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…

Number system knowledge (NSK) is broadly defined as the understanding of number relationships and is an essential mathematics skill for young elementary school-aged students. NSK instruction that emphasizes connections between number sense and spatial reasoning could be a critical anchor for second-grade students to stay rooted in their conceptual…

The aim of this study was to determine the dimensions of the relationship between math anxiety and mathematics achievement of the third grade students with and without mathematics learning difficulties. Data were collected from 288 elementary school students using math anxiety scale and math achievement test tools. The mathematics achievement test…

In recent years, scholars have increasingly advocated the importance of cultivating non-cognitive skills (social and emotional skills) in early childhood, and play is useful in acquiring the skills. Simultaneously, young children also need to acquire mathematical cognitive skills as a learning foundation. However, many researchers have indicated…

Assessment is a crucial factor in the implementation of curriculum reform. Little is known, however, on how curriculum changes can be reflected adequately in assessment, particularly if the reform concerns process skills. This issue was investigated for the case of assessing mathematical thinking in a mathematics curriculum reform for…

Assessment items are commonly field tested prior to operational use to observe statistical item properties such as difficulty. Item parameter estimates from field testing may be used to assign scores via pre-equating or computer adaptive designs. This study examined differences between item difficulty estimates based on field test and operational…
