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…

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,…

We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

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,…

Students have several misconceptions about thermodynamics. However, an understanding of basic concepts in this branch of physics remains fundamental to explain thermal phenomena. The purpose of this activity was to extend students' conceptual understanding of heat, temperature, energy, and thermal insulators and conductors. Two groups of students…

This activity provides opportunities for middle school students to design bio-inspired, eco-friendly vehicles. Twenty-four 8th grade students (12 girls, 12 boys) engaged in the activity which was implemented in four class periods, 40 minutes each, in an elective Environmental Education course. During the activity, students engaged in engineering…

The goal of this study is to present and evaluate a different way of teaching concepts related to the reflection of light (incident beam, reflecting beam, angle of incidence, angle of reflection, surface, regular reflection, and diffuse reflection). The participants were 42 sixth-grade students (between the ages of 11 and 12) attending a public…

The purpose of this study is to design an argumentation activity for third-grade students learning about the features defining matter. The research was carried out with seven students who enrolled in a tutoring program in a science and art center in the Eastern Black Sea region of Turkey during the academic year of 2017-2018. The activities were…

The purpose of the current study is to design and develop an Arduino-assisted robotic and coding activity in compliance with the 5E learning model for middle school students to construct knowledge and realize learning in science teaching. The study was conducted on 6th grade students attending a private middle school in Turkey in the second term…

The ecological footprint concept is important in order to evaluate the human impact on the environment and propose sustainable solutions in our life. By calculating ecological footprint, people could analyze the impact of their lifestyle on the natural environment. The purpose of this study is to share an ecological footprint education module for…
