Summary In this episode of the Chalk Dust podcast, Nathaniel Swain and Rebecca Birch visit the classroom of Queensland primary school teacher, Rebecca Sloots, the first teacher to be featured on the Teach Like a Champion practice archive. By exploring checking for understanding (CfU) and checking for quality (CfQ), the hosts unpack effective teaching practices, focusing on explicit instruction, CFU techniques, and the importance of peer feedback. They explore how generative learning fosters deeper student engagement and discuss the unique challenges of applying explicit teaching strategies in humanities education. The conversation emphasises the need for responsive teaching and the value of questioning strategies that encourage multiple interpretations. The importance of addressing misconceptions is discussed, as well as fostering a culture of improvement, and the role of formative assessment in enhancing learning. The commentary points to the need for teachers to adapt their practices, embrace imperfection in the classroom, and set professional growth goals based on observed classroom dynamics. Mentioned resources and explainers Teach Like a Champion – Official site for Doug Lemov’s Teach Like a Champion techniques. It provides an overview of this framework of effective teaching practices – a set of techniques and a shared vocabulary that help teachers achieve dramatic results in the classroom. Reading Reconsidered – Information on Reading Reconsidered, a practical guide to rigorous literacy instruction by Doug Lemov and colleagues. This resource offers clear, actionable strategies to help all teachers strengthen students’ reading skills – from tackling more complex texts and close reading, to building vocabulary and reading stamina – so that students become confident, independent readers. A variation on Beck and McKeown’s Questioning the Author reading comprehension and interpretation strategy is scaffolded for teachers in this book. Explicit Direct Instruction (EDI) – Hollingsworth & Ybarra – Overview of the Explicit Direct Instruction teaching approach developed by John Hollingsworth and Silvia Ybarra. EDI is a highly structured, step-by-step method for delivering well-designed lessons, emphasising clear objectives, teacher modeling, guided practice, and continual checking for understanding to maximise student success. TAPPLE is a check for understanding protocol that is mentioned. Generative Learning – Explainer on generative learning theory, which encourages students to actively generate information and make connections between new material and their existing knowledge. It describes how strategies like summarising, teaching others, or drawing concept maps help learners engage deeply with content and create more durable understanding. Questioning the Author – Here is a recent post from Nathaniel on this very useful instructional approach for generating quality discussions about text. Devised by Margaret McKeown and colleagues, Questioning the Author involves asking initially broad and open-ended queries about what has been read, followed by more specific questioning to dive deeper into the author’s intentions. Checking for Understanding – Article on why teachers should continuously verify students’ understanding during lessons and how to do it effectively. It outlines techniques for real-time formative assessment – for example, probing questions (beyond yes/no), sampling multiple students’ responses, and using cold calling – so that instruction can be adjusted based on what students have or haven’t grasped. Cold Calling – Guide to the cold call technique, as popularised by Doug Lemov. This strategy involves the teacher calling on students unpredictably (rather than only volunteers) to answer questions. The article explains how cold calling keeps everyone attentive and accountable, normalises active participation from all pupils, and creates a more inclusive classroom where each student is expected to think and respond.

