The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction that met Curriculum Associates' recommended usage levels on mathematics achievement, as measured by the Massachusetts Comprehensive Assessment System (MCAS) mathematics assessment. This study compared mathematics achievement growth of students who used…

An achievement gap is defined as a significant difference in academic performance between two groups. Massachusetts Comprehensive Assessment System (MCAS) data indicate that, in Crestland Public School District (pseudonym), there is a clear achievement gap in mathematics between students with disabilities and those without disabilities,…

The ASSISTments project is an ecosystem of a few hundred teachers, a platform, and researchers working together. Development professionals help train teachers and get teachers to participate in studies. The platform and these teachers help researchers (sometimes explicitly and sometimes implicitly) simply by using content the teacher selects. The…

Comparison is a powerful tool that has been shown to improve learning in a variety of domains. In both laboratory studies and small-scale classroom studies, having learners compare and contrast worked examples has been shown to reliably lead to gains in students' knowledge. Comparison is also integral to "best practices" in mathematics…

This article describes research results based on multiple years of experimentation and real-world experience with an adaptive tutoring system named Wayang Outpost. The system represents a novel adaptive learning technology that has shown successful outcomes with thousands of students, and provided teachers with valuable information about students'…

Math Snacks animations and support materials were developed for use on the web and mobile technologies to teach ratio, proportion, scale factor, and number line concepts using a multi-modal approach. Included in Math Snacks are: Animations which promote the visualization of a concept image; written lessons which provide cognitive complexity for…

In recent decades, the Commonwealth of Massachusetts has implemented reforms aimed at improving and controlling the quality of the teaching workforce in public schools. Among those reforms are tests for licensure that assess both general and content-area specific knowledge, requirements for ongoing teacher professional development, and procedures…

In this paper, we investigate the correspondence between student affect and behavioural engagement in a web-based tutoring platform throughout the school year and learning outcomes at the end of the year on a high-stakes mathematics exam in a manner that is both longitudinal and fine-grained. Affect and behaviour detectors are used to estimate…

Problem solving, introduced in every grade and practiced throughout elementary school, is an essential foundation on which students build their understanding of mathematical ideas, operations, and relationships. This article discusses 1-2-3 Time, an instructional mode that promotes multimodal math learning in ways that engage and sustain students'…

Four organizations with promising practices in teacher Professional Growth & Support have significantly raised outcomes for low-income students. The charter management networks, Achievement First and Aspire Public Schools, and the two reform organizations, Teach Plus and Agile Mind, have successfully increased student achievement with a…

Less than one third of American eighth graders score in the two highest performance levels on the grade 8 mathematics test given by the National Assessment of Educational Progress. Only a little over one third of Massachusetts eighth graders score at the two highest performance levels on the state's own grade 8 mathematics test. In 2002, the…

Limited classroom time available in middle school mathematics classes forces teachers to choose between assisting students' development and assessing students' abilities. To help teachers make better use of their time, we are integrating assistance and assessment by utilizing a web-based system, ASSISTment, that will offer instruction to students…

Low-test scores in literacy and mathematics have resulted in increased accountability for educators, as evidenced by statewide "high stakes: testing. The push by federal and state mandates, such as the "No Child Left Behind" Act and the Massachusetts Comprehensive Assessment System (MCAS) have increased the amount of teaching and…

Teachers may be the most important element of an effective school, but does that mean that K-12 improvement must wait on the ability of schools or systems to recruit, nurture, and retain outstanding teachers? Such a strategy implies that widespread excellence hinges on the ability of publicly funded school systems to attract more than 3.3 million…

During the past several years, school superintendents and educational leaders from around the country have convened at the Pearson Education Instructional Leadership Council to discuss solutions for some of the most pressing issues they confront, especially regarding teaching and learning. Several common change principles have emerged from these…
