This study aimed to examine the measurement invariance of the mathematical affective characteristics model obtained from TIMSS 2015 4th grade Turkey administration according to home resources. For this purpose, firstly, the factor structure of the mathematical affective characteristics questionnaire was examined by explanatory factor analysis and…

There is a considerable body of research on children's number knowledge development, and in particular on children ages 4 years and older and who have some counting experience. Children in early care preschool settings (ages 2 and 3) and who are not yet experienced counters are an understudied population. We conducted a multiple-case study on five…

Rational Numbers is an essential topic in mathematics since it necessitates the learning progression of more advanced topics. Nevertheless, previous literature shows that students are having difficulties in understanding the topic for numerous reasons. The inability of teachers in providing good examples during teaching is identified as one of the…

The effectiveness of class size reduction on student performance has been of great research interest and policy debate worldwide. Nevertheless, the evidence has been largely inconclusive partially due to potential bias arising from non-random placement of students and teachers in classrooms of different sizes. This study applied instrumental…

According to data from the National Assessment of Educational Progress, or NAEP, the U.S. educational system has consistently failed Black and Brown children across both reading and mathematics. Educational research has further uncovered the ways that reading and mathematics assessment and curriculum are often biased and culturally and…

The effects of (a) private room, (b) typical classroom, and (c) high-distraction room test settings were examined on the math test performance of six college students (four females) with ADHD. Participants (aged 18-30 years) completed multiple, equivalent algebra calculation tests (100 items each) under the three test-setting conditions. A…

This study details the construction of parameters for generating subskill mastery math measures to be used for screening, intervention planning, progress monitoring, and proximal program evaluation. Parameters for generating assessment measures were built and tested to verify initial equivalence of generated measures using potential digits correct…

Ensuring students master their basic facts is a shared priority among teachers, parents, and administrators. As a result, the number of available resources for basic facts instruction, from concrete to virtual, is vast and continues to grow. Basic fact fluency has always been of interest to elementary school teachers and is particularly relevant…

We evaluate the feasibility of estimating test-score growth with a gap year in testing data, informing the scenario when state testing resumes after the 2020 COVID-19-induced test stoppage. Our research design is to simulate a gap year in testing using pre-COVID-19 data--when a true test gap did not occur--which facilitates comparisons of…

This paper describes the development and efficacy of an online tool for assessing the numeracy of undergraduate students. The tool was designed to be easy to administer, provide immediate feedback to students on whether they had the required level of numeracy, and to be consistent with other measures of adult numeracy. When used with students…

This quantitative, causal-comparative ex-post-facto study primarily examined differences in mathematics achievement between Latinx English Learner (EL) fourth-grade students instructed in English and Spanish within one-way dual/developmental additive elementary bilingual language programs but tested in English. Additional analyses examined the…

Measures of teacher mathematical knowledge are notoriously difficult to develop (e.g., Orrill et al., 2015). This is in part because of the multidimensional nature of teacher knowledge. As part of two separate projects being undertaken by this research team, we have attempted to write assessments of teacher pedagogical content knowledge (PCK) in…

In the 21st century, teaching and learning mathematics courses witness significant expansion and development of technology use, which creates a shift from teacher-centred to student-centred learning engagement. Student engagement (SE) faces many challenges of poor performance and student difficulty in solving simultaneous equations involving…

The students' perception of how they are positioned by their teachers offer valuable insights into how teachers might engage students in the act of learning, construct themselves and acts in ways desirable to students, and how they might make the learning process a more enjoyable one for students. Teacher positioning is an important factor in…

Deliberate practice and having a growth mindset have been hypothesized to increase school performance. But previous studies are few, have been limited to very short interventions, and on average resulted in small effect sizes on school performance. This study compared the attitudes, performance, and behavior of 130 7th-grade students taking part…
