A 2025 peer-reviewed University of Sydney / University of Wollongong study (Zunica, Reid O'Connor & Cartwright, published in the Australian Educational Researcher) finds private tutoring is now mainstream for at least one in seven Australian students, with an estimated 80,000 private tutors working in Australia in 2024, but the sector lacks regulation, accreditation, or child-safety screening standards.

revealed that tutoring is now mainstream for at least one in seven Australian students, but lacks effective regulations to ensure safety, quality, or fairness. "Tutoring has grown to become a billion-dollar industry in Australia, but it lacks accreditation, enforced codes of conduct, or real protection for students," said Dr Zunica... Tutoring has also grown steadily in Australia in response to increased competition among students, with as many as 80,000 private tutors working in 2024, many without formal teaching credentials.

Mark Bray's foundational 'shadow education' definition: private supplementary tutoring in academic subjects, provided for a fee outside standard school hours, which 'mimics the mainstream' -- as the mainstream curriculum changes or expands, so does the shadow.

Although the term shadow education is used widely, it is not always employed with consistent meaning. It is therefore necessary at the outset to identify the parameters of the present study. It is concerned with tutoring in academic subjects that is provided for a fee and that takes place outside standard school hours... The study uses the metaphor of the shadow because much private supplementary tutoring mimics the mainstream... Thus, as the curriculum of the mainstream changes, so does the curriculum in the shadow. And as the mainstream expands, so does the shadow.

Evidence for Learning (the Australian mirror/localisation of the EEF Toolkit) confirms one-to-one tuition delivers ~5 months' additional progress on average, but notes there is little Australian-specific research isolating the one-to-one element's effectiveness, with primary-school gains (+6 months) exceeding secondary (+4 months), and literacy gains (+6 months) exceeding maths (+2 months).

Despite the popularity and success of one to one programs, there is little research that specifically examines the effectiveness of the one to one element of these programs in Australia.

A 2022 EduResearch Matters/AARE blog critique argues AERO's NAPLAN writing-decline report ('Writing development: What does a decade of NAPLAN data reveal?') should be disregarded because it presents no estimates of sampling error, despite roughly 10% of the population not sitting the NAPLAN writing exam (introducing known non-random sampling error), a standard practice ACARA itself follows in its own NAPLAN technical reports.

There are two lines of technical concern which need to be noted. These concerns reveal reasons why this report should be disregarded – and why media response is a beatup... The fact these are estimates is not apparent in the current report. There is NO presentation of any of the estimates of error in the data used in this report...

A July 2025 EduResearch Matters/AARE critique argues AERO's School Writing Instruction Framework (SWIF) is based on a narrow subset of evidence (applied linguistics/genre theory only), disregarding AERO's own prior 2022 acknowledgement that 'no single pedagogy adequately addresses all aspects' of writing, and ignoring recent meta-analyses of nearly 1,000 writing-instruction studies that recommend an integrative approach.

While there are a number of positives in this model and its accompanying practice resources, we argue here that these are based largely on a subset of evidence. It dismisses significant bodies of work with demonstrated impact on student writing achievement. Paradoxically, these were at the core of AERO's previous documentation... In its 2022 review of instructional approaches to writing AERO rightly claimed, “no single pedagogy adequately addresses all aspects of the knowledge, skills and strategies required for skilled writing”. The major pitfall of SWIF is its overwhelming focus on one of these approaches, applied linguistics. There is a total disregard for the most recent and compelling writing instruction recommendations based on meta-analyses of nearly one thousand studies in writing instruction.

A meta-analysis of the National Reading Panel's phonics database found systematic phonics instruction produces a moderate overall effect on reading (approximately d = 0.4-0.44 across 66 treatment-control comparisons from 38 experiments), with substantially larger effects when phonics instruction begins early (Kindergarten/Year 1, d = 0.55) than when it begins after Year 1 (d = 0.27).

There were 38 studies from which 66 treatment-control group comparisons were derived. ... The mean overall effect size produced by phonics instruction was moderate in size and statistically greater than zero, d = 0.44. ... [Effect sizes for beginning phonics instruction in kindergarten or 1st grade were] significantly larger (d = 0.55) than effect sizes above 1st grade (d = 0.27). These results support Chall's (1967) assertion that early instruction in systematic phonics is especially beneficial to growth in reading.

