Both individual and whole class communication of students are described in this thesis, which is based on a clear gender perspective. Two articles describe the participation of boys and girls in communication with the whole class, the empirical data collected consisting of videotaped lessons. The extent to which boys and girls participate in the communication is reported in the first study, and in the second the extent to which boys and girls respond to the teacher's closed or open questions about science is presented. The third study reports boys' and girls' individual communication when responding to written science questions. The summary chapter ties the results together from the perspective of Positioning Theory, making the thesis a result of Mixed Methods Research. Results show that boys participate in whole class communication more often than girls, with approximately the same level of dominance as shown in research from the early 80s. Boys also answer more questions than girls, the differences becoming apparent when teachers ask closed questions that can be answered in one or two words. In isolation, girls answer written questions to the same extent as boys, but give longer responses containing a more developed scientific language. Results showing that boys position themselves as knowledgeable more often than girls when teachers ask closed questions, are explained from the perspective of Positioning Theory. Girls more often position themselves as knowledgeable when teachers ask open questions that require reflection. In test situations, with time for reflection, the boys and girls position themselves as knowledgeable students to the same extent. Teachers need to be aware of the positioning attempts created by teaching, and consequently take into account that different approaches in teaching provide boys and girls with different access to the communication space. / <p>Vid tidpunkten för disputationen var följande delarbete opublicerat: delarbete 3 accepterat.</p><p>At the time of the doctoral defence the following paper was unpublished: paper 3 accepted.</p>

Background: Radon is a high impact environmental pollutant and is the second leading cause of lung cancer in Canada. Despite the gravity of the health risk, residents have inadequate awareness and have taken minimum preventive actions. The success of any population-level health awareness program is contingent on the views and actions of key decision makers at the household level. People's perceptions of the risk should inform health communication messaging that aims to motivate them to take preventive measures. The objective of this study was to measure the quantifiable associations and predictions between perceptions of radon health risk and their preventive actions; to explore and examines the social determinants that enable and hinder the adoption of preventive measures. Additionally, the best effective radon control systems for both the new and existing houses and relevant policy implications have been examined. Methods: A mixed methods study consisting of surveys (n=557) and qualitative interviews (n=35) was conducted with both homeowners and tenants of Ottawa-Gatineau areas. Descriptive, correlation and regression analyses addressed the quantitative research questions. Thematic, inductive analysis identified themes in the qualitative data. A mixed methods analysis triangulate both results. A registered systematic review of radon interventions around the world was conducted and radon policy analysis was done by applying interdisciplinary frameworks. Results: Residents’ perceptions of radon health risk, smoking at home, social influence, and care for family significantly correlated with their intention to test for radon; the same variables predicted their protection behaviours. Residents obtained information on radon from the media, individual search, workplace and social networks. Residents who had dual - cognitive and emotional awareness of the risk, were motivated enough to take action. Having an understanding of the risk, caring for family, knowing others who contracted lung cancer and being financially capable were enablers for action. Obstacles included lack of awareness, cost of mitigation, lack of home ownership and potential stigma in selling the house. Residents attributed primary responsibility to public agencies for disseminating information and suggested incentivizing and mandating actions to promote preventive measures. Indoor radon is best controlled by installing an active SSDS with additional measures to seal any entry points in the foundation. The policy analysis generated a list of recommendations that can be implemented through multisectoral systems level actions to address the social determinants of risk distribution. Conclusions: Residents do not get the crucial information on radon health risk and report barriers in testing and engaging in protective action. Risk perceptions are subjective and influenced by micro and macro level factors. Inducing protective action to reduce risk requires comprehensive interventions taking into account dual perceptions of the threat. Future research can explore the dual aspects of risk perception and examine the contents of the risk communication message. Policy should address the shared responsibility of both governments and residents in tackling the issue with reasonable incentives and mandatory regulations.

