Pathways Research
Pathways research has been funded by two NSF grants as well as ongoing support from curriculum adoptions. The Pathways program is built on decades of research on students’ mathematical learning, both in general and related to specific ideas proven critical for success in calculus and STEM fields. The Pathways research team has contributed novel research in areas such as quantitative and covariational reasoning, teacher change, professional development, curriculum development, scaling of curricular innovations, and many more.
Projects Pathways is based on two branches of mathematics education research. In recent decades, cognitive learning researchers have helped mathematics educators understand the ways in which students learn mathematical ideas as well as the implications of understanding key mathematical ideas in certain ways on future learning. Furthermore, researchers have made great strides in understanding the kinds of mathematical content knowledge for teaching that best supports effective instruction and how teachers interacting with a conceptually-oriented curriculum come to develop this special kind of content knowledge. The Pathways course materials, instructor supports, and professional development training models are all designed to leverage key findings in these research areas as well as to contribute to the growing body of literature by generating new insights about teaching and learning mathematics.
Pathways course materials are continuously revised and strengthened based on qualitative and quantitative research on student performance and have been in continual use for over 10 years in high schools and universities across the United States. Evidence suggests that students in Pathways courses are more successful than students using other curricula and are better prepared for Calculus.
Background Research
The Pathways program is built on decades of research related to general issues of students’ mathematical learning, understanding the ideas most critical for students’ success in calculus and STEM fields, and related to specific mathematical ideas such as rate of change, graphing, and algebraic reasoning.
