Induction Of Special Education Teachers In Self-Contained Classrooms For Students With Autism, Nelly A. Dixon

Walden Dissertations and Doctoral Studies

Over the past decade, the number of students with autism spectrum disorders (ASD) in public schools in a northeastern US state has almost tripled in number. Given a lack of preservice training on autism topics, many beginning special education teachers are ill prepared to meet the challenges of working in classrooms for students with ASD and current induction practices do not specifically support special education teachers.

Transcending Technological Innovation: The Impact Of Acquisitions On Entrepreneurial Technical Organizations, Bruce Crochetiere

Walden Dissertations and Doctoral Studies

Technology firms with substantial cash reserves acquire smaller entrepreneurial firms for diversification. In 2006, 3 large firms acquired 28 organizations, with the combined deals exceeding {dollar}4.7 billion. The problem addressed in this study is that new start-up companies with innovative ideas may not mature when they are acquired by larger companies and do not fully articulate potential industry-transcending innovation. This is important because the unsuccessful integration of an acquisition can dismantle innovation and compromises economic inventiveness. Drawing from the disruptive innovation and the resource-based theories, the purpose of the quasi-experimental study was to examine the impact of acquisition by larger …

The Effects Of School Home Communication And Reading Fluency In Kindergarten Children, Farjana Khan Jan 2011

The Effects Of School Home Communication And Reading Fluency In Kindergarten Children, Farjana Khan

Walden Dissertations and Doctoral Studies

Many researchers have documented that reading fluency scores continue to be a national concern for the United States and have suggested that early reading failure has long-term detrimental effects on society. However, much less is known regarding specific interventions that could reduce this concern. Investigators in other studies have suggested the development of early school-home partnerships to improve reading scores. The purpose of this quasi-experimental study was to evaluate the effectiveness of a systematic school-home intervention to improve reading fluency scores. Following the theoretical foundation of emergent literacy theory and Joyce Epstein's framework, the research question focuses on the association …

Preschoolers' Use Of Technology In The Classroom, Re, Darlene M. Estes-Del Re Jan 2011

Preschoolers' Use Of Technology In The Classroom, Re, Darlene M. Estes-Del Re

Walden Dissertations and Doctoral Studies

Almost from birth, children are immersed in a technologically rich world yet they often enter preschools that offer little to no use of technology. Preschool learning is tied to more traditional forms of reading and writing; this may be inconsistent with the ways children are learning at home and will learn in elementary school. Despite growing interest in creating learning environments that better mirror the technological experiences of the home, there is a significant gap in current research about how learning is affected in preschool environments designed with multiple forms of technology. This qualitative single case study was designed to …

Institutionalized Community College Service Learning To Promote Engagement, Velda Arnaud

Walden Dissertations and Doctoral Studies

Community college graduation rates are low, and community colleges have been tasked with producing more graduates to meet workforce needs. Research has determined that engaged students remain at their institutions and complete their degrees.
