alongside peers without disabilities to the maximum extent appropriate. This dissertation is an exploratory, qualitative study of parents who pursue publicly funded special education placements in nonpublic institutions for students with autism spectrum disorders (ASD). This research documents parents’ reasons, perceptions, and experiences when seeking a nonpublic placement, as well as their strategies and challenges. The questions, and my interpretation of responses, are informed by Pierre Bourdieu’s (1985) socio-cultural capital theory, as well as Audrey A. Trainor’s (2010a, 2010b) descriptions of social and cultural capital use when advocating for children with disabilities. This study found parents of children with ASD sought nonpublic placement only when significant issues arose in their child’s public school, particularly around their child’s safety or lack of meaningful improvement, and only after their efforts to resolve these issues failed and their distrust of school and district personnel grew. No longer focused on coming to a consensus or compromise with their child’s IEP team, parents began an advocacy process that involved: a) consulting or retaining professional representation (attorneys, professional advocates, and/or educational consultants); b) building and presenting the argument that the school district was and could not providing a free and appropriate public education (FAPE); c) securing a placement in a nonpublic school.Item Implementation Issues Impeding Evidence-based Instruction for Students with Significant Cognitive Disabilities in One Public School System(2023) Stephanson, Janet; McLaughlin, Margaret J.; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)For over 50 years, providing relevant and individualized instruction for students with significant cognitive disabilities (SSCD) has challenged school systems because of the heterogeneity of the population and the complicated nature of their learning characteristics, warranting the implementation of specific instruction using targeted, evidence-based instruction, not common practice in most school settings. The intention of this mixed-method Participatory Action Research (PAR) study is to investigate the barriers to providing evidence-based practices in District A while creating a framework of the PD required to increase teacher capacity to deliver the instruction. An Innovation Configuration Matrix (IC Matrix) created by Browder et al. (2014) will be used as the foundation for the study, as it details the evidence-based practices (EBPs) for students with severe disabilities by detailing what instruction is needed, how the instruction should be provided, and what supports are needed for the instruction to occur. The PAR process will occur through the administration and evaluation of a survey for all teachers of SSCD, followed by three convenings of a group of nine District A teachers of SSCD who will use the information of the survey, the IC Matrix, and federal and state guidance to create a PD Framework detailing the learning needs for all teachers of SSCD in District A.Item Trajectories of Clinician Competence and Student Engagement During an Adolescent ADHD Intervention(2023) Sommer, Samantha Lynn; Teglasi, Hedwig; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)School-based organization, time management, and planning skills-related (OTMP) interventions have been developed to address academic and organizational difficulties students with Attention-Deficit/Hyperactivity Disorder face (ADHD), especially when entering secondary school (DuPaul et al., 2012; Evans et al., 2018; Villodas et al., 2014). For OTMP interventions to be reliably administered, interventionists must be appropriately trained to not only implement session procedures that adhere to intervention protocol, but to also adjust their responses to individual students to maintain quality interactions, which is referred to as competence (Goense et al., 2016; Perepletchikova et al., 2007). This study tested the hypothesis that the constructs, interventionist competence and student engagement, would significantly change over the course of a 16-session school-based intervention for adolescents with ADHD and academic challenges. Specific student characteristics were also expected to interact with initial levels or changes in competence and engagement over time. Using an archival dataset (N= 111) and latent growth modeling, findings revealed that neither competence nor engagement changed significantly over time. However, initial levels of both constructs significantly varied. Further conditional growth modeling found that greater ADHD symptom severity negatively contributed to competence and that internalizing symptoms contributed uniquely and positively to competence. Although interventionist competence and student engagement did not exhibit significant change over time, certain student factors were associated with the quality of interventionists responses to students and with the degree to which students remain engaged with intervention materials.Item Examining the Disproportionate Representation of Bilingual Children in Special Education(2022) Ortiz, Jose A; Cummings, Kelli D; Special Education; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Chapter 2: Nonword repetition has been endorsed as a less biased method of assessment for children from culturally and linguistically diverse backgrounds, but there are currently no systematic reviews or meta-analyses on its use with bilingual children. The purpose of this study is to evaluate diagnostic accuracy of nonword repetition in the identification of language impairment (LI) in bilingual children. Using a keyword search of peer-reviewed literature from several large electronic databases, as well as ancestral and forward searches, 13 studies were identified that met the eligibility criteria. Studies were evaluated on the basis of quality of evidence, design characteristics, and reported diagnostic accuracy. A meta-regression analysis, based on study results, was conducted to identify task characteristics that may be associated with better classification accuracy. Diagnostic accuracy across studies ranged from poor to good. Bilingual children with LI performed with more difficulty on nonword repetition tasks than those with typical language. Quasiuniversal tasks, which account for the phonotactic constraints of multiple languages, exhibited better diagnostic accuracy and resulted in less misidentification of children with typical language than language-specific tasks. Evidence suggests that nonword repetition may be a useful tool in the assessment and screening of LI in bilingual children, though it should be used in conjunction with other