"What is needed is a culture of success, backed by a belief that all can achieve. Formative assessment can be a powerful weapon here if it is communicated in the right way.”
"The formative assessment experiments produce typical effect sizes of between 0.4 and 0.7 : such effect sizes are larger than most of those found for educational interventions.
• A gain of effect size 0.4 would improve performances of pupils in GCSE by between one and two grades.
• A gain of effect size 0.7, if realised in the recent international comparative studies in mathematics (TIMSS—Beaton et al., 1996), would raise England from the middle of the 41 countries involved to being one of the top 5.

Q: Does Working Memory Training lead to improvements outside of the training? A: Not very usefully. They say: “First, training in low WM children leads to generalized enhancements to a wide range of untrained WM tasks. Second, these gains do not translate into capacity improvements on ecologically valid measures of WM or to gains in academic progress”

"Since the spacing effect was first discovered by Ebbinghaus in 1885, research has consistently shown that learning performance improves if multiple study sessions are separated in time (or “spaced”) rather than massed together.” (page 29-30)
They summarise that the “strength of evidence for educational effectiveness” of retrieval practice is high. (Page 10)
A Review of Educational Interventions and Approaches Informed by Neuroscience
EEF 2018
The evidence indicates a large dip in mathematical attainment as children move from primary to secondary school in England, which is accompanied by a dip in learner attitudes. There is very little evidence concerning the effectiveness of particular interventions that specifically address these dips. However, research does indicate that initiatives focused on developing shared understandings of curriculum, teaching and learning are important. Both primary and secondary teachers are likely to be more effective if they are familiar with the mathematics curriculum and teaching methods outside of their age phase. Secondary teachers need to revisit key aspects of the primary mathematics curriculum, but in ways that are engaging and relevant and not simply repetitive. Teachers’ beliefs about their ability to teach appear to be particularly crucial for lower-attaining students in Key Stage 3 mathematics … Evidence indicates a significant dip in mathematical attainment at transition. For example, in a large national study of primary attainment in England, Brown et al. (2008) found that, at the end of Year 7, a full year after the transition to secondary school, learners’ performance on a test of primary numeracy was below their performance at the end of Year 6 (page 163)
“there is no research evidence concerning the effectiveness of specific interventions in this area … Although some of the studies were conducted some time ago, there is no reason to suppose that the current situation is any different”(page 164)

EEF 2021a
Retrieval practice
The findings in this area are mostly positive, suggesting moderate effect sizes, but there were an appreciable number of neutral or negative results. (page 78)
“The overall evidence is therefore positive for retrieval practice. One area of concern in the main results was the low ecological validity of the studies in the review: many interventions were wholly scripted with a standardised procedure.” (page 92)
Cognitive Science in the classroom - Evidence and practice review
… but are the benefits of spacing and retrieval practice additive?
“For example, many teachers and practice review sources firmly linked retrieval practice and spaced practice. Both are forms of desirable difficulty for which the effects may not be entirely additive, as explained in a point by Putnam and Roediger:
‘Combining retrieval practice with spacing creates an interesting situation, however, because retrieval practice is more effective when it is successful, but increasing the gaps between retrieval practice opportunities makes retrieval more difficult (less successful). Thus, the positive effects of spacing and retrieval practice may be working against one another, at least when no feedback is provided on the test.’ (Putnam and Roediger, 2018, p. 177) page 84.
However if one can get the timing right, and timely practice usually can, one can increase the spacing between retrieval practices and ensure the learner is successful (because the timing is personalised, so one can gradually increase the durability of recall-ability) we should see the benefits of retrieval practice and spacing.
EEF 2021b
Research on teaching using worked examples
“suggests a small to moderate positive effect of using worked examples for secondary-age students in maths and science, compared to conventional problem-solving techniques” (page 104)

Teaching using scaffolding
Overall, evidence suggests that well-targeted scaffolds, guidance, or schema-based supports are an effective approach to support students to solve problems or learn from complex tasks in Key Stage 2 to Key Stage 4 (age 8 to 16) in a range of subjects. (page 111)
Cognitive Science in the classroom - Evidence and practice review
EEF 2021d
Managing cognitive load
Overall, the evidence is promising and indicates the value and importance of teachers seeking to optimise learners’ cognitive load. There are numerous studies showing appreciable positive effects for strategies to manage cognitive load within the evidence we have. There are also appreciable numbers of neutral and negative results, suggesting complexity in the principles and challenges of making it work in practice. (page 118)
and
Our confidence is in the value of optimising cognitive load rather than a specific strategy for doing so, or for specific learner needs.’ The main results also suggested great complexity and practical challenges for optimising cognitive load in practice. (page 134)

Within-class attainment grouping
Since Danielle Mason 2018 EEF Blog: Grouping pupils by attainment, what does the evidence say?
“Within-class attainment grouping’ shows a positive average attainment impact, equivalent to around +3 months of additional progress.”
The impact has been downgraded to + 2 months
EEF 2023
The attainment gap grows as learners progress through the education system, meaning that it is at its widest when learners reach the post-16 stage. Failing to achieve a standard pass in GCSE Maths or English has significant impacts on learners’ lives:
• Learners with 5 or more GCSEs, including English and Maths, as their highest qualification are estimated to earn £100,000 more in their lifetime than those with below level 2 or no qualifications.

