The effects of generating examples on comprehension and metacomprehension

Area of Science:

• Educational Psychology
• Cognitive Science
• Science Education

Background:

• Learners frequently use examples to enhance understanding, with prior research indicating benefits for both viewing and generating examples during declarative learning.
• However, the efficacy of self-generated examples for improving comprehension of expository science texts remains less explored.
• This study investigates the impact of example generation on comprehension and comprehension monitoring in undergraduate science education.

Purpose of the Study:

• To determine if generating examples improves comprehension and comprehension monitoring in undergraduate science students.
• To compare the learning gains associated with different levels of engagement in example generation and evaluation.

Main Methods:

• A pre-post design was employed with undergraduate science students.
• Participants completed readings and practice tests, with some groups additionally generating examples and/or evaluating their quality with feedback.
• Comprehension and comprehension monitoring were assessed using application-based test questions.

Main Results:

• All students showed overall comprehension improvement, but those who generated examples without evaluation had minimal learning gains.
• Students who evaluated the quality of generated examples demonstrated the most significant learning gains, particularly on application-based assessments.
• While overconfidence decreased across conditions, no significant differences in comprehension monitoring were observed between groups.

Conclusions:

• The effectiveness of example generation for learning is contingent on the learner's engagement, with evaluation and feedback enhancing benefits.
• Relying solely on generating examples may not yield substantial learning improvements compared to activities involving critical evaluation.
• These findings challenge the assumption that example generation alone is universally beneficial for learning complex scientific concepts.
