Designing Activities to Teach Higher-Order Skills: How Feedback and Constraint Affect Learning of Experimental Design

Area of Science:

• Biology Education
• Educational Technology
• Cognitive Science

Background:

• Active learning and simulation-based activities enhance biology student learning, particularly higher-order skills.
• Optimal learning in these environments depends on specific activity features, which require further investigation.

Purpose of the Study:

• To investigate the impact of feedback and constraint on student learning within a simulation-based experimental design tutorial.
• To determine which features of active learning tools most effectively promote the acquisition of experimental design skills.

Main Methods:

• Developed three versions of the 'Understanding Experimental Design' simulation tutorial, manipulating feedback and constraint levels.
• Assessed student learning of experimental design using diverse evaluation methods.
• Analyzed the direct and indirect effects of feedback and constraint on learning outcomes.

Main Results:

• Direct positive correlation observed between the presence of feedback and student learning gains.
• Minor adjustments in task constraint demonstrated subtle and predominantly indirect influences on learning.
• Feedback emerged as a critical factor for enhancing skill acquisition.

Conclusions:

• Feedback is a crucial component for maximizing the impact of educational tools designed to teach higher-order skills.
• Instructional designers can adjust constraint levels within a certain range to optimize other pedagogical features, such as immediate feedback delivery and student engagement time.
• Prioritizing feedback in the design of active learning simulations is recommended for improved educational outcomes.
