Process Science Instruction (Conceptual Change)

BENEFITS

---

• Process science instruction helps students think and act like scientists, which strengthens their understanding of content, skills, and the nature of science.

 

• Explicit teaching and practice of science process skills (e.g., graphing, experimental design, data interpretation) improves students’ performance in later science courses.

 

• Inquiry and “learning by doing” deepen conceptual understanding.

 

• Hands-on and inquiry-based science increases engagement, curiosity, and persistence.

 

• Teachers often report increased satisfaction and sense of impact as students take more ownership, engage in richer discourse, and demonstrate deeper understanding. link

 

 

 

How To

---

1. Identifying Alternative Conceptions: Teachers need to identify the alternative conceptions or misconceptions that students hold about a specific topic or concept. Instruction begins by eliciting students’ preconceptions (e.g., through prediction, drawing, discussion) and making them explicit in the classroom community.

 

2. Engaging in Cognitive Conflict: Students are presented with information or experiences that challenge their existing beliefs, leading to cognitive conflict. Teachers then design experiences (demonstrations, investigations, simulations) that challenge inadequate ideas, support sense-making, and introduce scientific explanations that are understandable and useful to students.

 

3. Facilitating Restructuring: Teachers then guide students through activities and discussions that help them reevaluate and restructure their understanding based on the new information, resolving the cognitive conflict.

 

4. Providing Opportunities for Practice and Reflection: Students are given opportunities to practice and apply the new understanding, as well as reflect on the changes in their thinking. Students are given time and structured discourse to compare explanations, weigh evidence, and reflect on how and why their thinking is changing, often through models such as the Generative Learning Model or similar sequences.

 

5. Uncovering student knowledge and preconceptions on topic,  engage in activities, events, or instruction that “calls into question” beliefs and original perceptions. link

SAMPLE ACTIVITIES

---

• Heat and temperature (ELE) Present two metal blocks at different temperatures that end at the same temperature when in contact, then ask students to explain “where the heat went,” collecting “heat moved into the colder block” vs “the heat disappeared” responses to reveal “heat as stuff.” Then introduce particle-motion simulations or role-play where students act as particles speeding up/slowing down, narrating heat as “energy in transit due to temperature difference.”

 

• Genetics (MS/HS) Have students first draw “what a gene is” and “how a gene makes a trait,” then sort the drawings into “gene is a thing you inherit” vs “gene is something that does something” to surface material views. Follow with a guided modeling task in which students construct a gene → RNA → protein → trait mechanism (e.g., for sickle cell or lactase persistence) emphasizing actions: transcribe, translate, fold, bind. link

 

 

 

 

 

 

CHALLENGES

---

• Many teachers feel less confident in their science content knowledge and inquiry pedagogy, so they default to reading, worksheets, and “right answer” questioning instead of open investigation.

 

• Beliefs that students “aren’t ready” for authentic inquiry or can’t grasp the nature of science can inhibit sustained use of process‑focused instruction, even though research shows students of all ages can learn these ideas.

 

• Inquiry, project-based, and NOS-rich lessons take more class time for planning, investigation, discussion, and reflection than traditional coverage.

 

• High‑stakes testing and tightly specified standards can push teachers toward test-prep and discrete content objectives.

 

• Lack of lab materials, equipment, flexible space, and technology.

 

• Managing group work, long-term projects, safety, and diverse learners during inquiry poses real classroom management challenges. link

 

 

WHAT NOT TO DO

---

• Do not just “turn them loose” to figure everything out with minimal explanation or support.

 

• Do not start a unit with open inquiry before students have core ideas and vocabulary.

 

• Do not assume that doing lots of experiments automatically builds deep understanding.

 

• Do not overemphasize hands‑on work at the expense of reflection, representation, and explanation; students need time and prompts to talk, write, and draw about what their results mean.

 

• Entrenched misconceptions persist unless they are deliberately surfaced and challenged with evidence.

 

• Do not move on when students’ explanations are clearly inconsistent with the target model.

 

• Do not design investigations with too many variables, steps, or new representations at once; excessive complexity can overwhelm working memory.

 

• Do not mix colloquial and technical meanings of key terms (e.g., “theory,” “hypothesis”) without clarification; language confusion adds unnecessary cognitive load.  link
