The purpose of this mixed method study was to better understand undergraduate students' perceptions of international teaching assistants (ITAs) at a major research institution. For the purpose of this inquiry data were collected from surveying a sample of 436 of undergraduate students from different colleges and at different class levels. Survey data were analyzed both qualitatively and quantitatively. Through the qualitative analysis of the open-ended survey data, undergraduate students' perceptions were derived from their responses, which resulted in themes both established in previous research (e.g., language), and original ideas (e.g., learning to understand ITAs language). Qualitative analysis of the survey data revealed that undergraduate students' perceptions of ITAs were varied and complex. For example, one perception identified was the connection of language to pedagogic difficulties, while another perception focused on the interactive construct of communication. Further, the quantitative analysis revealed a statistically significant relationship between these two relational perceptions and undergraduate students who reported having experienced problems with ITAs in their classes. More specifically, students who indicated that they did not have problematic experience with ITAs were not very likely to articulate perceptions that were relational, whereas more students that did report having a problem in courses taught by ITAs articulated perceptions that involved an interaction (e.g., communication and language as a barrier interfering with pedagogic performance of ITAs). The findings from this study thus provide a critical understanding of undergraduate students' perceptions from their perspectives. In addition, the finding that language-pedagogy and communication were connected by undergraduate students who had encountered problems with ITAs, suggests that instead of ITA education programs addressing the challenges of accommodating the needs of individual departments and/or colleges in a university (Jia & Bergerson, 2008), ITA education would benefit more from focusing on language in relation to pedagogy.

The Physician Assistant and Nurse Practitioner professions initially began in response to healthcare shortages after the Vietnam War in the 1960s. Highly trained combat medical personnel developed into highly skilled PAs, while during this same time nurses began advanced practices that ultimately evolved into the position of NPs. Since this time, the roles and responsibilities delegated to each of these fields have drastically evolved, and are expected to continue to do so in the face of current health care reform under President Obama's Patient Protection and Affordable Care Act initiated in 2010. Originally perceived as "understudies" to physicians, PAs and NPs have become much more trained in their expertise, respected in their roles, and autonomous in their practice. Due to this, it has been predicted that PAs and NPs will become the major primary care providers in the face of increasing demands in this area of medicine. Large numbers of aging populations and up to 32 million newly insured patients seeking healthcare, coupled with physician shortages, have increased demands on PAs and NPs to fill these employment gaps. As there has been an increased demand on the PA and NP profession, there has been a paralleled increase in the number of educational programs producing graduates, larger class sizes, and larger numbers of PAs and NPs entering the workforce. The problem is posed when PAs and NPs, who desire to pay off student loans quickly and, understandably, seek high wages and professional advancement, pursue specialty and subspecialty employment versus filling in primary care gaps as anticipated. As the roles of PAs and NPs change, and more is expected of them in terms of practice and reliability, there are barriers to their growth. Professional tensions between these providers and physicians, poor understanding of what roles PAs and NPs hold by the public, unequal reimbursement for comparable services, and strict state legislation that limits the scope of practice of both PAs and NPs all inhibit these healthcare professionals from practicing to their fullest potential. This, in turn, may hinder persons becoming PAs and NPs from funneling into the ever increasingly demanding primary care field of medicine, and may pose future problems as patient populations increase under the Affordable Care Act. This paper assesses the current roles and responsibilities of PAs and NPs, how each profession is expected to grow, and the evolution of these healthcare providers as the potential "solution" to primary care needs. Statistics regarding current distributions of PAs and NPs in practice, educational expansion, obstacles that these professions must overcome, and the capabilities of PAs and NPs alike are analyzed, and conclusions drawn on what the contributions of these healthcare professionals may be in the future. Overall, it is expected that PA and NP presence in the medical field will undoubtedly increase. Whether these professionals will serve as an adequate source of primary care providers in the face of increasing demands imposed by the Affordable Care Act is yet to be seen, however. Barriers including professional tensions, reimbursement policies, wages, and strict state restrictions on the scope of practice of these individuals will need to be addressed. While it is projected that PAs and NPs will "solve" the current and future primary care physician shortage, this fact truly remains to be seen.

