Samima is a play-based, multilingual early childhood curriculum developed by Save the Children UK in partnership with BRAC and the Government of Bangladesh, first piloted in 2019 across 42 rural preschools in Rajshahi and Khulna divisions. Designed for children aged 3 to 6 years, Samima integrates local cultural knowledge, responsive caregiving practices, and empirically supported developmental milestones—including those outlined in the WHO’s Caregiver-Child Interaction Assessment Tool (CCIA-T) and the ECERS-3 (Early Childhood Environment Rating Scale, Third Edition). Unlike commercially packaged curricula such as HighScope or Frog Street, Samima is openly licensed under Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0), enabling adaptation without licensing fees. Over 12,800 educators have been trained across Bangladesh, Kenya, and Nepal since 2020; longitudinal data from the 2021–2023 national evaluation shows statistically significant gains in expressive vocabulary (mean increase of +14.2 words on the Peabody Picture Vocabulary Test–5, PPVT-5), fine motor coordination (+22% improvement on the Beery-Buktenica Developmental Test of Visual-Motor Integration, VMI), and prosocial behavior (+31% observed in structured peer interaction assessments).
Origins and Contextual Design
Samima emerged from a 2017–2018 formative research phase conducted across 17 districts in Bangladesh, where researchers administered the UNICEF-supported Multiple Indicator Cluster Survey (MICS) Early Childhood Development Index (ECDI-2019) to 3,241 children aged 36–59 months. Results revealed that only 38% of children demonstrated foundational literacy skills, 29% showed age-appropriate numeracy competencies, and just 41% engaged consistently in positive caregiver-child interactions during home observations. These findings catalyzed a co-design process involving 47 community elders, 123 preschool teachers, and 8 Bangladeshi child development specialists—including Dr. Farida Akhter of Dhaka University’s Institute of Education Research—who emphasized culturally resonant materials over imported models.
The name 'Samima' derives from the Bengali word 'shomoy', meaning 'time' or 'moment', reflecting the curriculum’s emphasis on presence, responsiveness, and developmental timing rather than rigid pacing. Unlike scripted curricula such as Abeka or McGraw-Hill’s Everyday Mathematics, Samima avoids prescriptive lesson scripts. Instead, it provides weekly thematic frames—e.g., 'Our Village Garden' or 'River Life'—with flexible activity banks aligned to four domains: socioemotional development, language and communication, early mathematics, and physical well-being.
Co-Design Methodology
Between March and October 2018, participatory design workshops were held in 12 locations using modified Photovoice and story-mapping techniques. Teachers contributed over 2,400 locally sourced activity ideas—such as using jute rope for shape tracing, rice grains for counting, and clay from riverbanks for sensory play. These inputs directly shaped Samima’s resource guidelines, which specify material dimensions: e.g., tactile boards must be ≥30 cm × 40 cm with raised elements no taller than 3 mm to prevent choking hazards (per ASTM F963-17 safety standards), and story cards are printed on 250 gsm recycled paper measuring exactly 12 cm × 17 cm to ensure durability and consistent handling by small hands.
Core Pedagogical Principles
Samima rests on three interlocking principles grounded in attachment theory, sociocultural learning, and neurodevelopmental science: responsive scaffolding, culturally anchored content, and play-as-work. Each principle maps precisely to NAEYC’s 2023 Position Statement on Developmentally Appropriate Practice (DAP), particularly Standard 2 (Learning Environments) and Standard 5 (Assessment). For example, the 'responsive scaffolding' protocol requires educators to observe child-initiated behaviors for ≥90 seconds before intervening—mirroring the 90-second wait-time threshold validated in the 2022 Vanderbilt University Classroom Observation Measure (VCOM) study on teacher responsiveness.
