A coherent conceptual approach to interdisciplinary and integrated STEM (I-STEM) is needed to guide classroom practices in terms of cross-disciplinary content learning and its underlying teaching, bonding to specific learning objectives
[6][7]. Due to the possibility of seamless integration of materials from different domains, I-STEM could strongly link to real-world experience in STEM fields. This integration has the potential to promote and improve the learning of each discipline involved
[8]. In order to effectively integrate different STEM disciplines, it is necessary to bring together ideas and principles from disparate disciplines
[9] PBL (problem-based and/or project-based learning)
[10] and interdisciplinary scientific inquiry
[6][11] are some of the pedagogical approaches that have been used to support I-STEM education. I-STEM success relies heavily on the PBL process, which is generally recognized as a key component of I-STEM
[12]. The real process of scientific inquiry cannot always be compartmentalized in such a tidy manner, and for achieving a solution, several disciplines necessarily need to link together. The goals of I-STEM include, but are not limited to, improving the students’ STEM literacy, 21st century skills, STEM job preparation, STEM interest and engagement, and the capacity to draw connections across STEM disciplines
[13]. Interdisciplinary and integrated approaches to teaching and learning, and teacher preparation that translates to classroom practices are key aspects to be focused on to produce a responsible generation that is capable of using the STEM knowledgebase for changes in practices
[14]. The interdisciplinary integrated approach of STEM education needs to ensure that democratic civic-informed decision making aligns with the Next Generation Science Standards
[2] and National Research Council
[5]. This approach could generate a knowledgebase for problem solving and could lead to democratic civic practices for attaining capacity for informed decisions. Effective use of interdisciplinary and integrated STEM involves different ways of thinking, solving problems, and communicating, and these approaches need consideration in building teachers’ capacity for innovation in classroom practices. Students not only used these approaches to learn a range of technological activities to plan, analyse, evaluate, and present their work, but also learn the valuable reasoning and thinking skills to find alternatives in socio-scientific issues and problems when they are used in classroom projects. These aspects are essential for functioning both within and outside the school environment and are about creativity, design principles, and processes involved. These are essentially required in interdisciplinary and integrated STEM knowledgebases. The nature of post-COVID-19 learning is innovative and interactive, enabled using the virtual online platforms where teachers and students take the initiative in generating active learning that emphasises the interaction rather than just the content. In this context, there is a possibility to incorporate societal issues that are connected to the daily life of the learner and involve multidisciplinary concepts to develop alternatives. These steps could better start from early ages and from primary schools to build interdisciplinary and integrated STEM education as an inquiry approach for problem solving.
Interdisciplinary and integrated approaches could use an authentic real-world context to unpack underlying disciplines with a proper inquiry approach. Enriching the science and mathematics learning context, the meaning of integrated STEM education extends in formal school settings and provides life practice. As an example, a popular technological engineering design can be used to contextualize mathematics and science teaching and learning and approach integrated and actionable knowledge. It may provide a practical solution for STEM teachers to address implementation issues of integrated content and pedagogy
[15]. The steps would start with an engaging and motivating context connected to engineering-based designs imparting mathematical and scientific content using student-centred practices, and students’ learning from mistakes. These steps using authentic settings will foster collaborations and lead to ownership of knowledge that is interdisciplinary and integrated.
