We present the results of a study of local education agency (LEA)-based interventions to improve the reading outcomes of struggling readers in sixth grade. The sample included 1,076 intervention students and 3,644 comparison students. Regression discontinuity was used to evaluate intervention impact. The study contributes to the field by…

This study examined the effectiveness of Zipfian frequency at facilitating the acquisition of English prenominal past participles. Chinese middle school students (N = 103) were randomly assigned to a sequenced Zipfian frequency (SZF) group, a random Zipfian frequency (RZF) group, a balanced frequency (BF) group, and a control group. A mixed…

In recent years, the regression discontinuity design (RDD) has gained widespread recognition as a quasi-experimental method that when used correctly, can produce internally valid estimates of causal effects of a treatment, a program or an intervention (hereafter referred to as treatment effects). In an RDD study, subjects or groups of subjects…

This paper provides causal evidence to answer the question, "Does the application of a double dose of literacy instruction in middle school improve student performance on subsequent academic outcomes?" The focus of this paper is on an intervention where the second dose of literacy instruction uses research-based instructional strategies,…

Technology is an increasing part in the lives of junior high students, but little is known about how this technology affects their reading. Reading comprehension from e-books is compared to reading comprehension from conventional print books with junior high students. The problem is that students may be reading from a medium that is less than the…

One of the most widely used commercially available systems incorporating benchmark assessment and training in differentiated instruction is the Northwest Evaluation Association's (NWEA) Measures of Academic Progress (MAP) program. The MAP program involves two components: (1) computer-adaptive assessments administered to students three to four…

The primary aim of the Middle School Intervention Project (MSIP) is to evaluate the impact of a multi-component intervention for struggling adolescent readers on reading outcomes. The intervention consists of: (1) targeted, Tier 2 reading and (2) school engagement interventions, and (3) data-based-decision-making (DBDM) teams to review and act on…

This investigation examined the effects and consequences of using testing accommodations, including reading aloud test content, with a group of eighth-grade students (N = 79) on a standardized reading test. Research questions pertaining to the effects of accommodations on reading test scores and consequences of testing on teacher and student…
