The purpose of this study was to examine the presence of gender and ELL Differential Item Functioning (DIF) in a teacher-created mathematics benchmark test in one public charter school district in Northeast Georgia. DIF occurs when an item behaves differently in different subgroups, rather than measuring a test taker's true ability. The geometry…

This paper provides a set of five indicators of CAS use, which provide a means to analyse a student's written solution to determine whether they used CAS for solving a given problem. These indicators provide a way for researchers and teachers to determine CAS use without requiring classroom observation or the explicit recording of extra…

Elementary school students often exhibit a variety of conceptions associated with algebraic thinking that their teachers fail to recognize or understand. It is crucial that elementary school teachers possess knowledge of the variety of student conceptions and also have abilities to address varying states of conceptions. Otherwise, students who are…

Most studies predicting college performance from high-school grade point average (HSGPA) and college admissions test scores use single-level regression models that conflate relationships within and between high schools. Because grading standards vary among high schools, these relationships are likely to differ within and between schools. We used…

Many students around the world are exposed to a rote teaching style in mathematics that emphasizes memorization of procedures. Students are frequently presented with standard types of equations in their textbooks, in which the equal sign is immediately preceding the answer (a + b = c). This exposure can lead to many misconceptions, such as…

This study examined the effect of mastery learning on senior secondary school students' achievement and retention in circle geometry. The study was conducted in Ilorin, Kwara state, Nigeria. It adopted a quasi-experimental, non-randomized, pre-test, post-test control group design. A sample of 172 senior school II students was drawn from four…

Increasing classroom attendance rates is important to improving success in developmental mathematics courses. Our results indicated that absence rates begin to increase after the first exam. Furthermore, the number of absences gradually increased throughout the semester and a higher proportion of class meeting time was missed in classes that met…

The study endeavored to determine if teaching test-taking strategies had an impact on the students' performance on the ACT science subsection exam. Students received test-taking strategies instruction for the ACT science subsection exam. Students were administered a pre-and post-test, confidence survey, and strategies ranking list. The study also…

Curricular analysis indicates that the U.S. students are introduced to multiplication in additive terms (as the replication of equal groups and repeated addition). But the virtue of this introduction for supporting students' understanding of the full range of multiplicative relationships is unclear. This paper reports an analysis of all grade 4…

The unification of South Korea and North Korea is a plausible idea yet it requires a comprehensive preparation in advance. As a method to achieve fiscal efficiency in public services, decentralization theory is consistently applied. However, the current literature and political reality argue that decentralization does not always hold its…

The literature shows that the integration of technological tools, like "GeoGebra," has the potential to improve the teaching and learning of mathematics. The aim of this study was to see whether "GeoGebra" could be used to address identified, systematic misconceptions that National Certificate Vocational (NCV) students hold…

This study examined the influence of the jigsaw co-operative learning strategy integrated with GeoGebra (JCLGS), on Ethiopian undergraduate statistics and chemistry learners' conceptual knowledge development and attitudinal change towards calculus. The post-positivism quantitative methods approach employed in a non-equivalent pre-and post-test…

We report the results of a preregistered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no 2 consecutive problems require the same…

This research is a secondary analysis with Korean students' data collected in the TIMSS 2015 to describe the moderation effects of instructional practices on the relationships between students' emotional dispositions toward mathematics and mathematics achievement. From the TIMSS 2015 database, we collected mathematics achievement scores, a…

We present first-grade, second-grade, and third-grade impacts for a first-grade intervention targeting the conceptual and procedural bases that support arithmetic. At-risk students (average age at pretest = 6.5) were randomly assigned to three conditions: a control group (n = 224) and two variants of the intervention (same conceptual instruction…
