What Is STEM? Its Role in Education and How to Tell If a School Teaches STEM Properly STEM in modern education What is STEM? Why do so many schools mention STEM in their curriculum? And how can you tell whether a school is genuinely teaching STEM, rather than simply running a few hands-on activities and calling them STEM? These are questions many parents face when researching international schools, bilingual schools or modern educational programmes for their children. Understanding STEM properly helps parents assess a curriculum with a clearer eye. STEM is not just robots, coding or a state-of-the-art lab. At its core, STEM is about how students use knowledge of science, technology, engineering and mathematics to solve real-world problems. This article helps parents understand what STEM is, how STEM differs from STEAM, how STEM education is put into practice in schools, and the signs that a school is teaching STEM properly. What is STEM? STEM is an acronym for four fields: Science Technology Engineering Mathematics In education, STEM is not simply about teaching these four subjects separately. STEM education is a way of organising learning so that students combine knowledge from several fields to solve a specific problem. For example, rather than just learning the formula for area in a Maths lesson, students might take part in a project to design a small garden at school. They would need to measure the area, choose suitable plants, calculate how much soil is needed, estimate costs and explain why their design makes sense. An activity like this contains all the elements of STEM, because students do not just “know the formula” – they know how to apply it to a real situation. How does STEM education differ from studying science subjects separately? Many parents easily confuse STEM with doing well in Maths, Physics, Chemistry and Biology, or taking extra coding classes. In reality, STEM education is broader in scope. “What is STEAM?” is another common question when parents look into this approach. STEAM is an extension of STEM that adds the Arts to Science, Technology, Engineering and Mathematics. As a result, students not only solve problems through logical thinking but also develop creativity, an aesthetic sense and the ability to express their ideas. STEM education, meanwhile, places students in front of a problem that needs solving. To complete the task, students must draw on several areas of knowledge at once. A STEM lesson usually has three defining features: Interdisciplinary integration: Students use knowledge from several subjects. Learning through practice: Students observe, experiment, and build models or products. Solving real-world problems: The lesson is linked to a meaningful, real-life situation. A session spent building a model with no scientific knowledge behind it is just a hands-on activity. Likewise, studying the theory of technology without a real-world problem to solve is not STEM in the true sense either. Effective STEM education needs knowledge, a process of experimentation and reflection after the activity. How do STEM and STEAM differ? When reading admissions materials, parents may come across three terms: STEM, STEAM and STREAM. These terms share the same integrated thinking, but they differ in scope. Term Components When schools tend to use it STEM Science, Technology, Engineering, Mathematics When the focus is on scientific and engineering fields STEAM STEM + Arts When elements of creativity, design, fine art or performance are added STREAM STEAM + Reading or Robotics When emphasising academic reading or robotics STEAM is a popular variant at many international schools. Adding the arts helps students look at problems from a more creative angle. For instance, when designing a model bridge, students consider not only its load-bearing capacity but also its shape, colour and user experience. STREAM is less common. Some schools use STREAM to emphasise the skill of reading scientific texts in English. Others use the “R” to refer to Robotics. Parents should not judge by the name alone. What matters is whether the school genuinely designs integrated lessons. A programme labelled STEAM that simply adds an after-school painting session is not necessarily deeper than a well-structured STEM programme. The four core pillars of STEM Each letter in STEM represents an important pillar. Understanding each one helps parents assess the quality of a programme more clearly. Science: Observation and experimental thinking Science in STEM is not just about memorising definitions or formulas. Students need to learn how to ask questions, form hypotheses, observe phenomena, collect data and draw conclusions. For example, on the topic of air quality, students might observe differences between areas of the city. They could explore the factors that affect fine dust and discuss green spaces, traffic and daily habits. What matters is not whether students reach the “right” conclusion straight away. What is valuable is that they learn to base their thinking on evidence. Technology: Using tools to solve problems Technology in STEM is not limited to computers, robots or coding. Technology can be sensors, simulation software, spreadsheets, measuring devices, materials or processes that help people work more effectively. At primary level, technology can be very simple. Students use rulers, stopwatches or data tables to record the results of their experiments. At higher levels, students may use design, simulation, coding or data analysis software. The key point is that students understand what a tool is for, rather than using it simply because the activity looks “modern”. Engineering: Design thinking for solutions Engineering is what helps students move from “knowing” to “doing”. A lesson with an engineering element usually asks students to design, test, fail, fix errors and improve. For example, students are tasked with designing a paper tower that can bear a certain weight. They have to choose a shape, test materials, observe weak points and adjust their design. This process helps students understand that mistakes are not final failures. Mistakes are data for improving a solution. Mathematics: Modelling and decision-making Mathematics in STEM is not just about solving textbook exercises. Maths helps students measure, compare, calculate, predict and make decisions. For example, when designing a small planting area in the school grounds, students need to calculate the area, the spacing between plants, the amount of soil, the amount of water and the cost of materials. When maths is placed in a real-world context, students more easily understand why they need to learn measurement, ratios, charts or statistics. Exploring the four core pillars of STEM education How STEM lessons are designed in schools In Vietnam, a document