Western Illinois University in Macomb, Illinois. The project began in September 2004. EC-TIIS 3's goals were four-fold: (1) to test the effects of EC-TIIS' online training developed during EC-TIIS Phase 1 and tested and refined during Phase 2 on a diverse audience in large, complex settings, ultimately providing a teaching/learning community web site easy for families and educators to access and use; (2) to improve access to functional use of technologies in developmentally appropriate curriculum targeting young children with disabilities and their families; (3) to determine the effects of strategies to increase the quantity and quality of webbased training and data collection; and (4) to further refine EC-TIIS usability, to advance the availability, quality, and use of technology in addressing the practical problem of improving online education. The EC-TIIS site is a unique teaching/learning website that combines training content from the Center's tested and effective early childhood technologyrelated projects into a series of nine workshops designed to provide technology knowledge and skills. EC-TIIS 3 was designed to further test and confirm Phase 2 results on the website's feasibility as a training tool for adults to improve the educational results of young children from 3 to 8 with disabilities by providing them with the means to access and participate in the general curriculum.EC-TIIS 3 research design consisted of three related multistrand mixed model studies.Study 1, which included early childhood educators and families, was designed to make comparisons to EC-TIIS 2 findings; to determine the effectiveness of the workshops on a large number of diverse users; and to answer exploratory research questions related to website use and other factors. Study 2, which included early childhood educators who completed at least three online workshops and families who completed at least one workshop, was designed to confirm, extend, and compare findings of Study 1. Study 3, which included university and community college faculty and students, was designed to explore, confirm, extend, and compare findings related to use of the workshops as a supplement to university and community college courses and as a stand-alone graduate course. EC-TIIS 3 Final Report 2 EC-TIIS 3 participants consisted of educators and support staff from early childhood and early childhood special education programs; families of children with disabilities and at risk in early childhood programs; and faculty and students in Early Childhood, Special Education, and Instructional Technology programs at universities and community colleges. During the project's funding period, 1634 individuals from 48 states and 2 territories of the United States, and 42 other countries registered on EC-TIIS website.Quantitative and qualitative data were collected through online surveys and assessments available at the website. Additional qualitative data were collected through questionnaires sent by e-mail to educators, families, and faculty or by d...