Thesis advisor: Lillie R. Albert / Mathematics education is constantly at the forefront of public and academic debates during this era of increased accountability. Questions concerning teacher preparation and teaching practices that connect to pupil learning are central to these discussions. However, very few studies have examined relationships among these factors and most are confined to a short time period; thus, this dissertation studies such relationships over a two-year period. Informed by a sociocultural perspective, this study examines how preservice elementary teachers' past K-12 schooling and teacher education experiences influences their attitudes and perceptions about mathematics education over time. It also explores how teaching practices are shaped by these experiences, and are ultimately linked to pupil learning. A mixed-method design of survey and qualitative case-study research methods was employed to collect and analyze data over a two-year period. During the first year of this study, pre- and post-surveys using Likert-scale items were administered to all preservice teachers (n=75) enrolled in an elementary mathematics methods course. For a two-year period, the experiences of two participants were explored through longitudinal interviews, observations, and an examination of artifacts (i.e., teacher lesson plans, assessments, and pupil work) to develop in-depth case studies. Findings indicate that prior schooling experiences influenced teachers' initial attitudes and perceptions about mathematics. Nevertheless, over a short period, positive changes in teachers' attitudes and confidence to teach mathematics suggest that experiences in the mathematics methods course were conducive to building on teachers' prior knowledge. Survey and case-study findings also indicate that preservice teachers planned to teach mathematics with a reformed approach, which emphasizes a conceptual understanding of mathematic. However, it was challenging for case-study participants to implement a reformed approach as first-year teachers, especially if they had limited teaching models to reinforce this method. Findings also suggest that school context, classroom management, and mathematical content knowledge all influence teaching practices and pupil learning opportunities. Implications for teacher education, school reform, and future research are discussed. / Thesis (PhD) — Boston College, 2009. / Submitted to: Boston College.

Thesis advisor: Mary E. Walsh / The out-of-school factors that low-income children face can impact their wellbeing and ability to learn (Rothstein, 2010), leading to low academic performance, and, in turn, high levels of stress among their teachers. One of the numerous potential strategies that exist to address this problem is the implementation of systemic student support interventions, which are hypothesized to support teachers in addition to students (Ball & Anderson-Butcher, 2014). Using the City Connects intervention as an example of a comprehensive, systemic student support intervention that has demonstrated positive effects for students, this dissertation study examines the impact of this same intervention on teachers. The study used data obtained from annual surveys administered to all teachers in public schools (across several districts) where the City Connects intervention was implemented. The sample consisted of 656 responses from teachers in Boston Public Schools that were participating in the City Connects intervention during three designated school years (2012-13, 2013-14, and 2015-16). The study implemented a mixed-methods approach that allowed for an in-depth analysis of teachers’ perceptions of support from the City Connects intervention through both quantitative and qualitative data sources. Following exploratory and confirmatory factor analyses of the survey instrument itself, survey data was analyzed using the Validating Quantitative Data Model (Creswell & Plano Clark, 2007), in which quantitative findings were confirmed and expanded upon through analysis of data from a small number of open-ended survey questions. The results of this dissertation study support the continued use of systemic student support interventions in schools, as data confirm that teachers in schools with City Connects report being supported by the intervention. These results hold for veteran teachers who have been teaching for over sixteen years and have participated in the City Connects intervention for over ten years. Ultimately, the findings of this dissertation study suggest that, in addition to leading to positive changes in students’ developmental trajectories, student support interventions can improve the experiences of other members of the school community. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