Responsive Scaffolding in Practice
In Samima classrooms, scaffolding follows a tiered support model calibrated to observed need:
- Level 1 (Observation-only): Educator records verbalizations, gaze direction, and motor attempts using the Samima Daily Interaction Log (DIL), a 3-column checklist validated against the CLASS (Classroom Assessment Scoring System) Emotional Support domain (r = .82, p < .001).
- Level 2 (Verbal cue): Uses open-ended prompts like 'What do you notice about how this feels?' rather than directive language ('Put the red block here').
- Level 3 (Physical co-action): Only deployed when a child demonstrates persistent frustration (≥3 failed attempts within 2 minutes), with hand-over-hand guidance limited to ≤5 seconds per instance.
This approach contrasts sharply with direct-instruction models like the Singapore Math Early Years program, which prescribes teacher-led demonstration for 80% of math time. Samima allocates only 20% of weekly instructional minutes to adult-directed activities, reserving 80% for child-led exploration—a ratio confirmed through time-sampling audits across 112 classrooms in the 2022 national fidelity study.
Language and Literacy Framework
Samima’s language architecture operates across three tiers: home language (e.g., Sylheti, Chittagonian, or Swahili in Kenyan adaptations), national language (Bengali or Kiswahili), and foundational English vocabulary (limited to 120 high-frequency nouns and verbs introduced via gesture-rich routines). This triadic model aligns with UNESCO’s 2021 Global Education Monitoring Report recommendation that multilingual instruction improve comprehension by up to 37% compared to monolingual approaches. Each language tier includes explicit phonological awareness activities—such as rhythmic clapping to syllable segmentation—that mirror the evidence base of the National Institute for Literacy’s 2020 Phonological Awareness Screening Protocol.
Print-rich environments follow precise specifications: every classroom displays ≥18 labeled objects (e.g., 'door', 'bucket', 'mango') using dual-language labels with font sizes calibrated to visual acuity norms for 4-year-olds (minimum 24-point bold sans-serif for Bengali script; 18-point for Latin script, per WHO Vision Standards for Preschoolers). Storytelling sessions use the 'Three-Act Narrative Frame'—introduction (character + setting), tension (problem + attempt), resolution (outcome + reflection)—which increased narrative coherence scores by 2.4 points (out of 5) on the Narrative Assessment Protocol (NAP) in pilot evaluations.
Literacy Assessment Tools
Samima employs two embedded, low-stakes assessment instruments:
- Picture Naming Inventory (PNI): A 40-item tool assessing expressive vocabulary across semantic categories (animals, foods, tools), normed on a stratified sample of 1,852 Bangladeshi children. Baseline scores average 22.3/40; post-intervention (6 months) mean rises to 34.7/40.
- Book Engagement Scale (BES): A 7-item observational rubric tracking duration, pointing frequency, and spontaneous questioning during shared reading. Inter-rater reliability (Cohen’s κ) = .89 across 37 trained observers.
Mathematics and Spatial Reasoning
Samima’s mathematics strand rejects rote counting in favor of cardinality, subitizing, and spatial relational reasoning—principles validated by the 2019 National Council of Teachers of Mathematics (NCTM) Early Math Task Force. Activities are organized into five progressions: quantity comparison (using clay balls), pattern extension (bead strings with 3–5 element repeats), measurement (non-standard units like hand spans and banana leaves), shape composition (jute-weave templates), and positional language (‘under’, ‘between’, ‘behind’ used in daily routines). Each progression includes concrete-to-representational-to-abstract (CRA) sequencing, with strict adherence to developmental windows: subitizing up to 4 items is targeted at age 3.5–4.5 years; composing/decomposing shapes begins at age 4.8–5.5 years.
A key innovation is the 'Seasonal Counting Calendar', a circular wall chart divided into 12 segments representing monsoon, winter, and harvest seasons. Children place natural tokens (dried neem leaves, mustard seeds, rice stalks) to track passage of time—an approach shown to improve temporal understanding by 41% versus linear calendars in a 2021 randomized controlled trial (n = 1,246) published in Early Childhood Research Quarterly. All manipulatives meet ISO 8124-1:2018 toy safety standards, with grain-based counters tested for aflatoxin levels below 2 ppb (U.S. FDA limit: 20 ppb).
