Gender, confidence, intelligence, and the early architecture of belonging in STEM
The decision starts long before the subject choice
A girl does not usually wake up one morning and decides that science is not for her. More often, that decision is assembled gradually, through a thousand small signals that adults may barely notice. It is shaped by the toys placed in her hands, the stories placed on her shelf, the questions adults encourage or interrupt, the kind of mistakes she is allowed to make, the subjects that are described as “hard,” and the invisible comparison between the child who answers quickly and the child whose thinking arrives quietly, slowly, or through her hands.
By the time a girl is old enough to choose a school subject, join a robotics club, avoid a coding class, or say “I’m just not a maths person,” she may already have absorbed years of instruction about what kind of mind the world expects her to have. Much of that instruction is never written into a curriculum. It comes through color-coding, praise, jokes, gift choices, classroom habits, cartoons, family assumptions, and the subtle distinction between what adults call “cute” in girls and “clever” in boys. When we talk about girls and STEM only at the level of university enrollment or career pipelines, we arrive very late to a story that began in early childhood.
The STEM gap is not an ability gap
This is why the underrepresentation of women in STEM should never be mistaken for an ability gap. Globally, women now participate in higher education at high rates, yet UNESCO reports that women account for only about 35% of science graduates and remain a persistently low share of researchers. In the European Union, Eurostat reported that women represented 41% of scientists and engineers in 2023. These numbers show progress, but they also show how stubbornly the gap persists, especially in fields associated with engineering, computing, technology, private-sector research, and technical innovation.
The temptation is to interpret these statistics as if they reflect individual preference alone. Perhaps girls simply choose other fields. Perhaps they are less interested. Perhaps, some still imply, the technical world is naturally more appealing to boys. But that explanation ignores how preferences are formed. Children do not choose in a vacuum. They choose from the futures that have been made visible, desirable, safe, and believable to them. A girl cannot easily imagine herself in a room she has never been invited to enter, and she is less likely to persist in a field if she has been taught, long before formal selection begins, that brilliance, machines, risk, invention, and technical authority belong somewhere else.
The evidence that these patterns begin early is difficult to ignore. OECD analysis found that, across OECD countries, only 5% of girls expected to pursue careers in engineering and computing, compared with 18% of boys. That difference is not a small divergence in teenage taste; it is a sign of a cultural sorting process already well underway. Even more strikingly, research published in Science found that gendered ideas about “brilliance” can emerge around age six, with girls becoming less likely than boys to associate brilliance with their own gender and less interested in activities described as being for children who are “really, really smart.” A Princeton summary of the study highlights the same concern: the stereotype does not wait until adolescence to begin shaping children’s choices.
The quiet curriculum of toys, praise, and expectation
What makes this so troubling is that the messages are often ordinary, affectionate, and socially accepted. No one has to tell a girl directly that engineering is not for her if the material world around her has already done the speaking. If she receives dolls, pretend kitchens, beauty kits, and homemaking sets while boys receive construction toys, coding games, vehicles, science kits, and tools, the lesson is delivered quietly but repeatedly. This does not mean dolls are bad, or that care, domestic imagination, and nurture are less valuable than building. The problem is not that girls are offered care. The problem is when they are offered care instead of construction, beauty instead of experimentation, decoration instead of design, and compliance instead of risk.
Toy culture matters because play is one of the first laboratories of identity. Through play, children practice what it feels like to manipulate the world, solve problems, take things apart, negotiate rules, build systems, repair mistakes, invent scenarios, and imagine adult roles. NAEYC’s research summary on gender-typed toys notes that toys associated with girls are often linked to physical attractiveness, nurturing, and domestic skill, while toys associated with boys are more often linked to construction, competition, excitement, danger, and spatial development. The researchers cited by NAEYC also observed that neutral or moderately gender-typed toys tended to support broader skill development than strongly gender-typed toys.
