Engineering design practices in STEM education focus on reflecting the discipline-specific work of engineers in a manner that is suitable for the student level and course learning objectives. Using an engineering design context also facilitates student identification of global problems and feasible solutions to address such problems. In this article, within the framework of STEM approach, an engineering design activity that can be applied in middle school mathematics course is presented. Additionally, examples of students’ experiences of the engineering design-based mathematics activity are given. The "Cold Storage Design Activity" was executed in a classroom setting, and the implementation process underwent examination and evaluation. 12 eighth-grade students from a middle school in Turkey took part in the implementation. The middle school were able to successfully perform an engineering design process and effectively overcome challenges through teamwork. The results of the activity show that middle school students are excited and eager to participate in a design activity.

Below the surface of the ocean, currents, eddies, and other physical processes redistribute energy and biologically important elements. Measuring this transport can be challenging, and scientists must address a wide spectrum of oceanographic and engineering concepts when designing instruments to observe these processes. In this activity, high-school aged students are asked to consider some of these challenges by using easily-available material to design, assemble, and test their own simple deep-water floats, mimicking a tool used by oceanographers to measure transport below the ocean’s surface. Students are asked to build floats that are neutrally buoyant at an interface between oil and water, teaching them key oceanographic concepts such as buoyancy and ocean stratification. Additionally, students manage a budget by selecting cost-effective materials to construct their floats. This activity aims to increase students’ understanding of how ocean currents affect our planet’s climate and ecosystems, how we observe these phenomena, and some of the practical challenges that oceanographers face. The project supports key educational standards and aims to deepen students’ appreciation for marine science.

This STEM research project asks middle school or high school students to work towards creating ecologically friendly packaging. Packaging that can be composted instead of thrown away and collected in landfills and oceans like plastics. This inquiry uses nanocellulose and focuses on water permeability. The fibers of nanocellulose can be dried to make a rather strong and thin film, but due to the spaces between the fibers the film is too water permeable and therefore makes poor packaging materials on its own. Students will create nanocellulose composite films with other biodegradable materials, in an attempt to fill the inter-fiber microscopic spaces and create a new film that can be easily tested for water permeability. Students set up a straightforward science experiment with films, water, and mason jars. They will collect and graph data to determine if their nanocellulose composite films reduce water permeability compared to plain nanocellulose and how close they are to the present standard, plastic. This research is an amalgam of disciplinary core ideas like properties and states of matter, as well as a combination of science and engineering practices. It ignites students’ curiosity, provides an organic path to science fair extensions, while also helping to cultivate future scientists, engineers, and environmental activists.

Argumentation plays a central role in the development and justification of scientific knowledge. Learners could attain a more scientifically acceptable conceptual understanding by attending argumentation-based discussions. During argumentation-based discussions, students need to activate some metacognitive processes related to concept learning, such as being aware of their and others’ existing concepts, monitoring the consistency between their own claims and counterclaims, and evaluating the validity of the evidence they applied to justify their claims. In this article, some prompts were inserted that aim to activate preservice science teachers’ (PSTs’) metaconceptual processes explicitly and systematically into the stages of Predict-Observe-Explain activities, one of the ways to engage students in argumentation. This activity aimed to facilitate PSTs in constructing more scientifically acceptable concepts about simple electrical circuits by ensuring the activation of various metaconceptual processes as they justify or reason the validity of different claims.

Physically active learning is considered to enhance learning and additionally addresses health goals like increasing activity levels and reducing obesity. However, physically active learning has rarely been applied to science and engineering learning, or utilized with younger learners (e.g under sevens). This article describes a physically active learning approach to introducing one area of science and engineering, trialed with children from age 3 upwards. Specifically, the game bacteria-tag was designed to start discussions around bacteria and diseases and medicine selection, which can be extended in various ways, e.g. to introduce ideas around antimicrobial resistance, bacteria structure etc. Additionally, the game helps to highlight the role of bioengineers in society, helping to broaden perceptions around engineering, which is especially useful at a young age where misconceptions can lead to lack of interest and career rejection. Bacteria-tag has been successfully utilized in a range of schools and nurseries (PreK to 5th grade), proving effective at engaging children and inspiring learning.