In the classic 'baseball study', prior topic knowledge had a stronger effect than general reading ability on Year 7-8 students' comprehension and recall of a text: weaker readers with high baseball knowledge performed as well as strong readers, and there was a significant main effect for prior knowledge on all recall measures with no interaction between prior knowledge and reading ability.

We investigated how prior knowledge influences the amount of short-term nonverbal and verbal memory and long-term retention in students of high and low ability in reading comprehension. Sixty-four junior high students were divided into four equal-sized groups on the basis of preassessed reading ability (high and low) and preassessed amount of existing prior knowledge about baseball (high and low). ... There was a significant main effect for prior knowledge on all measures. No interactions between prior knowledge and ability were found. These results delineate the powerful effect of prior knowledge.

Cunningham and Stanovich's research found enormous differences in independent reading volume translate into vocabulary/word-exposure gaps: the average child at the 90th percentile of reading volume reads almost 2 million words per year outside school — more than 200 times the ~8,000 words per year read by the child at the 10th percentile — meaning a full year of a low-volume reader's out-of-school reading equals about two days of a high-volume reader's.

The average child at the 90th percentile reads almost two million words per year outside of school, more than 200 times more words than the child at the 10th percentile, who reads just 8,000 words outside of school during a year. To put it another way, the entire year's out-of-school reading for the child at the 10th percentile amounts to just two days reading for the child at the 90th percentile!

Nagy and Anderson's classic corpus analysis estimated there are approximately 88,500 distinct word families in printed school English, and argued that direct vocabulary instruction alone could not plausibly account for the number of words children actually learn — implying most vocabulary growth must come through wide reading and context/morphology.

Concludes that there are about 88,500 words in printed school English and that even systematic direct vocabulary instruction could not account for a significant proportion of all the words children actually learn, nor cover more than a modest proportion of the words they will encounter in school reading materials.

In a controlled fMRI study, James & Engelhardt (2012) found that pre-literate 5-year-old children who physically printed letters by hand showed significantly greater activation in the left fusiform gyrus — a region linked to visual word recognition/reading — when later passively viewing those letters, compared to children in typing or tracing training conditions; the paper describes this as extending an earlier finding (James, 2010) that printing (vs. visual-practice-only) produced the same fusiform effect.

Our region-of-interest analysis clearly demonstrates that in a region known to be involved in reading and letter processing—the left fusiform gyrus...is recruited more after printing experience than experience in typing, tracing or simply perceiving letters (control stimuli).

Longcamp et al. (2008) found that adults who learned new graphic characters by handwriting them (vs. typing them) showed stronger and longer-lasting facilitation in visually recognizing the correct orientation of those characters, with fMRI showing handwriting-learned recognition activated brain regions associated with the execution, imagery, and observation of actions (left Broca's area, bilateral inferior parietal lobules) -- direct evidence that motor memory from handwriting contributes to visual letter/character recognition.

Fast and accurate visual recognition of single characters is crucial for efficient reading. We explored the possible contribution of writing memory to character recognition processes. We evaluated the ability of adults to discriminate new characters from their mirror images after being taught how to produce the characters either by traditional pen-and-paper writing or with a computer keyboard. After training, we found stronger and longer lasting (several weeks) facilitation in recognizing the orientation of characters that had been written by hand compared to those typed. Functional magnetic resonance imaging recordings indicated that the response mode during learning is associated with distinct pathways during recognition of graphic shapes. Greater activity related to handwriting learning and normal letter identification was observed in several brain regions known to be involved in the execution, imagery, and observation of actions, in particular, the left Broca's area and bilateral inferior parietal lobules.

UK evidence using an instrumental-variables design around a historical elite/non-elite secondary school assignment formula finds attending an elite school produced large gains in completed education, but the pattern of effects on later-life labour market outcomes was uneven by sex (positive income effects for women, none for men) and came with a significant fertility cost for women — i.e. the causal gains were not simply general achievement gains.

Using instrumental variables methods that exploit the school assignment formula, we find that elite school attendance had large impacts on completed education. For women, we find that elite school attendance generated positive effects on labor market outcomes and significant decreases in fertility; for men, we find no elite school impacts on any of these later-life outcomes.

