Researchers often develop instruments using correctness scores (and a variety of theories and techniques, such as Item Response Theory) for validation and scoring. Less frequently, observations of children's strategies are incorporated into the design, development, and application of assessments. We conducted individual interviews of 833…

In educational and psychological research, it is common to use latent factors to represent constructs and then to examine covariate effects on these latent factors. Using empirical data, this study applied three approaches to covariate effects on latent factors: the multiple-indicator multiple-cause (MIMIC) approach, multiple group confirmatory…

Most national assessments in education focus on the curriculum to identify the knowledge and skills students should have acquired. Applying this approach to international assessments poses several challenges that need to be addressed in the design and implementation of international studies. This Compass Brief explains the advantages and…

Using the Trends in International Mathematics and Science Study Data (TIMSS) 2015 dataset, this study examines 30 different contextual indicators to determine significant predictors of girls' mathematics achievement globally. The study design employs three nested levels in the hierarchical linear model (individual, classroom, and nation) to…

A series of course-specific MAP Growth Mathematics and Science subject tests were released successively starting in August 2017 to replace the older NWEA End-of-Course (EOC) tests. Different from the prior NWEA EOC tests taken only at the end of a course, these course-specific tests can be administered multiple times throughout the school year,…

This study used a propensity score approach to estimate treatment effects in a multilevel setting. The propensity score approach involves the estimation of propensity scores for covariate balancing and the estimation of treatment effects. This study aimed at understanding how propensity scores estimated through a simple logistic regression compare…

This explanatory mixed-methods study explored if there was a change in student progress as measured by STAR percentile rank due to the multiple instructional modalities caused by the COVID-19 pandemic. Educational institutions had to shift to distance learning in March of 2020 due to the outbreak of COVID-19. The return to school for the 2020-2021…

Alaska has implemented an innovative approach to a balanced assessment system called the Alaska System of Academic Readiness (AK STAR). The AK STAR summative assessments are administered each spring to students in grades 3-9. The AK STAR assessments were developed to provide information on student achievement, areas of strength and need, and…

In this research, structural equation modeling and TIMSS data were employed to examine the impact of school belonging on math achievement among secondary students in Japan, Korea, and the United States, with a focus on the roles of math attitude and disorderly behavior. Utilizing SmartPLS 4.0, the study delved into the reliability and validity of…

In learning, errors are ubiquitous and inevitable. As these errors may signal otherwise latent cognitive processes, tutors--and students alike--can greatly benefit from the information they provide. In this paper, we introduce and evaluate the Systematic Error Tracing (SET) model that identifies the possible causes of systematically observed…

We report on the construction and validation of the Young Children's Math Anxiety Scale (YCMAX), a developmentally appropriate measure of math anxiety intended for kindergarten students. We administered the YCMAX to a sample of public school kindergarteners (N = 355) and conducted factor analyses to examine its structure. A two-factor solution…

The aims of this study are investigating the attention ability and geometry skills of 60-72-month-old children according to the socio-economic status and determining whether the attention ability significantly predicts the geometry skill when the socio-economic status is controlled. The accessible population of the research in the relational…

This research aims to scrutinize the moderating effect of teacher interaction on the relationships between students' self-efficacy and achievement in mathematics in three countries, Korea, Singapore, and the USA. We analyzed the Trends in International Mathematics and Science Study (TIMSS) 2015 data with hierarchical linear modeling. The findings…

The objective of this development research is to create an android application of probability theory of the same element permutation material based on RME as a learning medium, as well as to assess the quality of the apps created for utilize in learning mathematics. This research used research and development (R&D) method with the 4D…

Using data from the Trends in International Mathematics and Science Study (TIMSS) 2015 assessment of fourth-grade students in 32 countries, a series of mean comparisons and regression analyses were conducted to determine (1) the gender gap in students' self-concept in mathematics; (2) to what extent student achievement, student gender, and…
