Writing Prompts Help Improve Expression of Conceptual Understanding in Chemistry

Area of Science:

• Chemistry Education
• Science Communication
• Educational Psychology

Background:

• Secondary school students frequently make specific writing errors in chemistry assessments.
• Common mistakes include poor punctuation, missing key concepts, incomplete reasoning, unclear pronoun references, and incorrect use of connectives.
• Addressing these language-based issues is crucial for accurate scientific communication.

Purpose of the Study:

• To develop and evaluate interventions aimed at improving the writing performance of secondary school students in chemistry assessments.
• To identify frequent writing errors and formulate targeted strategies to mitigate them.
• To assess the effectiveness of a written prompt, bonus points, and language support in enhancing chemistry writing.

Main Methods:

• Document analysis of student chemistry tests to identify common writing errors.
• Development of five key writing strategies: punctuation, key components, reasoning, antecedents, and connectives.
• A two-part intervention study involving a written prompt, bonus points, and language support materials.

Main Results:

• A written prompt significantly improved student writing performance by increasing awareness of common errors.
• The addition of bonus points and language support further enhanced writing quality in chemistry assessments.
• The intervention effectively addressed issues like punctuation, reasoning, and the use of connectives.

Conclusions:

• Student writing performance in chemistry assessments can be effectively improved through targeted interventions.
• Simple strategies like written prompts, language support, and positive reinforcement (bonus points) are beneficial.
• Enhancing students' awareness of common writing pitfalls is key to improving scientific communication skills.
