To advance the research examining the sluggish cognitive tempo (SCT) construct, a key priority has been to develop assessment tools that are reliable and valid. The current study builds upon existing work by conducting the most thorough psychometric evaluation to date of the teacher-reported Child and Adolescent Behavior Inventory (CABI) SCT and…

This study examined the effectiveness of the intensive implementation of a multicomponent reading intervention (Voyager Passport) with 306 fourth grade students with severe reading difficulties. Students with reading comprehension achievement below the 15%ile in the fall of fourth grade were randomly assigned to the intensive intervention or to…

Growing up in poverty increases youth risk for developing aggressive behavior problems which, in turn, are associated with a host of problematic outcomes, including school drop-out, substance use, mental health problems, and delinquency. In part, this may be due to exposure to adverse school contexts that create socialization influences supporting…

Although mathematics development research has become more prominent in the school psychology literature in recent years, a large research gap in this area exists regarding English language learners (ELLs). Significant research in education, cognitive science, and psychology has been devoted to understanding the links between language and…

Teaching vocabulary and reading comprehension during social studies instruction is critical for reading development and the acquisition of content knowledge. This study systematically investigated how elementary teachers integrate vocabulary and reading comprehension instruction during social studies teaching, as well as the extent to which this…

Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in the release of the Next Generation Science Standards (NGSS) in 2013. The new standards set off a chain reaction of standards adoption and…

Oral reading fluency (ORF), used by teachers and school districts across the country to screen and progress monitor at-risk readers, has been documented as a good indicator of reading comprehension and overall reading competence. In traditional ORF administration, students are given one minute to read a grade-level passage, after which the…

Prevention scientists recognize that implementing effective prevention practices and programs responsive to the needs of individuals but based solely upon the findings from variable-centered methods presents several limitations due to numerous risk factors, pathways, and unobserved influences. One such understudied influence that is masked by…

In this multi-year study, we taught English/Language Arts teachers of students with Learning Disabilities in middle school to incorporate 15 minutes of daily vocabulary activities with students in their intact special education English/Language Arts classes. During Year 1, teachers taught 48 words to their sixth grade students, who learned and…

Purpose: The Santa Ana Unified School District received an i3 grant (Investing in Innovation; funded by the U.S. Department of Education Grant number U411C160074) to build on their existing school climate practices. Called the Enhanced Positive School Climate Model, the aim is to improve school climate, student-adult relationships, create social…

Automatic speech recognition (ASR) can be used to score oral reading fuency (ORF) assessments to ameliorate current inadequacies (e.g., administration errors, high opportunity cost), and represents an important part of a larger solution to improve traditional ORF. But more research is needed on how ASR performs for diverse student groups. The…

The purpose of this causal-comparative study was to gain insight into whether teaching fractions improves teachers' understanding of fractions. University master's students (n = 25) conducted tutoring focused on fraction magnitude using number line representations across 39 sessions (3 per week) at grades 3-5. The contrast condition, 17 master's…

Expressive writing (EW), or writing about one's thoughts and feelings, has been posited to reduce the working memory (WM) load that pressure and anxiety can impose on test-takers. The mechanisms of EW are far from clear, however, and social and developmental questions about its role in shaping children's engagement with academic contexts remain.…
