When it comes to learning and development, leveraging a student's pre-existing knowledge base is not only beneficial but also considered a best practice. This strategic approach is often referred to as "building on prior learning," "capitalizing on previous knowledge," or more often, "scaffolding."
Scaffolding, a term coined by educational psychologist Lev Vygotsky, serves as a metaphor in educational theory for the temporary supports that a teacher provides to help students to accomplish a task that they would not be able to complete independently. In essence, it's about building on a student's existing knowledge to help them reach new heights.
Building on Existing Knowledge: The Why and How
Before delving into the specifics of how to build on a student's existing knowledge, it's crucial to understand why this approach is so vital.}
Research has consistently shown that students learn more effectively when they can connect new information to what they already know. This process, known as 'cognitive anchored instruction,' helps students to process and retain new information more effectively.
Enhancing Understanding
Building on prior knowledge enhances students' understanding and tempered with effective strategies, it can be a powerful tool for critical thinking and problem-solving. For instance, when introducing a new mathematical concept, a teacher could ask students to share what they already know about similar concepts, thereby scaffolding their learning.
This approach allows students to see the interconnectedness of concepts, forming a robust educational foundation, making future learning more meaningful and less daunting.
Promoting Confidence and Engagement
By recognizing and valuing students' prior knowledge, educators can foster a sense of accomplishment and self-efficacy. Students begin to see themselves as active participants in their learning journey, enhancing their engagement and motivation.
A concrete example could be asking students to share their understanding of a topic before introducing new content. This not only helps teachers assess students' existing knowledge but also makes students feel heard and valued, thus fostering engagement.
Scaffolding Techniques in Education
There are numerous techniques educators can employ to build on students' existing knowledge. Here, we will explore a couple of the most effective ones:
Remember, the goal is not to create dependent learners but to empower them with strategies they can use independently in the future.
inquiry-based Learning
Inquiry-based learning is built around the idea of student-centered learning. It encourages students to ask questions, explore, and solve problems independently or in groups. It's an excellent scaffolding technique as it builds upon students' existing knowledge and curiosity.
For example, asking students to explore and answer questions about a topic before introducing didactic instruction allows them to activate and build on their prior knowledge.
Explicit Instruction and Guided Practice
Explicit instruction combined with guided practice is another powerful scaffolding technique. Explicit instruction involves clearly explaining new concepts, showing step-by-step demonstrations, and providing immediate feedback. Guided practice, on the other hand, encourages students to apply what they've learned under the teachers' watchful eye.
This approach allows teachers to tailor instructions based on students' existing knowledge, gradually withdrawing support as students' independence grows.
In the fast-paced, ever-changing landscape of education, it's easy to get carried away with introducing new content. However, it's crucial to remember the importance of leveraging students' existing knowledge base. By effectively scaffolding learning, we can help our students not only to grow academically but also to develop into confident, resilient, and lifelong learners.
