The purpose of this study was to explore the effect of visually assisted guided discovery learning strategy on grade 10 students' problem solving skills of learning plane geometry in Woldia City, North Wollo, and Ethiopia. A nonequivalent quasi-experimental pretest-posttest-control group design and a case study design were used. The population of…

Finding teaching methods that foster students' development of geometric thinking and visualization skills is still a current challenge. This study analyses the effects of the combined use of paper folding and dynamic geometry on high school students' geometric thinking and visualization skills. A quasi-experimental study pretest/post-test design…

Science, technology, engineering, and mathematics (STEM) approach and project-based learning (PBL) can be integrated as complementary teaching method to actively engage students in addressing authentic challenges within an educational setting. This study aimed at developing students' skills as they work on their practical projects and at…

Learning geometry with conceptual understanding requires the implementation of appropriate methods that actively engage students and support them in becoming autonomous, critical thinkers, and self-directed learners. The purpose of the study was to investigate the effect of GeoGebra-supported learning on grade ten students' conceptual…

The purpose of this two-experiment study was to examine the effectiveness of an online, synchronous video modeling multicomponent intervention (guided practice, self-monitoring checklist, and prompting) when teaching secondary level mathematical and geometry skills to an autistic high school student. We used a multiple probe baseline across…

The purpose of this action research study was to evaluate the implementation of an adaptive web-based learning environment to personalize geometry instruction and practice for high school students at a private school in North Carolina. This study was guided by the following three research questions: How and to what extent does implementing…

In response to the underrepresentation of minoritized groups employed in the computer science (CS) field, this study aims to enhance underrepresented minoritized (URM) students' motivation for CS through an intervention informed by culturally relevant pedagogy theory in a required high school mathematics course. This intervention integrated…

We show how we used a national distribution of responses from 416 practicing teachers to items of a test of mathematical knowledge for teaching geometry to estimate changes in knowledge by a group of 11 practicing teachers who participated in a 2-year practice-based professional development programme. To draw a reliable interpretation of the…

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…

Learning content in mathematics, such as vector geometry, is still predominantly taught in an abstract manner, as the visualization and interaction of three-dimensional problems are limited with classical forms of teaching such as blackboard lessons or exercise sheets. This research article proposes the use of augmented reality (AR) in mathematics…

This study investigated how the use of structured participation, specifically group presentation roles, supported more equitable participation in doing and learning mathematics. We analyzed videos of two lessons focused on radius, diameter, circumference, and area of circles in which students worked in small groups in a STEM project-based geometry…

A growing body of research suggests that interventions promoting students' utility value for a subject can improve their academic outcomes. However, numerous questions remain regarding how much to adapt prior intervention materials to promote utility value in new educational contexts and how implementation constraints of an educational context may…

The Rural Math Innovation Network (RMIN) is a 4-year project that launched in January 2017 after receiving a $2.9 million Investing in Innovation (i3) development grant from the U.S. Department of Education (ED) and matching funds from the private sector. Virginia Ed Strategies and rural local education agencies (LEAs) in Virginia are implementing…

In response to the glaring disparities in the number of African-Americans, Hispanics, Native Americans, and females employed in computer science (CS) field, the purpose of this study was to enhance underrepresented minority (URM) students' identification with and motivation for CS through a culturally relevant intervention in a required high…
