Concept Maps for Improved Science Reasoning and Writing: Complexity Isn't Everything

Area of Science:

• Educational Psychology
• Scientific Communication

Background:

• A common belief is that complex concept maps signify advanced knowledge and expert thinking.
• This study investigates concept maps used in scientific writing and reasoning.

Purpose of the Study:

• To challenge the pervasive notion that concept map complexity correlates with expertise.
• To examine how concept maps are used by undergraduate thesis writers to structure research and arguments.
• To assess the relationship between concept map revisions and the development of scientific reasoning and writing skills.

Main Methods:

• Undergraduate students utilized concept maps instead of traditional outlines for research scope definition and argument construction.
• Concept maps were generated at the semester's start, revised post-peer review, and again at the semester's end.
• Analysis focused on changes in map complexity and correlation with writing and reasoning skill development.

Main Results:

• While some students increased concept map complexity, a significant portion simplified their maps.
• No correlation was found between increased concept map complexity and improved scientific reasoning or writing skills.
• Map simplification may indicate developing expert-like thinking as understanding deepens.

Conclusions:

• Concept map complexity is not a reliable indicator of knowledge or expertise in scientific writing.
• Concept maps can be a flexible tool, adapting to diverse student needs in academic settings.
• Simplification of concept maps can reflect a more nuanced understanding and advanced cognitive processing.
