Dimensional comparisons are comparisons of one's accomplishments between two domains (e.g., comparisons between math and verbal achievements) that affect our self-perceptions in the domains compared with each other. In particular, dimensional comparisons explain the seemingly paradoxical finding, described in the internal/external frame of…

Background: The excessive use of Internet-based technologies has received a considerable attention over the past years. Despite this, there is relatively little research on how general Internet usage patterns at and outside of school as well as on weekends may be associated with mathematics achievement. Moreover, only a handful of studies have…

Peer tutoring in Mathematics has reported academic benefits across many educational levels, from Preschool to Higher Education. However, recent literature reviews and meta-analysis state that students experience higher gains in Primary or Elementary Education (ages 7-12 years) than in secondary education or middle school and high school (ages…

Spatial ability has been shown the positive correlations with the mathematics achievement of typically developing children. However, whether there is a relationship between spatial ability and mathematics achievement in deaf children and the mechanisms that underlie the relationship remain unknown. 256 deaf children in Grades 3 to 9 in two special…

Schematic chunks denote patterns, schemes, or sophisticated rules and knowledge stored in the long-term memory in the form of chunks. We investigated whether schematic chunking is effective in improving the performance of students with math difficulties (MD) and students at risk of math failure, and how the complexity level of geometry problems…

In the study reported on here I evaluated the alignment between the Annual National Assessment (ANA) and Trends in International Mathematics and Science Study (TIMSS). Theoretical perspectives were drawn from the Survey Enacted Curriculum (SEC), while quantitative correlational methods were used to determine the alignment between ANA and TIMSS…

This study investigated the reading demands of restricted-use items administered to South African grade 9 learners as part of the Trends in International Mathematics and Science Study (TIMSS) 2015. The method proposed by Mullis, Martin and Foy (2013) was used to categorise items into low, medium and high readability groups. The 'knowing' domain…

This study uses the overlap sample of about 3,500 students who participated both in the High School Longitudinal Study of 2009 (HSLS:09) and the 2013 Grade 12 National Assessment of Educational Progress (NAEP) mathematics assessment to investigate how mathematics motivation (mathematics identity, mathematics self-efficacy, and mathematics…

This study evaluates the impact of Khan Academy (KA) video tutorials in a blended learning environment for ninth grade students in Sri Lanka. The 632 treatment group students followed KA during 2-3 out of 5 time slots assigned for mathematics teaching per week. Students in the control group followed the regular class room environment with a…

Human beings have been using mathematics since they got familiar with the environment they lived in. Because of this reason, the emphasis of necessity of mathematics education for schools with various levels in different countries has undoubtedly been agreed upon. Mathematics anxiety is a problem for many people. Mathematics anxiety is one of the…

Mathematics anxiety is known to be detrimental to mathematics learning. This study explored if an embodied agent could be used to help alleviate student anxiety in classrooms. To examine this potential, agent-guided algebra lessons were developed, in which an animated agent was equipped with prescriptive instructional guidance and anxiety treating…

Teacher well-being is an important issue that needs to be considered within a teaching environment. However, little research exists about the relationship between teacher well-being and learner performance. In this study we used data from the 2015 Trends in International Mathematics and Science Study (TIMSS) to look at the interplay between…

We report on the construction, validation, and implementation of an instrument for measuring students' strategic knowledge about drawing for geometry modelling problems, namely, the "strategic knowledge about drawing scale." We conducted a qualitative study and a quantitative study to validate the proposed construction and interpretation…

International large-scale assessments (ILSAs) have become an important part of the Swedish evaluation system. It is therefore of crucial importance to validate national measures of Swedish students' achievement with their ILSA test scores. Here, we offer results from such a validation study based on Swedish students' test scores in IEA's Trends in…

This study linked ninth-grade student background data and school-reported high school transcript data from the national High School Longitudinal Study of 2009 (HSLS:09) to student item responses on the 2013 National Assessment of Educational Progress (NAEP) mathematics assessment to examine the relationships between high school coursework and…