Summary In this episode of Chalk Dust, Rebecca Birch and Nathaniel Swain are joined by Kris Boulton, founder and CEO of Unstoppable Learning, to explore atomisation, an approach to instructional design that breaks complex learning into carefully sequenced, manageable elements. Drawing on classroom footage of Kris teaching algebra to primary and secondary students at Mastery Schools Australia, the discussion examines how precise explanations, minimally different examples and systematic checking for understanding can enable students to master mathematical concepts that initially appear well beyond their capabilities. Kris demonstrates how deliberate instructional design can remove unnecessary cognitive demands, allowing students to concentrate on exactly what they are learning. Through examples of expanding algebraic expressions, he explains why the selection and sequencing of examples matter, how to separate arithmetic from new mathematical procedures, and how mini whiteboards and immediate corrective feedback help teachers identify and address errors before moving forward. Central to his approach is the Penny Promise: if students give their attention and follow the instruction, the responsibility for their success rests with the teacher. Throughout the episode, Rebecca, Nathaniel and Kris explore the relationship between instructional design, cognitive load, student motivation and teaching expertise. The conversation extends beyond mathematics into broader questions about teaching sentence construction, selecting examples, managing instructional pace and the balance between explicit modelling and guided practice. Ultimately, the episode challenges teachers to consider how much more students might learn when every explanation, example and practice opportunity is designed with precision. Mentioned resources and explainers Kris Boulton Kris Boulton is an international teacher educator and education writer specialising in evidence-informed instructional design. He has contributed to England’s Early Career Framework and Ofsted’s Mathematics Inspection Framework, led teacher educator development at Teach First, and helped design Up Learn’s learning system. Unstoppable Learning Founded by Kris Boulton, Unstoppable Learning works with schools to improve mathematics instruction through a structured approach to instructional design known as atomisation. The organisation focuses on making complex learning accessible through precise explanations and carefully sequenced examples. Atomisation An approach to instructional design that breaks learning into a small number of fundamental elements, each requiring a particular form of explanation and sequencing. Kris argues that identifying these elements allows teachers to design instruction that minimises ambiguity and prevents predictable misconceptions. The Penny Promise Named after Kris’s early-career mentor, Penny Jones, the Penny Promise is a commitment to students that if they pay attention and follow the instruction, they will succeed. It places responsibility on the teacher to design and deliver instruction that makes success possible. Engelmann and Carnine – Theory of Instruction Siegfried Engelmann and Douglas Carnine developed Direct Instruction, a systematic approach to instructional design that informs Kris’s work. Their Theory of Instruction examines how examples, non-examples, transformations and carefully controlled variations can support accurate learning and generalisation. Minimally Different Examples Examples that change only one carefully selected feature at a time. By controlling what changes and what stays the same, teachers can direct students’ attention to the specific concept or procedure being taught. The Setup Principle A principle associated with Engelmann and Carnine’s instructional design in which irrelevant features of examples are kept constant while the feature being taught is varied. Kris discusses how this might apply to teaching sentence syntax without simult
Summary In this special in-person episode of Chalk Dust, recorded at researchEd Melbourne at Haileybury, Rebecca Birch and Nathaniel Swain are joined by Professor Anna Stokke, mathematician, educator and host of the Chalk & Talk podcast. Together they analyse classroom footage from Australian mathematics lessons, exploring how carefully sequenced instruction, explicit teaching and strong classroom routines support successful mathematics learning. Across examples including number bonds, subtraction algorithms, number lines and percentages, Anna explains why mathematics should be taught through deliberate sequencing, clear modelling and extensive guided practice. The discussion examines pair-share routines, scripted mathematics programs, mastery of mathematical symbols, the role of automaticity, and why concrete materials should be viewed as temporary scaffolds rather than permanent learning tools. Throughout the episode, Rebecca, Nathaniel and Professor Stokke discuss mathematics-specific pedagogy, instructional coaching, pedagogical content knowledge and the importance of ensuring every student has access to effective mathematics instruction. The conversation argues that explicit mathematics teaching is not passive or robotic, but highly interactive, intellectually demanding and built around giving students repeated experiences of success. Special thanks to Pat Sanders, Ollie Lovell and Brendan Lee for their help with this episode. Mentioned resources and explainers Professor Anna Stokke Anna Stokke is Professor of Mathematics and Statistics at the University of Winnipeg, adjunct professor and honorary co-director of the Science of Mathematics Lab at La Trobe University, and host of the Chalk & Talk podcast. Her work focuses on evidence-informed mathematics education and improving mathematics instruction. Chalk & Talk Podcast Anna Stokke’s podcast exploring evidence-informed mathematics education, instructional practice and educational research. Explicit Mathematics Program (EMP) A structured primary mathematics program developed by David Morkunas, Toni Hatton-Roberts, Ollie Lovell, and Dr Wendy Taylor. The program emphasises carefully sequenced instruction, explicit modelling, guided practice and cumulative review. Mastery Schools Australia An Australian special-assistance school network implementing explicit, carefully sequenced mathematics instruction. Number Bonds An early mathematics concept helping students understand part-whole relationships between numbers, providing foundations for later arithmetic and algebraic reasoning. Standard Algorithms Traditional written methods for operations such as subtraction. Anna argues that carefully sequenced instruction in standard algorithms develops procedural fluency while reinforcing place value understanding. Automaticity The ability to retrieve basic number facts rapidly and effortlessly. Automatic recall reduces cognitive load, allowing students to focus on more complex mathematical thinking. Concrete Materials Physical manipulatives used to introduce mathematical concepts. Anna argues they should be temporary instructional scaffolds rather than ongoing computational tools. Pedagogical Content Knowledge (PCK) The specialised knowledge teachers need to teach a particular subject effectively, including understanding misconceptions, sequencing and representations. Rebecca reflects on whether mathematics-specific instructional coaching deserves greater attention. Scripted Instruction Instructional programs that carefully sequence explanations, examples and practice opportunities.

