Spatial Reasoning And Understanding The Particulate Nature Of Matter: A Middle School Perspective, Merryn L. Cole Jan 2017

Spatial Reasoning And Understanding The Particulate Nature Of Matter: A Middle School Perspective, Merryn L. Cole

Theses and Dissertations--Education Science

This dissertation employed a mixed-methods approach to examine the relationship between spatial reasoning ability and understanding of chemistry content for both middle school students and their science teachers. Spatial reasoning has been linked to success in learning STEM subjects (Wai, Lubinski, & Benbow, 2009). Previous studies have shown a correlation between understanding of chemistry content and spatial reasoning ability (e.g., Pribyl & Bodner, 1987; Wu & Shah, 2003: Stieff, 2013), raising the importance of developing the spatial reasoning ability of both teachers and students.

Few studies examine middle school students’ or in-service middle school teachers’ understanding of chemistry concepts or its relation to spatial reasoning ability. The first paper in this dissertation addresses the quantitative relationship between mental rotation, a type of spatial reasoning ability, and understanding a fundamental concept in chemistry, the particulate nature of matter. The data showed a significant, positive correlation between scores on the Purdue Spatial Visualization Test of Rotations (PSVT; Bodner & Guay, 1997) and the Particulate Nature of Matter Assessment (ParNoMA; Yezierski, 2003) for middle school students prior to and after chemistry instruction. A significant difference in spatial ability among students choosing different answer choices on ParNoMA questions was also found. The second paper examined the ways in which students of different spatial abilities talked about matter and chemicals differently.

Students with higher spatial ability tended to provide ...


One-To-One Ipad Technology In The Middle School Mathematics And Science Classrooms, Sharon G. Bixler Jan 2016

One-To-One Ipad Technology In The Middle School Mathematics And Science Classrooms, Sharon G. Bixler

Theses and Dissertations--Education Science

Science, technology, engineering, and mathematics (STEM) education has become an emphasized component of PreK-12 education in the United States. The US is struggling to produce enough science, mathematics, and technology experts to meet its national and global needs, and the mean scores of science and mathematics students are not meeting the expected levels desired by our leaders (Hossain & Robinson, 2011). In an effort to improve achievement scores in mathematics and science, school districts must consider many components that can contribute to the development of a classroom where students are engaged and growing academically. Computer technology (CT) for student use is ...


The Effects Of Peer Mediated Instruction To Teach Math Skills To Middle School Students, Ellen S. Bloyd Jan 2015

The Effects Of Peer Mediated Instruction To Teach Math Skills To Middle School Students, Ellen S. Bloyd

Theses and Dissertations--Early Childhood, Special Education, and Rehabilitation Counseling

The purpose of this study was to determine if there was a functional relation between a peer-delivered modified system of least prompts procedure (SLP) and an increase in level and trend of performance on finding the area of polygons or finding the volume of cylinders, spheres, and cones, and could the peer tutor reliably implement the modified SLP procedure with middle school students with mild to severe disabilities. A multiple probe days across participants design was used. Results from this study show that there was a functional relation across students in which students were able to make progress on academic ...
