Early College High School Model

9th Grade, 10th Grade, 11th Grade, 12th Grade

Early College High Schools are small schools located primarily on community college or university campuses that blur the line between high school and college. The model targets students who are underrepresented in college—including first-generation college-goers, low-income students, and racial/ethnic minorities. Students take a college preparatory curriculum and begin taking college courses as early as 9th grade, with the goal of earning both a high school diploma and up to two years of transferable college credit (or an associate degree) by graduation. Most early colleges are five-year programs. The model emphasizes personalized support, rigorous instruction aligned with college-level thinking, explicit college admissions and financial aid guidance, and a college-going culture. Students are physically located on college campuses to directly experience the college environment while still in high school.

Live Versus Audio-Recorded Narrative Stimuli Intervention

Kindergarten, 2nd Grade, 4th Grade

This study examines whether different methods of presenting narrative stimuli (live reading by assessors versus audio-recorded stories) influence young children's narrative comprehension and oral-retell quality. Children in kindergarten, second grade, and fourth grade were matched on oral language comprehension ability and randomly assigned to either hear stories read aloud live by assessors or listen to audio-recorded stories via CD player. After hearing stories, children were asked to retell them and answer comprehension questions. The intervention involves presenting three narrative stories (from Test of Narrative Language Tasks 1, 3, and 5) using either live or audio-recorded delivery methods.

NumberShire Level 1 Gaming Intervention

1st Grade

NumberShire Level 1 Gaming Intervention (NS1) is a game-based, Tier 2 mathematics intervention designed for first-grade students with or at risk for mathematics difficulties. The intervention targets whole-number concepts and skills across three Common Core State Standards domains: Counting and Cardinality, Number and Operations in Base Ten, and Operations and Algebraic Thinking. NS1 consists of 48 sessions organized into 12 weeks of instruction, with four 15-minute sessions per week, totaling 12 hours of individualized instructional gameplay. The intervention is delivered individually through a gaming platform in school computer labs, facilitated by trained instructional assistants. Each session includes four activities: Warm-Up (practice of previously mastered skills), Teaching Event (explicit instruction on new concepts with demonstrations and guided practice), Assessment Event (extended practice of previously taught skills), and Wrap-Up (review activities). NS1 employs explicit instructional design principles including instructional scaffolding, frequent practice opportunities with immediate feedback, and a Differentiated Learning Pathway that adjusts instruction based on student performance metrics. The intervention uses virtual mathematical representations, NS1 characters for modeling, and a Renaissance-style fairy tale village setting to engage students. Interventionists receive four hours of professional development training before implementation.

Collaborative Intelligent Tutoring System for Fractions

4th Grade, 5th Grade

The Collaborative Intelligent Tutoring System for Fractions is an ITS designed to support elementary school students (4th and 5th grade) learning fractions through either individual or collaborative work. The system covers seven fractions units: naming, making, equivalent, least common denominator, comparing, adding, and subtracting fractions. Each unit contains eight problems using graphical representations (circles, rectangles, and number lines). The intervention offers two versions: a conceptually-oriented tutor that guides students to identify patterns and generalize fraction concepts, and a procedurally-oriented tutor that walks students through step-by-step problem-solving procedures. The collaborative version uses embedded collaborative scripts with distributed responsibility, where students sit at separate computers with shared but differentiated problem views and communicate through speech. Students work synchronously with networked collaboration. The system provides cognitive support through step-by-step guidance, immediate feedback, and on-demand hints. The study ran across five 45-minute class periods, with students working in pairs (for collaborative conditions) or individually throughout all sessions.

Dual-Language Immersion Programs

Prekindergarten, Kindergarten, 1st Grade, 2nd Grade, 3rd Grade, 4th Grade, 5th Grade, 6th Grade, 7th Grade, 8th Grade

Dual-language immersion programs provide native English speakers and English learners with general academic instruction in two languages (Spanish, Mandarin, Japanese, or Russian) from kindergarten onward. The programs follow either a 90/10 two-way model (where 90% of instruction in kindergarten is in the partner language, declining by 10 percentage points per grade, serving approximately half native speakers of each language) or a 50/50 one-way model (where 50% of instruction in each core subject occurs in the partner language throughout elementary grades, primarily serving native English speakers). In grades K-3 of two-way programs, students receive 75%-100% of mathematics, 56%-100% of language arts, and 100% of science and social studies instruction in the partner language. In grades 4-5, they receive about 25% of mathematics, 58% of language arts, and 100% of science and social studies in the partner language. Middle school students take one language arts class in English, one in the partner language, and one social studies class in the partner language. Students are admitted through a district-administered lottery process.

Passport to Literacy

4th Grade

Passport to Literacy is a widely-used, supplemental multi-component reading intervention program designed to improve reading outcomes for struggling readers in fourth grade. The program provides daily 30-minute sessions in small groups of 4-7 students throughout the school year (120 lessons total). Passport to Literacy addresses phonics and word recognition, fluency, vocabulary, and comprehension in each lesson, with main emphasis on strategies for gaining understanding, building conceptual and background knowledge, and teaching students to interact with text to gain meaning and monitor comprehension. Lessons are organized into 12 ten-day adventures. Each lesson includes Word Works (focusing on advanced word study, affixes, roots, and multi-syllabic word strategies) and Read to Understand (organized into before, during, and after reading comprehension skills and strategies). The program requires research staff or trained interventionists to deliver instruction. Prior to intervention, teachers participated in approximately 8 hours of training over two days, with ongoing twice-monthly coaching visits and monthly meetings throughout implementation.

Early College High School Initiative (ECHSI)

9th Grade, 10th Grade, 11th Grade, 12th Grade

The Early College High School Initiative (ECHSI) provides underserved students with exposure to and support in college while they are in high school. Early Colleges partner with colleges and universities to offer all students an opportunity to earn an associate's degree or up to two years of college credits toward a bachelor's degree during high school at no or low cost to the students. The intervention serves students in grades 9-12, with most Early Colleges located on college campuses. Early Colleges provide a variety of supports including tutoring, advisories, college preparatory information, and academic support classes. The program integrates rigorous high school curriculum with college coursework, with students typically starting college courses in ninth grade. Seven of the ten study Early Colleges had course sequences allowing students to earn at least two years of college credit. The underlying assumption is that engaging underrepresented students in rigorous curriculum tied to earning college credits will motivate them and increase their access to postsecondary education and credentials after high school.

Highly and Minimally Guided Discovery Instruction for Basic Add-1 and Doubles Combinations

Kindergarten, 1st Grade, 2nd Grade

This study evaluated computer-based interventions designed to promote fluency with basic addition combinations (add-1 and doubles) among kindergarten through second-grade students. The interventions used either highly guided discovery learning (which sequentially arranged problems to highlight patterns and provided explanatory feedback) or minimally guided practice (semi-random practice with feedback on correctness only). The highly guided add-1 training connected adding 1 to number-after relations, while the highly guided doubles training connected doubles to everyday analogies and even numbers. Students participated in two 30-minute computer sessions per week over approximately 9 months. The interventions included preparatory training (7 sessions on concrete counting strategies and 8 sessions on estimation) followed by three stages of primary training focused on strategy discovery, practice, and fluency development. All training was delivered one-on-one at computer stations outside classrooms.
