This study examined the effect of gamification on visual programming and computational thinking skills among primary school students, aiming to investigate how gamified learning environments enhance cognitive skill development and conceptual integration compared to traditional teaching methods. A quasi-experimental design was employed, involving…

Zearn Math is a popular software platform for K-8 mathematics learning, designed to enable all students to successfully access grade-level content. RAND researchers collaborated with Zearn, the product's developer, to design this evaluation. Then RAND conducted the study independently, randomly assigning 64 schools in an urban Texas district to…

Cheating detection is an important issue in standardized testing, especially in large-scale settings. Statistical approaches are often computationally intensive and require specialised software to conduct. We present a two-stage approach that quickly filters suspected groups using statistical testing on an IRT-based answer-copying index. We also…

In this study, it was aimed to determine the effect of Plickers, which is one of the Web 2.0 education tools, on success in affix-root teaching to 5th grade students. In the study, random design with pretest-posttest control group, which is one of the real trial models, was used. The study group of the study was determined by homogeneous sampling…

Main idea and summary are essential elements of reading comprehension. We report results from Grades 4 and 5 student performance on two years of state-mandated standardized reading testing which indicate that students perform statistically significantly lower on main idea and summary questions on the tests than any other question category. In this…

Intraclass correlations are used to summarize the variance decomposition in popula- tions with multilevel hierarchical structure. There has recently been considerable interest in estimating intraclass correlations from surveys or designed experiments to provide design parameters for planning future large-scale randomized experiments. The large…

In this mixed method research, we examined the effects of reading and singing software program (RSSP) as a reading intervention on struggling readers' reading achievement as measured by the Florida Comprehensive Assessment Test, the high stakes state test administered in the state of Florida, at one elementary school. Our team defined struggling…

In the social sciences, latent traits often have a hierarchical structure, and data can be sampled from multiple levels. Both hierarchical latent traits and multilevel data can occur simultaneously. In this study, we developed a general class of item response theory models to accommodate both hierarchical latent traits and multilevel data. The…

K-12 school practitioners and schools administrators need reliable results about the effects of instructional technology products as they strive to meet achievement compliance levels in politically accountable local and national contexts in the U.S. This study presents evidence regarding the effects of extensive engagement with computer-based…
