Information visualization tools provide visual representations of data (commonly known as visualizations), textual representations of data and interactive operations on both these representations. It is possible, in theory, to make use of only the textual representations in order to detect trends and patterns in data. However, it would be extremely laborious and ineffective and it defeats the purpose of a visualization tool. Novices have had the problem of relying on text and failing to successfully detect trends in data because it was too laborious. We want users to effectively use visual representations to detect trends in data. Information visualization tools have been shown to be successful with experts. But can novice users using a visualization tool for the first-time, adopt visualization-based strategies to finding trends and patterns in data? This thesis derives a framework of learnable elements in an interactive coordinated-view visualization tool. This framework provides an outline of prerequisites to be learned in order to effectively use visualizations. That is, the new aspects of visualization tools must be mastered so that novices can use the tool effectively. Three interface design principles are derived to make these elements learnable to novice users: • The data-first approach - Provide a prominent overview of all available data, as opposed to showing only visualizations. This helps understand the data structure - this may be essential knowledge in being able to navigate to required data attributes. • The "less visualization, more explanation" approach - Show more explanations of visualizations at the expense of being able to pack in more visualizations. Explanations help identify how data is mapped onto visual marks, a crucial step in understanding visualizations. • The "predetermined task-based coordinations" approach - Provide separate predetermined sets of coordinated visualizations that help achieve different tasks. This is different from techniques that simply present all visualization types and expect users to choose coordinations according to tasks. Two versions of Datamaps visualization tool for Census data were tested. Both were equivalent in functionality and the kinds of visualizations offered. But the new version was specifically designed based on the three design principles. A usability study showed that the version that was implemented according to the three design principles successfully led novices to effectively use visualization-based strategies to detect trends and patterns in data. / Master of Science

The objective of this study was to describe the perceptions of the support and professional development activities for and needed by novice school administrators (NSAs) in southwestern Virginia. A qualitative methods research design was used to collect and examine data. The researcher interviewed 22 NSAs from 11 different public school divisions in the Virginia Department of Education's (VDOE's) Regions 6 and 7 in southwestern Virginia. An interview protocol consisting of 15 questions was used to collect data on the perceptions of the NSAs. From the research collected, a list detailing the support and professional development (PD) activities for NSAs in southwestern Virginia was created. The support and PD activities were grouped into the categories of (a) support and PD activities provided for NSAs, (b) effective support and PD activities provided for NSAs, (c) support and PD areas of need for NSAs, (d) support and PD activities that the NSAs provided for themselves, (e) factors limiting the support and PD of NSAs. The data collected from this study were strategically placed into a design of seven NSA support and PD areas that school divisions could utilize to create a program, or further develop a program for NSAs. Those areas correlated with the study's primary research question and the five primary sub-questions of the study. / Doctor of Education / The purpose of this study was to describe the perceptions of the support and professional development (PD) activities for and needed by novice school administrators (NSAs) in southwestern Virginia.

