Despite reform efforts to broaden historically underrepresented populations across STEM disciplines, the data continues to highlight gaps of achievement across racial demographics. In an effort to address educational inequity, current reform efforts have touted the implementation of learning progressions as a promising strategy that can produce equality of outcomes across racial groups in STEM. Despite this promising effort, few studies have examined how to integrate practices of equity within learning progressions for groups such as African Americans that have been traditionally excluded from science and STEM. This study argues that an equity oriented learning progression should be responsive to sociohistorical factors of epistemic injustice that dissociated African Americans identities from being producers of knowledge. This study argues that the construction of a learning progression to advance the epistemic participation of African American students is aligned with goals of social justice related to diversifying STEM. The aims of this study explored how African American students progressed toward epistemic agency as STEM learners as a result of identity transformation through the engagement of the epistemic practices of engineering. This study used qualitative methodology to explore how student participants demonstrate epistemic development in their artifacts and discourse when engaging in engineering activities across a learning progression designed to develop epistemic agency. The findings from this study contribute to a broader understanding of how equity-oriented learning progressions can be designed to promote epistemic justice, how sociocultural positionings influence epistemic communities, and how students can become epistemic agents to raise STEM awareness within their local community. Advancing students epistemic practices of engineering and epistemic agency as STEM learners is key to creating meaningful pathways into STEM for students in K-12. / Doctor of Philosophy / National imperatives to broaden the STEM participation of underrepresented groups remains a prominent priority across educational research. Due to marginal effectiveness associated with racialized minorities, researchers continue to explore equity oriented initiatives. In an effort to address educational inequity, current reform efforts have touted the implementation of learning progressions as a promising strategy that can produce equality of outcomes across racial groups in science and STEM. Educational inequity prevents underrepresented populations, such as African Americans, from having the types of educational experiences that position them as significant contributors in STEM and more specifically engineering. This study argues that the construction of a learning progression to advance the epistemic participation and agency of African American students in STEM is a sociohistorical response to a legacy of epistemic injustice. Qualitative methodology was used to explore how African American students progressed toward epistemic agency as STEM learners as a result of identity transformation through the engagement of the epistemic practices of engineering. The findings indicated that the engineering design activities within the curriculum positively influenced students' identity, self-efficacy, and demonstration of epistemic agency across the learning progression. Additionally, the findings indicated the effectiveness of using the epistemic practices of engineering to facilitate the cognitive development of the engineering habits of mind. Lastly, the findings indicated the significance of using the epistemic practices of engineering to reposition African American students' identities as epistemic contributors both within the classroom and within their local community.

Every time we act in an effort to attain our epistemic goals, we express our epistemic agency. The present study argues that a proper understanding of the actions and goals relevant to expressions of such agency can be used to make ameliorative recommendations about how the ways in which we actually express our agency can be brought in line with how we should express our agency. More specifically, it is argued that the actions relevant to such expressions should be identified with the variety of actions characteristic of inquiry; that contrary to what has been maintained by recent pluralists about epistemic value, the only goal relevant to inquiry is that of forming true belief; and that our dual tendency for bias and overconfidence gives us reason to implement epistemically paternalistic practices that constrain our freedom to exercise agency in substantial ways. For example, we are often better off by gathering only a very limited amount of information, having our selection of methods be greatly restricted, and spending our time less on reflecting than on simply reading off the output of a simple algorithm. In other words, when it comes to our freedom to express epistemic agency, more is not always better. In fact, less is often so much more.

