Several small-scale experimental classroom studies Star and Rittle-Johnson demonstrate the value of comparison in mathematics learning: Students who learned by comparing and contrasting alternative solution methods made greater gains in conceptual knowledge, procedural knowledge, and flexibility than those who studied the same solution methods one at a time. This study will extend that prior work by developing, piloting, and then evaluating the impact of comparison on students' learning of mathematics in a full-year algebra course.
Phi Delta Kappa International is the premier professional association for educators. For more than 100 years, it has focused its work on the tenets of service, research, and leadership.
PDK is one of the largest education associations and has more than 35,000 members, including teachers, principals, superintendents, and higher education faculty and administrators. PDK publishes the highly-regarded Phi Delta Kappan, the No. 1 education policy magazine, and sponsors the annual PDK/Gallup Poll of the Public's Attitudes Toward the Public Schools.
Founded in 1943, ASCD (formerly the Association for Supervision and Curriculum Development) is an educational leadership organization dedicated to advancing best practices and policies for the success of each learner. Our 170,000 members in 136 countries are professional educators from all levels and subject areas––superintendents, supervisors, principals, teachers, professors of education, and school board members.
The Association for Science Teacher Education is a non-profit professional organization composed of over 800 members from countries across the globe. The mission of the ASTE is to promote excellence in science teacher education world-wide through scholarship and innovation. We are an international association of science teacher educators, scientists, science coordinators and supervisors, and informal science educators who prepare and provide professional development for teachers of science at all grade levels.
AMTE is the largest professional organization devoted to the improvement of mathematics teacher education—it includes over 1000 members devoted to the preservice education and professional development of K-12 teachers of mathematics.
How important is discourse in the mathematics classroom? Interest in this question has grown dramatically as mathematics education has recognized the role of communication in understanding. This book presents portraits of teaching by secondary school teachers who have closely observed classroom communication, conversation, and discourse and have sought to use them to improve the quality of their teaching and their students' learning.
NCTM Mission Statement
The National Council of Teachers of Mathematics is a public voice of mathematics education, supporting teachers to ensure equitable mathematics learning of the highest quality for all students through vision, leadership, professional development, and research.
