Effect of laboratory manual layout: does experiential learning benefit from authentic context?

Area of Science:

• Science Education
• Biochemistry Education
• Laboratory Pedagogy

Background:

• Experiential learning is key to practical laboratory education, fostering deeper understanding and real-world skills.
• A disconnect often exists between authentic laboratory contexts and higher education instructional methods.
• Traditional linear lab manuals may not fully leverage the potential of experiential learning.

Purpose of the Study:

• To investigate the impact of different laboratory manual layouts on student learning and engagement.
• To compare a traditional linear format with an authentic 'methods' section format.
• To assess changes in student confidence and perceived technical skills.

Main Methods:

• Developed two student laboratory manuals: one traditional, one with a distinct 'methods' section.
• Assessed student learning via summative assessments and online environment interaction.
• Collected data on student confidence and perceived technical skills through surveys.

Main Results:

• No significant differences were found in student assessment performance between the two manual formats.
• The 'methods' section layout led to significantly higher engagement with the online learning environment.
• Students reported a 21% increase in technical confidence and a 31% increase in perceived technical skills with the 'methods' section format.

Conclusions:

• Replicating an authentic context in laboratory manuals enhances experiential learning.
• The 'methods' section layout improves student engagement and self-perceived skill development.
• Contextualizing information within laboratory manuals is crucial for effective science education.
