Class divided: How Aussie highschoolers are separated on ability

New research from Edith Cowan University (ECU) has unveiled how Australian secondary schools make decisions about organising students into classes based on their perceived academic ability

2025-07-29
(Press-News.org) New research from Edith Cowan University (ECU) has unveiled how Australian secondary schools make decisions about organising students into classes based on their perceived academic ability.

Lead author Dr Olivia Johnston explained that the findings show class ability grouping is often used despite evidence suggesting the practice be delayed and minimised.

“We need to support schools’ informed decision making about class ability grouping. Schools are busy places and there’s a lot of competing pressures. Forming class groups is one decision they make in a myriad of decisions, but it can have far reaching academic and social impacts for students,” Dr Johnston said.

“We know that student abilities aren’t static and develop over time.

“Class grouping by ability does not improve overall student academic outcomes and there are equity concerns associated with the practice.

“If students are grouped into classes by ability, it is recommended that the groupings are as flexible as possible, and that academic achievement is used to inform placements."

Flexible and inclusive grouping practices enable schools to ensure that students are not ‘locked in’ to lower ability groups.

“Our study reveals that schools draw on a range of information to determine how to group classes from Year 7-9 by ability, including student effort, behaviour concerns, parent requests, friendships, teacher recommendations and academic achievement,” Dr Johnston explained.

The findings form part of a three-year research project led by ECU’s School of Education.

Data from the first year of the study included a survey that went to every secondary school in Western Australia and most Queensland secondary schools.

“Of the 147 participant secondary schools, we conducted 12 in-depth follow up interviews with school leaders to gain detailed insights into class grouping practices,” Dr Johnston said.

“We looked at how schools are making decisions about which classes students from Year 7–9 are put into. And if they are using ability grouping, how the school decides what a student’s ability group should be.”

What information are schools using to create class ability groups?

Where class ability grouping was used, most schools reported grouping students through a combination of achievement data from NAPLAN (76.1%), teacher recommendations (73.9%), primary and secondary school achievement data (59.8% each), and other standardised tests (52.2%).

“Schools that used mixed ability class groupings referred to teacher recommendations and past achievement data to ensure that students of all academic ability levels were spread across classes,” Dr Johnston explained.

Dr Johnston recommended that schools take care to ensure students are not inadvertently being sorted into groups according to their social backgrounds.

To group or not to group by ability

Of the 147 participant secondary schools, 92 confirmed using ability grouping in Year 7–9.

“Many of the schools that weren’t using class ability grouping either didn’t have big enough student numbers, as is the case for many remote or regional schools, or they follow an alternative school philosophy such as Montessori,” Dr Johnston said.

“Schools use a range of datapoints and often undergo extensive in-school consultation processes when making decisions on class groups – whether they group by ability or not. But they don’t follow any specific Australian guidelines or official framework when making these decisions, because there are none available.

“Secondary schools that have programs for academically gifted students can face the added burden of managing parents pushing for their child to get a place in extension classes.

“One school detailed how they’ve had to safeguard around pressure from parents by addressing it in advance to avoid being inundated with requests.”

Class grouping practices seldom significantly change

“The other interesting finding was that class grouping practices used by schools rarely significantly changed,” Dr Johnston said. “However, the research revealed that schools are interrogating their practice and are open to change if it means improving student educational outcomes.”

Of the schools surveyed, 71.3% reported that they had not changed their class grouping practices in three years and 88.7% plan to continue using the same practices.

“Schools, teachers, and future generations of school leaders have an incredible opportunity to prevent class grouping practices from reflecting preexisting social inequality among students.

“By using mixed ability class groups, we can further empower schools to differentiate their teaching practices while reducing the disadvantage and privilege divide.”

Polygenic architecture of dental caries: single nucleotide polymorphisms in genetic epidemiology

2025-07-29
Dental caries remains a significant global public health burden, affecting billions worldwide despite preventive measures. While behavioral and socioeconomic factors are primary drivers, individual susceptibility varies markedly among those with similar risk profiles. This review synthesizes evidence establishing a substantial genetic component in caries etiology, mediated through polygenic mechanisms and epistatic interactions across key biological pathways. Genetic Pathways and Key Findings 1. Tooth Mineralization Genes: Key Genes: AMBN, AMELX, ENAM, MMPs (e.g., MMP2, MMP20), KLK4, TFIP11, BMP7, *DLX3/DLX4*. Mechanism: Variants ...

Interrater reliability of the Nancy Histologic Index in assessing histologic remission in treated ulcerative colitis biopsies: a multi-institutional experience among gastrointestinal pathologists in t

2025-07-29
Background and objectives Histologic remission is recommended as an adjunctive treatment target in ulcerative colitis, and scoring systems have been proposed to enhance reproducibility. The Nancy Histologic Index (NHI) is increasingly used in clinical trials; however, its performance in real-world settings is not fully established. This study aimed to assess the interrater reliability (IRR) of the NHI among gastrointestinal pathologists in the United States. Methods Thirty-seven whole-slide images of colorectal biopsies from 34 treated ulcerative colitis patients enrolled in a multicenter adult cohort were independently ...

