The Cattell-Horn-Carroll (CHC) model presently serves as a blueprint for both test development and a taxonomy for clinical interpretation of modern tests of cognitive ability. Accordingly, the trend among test publishers has been toward creating tests that provide users with an ever-increasing array of scores that comport with CHC. However, an…

This study examines the effects of adoption of ACT® Aspire® Periodic Assessments on student academic growth, as measured by the ACT Aspire Summative Assessments. A difference-in-difference analysis shows that adoption of the ACT Aspire Interim Assessments leads to improvements in academic growth. Averaging results across all subject areas and…

Despite the widespread use of social educational tools during the last decade in K12 education, the growth curve of utilizing these tools to enhance reading activities has remained lower than expected in learning environments. However, the rapid shift from face-to-face education to online education brought about by the pandemic has attracted…

In this paper, six mathematics curriculum changes in Iran will be reviewed, spanning from 1900 until the present time. At first, change forces, barriers, and the main features of each curriculum reform will be represented. The first five curriculum changes are described briefly and the sixth and most recent curriculum reform will be elaborated. In…

Young children are sensitive to both numerical and spatial magnitude cues early in development, but many questions remain about how children's attention to magnitudes relates to their early math achievement. In two studies, we tested three hypotheses related to the flexible attention to magnitudes (FAM) account, which suggests that young…

This paper examines competency-based educational policy-making in a global context. Specifically, it explores how the thinking around competency, spearheaded by international organisations and experts, has led to the development and deployment of a particular notion of global competency. Drawing on critical policy research, I examine three…

Developing an understanding of fractions is critical as a significant predictor for the learning progression of advanced domains; however, students face significant challenges in learning fractions because of their unique properties. To systematically approach remediation, this study examined the common error patterns committed by middle-school…

This study investigated developmental trajectories of reading and math using latent-growth-curve analyses across multiple academic skills, measures, and multiple time periods within a single sample. Reading-related growth was marked by significant individual differences during the early elementary-school period and nonsignificant individual…

The first batch of graduates in the country under the K-12 curriculum graduated in 2018. Thus, a call for an evaluation of students' acquired competency is essential. That's why, there is a need for the construction of assessment tools. In this study, a valid, reliable, and item quality achievement test in General Mathematics was developed. Eight…

The simple views of reading (SVR) and writing (SVW) provide useful foundations for the interpretation of psychoeducational achievement batteries. Research has established that oral language, decoding, and transcription explain significant variance in reading comprehension and written composition, respectively. However, the specific task demands of…

This study analysed secondary TIMSS 2019 data for respondents from South Africa and proposed a model containing ten constructs; nine independent variables (socio-economic status and eight variables about safety aspects in schools) and one independent variable (mathematics achievement). Qualitative data was also collected using interviews and field…

In this article we carry out a preliminary reconstitution of the genealogy of the political decision to integrate Portugal in PISA (Programme for International Student Assessment), promoted by the Organisation for Economic Co-operation and Development, made in 1999 and implemented in 2000. For this we used a comprehensive analysis of newspaper…

Using a randomized controlled trial, we examined the effect of a fractions intervention for students experiencing mathematical difficulties in Grade 5. Students who were eligible for the study (n = 205) were randomly assigned to intervention and comparison conditions, blocked by teacher. The intervention used systematic, explicit instruction and…

The Tennessee Voluntary Pre-K Program (TN-VPK) is statewide full-day program that gives priority to children from low-income families. A regression-discontinuity design with a statewide probability sample of 155 TN-VPK classrooms and 5,189 children participating across two pre-K cohorts found positive effects at kindergarten entry with the largest…

This study examined the effects of the cross-curricular model of integrating mathematics and science with experiential learning on the knowledge of 3rd grade primary school pupils in Slovenia. The purpose of this research was to design and implement school lessons rooted in integrating maths with science and concrete experience, and handling real…
