There are great expectations regarding the potential contribution of integrated care interventions to improved outcomes, but so far the evidence is mixed. In this dissertation, we focussed on why, when and how some integrated care interventions contribute to improved outcomes, while others do not. To this purpose, we developed the COMIC Model for studying the Context, Outcomes and Mechanisms of...

INTRODUCTION Low-income children are especially at risk for low fruit and vegetable consumption. Diets lacking in fruits and vegetables are associated with chronic diseases. Successful school-based interventions are key to promoting the consumption of fruits and vegetables. Research has shown that the degree of teacher involvement has a significant impact on students' and parents' interest in a...

Technology implementation research indicates that teachers’ beliefs and knowledge, as well as a host of institutional factors, can influence technology integration. Drawing on third-generation activity theory, this article concep­ tualizes technology implementation as a network of planning and integration activities carried out by technology specialists, teachers, and administrators. The resear...

This paper analyzes a coaching model focused on classroom management skills and instructional practices across grade levels and subject areas. We describe the design and implementation of MATCH Teacher Coaching among an initial cohort of fifty-nine teachers working in New Orleans charter schools. We evaluate the effect of the program on teachers’ instructional practices using a block randomized...

Instructional policy reforms that focus on standards and assessments have gained popularity in the last two decades. State governments, which had previously left most instructional matters to local governance, set challenging learning standards and developed related assessments and curricular frameworks. Despite their popularity and persistence, standards-based reforms face the challenge of suc...

A line-smoothing algorithm based on simple arithmetic is presented and its characteristics are analyzed for various implementations. The algorithm is efficient because it can be implemented using only simple integer arithmetic, with no square root or trigonometric calculations. The algorithm is applicable to graph drawing applications that require smooth polylines between graph nodes. Though th...

This study examined technology implementation practices associated with student learning gains. Interviews and observations were conducted with staff at schools where teachers using reading or mathematics software with their students attained above-average achievement gains and at schools where software-using teachers had below-average gains. The findings highlight the importance of school prac...

This article analyzes a coaching model focused on classroom management skills and instructional practices across grade levels and subject areas. We describe the design and implementation of MATCH Teacher Coaching among an initial cohort of 59 teachers working in New Orleans charter schools. We evaluate the effect of the program on teachers’ instructional practices using a block randomized trial...
