When a skill or piece of knowledge is automatic, it can be executed with minimal cognitive load. The response comes without deliberate thought (Ericsson & Kintsch, 1995). **Example**: A student who has automaticity in multiplication facts can answer $7 \times 9 = 63$ quickly and with minimal effort, freeing their mind for other tasks. ### Fluency **Fluency** describes a level of mastery where a skill is automatic and can be applied flexibly and efficiently across varied contexts (National Mathematics Advisory Panel, 2008). **Example**: A student who is fluent in multiplication facts can answer $7 \times 9 = 63$ with automaticity and can use a variety of mental strategies such as doubling and halving, the distributive law, and factorising to check their answer or solve other problems. They select strategies strategically based on the context (Star & Rittle-Johnson, 2008). Automaticity enables speed; fluency enables adaptation. ## Practical example: finding 25% of 300 The answer, 75, likely came to mind instantly without conscious effort. This is because you immediately recognised the percentage sign, knew that 25% is equivalent to a quarter, and had automated the procedure for finding a quarter. This knowledge does not occupy any space in your [[Memory|working memory]] (Cowan, 2001). Without straining your working memory, you halved 300 twice, or found a quarter of 100 and multiplied by 3. You probably used more than one method to check your answer. This fluency allows you to perform the calculation even with distractions, such as background music or conversations (Logan, 1988). Fluency frees up working memory for other tasks. ## Expert versus novice performance A novice can also find 25% of 300, but it requires more cognitive effort. They might not instantly interpret the question, might not know that 25% is the same as a quarter, and may start by finding 10%, then 5%, and adding these together. Both experts and novices can get the answer right, but it is less cognitively demanding for the expert (Chi, Feltovich, & Glaser, 1981; Sweller, 1988). The differences extend across multiple dimensions of performance. Novices expend high cognitive effort, requiring conscious attention for each step, whilst experts operate with minimal working memory load. Strategy recognition differs. Novices may not recognise that 25% equals one quarter, whilst experts identify patterns instantly. Method selection shows similar disparities: novices typically rely on a single approach, whilst experts maintain multiple strategies and select flexibly between them. Verification approaches differ. Novices may not check their work or simply repeat the same method, whilst experts use different methods to verify answers. Under pressure or distraction, novice performance degrades substantially, whilst experts maintain accuracy despite competing demands on attention. ## Fluency in problem-solving ![[ProblemSolving.png]] Some problems are cognitively demanding for both experts and novices. However, experts have automated the basic knowledge involved (Ericsson & Kintsch, 1995). They do not need to think about what each term in the formula means, how to square 5, how to find a third, or what to do with the pi symbol. This frees up cognitive capacity to focus on the global features of the problem, such as interpreting the question correctly and devising a strategy for solving it (Chi, Feltovich, & Glaser, 1981). Experts are more likely to solve the problem and [[Expertise Reversal Effect|learn]] from the experience (Sweller, van Merriënboer, & Paas, 2019). Novices may get bogged down in the [[Surface and Deep Structure|minutiae]] of the problem, experience [[Cognitive Load Theory|cognitive overload]], and learn nothing transferable (Sweller, 1988). ## Development process Skill development progresses through overlapping phases. Building automaticity begins with understanding concepts and procedures through explicit instruction (Rosenshine, 2012). Extensive repetition builds speed and accuracy (Ericsson, Krampe, & Tesch-Römer, 1993), with continued practice until responses become automatic (Logan, 1988). Achieving fluency extends beyond automaticity. Students must learn multiple approaches to the same problems (Star & Rittle-Johnson, 2008) and practise applying skills in varied contexts (National Mathematics Advisory Panel, 2008). Fluency develops when students link procedures to underlying principles (Rittle-Johnson, Siegler, & Alibali, 2001) and learn to choose the most appropriate strategy for specific situations (Siegler, 1996). ## Indicators of fluency Fluency has three interconnected dimensions. Speed and accuracy include rapid, correct responses without hesitation, consistent performance across problem variations, maintained accuracy under time pressure, and minimal errors on routine calculations. Flexibility appears when students have multiple solution strategies available, can switch between methods as appropriate, adapt their approach based on problem characteristics, and use efficient methods for specific contexts. Understanding shows when students can explain why procedures work, connect procedures to underlying concepts, recognise when methods apply or do not apply, and use knowledge to verify the reasonableness of answers. ## Building fluency in practice Systematic development follows a progression across four stages. Understanding establishes the conceptual foundation through worked examples and explanations. Assessment checks whether students can explain the procedure. Accuracy focuses on correct execution through guided practice and feedback, with assessment examining high accuracy on untimed work. Speed develops efficient performance through timed practice and drilling, with assessment confirming quick responses whilst accuracy is maintained. Flexibility addresses strategy selection through exposure to multiple methods and problem variety, with assessment examining whether students choose appropriate strategies. Effective instruction follows several principles. Sufficient practice requires extensive repetition beyond initial success to achieve automaticity (Ericsson & Kintsch, 1995). Distributed practice uses spaced review to maintain fluency over time (Cepeda et al., 2006). Progressive complexity increases challenge as fluency develops (van Merriënboer et al., 2003). Multiple contexts provide practice in varied situations to build flexible application (National Mathematics Advisory Panel, 2008). ## Common misconceptions about fluency The 'understanding versus memorisation' dichotomy presents a false choice. Fluency requires both understanding and automaticity working together (Rittle-Johnson, Siegler, & Alibali, 2001). Automated knowledge frees working memory for complex thinking (Cowan, 2001), enables pattern recognition and strategic thinking (Chase & Simon, 1973), supports problem-solving in novel contexts (Chi, Feltovich, & Glaser, 1981), and reduces cognitive load during learning (Sweller, van Merriënboer, & Paas, 2019). 'Drill and kill' concerns arise from poorly designed practice rather than from repetition itself. Quality practice is based on solid conceptual understanding (Rittle-Johnson, Siegler, & Alibali, 2001), uses varied and engaging formats, maintains appropriate challenge levels (van Merriënboer et al., 2003), and includes clear purpose and progress monitoring. ## References Cepeda, N.
