A Multiple-Case Study On The Impact Of An Introductory Real Analysis Course On Undergraduate Students' Understanding Of Function Continuity, Ryan Joseph Rogers Jan 2024

A Multiple-Case Study On The Impact Of An Introductory Real Analysis Course On Undergraduate Students' Understanding Of Function Continuity, Ryan Joseph Rogers

Theses and Dissertations--Mathematics

Undergraduate students' understanding of function continuity has not been explored broadly in previous research. The relevant findings in the literature are predominantly concerned with calculus students' understanding and misconceptions of continuity. Many of these misunderstandings are tied to the relationships which continuity has with limits and differentiability. This multiple-case study explores how, if at all, an introductory real analysis course impacts undergraduate students' understanding of function continuity and its connections to the notions of limits and differentiability. We embed our findings within the theoretical framework of Tall's three worlds of mathematics, namely, the embodied, symbolic, and formal worlds.

The cases …

Greta Thunberg (2021) By Maria Isabel Sanchez Vegara, Maughn Rollins Gregory

Picture Books

Greta Thunberg learned about climate change in school at the age of eight, when she persuaded her parents to make lifestyle changes to reduce their carbon footprint. At fifteen, after winning a writing competition about the environment, she came up with the idea of a school strike, inspired by student walkouts in the United States to protest legislative inaction on gun control. Though she couldn’t interest anyone else in the idea, her one-child strikes soon gained international attention. Greta’s story demonstrates some of the challenges and gifts that neurodiverse children bring to activism. This book also prods adults to think …
