About this trial
The purpose of this study is to determine whether Spanish-speaking caregivers can learn to teach science vocabulary to their children with the use and educational app and a short training video with target words. The children will take language, speech, and hearing tests, as well as science and vocabulary pretests with a speech-language pathologist. You will be asked to answer some questions about your language use in the house and other places. If you and your child qualify for the study, the researcher will randomly place you a group to 1) use the app, or 2) use books. Since you are chosen at random, there is no way of knowing which group you and your child will be in before you start. Participants will take part in an 11-week study (3 weeks of testing at the beginning, middle, and end of study, and 8 weeks of intervention). The testing will be conducted in a place that is comfortable for your child (home, school, university clinic). The intervention can be done at home (researchers will not be present for this part of the study, but we will be available to support you or answer questions). We want you to play (group 1) or read (group 2) with your child two times a week (\~30 minutes) and send the audio recording of your interaction to our researchers.

Treatments tested in this trial
Robust vocabulary intervention
BehavioralCaregivers will be trained to teach target vocabulary to their children
Treatment groups
Trial outcomes
Primary outcomes
Caregiver fidelity
Caregivers will use target vocabulary words a specified number of times during science activity with their child, as measured by review of audio recorded sessions.
Improved Tier-2 vocabulary for children
Children will be tested at baseline, mid intervention, and post intervention to determine if target vocabulary words were learned during caregiver provided intervention.
Modify intervention and training
Barriers and facilitators of teaching caregivers robust vocabulary intervention will be recorded and coded from caregiver focus group responses.
