17 Instructor Prior Knowledge: Expert Blindspot
In teaching, one of the key challenges is recognizing and addressing the “expert blind spot.” This concept refers to the difficulty experts face in perceiving the struggles novices encounter when learning a new domain of knowledge. Often, experts forget the specific steps and processes they mastered over years of practice—steps that are now automatic for them. As a result, they may unintentionally gloss over critical foundational elements, leading to gaps in instruction and student confusion (Nathan, Koedinger, & Alibali, 2001).
Identifying the Expert Blind Spot
To bridge the gap between expert and novice thinking, instructors first need to become aware of where these blind spots might arise. Here are some strategies for identifying them:
- Analyze Student Struggles
Pay attention to patterns in student difficulties. Recurring issues in assignments, common questions, or repeated errors on assessments can signal areas where students are struggling to grasp fundamental concepts. These patterns might reveal steps or explanations that need to be made more explicit in instruction. - Review Pedagogical Research
Each discipline has its own learning challenges, and reviewing research specific to your field can help you anticipate where students might get stuck. Pedagogical studies often highlight common novice difficulties and offer insights into how to effectively teach core skills and concepts. - Consult Advanced Novices
Seek input from individuals who are closer to the novice experience, such as graduate students or recent alumni. They can provide a unique perspective on potential stumbling blocks, offering insights that experts, further removed from their initial learning stages, might overlook.
Addressing the Blind Spots
Once potential blind spots are identified, educators can take targeted steps to better support their students’ learning:
- Break Down Complex Tasks
Experts often compress multiple steps into a single action, but novices benefit from a step-by-step breakdown of tasks. For example, rather than assuming students know how to approach problem-solving in a discipline, model the entire process: define the problem, outline possible approaches, explain the reasoning behind each decision, and reflect on outcomes. This scaffolding gives students a clearer roadmap to follow. - Demystify Expert Thinking
One of the most effective ways to combat the expert blind spot is to “demystify” your mastery. Share your own learning journey with students, explaining the challenges and struggles you faced when you were first learning the material. This not only helps students see that mastery is a process but also promotes a growth mindset by showing that expertise develops over time through practice and persistence. - Provide Extra Practice Time
Novices require more time to apply and practice new skills. Building in extra time for guided practice, where students can attempt tasks with support and feedback, can help solidify their understanding. Flipped classroom models, where students are introduced to material before class and spend class time engaging in hands-on practice, are one way to maximize this practice time. - Encourage Peer Instruction
Instructors can use peer-to-peer learning to their advantage. Having more advanced students mentor or tutor novices can help bridge the gap between expert and beginner. Advanced students, while still building their own expertise, often remember the challenges of learning the material and can provide explanations that resonate with novices.
Acknowledging and addressing the expert blind spot is crucial for creating a learning environment that truly supports student development. By breaking down complex tasks, making expert thinking visible, and offering ample practice and peer support, instructors can help students bridge the gap between where they are and where they need to be. With these strategies, educators can better guide novices on their journey toward mastery, empowering them to build the skills and knowledge needed for success.
