Instructional Strategies For High School Ell Refugee Students In Mathematics, Seoyeon Lee Aug 2017

Instructional Strategies For High School Ell Refugee Students In Mathematics, Seoyeon Lee

Boise State University Theses and Dissertations

This study investigates instructional strategies used in high school mathematics classrooms to learn the way teachers modify their lessons to teach late-entry ELL students, including refugees with little or no formal education. Two separate ELL classes, two mainstream classes with mixed groups of ELL students and monolinguistic students, and one mainstream class without late-entry ELL students are observed for this study. Both qualitative analysis regarding teaching English language while using mathematics content, specifically vocabulary acquisition, and quantitative analysis as to how teachers spend their instructional time are used to present the findings of this study. The findings provide a forum ...


Investigating College Instructors’ Methods Of Differentiation And Derivatives In Calculus Classes, Wedad Mubaraki Mar 2017

Investigating College Instructors’ Methods Of Differentiation And Derivatives In Calculus Classes, Wedad Mubaraki

Boise State University Theses and Dissertations

This case study investigates three college instructors’ instructional approaches and their mathematical discourses in the context of calculus (e.g., concepts of limit and derivatives). The analyses focus on ways in which instructors communicate limit and derivative concepts that are observed in the classrooms, using Sfard’s discursive framework (a communicational approach). In particular, instructors’ use of mathematical words while introducing derivative and limit concepts are analyzed, as well as instructors’ ways of using visual mediators such as symbols, numbers, expressions, and graphs are investigated. The findings of the study indicate instructors’ different instructional approaches and differences in their mathematics ...
