Recognize and Avoid These 7 Common Teaching Fallacies

Teaching is complex work, and we—like all professionals—use shortcuts to manage the complexity. We make assumptions and form judgments in real time, even when we may not have complete information. We use observations and clues to assess and adjust our instruction and anticipate and manage behavior. However, sometimes what we think we are seeing is not what is actually happening.

The cues and strategies on which we depend can be flawed, and priority choices we make may be limiting the learning we intend. We might think of these common assumptions, perceptions, and conclusions as teaching fallacies. They may be practiced with good intentions, but they can still get in the way of learning. Let’s explore seven common teaching misconceptions, the consequences they can produce, and how we might overcome them.

The compliance fallacy.
Students may be quiet and doing as they are told. They may be looking at us and following instructions. Yet, what we are saying may be going in one ear and out the other. It is said that we can demand our students’ presence in seats, but learning is voluntary. Compliance might be a starting point, but learning that is captured and retained is more likely to result when students find relevance, utility, and meaning in what they are learning. The resulting commitment is a far better path to learning than demanded compliance.

Insight: Learning requires a level of structure and order, but compliance is often not adequate for learning to occur. Learning requires interaction, reflection, and sensemaking—actions not assured when compliance is the only driver.

The activity fallacy.
Learning often comes through activities. However, not all activities result in learning. Students may participate in enjoyable experiences without learning and may be active without gaining insight and understanding. The experiences we design for students must begin with a focus on and lead to learning. If they don’t, they serve little purpose.

Insight: Activities need to serve learning, not just entertain. Worthy activities are tightly tied to, support, and lead to learning outcomes.

The engagement fallacy.
We might think that if students are smiling, looking at us, and participating, then they must be learning. Yet, multiple studies have shown that adults tend to significantly overestimate student engagement. In fact, students are often skilled at looking engaged when their minds are a million miles away. On the other hand, students who may not appear to be engaged may be thinking deeply, considering implications, and making connections in their learning.

Insight: We must do more than assume engagement based on nonverbal signals. Checking for understanding, structuring active participation, and asking for feedback can offer more reliable evidence.

The learning retention fallacy.
If students understand today’s lesson, we might think we can move forward with confidence that they will be able to remember and use what they have learned. However, this can be a flawed assumption. Initial learning may have yet to be transferred into long-term memory and, consequently, can quickly be lost.

Insight: We need to follow new learning up with opportunities for students to practice and develop long-term recall if we want them to retain what they learn.

The first idea fallacy.
We can become overly enamored with the first idea we have, what feels like an obvious solution, or an action that will release the pressure we feel. Yet, ignoring alternatives, overlooking assumptions, failing to iterate, and discounting implications can be expensive in time, effort, and outcomes. This approach stymies our creativity, limits our flexibility, and can deprive us of promising alternatives that would better serve the needs of our students.

Insight: Taking time to consider alternatives, explore options, and press our thinking can make the difference between just pushing through and finding new ideas, fresh approaches, and solutions that best serve our goals.

The gut feeling fallacy.
Intuition can be accurate, but it can also ignore factors that are not apparent or known to us. We can risk losing time and wasting energy when we rely on our gut feelings alone. We can even make the situation worse when we depend on perceptions and assumptions over data and evidence. Of course, solid evidence is not always available to us, and sometimes we have no alternative than to fall back on our gut feelings. However, we need to be cautious and avoid overdependence on what we assume when we really do not know.

Insight: Intuition can be useful in many circumstances. However, gut feelings informed by evidence hold the greatest promise for finding answers and designing interventions.

The coverage fallacy.
We may feel pressure to cover everything in the curriculum, especially as the end of the grading period, semester, or school year looms. However, hurrying through concepts, skimming over content, and lightly touching skills accomplishes little when learning is our goal. We may need to prioritize and even skip some elements. However, if the time we recoup results in the learning of important concepts, content, and skills, the tradeoff will be well worth it.

Insight: Remember that what counts most is what students learn, not what we teach. Pacing matters, but pacing needs to respond to learning progress, not just the week of the year.

Many of these fallacies may seem obvious and familiar. A simple reminder to avoid them may be all you need. Of course, the list is not exhaustive; you may also want to add to it. When you do, please share your insights with your colleagues.
