Sources of longitudinal achievement data are increasing thanks partially to the expansion of available interim assessments. These tests are often used to monitor the progress of students, classrooms, and schools within and across school years. Yet, few statistical models equipped to approximate the distinctly seasonal patterns in the data exist,…

The Common Core State Standards for Mathematics have a widespread impact on children's statistical learning opportunities. The Grade 6 standards are particularly ambitious in the goals they set. In this critique, experiences helping children work toward the Grade 6 Common Core statistics expectations are used in conjunction with previous research…

School Improvement Grants (SIGs) exemplify a capacity-building investment to spur sustainable changes in America's persistently lowest-performing schools and stimulate the economy. This study examines both short- and longer-term effects of the first two cohorts of SIG schools from four locations across the country. Dynamic…

The criterion problem was one of the focal points of early studies of creativity, but several useful criteria have been developed in the last few decades. The investigation reported here represents additional progress. This report (a) describes a new quality of creative achievement index for each domain of the Creative Activity and Accomplishment…

This study aims to determine students' characteristics that predict their academic success. The study group consisted of 4,229 students studying at middle schools in Burdur. The data were collected using a questionnaire in the 2014-2015 academic year and analyzed using CHAID (Chi-squared Automatic Interaction Detection) analysis, a type of…

Difficulties with rational numbers have been explained by a natural number bias, where concepts of natural numbers are inappropriately applied to rational numbers. Overcoming this difficulty may require a radical restructuring of previous knowledge. In order to capture this development, we examined third- to fifth-grade students' understanding of…

In this single-subject study, we examined the effects of a summarizing strategy on the written summaries of children with emotional and behavioral disorders (EBDs). Six students with EBDs in fifth and sixth grades learned a mnemonic-based strategy for summarizing taught through the self-regulated strategy development (SRSD) approach. Visual…

In this study we introduce an infusion model to "inject" ammonites and ammonite fossils in current subjects of Greek primary curriculum. Paleontology and mainly fossils attract more and more elementary students and teachers, yet in Greece this trend is solely about dinosaurs, despite the fact that the most common Greek fossils are not…

This article reports on the development of an online dynamic approach for assessing and improving students' reading comprehension of science texts--the dynamic assessment for reading comprehension of science text (DARCST). The DARCST blended assessment and response-specific instruction into a holistic learning task for grades 5 and 6 students. The…

This study addressed computer-supported collaborative scientific inquiries in remote networked schools (Quebec, Canada). Three dyads of Grade 5-6 classrooms from remote locations across the province collaborated using the knowledge-building tool Knowledge Forum. Customized scaffold supports embedded in the online tool were used to support student…

Physical exercise is acknowledged to play a highly significant role in human health and life quality. The concept "Quality of Life" (QoL) refers to many parameters, including the individual's physical condition, psychological status, level of independence, social relationships and interaction with the environment. Participating in dance…

In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from prior studies. This supplementary report presents the results of the additional analyses addressing classification accuracy, reliability, and criterion-related validity evidence. For ease of reference, we…

This research examined the process and conditions of social projection of biased ethnic attitudes to classmates in two samples of Grades 4-6 children (n = 342, M[subscript age] = 10.75, SD = 0.98; 49% girls; and n = 525, M[subscript age] = 10.49 years, SD = 0.96; 51% girls). Children reported on the ethnic group norm in their classroom and on…

Background: We examined longitudinal changes in children's physical activity during the school day, afterschool, and evening across fifth, sixth, and seventh grades. Methods: The analytical sample included children who had valid accelerometer data in fifth grade and at least one other time-point, and provided complete sociodemographic information…
