What the science says

Short practitioner summaries focused on specific questions. Each brief follows the same structure so you can move quickly from what we know to what it means for your classroom.

How to read these. Briefs give evidence-informed grounding rather than a complete implementation package. They are published progressively and kept deliberately concise. The implementation guides translate them into first steps.

01Brief 01What is mathematics anxiety?

What we know

Mathematics anxiety is an emotional response to mathematics. It can involve feelings of tension, worry, or apprehension that arise when working with numbers or facing mathematical tasks. It includes emotional, cognitive, and physiological components, and it can appear before, during, or after mathematical activity.

Common misconceptions

That anxiety is the same as simply disliking mathematics.
That it only appears during high-stakes tests.

Classroom implications

Treat anxiety as something students experience, not a fixed trait they are.
Notice the situations that tend to raise it rather than labelling the student.

Reflection questions

When do I notice signs of anxiety in my classroom?
Which moments in a lesson seem to raise tension for students?

02Brief 02How is it different from low achievement?

What we know

Anxiety and achievement are related but distinct. A student can perform well and still experience significant anxiety, and a student can struggle with content without feeling anxious. Anxiety can interfere with performance, which makes it easy to mistake one for the other.

Common misconceptions

That anxious students are simply the ones who find mathematics hard.
That confident or high-achieving students are free from anxiety.

Classroom implications

Look beyond performance alone when identifying student needs.
Separate questions about understanding from questions about emotional response.

Reflection questions

Which of my students might be anxious despite achieving well?
How would I tell the difference between confusion and anxiety?

03Brief 03What happens in working memory during anxious moments?

What we know

Anxiety consumes cognitive resources. When students worry during a task, attention and working memory are partly occupied by the worry itself, leaving fewer resources for the mathematical thinking the task requires. This helps explain why capable students can underperform under pressure.

Common misconceptions

That anxiety only affects motivation.
That performance under pressure reflects true ability.

Classroom implications

Reduce unnecessary load during demanding tasks.
Consider whether time pressure is adding worry without adding learning.

Reflection questions

When do my students carry the heaviest cognitive load?
Where could I lower pressure without lowering expectations?

04Brief 04Can teachers cause or reduce mathematics anxiety?

What we know

Teachers play an important role, and classroom experiences are one of several pathways into mathematics anxiety. Anxiety is rarely caused by a single factor. Prior experiences, beliefs, family and cultural messages, and learning difficulties also contribute. Classroom environments and relationships can influence how students experience mathematics.

Common misconceptions

That mathematics anxiety is caused by poor teaching alone.
That nothing a teacher does can change a student's anxiety.

Classroom implications

Attend to the messages your classroom sends about mistakes, ability, and challenge.
Hold influence and humility together. You matter, and you are not the only factor.

Reflection questions

What messages about mathematics might students take from my classroom?
Which of those messages would I want to strengthen or change?

05Brief 05What does the evidence say about growth mindset?

What we know

Beliefs about whether mathematical ability is fixed or develops can shape how students respond to difficulty. Beliefs that ability is fixed can contribute to avoidance and anxiety. Communicating that understanding develops over time is helpful, while a slogan alone changes little without matching classroom practices.

Common misconceptions

That telling students to have a growth mindset is enough.
That praising effort regardless of strategy supports learning.

Classroom implications

Pair messages about growth with tasks, feedback, and time that make growth visible.
Focus feedback on strategy and progress rather than fixed ability.

Reflection questions

Do my practices match the messages I give about ability?
How do students see their own progress over time?

06Brief 06Retrieval practice and anxiety: help or harm?

What we know

Retrieval practice supports learning and memory. Its emotional effect depends on how it is used. Low-stakes, frequent retrieval can build confidence, while high-stakes, timed, or public retrieval can raise anxiety for some students. The format and climate matter as much as the activity itself.

Common misconceptions

That any form of testing harms anxious students.
That retrieval must be timed to be effective.

Classroom implications

Keep regular retrieval low-stakes and framed as practice.
Separate the learning benefit of retrieval from the pressure of grading and speed.

Reflection questions

How do my students experience routine quizzing?
Could I keep the retrieval and remove the pressure?

07Brief 07Assessment design and emotional responses

What we know

Assessment is one of the most frequently reported triggers of mathematics anxiety. Students cope better when they understand expectations, have opportunities to prepare, and can demonstrate understanding in more than one way. How feedback is framed after assessment also shapes the emotional experience.

Common misconceptions

That anxiety around assessment reflects lack of preparation only.
That reducing assessment is the only way to reduce its pressure.

Classroom implications

Clarify success criteria and offer low-stakes practice before assessment.
Frame post-assessment feedback around growth and next steps.

Reflection questions

What emotions might students feel before, during, and after assessment?
Which features of my assessments create the most pressure?

08Brief 08Mathematics anxiety across primary and secondary years

What we know

Mathematics anxiety can appear early and can develop along different pathways over time. It is not a single phenomenon. Topics, transitions, and changing expectations across year levels can each play a part. Understanding local patterns is often the first step towards meaningful support.

Common misconceptions

That anxiety only emerges in secondary school.
That a single approach fits every year level.

Classroom implications

Watch transitions and topic shifts that tend to raise difficulty and worry together.
Coordinate messages about mathematics across year levels where possible.

Reflection questions

When do I first notice anxiety in the students I teach?
How consistent are the messages students receive as they move through school?