This is not a trivial consumer issue. It is a cultural curriculum. A child who is repeatedly invited to arrange, soothe, decorate, and care may develop valuable capacities, but if she is not also invited to build, test, code, measure, climb, design, and fail safely, she receives a narrower map of her possible self. A boy who is denied care loses something too. Gender stereotypes impoverish everyone, but they do particular damage when they steer girls away from the technical, spatial, experimental, and problem-solving experiences that later make STEM feel familiar rather than foreign.
Intersectional barriers make the path narrower for many girls
The barriers are also not distributed equally among girls. Gender never acts alone. Poverty, disability, race, ethnicity, language, migration status, geography, school quality, family expectations, digital access, trauma, and the availability of role models all shape whether STEM feels reachable. A girl in a well-funded school with a robotics club, reliable internet, books at home, safe transport, and adults who recognize her curiosity is not navigating the same landscape as a girl in an under-resourced community with limited enrichment opportunities and fewer visible examples of women in scientific or technical roles. The phrase “girls in STEM” can sound universal, but the barriers are deeply intersectional.
This is why serious work on STEM participation must go beyond slogans of encouragement. UNICEF’s report on girls’ education through STEM frames STEM education as a way to transform gender norms and expand learning opportunities, but it also makes clear that access, equity, and social context matter. A girl may be curious and capable, yet still lack materials, mentors, emotional safety, time, school support, or digital access. When adults say “girls can do anything,” we must also ask whether girls have been given the resources, environments, and repeated experiences of belonging that make that sentence feel true.
The other barrier: a narrow definition of intelligence
There is another barrier that receives less public attention but is just as formative: the narrow way many educational settings define intelligence. Even when girls are encouraged to succeed, the model of “smart” they encounter can be painfully limited. Smart is often treated as fast, verbal, confident, tidy, correct, measurable, and visible on command. The child who raises her hand quickly is recognized. The child who finishes first is praised. The child who gives the answer the adult expected is marked as capable. The child whose intelligence is observant, careful, experimental, relational, spatial, musical, ecological, or quietly analytical may not receive the same recognition.
This matters because children build academic identity through comparison. A child who believes that smartness looks like someone else may begin to withdraw from the very experiences that would help her grow. She may avoid difficult problems because difficulty feels like exposure. She may interpret mistakes as proof that she does not belong. She may choose the safer activity, the familiar subject, the path where she already feels approved. She may not understand that the child who knows the answer quickly and the child who asks a better question slowly are both doing important intellectual work.
Education often claims to value curiosity, but classroom systems can reward compliance more consistently than inquiry. We tell children to ask questions, but we organize learning around correct answers. We tell them mistakes are part of learning, but we grade them in ways that make mistakes feel permanent. We tell them creativity matters, but we often reserve the highest academic status for speed, precision, and performance under pressure. For many children, especially those who are already navigating gender stereotypes, this creates a double filter: first, they must believe STEM is for girls; then, they must believe their own way of thinking counts as intelligent enough to enter it.
Confidence is not a soft extra
The emotional dimension is not secondary. Confidence and academic development are not separate worlds. A large meta-analysis of 213 school-based social and emotional learning programs, involving more than 270,000 students, found improvements in social and emotional skills, attitudes, behavior, and academic performance, including an 11-percentile-point gain in achievement compared with controls. CASEL’s summary of the evidence makes the broader point clearly: children’s emotional skills, relationships, sense of self, and school climate are connected to learning outcomes.
This should not surprise us. Children do not learn as disembodied brains. They learn through attention, safety, memory, relationships, belonging, motivation, and self-concept. A child who feels stupid is not simply having an unpleasant feeling; she may be receiving a message that shapes what she attempts, how long she persists, and what future she imagines. A child who feels emotionally safe enough to try, fail, revise, and ask again is not being indulged. She is being given the conditions under which learning can become durable.
