Description¶
A lesson-level instructional pattern in which learners classify physical models (paper-clip arrangements), draw particulate representations of solids, liquids, gases, elements, compounds and mixtures, view dynamic animations, build play-dough models, and share and discuss representations. The article states that "multiple representational tasks, combined with collaborative group work, discussion, and self-reflection, provided preservice teachers an opportunity for generating more scientific representations of matter." The instruction lasted three class periods in two phases.
Design Implications¶
Context¶
Requirements¶
- Tasks must span the macroscopic, submicroscopic, and symbolic representational levels
- Whole-class discussion to reach consensus views about representations and definitions
Constraints¶
- The article notes the instruction gave no special attention to distinguishing homogeneous from heterogeneous mixtures, which it links to weaker gains on physical composition
Target Learners¶
- preservice chemistry teachers
- third-year students in a five-year teacher education program
Learning Goals¶
- understanding the structure of matter at three physical states
- classifying elements, compounds, pure substances, and mixtures at different representational levels
Claims¶
- Multiple Representations Instruction Increased Appropriate Classifications [+M]
- Physical Composition Hardest Aspect Homogeneous Heterogeneous Confusion [~M]