often referenced in discussions of STEM education at secondary level is Official Letter No. 3089/BGDĐT-GDTrH dated 14 August 2020, issued by the Ministry of Education and Training (MOET). According to this guidance, a STEM lesson should be designed with clear objectives, a problem to solve and clear assessment criteria. The process of building a STEM lesson can be understood in four main steps. Selecting the teaching content Teachers start from the subject curriculum. The content chosen should match what students are currently learning and should not be detached from the core curriculum. For example, when studying forces, materials or structures, teachers might design a lesson around bridges, towers or load-bearing models. Identifying the problem to be solved A STEM lesson needs a problem that is clear enough to make students want to find a solution. The problem should not be too easy, or students will not need to apply their knowledge. Nor should it be too difficult, or students may lose motivation. For example: “How can we design a model bridge that is both lightweight and able to bear a given load?” This question requires students to think about materials, shape, forces and assessment criteria. Setting criteria for the product or solution Criteria help students know what their product needs to achieve. The clearer the criteria, the more focused the learning process. Criteria might include: Product dimensions Permitted materials Completion time Notional cost Durability or effectiveness Ability to present and explain With clear criteria, students understand that STEM is not just “making things for fun”. They need to explain why their solution makes sense. Designing the sequence of learning activities Teachers need to sequence activities so that students move from understanding the problem, to learning new knowledge, designing a solution, testing it and evaluating it. At this stage, the teacher’s role is not just to deliver a lesson. Teachers need to ask questions, observe student groups, suggest lines of thinking and offer support when students get stuck. A good STEM lesson usually includes time for students to reflect. They need to look back at what worked, what did not, and how they could improve next time. 3 ways schools organise STEM education Not every school organises STEM in the same way. Parents should distinguish between the three common approaches below. Teaching science subjects through STEM lessons This is STEM within core lessons. Teachers design STEM lessons based on the content of the current subject. For example, in Science, students learn about solar energy. The teacher might task them with designing a simple model that uses light to create movement or heat water. This approach matters because STEM is not separated off as an extracurricular activity. Students see that what they learn in class can be used to solve real problems. STEM experiential activities These include clubs, STEM days, science fairs, workshops and gallery walks. Students have the chance to display their products, give presentations and learn from their classmates’ work. STEM experiential activities are excellent for sparking interest. However, parents should see them as a complement. A school that holds a STEM day does not necessarily have an in-depth STEM programme in the classroom. Scientific and engineering research This approach suits students with greater ability or deeper interest. They may take part in research projects, science and engineering competitions or individual projects. At secondary level, this is an opportunity for students to build research skills, project management and academic presentation skills. Students presenting a model during a STEM activity STEM in the IB and other international frameworks In IB programmes, STEM does not necessarily appear as a standalone subject. The spirit of STEM is usually integrated through inquiry-based learning, interdisciplinary learning, research projects and designing solutions. At primary level, the IB PYP encourages students to learn through transdisciplinary themes. Themes such as “How the World Works” or “Sharing the Planet” can open up many activities related to science, the environment, technology and community responsibility. At lower secondary level, the IB MYP has the Design Cycle. Students move through the stages of inquiring, developing ideas, creating solutions and evaluating. This framework is very close to engineering thinking in STEM. Notably, the IB does not focus only on the final product. The programme encourages students to explain their thinking process, respond to feedback after testing and improve their solutions. For parents, the thing to look for is not whether a school uses the word STEM. What matters more is whether students get to ask questions, experiment, collaborate, analyse data and present solutions. How to tell if a school teaches STEM properly When visiting a school or reading its admissions website, parents can use the signs below to assess how well STEM is being implemented. STEM is integrated into lessons, not just events A school that teaches STEM properly does not just hold a STEM day once a year. STEM needs to be part of everyday learning, especially in science, maths, technology, design or interdisciplinary projects. Parents might ask: “Which subjects is STEM integrated into? How often do students do projects? Can you give an example of a specific lesson?” If the school responds only with event photos and no description of the learning process, parents should look into it further. Suitable spaces and tools Facilities are not the only factor, but they still matter. Students need dedicated learning spaces to observe, experiment, prototype, fix errors and present. Depending on the year level, the school provides international-standard creative, hands-on learning spaces such as a STEAM Lab or Maker Space, alongside dedicated project-based learning areas. However, expensive equipment does not in itself create good STEM education. If teachers do not know how to design lessons, robots or 3D printers are merely display pieces. Teachers know how to guide learning through questions STEM requires teachers who can ask questions and facilitate activities. Teachers should not just hand out model answers but help students observe, experiment and explain their choices for themselves. Parents might ask: “How are teachers trained in inquiry-based learning, project-based learning or STEM lesson design?” The more specific the answer, the more reliable it is. Student products and portfolios A school that genuinely implements STEM usually has student work on display or kept in portfolios. This might be models, design drawings, lab reports, science posters or presentation videos. Parents should look at whether the work reflects the learning