Although it is clearly established that an effective instructional systems design (ISD) process requires evaluation, previous studies provide evidence to show that everyday practices of instructional designers do not include sufficient or appropriate evaluation. Research suggests that organizational barriers and lack of support for evaluation are a leading cause of its inadequate usage. Without appropriate and sufficient evaluation practices, it is impossible to maintain the integrity of the systematic quality of ISD and threatens to undermine the entire concept of instructional design. This article first examines the purposes and importance of evaluation. Second, it reviews research that describes the less‐than‐optimal performance of practitioners as it relates to conducting evaluation, along with identifying causes for this performance deficiency. Third, it proposes using a model of human performance technology for improving the environment leading to implementation of evaluation. 相似文献

Early intervention is a systematic approach for identifying and co-ordinating support for children up to five years of age with developmental delay. The increasing number of children needing early intervention is leading to longer waiting lists for assessment, treatment and diagnosis. Through a mixed-methods approach, this study examined the impact of waiting lists on parental self-efficacy (PSE). An online survey was completed by 197 mothers of children with special educational needs aged one to seven years. Six mothers later took part semi-structured interviews. The research aimed to establish (a) whether there was a relationship between length of time on waiting lists and PSE, and (b) whether there were specific themes or patterns associated with delayed early intervention and PSE. Results showed no significant relationship between time spent on a waiting list and perceived PSE. The qualitative results, however, found that limited contact and poor quality of interactions alongside a lack of information did reduce perceived PSE. 相似文献
