Why PYP Inquiry Units Lose Momentum in the Middle

The first week of a PYP unit often feels full of possibility.

A strong provocation gets learners talking. The question board fills quickly. Students make predictions, challenge one another and notice connections the teacher did not plan.

The final week has a clear purpose too. Learners are preparing evidence of understanding, reflecting on how their thinking changed or deciding whether meaningful action should follow.

The middle is harder.

By week three, the original provocation has lost some of its energy. A few questions have been answered, others are too broad to investigate, and the summative task is getting closer. The teacher begins carrying more of the lesson because the inquiry needs somewhere to go.

The original Koncepts LinkedIn post calls this the “messy middle.” Neither of the two studies cited in the post identifies one universal week when inquiry stalls. They do, however, document conditions that can make PYP implementation difficult, including limited collaborative planning, rigid timetables, weak specialist involvement and planners that are not actively revisited.

What PYP Research Says About Sustaining Inquiry

The official IB PYP curriculum framework describes the programme as transdisciplinary, inquiry based and student centred, with responsible action at its core. It also places learner voice, curiosity and contribution at the centre of collaborative inquiry.

“Agency and self-efficacy are fundamental to learning in the PYP.”

Agency is not visible only when learners choose a topic. It is visible when their questions, misconceptions, evidence and decisions influence what happens next.

A study by Michael Savage and Susan Drake explored the experiences of 24 PYP educators across classroom, specialist, coordination and leadership roles. Participants generally valued the transdisciplinary framework, but raised implementation concerns involving timetabling, collaborative planning, specialist participation and the usefulness of the planner during teaching.

Nancy Macharia’s 2022 doctoral study interviewed seven homeroom and specialist educators at one international primary school. It identified collaboration, time, curriculum articulation and reflection as important conditions for integrating Approaches to Learning skills across transdisciplinary learning.

These qualitative studies do not prove that every PYP classroom experiences the same problem. They reveal something more useful for planning: inquiry becomes difficult to sustain when the structures around it cannot respond to learner thinking.

1. Broad Lines of Inquiry Never Become Real Investigations

A broad line of inquiry can create direction, but it cannot carry a unit by itself.

Consider the difference between these two prompts:

“What are the uses of water in our community?”

“What happens to the water after it leaves our school?”

The first invites learners to collect information. The second gives them a system to trace. They can map pipes, interview facilities staff, explore treatment processes, compare water use and discover questions that were not visible at the start.

This does not mean every line of inquiry must become a narrow factual question. Lines of inquiry are conceptual pathways connected to the central idea. The practical challenge is turning those pathways into investigations learners can enter.

A useful investigation usually has four qualities:

1. Learners can gather evidence from people, places, objects, records or data.

2. The answer is not completely known before the investigation begins.

3. The learning contributes to the central idea rather than producing disconnected facts.

4. The findings can create a new question, comparison or decision.

The local question makes the inquiry manageable. The conceptual return gives it depth.

The Koncepts PYP Unit of Inquiry Planning Guide explains how central ideas, lines of inquiry, concepts, assessment and student agency can work as one connected learning journey.

2. The Inquiry Cycle Becomes a Calendar

Inquiry cycles give teachers and learners a shared language for the learning process. Problems begin when each phase is assigned one week and completed only once.

Week one becomes tuning in. Week two becomes finding out. Week three becomes sorting out. The class moves forward because the calendar says it should, even when formative evidence suggests otherwise.

Real inquiry moves back and forth.

A new source may challenge an early assumption. Sorting information may expose a knowledge gap. A student question may require another period of finding out. Reflection may lead to a fresh investigation rather than the end of the unit.

The Savage and Drake study found that many participants treated the PYP planner more as an archival document than a living one. Teachers often used it during initial planning and returned to it after the unit, while relying on separate working documents during teaching.

That gap matters. A PYP planner is most useful when it records decisions made while learning is unfolding.