Gathercole 2008
“The majority of children with poor working memory are slow to learn in the areas of reading, maths and science, across both primary and secondary school years”.
Learners with smaller working memories experience a double whammy of disadvantage
they are less likely to build chunks in long-term memory after the lesson than their peers,
they are more dependent on chunks in long-term memory to process the content of lessons than their peers.
Learning difficulties arise because they
“are unable to meet the memory demands of many structured learning activities” and “as a consequence, their working memory becomes overloaded ... information that is needed to guide the ongoing learning activity ... is lost”.
Gobet 2005
“Use an ‘improving spiral’, where you come back to the same concepts and ideas and add increasingly more complex new information”
Deliberate practice of similar but different problems assists the learner in building chunks in long term memory, which enables learning to be retained. Chunks also provide perceptual cues or triggers, so that the expert (or in our case the low attaining learner) can quickly and easily decide which chunk or chunks are likely to be useful to help solve a given problem.

Gobet 2012
A clear prediction of chunk-based theories is that individual differences play a large role in the early stages of learning
A clear prediction of chunk-based theories is that individual differences play a large role in the early stages of learning, as is typical of classroom instruction, but tend to be less important after large amounts of knowledge have been acquired through practice and study.
Chunk-based models actually warn us against any excess of optimism in the use of new technologies, as long as they do not help circumvent the key limiting constants of human cognition (i.e. attention, STM = working memory , and learning rates).

Goddard 2020a
Comparing 2 years maths teaching from the 4 lowest attaining sets, we find the timely practice class increases the median GCSE score from year 9 to year 11, more than the 3 business as usual classes (2 of which were previously more highly attaining).
Goddard 2020b
Guidance on the most worthwhile activities during lockdown:
Factoring in retrieval practice to remote education activities will help [the teacher] to maintain firm foundations for when learning hopefully continues back in school in September. This must be our priority: extending the durability of current learning, with the icing on the cake being new learning.
Much retrieval practice in schools is still inadvertent. End-of-unit and end-of-term tests are high-stakes, summative assessments. These can and should be missed out during school closure. Instead we should use well-timed retrieval practice to embed learning. For low, middle and high-attaining learners the suggested wait between teaching and first practice is 1 to 3 days, 7 to 10 days and 14 days respectively

For what we consider higher order skills, such as generalising and problem solving, research suggests, Mayfield & Chase (2002), that when students are using two different pieces of knowledge/skills/methods to learn a third, the students are most successful if both the two existing pieces of knowledge/skills/methods are more strongly embedded before the third is learned.

Executive Function difficulties and smaller Working Memory Capacity are among a number of learning difficulties that looked after children seem to experience.
Pan and Sana 2021
investigated the relative efficacy of pre testing (i.e., errorful generation) and post testing (i.e., retrieval practice).
Pre testing involves taking tests before to-be-learned information is studied,
whereas post testing involves taking tests after information is studied.
The key phrase used to describe this is test potentiated learning.
The experiments are all based on learning from reading a passage of text - so may not be as applicable to maths learning. If one only allows one test, then pretesting seems to be more effective than posttesting.
Of course if one wants to extend recall beyond the 48 hour delay and and one allows several retrieval practice questions, then retrieval practice with feedback can be expected to be more effective. Nonetheless pretesting, can be a valuable tool.
Pashler 2007
Giving feedback when the learner can’t retrieve (recall the learning) makes retrieval practice more effective. Feedback after a nights sleep is more effective than immediate feedback.

When learners see a list of problems, all of the same kind, they know the strategy to use before they even read the problem [that's] like riding a bike with training wheels.

Improving executive function is the key to improving working memory. WM training may have some positive effect, but so does physical activity, fantastical play! They say “Both direct training on WM tasks and practicing certain skills that may indirectly impact on WM (physical activity, fantastical play and inhibition) were beneficial. The common ingredient across effective interventions was the executive-loaded nature of the trained task i.e., training on a task that taps into attentional and processing resources under executive control not just the storage of information.” but “The strength of the evidence is tempered by a lack of clear theoretical underpinnings, rigorous methodology and consideration of dosage.”

“Schema construction has two functions: the storage and organization of information in long- term memory and a reduction of working memory load.”
People have very limited working memory capacities so attempting reasoning in working memory is inefficient and often error prone. Whereas prior problem solving, which helps us create schema (a.k.a. chunks) helps us to automate future problem solving. it is assumed this is because this gives us more working capacity for the unfamiliar parts of a problem. Even a very complex schema can be used by working memory as a single element. Building and using an increasing number of ever more complex schemas, by
“combining elements of lower level schemas in long term memory”
allows skilled performance to develop.
When teachers teach the “right grain size” attainment is raised (summary of van Merrienboer 1997)

When practice problems are blocked, however, learners can successfully solve a set of practice problems without learning how to pair a problem with the skill. Indeed, because all of the problems relate to the topic—typically the one presented in the immediately preceding lesson—learners can choose the appropriate procedure for each practice problem before they read the problem. While this reduces the difficulty of the practice problems, learners are effectively relying on a crutch.