Staff auditors often rely on team members as a source of information to determine the behaviors that are normal and acceptable. This may be one cause of the prevalence of audit quality reducing dysfunctional audit behaviors (DAB) within the profession. Social influence theory, applied in an auditing context, posits that staff auditors are influenced not only by the preferences of their superiors (i.e., compliance pressure) but also by their peers' DAB (i.e., conformity pressure). Given the importance of the work performed by staff auditors, I conduct an experiment to identify the role that a peer team member's behavior and a superior's preference plays in influencing staff auditors' behavior. I predict, and find, that staff auditors with a peer team member who engages in a DAB are more likely to engage in a DAB. I also predict, and find, that staff auditors with a superior who has a preference toward efficiency are more likely to engage in a DAB. Finally, I predict that a superior's preference toward efficiency will amplify the influence of a peer team member's involvement in a DAB. Interestingly, I find that a superior's preference amplifies the effect of a peer team member's behavior when it is toward efficiency only, not effectiveness, for a face-to-face request from the client, but not for an email request. These results suggest that peer behavior influences the effect of a superior's preference of staff auditors in the intimidating situation of having a face-to-face interaction with the client. This could be because of the cognitive dissonance staff auditors experience when their general understanding of the standards does not align with their peer's behavior. The results of this study provide insights into a potential risk introduced to the audit engagement through audit team dynamics. / Doctor of Philosophy / Financial statement audits conducted by public accounting firms are frequently performed in a team setting. Most of the audit team consists of younger, inexperienced staff auditors who perform much of the testwork that informs the final audit opinion. Staff auditors’ lack of knowledge requires them to seek information to complete their testwork, from both their peer team members and their superiors. Peer team members may engage in behaviors that reduce the quality of the audit, which shows staff auditors that these dysfunctional behaviors are acceptable. At the same time, superiors often display a preference toward effectiveness (i.e., improving audit quality) or efficiency (i.e., saving time). I perform an experiment to determine if staff auditors mimic the audit quality reducing behaviors of their peer team members, while also considering the preference of their superior. I find that staff auditors are more likely to engage in audit quality decreasing behaviors when their peer team members have done so previously. I also find that staff auditors are more likely to engage in audit quality decreasing behaviors when their superior has a preference toward efficiency. I find that a superior’s preference toward efficiency, but not effectiveness, amplifies the effect that a peer team member’s behavior has on the likelihood that a staff auditor engages in an audit quality increasing behavior of requesting information from the client in a face-to-face interaction, but not for an email request. These results suggest that peer behavior influences the effect of a superior’s preference of staff auditors in the intimidating situation of having a face-to-face interaction with the client. In general, I find that peer behavior and superior preference influence staff auditors’ chosen behaviors.

A perceived discrepancy exists in understanding between nursing educators' and hospital nurse leaders' views on job performance expectations and the reality of current job performance that may contribute to the difficulty experienced by novice nurses during their transition period. Lack of clarity in expectations may lead novice nurses to change jobs or leave the nursing profession within the first year of practice. The purpose of this descriptive study, guided by Benner's novice to expert theory, was to determine whether a difference exists between hospital nurse leaders' beliefs and nursing educators' beliefs about the frequency and competency levels, including leadership for novice nurses transitioning into practice, critical care nursing performance, teaching and collaboration, ability to plan and evaluate, interpersonal relations and communications, and professional development. Survey data were collected from 52 nursing educators and 52 hospital nurse leaders using the Schwirian's 6-dimension scale of nursing performance and analyzed using MANOVA and independent t tests. No differences were identified between hospital nurse leaders' and nurse educators' beliefs on the frequency and competency level in all areas examined for novice nurses transitioning into practice. Hospital nurse leaders' and nurse educators' expectations for novice nurses aligned. Further research should focus on ways to strengthen novice nurses' knowledge, critical thinking, and skills so they are better prepared to enter the transition period. Outcomes from this study may be used to improve education and transition to practice for novice nurses, which can result in positive social change.

Instructional scaffolding is a powerful tool that many teachers utilize to meet the challenge of individualizing instruction for diverse learners. The concept of instructional scaffolding is complex (Meyer, 1993), in that teachers have to determine what, how much, and what kind of help to give to students in a moment’s notice (Rodgers, 2004/05). Gaining expertise with scaffolding can take years, which leads us to worry about the effectiveness of novice teachers. A scarcity of research examining how to support a teacher’s development of instructional decisions such as scaffolding is reported (Anders, Hoffman, & Duffy, 2000). The ability to make scaffolding decisions requires teachers to be cognitively flexible, drawing from multiple domains of understanding to meet the individual needs of a group of students. However, little is known about which domains and understandings teachers draw on during scaffolding events or the rationales underlying this decision-making process. This naturalistic study examined the decision-making processes of a novice elementary ESOL teacher as she scaffolded instruction for her third-grade students. As she videotaped what she considered to be a successful scaffolding event each week, we unpacked the event together using the lens of Cognitive Flexibility Theory (CFT). The guiding questions were: (1) How can the decision-making processes underlying a novice ESOL teacher’s instructional scaffolding be described? (2) How can the lens of Cognitive Flexibility Theory inform a novice ESOL teacher’s scaffolding decisions? Data sources included interviews, field notes, and reflections of the sessions. Constant comparative analysis (Glaser & Strauss, 1967; Miles & Huberman, 1994) was used to analyze data. Rigor was demonstrated by establishing credibility, transferability, dependability, and confirmability (Lincoln and Guba). A grounded theory model of a kaleidoscope was created to describe the novice ESOL teacher’s decision-making processes during scaffolding events. The participant’s decisions were influenced by a variety of pedagogical and contextual domains while also being impacted by her views on scaffolding, on assessment, and on the connection between theory and practice. The participant’s conceptions of scaffolding became more complex and her confidence and sense of agency became stronger as a result of mentoring underpinned by CFT.