Instead of asking, “Which phase should we finish this week?”, ask:

1. What are learners currently trying to understand?

2. What evidence shows that their thinking has changed?

3. Which misconception is affecting the inquiry?

4. What knowledge or skill needs direct teaching now?

5. Which learner question could shape the next investigation?

A responsive planner does not signal weak preparation. It shows that formative assessment is doing its job.

3. Specialist Teachers Join After the Unit Is Designed

A unit is not genuinely transdisciplinary because the Art teacher creates a poster or the Music teacher finds a song connected to the topic.

Specialist contribution becomes meaningful when disciplinary knowledge changes how learners investigate, interpret or represent the central idea.

In the Savage and Drake study, most participants viewed collaborative planning as essential. One educator put it plainly:

“You can’t do it without it.”

The study also found that scheduling made collaboration difficult and that some specialist teachers were expected to fit into units already created by classroom teachers. This reduced their ownership of the planning process.

A short meeting before the unit begins can prevent this.

Clarify the central idea, identify what each discipline can contribute, plan one specialist experience for the middle of the unit and agree on the evidence of thinking the team will collect.

Specialists should not be used to decorate a theme. Their disciplines should help learners see something they could not see before.

4. The Week One Question Board Is Never Revisited

A question board can look like student agency without influencing the unit.

Learners add questions during the opening provocation. The teacher celebrates their curiosity. Then the board remains untouched while the planned activities continue.

By week three, bring those questions back and sort them into four groups:

1. Answered with evidence

2. Partly answered

3. Still open

4. New questions created by our learning

The important part is the justification.

What evidence allows a question to be marked as answered? Which assumption changed? Which new question connects most strongly to the central idea?

The class does not need to pursue every wondering. Teacher judgement still matters. Agency means learner thinking influences the route. It does not mean the teacher abandons curricular purpose.

Direct Instruction Can Strengthen Inquiry

Direct instruction is not the opposite of inquiry.

Learners sometimes need vocabulary, background knowledge, modelling or a clear explanation before they can investigate independently. A teacher may need to demonstrate how to read a graph, analyse a source, conduct an interview or use a scientific method safely.

Direct instruction supports inquiry when it responds to a visible need and returns responsibility to learners. It weakens inquiry when explanation replaces observation, questioning, evidence gathering and decision making for the rest of the unit.

Before stepping in, ask:

1. What learner evidence shows that this explanation is needed?

2. Will it help students pursue an existing question?

3. What will learners investigate, apply or decide afterwards?

The aim is not less teaching. It is teaching that keeps the inquiry moving.

A Practical Week Three Reset

When the energy begins to fall, the unit may not need another dramatic provocation. It may need a focused reset.

Use one planning session to complete five actions:

1. Revisit the central idea and ask learners what it means to them now.

2. Return to the original question board and sort the questions using evidence.

3. Examine formative assessment for misconceptions, gaps and emerging interests.

4. Select one manageable investigation that can move the inquiry forward.

5. Update the planner and record why the direction changed.

This routine reconnects the unit with its purpose while making learner thinking useful again.

What PYP Leaders Need to Protect

Some momentum problems cannot be solved by an individual teacher.

PYP leaders need to protect collaborative planning throughout the unit, give specialist teachers early access to the central idea and lines of inquiry, and allow enough timetable flexibility for investigations that do not fit into short subject blocks. Teachers also need permission to change the planner when evidence points in a better direction.

Macharia highlights collaboration, time, curriculum articulation and reflection as important support structures. Savage and Drake similarly argue that collaborative planning should continue throughout the school year because transdisciplinary learning is fluid.

Strong inquiry depends on classroom practice, but it also depends on the conditions a school creates around that practice.

Keeping the Middle Alive

The middle of a PYP unit will rarely look as polished as the completed planner.

Learners are revising theories. Teachers are interpreting evidence. Specialist perspectives are creating new connections. Some questions are fading while better ones are emerging.

That is not a planning failure. It is the point where responsive planning becomes visible.

A strong PYP inquiry unit keeps moving because the central idea remains clear, investigations remain manageable, formative assessment changes decisions and learners can see that their thinking matters.

Koncepts helps PYP teachers build resources around their own Programme of Inquiry, central idea and lines of inquiry.
