Technology is woven into nearly every aspect of education, making Acceptable Use Policies (AUPs) essential for guiding responsible use. At my school, our AUP lays out clear expectations for students, but like many policies, it leans heavily on what they shouldn’t do rather than empowering them with best practices. The policy covers a wide range of digital behaviors, including internet usage, social media interaction, and device management. It is detailed and comprehensive, aligning with the requirements of the Children’s Internet Protection Act (CIPA) and addresses issues like cyberbullying, unauthorized access, and inappropriate content. However, it lacks substantial guidance on emerging technologies, most notably, Artificial Intelligence (AI). As AI tools become increasingly accessible, should our policy explicitly define appropriate AI use for learning? Without this clarity, students and faculty alike are left to navigate these tools without institutional guidance.

Faculty are also bound by an AUP, though it differs slightly from the student version. While we are trusted with more autonomy, the core principles remain the same. But are these policies comprehensive enough? And more importantly, do they adequately prepare us for the evolving risks of digital exposure?

The Reality of Data Exposure

To evaluate personal cybersecurity risks, I recently explored Have I Been Pwned, a site that reveals if an email has been caught in a data breach. What I found was unsettling: my personal email had been involved in three breaches, while my work email had been compromised six times. This raised immediate concerns. If my work credentials have been exposed that many times, what does that mean for my students?

Using this interactive tool, I traced the history of my data leaks. My first breach was in 2018 at Apollo, where information like my job title, email, and even social media profiles were exposed. A year later, LuminPDF followed, this time leaking passwords and authentication tokens. The breaches continued: People Data Labs in 2019, LinkedInScrape in 2021, and DemandScience in 2024. With each incident, more of my identity was exposed—email addresses, phone numbers, names, and job titles, all out there, potentially in the hands of bad actors.

This isn’t just an individual issue; it’s a systemic one. If educators and students aren’t actively protecting their data, we’re all at risk. Yet, our AUP barely touches on digital security beyond broad warnings against phishing scams. Shouldn’t we be teaching students how to actively safeguard their personal information?

Practical Steps for Stronger Security

After seeing my own data exposure, I turned to resources for improving security. One simple step is using stronger passwords. Instead of short, complex passwords that are difficult to remember, tools like Use a Passphrase generate long, easy-to-remember passphrases that are significantly harder to crack. Encouraging students and faculty to adopt passphrases over standard passwords could be a small but impactful addition to our AUP.

Additionally, we should explicitly incorporate guidance on managing personal data, recognizing the risks of data breaches, and using AI tools responsibly. Cybersecurity education shouldn’t just be an afterthought. It should be embedded into our policies and curriculum.

Moving Forward: Updating the AUP

Reflecting on my own experiences with data breaches, I feel a mix of anxiety and awareness. It’s unsettling to realize how much of my information has been compromised, but it also reinforces the need for vigilance. The reality is that we cannot simply abandon the internet; rather, we must take proactive steps to secure our digital presence. Just as we lock our doors or set house alarms for physical security, we must implement strong passwords, enable two-factor authentication, and remain cautious about sharing personal information online.

Our AUP should evolve to reflect this reality. We need to move beyond reactive policies that focus solely on restrictions and instead provide students and staff with actionable steps for responsible technology use. Cybersecurity experts, faculty, IT specialists, and even students should be involved in shaping these updates. A strong policy isn’t just about setting rules, it’s about equipping our school community with the tools to navigate an increasingly digital world safely and responsibly.

Math, Media, and Manipulation: Unpacking the Algorithms That Influence Us

Understanding Algorithms: A Math Teacher’s Perspective

As a high school math teacher, I’ve always been interested in algorithms. In the classroom, I teach students how to use step-by-step procedures to solve problems, like the long division algorithm for polynomials or the structured problem-solving methods in DeltaMath. But beyond math, algorithms shape nearly every aspect of our digital lives, from the videos we watch to the news we consume. This topic is especially relevant to me, not just as a teacher, but also as a parent.