This is especially important for children living with adversity. The CDC explains that adverse childhood experiences can affect health, well-being, attention, decision-making, learning, and long-term opportunities. Children facing instability, stress, poverty, violence, exclusion, or other forms of difficulty do not need adults to lower expectations. They need adults to strengthen the scaffolding around learning: emotional safety, accessible tools, encouraging language, flexible entry points, and opportunities to experience themselves as capable. For these children, confidence-building is not a decorative extra. It is part of educational justice.
Many kinds of smart, without turning children into labels
The language of “many kinds of smart” is one way to open this conversation with children, but it must be used responsibly. Howard Gardner’s theory of multiple intelligences helped challenge the idea that intelligence is a single, general capacity measured in one narrow way, but Gardner himself has warned against confusing multiple intelligences with simplistic “learning styles.” Harvard Graduate School of Education has published Gardner’s clarification, and that caution matters. Children should not be sorted into fixed categories, as if one is permanently “visual,” another “logical,” another “creative,” and another “not academic.” Labels can become cages when used carelessly.
The deeper educational value lies elsewhere. The point is not to diagnose a child’s intelligence type, but to pluralize the ways children recognize thinking, contribution, and capability. A child can be helped to see that observation is intellectual work, that carefulness is intellectual work, that pattern recognition is intellectual work, that building is intellectual work, that care can be intellectual work, and that asking questions is not the opposite of knowing but the beginning of inquiry. This broader language matters because children need more than encouragement. They need concepts that help them interpret themselves generously and accurately.
When we say a child is “quiet-smart,” we are not saying she should remain quiet forever or that quietness is her destiny. We are saying that listening, noticing, and watching closely can be powerful forms of intelligence. When we say a child is “messy-smart,” we are not romanticizing chaos. We are saying that experimentation, material exploration, prototypes, wobbly attempts, and revision are part of how ideas become real. When we say a child is “helping-smart,” we are not pushing girls back into gendered caregiving roles. We are reclaiming care as design intelligence: the ability to notice barriers, imagine access, and ask what would make a system safer, easier, kinder, or more welcoming.
STEM has more doors than children are usually shown
This is where early STEM confidence can become more humane and more inclusive. STEM is too often presented to children as a world of correct answers, difficult machines, exceptional geniuses, and competitive achievement. But science also begins with noticing. Engineering begins with trying to solve a problem. Mathematics begins with patterns. Technology begins with tools designed for human purposes. Environmental science begins with attention to the living world. Invention begins with the question, “What if this could work differently?” If we introduce STEM through these wider doors, more children can recognize themselves before they are asked to specialize.
This wider definition matters not because it makes STEM easier in a superficial way, but because it makes the entrance more honest. Real STEM work does require knowledge, discipline, practice, frustration, revision, and rigor. But rigor is not the opposite of imagination, and technical skill is not the opposite of care. The child who notices carefully, asks deeply, builds imperfectly, sees patterns, or thinks about how tools affect people is already practicing habits that belong in scientific and technical life. The task of education is not to flatten those habits into one acceptable version of achievement, but to help children develop them into stronger forms.
Why REDefine created the Girls in STEM Discovery Library
This is the context in which REDefine created the Girls in STEM Discovery Library. The series did not begin with a desire to produce another generic “girls can do science” product. It began with a more specific concern: many girls need to encounter STEM before it becomes intimidating, and they need to encounter it through a definition of intelligence wide enough to include the way their own minds actually work. The flagship picture book, The Kind of Smart I Am, was designed as an identity anchor rather than an instruction manual. It begins with a child who compares herself to girls who answer quickly, raise their hands, count big numbers, build tall towers, and seem to know just what to say. Instead of rushing past her uncertainty, the book stays with it and asks what many children quietly ask: am I smart if I am quiet, if I make mistakes, if my ideas come slowly?
