How Does Student Understanding Of A Concept Change Throughout A Unit Of Instruction? Support Toward The Theory Of Learning Progressions, Brian Jay Dyer

Dissertations and Theses

This study documented the changes in understanding a class of eighth grade high school-level biology students experienced through a biology unit introducing genetics. Learning profiles for 55 students were created using concept maps and interviews as qualitative and quantitative instruments. The study provides additional support to the theory of learning progressions called for by experts in the field. The students' learning profiles were assessed to determine the alignment with a researcher-developed learning profile. The researcher-developed learning profile incorporated the learning progressions published in the Next Generation Science Standards, as well as current research in learning progressions for 5-10th grade students …

Impact Of Teachers' Planned Questions On Opportunities For Students To Reason Mathematically In Whole-Class Discussions Around Mathematical Problem-Solving Tasks, Sarah Elizabeth Enoch

Dissertations and Theses

While professional developers have been encouraging teachers to plan for discourse around problem solving tasks as a way to orchestrate mathematically productive discourse (Stein, Engle, Smith, & Hughes, 2008; Stein, Smith, Henningsen, & Silver, 2009) no research has been conducted explicitly examining the relationship between the plans that teachers make for orchestrating discourse around problem solving tasks and the outcomes of implementation of those plans. This research study is intended to open the door to research on planning for discourse around problem solving tasks.

This research study analyzes how 12 middle school mathematics teachers participating in the Mathematics Problem Solving …

Why Ask Why: An Exploration Of The Role Of Proof In The Mathematics Classroom, Joanna Rachel Bartlo

Dissertations and Theses

Although proof has long been viewed as a cornerstone of mathematical activity, incorporating the mathematical practice of proving into classrooms is not a simple matter. In this dissertation I aim to advance research on proof by addressing this issue. In particular, I explore the role proof might play in promoting the learning of mathematics in the classroom. I do this in a series of three articles (organized as three chapters), which are preceded by an introductory chapter. The introductory chapter situates the remaining chapters in the context of mathematics education research. In the second chapter I explore what the literature …