Thesis advisor: David Scanlon / Classroom accommodations are a primary means of providing an appropriate education for students with disabilities. While there is value in student involvement in the accommodations process, the process continues to be teacher-driven, so we need to teach students to be strategic in selecting and utilizing their own accommodations. This problem holds true across disabilities, and students with visual impairments are no exception. The Student Self-Accommodation Strategy (SSA) was developed to support students with high-incidence disabilities in strategically selecting and utilizing their own accommodations. This study investigated SSA learning and performance for students with visual impairments and how learning the SSA impacted their classroom accommodation practices. The learning experiences of four students with visual impairments were compared using comparative case studies (Cresswell, Plano Clark, Gutmann, & Hanson, 2003) within a sequential explanatory design (Hanson, Creswell, Plano Clark, Petska, & Creswell, 2008). Mixed methods data were collected before, during, and after strategy instruction pertaining to accommodations knowledge and practices, strategy learning and performance, metacognition and self-regulated learning, and student perceptions of the SSA. Cross-case analysis revealed key findings regarding strategy instruction, strategy learning and performance, and metacognition and self-regulated learning. These key findings have implications for educating students with visual impairments and future research on the SSA. Ultimately, this study indicates that the SSA is a valuable tool for strategically selecting and utilizing accommodations; however, characteristics of individual students and their learning environments have a considerable impact on the development of strategic thinking. / Thesis (PhD) — Boston College, 2019. / Submitted to: Boston College.

This mixed-method study, grounded in critical pedagogy, explored teachers of the International Baccalaureate Diploma Program (IBDP) in Costa Rican public and private schools and examined the growth of the IB there. It surveyed the global mindedness of the teachers to understand their perceptions of the IB. The study also aimed to understand the IB’s Creativity, Activity, and Service (CAS) as a form of global education. Furthermore, neoliberalism was explored as a force driving the IB’s growth in Costa Rica. The study collected quantitative data from the Global Mindedness Scale (GMS) (Hett, 1993) from teachers of the IB in Costa Rica, assessing their level of global mindedness, factors that may have contributed to their score, and what differences, if any, existed between public and private school teachers. In the qualitative phase, four teachers were interviewed to explore how they perceived the IB in Costa Rica. It also critically analyzed the CAS requirement of the IB, as well as the neoliberal forces that have driven the growth of the IB in Costa Rica. The findings show that the type of school does not affect teachers’ global mindedness. Participants’ age and whether they have lived outside their country had a positive but weak relationship to teachers’ global mindedness. Teachers of STEM courses had slightly lower GMS scores. The interviews showed that teachers had positive perceptions of the IBDP and saw benefits for themselves, their students, and Costa Rica. The teachers were mostly uncritical in their responses, but the highest GMS scoring interviewee did express critical ideas. An analysis of the CAS requirement of the IB concluded that it reflects both soft and critical approaches to global citizenship education. Finally, the document analysis confirmed neoliberalism as a force behind the IB’s expansion in Costa Rica. Several recommendations were offered. First, an instrument is needed that can measure global mindedness on an international scale. Second, teacher education should incorporate issues related to global education. Third, implementation of the IBDP and other global education curricula requires ongoing support from policymakers, organizations, and schools. More research should examine the growth of the IB in other countries. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

This mixed methods study explored and measured the multi-dimensional construct of global-mindedness as it applies to the study abroad professional and defines the term study abroad professional. Hett’s (1993) Global-Mindedness Scale and the five dimensions of responsibility, cultural pluralism, efficacy, globalcentrism, and interconnectedness was utilized to determine the global-mindedness of study abroad professionals. Additionally, open and closed-ended questions were used to identify similarities across the study abroad professionals and to help define and give meaning to the term study abroad professional. Research findings lead to the identification of four themes. Theme one focused on characteristics that lend themselves to defining the term study abroad professionals. Theme two focused on the individual characteristics and their association with Hett’s five dimensions of global-mindedness. Qualitative data were used to support the various research questions whose answers became part of the working definition for a study abroad professional. Theme three focused on study abroad. And, theme four focused on evolving job announcements. International education, specifically study abroad, has become a specialized and recognized profession. What has emerged are specific academic requirements, professional training, and various professional and personal experiences being a requirement for entry into the field. Individuals entering the study abroad profession need to have an advanced degree, most likely in education or international/global studies (although other majors are acceptable), they will have studied, interned, volunteered, worked, or lived abroad, they will have good communication skills, be open-minded, organized, flexible, patient, empathetic, culturally sensitive, interculturally competent, and will have previous experience in the field. These findings have led to the definition of a study abroad professional. a study abroad professional is a globally-minded administrator or advisor with international and professional experiences, educational credentials, and personal traits that help them to relate to, communicate with, and support students, faculty, and staff, while fostering a safe study abroad environment that meets the needs of the institution and diverse student populations. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