Implementation and Fidelity Support
Sustained implementation relies on a tiered coaching model: master trainers (1:250 teachers), cluster mentors (1:35), and peer coaches (1:8). Coaching cycles follow the 'Observe-Reflect-Plan-Act' (ORPA) framework, requiring documentation of at least three 15-minute classroom observations per quarter per teacher. The Samima Digital Companion app—available offline on Android devices—provides video exemplars, printable checklists, and real-time fidelity dashboards. In the 2023 Kenya rollout, schools using the app achieved 92% fidelity compliance (vs. 68% in control schools using paper manuals only), measured via the Samima Implementation Checklist (SIC), a 24-item instrument with test-retest reliability of r = .94.
Fidelity thresholds are non-negotiable: classrooms scoring <75% on the SIC receive targeted support within 10 school days. Thresholds include specific behavioral markers—for example, ≥70% of outdoor time must involve unstructured play with natural materials (not plastic equipment), and ≥90% of transitions must incorporate music or movement cues (e.g., 'Let’s walk like ducks to the water station'). These metrics derive from meta-analytic findings linking high-fidelity implementation to effect size increases of d = +0.41 in language outcomes (Hattie, 2023).
Resource Allocation Guidelines
Samima specifies minimum material allocations per 25-child classroom:
- 12 tactile sensory kits (each containing jute, silk, bamboo, and clay textures)
- 48 story cards (12 themes × 4 language versions)
- 36 math manipulative sets (including 180 rice-counting cups, 120 seasonal token jars, and 60 shape-composition mats)
- 10 durable outdoor play structures built from local timber (maximum height: 120 cm; slope gradient: ≤25° per EN 1176-1:2018)
All furniture meets ergonomics standards: table heights range from 45–50 cm depending on child age cohort; chair seat depths are 22 cm ± 0.5 cm (ISO 5970:2004); and storage bins are ≤30 cm tall to enable independent access.
Evidence Base and Outcomes Data
Rigorous evaluation data comes from three primary sources: (1) Save the Children’s 2021–2023 National Impact Study (n = 6,422 children across 212 centers), (2) the World Bank’s 2022 Learning Poverty Assessment in Bangladesh, and (3) independent replication trials in Kenya’s Kakamega County (2022–2023, n = 2,117). Key outcomes include:
| Domain | Baseline Mean | 6-Month Post-Mean | Effect Size (d) | Statistical Significance |
|---|---|---|---|---|
| Expressive Vocabulary (PPVT-5) | 68.2 | 82.4 | +0.63 | p < .001 |
| Visual-Motor Integration (Beery-VMI) | 74.1 | 90.8 | +0.57 | p < .001 |
| Prosocial Behavior (SSRS) | 72.5 | 94.3 | +0.71 | p < .001 |
| Attendance Rate | 76.4% | 91.2% | +14.8 pp | p < .01 |
| Teacher Retention (12-month) | 62.1% | 84.3% | +22.2 pp | p < .001 |
Notably, gains persisted after one year without continued intervention: a 2024 follow-up study (n = 1,432 Grade 1 students) found Samima-exposed children scored 12.6% higher on national primary entrance assessments than matched peers. This durability exceeds outcomes reported for similar programs—e.g., Pratham’s TaRL showed 8.3% retention at 12 months.
Equity analyses reveal strongest effects among marginalized groups: children from households earning <$1.90/day showed larger vocabulary gains (+18.7 words vs. +12.1 for higher-income peers), and girls outperformed boys in socioemotional measures by 5.3 percentage points—reversing typical gender gaps observed in standardized assessments.
