Innovative Teaching Methods for STEM: Why Teachers Need More Support
Inquiry-based and project-based STEM approaches boost deeper learning and critical thinking, yet many teachers feel unprepared to use them. Here is what the research says and what needs to change.
The Curious Crew
There is broad consensus among researchers and policymakers that innovative pedagogies, including inquiry-based learning, project-based learning, and integrated STEM approaches, are among the most effective ways to develop deeper understanding, problem-solving skills, and critical thinking in young learners. These methods are particularly well suited to teaching complex subjects from an early stage of education, precisely when foundational attitudes toward science, mathematics, and technology are being formed.
Yet despite this consensus, a significant gap persists between what research recommends and what happens in most classrooms. While teachers generally feel confident in their subject knowledge and are open to trying new methods, many report feeling insufficiently prepared to implement innovative, student-engaging practices. The barriers are not about willingness. They are about curriculum constraints, lack of ready-made materials, and insufficient professional development.
If we want more children to develop the STEM skills Europe and the wider world urgently need, we must first address the support gap facing the educators who are expected to deliver that transformation.
What Are Innovative STEM Pedagogies?
Before examining the barriers, it is worth being precise about what we mean by innovative teaching methods in STEM:
- Inquiry-based learning (IBL): Students investigate questions, problems, or scenarios rather than passively receiving information. The teacher acts as a facilitator, guiding learners through a process of questioning, hypothesising, testing, and reflecting. IBL has been shown to significantly improve conceptual understanding and engagement in science and mathematics.
- Project-based learning (PBL): Students work on extended projects that require them to apply knowledge from multiple disciplines to solve real-world problems. PBL develops not only subject knowledge but also collaboration, communication, and self-directed learning skills.
- Integrated STEM approaches: Rather than teaching science, technology, engineering, and mathematics as separate subjects, integrated approaches connect them through shared themes, challenges, or contexts. This mirrors how STEM disciplines work in the real world and helps students see meaningful connections between subjects.
These approaches share a common philosophy: they place the learner at the centre, prioritise active engagement over passive reception, and treat curiosity and questioning as the starting point for learning rather than the endpoint.
What the Research Says: The TALIS Evidence
The most comprehensive evidence on how teachers experience and implement innovative practices comes from the OECD's Teaching and Learning International Survey (TALIS) 2018, the largest international survey of teachers and school leaders, covering 48 participating countries and economies.
The findings paint a paradoxical picture:
- Schools recognise the value of innovation. The vast majority of teachers and school leaders report that their schools are open to innovative practices and have the capacity to adopt them. On average across OECD countries, 78% of teachers say that they and their colleagues help each other implement new ideas.
- But cognitive activation is underused. Despite its high potential impact on student learning, only around half of teachers frequently use practices that involve student cognitive activation, that is, getting students to evaluate information, apply knowledge to new situations, and solve problems. The more traditional approaches of classroom management and clarity of instruction dominate, with at least two thirds of teachers relying primarily on these methods.
- Teachers want more training in innovative methods. While more than 90% of teachers had participated in at least one professional development activity in the year prior to the survey, many reported that the training they received did not adequately cover the implementation of innovative, student-centred pedagogies. Developing advanced ICT skills, teaching students with diverse needs, and implementing new assessment methods were among the areas where teachers most wanted further support.
- Collaborative learning works but is underutilised. Only 44% of teachers participate in professional development based on peer learning and networking, despite the fact that collaborative learning is identified by teachers themselves as one of the most impactful forms of training.
TALIS also found that teachers in Europe were less likely to report openness to innovation compared to teachers in other OECD regions, suggesting that systemic and cultural factors may be creating additional resistance in the very context where STEM skill shortages are most acute.
Why Teachers Feel Unprepared
The gap between teachers' willingness to innovate and their readiness to do so is not a failure of individual educators. It is a systemic problem with identifiable causes:
- Curriculum constraints. In many education systems, curricula are prescriptive and content-heavy, leaving little room for the open-ended exploration that inquiry-based and project-based learning require. Teachers who want to spend a week on a genuine investigation may find themselves pressured to "cover" a list of topics instead. When the curriculum is designed around content delivery rather than competence development, innovative pedagogies are treated as luxuries rather than necessities.
- Lack of ready-made materials. Implementing inquiry-based or project-based STEM lessons requires significant preparation: designing investigations, sourcing materials, anticipating student questions, and creating assessment rubrics that capture process as well as product. Many teachers, particularly in primary education, do not have access to high-quality, age-appropriate materials that make this transition manageable within their existing workload.
- Insufficient initial training. The TALIS 2018 data shows that during their education and training, teachers were instructed primarily on subject content, pedagogy, and classroom management. More specialised areas, such as using ICT effectively for teaching (covered in the training of only 56% of teachers) and teaching in diverse settings (35%), were far less commonly included. If innovative STEM pedagogies are not modelled and practised during initial teacher education, expecting teachers to adopt them independently in the classroom is unrealistic.
