Math Expressions from Houghton Mifflin Harcourt
In the fall of 2005, Houghton Mifflin Harcourt introduced Math Expressions into classrooms across the nation. Teachers, students, and supervisors quickly saw that by combining aspects of traditional approaches with the most powerful elements of reform teaching, Math Expressions developed deep conceptual understanding and fluency. And now, based on our experiences in these classrooms, Houghton Mifflin Harcourt is thrilled to provide the new Math Expressions © 2009 - the next generation of math programs.
Here's What Teachers Are Saying:
"With Math Expressions, students learn with understanding, increase language competencies, and develop sophisticated use of mathematical representations. Meaningful math activities are supported by explanations that link drawings of situations or operations to numerical methods, and by Math Talk that identifies differences, strengths, and weaknesses of different methods."
"Activities and strategies should be developed and incorporated into instructional materials to assist teachers in helping all students become proficient in mathematics”
Institute of Education Sciences/Mathematica Study Results give Math Expressions the Edge
Recently-released results from a large-scale federal study commissioned by the U.S. Department of Education's Institute of Education Sciences show that Math Expressions, published by global education leader Houghton Mifflin Harcourt, significantly outperforms other early mathematics programs in instructional effectiveness and student achievement.
“Achievement Effects of Four Early Elementary School Math Curricula” presents findings from randomized trials of first-graders in 39 schools who used various math curricula during the 2006-2007 school year. The study, which is the largest of its kind, compared the instructional approaches of four widely used elementary school mathematics programs in the United States:
Schools assigned to Math Expressions and Saxon Math reported significantly higher student achievement than those assigned to Investigations in Number, Data, and Space and Scott Foresman-Addison Wesley Mathematics (SFAW), both published by Pearson.
An average-performing student's percentile rank would improve by 9-12 points if the school used Math Expressions
Students in subgroups, including those in lower-performing schools and in schools with higher poverty levels who used Math Expressions, showed improvements greater than those using the other programs.
Chelmsford, MA School District Increases Scores by Using Math Expressions
Chelmsford School District, located in Chelmsford, MA, comprises 8 schools with a combined enrollment of 5,522. Results:
- In one year of use, Grade 3 MCAS scores increased from 63% at/above proficient to 75% at/above proficient – a gain of 12 percentage points.
- In one year of use, Grade 5 MCAS scores increased from 51% at/above proficient to 61% at/above proficient – a gain of 10 percentage points.
Woodbridge, DE School District Increases Scores by Using Math Expressions
Woodbridge School District, located in Bridgeville, DE comprises 5 schools with a combined enrollment of 1,967. Results:
- In one year of use, Grade 3 DSTP scores increased from 65.82% at/above proficient to 85.62% at/above proficient – a gain of 19.8 percentage points.
- In one year of use, Grade 5 DSTP scores increased from 75.46% at/above proficient to 81.56% at/above proficient – a gain of 6.1 percentage points.
Field Tests Show Substantial Proficiency Gains
Math Expressions from Houghton Mifflin Harcourt was field-tested in both urban and suburban classrooms, with more than 5,000 English- and non-English-speaking students. Students using Math Expressions demonstrated substantial increases in standardized test scores as well as broader measures of student learning.
“When instruction focuses on a small number of key areas of emphasis, students gain extended experience with core concepts and skills.”
