Integrated STEM education refers to T&L of scientific, technological, engineering, and mathematical knowledge and skills in integrative ways, emphasizing the connection between abstract knowledge and real-world problems. Integrated STEM education is characterized by four core features: multidisciplinary integration, real-world application, authentic inquiry or design-based practice, and active student learning. Based on 124 extracted and coded studies (2010-2022), Chen et al.’s (2025) meta-analysis reports on the effects of integrated STEM education based on three main types of interventions: (1) adopting integrated STEM education, (2) using extra teaching and learning strategies to enhance integrated STEM education, and (3) using specific learning technologies to support integrated STEM education.
All three types of interventions yielded a medium effect on knowledge acquisition and a small effect on student perceptions. Besides, adopting integrated STEM education had a large effect on cognitive skills; using extra teaching and learning strategies in integrated STEM programs produced a medium effect on cognitive skills and problem-solving task performance; using specific learning technologies had a small effect on problem-solving task performance. Some factors, such as task type (inquiry or design-based task) and program duration, may influence STEM learning outcomes.
To maximize the efficacy of integrated STEM education, practitioners should embed its four core characteristics into curriculum design while favoring short-to-medium duration programs (one month to a semester). Educators must carefully balance hands-on design and minds-on inquiry tasks by providing necessary scaffolding tailored to students’ prior knowledge. Furthermore, deploying targeted instructional strategies and learning technologies can enhance engagement with complex, real-world problems. Ultimately, evaluating these programs requires a multidimensional approach that prioritizes skill development and practical problem-solving performance alongside traditional knowledge acquisition.