Summary In this episode of Chalk Dust, Rebecca Birch and Nathaniel Swain are joined by Andrew McCrorey, an experienced educator and instructional leader at Monterey Secondary College in Victoria. Drawing on classroom footage from a secondary setting serving a highly disadvantaged community, Andrew demonstrates how explicit instruction, trauma-informed positive education and high expectations can work together rather than compete with one another. The discussion explores entry routines, co-regulation, secondary choral reading, gist statements, cold calling, participation as an equity issue, and the explicit teaching of behaviour expectations. Andrew explains how consistency across classrooms can function as an equity strategy, creating predictable environments in which students know what success looks like and teachers can focus on teaching rather than repeatedly resetting behaviour. Across the episode, Rebecca, Nathaniel and Andrew return to the idea that supporting students does not require lowering the bar. Instead, effective practice combines strong relationships, clear routines, deliberate participation structures and carefully sequenced academic support. The result is a classroom where students are both safe and challenged, and where literacy, behaviour and wellbeing are treated as interconnected parts of successful teaching. Mentioned resources and explainers Andrew McCrorey Andrew McCrorey is an educator with more than 20 years’ experience teaching in Australia and internationally. His work focuses on explicit instruction, behaviour support, trauma-informed positive education and improving classroom practice in complex educational settings. Monterey Secondary College Monterey Secondary College is located in Frankston North, Victoria. Andrew describes the school’s approach as combining evidence-informed teaching, trauma-informed positive education and consistency across classrooms to improve student learning and engagement. Trauma-Informed Positive Education A framework used at Monterey to support student regulation, relationships and readiness to learn. Andrew emphasises that trauma-informed practice is not about lowering expectations, but about raising expectations while providing the support students need to meet them. Four-to-One Positive to Corrective Feedback Andrew describes using a high ratio of positive to corrective feedback during routines such as lesson entry. Positive narration, greeting students warmly and acknowledging successful behaviour help establish a calm, predictable start. Entry Routines A tightly rehearsed lesson-entry process in which students know what materials to collect, where to go and what task to begin. Andrew explains how predictable entry routines support regulation, reduce bottlenecks and maximise learning time. Choral Reading Students read a text aloud together, following the teacher’s pacing and expression. Andrew uses choral reading in secondary English to build fluency, confidence, prosody and participation while allowing the teacher to hear and correct reading in real time. Gist Statements A summarising strategy in which students identify who or what a section is about, select key details and then condense the information into a single statement. Andrew uses this as part of a gradual release process to support comprehension and later writing. Cold Calling Andrew uses cold calling after students have had time to rehearse thinking through pair discussion. He frames participation as an equity issue, while also maintaining flexibility when a student is not ready to respond. Tracking the Speaker A universal attention routine used across the school. Students are explicitly taught to orient towards the speaker so that teachers can secure attention efficiently and maintain lesson flow. Explicit Teaching of Behaviour Rather than relying on broad classroom rules, Andrew teaches specific routines for situations such as arriving late. Students are shown what to do, what to expect, and how cons
Summary In this episode of Chalk Dust, Rebecca Birch and Nathaniel Swain are joined by STEM educator Amber Haven to explore what happens when explicit instruction meets genuinely engaging hands-on learning. Using footage from Amber’s middle-school STEM classroom, the discussion follows a lesson on neutral buoyancy, revealing how carefully designed routines allow practical investigations to remain cognitively demanding rather than descending into chaos. Amber demonstrates how retrieval practice, mini-whiteboards, Six Bricks, gesture, choral response and explicit behaviour routines work together to create classrooms where every student is thinking. Throughout the episode, Rebecca, Nathaniel and Amber discuss the importance of background knowledge, continuous checking for understanding, purposeful transitions, differentiation without lowering expectations, and designing practical activities that provide immediate feedback. The conversation highlights how high-quality classroom routines free students to focus on learning rather than logistics, making complex scientific concepts accessible through deliberate instructional design. Mentioned resources and explainers Amber Haven Amber Haven is a STEM educator with more than 16 years of