In recent times the need for educational research dedicated to engineering education has been recognised. This PhD project is a contribution to the development of engineering education scholarship and the growing body of engineering education research. In this project it was recognised that problem solving is a central activity to engineering. However, it was also recognised that the conditions for doing engineering are changing, especially in light of pressing issues of poverty and environmental sustainability that humanity currently faces, and as a consequence, engineering education needs to emphasise problem definition to a greater extent. One mechanism for achieving this, which has been adopted by some engineering educators in recent years, is through courses that explicitly relate engineering to social justice. However, creating this relationship requires critical interdisciplinary thinking that is alien to most engineering students. In this dissertation it is suggested that for engineering students, and more generally, engineers, looking at their practice and profession through a social justice lens might be seen as a threshold that needs to be crossed. By studying the variation present among students in three different courses at three different North American universities, the intention was to understand how students approach and internalise social justice as a perspective on engineering and/or develop their abilities to think critically. A conceptual model to frame the study was developed by combining elements of threshold concept theory and the educational research methodology, phenomenographic variation theory. All three of the courses studied operated on a similar basic pedagogical model, however, the courses were framed differently, with social justice in the foreground or in the background with the focus on, in one case, ethics and in the other, sustainability. All courses studied appeared to be successful in encouraging engineering students to engage in critical thinking and a similar general trend in the development of students’ conceptions of social justice was observed in each of the three courses. However, it does appear that if one is interested in developing an articulated understanding of social justice, with respect to engineering, that an explicit focus on social justice is preferable. / Thesis (Ph.D, Chemical Engineering) -- Queen's University, 2010-04-07 13:12:29.207

This thesis examines what are for us two great sources or causes of error. The first arises from the influence of various cognitive biases upon our thinking, while the second emerges as a result of our wide-ranging dependence upon others for a vast amount of our beliefs about the world. Through both we can come to adopt false and harmful beliefs, a fact that naturally has both veridical and moral significance. One response is to suggest that we should increase our reliance upon experts in order to help us better acquire true beliefs and avoid false beliefs. By examining the historical, theoretical, psychological, and linguistic character of epistemic authorities and relationships, this avenue will be argued to be problematic. Scepticism in relation to epistemic authority is avoided in favour of an adoption of a critical attitude with respect to social sources of belief. The epistemology of testimony is next looked at, to see whether any lessons can be drawn from the nature of epistemic dependence to how we should epistemically approach others. Reductive versus non-reductive conceptions of the justification of testimony are explained, with the former conception being seen as naturally lending itself more to a critical treatment of social sources of belief. The question of why we should be rational at all is then examined. The positions of William K. Clifford and Karl Popper on the matter are explained, and my own views set forward. Finally, in light of the preceding groundwork, it is argued that there is a philosophical place and a social need for public education with respect to the broad epistemic situation in which we find ourselves.

Critical thinking skills have been identified as important for practicing nurses to acquire. Therefore, nurse educators have a responsibility to improve the critical thinking skills of nursing students. There is limited research related to critical thinking and nursing education especially in the clinical environment. Nurses need finely honed critical thinking skills in order to be safe, competent, and skillful practitioners of their profession.The purpose of this research was to study the way nursing faculty use clinical situations to develop critical thinking in student nurses. The research question was: How do nursing faculty use clinical situations to develop critical thinking in nursing students?In researching this question a grounded theory approach was chosen. The grounded theory approach allows for the development of theory or extension of existing theory which can be used to build on or base future research in nursing education (Chenitz & Swanson, 1986).Data collection was completed using open-ended interviews and participant observation which is consistent with the grounded theory approach. The constant comparative method of data analysis was used to compare and contrast data between and among identified groups.Clinical nursing instructors were asked to participate in the study. The subjects were interviewed and observed teaching in the clinical environment. Confidentiality was guaranteed through coding and destruction of the field notes upon completion of the project. Participation was voluntary and subjects could withdraw at any time from the study.There were no identifiable risks involved in the study. Potential benefits were increased awareness of strategies to develop critical thinking skills and contributions to improve nursing education.Setting the stage for critical thinking in nursing education was identified as the core category. The data supported the development of critical thinking in the clinical environment related to trusting relationships in a risk-free environment. Teaching strategies that contribute to the development of critical thinking were identified. Nursing faculty recognize the importance of critical thinking to nursing and attempt to instill critical thinking in the nursing students. / School of Nursing