Background: Practical training on hospital wards is a major component of basic nurse training. With this in mind, there were concerns with respect to the ability to provide nursing students with the quality of clinical experience that is required as a result of changes in the Barbados nursing policy to increase the number of students. Aim: The overall aim of this research was to understand student nurses’ clinical placement learning experience at the Queen Elizabeth Hospital in Barbados, based on their current and desired clinical experiences. Research objectives: (1) to examine the student nurses’ current learning experiences at the hospital; (2) to determine the student nurses’ desired experiences at the hospital; and, (3) to compare and contrast their current clinical experience with their desired experience by integrating the data across the quantitative and qualitative studies. Design: A sequential explanatory mixed methods research. Methods: First study: The Clinical Learning Environment Inventory (CLEI) (current and desired form) and the Clinical Learning Environment, Supervision and Nurse Teacher (CLES+T) questionnaires were distributed to second and third year student nurses (n = 191) at the Barbados Community College. Descriptive and inferential analysis performed. Second study: Qualitative semi-structured interviews (n = 10) among second and third year student nurses analysed thematically. Results: Quantitative survey (First study): ‘Student satisfaction’ (mean 25.74 of 35), ‘Task orientation’ (mean 25.62 of 35), the ‘Leadership style of the ward sister’ (mean 4.02 of 5) and ‘Premises of nursing care on the ward’ (mean 4.01 of 5) greatly informed students’ actual hospital experience. The current and desired hospital experiences were statistically significant different (z = 6.68 to 8.07, p = 0.000). Qualitative interviews (Second study): Four overarching themes were generated: ‘Engaged, proactive and communicative team’; ‘No cohesion among team’; ‘Students – willing to learn and motivated’; and, ‘Consequences – positive and negative’. Overarching findings from both studies: Four major topics describe the student nurses’ experiences: ‘Engagement of the ward nursing team’, ‘The nature of nursing care delivery’, ‘Clinical supervision and teaching of nursing students on the ward’, and ‘Nursing student satisfaction’. Conclusion: The ward sister influences the ward team spirit and students’ clinical learning, negatively or positively. Nurse educators should acknowledge the value of clear, well organised ward activities on students’ learning. Clinical nursing curricula should be based on a blended educational learning perspective.

Energy conservation can mitigate significant issues such as climate change and fuel poverty, yet the determinants of this behaviour are poorly understood. It is important to understand the antecedents of energy conservation in order to effectively stimulate this behaviour in society. Traditional models have focused on normative and intentional processes to explain environmental behaviour, but have proven largely unsuccessful for predicting energy use. Considering that day-to-day energy behaviour is likely to be habitual and context dependent, models such as the Comprehensive Action Determination Model (CADM, Klöckner & Blöbaum, 2010), which have integrated these factors with more traditional antecedents of behaviour, may better account for people’s actions. The early research in this thesis tests the application of this model to energy saving behaviour using a mixed-methods approach. Findings show that such a model is suitable to account for the drivers of energy behaviour, particularly because of the important role of habits and situational influences on this behaviour. Although this model can successfully predict daily energy behaviours that involve the routine curtailment of household energy use, one-off energy efficiency investment behaviours are unlikely to be determined by the variables considered by the CADM. That is, these behaviours may be more dependent on people’s understanding of the energy consumption in their household, or their energy literacy. Therefore, the second part of this thesis investigates the cognitive processes that inform conscious energy judgements to explore the antecedents of this energy literacy. The studies in this thesis uncover an unprecedented variety of energy judgement heuristics in this decision-making process, and these heuristics are further investigated, again using various methods. This thesis concludes that, to maximally facilitate energy conservation, the habitual and situational antecedents of energy saving behaviour, as captured in such frameworks as the CADM, need to be considered alongside the cognitive processes that shape people’s energy literacy when designing effective energy conservation interventions that target both routine and non-routine actions.