Where this displacement of curriculum occurred, NAPLAN test preparation became the proxy curriculum and teaching writing was reduced to a dominant focus on the structure of the writing, the formula for producing the narrative or the persuasive form, with some commentary about maximising the score on writing through 'gaming' the criteria. In commenting on classroom preparation of students for NAPLAN writing, one respondent said "You're forensically taking out different things, and you can formulaically produce a response that maximises the result" (Member of the NAPLAN Review Practitioners' Reference Group)... "The richness of writing has been lost. 'Cookie cutter' writing is being produced" (Subject association).

The first regression-discontinuity study of NSW selective high schools (the oldest and largest selective system in Australia) finds that receiving an offer to attend a selective school has only scattered, mostly statistically insignificant effects on overall student achievement and participation in advanced coursework — while low-SES students who do get in appear to benefit more, yet remain underrepresented in the selective intake.

I find that receiving an offer to attend a selective school has only scattered and mostly insignificant impacts on overall student achievement and participation in advanced coursework. I do find suggestive evidence that selective schools benefit low socioeconomic status students, but that such students are typically underrepresented in selective schools, which has implications for Gifted and Talented education policy.

US SAT test-preparation research using propensity-score matching to correct for self-selection bias finds coaching produces modest score gains (roughly 11-15 points on math and 6-9 points on verbal), and that gains are larger for higher-SES students who use private tutoring or commercial coaching than for lower-SES students using the same preparation types — evidence that coaching effects on ability-style admissions tests are real but modest, and unevenly distributed by family resources.

For those students that have taken both the PSAT and SAT, effect estimates of roughly 11 to 15 points on the math section and 6 to 9 points on the verbal are found. Only the math effects are statistically significant. ... When coached students in the top SES quartile are compared to uncoached students in the top SES quartile, we find a mean difference of 15 points on SAT math scores. In contrast, amongst students in lower SES quartiles, coaching has only a 5 point effect. ... On the verbal section... the effect is 9 points for high SES students but just 2 points for lower SES students.

A meta-analysis of 37 vocabulary intervention studies (Pre-K to Grade 12) found vocabulary instruction produces a moderate-to-large effect on comprehension measures custom-built to match the taught words, but a much smaller effect on standardized comprehension tests.

A meta-analysis of vocabulary interventions in grades pre-K to 12 was conducted with 37 studies to better understand the impact of vocabulary on comprehension. Vocabulary instruction was found to be effective at increasing students' ability to comprehend text with custom measures (d = 0.50), but was less effective for standardized measures (d = 0.10). When considering only custom measures, and controlling for method variables, students with reading difficulties (d = 1.23) benefited more than three times as much as students without reading problems (d = 0.39) on comprehension measures. Gains on vocabulary measures, however, were comparable across reading ability. In addition, the correlation of vocabulary and comprehension effects from studies reporting both outcomes was modest (r = 0.43).

A systematic review of 36 vocabulary-intervention studies found that directly teaching word meanings reliably improves comprehension of passages containing those specific taught words, but there is only weak evidence that vocabulary instruction improves generalized (untrained) reading comprehension.

Teaching of word meanings supported comprehension of text containing the target words in almost all cases... Direct vocabulary instruction showed "very limited evidence" for improving generalized reading comprehension, even with extensive, long-term interventions... instruction that focused on some active processing was typically more impactful than a definition or a dictionary method.

A peer-reviewed rebuttal (Golinkoff et al. 2019) argues the Sperry et al. replication critique should not be read as debunking the word gap, because it measures overheard speech rather than child-directed speech, and because their sample lacked a high-income comparison group; the rebuttal maintains that quality, child-directed language exposure (not raw word count) is what predicts language outcomes, and that SES-linked language gaps remain real.

Sperry, Sperry, and Miller (2018) aim to debunk what is called the 30-million-word gap by claiming that children from lower income households hear more speech than Hart and Risley (1995) reported. We address why the 30-million-word gap should not be abandoned, and the importance of retaining focus on the vital ingredient to language learning—quality speech directed to children rather than overheard speech, the focus of Sperry et al.'s argument... There are serious risks to claims that low-income children, on average, hear sufficient, high-quality language relative to peers from higher income homes.

Home observations occurred when children were 18-30 months old, continuing until ages 32-48 months... poor Black Alabama families: 1,838 words/hour from primary caregivers... working-class families: 1,048-1,491 words/hour...

Beck, McKeown & Kucan's influential vocabulary-instruction framework divides words into three tiers for instructional purposes: Tier 1 (basic, everyday words needing little instruction), Tier 2 (high-utility, cross-disciplinary academic words that are the priority for direct teaching), and Tier 3 (rare, domain-specific technical words).

