Tips to help you correctly gauge the level for every class, every time

As a subject expert, pitching lessons in a way that will help a particular class is a constant challenge.
Early in our teaching careers, we can inadvertently overwhelm students in an effort to incorporate everything connected with the lesson title, from practical work and related topics to real-world science.
We are trying to help our students thrive, but when we pitch a lesson at too high a level, we risk losing some of them along the way. As students struggle to keep pace their understanding falters, leaving you feeling stretched as you attempt to support everyone at their own individual level.
Pitching correctly isn’t about lowering expectations; it’s about sequencing knowledge carefully, understanding your learners and using deliberate checks for understanding. You can keep your lessons engaging while supporting all your students with the following key considerations.
Consider the curriculum
Public assessments across the UK and Ireland provide a specification outlining the content to be assessed and the skills students are expected to develop, so use this document to plan your lessons in coordination with other resources. Before you begin to plan, ensure you have a clear understanding of what’s required so you can prioritise essential knowledge and keep challenges at an appropriate level. Your school will give you a scheme of learning and suggest content, and don’t be afraid to ask your more experienced colleagues for their advice, too.
At the same time, you should avoid overloading working memory by introducing too much new material at once.

Check for prior learning
It’s impossible to help students build on their foundation of knowledge if you’re not totally certain of what they know. The science curriculum builds progressively from primary school through to post-16. As a classroom teacher, you need to understand what your students have studied and how it connects to current content.
Retrieval activities such as starter questions, short quizzes or cold-calling can strengthen retention and highlight gaps; for example, with particle diagrams, try these knowledge checks. If their prior knowledge is insecure, students will struggle with new content. Assess this early and you can adjust your starting point.
Students also develop preconceptions based on everyday experiences. Link learning to real-life contexts to reveal misconceptions, then challenge inaccurate ideas and help them build stronger foundations.

Use your school’s data
Use the student data your school collects to find out more about the wider picture. You’ll find information on prior attainment, reading age and attendance, as well as SEND, EAL or pupil premium status. Although this can feel overwhelming, it can be invaluable. Being familiar with SEND profiles will help you anticipate specific barriers and suggest strategies. Regardless of whether classes are set by prior attainment, it is important to know who may need additional support or tasks to stretch understanding.
Students with poor attendance will find it harder to access new content. To help fill knowledge gaps, provide textbooks or knowledge organisers to encourage independence without reducing the challenge. There are plenty of tips in the article, Locked-out learners.
Reading ability is another key factor. Research suggests the average reading age of a GCSE exam paper is 15 years and seven months. Get students to read aloud when possible and give them glossaries and comprehension activities to improve their understanding of demanding material; try some of the activities in the Literacy for science teaching collection. Breaking down exam questions into bite-size chunks can really help.

Teaching to the top
Teaching to the top isn’t just about teaching the prior high attainers in the classroom. You should maintain high expectations for all students, regardless of what they’ve achieved up to this point. Keep the curriculum ambitious but make sure all learners can access it.
You can use scaffolding techniques to do this. They’ll help students engage with challenging content while developing independence over time. Scaffolding makes complex thinking manageable without simplifying the curriculum and you can gradually remove it as confidence increases.
Effective strategies include:
• Dual coding (diagrams and concept maps)
• Sentence starters and connectives
• Knowledge organisers
• Clear success criteria
• Partially completed examples (backwards fading)
• Live worked examples
• ‘I do, we do’ tasks
• The chunking technique
Is everyone on the same page?
Before moving to independent work, you can avoid misconceptions and confusion – which lead to disengagement – by testing students’ understanding of the work so far. Effective strategies include:
- Multiple-choice questions designed with misconceptions and distractors
- Mini whiteboard quizzes
- Cold-call questioning to sample understanding across the class
- Asking students to summarise their learning
- Targeted questioning: probe the depth of understanding, encourage precise scientific language and rephrase questions where necessary.
This responsive approach will help you pitch lessons appropriately and ensure no one gets left behind.
Practical work
Practicals are a key component of science teaching and can strengthen understanding, but practical work must be purposeful. When expectations are unclear, it can widen gaps. Be clear about the intended focus, whether it’s experimental design, accurate measurement, data recording or application of theory.

Model procedures beforehand and question students during each step. If students are struggling with cognitive overload, you may find it more effective to tackle each stage as a class. Dual coding of instructions, such as pairing equipment names with images, will make the topic even more accessible.
