In representation-rich domains such as organic chemistry, students must be facile and
accurate when translating between different 2D representations, such as diagrams. We …

This study investigated the development of representational competence among organic
chemistry students by using 3D (concrete and virtual) models as aids for teaching students …

This book establishes a new theoretical and practical framework for multimodal disciplinary
literacy (MDL) fused with the subject-specific science pedagogies of senior high school …

The current study, undertaken in the Sultanate of Oman, explored twelfth grade students'
common misconceptions in seven chemistry conceptual areas. The sample included 786 …

The case is made that, whilst all school-age students should appreciate the nature of and
relationship between the macro and submicro types of representation (what we call the …

The practices of argumentation have recently been upheld as an important need to develop
students' understanding of scientific concepts. However, the present education system in …

The purpose of the current study is to explore the impact of associating animations with
concrete models on eleventh-grade students' comprehension of different visual …

Concerns persist regarding high school students' chemistry learning. Learning chemistry is
challenging because of chemistry's innate complexity and the need for students to construct …

This paper proposes a model-based notion of 'submicro representations of chemical
reactions'. Based on three structural models of matter (the simple particle model, the atomic …

The central goal of this study was to examine the extent to which a teaching approach
focused on the interaction between macroscopic, submicroscopic, and symbolic levels of …