The use of digital technologies as teaching and learning materials supports and enhances science learning, encouraging students to develop valuable inquiry skills and knowledge. In response, this paper seeks to explore digital inquiry-based learning as a useful aid for teaching the elementary school science curriculum on plants in Malaysia. There is a strong rationale for this work, as (i) this curriculum has received less attention compared to the equivalent on animals, and (ii) students have developed misconceptions about plants, typically in the areas of plant nutrition and photosynthesis. Thus, the paper describes a 5E Instructional Model lesson plan, which uses various digital technologies to tackle different inquiry elements at each instructional model stage. The goals of the activities are to help students: (i) assess their preexisting knowledge and engage with a new concept, (ii) create predictions and document their observations, (iii) display their conceptual understanding, (iv) gain a more profound and broader understanding through new experiences, and (v) examine their understanding and abilities with the aid of digital technology resources. The suggested activities are further discussed in relation to different types of digital technologies and evidence-based practice, thus encouraging other educators to integrate digital inquiry-based learning into their work.

This study presents a rollercoaster activity including virtual reality and following the six-steps engineering design process. In the study, a real-life problem involving a rollercoaster accident was given to 12 pre-service science teachers first. The participants were then asked to imagine, plan, create, and test a rollercoaster without an impulsion or braking system that could prevent this kind of accident. The pre-service teachers worked in groups to design their rollercoaster in three 50-minute sessions. After designing their rollercoasters, the pre-service teachers were shown a rollercoaster video with VR glasses so that they could test their designs by noticing the faulty parts. After they improved their designs, each rollercoaster was evaluated by the researchers using the rubric. The activity is critical in providing pre-service science teachers with an example of integrating the STEM approach into their lessons and incorporating virtual reality in STEM education. The activity also can help students become entrepreneurial thinkers and understand how science is connected to other disciplines such as technology, mathematics, or engineering. The activity can also help students develop 21st-century skills such as collaboration, critical thinking, creativity, problem-solving, and analytical thinking.

Within the scope of the current study, the researchers developed activities for middle school students to raise their awareness on the harm of plastics and microplastics, which are detrimental to nature and living things. In addition, through the activities developed, the study aimed to provide students with knowledge of and experience with bioplastics, which have emerged as an alternative to plastic materials and are environmentally friendly. Twelve eighth grade students participated in the current study. The activities developed by the researchers within the framework of the REACT strategy covered a four-week period. The researchers made sure that the activities designed included each step of the REACT strategy (Relating, Experiencing, Applying, Cooperating, Transferring) and the researchers used different tools (mind map, concept map, Vee diagram). The study suggests that activities designed for classroom use should be integrated with tools such as Vee diagram, concept map and mind map in order to increase students’ knowledge and awareness about global environmental problems as well as support students’ ability to produce solutions to such problems.

Gamified-integrated STEM is a technique that combines integrated STEM stages with gamification elements and can engage individuals in climate change communication. This paper presents a gamified-integrated STEM activity focused on global climate change. The activity includes gamified-integrated STEM instructional stages implemented in 6 lesson hours. The game elements used in the activity were time, rewards, points, badges, leaderboards, materials, stories, goals, and rules. Badges included: Decoders, Explorer, Meteorologist, Climatologist, Benevolent Koala, Scientist, and Engineer. The activity was designed for middle school students and aligned with the Next Generation Science Standards. Educators are encouraged to incorporate this pedagogical activity within their instructions to elucidate fundamental concepts related to the consequences of climate change. In doing so, teachers can promote student engagement, improve awareness, and refine problem-solving competencies pertinent to climate-centric challenges. The activity has been evaluated and recommendations for enhancement have been made to ensure optimal efficacy in cultivating gamification and a nuanced understanding of climate-related topics among learners.

Integrating scientific disciplines through a transdisciplinary approach is a pivotal component of contemporary learning paradigms, fostering educational experiences that transcend monodisciplinary boundaries and embrace the integration of diverse fields. Addressing this imperative, we collaborated with educators in Indonesia to devise a learning framework that interweaves mathematics, biology, and cultural dimensions by utilizing the context of Tempeh production – a traditional fermented food in Indonesia. This article delineates the intricacies of our pedagogical design, encompassing eight key stages: briefing, contextualization, exploration, action 1 to action 4, and reflection. Furthermore, we present a comprehensive analysis of students’ reflective writing, employing thematic analysis across six stages, namely description, feelings, evaluation, analysis, conclusion, and action plan. This initiative seeks to forge connections between scientific disciplines and to furnish students with theoretical knowledge and tangible and pragmatic experiences.
