Alves, Francisco Régis Vieira; De Sousa, Renata Teófilo; Fontenele, Francisca Cláudia Fernandes – Acta Didactica Napocensia, 2022
This article presents a didactic situation focused on geometric reasoning using 3D GeoGebra, using the concepts Theory of Didactical Situations (TDS). The objective of this work is to bring a didactic proposal for the teaching of Spatial Geometry, working with the students' geometric perception, oriented and elaborated based on the dialectic of…

Choo, Sam; Park, Sunhi; Nelson, Nancy J. – Learning Disability Quarterly, 2021
Science, Technology, Engineering, and Mathematics (STEM) education initiatives have placed pressure on teachers to bring technology tools into classroom, including three-dimensional (3D) printing. Yet, little research has examined what specific math skills are required for 3D printing technology. This article describes a follow-up analysis of…

Kotsopoulos, Donna; Makosz, Samantha; Zambrzycka, Joanna; Cordy, Michelle – School Science and Mathematics, 2018
International standardized tests are showing an underperformance of students in geometry and spatial ability relative to other content domains. In this research, we examined the relationship between a teacher's judgment of third- and fourth-grade students' geometry and spatial ability (i.e., grades), three spatial ability tasks (Water-Level-Task,…

Zhang, Dake – Learning Disabilities: A Contemporary Journal, 2017
We examined the effectiveness of (a) a working memory (WM) training program and (b) a combination program involving both WM training and direct instruction for students with geometry difficulties (GD). Four students with GD participated. A multiple-baseline design across participants was employed. During the Phase 1, students received six sessions…

Walcott, Crystal; Mohr, Doris; Kastberg, Signe E. – Journal of Mathematical Behavior, 2009
In this study, we examine a large set of student responses to a constructed-response geometry item on the National Assessment of Educational Progress (NAEP) administered in 1992 and 1996. The item asks students to name the similarities and differences between a parallelogram and a rectangle of equal area presented side by side on a grid. Through…

Reese, Clyde M.; Jerry, Laura; Ballator, Nada – 1997
The National Assessment of Educational Progress (NAEP) is the only nationally representative and continuing assessment of what students in the United States know and can do in various academic subjects. The 1996 NAEP in mathematics assessed the current level of mathematical achievement as a mechanism for informing education reform. In 1996, 44…
