Supporting Representation-Rich Problem-Solving In High School Physics, Lyrica L. Lucas
Supporting Representation-Rich Problem-Solving In High School Physics, Lyrica L. Lucas
Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research
The literature on physics education research (PER) promotes the use of multiple representations (such as pictures, diagrams, written explanations, and mathematical expressions) to enhance the problem-solving ability of students through instruction. The purpose of this study was to explore the use of a scaffolding strategy that involved the use of multiple representation tasks in problem-solving in a modeling physics class in high school. Another class with similar background was selected as a comparison group. In 12 in-depth problem-solving interviews of students drawn from the two classes, I investigated in detail how the students responded to the multiple representations tasks and …
Planning And Enacting Mathematical Tasks Of High Cognitive Demand In The Primary Classroom, Kelly Georgius
Planning And Enacting Mathematical Tasks Of High Cognitive Demand In The Primary Classroom, Kelly Georgius
Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research
This study offers an examination of two primary-grades teachers as they learn to transfer knowledge from professional development into their classrooms. I engaged in planning sessions with each teacher to help plan tasks of high cognitive demand, including anticipating and planning for classroom discourse that would occur around the task. A detailed description of the planning and teaching that took place during the study provides information about how a teacher can learn and what a teacher learns to consider in order to plan and implement meaningful mathematical lessons. This design experiment describes the work of two teachers who participated in …
