We live in a scientific society. Science is all around us. We take scientific principles for granted every time we use technology, such as a car, a computer, or a cell phone. Paradoxically, the scientific literacy of the population is minimal at best. Having a basic knowledge of scientific principles is no longer a luxury but, in today's complex world, a necessity. To increase the scientific literacy of non-science majors, an astrobiology course was developed at the Center for Science and Mathematics Education at The University of Texas at Austin. The course subscribes to an educational philosophy that promotes the significance of teaching science to non-science majors, endorses the importance of multidisciplinary content knowledge, supports the teaching of the nature of science in an implicitly mode, advances the discussion of socio-scientific issues, and includes competent thinking-based teaching strategies using the dynamic discipline of astrobiology. The thesis reviews the problems in scientific literacy, outlines the characteristics of this innovative course, proposes a novel standard - competent thinking - to evaluate scientific literacy and analyzes the results of this course in terms of competent thinking. Data collected provided evidence of an increase of competent thinking skills among the students, especially in terms of self-reflection. Both the first and the second pilot study showed strong evidence that students transitioned from naive to competent thinking arguments. The main study demonstrated that students greatly improve their self-reflecting skills. The final study confirmed improvement in terms of self-reflecting skills, and showed that students gradually improve their arguments based on logic, reason, sophistication, and evidences. Therefore, the results show that this innovative astrobiology course is an effective tool for enhancing competent thinking skills among non-science major students. / text

Karl Popper developed a falsificationist epistemology in which knowledge grows through falsifying, or criticizing, our theories. Since criticism plays such a vital role in Popper’s falsificationist methodology, it seems natural to envisage his heuristic as a helpful resource for developing critical thinking. However, there is much controversy in the literature over the feasibility and utility of his falsificationism as a heuristic. This study argued that Popper’s falsificationism is justified on the grounds that it not only solves, theoretically, the problem of the bounds of reason in the form of comprehensively critical rationalism, but influences, practically, the research work of scientists from diverse fields. It also found that there is cause for cautious optimism about the effectiveness of falsification as a strategy for solving scientific problems. Popper’s falsificationist epistemology carries profound political and educational implications. On a political level, it is necessary to establish and maintain an open society by fostering five core values, viz. freedom, tolerance, respect, rationalism, and equalitarianism, as well as three crucial practices, viz. democracy, state interventionism, and piecemeal social engineering. On an educational level, the overriding aim is to nurture in children the requisite abilities, skills, and dispositions characteristic of critical thinking for full participation in an open democratic society. In order to achieve Popper’s educational ideal, this study proposed implementing Matthew Lipman’s Philosophy for Children (commonly known as P4C) programme in schools, arguing that the programme can fulfil the requirements of Popper’s educational ideal through using community of inquiry as methodology of teaching, philosophy as subject matter for inquiry, logic as both means and ends of inquiry, and Socrates as a model teacher for inquiry. The present study then conducted an experiment to assess the effectiveness of Lipman’s P4C programme in promoting Hong Kong children’s critical thinking. Forty-two Secondary 1 students volunteered for the experiment, from whom 28 students were randomly selected and randomly assigned to two groups of 14 each: one receiving P4C lessons and the other receiving English lessons. The students who were taught P4C were found to perform better in the reasoning test than those who were not, to be capable of discussing philosophical problems in a competent way, and to have a very positive attitude towards doing philosophy in the classroom. It was also found that P4C played a major role in developing the students’ critical thinking. Considering that the construction of children by adults as incompetent in the sense of lacking reason, maturity, or independence reinforces the traditional structure of adult authority over children in society, it runs counter to the goal of fostering critical thinking in children. As a way to return justice to childhood and to effectively promote critical thinking in children, the present study suggested reconstructing the concept of childhood, highlighting the importance of establishing a coherent public policy on promotion of agency in children and also the importance of empowering them to participate actively in research, legal, and educational institutions. / published_or_final_version / Education / Doctoral / Doctor of Philosophy