Critical care nurses need finely honed critical thinking skills in order to be safe, competent, and skillful practitioners of their profession. If clinical nurses do not learn how to reason effectively, they may make inappropriate decisions about their patients' care, ultimately resulting in increased patient mortality (Fonteyn, 1991). In addition, increasing nurses' decision-making and autonomy has been shown to improve job satisfaction and retention (Prescott, 1986).There are many authors who write about the need for developing critical thinking skills among practicing professional nurses (Creighton, 1984; Jenkins, 1985; Levenstein, 1981, 1983, 1984). However, research assessing the impact of continued education and clinical experience on the development of critical thinking skills is sparse.The purpose of this exploratory study is to determine if there is a relationship between the level of critical thinking skills (as measured by the Watson-Glaser Critical Thinking Appraisal Tool, 1980) in critical care nurses and the length of nursing experience, amount of continuing education pursued annually, and the level of formal nursing education completed. The conceptual framework that provides the basis for this study is Patricia Benner's (1984) application of the Dreyfus Model of Skill Acquisition to clinical nursing practice.Participants (N = 61) were obtained on a voluntary basis from the population of critical care nurses working in the intensive Care Unit, Coronary Care Unit, Cardiac Catheterization Laboratory, or Emergency Care Center of a 600 bed midwestern acute care facility. Each participant in the study was asked to sign an informed consent agreeing to participate after receiving a written and oral explanation of the study. Confidentiality of the participants was maintained by substituting identification numbers for the subjects' names on the data collection instruments. The investigator supervised the administration of the critical thinking instrument and demographic questionnaire.The Pearson product-moment correlation coefficient and a two-tailed t-test for independent samples were used to determine if there were any significant relationships between the WGCTA score and the length of critical care experience, attendance of continuing education programs, or completion of additional formal education. This data analysis supported hypothesis one with the results revealing a significant positive correlation (r = .46, p = <.001) between the WGCTA scores and the length of critical care experience. In addition, a statistically significant but weak positive correlation was found between the WGCTA scores and the length of experience in CCU (r = .52, p = .001). No significant correlation existed between the WGCTA scores and length of experience in ECC, ICU, or CCL. Hypothesis two was supported with a significant difference (t = 3.58, df = 59, p = .001) found between the critical thinking ability of the two groups, with those who have completed an additional formal program of nursing education scoring higher. A significant but weak positive correlation (r = .30, p =.020) was found between the number of continuing education programs attended annually and the WGCTA scores. Multiple regression was performed with the total WGCTA score being the dependent variable and total critical care experience, completion of additional formal education, and attendance of continuing education programs being the independent variables. Only total critical care experience entered the equation (E = 16.03, p = <.001) explaining 21% of the variance.The information gained from this study will provide direction for the review of existing orientation, continuing education, and staff development programs provided at different levels of nursing experience and make suggestions for change to enhance critical thinking skill development. / School of Nursing

This qualitative research study investigated the expression of critical thinking in environmental subjects at university level in Australia. It also explored the strategies used by lecturers to encourage student critical thinking. Initially an open-ended questionnaire was sent to lecturers and tutors in universities across Australia and the responses from thirty participants were analysed thematically. From these participants semi-structured interviews were arranged with six lecturers and eight students from three different universities. The third phase of the research process involved analysing subject outlines and student assignments. Findings were triangulated to create a picture of the teaching and learning practices of critical thinking in this field. The three cases of Environmental Science, Environmental Engineering and Environmental Law were identified as having some common yet distinctively different themes in relation to critical thinking. In each discipline area three broad approaches to the expression of critical thinking were identified: scientific/technical, paradigmatic and reflective. The scientific/technical approach in science was most concerned with critique of experiments and studies, in engineering with problem solving and in law with the technical aspects of language and application of the law. The paradigmatic approach included critical analysis of the different theories, frameworks and paradigms of each subject. The reflective approach to critical thinking included students’ self evaluation of their learning within a specific subject. Notable differences between the three cases were the types of strategies used by lecturers to encourage student critical thinking. The Environmental Science lecturers were more inclined to use a wide variety of strategies, including provision of written material about critical thinking with critical thinking identified in marking criteria, discussion in class and guided exercises. The Environmental Engineering lecturers placed more emphasis on discussion in class than on providing written materials. The Environmental Law lecturers predominantly focused on the strategy of debating in class for the development of student critical thinking. The findings of this study are significant in providing support for the argument that development of critical thinking is subject specific rather than generic. This calls into question the use of generic skills testing for university graduates as a reliable measure of their ability to think critically in their field. The findings indicate that it is necessary for subject lecturers to be explicit with students about their expectations regarding critical thinking, particularly in relation to assessment. Findings suggest guidelines for lecturers including strategies and attitudes that encourage or hinder student critical thinking. Findings also suggest that the nature of the field of environmental and sustainability subjects lends itself to developing critical thinking, which is considered to be important.

It is a truism in contemporary understandings of semantics that there is no simple one-to-one correspondence between a word and its referent. As Wittgenstein has suggested, we can only know the meaning of a word by understanding the way it is used, and these uses are known often to be variable and highly context-dependent. / The issue of the variable meanings of terms is especially important when the term in question has assumed some centrality within a particular social domain, when its meanings are contested, and when the way the term is interpreted has a major bearing on subsequent social and institutional practices. In contemporary debates about the aims and purposes of higher education one such term is ‘critical thinking’. Whilst there is general unanimity in the higher education literature about the importance of ‘critical thinking’ as an educational ideal, there is surprisingly little agreement about what the term means exactly, as well as what exactly students should be taught in order to be appropriately critical in their field. / This thesis reports an empirical study which investigated conceptions of critical thinking as they are held by academics from a range of humanities disciplines: History, Philosophy, and Literary/Cultural Studies. The broad method used was a ‘textographic’ one, focusing both on how the concept of critical thinking was talked about by informants in interview, and also how it was constructed in a range of texts used by them in their teaching on undergraduate programs. / The study found a good deal of variation in the meaning of the term ‘critical’, not only between the three disciplines, but also within them. This variation was located in a number of areas: in the epistemic entities to which students needed to direct their thinking (e.g. textual vs. phenomenal entities), and in the various analytical modes they were required to adopt (e.g. evaluative vs. interpretative modes). The broad principle to be drawn from these findings is that the nature of one's thinking is indivisible from the object to which that thinking is directed. / The varieties of critical thinking found in the study provide some challenge to certain generic understandings of critical thinking, ones that have assumed increasing influence in higher education debates in recent years. The study concludes by suggesting that the teaching of critical thinking is likely to be more effective if handled within the context of students’ study in the disciplines, as opposed to a generic extra-disciplinary approach. It is also suggested that an important part of becoming a critical thinker in the academy is being able to recognise and to negotiate this variety of critical modes.