classroom experience and a strong focus on translating cognitive science into practical classroom strategies. She has presented at ResearchED conferences across the United States and at the Thriving Educators Summit, and her work has been featured by The Learning Scientists and in Powerful Classrooms by Patrice Bain. Retrieval Practice Throughout the lesson, Amber demonstrates retrieval as an ongoing classroom habit rather than a single lesson component. Students repeatedly retrieve knowledge through mini-whiteboards, questioning, gestures, closed sentences and practical activities. Mini Whiteboards Mini-whiteboards allow every student to participate, provide immediate formative assessment, and make thinking visible. Amber discusses the routines required to use them fluently throughout a lesson. Six Bricks Six Bricks is a hands-on retrieval strategy that uses coloured Duplo bricks to sequence concepts, definitions or problems. Students retrieve vocabulary while constructing a coloured stack, allowing rapid checking for understanding and high levels of engagement. Continuous Checking for Understanding Rather than reserving checks for understanding for isolated moments, Amber embeds them throughout explanations, transitions and instructions, ensuring students remain cognitively engaged from beginning to end. Gesture and Dual Coding The episode explores how gesture, movement and simple physical cues support memory and retrieval—even with older students who may initially resist participating. Differentiation Amber demonstrates how differentiation can maintain common learning goals while adjusting the amount of work or level of support individual students receive, rather than lowering expectations or creating entirely different tasks. Practical Science with Explicit Instruction The discussion explores how carefully sequenced demonstrations, clear success criteria and explicit routines allow practical science lessons to remain focused on conceptual understanding rather than entertainment.

Summary In this episode of Chalk Dust, Rebecca Birch and Nathaniel Swain are joined by renowned mathematician, educator and founder of JUMP Math, John Mighton. Drawing on classroom footage from Canadian primary classrooms, John shares the instructional principles that underpin his work: breaking complex ideas into manageable steps, ensuring every student experiences success, and building confidence through carefully sequenced learning. The discussion explores the relationship between motivation and achievement, challenging the idea that some students are simply “maths people” while others are not. John argues that confidence is not a prerequisite for success but a consequence of it. Through examples from lessons on place value and long division, he demonstrates how micro-scaffolding, structured inquiry, and deliberate practice can help students tackle sophisticated mathematical ideas while remaining engaged and optimistic. Throughout the episode, Rebecca, Nathaniel and John discuss the role of challenge, the importance of maintaining students in an optimal learning zone, micro-scaffolding, and how effective teachers create classrooms where every learner can participate in meaningful thinking. The conversation extends beyond mathematics into broader questions about motivation, differentiation, classroom culture and what it means to teach with both precision and humanity. Mentioned resources and explainers John Mighton John Mighton is a mathematician, playwright and educator best known as the founder of JUMP Math. His work focuses on making mathematics accessible to all students through carefully sequenced instruction, micro-scaffolding and high expectations. His books can be found here, here and here. JUMP Math JUMP Math is an instructional approach and curriculum developed by John Mighton. The model emphasises breaking learning into small achievable steps while maintaining conceptual understanding and challenge. The 85% Rule A principle discussed by John suggesting that learners are most motivated when they are successful most of the time, but still experience enough challenge to stretch their thinking. The goal is to avoid both frustration and boredom. Structured Inquiry Rather than choosing between explicit instruction and discovery learning, structured inquiry carefully guides students towards important insights through well-designed questions, examples and prompts. Micro-Scaffolding A teaching approach that breaks complex concepts into very small, manageable components so that students experience repeated success while building towards sophisticated understanding. Collective Confidence John discusses how confidence can become a collective classroom phenomenon. When students repeatedly experience success and see their peers succeeding, expectations about who can learn begin to change. Deliberate Practice The idea that expertise develops through carefully designed practice targeting specific areas for improvement. John discusses how this principle influenced his thinking about mathematics instruction. The End of Ignorance John Mighton’s book exploring mathematics learning, intelligence, and the belief that far more students can succeed in mathematics than is commonly assumed.
