Epistemic Practices In Adults And Adolescents, Sarah Emlen Metz Jan 2017

Epistemic Practices In Adults And Adolescents, Sarah Emlen Metz

Publicly Accessible Penn Dissertations

Being epistemically responsible requires an appreciation for both the power and the limitations of human knowledge, forming and adjusting one’s beliefs in a way that is responsive to the right criteria. Epistemic responsibility is needed among the populace as well as the elite for a functional democracy. It is also crucial for the understanding of science. However, without clear, shared norms of how best to form, adjust, and justify beliefs, we cannot hold each other epistemically accountable. In this dissertation, I explore how adolescents and adults conceive of the best practices for forming beliefs. Chapter 1 asks what criteria ...


Supernova Cosmology And How To Talk About It: New Approaches To Cosmological Parameter Inference With Type Ia Supernovae And An Assessment Of The Education And Public Outreach Program Of The Dark Energy Survey, Rachel Cane Wolf Jan 2017

Supernova Cosmology And How To Talk About It: New Approaches To Cosmological Parameter Inference With Type Ia Supernovae And An Assessment Of The Education And Public Outreach Program Of The Dark Energy Survey, Rachel Cane Wolf

Publicly Accessible Penn Dissertations

The discovery of the accelerating expansion of the Universe launched a new chapter in modern cosmology. Evidence for this accelerating expansion was first observed using Type Ia supernovae, which are brilliant, standardizable explosions that can be detected at large distances and used to infer cosmological parameters. New surveys are being designed to detect thousands of Type Ia supernovae, ushering in an era where parameter inference is no longer limited by statistics, but by systematic uncertainties. One of these systematics which is not well understood is the progenitor and progenitor environment, which can be investigated by studying properties of the supernova ...


Making Waves: An Exploration In Learning Through Art, Science, And Making, Emma Jane Anderson Jan 2017

Making Waves: An Exploration In Learning Through Art, Science, And Making, Emma Jane Anderson

Publicly Accessible Penn Dissertations

For nearly one hundred years, from progressive education to critical pedagogy, philosophers, researchers, and educators have advocated for listening, respecting, and providing space for the learner’s voice within education. When teaching challenging science content, it is vital to provide both a context for the knowledge and a reason for learning the content. It can be difficult to provide a learning environment that allows learners to gain an understanding of demanding content while being able to have creative self-expression—agency—without turning youth culture into a static banal concept. This study aimed to tackle the challenge of providing context, a ...
