Inspired by complex system theory, this study adopts a multilevel piecewise regression model to examine the relationship between homework time and the development of students in different grades using a large-scale testing database in China. The results indicate that the relationship between homework time and students' performance is positive when…

This investigation scrutinizes the relative effectiveness of individual versus bundled accommodations -- specifically, breaks and extended time (ET) -- on the performance, behaviors, and attitudes of eighth-grade students with disabilities during the 2017 National Assessment of Educational Progress (NAEP) digital math test. Through a detailed…

Homework is a self-regulated activity that constitutes a large proportion of learning time. In mathematics, how long is the optimal homework time for achievement development and how to improve homework time efficiency have long been questions. The study examined how mathematics homework time was related to mathematics achievement among Chinese…

With an educational issue that has caught the attention of many countries in the world (study load), a population of 8th graders from a typical Chinese metropolitan city (40,536 from 118 schools), and an advanced statistical strategy (multilevel piecewise regression), we examined whether there was a turning point in terms of the effects of study…

The shift to online teaching during the COVID-19 pandemic forced schools to swiftly develop strategies for virtual settings to ensure students received effective instruction. Antecedent- and consequence-based interventions have been shown to be effective in classrooms; however, to our best knowledge, there have been no reports on the effects of…

When student achievement is assessed, we seek to elicit a student's maximum performance -- a goal requiring the assumption that the student is fully engaged. Otherwise, to the extent that disengagement occurs, test performance is likely to suffer. Effectively managing test-taking disengagement requires an understanding of the testing conditions…

Students with high incidence disabilities in the public school system often perform multiple grade levels below their typically developing peers in mathematics achievement. These students exhibit lower levels of on-task behavior that limits their access to effective instruction, thus requiring instructional interventions that personalize learning,…
