An Exploration of Spatial Visualization Skills: Investigating Students' Use of 3D Models in Science Problems during...

Area of Science:

• Science Education
• Biochemistry
• Chemistry

Background:

• Spatial visualization and reasoning are crucial for success in science and engineering.
• Students often lack training in effectively using 3D models for learning.
• 3D models, like molecular kits, can aid in conceptualizing molecules in 2D and 3D.

Purpose of the Study:

• To investigate student techniques for conceptualizing biomolecules using 3D models.
• To identify strategies employed by successful students in spatial reasoning tasks.
• To explore the impact of 3D model utilization on understanding 2D and 3D representations.

Main Methods:

• Task-based, think-aloud interviews with undergraduate science and engineering students.
• Analysis of participant data to identify visualization techniques.
• Scoring and comparison of techniques used by successful and less successful students.

Main Results:

• Successful students utilized informal models to transition between 2D and 3D representations.
• Students who anchored their thinking in 3D models demonstrated deeper understanding.
• Starting with granular details aided inductive reasoning for 3D conceptualization.

Conclusions:

• Anchoring thinking in 3D models leads to more successful initial problem-solving.
• Effective 3D model use and spatial visualization training can improve molecule visualization in science.
• Implementing spatial visualization training can enhance students' problem-solving techniques in science curricula.
