Evaluating the Effects of a Systemic Intervention on First-Grade Teachers’ Explicit Reading Instruction
ABSTRACT This article examines the efficacy of a multitiered systemic reading intervention for increasing the intensity and quality of explicit literacy instruction that teachers provide in first-grade classrooms. Schools (j = 16) were randomly assigned to the treatment or comparison condition. In both conditions, teachers (i = 42) provided 90 min of Tier I reading instruction to first-grade students (n = 883). In the treatment condition, Tier I classroom teachers were trained to enhance their core reading instruction by making instruction more explicit and intensive through standardized protocols and ongoing coaching support. At-risk treatment students (n = 240) also received an additional 30 min of Tier II supplemental reading intervention that was highly aligned with Tier I instruction. The focus of this study is on the Tier I portion of the multitiered intervention and the impact of the Tier I Enhancing Core Reading Instruction intervention on teacher practices. Results indicate positive effects of the Tier I intervention on the quality of explicit instruction and the frequency and accuracy of group practice opportunities provided to students.

ABSTRACT: This study developed a new survey of teachers’ knowledge about early reading and examined the effects of teachers’ knowledge on students’ reading achievement in Grades 1 to 3 in a large sample of Michigan schools. Using statistical models that controlled for teachers’ personal and professional characteristics, students’ prior reading achievement, and the clustering of high-knowledge teachers in schools and school districts with particular demographic composition, we found that the effects of teachers’ knowledge about early reading on students’ reading achievement were small. In 1st grade, students in classrooms headed by higher knowledge teachers performed better on year-end tests of reading comprehension but not word analysis. In 2nd and 3rd grades, the effects of teachers’ knowledge on either measure of students’ reading achievement were not statistically significant. Although the study suggests new forms of statistical analysis that might produce better estimates of the effects of teachers’ knowledge on students’ reading achievement, further research is needed to improve the conceptual and psychometric properties of measures of teachers’ knowledge of reading and to investigate the relation of their knowledge and their instructional practices.Journal of Research on Educational Effectiveness 10/2011; 4(4):289-321.

ABSTRACT: Implementation fidelity refers to the degree to which an intervention or programme is delivered as intended. Only by understanding and measuring whether an intervention has been implemented with fidelity can researchers and practitioners gain a better understanding of how and why an intervention works, and the extent to which outcomes can be improved. The authors undertook a critical review of existing conceptualisations of implementation fidelity and developed a new conceptual framework for understanding and measuring the process. The resulting theoretical framework requires testing by empirical research. Implementation fidelity is an important source of variation affecting the credibility and utility of research. The conceptual framework presented here offers a means for measuring this variable and understanding its place in the process of intervention implementation.Implementation Science 02/2007; 2:40. · 3.47 Impact Factor
