Evaluating a school-based science program that teaches the physiological effects of nicotine

Area of Science:

• Neuroscience and Pharmacology
• Education and Public Health

Background:

• School-based drug prevention programs are crucial for public health.
• Educating students on the physiological and addictive effects of drugs like nicotine is a key component.
• Traditional methods may not fully engage students in understanding complex biological mechanisms.

Purpose of the Study:

• To evaluate the effectiveness of a novel school-based laboratory module using planarians to teach students about nicotine's physiological and addictive effects.
• To assess changes in knowledge regarding nicotine's impact across different grade levels (4th-12th) and demographics.

Main Methods:

• A laboratory module was developed where students observed nicotine-induced behaviors in planarians (flatworms).
• Two studies were conducted: one with 6th-12th graders using a 5-minute observation period, and a modified version for 4th-5th graders with a 1-minute period.
• Pre- and post-lab surveys assessed students' knowledge of nicotine's effects.

Main Results:

• Students across all grades (4th-12th) demonstrated a significant increase in knowledge about nicotine post-lab.
• Initial knowledge varied by grade, with 6th graders showing lower scores than 7th-12th graders, but all improved significantly.
• The lab effectively enhanced nicotine knowledge in urban, suburban, and rural 6th-grade settings.

Conclusions:

• Using planarian models provides an effective and engaging method for teaching students about the physiological and addictive properties of nicotine.
• This approach significantly improves scientific literacy regarding addictive substances in a diverse student population.
• The adaptability of the lab module across different age groups and settings highlights its potential for widespread implementation in drug prevention education.
