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…

Energy is considered both a core idea and a crosscutting concept in science education. A thorough understanding of the energy concept is thought to help students learn about other (related) concepts within and across science subjects, thereby fostering scientific literacy. This study investigates students' progression in understanding the energy…

The purposes of this study were to (a) develop and validate instruments to assess elementary students' scientific creativity and science inquiry, (b) investigate the relationship between the two competencies, and (c) compare the two competencies among different grade level students. The scientific creativity test was composed of 7 open-ended items…

A quasi-experimental, pretest-posttest, non-equivalent control group design was used to examine the effect of a mobile gamification application on third and fourth grade students' Spanish language achievement and student academic self-efficacy. In this study, the treatment group's Spanish language instruction was through the use of…

Limited research exists concerning the effect of interactive electronic texts or eBooks on the reading comprehension of students with reading disabilities. The purpose of this study was to determine if there was a significant difference in oral retelling and comprehension performance on multiple-choice questions when 17 students with reading…

Oral reading tasks and Maze reading tasks are often used interchangeably to assess the level and rate of reading skill development. This study examined the concurrent validity of growth estimates derived from "Curriculum-Based Measurement of Oral Reading" (CBM-R) and "Maze Reading" (CBM-mR). Participants were 1,528 students…

Conceptual change requires learners to restructure parts of their conceptual knowledge base. Prior research has identified the fragmentation and the integration of knowledge as 2 important component processes of knowledge restructuring but remains unclear as to their relative importance and the time of their occurrence during development. Previous…

In this technical report, we present the results of a reliability study of the third-grade multiple choice reading comprehension measures available on the easyCBM learning system conducted in the spring of 2011. Analyses include split-half reliability, alternate form reliability, person and item reliability as derived from Rasch analysis,…

In this series of studies, we investigated the technical adequacy of three curriculum-based measures used as benchmarks and for monitoring progress in three critical reading- related skills: fluency, reading comprehension, and vocabulary. In particular, we examined the following easyCBM measurement across grades 3-7 at fall, winter, and spring…
