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…

The present study aimed to develop, introduce, and conduct an activity for the integration of augmented reality to the jigsaw IV technique in a planned and systematic manner. The activity developed for secondary school students is related to the "Pure Substances" subject which it is included in the "Particulate structure of…

Problem-based learning (PBL) instruction tasks students with solving a real-world, relevant problem and provides a motivating context for learning science content. It also affords a natural opportunity for students to intentionally engage in a variety of engineering practices and components of engineering design if the problem scenario…

Abstract concepts, such as gravity, may provide the perfect opportunity to bring phenomena into the classroom. As a knowledge generation strategy, summarizing can foster that opportunity. Using phenomena and summary writing together might help student learning since it requires making connections between their ideas and words to explain the…

Assistive technologies are frequently used to help disabled students to access core and expanded core curricula and to improve their functional, communication and literacy skills. Non-optical low vision devices and optical and tactile graphics technologies are some of the assistive technologies used by visually impaired students in today's…

Students with visual impairments have the same span of cognitive abilities as their peers, but science instruction typically relies very heavily on vision. The preponderance of visually oriented and visually complex science concepts poses significant challenges to learning among students with visual impairment. This study is engaging, hands-on…

The Periodic Table of Elements is a valuable resource for chemists and all kinds of STEM professionals. However, it can be initially overwhelming and intimidating to some students. This hands-on lesson introduces abstract concepts in the periodic table through a tangible experience with simple toys and household objects. Students collaborate and…