measures. Quasiuniversal tasks demonstrate the potential to further reduce assessment bias, but extant research is limited. Chapter 3: The disproportionate identification of language-related disorders in schools, including communication disorders and specific learning disability, is an ongoing problem for bilingual children, with evidence of both over- and underrepresentation. Previous research has uncovered distinct identification patterns for emergent and English-proficient bilinguals, as well as differences in identification rates across grades. However, there is limited information about disability identification for different groups of bilinguals across grades. Thus, the purpose of this study is to examine the prevalence and incidence of language-related disorders in emergent and English-proficient bilinguals in elementary school. Using a nationally representative, individual-level, longitudinal data set, this study examined representation in language-related disorder categories, as well as identification rates by year. This study also examined individual- and school-level predictors of disability identification for bilingual children. Results indicate that emergent and English-proficient bilinguals exhibit distinct patterns of language-related disorder identification. Emergent bilinguals experienced a disproportionate increase in disability identification rates in third grade, resulting in significant overrepresentation in subsequent grades. By fifth grade, emergent bilinguals experienced approximately twice the odds of being identified with a language-related disorder, compared to monolinguals. English-proficient bilinguals, on the other hand, were underrepresented in language-related disorder categories in early elementary school grades, but experienced identification rates similar to monolinguals by fifth grade. Outcomes from this study provide insight into patterns of language-related disorder identification for bilinguals that have not been addressed in previous research. The implications for education practice and policy are discussed. Chapter 4: The disproportionate representation of bilingual children in special education is an ongoing issue in US schools, with evidence of both over- and underrepresentation. Identification rates of language-related disorders, including communication disorders and specific learning disability, are particularly relevant for bilingual children given the challenges associated with differentiating language difference from disorder and the possibility of misidentification. School-based speech-language pathologists are well positioned to address the issue, but many do not engage in practices that may reduce disproportionate disability identification. The purpose of this practitioner paper is to provide school-based clinicians with an evidence-based model for addressing disproportionality in bilingual children, with a focus on prevention. This paper provides a review of the literature on the topic and integrates information from relevant studies to provide a clear depiction of the nature of the problem. In addition, this paper describes a model of disproportionality prevention, and provides a set of evidence-based methods that clinicians can employ. Topics include, pre-referral intervention, early identification, parent engagement, and collaboration. By adopting the methods described in this paper, school-based speech-language pathologists can strengthen their ability to meaningfully address many of the issues that contribute to over- and underrepresentation of bilingual children in special education.Item Addressing the Employment Gap with Workplace Supports for Transition-Age Autistic Youth and Young Adults(2022) Chen, Briella Baer; Yakubova, Gulnoza; Special Education; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Transition-age youth and young adults diagnosed with autism spectrum disorder (ASD) have notably low rates of employment, compared to not only their peers without disabilities, but also compared to their peers with different disabilities. As such, the adoption of additional workplace tools and accommodations to better support transition-age autistic individuals is needed. This dissertation aimed to address this employment gap through examination of different employment supports for transition-age autistic youth and young adults. Chapter 2 is a synthesis of the literature on the use of video-based intervention (VBI) to teach vocational skills to transition-age autistic youth and young adults. Using both qualitative and quantitative methods, this synthesis evaluated 22 studies, finding VBI to be an effective vocational training and support tool for this population. However, the synthesis also identified a lack of authentic implementation of VBI for vocational skills, or implementation by practitioners in real workplace settings. Chapter 3 is an experimental study which sought to examine the effectiveness of VBI when implemented in authentic employment settings and how to train practitioners to do so. The study had two aims: to evaluate the effects of a behavioral skills training (BST) package on vocational support practitioners’ creation and implementation of VBI, and to evaluate the effects of the resulting practitioner-created and -implemented VBI on the vocational skill acquisition of transition-age autistic adults in authentic workplace settings. This study ultimately found that both the BST package and resulting VBI were effective and socially valid. Chapter 4 is a qualitative study that sought to expand upon the topic of workplace supports for autistic youth and young adults by interviewing 12 currently or formerly employed transition-age autistic individuals. The qualitative study had two major aims: to determine what transition-age autistic individuals identify as key workplace supports, as well as their experiences with and views of technology-based work supports, specifically. Through qualitative interviews and analysis, the study identified six major themes for key workplace supports, and four for technology-based supports. The themes, their related subthemes, and practical implications for employers are discussed.Item AN INVESTIGATION INTO THE RELATIONSHIP BETWEEN CO-TEACHING AND STUDENT ENGAGEMENT(2022) Clancy, Erin; Wexler, Jade A; Special Education; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Federal law mandates that students with disabilities (SWDs) receive specially designed instruction (SDI), which includes the adaptation of the content, methodology, or delivery of instruction to meet SWDs’ unique needs, to ensure access to the general education curriculum (Rodgers et al., 2021; Ten Napel, 2017) within the least restrictive environment (Individuals with