process. A polished product with no explanation of the problem, criteria and improvements is not enough. Some schools hold an annual STEAM fair where students display their work and present to parents – a good opportunity to observe the real quality of what students produce. Assessing the process, not just marking the product STEM should not be assessed solely on the final product. Schools need to assess the whole process: how students ask questions, collaborate, experiment, record data, explain and improve. For example, two groups of students might create two different models. The group whose model is less than perfect can still learn a great deal if they can analyse why and suggest sensible improvements. This is the difference between learning for marks and learning to develop capability. Connections to real life A good STEM lesson should help students understand how knowledge relates to the world around them. Topics might come from the environment, energy, transport, health, agriculture, architecture or daily life at school. When students see that a problem is real, they are more motivated to find a solution. Opportunities to present and receive feedback STEM does not end when the product is finished. Students need to present their solutions, listen to questions and defend their choices. This helps students develop academic communication, critical thinking and the ability to learn from feedback. Hands-on spaces help students test their STEM ideas Checklist of questions to ask when visiting a STEM programme Parents can use the following questions when visiting a school: Dưới đây là bảng được chuyển đổi từ ảnh thành dạng văn bản Markdown để bạn dễ dàng sao chép: Question to ask What parents should look for Which subjects is STEM taught in? Whether STEM is part of the core curriculum How often do students do STEM projects? Whether it happens regularly or only as one-off events What process do teachers follow to design STEM lessons? Whether the school has a clear methodology How are students assessed? Whether process, portfolios and presentations are assessed Can you show examples of student work? Whether the work reflects thinking and experimentation What hands-on learning spaces does the school have? Whether facilities genuinely support learning Do students get to present their projects? Whether communication and critical thinking are developed This checklist helps parents avoid judging STEM solely by photos of a lab or robotics activities. Is STEM suitable for every student? STEM is not just for students who are strong at Maths or love robots. A student who loves nature may be drawn to an environmental project. A student who loves drawing can help design a model. A student who enjoys presenting may shine when explaining the solution. One of STEM’s strengths is that it creates many roles within the same project. Some students are good at analysing data, some are strong at design, some are careful when experimenting, and some present well. So rather than asking “Is my child suited to STEM?” in too narrow a sense, a better question is: “Will the school help my child engage with STEM in a way that suits their age, ability and interests?” Frequently asked questions about STEM At what age can children start learning STEM? Children can start developing STEM thinking from a very young age through simple activities – for example, watching a plant grow, sorting objects, stacking blocks, measuring water, counting things or testing which objects float. At a young age, STEM does not need to be complicated. What matters is that children are encouraged to observe, ask questions and experiment safely. Is STEM the same as robot coding? No. Robots are only a small part of technology and engineering. A project to grow vegetables, filter water, design a paper bridge or observe the weather can also be STEM if students apply interdisciplinary knowledge to solve a problem. Parents should not judge a STEM programme solely on whether the school has robots. Does STEM learning require a lot of investment in equipment? Not necessarily. Good equipment can support learning, but it cannot replace teaching methodology. Many STEM lessons can start with everyday materials such as paper, card, string, plastic bottles, rulers or data tables. What matters more is that teachers know how to design the problem, the criteria and the learning process. Can girls learn STEM? Absolutely. STEM does not belong to any one gender. Girls can thrive in science, technology, engineering, mathematics, design or research. What matters is that the learning environment encourages every student to take part, ask questions and try out a range of roles. How does STEM learning differ between state schools and international schools? State schools usually implement STEM in line with guidance from the Ministry of Education and Training, linked to the current subject curriculum. International schools usually integrate STEM within a broader curriculum framework, such as the IB, Cambridge or programmes based on inquiry-based learning. The difference lies not only in the name of the programme. Parents should look at how the school organises lessons, assesses projects, supports teachers and gives students opportunities to present their work. STEM or STEAM – which is right for my child? Neither is always better. STEM suits schools that want to focus on science, technology, engineering and maths. STEAM suits schools that bring the arts, design and creativity into the learning process. What needs checking is whether the programme is genuinely integrated. If the arts are added merely as a decorative activity, STEAM is not necessarily deeper than STEM. STEM is an educational approach that helps students connect science, technology, engineering and mathematics to solve real-world problems. When implemented effectively, STEM education not only helps students develop a deeper understanding of knowledge but also strengthens their critical thinking, experimentation, collaboration and presentation skills. Westlink is an IB World School authorised by the International Baccalaureate (IB) to offer the Primary Years Programme (PYP) since May 2024 and the Middle Years Programme (MYP) since December 2025. The school emphasises inquiry-based thinking and the practical application of knowledge through hands-on learning activities. In addition, STEM and STEAM projects provide opportunities for students to experiment with ideas, solve problems and develop collaboration skills. Located on a 2.5-hectare campus in Tay Ho Tay, Westlink offers dedicated learning spaces, including a Makerspace and science lab. The Westlink STEAM Fair 2026 also provided students with opportunities to showcase their practical projects, present their ideas and explain how they applied knowledge to real-world situations.
