Trial Outcomes & Findings for Talk STEM Familia: Dual-Language (TSFII) (NCT NCT04896229)
NCT ID: NCT04896229
Last Updated: 2025-05-29
Results Overview
AVM (Academic Vocabulary Meaning) will measure change in student vocabulary knowledge (multiple choice test of meaning). The multiple choice test is based on the assessment used in Beck et al. (1982) and McKeown et al. (1983) with middle school students. Scores were computed as the total percentage of vocabulary words correctly identified out of 72. Score could range from 0 to 100 and higher scores indicate greater levels of vocabulary knowledge.

Participant Flow
We enrolled 400 participants, however, only 168 parents and student dyads (N = 336) were randomized to the study. The remaining 64 participants were part of the formative research and were never meant to be part of the randomized study. In the Protocol Enrollment, the Number Started and Number Completed reflect dyads. See the Milestones for specificity at the parent and youth levels.

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.
Talk STEM Familia Treatment Condition: 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.

Items were developed using procedures for developing self-efficacy scales (Bandura et al., 2001). Items used a 5-point response option (1 = not at all confident, 5 = extremely confident) and a mean score was computed (alpha = .89) and could range from 1 to 5.

SECONDARY outcome
Timeframe: Baseline, 12 weeks (mid-treatment), and 24 weeks (post-treatment)STEM will measure student interest in choosing STEM careers (4 items). Items were adapted from: the Student Engagement Instrument (SEI; Betts, Appleton, Reschly, et al., 2010) and the Efficacy to Influence School-related Performance subscale of the Parental Self-Efficacy Scale (PSES; Bandura, et al., 2001). Items used a 5-point response option (1 = not at all interested, 5 = extremely interested) and a mean score was computed (alpha = .69) and could range from 1 to 5. Higher scores indicated greater interest using SAV words.

Experimental: Intervention
n=79 Participants
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.
Talk STEM Familia Treatment Condition: 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
n=75 Participants
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.

SECONDARY outcome
Timeframe: Baseline, 12 weeks (mid-treatment), and 24 weeks (post-treatment)AEB will measure parent academic support behaviors (20 items). Efficacy to Influence School-related Performance subscale of the Parental Self-Efficacy Scale (PSES; Bandura, et al., 2001). Items used a 9-point response option (1 = nothing, 9 = a great deal) and a mean score was computed (alpha = .94) and could range from 1 to 9. Higher scores indicated greater efficacy to influence school performance.

Timeframe: Baseline, 12 weeks (mid-treatment), and 24 weeks (post-treatment)ALB will measure student academic learning behaviors (20 items). Items used a 5-point response option (1 = strongly disagree, 5 = strongly agree) and a mean score was computed (alpha = .90) and could range from 1 to 5. Higher scores indicated greater levels of perceived academic learning behaviors.