Comment s'approprie-t-on les règles de métier lors de l'année de stage de titularisation des enseignants débutants ? La conception traditionnelle de l'enseignement donne un rôle crucial aux experts et porte l'attention sur la place des collectifs professionnels dans le développement de l'activité des enseignants en formation. La sociologie a-t-elle à dire ou à redire face à cette approche ? Fruit d'une enquête de terrain sur trois établissements scolaires, nos résultats montrent que la relation dyadique classique, tuteur expert / novice, ne permet pas toujours aux novices de s'approprier les règles de métier. Cette configuration dyadique ne favorise pas le jeu de l'argumentation et de la contre-argumentation permettant via des accords ou des désaccords, l'apprentissage des règles. Ne conviendrait-il pas mieux d'introduire un tiers pour dépasser les freins statutaires qui brident la relation ? C'est ce que nous avons choisi de faire à partir d'une démarche expérimentale qui repose sur la mise en place d'une relation triadique. Le tiers élève le niveau de la contrainte de justification, et les conseils du tuteur ne peuvent plus s'appuyer uniquement sur l'avantage statutaire dont il bénéficiait jusqu'alors. Ce dispositif permet au stagiaire, au risque du conflit, engageant la nécessité d'opération de relativisation et de compromis, d'accéder aux règles enseignées par le tuteur, restées jusque-là inaccessibles. / How do the rules are appropriated during the year of preservice teachers? The traditional conception of education gives a crucial role to the experts and focuses on the place of professional collectives in the development of the activity of teachers in training. Does sociology have to say or complain about this approach? The result of our survey based of three schools, show that the classical dyadic relationship expert-tutor / novice does not always allow novices to appropriate the rules of trade. This dyadic configuration does not favor the game of argumentation and counter-argumentation through agreements or disagreements and get difficult the learning of rules. Would not it be better to introduce a third party to overcome the statutory obstacles breaking the relationship. This is what we choose to do from an experimental approach based on the establishment of a triadic relationship. The third party raises the level of the justifying constraint and the tutor's advice can no longer rely solely on the statutory advantage he enjoyed hitherto.

Science education reform in the United States has been slow to reduce the troubling science achievement gap between students from mainstream and non- mainstream backgrounds. Recent data suggest the gap persists in spite of improved attention to the multicultural education of teachers, and in spite of recent, more culturally inclusive and responsive curricular materials and instructional recommendations.In this study, I examine the cases of two European American male novice science teachers in middle schools with highly diverse populations, exploring their perceptions of the necessity of adapting their instructional approaches and the science curricula in order to meet the needs of their predominantly Native American, Mexican American, and African American students. Two theoretical frameworks inform this study, Rodriguez's (2005) sociotransformative constructivism, and Freire's critical pedagogy.I apply a qualitative case study method, to better understand and analyze the classroom setting and power relations of the context. Data consist of semi-structured interviews with each teacher, classroom observation and other field notes, the science curricular and instructional materials, and teachers' lesson plans.Each teacher acknowledged the ethnicities of students positively and noticed distinctive ethnocultural features (e.g., quinceañeras, Mexican Americans). Yet, their teaching approaches were primarily teacher-centric and monocultural. Each followed the book, usually lecturing, and striving dutifully to "cover" the topics. They did not solicit students' knowledge or engage them in dialog to explore their thinking. Even when the curriculum guide detailed relevant science knowledge students of some culturalgroups might have, both teachers declined to use it. These well-meaning teachers did not fully perceive that students whose culturewas different from their own might have different and relevant knowledge, experiences, or histories which were resources for learning. As a result, even when the teachers tried more student- centered, inclusive strategies, such as implementing authentic science activities, they did not support students' construction of knowledge through responsive dialog.Teachers assigned to ethnically and culturally diverse students must be helped to fully understand that learners from other cultures have differing knowledge resources. Science teachers in particular must recognize the social and ideological landscape in which their teaching take place.