The answer the book offers is not inflated praise. It does not tell the child she is the best at everything, nor does it pretend that confidence alone removes structural barriers. Instead, it gives children a vocabulary for recognizing intellectual dignity in different forms. Quiet-smart notices. Question-smart wonders. Messy-smart experiments. Careful-smart takes time and checks again. Pattern-smart sees what repeats. Building-smart turns ideas into structures. Nature-smart listens to the living world. Helping-smart uses ideas to make things safer, easier, and more welcoming. These are child-friendly phrases, but they carry a serious pedagogical intention: to make visible the kinds of thinking that often sit at the roots of scientific, mathematical, engineering, ecological, and design work.
From identity to practice: the companion books
The companion coloring books extend that identity work into practice. Curious Girls Can Do Science is designed as an early STEM coloring companion for younger children, with simple invitations into plants, weather, space, movement, animals, tools, building, and invention. It uses coloring and gentle prompts to make science feel friendly and possible rather than formal and intimidating. Brilliant Girls in STEM is a broader color-and-learn companion for children ready to explore astronomy, Earth science, biology, engineering, simple machines, design thinking, coding, logic, patterns, and women and girls in STEM. Together, the books move from identity to exploration: first, a child is invited to recognize that her mind matters; then, she is offered hands-on ways to observe, color, ask, test, imagine, and build.
The design choices are intentionally modest. These books do not claim to solve the gender gap in STEM. They do not replace high-quality teaching, equitable school funding, mentorship, public policy, digital access, inclusive classrooms, or structural reform. They are small tools within a much larger ecosystem. Their purpose is to give parents, teachers, caregivers, librarians, and community educators a way to begin earlier and more gently. A picture book can open a conversation that a worksheet cannot. A coloring page can lower the emotional stakes of a new topic. A repeated sentence can become a child’s private counter-message when comparison begins to narrow her confidence.
Coloring, in this context, is not filler. It slows attention. It gives children time to look. It makes learning tactile, creative, and non-threatening. It creates space for adult-child conversation without requiring the child to perform knowledge immediately. A page about plants can become a question about roots, water, and time. A page about weather can become an observation at the window. A page about bridges can become a conversation about strength, balance, and revision. A page about invention can become permission to imagine a problem differently. This is early STEM not as pressure, but as invitation.
A mission beyond the bookshelf
The series also reflects a broader commitment within REDefine’s work: education should help children imagine better futures, but it must do so with attention to inclusion, access, and emotional reality. It is not enough to tell children to dream if only some children receive the tools, safety, and encouragement to practice dreaming. It is not enough to celebrate future scientists while ignoring the children who cannot afford enrichment materials, who do not see themselves represented, who are navigating adversity, or who have already decided that “smart” belongs to someone else.
For that reason, revenue from the Girls in STEM Discovery Library supports REDefine’s mission to create inclusive educational materials and provide assistance to children in difficulty, including children affected by adverse childhood experiences and children who cannot otherwise access STEM learning and confidence-building resources. In practical terms, book revenue helps us continue creating and distributing child-friendly STEM confidence materials, support educational activities, and make resources available to children and communities that may not easily access them otherwise. This is not a decorative note at the end of a product description. It is part of the reason the series exists. If early confidence, representation, and access matter, then the benefits of this work should reach beyond the children whose families can easily buy another book.
Before the door closes
Before a girl decides she is not a science kid, she deserves to meet science as noticing, wondering, caring, building, testing, pattern-seeing, and trying again. Before she decides she is not good at maths, she deserves to see patterns in shells, music, beads, spirals, stars, bridges, and code. Before she decides mistakes mean she should leave the room, she deserves to experience mistakes as part of making. Before she accepts a narrow definition of intelligence, she deserves a wider and more honest one.
There are many ways to be smart. That sentence is simple enough for a child, but serious enough for education systems to take seriously. One of the most important things adults can do is make sure children hear it early enough, often enough, and in enough forms that they believe it before the world teaches them otherwise.
