This study carries forward the exploration of joint attention engagement in children from 18 to 24 months of age enrolled in 'low-quality' childcare centers. Childcare providers and children were videotaped to capture social interactions in the classroom including duration and bids for joint attention. One-half of 48 childcare providers were randomly assigned to receive professional development training (PDT) (the Focus-Follow-Talk ® technique) designed to increase the frequency of joint attention. Three months after the PDT and three coaching visits for each subject in the treatment group, 30 minutes of videotape was recorded and coded for each childcare provider in the treatment and control groups. Significant findings were reported for the trained childcare providers on joint attention engagement duration and total bids for joint attention engagement. There was also evidence supportive of joint attention subtypes.
This study examined effects of professional development for child-care staff on language acquisition of children ages 14-36 months. Child-care staff from 44 child-care centres agreed to participate in the study. Child-care staff from one-half of the child-care centres were randomly assigned to a onetime, four-hour workshop followed by three classroom visits over the subsequent three months. This treatment was designed to increase frequency and quality of joint attention episodes between the child-care staff and the toddlers. Child-care staff from the remaining 22 centres were assigned to a wait-list control group. Toddlers (N = 121) in both the groups (n treatment = 64; n control = 57) were assessed with a measure of language acquisition after six months. While there were no significant differences on total language acquisition between groups, treatment group toddlers whose child-care providers engaged in more frequent and longer bouts of joint attention acquired more language. The results of this study support that when child-care staff engage in longer and higher quality bouts of joint attention with toddlers they can affect language acquisition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