Bringing Words to Life is an excellent resource that provides research-based strategies for vocabulary development with children from the earliest grades through high school... Teachers are guided in selecting words for instruction, developing student-friendly explanations of new words, creating meaningful learning activities and getting students involved in thinking about, using, and noticing new words both within and outside the classroom. Tier 1 words are basic words used often in everyday conversation, e.g. go, play. Tier 2 words are complex words that are more likely to occur in academic settings, e.g. compare, neutral. Tier 3 words are highly specialised, subject-specific words, e.g. isosceles.

Vocabulary knowledge and reading comprehension develop reciprocally: children with better vocabulary show better comprehension, and their comprehension improves faster over time; written text is a richer source of new vocabulary than everyday spoken language because it contains less common vocabulary.

Good vocabulary knowledge is also related to growth in reading comprehension over time: children with better vocabulary have better reading comprehension, and their comprehension improves more over time... vocabulary is an unconstrained skill: we learn the meanings of new words throughout our lifetime, and an important source of new word learning is written text. This is because written texts are a much richer source of new words than spoken language; they have less common vocabulary than does everyday spoken language, so they afford more opportunities for learning new vocabulary.

According to the expertise reversal effect, the heavy use of worked examples becomes less and less effective as learners' expertise increases, eventually becoming redundant or even counter-productive to learning outcomes.

Cognitive load theory, evidenced primarily by randomised controlled trials in technical/STEM domains (mathematics, science, technology), supports explicit instruction with modelling, guided practice, and feedback as more effective and efficient than minimally-guided/discovery approaches for novice learners; the source document itself notes far less research has tested this in humanities/creative subjects such as literature.

Decades of research clearly demonstrate that for novices (comprising virtually all students), direct, explicit instruction is more effective and more efficient than partial guidance. So, when teaching new content and skills to novices, teachers are more effective when they provide explicit guidance accompanied by practice and feedback, not when they require students to discover many aspects of what they must learn.

A large-scale meta-analysis of the spacing/distributed-practice effect across verbal recall tasks found consistent benefits of spacing study sessions apart rather than massing them, based on hundreds of experiments, and showed that the optimal gap between study sessions increases as the desired retention interval increases.

The authors performed a meta-analysis of the distributed practice effect to illuminate the effects of temporal variables that have been neglected in previous reviews. This review found 839 assessments of distributed practice in 317 experiments located in 184 articles. Effects of spacing (consecutive massed presentations vs. spaced learning episodes) and lag (less spaced vs. more spaced learning episodes) were examined, as were expanding interstudy interval (ISI) effects. Analyses suggest that ISI and retention interval operate jointly to affect final-test retention; specifically, the ISI producing maximal retention increased as retention interval increased.

Across a meta-analysis spanning multiple performance domains, the amount of deliberate (structured, feedback-driven) practice a person has accumulated explains only a small proportion of variance in achievement within education specifically -- far less than in games, music, or sports -- indicating that practice quantity alone is not a sufficient explanation for educational attainment.

We found that deliberate practice explained 26% of the variance in performance for games, 21% for music, 18% for sports, 4% for education, and less than 1% for professions. We conclude that deliberate practice is important, but not as important as has been argued.

Interleaved practice (mixing different problem types within a practice session, rather than practicing one type in a block before moving to the next) produced markedly higher test scores than blocked practice for secondary-school mathematics students, with the advantage growing larger on a delayed test than an immediate one.

In the experiment reported here, 126 seventh-grade students received the same practice problems over a 3-month period, but the problems were arranged so that skills were learned by interleaved practice or by the usual blocked approach. The practice phase concluded with a review session, followed 1 or 30 days later by an unannounced test.

In a meta-analysis of true and quasi-experiments (grades 2-12), having students write about the texts they read (personal response, summaries, notes, or answering questions in writing) reliably improved their reading comprehension, with 93% of measured outcomes positive and an average effect size of 0.40 — larger (0.63) for lower-achieving students, provided they were explicitly taught how to do it.

