  • Brock experts call for more tech education as provinces eye cellphone, social media bans in schools

    EXPERT ADVISORY — APRIL 30, 2026 — R0036

    Ontario’s push towards a ban on cellphones and social media in schools may be gaining momentum, but Brock University experts warn that without a clear plan, the move could leave students unprepared for the digital world beyond the classroom. 

    The province announced Tuesday it is considering stronger restrictions on technology in schools, but Mohammed Estaiteyeh says the policy might fall short of what students actually need. 

    The Brock Assistant Professor of Digital Pedagogies and Technology Literacies says bans alone are not a “fix” and must be paired with a clear educational strategy to be effective. 

    “Any restrictions in schools should be reinforced with ongoing teaching on digital literacy, digital citizenship, online safety and artificial intelligence (AI) literacy,” he says.  

    Otherwise, devices are being removed without teaching students how to handle them after school hours.  

    “Prohibition without education is a deferral, not a solution,” he says.  

    Estaiteyeh says a ban could widen inequities and increase the “digital divide.” 

    “Under-resourced schools rely on students’ personal devices for educational purposes because the school itself cannot provide them,” he says. “Furthermore, for students in underserved communities, a phone is often their primary computing device, their connection to family during long commutes and, in some cases, their accessibility tool.” 

    If not all schools in Ontario have equitable access to classroom technology to facilitate technology-enriched lessons, a cellphone ban will affect schools very differently depending on where students live, Estaiteyeh says. 

    As Ontario has had restrictions on in-class phone use since April 2024, Estaiteyeh also questions what a ban on school properties would change in practice, and whether evaluation data from the 2024 policy is available to inform the expansion. 

    “Are we building on evidence or moving ahead of it? We need more details on who will enforce these rules and how,” he says. 

    Social media bans in schools are also a pressing topic for education systems across Canada, evidenced by Manitoba’s recent announcement it will ban social media and AI chatbot use in classrooms.  

    Estaiteyeh says he supports restricting social media in classrooms as the evidence is strong enough to act on — but not as a standalone measure. 

    “Without enforceable guardrails on the tech companies themselves, age bans are easy to circumvent. Students find workarounds, and we know this,” he says. “A ban without platform accountability is largely symbolic.” 

    Professor of Educational Studies David Hutchison agrees, adding that schools have a role to play in helping students understand how addictive cellphones and social media can be. 

    “The Ontario curriculum should address this topic directly in health and physical education and other subject areas,” he says.  

    Mixed messaging around AI and educational technologies (edtech) is also causing confusion for educators, policymakers and families.  

    “Ministries are simultaneously banning personal devices yet rolling out AI tools in classrooms and announcing more investment in STEM (science, technology, engineering and mathematics) education where technology is crucial. This messaging is inconsistent,” Estaiteyeh says. 

    He says Manitoba’s recent announcement provides an example, as it bundled social media and AI chatbots together.

    “Social media and AI are very different technologies. Treating them as a single category risks bad policy in both directions, under-regulating social media while over-restricting AI tools,” he says.  

    Each technology has its own benefits and risks, Hutchison adds, and they must be separately assessed.

     

    Mohammed Estaiteyeh, Brock Assistant Professor of Digital Pedagogies and Technology Literacies, and David Hutchison, Professor of Educational Studies, are available for media interviews on this topic.

  • Brock researchers make quantum leap to improve cancer care, communications technologies

    MEDIA RELEASE — APRIL 16, 2026 — R0035

    Driven by the stark reality that two out of every five Canadians are expected to be diagnosed with cancer in their lifetime, Travis Dudding has made it his mission to improve early detection through advanced imaging technologies.

    The Brock University Professor of Chemistry, working with collaborators at Johns Hopkins University, is developing new molecular imaging agents that circulate through the body and illuminate biological processes. This will allow clinicians using positron emission tomography (PET) scans to visualize tissues and disease sites with greater accuracy.

    PET scans are powerful diagnostic tools that reveal the body’s molecular and cellular activity. By capturing these processes in real time, they play a critical role in diagnosing and managing complex diseases such as cancer, says Dudding. 

    Dudding’s work is being supported by funding announced April 16 under the Natural Sciences and Engineering Research Council of Canada’s group of Alliance Grants.

    Brock Associate Professor of Chemistry Jianbo Gao also received two Alliance International Catalyst Quantum grants. The three grants total $75,000.

    “These prestigious awards recognize the world-class quality of Dr. Dudding’s and Dr. Gao’s work in quantum computing, materials and communications,” says Brock University Vice-President, Research Tim Kenyon. “Through partnerships across sectors and borders, our researchers are applying their innovations to meet emerging global and national challenges that have wide-ranging impacts in health care, industry and many other sectors.” 

    Dudding’s collaboration focuses on PET’s imaging agent, which enables the body’s internal structures to be seen more clearly. Bioimaging is enabled by incorporating fluorine-18 into biomolecules such as carbohydrates, lipids, proteins and nucleic acids. However, these fluorine-18–labelled biomolecules are often unstable, leading to reduced image clarity and, in many cases, fuzzy results. 

    Dudding, Johns Hopkins Assistant Professor of Radiology and Radiological Science Laurence Carroll and their graduate students are using artificial intelligence and quantum computing methods to create a new molecule that will carry fluorine-18.  

    “The end result is that we can diagnose cancers more effectively and faster, which is going to save human lives in Canada and throughout the globe,” says Dudding. “I’m excited to use my knowledge and interest in chemistry to make diagnostic tools that doctors use to treat patients.” 

    Meanwhile, Gao’s research focuses on advancing next-generation quantum sensing and quantum computing technologies.

    In these technologies, particles made from light, electric currents, magnetism brought about by electrons spinning, and temperature-related atomic vibrations interact with each other at “ultra-fast” speeds in quantum devices.

    In one project, Gao is collaborating with Clément Livache at École Polytechnique in France to develop qubits — the basic unit of information in quantum computing — that can operate at room temperature. Currently, qubits are formed and operate in very cold temperatures. 

    “Qubits functioning at room temperature is a key step toward practical quantum computing,” says Gao. “This allows for dramatically increased computing power and much faster data processing.”

    In another project, Gao is working with Sohee Jeong at Sungkyunkwan University in South Korea to develop advanced sensors based on nanocrystals. These materials enable the detection of extremely weak or invisible light, opening new possibilities for imaging, communication and security technologies.

    “These quantum technologies have the potential to enable scalable, low-cost and energy-efficient devices,” says Gao. “They will play a key role in strengthening Canada’s leadership in quantum innovation, supporting industry growth and training the next generation of highly skilled researchers.” 

    NSERC’s Alliance International Catalyst Quantum grants seek to support partnerships between Canadian researchers and international collaborators.

    Chris Bittle, Member of Parliament for St. Catharines, says Brock University’s quantum researchers are among scientists across the country who are positioning Canada to be “a leader in quantum research.” 

    “Quantum technologies, developed through the study of systems at the atomic and subatomic level, support the growth and transformation of key sectors and advance the range of benefits for society,” he says.