The study explores perceptions of critical thinking and knowledge by New Senior Secondary Liberal Studies teachers in Hong Kong. The insights in this study have implications for the curriculum development and pedagogy, particularly regarding how we can improve the teachers training of critical thinking. Seven Liberal Studies teachers (with various levels of teaching experience and differing backgrounds) were invited to in-depth interviews about their experience teaching Liberal Studies, and particularly regarding critical thinking and knowledge, as well as their pedagogies and views of this subject. Factors such as work experience, personality, school training, and cultural identity affect ways of seeing ‘critical thinking’ and ‘knowledge’. Also, these interviews provide insights into a better pedagogy in high order thinking. We can gain understanding of the difficulties and constraints of teaching critical thinking in Liberal Studies. The research is also a critical thinking process, which is explored in conversations with participants. The study asked them to reflect on what they thought and had experienced. The participants gave useful insights and suggestions. / published_or_final_version / Education / Master / Master of Education

Social work practice requires that graduates be prepared to deal with complex, multifaceted problems which cannot be defined completely, do not have absolute, correct answers and can be approached from multiple perspectives. This study evaluated the influence of case-based instruction on MSW students' reflective judgment, an aspect of critical thinking associated with the ability to reason through ill-structured problems. (King, Wood, & Mines, 1990). The Reflective Judgment Model, which describes a developmental continuum based upon epistemic assumptions regarding the source and justification of knowledge claims, served as the theoretical framework for the assessment of reflective thinking in this mixed methods study. A quasi-experimental pre-post nonequivalent control group design was utilized to explore whether students who participated in a case method course demonstrated greater increases in reflective judgment than those who did not. MSW students enrolled in a case-based capstone course at a major metropolitan university in the southeast served as the intervention group, while foundation year students enrolled in a research methodology course served as the comparison group. Both groups completed the Reasoning about Current Issues Test (RCI), which is an online, standardized measure that has been widely used to assess reflective judgment (Wood, Kitchener, & Jensen, 2002) at pre and posttest. Content analysis procedures were used to facilitate assessment of students' initial and final case analysis papers for evidence of changes in the reflective thinking skills and problem-solving approaches utilized on initial and final case analysis papers. The case method participants' mean RCI scores remained unchanged between pre and posttest, while RCI posttest scores of participants in the control group decreased significantly. Pre and posttest comparison of students' case analysis papers using a customized rubric based on Wolcott's Steps for Better Thinking (2006) similarly indicated no mean changes in problem-solving approaches between pre and posttest. However, students who began the course using strategies associated with pre-reflective judgment increased their scores on the rubric significantly while those who exhibited higher levels of quasi-reflective judgment at pretest decreased at posttest. Strategies for designing a developmental curriculum to target the reflective judgment levels of MSW students are proposed.

This dissertation formulates and describes a type of thinking called critical-reflective thinking. Examples of critical-reflective thinking appear in the works of many major Western philosophical figures, including the main thinkers considered here, Plato, Martin Heidegger, Hannah Arendt, and Henry David Thoreau. Although this list of thinkers is eclectic, these philosophers come together in describing a common phenomenon, although they do not thematically designate or explain it. Their works illustrate a type of thinking in which people are invited by prompting events to consider their presuppositions—notions they have taken as true without prior consideration. I have deemed this phenomenon “critical-reflective thinking” to emphasize its dimensions of self-reflection and critical consideration. By exploring examples from the works of the authors listed above (among others, such as Ralph Waldo Emerson, Hans-Georg Gadamer, and Elaine Scarry), I formulate critical-reflective thinking as a specific phenomenon. In Chapter One, I formulate this important type of human thought by describing its occurrence, especially the invitation of the prompt and the disclosure and examination of presuppositions. In Chapter Two, this dissertation explicates the value of taking part in this type of thinking. Since critical-reflective thinking allows people to consider previously unreflective aspects of their understanding (i.e. presuppositions), by taking part in critical-reflective thinking, people stand to grow in self-awareness and become liberated to new possible ways of seeing the world and going about life. Given the value of such growth and liberation, it is important to explore how humans can develop the practice critical-reflective thinking. Chapter Three explores strategies for cultivating critical-reflective thinking. Plato, Heidegger, Arendt, and Thoreau suggest five such strategies: spending time in solitude, taking leisure, developing an open attitude, practicing wakeful attentiveness, and acquire virtues such as humility, courage, and fortitude. Formulating and exploring the phenomenon of critical-reflective thinking not only provides a theory of a type of thinking, but also describes an important aspect of human experience. This dissertation encourages readers to consider their own experiences of thinking. It also poses the challenge of leading a more examined life by critically-reflecting on notions we often take as given.