The evidence shows that having students write about the material they read does enhance their reading abilities. In fact, fifty-seven out of sixty-one outcomes (93 percent) were positive, indicating a consistent and positive effect for writing about what is read. The impact of writing about reading applied broadly across different levels of schooling, as students participating in this research were in grades 2–12 [...] The effect size for writing about text that was read (0.40) exceeded each of these effects [reading programs at the secondary level, reciprocal teaching, and vocabulary instruction], providing additional validation of its effectiveness [...] In twelve studies involving [lower-achieving] students, the average weighted effect size for writing about a text was 0.63. However, the average weighted effect size for writing about text activities was not greater than zero when lower-achieving students were not explicitly taught how to use them.

In a nationally representative UK cohort followed from birth, adults who had been frequent readers in childhood still had noticeably higher vocabulary scores at age 42 (30 years later) than infrequent childhood readers, even after controlling for social background — and adults who read literary ('highbrow') fiction scored higher on the same test than adults who did not.

Researchers at the Institute of Education (IOE) have reached this conclusion after studying the vocabulary test scores of more than 9,400 British people at the ages of 10, 16 and 42. [...] even after these factors were taken into account there was still a 9 percentage point gap in vocabulary scores at age 42 between those who were either frequent or infrequent readers in their youth.

We examined reading experience and ToM in 236 children between the ages of 11–13 years. Participants were asked to report on their time spent reading both fiction and non-fiction at ages 11 and 13; ToM was measured at age 13. [...] Results showed that children's self-reported fiction, but not their non-fiction reading was associated with ToM. Further, the association was concurrent but not longitudinal: fiction reading and ToM at age 13 were associated but fiction reading at age 11 did not predict ToM at age 13.

A large, three-lab replication attempt found no significant advantage in theory-of-mind test scores from reading literary fiction compared to popular fiction, nonfiction, or no reading — directly contradicting Kidd & Castano (2013).

Here we report a replication attempt by 3 independent research groups, with 792 participants randomly assigned to 1 of 4 conditions (literary fiction, popular fiction, nonfiction, and no reading). In contrast to Kidd and Castano (2013), we found no significant advantage in RMET scores for literary fiction compared to any of the other conditions.

Across correlational studies, people's habitual (leisure) fiction reading is weakly-to-modestly associated with better theory-of-mind/social-cognition scores, with a similar small correlation for narrative immersion and a smaller one for self-reported empathy.

reading fiction predicts self-reported empathy (r = 0.07), fantasy (i.e., the degree to which a reader becomes immersed in stories; r = 0.18), and performance on theory-of-mind tasks (r = 0.21)

Across OECD countries, 15-year-olds who read books more often in paper format scored 49 points higher on the PISA 2018 reading test than students who rarely or never read books, after accounting for socio-economic profile and gender (vs. a 15-point advantage for those who read mainly on digital devices).

Compared with students who rarely or never read books, students who read books more often in paper format scored 49 points higher in the PISA 2018 reading test after accounting for students' and schools' socio-economic profile and students' gender. A corresponding performance advantage for students who read books more often on digital devices is 15 points.

A large 2022-2023 survey of Australian secondary school students (~12,000-13,000, years 7-12, across NSW, VIC, QLD, WA) found 54% read more than once a week and fiction is the most popular genre and print the preferred format, but 29% of students reported not engaging with reading at all in their free time.

The report shows that 54% of teens read upwards of once a week – with fiction being the most popular genre, and print books being preferenced over other formats. The survey data also shows a significant portion of Australian teens are missing out on access to the benefits of reading for pleasure, with 29% of school students not engaging with reading in their free time.

In a large annual UK survey (70,403 children and young people aged 5-18 in early 2022), fewer than half (47.8%) of 8-18 year olds said they enjoyed reading — matching the previous 15-year low recorded in 2020 — with a widening gap between children eligible for free school meals and their peers.

Fewer than 1 in 2 (47.8%) children aged 8 to 18 said they enjoyed reading in 2022. [...] reading enjoyment 'reached a 15-year-low in early 2020' but temporarily increased during the first lockdown in spring 2020. However, any gains made during the early part of the pandemic had completely eroded by 2022.

In a set of five lab experiments, adults who read excerpts of literary fiction scored higher immediately afterward on a theory-of-mind (mind-reading) test than adults who read popular fiction, nonfiction, or nothing.

We present five experiments showing that reading literary fiction led to better performance on tests of affective ToM (experiments 1 to 5) and cognitive ToM (experiments 4 and 5) compared with reading nonfiction (experiments 1), popular fiction (experiments 2 to 5), or nothing at all (experiments 2 and 5). Specifically, these results show that reading literary fiction temporarily enhances ToM.