Stereotype threat is a psychological phenomenon that occurs when individuals become aware that their behavior could potentially confirm a negative stereotype. Though stereotype threat is a widely studied phenomenon in social psychology, there has been relatively little scholarship on it in philosophy, despite its relevance to issues such as implicit cognition, epistemic injustice, and diversity in philosophy. However, most psychological research on stereotype threat discusses the phenomenon by using an overly narrow picture of it, which focuses on one of its effects: the ability to hinder performance. As a result, almost all philosophical work on stereotype threat is solely focused on issues of performance too. Social psychologists know that stereotype threat has additional effects, such as negatively impacting individuals’ motivation, interests, long-term health, and even their sense of self, but these other effects are often downplayed, or even forgotten about. Therefore, the “standard picture” of stereotype threat needs to be expanded, in order to better understand the theoretical aspects of the phenomenon, and to develop broader, more effective interventions. This dissertation develops such an “expanded picture” of stereotype threat, which emphasizes how the phenomenon can negatively impact both self-identity and epistemic agency. In doing so, I explore the nature of stereotypes more generally and argue that they undermine groups’ moral status and contribute to what is called “ontic injustice.” I also show how stereotype threat harms members of socially subordinated groups by way of coercing their self-identity and undermining their epistemic agency, which I argue is a form of epistemic injustice. Lastly, I analyze the expanded picture’s implications for addressing the low proportion of women in professional philosophy. I critically engage recent arguments that these low numbers simply reflect different interests women have, which if innate or benign, would require no intervention. My expanded picture shows the mistakes in this sort of reasoning, which is also present in discussions on the underrepresentation of women in science. The expanded picture of stereotype threat that this dissertation develops is not only practically important, but also advances key philosophical debates in social epistemology, applied ethics, and social metaphysics.

This dissertation consists in a defence of the claim that belief is a state on which its bearer can reflect only deliberatively. That partial characterization of the concept is intended to throw light on the status of belief as a rational phenomenon. I defend it by appeal to features of our actual and imagined practices of ascribing belief linguistically, both to others and ourselves. Having set out the characterization in the first of four chapters, in the second chapter I survey the ways of learning from words: evidentially, by report, and by belief-expression. I go on to propose that where a person’s words afford belief of his belief, they do so through the belief-expressive character of assertoric speech. In the third chapter, I defend that claim as it applies to the case of ascribing belief to another. I argue that my characterization best explains the fact that we do not ordinarily report our beliefs or invite others to do so. I explain our ordinarily ascribing belief from the expressive character of assertoric speech by appeal to the relation between assertion and belief. In the fourth chapter, I turn to the prospect of ascribing oneself belief based on one’s own words. I argue that self-ascribing belief through the expressive character of words is alone consistent with the self-ascriber’s basic psychological and linguistic integrity. I recommend my characterization of belief for its capacity to explain the disintegrating effects of self-ascribing belief by one’s own report. I again appeal to the relation between assertoric speech and belief to explain the feasibility of self-ascribing belief through the expressive character of one’s words.

This thesis investigates the potential for Knowledge Building in large size Pharmacy classrooms. Knowledge Building is the social creation and continual improvement of ideas (Scardamalia & Bereiter, 2003). The pedagogy and technology that underlie it are based on a complex system involving 12 interdependent principles. This research examines principle-based classroom designs, targeting two Knowledge Building principles--epistemic agency and collective responsibility for community knowledge. Successive design changes were implemented to a self-care course for undergraduate Pharmacy students (n = 182), using case study methodology. The goal underlying design changes was to develop a more dynamic classroom environment involving all students and empowering them to take charge of knowledge advancement at high cognitive levels, through assuming greater agency and collective responsibility for their knowledge advances. Design features that were incorporated into class procedures included class panels to discuss cases, student-generated self-assessment examination questions, and online discussion views in a virtual learning community, Knowledge Forum. Surveys, student comments, self-assessments, field notes, online discourse and course exam scores were used to determine effects of principle-based design changes. Results, taken as a whole, indicate that each new design feature contributed to advances with no negative effects uncovered. Raters blind to authorship of student- versus instructor-generated exam questions could not distinguish between them. Analysis of student commentary indicated advances in line with the broad network of Knowledge Building principles, as well as those specifically targeted in design improvements. Advances in performance on exams, surveys, and in student discourse further contributed to the overall picture of positive effects. Design strategies appropriate for large classroom implementation are shown to facilitate a shift from learning as an exclusively individual enterprise, to the creation of a Knowledge Building Community with students assuming levels of responsibility and agency normally assumed by the teacher.