Disabilities Education Act, 2004). One common service delivery model for the many SWDs in the general setting education is co-teaching, wherein a content-area teacher (CAT) and a special education teacher (SET) share instructional responsibilities. The CAT and SET can use a variety of models (e.g., team teaching) to implement co-teaching. Although research showing the effectiveness of co-teaching for improving student achievement is limited (Clancy & Wexler, see Chapter 2; Murawski & Swanson, 2001), co-teaching has the potential to increase student engagement due to the defining features of certain co-teaching models that may benefit SWDs. Increasing student engagement is important as engagement is positively correlated with student outcomes, such as retaining information, graduating from high school, and pursuing postsecondary education (Finn, 1993).To better understand the extent to which different co-teaching models are implemented and which teacher (i.e., CAT or SET) leads instruction during the implementation of certain co-teaching models, it is necessary to extend previous research (e.g., Wexler et al., 2018). Additionally, given the importance of engagement and the potential relationship between co-teaching and engagement, it is necessary to explore whether specific co-teaching models are associated with higher levels of student engagement. Thus, there are two goals of the current dissertation. The first goal is to investigate the frequency of use of each co-teaching model and the extent to which each co-teacher leads instruction during the implementation of certain models. The second goal is to explore the relationship between each observed co-teaching model and student engagement. The current manuscript includes a statement of the problem, theoretical framework, literature synthesis, research questions, methodological approach, results, and discussion for the study. I provide this information sequentially over five chapters. Chapter 1 introduces the problem the current dissertation seeks to address. This chapter provides an overview of current service delivery models for SWDs in the general education setting, including co-teaching, and includes extended descriptions of each of the six co-teaching models. Chapter 1 also provides an overview of the research on student engagement. The chapter closes by providing a statement of the problem and the theoretical framework. Chapter 2 of the dissertation presents a literature synthesis of experimental studies investigating the effect of co-teaching on student achievement. The purpose of the synthesis is to extend a previous synthesis (Murawski & Swanson, 2001) and provide updated knowledge on the impact co-teaching has on student outcomes. While co-teaching has been a commonly used service delivery model, information about its effectiveness is limited. This synthesis contributes a new understanding of co-teaching as more than 20 years have passed since Murawski and Swanson’s initial synthesis. In Chapter 3, I describe the methodological approach of the empirical study. I used archival observation data to determine which co-teaching models were used most often and which teacher led instructional delivery for specific models (i.e., one-teach-one observe, one teach-one assist, one teach-one monitor). I then investigated the relationships between student engagement and the observed co-teaching models. Chapter 4 provides the results of the empirical study. Results from the observation data showed that team teaching and one teach-one assist were the most relied upon co-teaching models. Additionally, the CAT typically led instruction during implementation of one teach-one assist and other independently driven models. Furthermore, there was a moderate significant relationship between engagement and the co-teaching models. Then, Chapter 5 contextualizes the findings within similar research and the theoretical framework. The findings of the first research question on observed co-teaching models align with similar recent research. The investigation into the relationship between co-teaching models and student engagement aligned with the theoretical framework. Specifically, student engagement was observed more frequently in models where both teachers drove instruction (i.e., alternative, station, and team teaching). In closing, I provide implications for practice as well as recommendations for additional research and present the conclusion.Item An Investigation of the Impacts of State-Mandated Benchmarks on Special Education Eligibility Identification of African American Students(2022) Gruver, Marcella Lemire; McLaughlin, Margaret; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Education is critical to a healthy and productive society as it increases the knowledge and outcomes of each of its citizens. Nonetheless, disproportionality has historically been an issue in U.S. public education. Despite its longevity, it is a problem that must be remedied to prevent unnecessary stigmatization, segregation, and low expectations (Losen & Orfield, 2002; Losen & Welner, 2002). Educational reforms established to protect student groups may in fact yield negative outcomes. Policy addressing disproportionality of minority students in a disability category could result in reduced disproportionality in that category; however, other categories may show an increase in disproportionality (Oswald et al., 2002). The purpose of this study was to investigate the impact on District A’s special education referral and evaluation practices of the state mandated risk ratio benchmarks for identifying significant disproportionality in special education identification. Decisions regarding referral for special education evaluation and subsequent determination of eligibility to receive services for most students happens at the school level. Therefore, a state policy that establishes a risk ratio threshold for determining if significant disproportionality among subgroups of students exists is a policy instrument that requires changes at both the district and individual school levels to achieve its goal. This study used a mixed methods approach and used data analysis, focus groups, individual interviews, and document analysis to investigate the impact of the state mandated risk ratio benchmarks for identifying significant disproportionality on the special education referral and evaluation practices at the district and school-based level in District A. Data from this study helped to identify areas where the district should focus its efforts to solve its significant disproportionality of African American students identified as having an IDEA disability in the categories of Specific Learning Disability or Emotional Disability.
