17.3 Questioning Strategies and Conceptual Change
Key Takeaways
- Misconceptions are not gaps but competing explanations that have worked for the student, so simply telling the correct answer usually leaves the misconception intact and available on the next assessment.
- The conceptual-change cycle is elicit, confront, resolve: surface the existing idea, provide an experience the idea cannot explain, then guide construction of an evidence-consistent explanation.
- Wait time of three to five seconds after a question and again after a student response substantially increases response length, the number of students who volunteer, and the incidence of student-to-student reasoning.
- Open questions with more than one defensible answer, plus follow-ups such as "What is your evidence?" and "How could we test that?", produce higher-level thinking than questions with a single recall answer.
- Bloom's taxonomy is a planning tool for ensuring questions span recall through creation, not a ranking in which lower levels should be skipped — recall questions are appropriate for establishing shared facts before analysis begins.
Why Telling Does Not Work
Competency 021 names two expectations that belong together: understanding "common misconceptions in science and effective ways to address them," and using "questioning strategies to elicit higher-level thinking." They belong together because questioning is the primary tool for surfacing and dislodging misconceptions.
A misconception is not an empty slot in a student's mind. It is a working explanation that has predicted the student's experience well enough to survive. A child who has never seen an object fall in a vacuum has excellent everyday evidence that heavier things fall faster. Simply announcing that they fall at the same rate adds a school fact alongside the lived belief; under pressure on a test, the lived belief usually wins.
The Elicit-Confront-Resolve Cycle
The research-supported sequence for conceptual change has three steps:
- Elicit. Surface the existing idea before instruction. Use a prediction ("What will happen when…?"), a drawing prompt ("Draw where the tree's extra mass came from"), a diagnostic multiple-choice question with misconception-based distractors, or a KWL chart. The purpose is diagnostic, and the teacher must respond neutrally so students reveal what they actually think.
- Confront. Provide an experience or data set the existing idea cannot explain. This is the pivotal step and the one most often skipped. The discrepant event must be observable, unambiguous, and directly contradictory — a demonstration that merely illustrates the correct idea will not do the work.
- Resolve. Guide students to construct and articulate the new explanation in their own words, then apply it to a fresh situation to confirm the change transferred.
High-Frequency Grades 4-8 Misconceptions
| Misconception | Accurate idea | Confronting experience |
|---|---|---|
| Seasons are caused by Earth's changing distance from the Sun | Axial tilt changes the directness of sunlight and day length | Model insolation with a flashlight at different angles on graph paper and count illuminated squares; note that Southern Hemisphere summer occurs when Earth is nearest the Sun |
| Plants get their mass from the soil | Most added dry mass comes from atmospheric CO₂ | Mass the soil and the plant before and after weeks of growth; plant gain far exceeds soil loss |
| Electric current is used up by a bulb | Charge is conserved; energy is transformed | Measure current with an ammeter on both sides of the bulb and find the readings equal |
| Heavier objects fall faster | Without air resistance all objects accelerate at g | Drop a flat sheet and a book, then crumple the sheet and repeat |
| Cold flows into warm objects | Thermal energy flows from warmer to cooler | Track temperatures of both objects over time; the warm object cools as the cool one warms |
| The Moon's phases are caused by Earth's shadow | Phases result from the changing viewing angle of the sunlit half | Model with a lamp, a ball, and a student's head at the center; note that a shadow event is an eclipse and is rare |
| Rocks and mountains are permanent | Rock is continuously cycled and landscapes change | Stream table erosion in minutes; examine weathered limestone on the campus |
| Evolution means individual organisms change to adapt | Populations change in allele frequency across generations; individuals do not evolve | Bean-and-toothpick predation simulation showing shifting population composition without any individual changing |
Notice the pattern: each confronting experience is a measurement or observation the student can make, not an assertion by the teacher. That is what makes the cycle work.
Question Types
| Type | Purpose | Example (erosion unit) | When to use |
|---|---|---|---|
| Closed / recall | Establish shared facts and vocabulary | "What word names the movement of soil by water?" | Briefly, before analysis |
| Open | Invite multiple defensible answers | "What could explain why this bank eroded more than that one?" | Core of discussion |
| Probing | Push for reasoning behind an answer | "What is your evidence for that?" | After any claim |
| Redirecting | Distribute thinking across the class | "Marcos said the slope matters. Who can add to or challenge that?" | To build discourse |
| Metacognitive | Make thinking visible | "What would have to be true for your claim to hold?" | End of an investigation |
Using Bloom's taxonomy as a planning check ensures questions span the range:
| Level | Sample stem | What it elicits |
|---|---|---|
| Remember | What is the definition of deposition? | Recall |
| Understand | Why did the channel deepen over time? | Comprehension |
| Apply | Predict where sediment will settle if we increase the slope. | Transfer |
| Analyze | Compare the channel shape at low and high flow. What pattern do you see? | Decomposition |
| Evaluate | Which erosion-control design is more effective, and what is your evidence? | Judgment with evidence |
| Create | Design an investigation to test how vegetation affects erosion rate. | Synthesis |
Bloom's levels are a planning tool, not a hierarchy in which the lower levels are inferior. A class cannot analyze a pattern in erosion data before it shares the vocabulary for describing one.
Wait Time
Wait time I is the pause after the teacher asks a question. Wait time II is the pause after a student finishes speaking, before the teacher or another student responds. Typical classroom wait time is under one second. Extending both to three to five seconds produces measurable changes: student responses get longer, more students volunteer, students support answers with evidence unprompted, and the number of student-to-student exchanges increases.
Wait time II is the one teachers most often omit and the one that most changes discourse, because the pause signals that the answer is being considered rather than immediately evaluated.
Discourse Moves That Sustain Thinking
- Revoice — "So you're saying the darker soil absorbed more energy. Is that right?" This confirms understanding and gives the class a clearer version to respond to.
- Ask for evidence — the default follow-up to every claim, correct or incorrect.
- Invite disagreement productively — "Who sees it differently?" normalizes competing explanations, which is essential if misconceptions are to be voiced at all.
- Avoid the funnel. "Guess what I'm thinking" sequences of narrow questions that lead to the teacher's sentence produce compliance, not reasoning.
- Withhold evaluation during elicitation. Saying "good" to the first correct answer ends the thinking for everyone else. Neutral acknowledgment — "Thank you, what else?" — keeps the space open.
The through-line is that questioning is diagnostic before it is instructional. A teacher who knows what students actually believe can design the confronting experience that changes it; a teacher who only knows whether students can repeat the right answer cannot.
Most students in a class predict that a heavy ball will hit the ground before a light ball dropped from the same height. Which teacher response best follows the conceptual-change cycle?
A teacher asks an open question about why one stream bank eroded more than another and then waits four seconds before calling on anyone, and waits again after each student finishes speaking. What is the most likely documented effect?
A student writes that the Moon has phases because Earth's shadow falls on it. Which instructional response is most consistent with the framework's expectations for addressing misconceptions?