- Limited time for professional development. Around half of teachers and principals report that their participation in available professional development is restricted by scheduling conflicts and lack of incentives. Even when effective training programmes exist, the structural conditions of teachers' working lives often prevent them from accessing those opportunities.
- Assessment systems that reward recall over reasoning. When student success is measured primarily through standardised tests that emphasise factual recall, teachers face a powerful disincentive to spend time on inquiry-based approaches that develop deeper understanding but may not directly prepare students for traditional examinations.
Why This Matters for Children
The consequences of this support gap fall most heavily on the learners. When innovative teaching methods remain the exception rather than the norm, children miss out on the kinds of learning experiences that research consistently shows to be most effective for building STEM competence and confidence.
The National Academies of Sciences, Engineering, and Medicine (2022) concluded that children in preschool and elementary school are capable of learning sophisticated science and engineering concepts, and that the most effective approaches are those where children's ideas, interests, and practices are treated as meaningful. In other words, exactly the kinds of inquiry-based, student-centred approaches that teachers report feeling unprepared to deliver.
When teaching defaults to lecture-style content delivery and worksheet-based practice, the children who disengage first are often those who would have thrived in a more exploratory environment: creative thinkers, hands-on learners, and children whose curiosity does not fit neatly into predetermined answers.
The European Commission's Education and Training Monitor 2024 highlights that Europe's STEM enrolment at both VET and higher-education levels remains significantly below 2030 targets. For a deeper analysis, see our article on Europe's growing STEM skills gap. If we want more young people to choose STEM pathways, we need to ensure that their early experiences of science and mathematics are engaging, meaningful, and inquiry-driven, and that requires equipping teachers with the tools and training to make it happen.
What Needs to Change
Closing the gap between innovative STEM pedagogy and classroom reality requires coordinated action across multiple levels:
For Policymakers and Education Systems
- Reform curricula to create space for inquiry. Curricula that are structured around key competences and essential questions, rather than exhaustive topic lists, give teachers the flexibility to implement inquiry-based and project-based approaches without feeling they are falling behind.
- Embed innovative pedagogies in initial teacher education. Future teachers should not just learn about inquiry-based and project-based methods. They should experience them first-hand during their training, building confidence through practice before they enter the classroom.
- Invest in high-quality, accessible materials. Developing and freely distributing curriculum-aligned resources for inquiry-based STEM teaching removes one of the biggest practical barriers teachers face. These should include lesson plans, investigation guides, assessment frameworks, and adaptations for diverse learners.
- Create time and incentives for collaborative professional development. The TALIS evidence is clear: teachers learn most effectively through collaborative, practice-based professional development. Education systems need to build protected time for this into the school calendar, not treat it as an optional extra.
For Schools and School Leaders
- Foster a culture of experimentation. School leaders play a critical role in creating environments where teachers feel safe to try new approaches, learn from what does not work, and share their experiences with colleagues.
- Support cross-disciplinary planning. Integrated STEM approaches require teachers to collaborate across subject boundaries. Scheduling common planning time and encouraging joint projects can help break down the silos that prevent integration.
- Rethink assessment practices. When schools use assessment to capture problem-solving, inquiry skills, and collaborative work alongside content knowledge, they send a clear signal that innovative teaching is valued, not just tolerated.
For Parents and Caregivers
- Ask open-ended questions at home. "What do you think would happen if...?" and "How could we find out?" are the same kinds of questions that inquiry-based teaching uses. When children practise this kind of thinking at home, it reinforces and extends what they experience in school.
- Celebrate the process, not just the answer. When a child explains how they figured something out, even if the final answer is wrong, they are doing exactly the kind of reasoning that innovative STEM education aims to develop.
- Provide hands-on experiences. Building, experimenting, cooking, gardening, and exploring nature are all forms of inquiry-based learning. They complement and support what happens in the classroom. See our guide to STEM sets and why hands-on education matters.
How The Curious Crew Supports Innovative Teaching
At The Curious Crew, we design resources that help bridge the gap between innovative pedagogy and everyday practice. Our books and conversation starters are built around the principles of inquiry-based learning: they pose questions rather than deliver answers, they invite children to hypothesise and explore, and they create natural starting points for the kinds of investigations that research shows are most effective.
For educators who want to bring more inquiry into their practice but are unsure where to start, our resources offer a low-barrier entry point. A story can become a science investigation. A conversation prompt can become a classroom debate. A character's question can become a week-long project.
We also work with schools and organisations to develop bespoke programmes that integrate storytelling with hands-on STEM learning, providing the ready-made, curriculum-aligned materials that teachers tell us they need most.
Because the evidence is clear: when teachers are equipped with the right tools, training, and support, they do not just adopt innovative methods. They transform learning. And that transformation is exactly what the next generation of curious minds deserves.
