Emphasizes the importance of collecting data on the prevalence of specific communication disorders in children and data on both the short-term and long-term impact of speech/language interventions in the schools. (Author/DB)

Based on the premise that Canada needs to collect, collate, analyze, and disseminate reliable data on early childhood education and care (ECEC) programs that are comparable across provinces/territories and that good data are fundamental for informing policy, research, and service delivery, the National Data Project was funded in 2000-2001 to…

Purpose: This study seeks to explore the utilization of mobile phone services in the educational environment, explore the nature of mobile phone use among university students, and investigate the perception of university students on mobile phone uses in library and information services. Design/methodology/approach: The study used a review of…

This paper presents criteria for establishing the trustworthiness of naturalistic inquiries, and specific techniques to facilitate their achievement or determine the degree of their achievement. The following criteria are briefly described: fairness; and ontological, educative, catalytic and tactical authenticity. Explored in greater detail,…
