We explore the relationship between video playback speed and student learning outcomes. Using an experimental design, we present the results of a pre-registered study that assigns users to watch videos at either 1.0x or 1.25x speed. We find that students who consume sped content are more likely to get better grades in a course, attempt more…

The problem this qualitative case study addressed is how poor online teacher communication has resulted in students enrolled in full-time virtual schools underperforming academically with assignment completion. The purpose of this study was to explore teachers' perceptions of how their online communication strategies contribute to the timeliness…

Based on 1,364 children across Grades 1, 3, and 5, the present study explored the mutualism of (externalizing and internalizing) behavioral problems and language, and whether social skills explained such mutualism. The random intercept cross-lagged panel models were conducted to control for between-person level variance and to explore mutualism of…

Many educators in California are unaware of just how harmful out of school suspensions can be. When suspended students are barred from attending school, more often than not, the rule broken was some form of minor misconduct. This update of "Lost Instruction Time in California Schools" demonstrates that despite the important efforts by…

Math education consultant Marilyn Burns finds that teachers ask her the same three questions so often she's named them "The Big Three": What can I do with students who finish their math work more quickly?, How can I free up time to work with kids who need extra help?, and How can I differentiate math learning experiences? Burns, who…

This report is the first to analyze California's school discipline data as measured by days of missed instruction due to suspension. The state reports the number of suspensions for each district, disaggregated by racial/ethnic groups, but it does not provide any information on how much instructional time was lost. The authors used information from…

Allocated classroom time is not the same as time available for learning--a host of economic and social stressors undermine learning time in schools serving low-income students. When time is limited, it is hard to meet rigorous learning standards. The challenge is compounded in high-poverty schools where community stressors place additional demands…

Policy and practice have charged forward with emphasizing the necessity to reduce school absenteeism in the fall (i.e., Attendance Awareness Month). However, no empirical basis served to bolster these efforts. This study examined whether fall versus spring absenteeism was linked to spring state exam scores for a sample of elementary students over…

Foundations across the country engage in grantmaking to eliminate the opportunity and achievement gaps in K-12 public schools. Many of the strategies and investments that funders have supported in recent years focus not only on "more time" but also on "better use of time" in schools. This better use of time centers on outcomes…

While the statewide trends and disparities suggest that the rate of lost instruction in California due to out-of-school suspension (OSS) is about where it was before the COVID-19 school closures, this is the first report to highlight how post-COVID suspensions in 2021-2022 have added to the pandemic's harmful impact of instructional loss,…
