Number Line Approach Combined With Cognitive Learning Strategies

6th Grade

This intervention uses a number line-centered approach combined with cognitive learning strategies to teach fraction concepts to sixth graders struggling with mathematics. Delivered in small groups of 3-4 students, the intervention consists of 27 lessons over 6 weeks (approximately 45 minutes per lesson, totaling about 20.25 hours). Each lesson includes warm-up practice, multiplication fact practice, counting fractions aloud, 15-20 minutes of explicit instruction focused on the number line, fast-paced card games for fraction magnitude practice, and independent cool-down worksheets. The intervention covers halves, fourths, eighths, thirds, sixths, and twelfths, teaching students to partition number lines, locate fractions, understand equivalencies, compare magnitudes, and perform basic operations. Instruction incorporates explicit teaching, representational gestures, dual coding (visual and verbal), spaced and interleaved practice, and immediate feedback. Trained research assistants deliver the intervention, requiring prior training (16+ hours) on gestures, feedback strategies, and behavior management.

Relational Scaffolding

3rd Grade

Relational Scaffolding is an instructional approach that enhances children's understanding of scientific models through systematic, guided comparisons between observable phenomena and corresponding modeled events. Designed for 3rd-grade students learning about the day-night cycle, the intervention uses split-screen video footage showing both Earth-based observations (e.g., sunrise, sunset) and space-based models of Earth rotation simultaneously. A trained researcher guides students through these videos, pointing at and between perspectives to clarify temporal, spatial, and causal correspondences. The intervention progresses from an embodied simulation where students physically enact Earth's rotation, to relational scaffolding using video of their embodied experience, then to a 3D physical model simulation, and finally to relational scaffolding comparing both simulations. Sessions last 20-30 minutes each, delivered one-on-one in a quiet room at the student's school during after-school hours, twice weekly for three weeks (total of 5 instructional sessions). The approach requires video recording equipment (GoPro camera, tripod, videorecorder), video editing capabilities, a computer for displaying split-screen videos, and physical materials including a 3D Earth-Sun model. One trained researcher delivers the intervention to one student at a time.

Arts Access Initiative (AAI) is a school-community partnership program that provides substantial increases in arts educational experiences to elementary and middle school students in Houston Independent School District. The program serves students in grades 3-8, particularly those in schools with the lowest levels of arts resources. AAI provides arts experiences through teaching-artist residencies (33% of experiences), in-school professional artist performances (31%), field trips to cultural institutions (27%), and afterschool programs (9%). The arts disciplines include theatre (54% of experiences), music (18%), visual arts (16%), and dance (12%). Schools commit to a monetary match ($1-$10 per student), which is matched 1:1 by the Houston Endowment, resulting in an average annual budget of $14.67 per student. Participating schools must designate a campus arts liaison, engage in strategic arts planning, participate in teacher and principal arts-integration professional development, and attend peer-network mentoring sessions. The AAI director and staff work with principals to select diverse arts programs aligned with school goals.

English Language and Literacy Acquisition-Validation (ELLA-V)

Kindergarten, 1st Grade, 2nd Grade, 3rd Grade

ELLA-V is a professional development and instructional support program designed for K-3 teachers of English learners (ELs) in Texas. The program provides bimonthly virtual professional development sessions (18 sessions from September to May, approximately 90 minutes each), virtual mentoring and coaching (up to three observation rounds with feedback between January and May), and EL-relevant curricula materials aligned with content-area standards. The intervention was implemented with a backwards design across four school years: grade 3 in 2013-14, grade 2 in 2014-15, grade 1 in 2015-16, and kindergarten in 2016-17. Teachers received the intervention for a single year dependent on grade-level implementation. The program focuses on literacy and science content, as well as cognitive-academic language proficiency to enhance EL students' English language acquisition. Two treatment conditions (Treatment 1 and Treatment 2) received equivalent professional development and coaching, but curricula materials differed across treatments and grade levels according to student development. Treatment 1 curricula focused on oral language and phonemic awareness in grade K, oral language and learning to read in grade 1, learning to read in grade 2, and reading to learn (content-area reading) in grade 3. Treatment 2 curricula largely focused on students' oral language development across all grades, with a writing component added in grades 2-3.

Making Online Decisions (MOD) System

Infant/Toddler

The Making Online Decisions (MOD) system is an adaptive intervention that guides early educators' data-based intervention decision making for infants and toddlers at risk for language delay. The MOD is a web-based tool used by home visitors (HVs) in Early Head Start programs to support parent-mediated language promotion interventions. When a child scores at least 1 SD below benchmark on the Early Communication Indicator (ECI), the MOD automatically provides guidance through five steps: (1) validating the low score, (2) identifying potential causes, (3) recommending PC TALK language strategies based on the child's ECI performance, (4) documenting implementation through fidelity checklists, and (5) analyzing the child's progress after three follow-up ECIs. HVs use the MOD to select appropriate PC TALK strategies to share with parents, print strategy materials, and monitor children's communication growth over time. The system requires HVs to be trained and certified in administering the ECI and trained in using both the PC TALK intervention strategies and the MOD system itself.