Des recherches récentes (Boies, 2012; Chong et Low, 2011; Riopel, 2006; Vallerand, 2008) ont démontré que les difficultés vécues par les enseignants lors de l’insertion professionnelle sont liées à la fragilité de leur identité professionnelle. Toutefois, peu de recherches ont étudié la construction identitaire des enseignants novices au cours de la première année d’insertion, ce que cette recherche exploratoire entend faire. Afin d’appréhender le processus dans son instantanéité, six enseignants novices du secondaire, cinq femmes et un homme, ont été suivis tout au long de leur première année d’insertion. Des données qualitatives ont été recueillies à l’aide de journaux de moments (Hess, 2006) tenus régulièrement ainsi qu'une entrevue semi-dirigée en début de première année. Nos résultats décrivent l’interaction entre les différentes sous-identités des novices (Day et Kington, 2008) constitutives de leur construction identitaire en proposant trois constats, c'est-à-dire l'unicité, la nécessité et la dualité des trois sous-identités au sein de l'articulation identitaire. Cette recherche contribue à une meilleure compréhension de l’expérience de la première année d’insertion et permet de proposer des améliorations à la formation initiale ainsi qu’aux mesures de soutien à l’insertion.

Magister Scientiae (Occupational Therapy) - MSc(OT) / Professional socialisation is a key dimension within the professional development of an occupational therapy practitioner. Professional socialisation in the first year of practice involves a process of change within the individual with regards to knowledge, skills and reasoning. The process further involves the novice’s developmental induction into the culture of the profession and into the practice context. Novice practitioners who are not appropriately supported in their professional socialisation process may become demoralised as practitioners. It is necessary to explore professional socialisation from the perspectives of novice occupational therapy practitioners themselves, in order to generate an understanding of how professional socialisation can be supported in the first year of practice. This is of vital importance otherwise the profession may run the risk of attrition. Therefore, the aim of this study was to explore and describe novice occupational therapists’ perceptions and experiences regarding professional socialisation during the first year of practice. A qualitative research approach and exploratory descriptive research design was utilised in the public health system in South Africa. Purposive sampling was utilised to select nine participants for the study. Data collection methods included two semi-structured interviews and a dyad interview discussion which were audio-recorded, transcribed verbatim and analysed through thematic data analysis. The strategies of member checking, peer review, reflexivity, and an audit trail ensured trustworthiness of the study. Ethics clearance was obtained from the UWC Research Committee. Three themes originated from the findings of this study. The first theme, stepping into the unknown, illustrates a dissonance between the participants’ expectations for practice and the actual realities of practice that they encountered. The second theme, uncovering the occupational therapy culture, highlights power dynamics and inconsistencies within the profession as perceived by the participants. The third theme, becoming a professional, highlights how the participants responded to the challenge of transitioning from student to professional and started to internalise their professional identity. Recommendations to support the professional socialisation of novice therapists in the South African context are made in respect of occupational therapy education, continued professional development, support for novice therapists, transformation in the profession and future research.

Thesis advisor: Lauri Johnson / This qualitative case study examined the influence of the processes of supervision and evaluation on the job satisfaction of novice teachers in one suburban Massachusetts school district. The conceptual framework guiding this research was the “Three Factor Theory” developed by Dinham and Scott (1998) which emphasizes the role of school-based factors on job satisfaction. The data collection included interviews with novice teachers, school leaders and central office leaders. A document review was also conducted. The results of this study found that supervision and feedback that was specific and timely, provided from a coaching standpoint was perceived to be an important factor influencing job satisfaction. Building leaders felt that evaluation, through the self-reflection and goal setting process, also positively contributed to the job satisfaction of novice teachers, however, novice teachers did not confirm this finding. Recommendations include additional professional development for both building leaders and novice teachers that focuses on the use of supervision and feedback to inform the evaluation process, including the self-reflection and goal setting stages. / Thesis (EdD) — Boston College, 2016. / Submitted to: Boston College.