Physical inactivity crisis costing US $192 billion annually, new study reveals

2025-07-29
WASHINGTON, D.C. – A new study published in the American Journal of Health Promotion finds that inadequate leisure-time aerobic physical activity accounts for $192 billion in annual healthcare costs among U.S. adults—12.6% of total national health care spending. Researchers analyzed data from more than 76,000 adults between 2012 and 2019. The findings are stark: 52.4% of adults met aerobic activity guidelines   20.4% were insufficiently active   27.3% were completely inactive   The average adult incurred $6,566 in annual healthcare costs   Compared to active adults: Insufficiently active adults incurred $1,355 more than active adults in annual ...

Groundbreaking research to identify early signs of multiple sclerosis

2025-07-29
In a major step towards early detection, University of South Australia researchers are investigating the biology behind multiple sclerosis (MS) to help predict people’s genetic risk of developing the disease, long before any symptoms appear.   Funded by an MS Australia Incubator Grant announced today, the Australian-first study will use a powerful new research method known as ‘recall by genotype’ to explore genetic causes of MS.   Specifically, the study will explore links between MS and the Epstein-Barr virus – a common ...

Designing drones that can fly in air ducts

2025-07-29
Air ducts: a contemporary issue for safety inspection Air ducts are everywhere in modern buildings and underground networks, but are challenging to access for inspection. Their narrow dimensions and inability to support human weight prevent essential interventions to maintain air quality, heating, and air conditioning. Small quadrotor drones offer a potential solution for exploring these air ducts because they can navigate both horizontal and vertical sections. However, they create airflows that recirculate inside the duct and destabilize the drone, creating important turbulences in an environment that has little space for error. Mapping the aerodynamic forces in a ...

With no need for sleep or food, AI-built ‘scientists’ get the job done quickly

2025-07-29
Imagine you’re a molecular biologist wanting to launch a project seeking treatments for a newly emerging disease. You know you need the expertise of a virologist and an immunologist, plus a bioinformatics specialist to help analyze and generate insights from your data. But you lack the resources or connections to build a big multidisciplinary team.  Researchers at Chan Zuckerberg Biohub San Francisco and Stanford University now offer a novel solution to this dilemma: an AI-driven Virtual Lab through which a team of AI agents, each equipped with varied scientific expertise, can tackle sophisticated and open-ended scientific problems by formulating, refining, ...

Blood tests show potential for colorectal cancer detection, but follow-up still falls short

2025-07-29
FINDINGS A study led by investigators at the UCLA Health Jonsson Comprehensive Cancer Center found that while blood-based tests offer a more convenient option for colorectal cancer screening, only 49% of patients completed a follow-up colonoscopy within six months, and just 56% did so at any point during the two-year study period. Follow-up colonoscopy is a critical next step to confirm the presence of colorectal cancer or pre-cancer after an abnormal screening result. These follow-up rates are comparable to those observed with stool-based screening tests, but remain far below optimal levels needed for timely cancer detection and treatment. The team also found that individuals ...

A twangy timbre cuts through the noise

2025-07-29
WASHINGTON, July 29, 2025 — Twangy voices are a hallmark of country music and many regional accents. However, this speech type, often described as “brassy” and “bright,” can also be used to get a message across in a noisy environment. In JASA Express Letters, published on behalf of the Acoustical Society of America by AIP Publishing, researchers from Indiana University found that it was easier to understand twangy female voices compared to neutral voices when surrounded by noise. Found in accents in American cities such as Chicago, Boston, New York, ...

How does the immune system prepare for breastfeeding?

2025-07-29
LA JOLLA (July 29, 2025)—Of the 3.6 million babies born in the United States each year, around 80 percent begin breastfeeding in their first month of life. Breastfeeding has known benefits for both mother and child, reducing maternal risk of breast and ovarian cancers, type 2 diabetes, and high blood pressure, while simultaneously supporting the baby’s nutrition and immune system. But because pregnancy and lactation have been historically understudied, we still don’t understand the science behind many of these benefits. Salk Institute immunologists are changing that—starting with a map of ...

Trends in medical and nonmedical use of prescription stimulants among US adolescents

2025-07-29
About The Study: Among U.S. adolescents, current medical use of prescription stimulants for attention-deficit/hyperactivity disorder (ADHD) increased between 2005 and 2023, while nonmedical use decreased. Lifetime nonmedical use was more prevalent than medical use in early cohorts but shifted to being less prevalent in recent cohorts. These findings are consistent with declines in peer-to-peer diversion among adolescents following COVID-related school closures and findings from adult studies.  Corresponding ...
