Background. Autism spectrum disorder (ASD) is characterized by impairments in social-communicative deficits and restricted and repetitive behaviors, interests, or activities (APA, 2013). While current estimates suggest 1 in 68 children are diagnosed with ASD, more alarming statistics indicate 1 in 50 school-aged children live with the disorder (Blumberg, Bramlett, Kogan,...
Early childhood is a crucial time for the holistic development of a child’s social, emotional, cognitive, and physical needs to build a solid and broad foundation for lifelong wellbeing and learning (Irwin et al., 2007). During this critical period, there is an increased demand for motor skills and executive function...

Early childhood is a crucial time for the holistic development of a
Background: Early childhood is filled with incredible growth in all areas of development and offers a critical period for optimal learning (Lerner, 2002). During this critical period both motor skills (Bouffard, Watkinson, Thompson, Causgrove Dunn, & Romanow, 1996; Clark & Metcalfe, 2002; Lubans, Morgan, Cliff, Barnett, & Okely, 2010; Stodden...
In 2022, the Report Card on Physical Activity for Children and Youth noted only 24% of children ages 6 to 17 years achieved the recommended 60 minutes of physical activity daily, with a drop in physical activity as children age (Barriss, 2022). More importantly, children with disabilities have been found...
Young children with developmental disabilities (< 12 years old) participate less in physical activity (PA) and experience motor skill deficits compared to young children without disabilities (Jung, Leung, Schram, & Yun, 2018; Liu, Hamilton, Davis, & ElGarhy, 2014; Whyatt & Craig, 2012). When taking account of a bi-directional relationship between...

Students with disabilities are not being afforded the same access to sporting opportunities as their peers without disabilities. The purpose of this dissertation was to build on a foundation of information regarding collegiate adaptive sports through a Critical Disabilities Studies lens. Specific aims included: (1) identifying and describing intercollegiate, adaptive...
The purpose of the study was to analyze and compare the teaching
styles of a trial group of junior secondary science teachers
trained to use and using new materials, and a control group of teachers
using traditional materials. The new materials consisted of portable
science kits, demonstration apparatus, teacher's guides,...
The importance of physical activity is well documented (Haskell et al., 2009a; McReynolds & Rossen, 2004; Steinbeck, 2001). Despite physical activity’s benefits, many individuals are not meeting current weekly physical activity guidelines recommending ≥ 150 minutes of moderate or ≥ 75 minutes of vigorous aerobic physical activity and 2 or...
Polygalacturonase produced by Fusarium oxysporum f. sp.
lycopersici was purified by chromatography on DEAE cellulose, CM
cellulose, and hydroxylapatite. Removal of large amounts of carbohydrate
by chromatography on hydroxylapatite did not affect heat
stability of the enzyme. A large proportion of the remaining carbohydrate
appeared to be covalently linked to...
