Relational Scaffolding Enhances Children’s Understanding of Scientific Models

Abstract

Models are central to the practice and teaching of science. Yet people often fail to grasp how scientific models explain their observations of the world. Realizing the explanatory power of a model may require aligning its relational structure to that of the observable phenomena. In the present study, we tested whether relational scaffolding—guided comparisons between observable and modeled events—enhances children’s understanding of scientific models. We tested relational scaffolding during instruction of third graders about the day/night cycle, a topic that involves relating Earth-based observations to a space-based model of Earth’s rotation. Experiment 1 found that participants ( N = 108) learned more from instruction that incorporated relational scaffolding. Experiment 2 ( N = 99) found that guided comparison—not merely viewing observable and modeled events—is a critical component of relational scaffolding, especially for children with low initial knowledge. Relational scaffolding could be applied broadly to assist the many students who struggle with science.

How Can Cognitive-Science Research Help Improve Education? The Case of Comparing Multiple Strategies to Improve Mathematics Learning and Teaching

“…Further, how do teachers’ beliefs, such as their self-efficacy for helping all students learn challenging mathematics, impact how they use comparison, and do curriculum and professional-development materials such as ours change teachers’ beliefs? How can we integrate insights from using comparison to promote science learning (e.g., comparing observable and modeled events; see Jee & Anggoro, 2019) with insights from mathematics learning?…”

Abstraction: An alternative neurocognitive account of recognition, prediction, and decision making

“…Also, it is important to specify how reflection integrates modality-specific abstractions into multimodal abstractions and how awareness of abstraction processes underlies categorical predication. Learning research shows that guided and reflected upon relational processing generates abstraction in different domains (Jee & Anggoro 2019;Papageorgiou et al 2016).…”

Can a Domain‐General Spatial Intervention Facilitate Children’s Science Learning? A Lesson From Astronomy

“…Their training, however, taught these skills explicitly within the context of chemistry. Also illustrative of STEM‐situated spatial interventions is research by Jee and Anggoro (2019) who incorporated Earth‐ and space‐based perspective taking in their use of relational scaffolding during astronomy model‐based learning. They found this type of relational scaffolding was supportive of children’s learning.…”
