Despite the importance of parallelism concept in understanding advanced geometric concepts, past studies have constantly reported poor mastery of this concept. To pinpoint students' current states in the progression of parallelism concept acquisition, this study aimed to profile students' knowledge states and model their learning pathways.…

Mastery learning improves learning proficiency and efficiency. However, the overpractice of skills--students spending time on skills they have already mastered--remains a fundamental challenge for tutoring systems. Previous research has reduced overpractice through the development of better problem selection algorithms and the authoring of focused…

We aimed to investigate the inter- and intra-individual relationships between early adolescents' achievement goals, metacognitive monitoring, and academic outcomes. Korean sixth graders responded to achievement goal questionnaires, solved four quizzes, monitored their own confidence in these four quizzes, and took a final exam. Given the nested…

In this study, we investigated the potential of a hypothesized geometrical measurement learning progression (LP) to examine students' thinking and understanding in this domain.We interviewed 30 third to fifth graders using 3 LP-based cognitive tasks that asked the students to find the length, perimeter, area, surface area, and volume measurement…

Century Analytics, Inc. conducted a rigorous evaluation of Edmentum's Exact Path to estimate the impact of Exact Path use on student achievement in mathematics in kindergarten through Grade 8. Exact Path is an online educational tool designed to support individualized student instruction. This study's quasi-experimental design (QED), analyses, and…

Mathematical disposition could influence learning and performance, they usually determine how well students motivate themselves and persevere in the face of difficulties, and they influence the choices-making about coursework, and even educational and career paths. The aim of this study is to investigate the same students' mathematical disposition…
