Trends in Neuroscience and Education最新文献

Individuals use diverse strategies to solve mathematical problems, which can reflect their knowledge of arithmetic principles and predict mathematical expertise. For example, ‘6 + 38 − 35’ can be solved via ‘38 − 35 = 3’ and then ‘3 + 6 = 9’, which is a shortcut-strategy derived from the associativity principle. The shortcut may be critical for understanding algebra, however approximately 50% of adults fail to use it. We review the research to consider why the associativity principle is challenging and highlight an important distinction between shortcut identification and execution. We also discuss how domain-specific skills and domain-general skills might play an important role in shortcut identification and execution, and provide an agenda for future research.

BACKGROUND

Studies of children and adolescents suggest that reasoning training may improve both reasoning and academic achievement, but evidence and systematic evaluation of this research is limited. Accordingly, this paper provides a systematic review of the literature on reasoning training in order to describe current methods and evaluate their efficacy.

METHOD

A systematic search identified eleven articles—published between 1996 and 2016—that reported findings from thirteen separate studies of reasoning training effects on fluid reasoning (Gf) and academic achievement in children and adolescents. Specific Gf outcomes examined were analogical, deductive, inductive, nonverbal, and/or relational reasoning ability. Specific academic achievement outcomes examined were math and reading achievement. This paper reviewed studies utilizing both computerized and non-computerized methods of Gf training.

FINDINGS

Findings from the review show that reasoning training improves Gf (near transfer effects). Although less conclusive, when considered on balance, evidence suggests that reasoning training also improves academic achievement (far transfer effects).

CONCLUSIONS

Research is needed to parameterize the effects of Gf training on academic achievement, and in particular to identify moderators of training efficacy on academic outcomes. Limitations and directions for future research are discussed.

Background

Providing physical activity during the school day may mitigate increasingly sedentary lifestyles among children. Young children may be susceptible to interference during learning and consolidation when performing physical activity concurrently with academic instruction.

Methods

Preschoolers (N = 72, mean age 5.1 ± 0.8 years, 50% female) completed a quantity estimation task before, following, and one week after engaging in either a 20-min physically active or sedentary lesson. Physical activity intensity and volume were measured using heart rate and pedometer step counts, respectively. Off-task behavior was recorded prior to and following the lesson.

Results

Children exhibited similar learning and retention, but an added benefit of physically active lessons was a 1900% step increase and a 58% reduction in off-task behavior.

Conclusion

Providing physically active lessons instead of sitting for extended periods of time in early childhood classrooms reduces sedentary behavior and improves self-regulation while not interfering with educational outcomes.

Background

Block play is one type of intervention that improves visuospatial skills. There are multiple forms of block play and it is unclear whether they have differential cognitive effects.

Method

Given the importance of visuospatial skills for mathematical performance, we studied the differential impact of two types of block playstructured (copying a block design) and free (building from imagination) on arithmetic processing, using behavioral and fMRI methods. Forty-three children aged 8.3±0.8 years participated (21 free play and 22 structured block play).

Results

Results showed that while both groups showed behavioral improvements, only the structured block play group showed significant improvements in both addition and subtraction performance. Additionally, the structured block play group showed increased activation in several regions linked to memory, motor, and arithmetic processing after training.

Conclusion

The results inform choices for activities used in the classroom to improve visuospatial skills and suggest structured block play may be beneficial for arithmetic processing.

This review weighs the risk of infection with SARS-CoV-2 against the side effects of school closures on physical and mental health, education, and well-being of those affected by the school closures. Whereas short term effects – decreased learning and food security, and increased anxiety, violence against children, child labor and teen pregnancies – are frequently discussed, the long-term effects of school closures will be much more detrimental across the lifespan of the “Generation Corona”: Existing pandemics of inactivity and myopia, already affecting billions of people, are worsening due to less physical exercise and less time spent outdoors, poor diet, weight gain, and increased screen time during lockdowns, causing future increases of stroke, heart attack, cancer, and blindness. Socio-emotional complications of isolation, learned helplessness, economic and existential insecurity will include increased depression and suicide, decreased empathy and increased loneliness. Together with decreased educational attainment and economic productivity, the amount of ensuing increased future global morbidity and mortality justifies immediate action of school reopening.

Background

Prior studies reported that practice playing an approximate arithmetic game improved symbolic math performance relative to active control groups in adults and preschool children (e.g. Park & Brannon, 2013, 2014; Park et al., 2016; Szkudlarek & Brannon, 2018). However, Szkudlarek, Park and Brannon (2021) recently failed to replicate those findings in adults. Here we test whether approximate arithmetic training yields benefits in elementary school children who have intermediate knowledge of arithmetic.

Method

We conducted a randomized controlled trial with a pre and post-test design to compare the effects of approximate arithmetic training and visuo-spatial working memory training on standardized math performance in third and fourth grade children.

Results

We found that approximate arithmetic training did not yield any significant gains on standardized measures of symbolic math performance.

Conclusion

A Bayesian analysis supports the conclusion that approximate arithmetic provides no benefits for symbolic math performance.

Background

Owing to the prevalence of neuromyths in education, there has been a call for more teacher training in neuroscience. However, neuroscience is rarely featured in teacher education. This study investigated the neuroscience literacy and perceptions of neuroscience in education among preservice teachers in order to inform future development of initial teacher education.

Method

Neuroscience literacy of 968 preservice teachers and their perceptions towards applying neuroscience in education were examined using survey items adapted from studies addressing similar constructs. Rasch item response theory and classical test theory techniques were employed for data analysis.

Results

Most of the preservice teachers had limited brain knowledge and subscribed to many common neuromyths but were positive towards applying neuroscience in education. General brain knowledge was the only predictor for ability to identify neuromyths (β = .564).

Conclusion

Neuroscience knowledge can help safeguard preservice teachers against neuromyths. Neuroscience training deserves a place in teacher education.

Background

Graph analysis detects psychosis and literacy acquisition. Bronze Age literature has been proposed to contain childish or psychotic features, which would only have matured during the Axial Age (∼800-200 BC), a putative boundary for contemporary mentality.

Method

Graph analysis of literary texts spanning ∼4,500 years shows remarkable asymptotic changes over time.

Results

While lexical diversity, long-range recurrence and graph length increase away from randomness, short-range recurrence declines towards random levels. Bronze Age texts are structurally similar to oral reports from literate typical children and literate psychotic adults, but distinct from poetry, and from narratives by preliterate preschoolers or Amerindians. Text structure reconstitutes the “arrow-of-time”, converging to educated adult levels at the Axial Age onset.

Conclusion

The educational pathways of oral and literate traditions are structurally divergent, with a decreasing range of recurrence in the former, and an increasing range of recurrence in the latter. Education is seemingly the driving force underlying discourse maturation.

Background

It is not well understood whether qualified teachers believe neuromyths, and whether this affects their practice and learner outcomes.

Method

A standardised survey was administered to practising teachers (N = 228) to determine whether or not they believe fictional (neuromyth) or factual statements about the brain, the confidence in those beliefs, and their application.

Results

Although factual knowledge was high, seven neuromyths were believed by >50% of the sample. Participants who endorsed neuromyths were generally more confident in their answers than those who identified the myths. Key neuromyths appear to be incorporated into classrooms.

Conclusion

Australian teachers, like their overseas counterparts, have some neuroscience awareness but are susceptible to neuromyths. A stronger partnership with neuroscientists would addresss the complex problem of disentangling brain facts from fictions, and provide better support for teachers. This study uncovered psychometric weaknesses in the commonly used neuromyth measure that future research should address.
