What are Guided Discovery Problems?
Through intriguing puzzles to solve, structured hands-on activities, carefully worded leading questions, crucial hints, and just-in-time presentations of information, guided discovery problems escort students step-by-step through the discovery process, giving them a tantalizing taste of the most delicious part of science.
Why Use Guided Discovery Problems?
Guided discovery problems can be fun, which, all by itself, may be a good enough reason to use them. But, perhaps more important, well-designed guided discovery problems are nicely aligned with research findings on how students learn science.
As stated by the National Research Council (2000, Inquiry and the National Science Education Standards: A Guide for Teaching and Learning (more info) , p. 116-120):
- Understanding science is more than knowing facts.
- Students build new knowledge and understanding on what they already know and believe.
- Students formulate new knowledge by modifying and refining their current concepts and by adding new concepts to what they already know.
- Learning is mediated by the social environment in which learners interact with others.
- Effective learning requires that students take control of their own learning.
- The ability to apply knowledge to novel situations, that is, transfer of learning, is affected by the degree to which students learn with understanding.
How to Use Guided Discovery Problems
Guided-discovery problems can be incorporated into lecture, lab, and field courses. They are ideal cooperative learning activities. They also fit beautifully into the exploration phase of the learning cycle approach to teaching (Brown and Abell, 2007 ), and are especially effective when they are assigned before any lectures or readings on the topic. Because guided-discovery problems are time-consuming and foster deep learning, they are best used to teach course material that is especially important, conceptually difficult, or counter-intuitive.
In order to succeed, a guided-discovery problem must be adequately scaffolded (Hogan and Pressley, 1997; Hmelo-Silver and others, 2007 ) so that students remain within their "zone of proximal development," the zone between what they can do on their own and what they can't do, even with help (Vygotsky, 1978).