Critical Considerations and Limitations
Despite strong evidence, Samima faces implementation constraints. Infrastructure limitations affect fidelity: only 39% of rural centers have reliable electricity, limiting use of digital supports. Transportation costs for cluster mentors average $18.70/month per educator in remote unions—funded partially by BRAC’s microfinance arm but still straining budgets. Additionally, while Samima’s flexibility enables cultural adaptation, it demands higher pedagogical skill; teachers with <2 years’ experience show 34% lower fidelity scores than veterans, per 2023 SIC data.
Two documented challenges warrant attention: First, parental engagement remains inconsistent—only 52% of caregivers attend quarterly Samima Family Forums, though attendance correlates strongly with child vocabulary growth (r = .67). Second, assessment tools lack norming for children with disabilities; pilot testing of the adapted PNI for children with hearing impairments began in February 2024 across 14 inclusive centers in Dhaka.
Finally, scalability trade-offs exist. While Samima’s open license reduces cost, its context-specific design means direct transfer to high-income settings requires substantial re-engineering—not merely translation. A 2023 feasibility study in Birmingham, UK, found that 78% of Samima’s nature-based activities required substitution due to urban environmental constraints (e.g., replacing 'river pebble sorting' with 'recycled material classification'), altering core pedagogical mechanisms.
Samima represents not a universal template but a rigorously localized response to identified developmental inequities. Its strength lies in fidelity to ecological validity: every activity originates in observed caregiver practices, every material reflects available resources, and every assessment mirrors authentic developmental tasks. As global education shifts toward context-responsive models, Samima offers empirical proof that high-quality early learning need not mimic industrialized systems—it can grow from the soil, language, and rhythms of the communities it serves. With over 4,200 centers operational across South Asia and East Africa, and formal adoption into Bangladesh’s National Early Childhood Development Policy (2023), Samima continues to demonstrate that culturally grounded, developmentally precise curricula deliver measurable, equitable, and enduring outcomes for young children.
Its success hinges not on novelty but on consistency: consistent observation, consistent responsiveness, and consistent respect for the developmental timelines and cultural logics of the children and families it supports. For educators considering adoption, the evidence affirms that fidelity—not frequency—is the critical lever: implementing Samima’s core principles with precision yields stronger results than partial implementation of multiple curricula. As Dr. Akhter observed in her 2023 keynote at the Dhaka Early Childhood Summit, 'Samima does not teach children to fit the world. It teaches the world to recognize how children already make sense of it.'
The curriculum’s ongoing evolution—including planned integration of climate resilience concepts in 2025 (e.g., 'Monsoon Preparedness' play scenarios) and expanded sign-language support for Deaf learners—underscores its commitment to adaptive relevance. For researchers, Samima provides a replicable model for co-developing interventions where community voice shapes not just content but epistemology: what counts as knowledge, how it is transmitted, and who gets to define readiness.
For policymakers, it presents a compelling case for investing in teacher agency over scripted compliance—demonstrating that when educators are equipped with developmental science, cultural insight, and practical tools, they become architects of learning rather than conduits of curriculum. And for children, Samima affirms something fundamental: that their language, their environment, and their ways of knowing are not deficits to remediate—but foundations upon which all learning securely rests.
As enrollment in Samima-affiliated centers rose from 112,000 in 2020 to 327,000 in 2023—a 192% increase—the model’s scalability suggests that contextually intelligent design, when coupled with robust training infrastructure and clear fidelity benchmarks, can achieve both depth and reach. Future research priorities include longitudinal tracking into adolescence and cross-cultural validation of its socioemotional assessment tools beyond South Asian and East African contexts.
Ultimately, Samima’s contribution extends beyond outcomes data. It redefines quality early childhood education as a practice of recognition—of children’s existing competencies, of community knowledge systems, and of developmental science as a living, adaptable discipline rather than a fixed set of prescriptions. In doing so, it offers a blueprint not just for curriculum design, but for educational justice rooted in dignity, evidence, and place.
