Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Investigators will work with research practice partners Lane Educational Services District (ESD) to disseminate bilingual electronic and printed recruitment materials to Latinx families in the elementary and middle schools throughout the 16 school districts in Lane County, OR. Recruitment materials will direct families to contact the project's bilingual staff by phone to receive study details and, following a brief screen, to engage in an informed consent process. 300 eligible Latinx English-learner parent/student dyads will be recruited. Students will be in grade 4-8; families will speak primarily Spanish in the home; and families will have a smartphone, tablet, or computer and Internet access at home.

The Investigators will administer the pre-test to all 300 parent/student dyads via Qualtrics and randomize 150 parent/student dyads to the TSF treatment, 150 parent/student dyads to the treatment-as-usual control condition. Each family will be assigned a non-identifiable user name linked only to their non-identifiable participant ID. The Investigators will then send the TSF program materials and links to the treatment group. These materials will include graphic and video tutorials on TSF set-up and use, including set-up of a wireless bridge that allows researchers to monitor the non-identifiable program usage. Bilingual telephone support will be provided during the 1-month set-up period and throughout the 24-week TSF intervention period. During the intervention, families in the treatment group will be asked to use TSF for 24 weeks. During that time, they will receive 3 notifications/week that prompt them to engage in program games and activities targeting 72 scientific academic vocabulary (SAV) words.

Half way through the 24-week intervention period, the Investigators will administer the mid-test via Qualtrics to all 300 parent/student dyads and following the 24-week intervention, the Investigators will administer the post-test via Qualtrics to all 300 parent/student dyads. Pre-, mid-, and post-test surveys will measure gains in knowledge and usage of the 72 SAV words TSF targets, academic self-efficacy, and academic enabling behaviors. Treatment group dyads will also complete a usability, technology acceptance, and consumer satisfaction survey at post-test. All 300 parent/student dyads will receive a smart speaker at pretest, and $100 at mid-test and post-test.

Following post-test, parent/student dyads in the treatment-as-usual control condition will receive TSF program materials.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental: Intervention

Parent/student/dyads in the treatment condition will be sent program materials via mail and text or email, including smart-speaker hardware, wireless network bridges for wireless network connectivity, and web links to Talk STEM Familia, including set-up video tutorials, and graphic instructions. Intervention activities will take place in participants' homes over the 24-week intervention period and will include using the dual-language Talk STEM Familia technology to receive instruction, practice, and feedback on academic vocabulary.

Group Type EXPERIMENTAL

Talk STEM Familia Treatment Condition

Intervention Type OTHER

This study has one intervention and two arms: experimental and treatment as usual. Participants randomized to the treatment condition will receive the TSF technology in addition to the vocabulary instruction, monitoring, or resources delivered by English Language Development programs (ELD) and schools. TSF will deliver frequent, brief, dual-language exercises to help families learn, practice and apply SAV words in conversation. Audio-visual lessons will support learning at all literacy levels, regardless of prior familiarity with STEM subjects. The complete TSF tool will contain approximately 72 minutes of video modeling and 12 hours of interactive exercises delivered over 24-weeks in brief, interactive, easy to assimilate lessons.

Treatment as usual

Parent/student dyads in this arm will receive treatment-as-usual (the vocabulary instruction regularly provided in their schools). They will receive the TSF technology after post-test data has been collected.

Group Type NO_INTERVENTION

No interventions assigned to this group