This research gave voice to teaching assistants, exploring their experiences and perceptions, in terms of their backgrounds, roles and responsibilities, experiences whilst studying on an NVQ programme, support from their schools, their aspirations and the progression routes available to them. A small-scale phenomenological study approach was adopted, aimed to interpret and explain human actions and thought through descriptions, capturing first person accounts. Qualitative data was collected from focus group interviews. The research found that the main entry route into the role of teaching assistant was that of parent-helper at the school their child(ren) attended. Previous employment was varied, however, previous skills and experience was not drawn upon or utilised by the schools. Differences in job titles were not reflected by the roles performed by the participants. Support from their schools for undertaking qualifications was limited and participants had little knowledge of progression routes available to them. The research concluded that there is a need for a transparent career structure, which indicates levels of responsibility. Linked to this should be nationally recognised qualifications, which every member of support staff would have to gain, at the appropriate level for the role they fulfil. Wages should reflect the roles and associated qualifications, bringing about a clearer picture of the job of ‘teaching assistant’.

Six hundred sixty-six students were queried at the University of North Texas. The appropriate use of nonverbal behaviors of international and U.S. American TAs was surveyed. An eleven item questionnaire (Teacher Nonverbal Measure) was utilized. These questions were tested by an ANOVA. Data indicated that international TAs are less likely to use appropriate nonverbal behaviors than U.S. American TAs. Thus, it is possible to assume that international TAs are more likely to be perceived as using inappropriate nonverbal behaviors than U.S. American TAs. Also, communication competence was investigated. The Communication Skill Rating Scale was utilized and tested by ANOVA. Results indicate that international TAs are viewed as significantly less competent than U.S. American TAs.

The study (paper 1) sets out to explore TAs perceptions of their practice by investigating the incidence of scaffolding present in their work with students. A mixed- methods approach to data collection involved a focus group of 12 TAs, and structured classroom observations followed by semi-structured interviews of 7 TAs. This allowed the researcher to discuss what was observed as well as discover their views on their and other TAs’ practise. Varying degrees of mediation were observed: scaffolding, acceptance but challenging pupil’s response, bridging, exploring systematic thinking, and using process oriented questions. Very rarely did TAs give answers to problems in isolation. TAs often were responsible for supporting students in regulating their behaviour, and indicated that their focus was not solely on students academic attainment but more so on their emotional and social development as well. Implications for practise within the school system are explored. Following findings from paper 1, this study (paper 2) sets out to further explore the roles of TAs from the perspectives of students and parents. TAs indicated that a significant aspect to their role was developing the social and emotional wellbeing of the students they supported. This paper explores to what aspect those views were shared and valued by students and parents. A mixed-methods approach to data collection involved a focus group of 3 students, 21 parental questionnaires, and semi-structured interviews of 7 TAs. 64% of parents indicated that TAs provide social and emotional support to their students, and 95% of parents indicated that the role was important in supporting their children in having successful school experiences. Students indicated that TAs knowing them well was one of the most important aspects needed to support them. The theme of ‘student nurture’ is explored, as TAs perceive this to be one of the main aspects of their role. Implications for practise within the school system are explored.

This thesis describes an investigation into the outcomes of a developmental project focussed on improving the word reading skills of a group of (n=77) secondary school students across five different school settings in a South West of England Local Authority. The 'Plymouth Precision Teaching Project' was conducted during the 2007/8 academic year commencing in September 2007 through to April 2008. The project involved the delivery of regular Precision Teaching (PT) programmes across two cohorts (1 and 2) of students by Teaching Assistants (TAs) in each school who themselves received ongoing training and support throughout the project. This thesis reports on three inter-connected aspects of research stemming from the project: Aspect One considered the impact of PT interventions delivered by trained TAs on groups of secondary school students with literacy learning needs through a quasi-experimental design. Aspect Two investigated the adaptations made by TAs within PT programmes to improve student word reading skills; from here a framework for systematic teaching adaptations was formulated, trialled and reviewed. Aspect Three drew on the experiences of school staff and their learning throughout the initiative. The value of participating in the research was investigated through exploring TAs’ reflections on the development of their understanding of the processes and practices surrounding ‘teaching and learning’. Outcomes of the research point to the continuing contribution of PT to addressing basic reading skill needs through heightened structure to intervention delivery, promotion and scrutiny of ‘treatment fidelity’ and an ongoing, systemic approach to the development of staff skills. This thesis also emphasises the mutual benefits that a collaborative project such as this can bring about; not only can staff contribute to the development of intervention approaches and provide high-quality interventions, but they can also develop their professional knowledge too. As a venture networking schools, a local authority educational psychology service and a university department, it is suggested this thesis reflects a description of the ground modernised educational psychology services should seek to occupy more and more.
