We don't use buzzwords. Every feature in Kuliso is grounded in named, peer-reviewed research. This page shows you exactly what we read, and why it shaped what we built.
Most ed-tech companies claim to be "research-based." Few tell you which research. We do. Every feature listed on this page maps to specific studies, meta-analyses, or frameworks from independent researchers — not our own marketing materials.
Our design process starts with the question: what does the best available evidence say works for this population? We then build to that standard — and we're transparent when something is still emerging science versus settled consensus. If a finding can't be verified, we say "research suggests" rather than claim a specific number.
This page is written for principals, curriculum directors, and CAOs evaluating platforms for their schools. If you have questions about any citation or want access to the original papers, email us at support@kuliso.org.
Kuliso's reading instruction is built on the Orton-Gillingham approach — a systematic, explicit, multisensory method for teaching reading and spelling. Unlike whole-language or balanced-literacy approaches, OG-based instruction teaches the phonetic code directly and in a specific, cumulative sequence. The International Dyslexia Association (IDA) defines this as "structured literacy" and recommends it for all students, not just those with dyslexia. Research consistently shows it produces stronger outcomes than implicit or incidental reading instruction, especially for struggling readers and English language learners who need the explicit phonetic scaffolding.
Kuliso's math instruction follows the Concrete-Pictorial-Abstract progression — a sequence where students first manipulate physical or simulated objects, then work with visual diagrams and models, then move to abstract symbols and equations. This isn't just the Singapore math philosophy; it's rooted in Bruner's cognitive development research. Every Singapore Math problem in Kuliso moves students through this three-stage sequence rather than jumping straight to symbolic manipulation, which is where most traditional math instruction loses ELL students and struggling learners.
Students who read more, read better — but students who struggle tend to read less, falling further behind over time. This is the Matthew Effect: the rich get richer, the poor get poorer. Kuliso's reading stamina feature builds sustained reading volume through timed, low-stakes independent reading sessions at each student's instructional level. This directly addresses what researchers identify as one of the most powerful, under-used levers in reading achievement: simply increasing the amount students read each week.
Synthesis reading trains students to read multiple sources on the same topic and construct an argument or summary — the exact skill demanded by college entrance exams, AP assessments, and workplace writing. Kuliso builds this through structured reading-writing tasks with increasing text complexity. Research shows that writing about what students read dramatically improves both reading comprehension and retention, and that students benefit significantly from regular exposure to complex, grade-appropriate texts rather than simplified versions.
Phonemic awareness — the ability to hear, identify, and manipulate individual sounds (phonemes) in spoken words — is one of the strongest predictors of later reading success. Kuliso's phonemic awareness module systematically builds this skill through oral and auditory tasks before introducing written letters, following the developmental sequence identified by the National Reading Panel. For ELL students, this work in both the student's native language and English provides a stronger foundation for transfer.
Kuliso's SoBot character-based SEL module helps students build self-awareness, regulation, and interpersonal skills through guided reflection and scenario-based practice. The CASEL framework — the gold standard for school-based SEL — identifies these five competency areas as predictors of both academic and life outcomes. A landmark meta-analysis of 213 SEL programs found measurable academic gains of 11 percentile points alongside improved attitudes and behavior. Kuliso integrates growth mindset explicitly into every feedback cycle: mistakes are learning events, not failures.
Kuliso prompts regular screen breaks during sessions — not as a concession to screen-time concerns, but because the research on cognitive fatigue and attention restoration is clear. Students perform better after brief movement or rest breaks. The brain's directed-attention capacity depletes over continuous task engagement; restoration requires a different kind of engagement. Kuliso's breaks are short, prompted at appropriate intervals, and designed to support attention restoration rather than just limiting device time.
Kuliso's flashcard system doesn't just shuffle cards randomly. It schedules each card's review based on how well the student knew it last time, presenting difficult items more frequently and mastered items less often. This is spaced repetition — one of the most replicated findings in cognitive psychology. The spacing effect means that distributing practice over time produces dramatically better long-term retention than massed practice ("cramming"), with studies showing 200–300% improvement in long-term recall for spaced versus massed practice.
Kuliso tutors in students' native languages — not just as translation support, but as a principled pedagogical strategy. The research on translanguaging shows that allowing students to leverage their full linguistic repertoire during learning accelerates both content mastery and English proficiency. Cummins' BICS/CALP distinction explains why students who "seem conversational" in English still struggle academically: everyday English and academic English are different registers requiring different instruction. Kuliso addresses both simultaneously.