My students are deeply engaged in social media platforms like TikTok, Snapchat, and Instagram. I often hear them discussing trending videos, viral challenges, and influencer drama. They don’t always realize how much of their experience is shaped by algorithms designed to maximize their time on the platform. At the same time, my 13-year-old recently got a phone and, while he doesn't have social media yet, he is an avid YouTube watcher. Since the content recommendations on platforms like YouTube, TikTok, Snapchat, Instagram, and Facebook are all algorithm-driven, I wanted to better understand how these systems work and what influence they have on both my students and my own children.

The Power of Algorithms in Digital Spaces

One of the most eye-opening resources I explored was PBS Learning Media’s discussion on YouTube’s recommendation algorithms. The video explains how YouTube prioritizes engagement, often pushing sensational or polarizing content to keep users watching. Even if someone starts watching harmless educational videos, they could quickly be led down a path of more extreme or misleading content. This made me think about my children’s viewing habits. While they mainly watch entertainment, video game walkthroughs, or craft challenge videos now, I need to be mindful of how the algorithm could steer them in unexpected directions.

Similarly, the Pew Research Center’s study on Facebook’s algorithms and personal data explores how social media platforms collect vast amounts of user data to shape the content people see. Many users assume their feeds are neutral reflections of reality, but in truth, they are highly curated by algorithms designed to keep engagement high. This is particularly concerning when I think about my students, who often take the information they see on TikTok or Snapchat at face value without questioning why it appears in their feed in the first place.

Another compelling resource I explored was the Most Likely Machine interactive experience (Artefact Group), which highlights how machine learning algorithms make predictions based on historical data and the problems that can arise when those predictions are flawed. One of the key takeaways from this resource is that algorithms do not have all the information; they rely on past data, which reflects human opinions and biases. As a result, instead of being purely objective, algorithms can actually reinforce and amplify existing biases. Even more concerning is that once an algorithm makes a prediction, whether correct or not, it tends to repeat and multiply its mistakes, further embedding bias into decision-making processes. This is especially relevant in areas like job hiring, policing, and education, where algorithm-driven systems can unintentionally deepen existing inequalities. In schools, adaptive learning platforms and AI-based grading tools may seem neutral, but if they are built on biased or incomplete data, they could unfairly advantage some students while disadvantaging others. While these technologies have the potential to improve learning experiences, they also raise important ethical concerns about fairness and accountability, reminding me that even in math, where algorithms are essential problem-solving tools, their real-world applications require careful scrutiny.

Implications for Teaching and Parenting

As a math teacher, I already incorporate algorithmic thinking into my lessons, however, this research has encouraged me to take it a step further. I plan to have more discussions with my students about how the algorithms that power their favorite social media apps work and how they can critically evaluate the content they consume. If they understand that their feeds are not just random but carefully curated based on their past behavior, they might become more skeptical and intentional about their online experiences.

As a parent, I am also more aware of how my children’s digital habits are being shaped by recommendation algorithms. While I have already made the decision to delay social media use, I now realize that YouTube’s algorithm can be just as influential. Moving forward, I plan to have ongoing conversations about why certain videos or recommendations appear, how to recognize algorithmic manipulation, and how to actively seek out diverse and high-quality sources of information.

Final Thoughts

What surprised me most was how little control users have over the algorithms that shape their online experiences. It’s easy to assume that we are making independent choices about what we watch or read, but much of what we see is curated behind the scenes. This has changed the way I think about algorithms. Not only will I be more intentional about teaching students to analyze and question algorithmic influence, but I will also be more proactive in helping my own children navigate an increasingly algorithm-driven world.

For educators, parents, and anyone navigating digital spaces, understanding algorithms is essential. I highly recommend checking out the sources I linked above to gain a deeper understanding of how these systems work. The more we know, the better we can equip ourselves and the next generation to engage with technology thoughtfully and responsibly.

Identifying with Identity: Technology, Collaboration, and Discovery

When reflecting on the four key areas of growth for educators that Professional Learning Networks (PLNs) provide (affective, social, cognitive, and identity), I identify most with identity because my teaching philosophy is deeply rooted in the integration of technology, collaboration, and discovery-based learning. As an educator, I strive to design lessons that not only engage students but also empower them to take ownership of their learning. Technology plays a crucial role in this process, serving as more than just a delivery tool for information; rather, it is a catalyst for creativity, problem-solving, and meaningful collaboration. My goal is to create an interactive, student-centered classroom where students feel motivated to explore, ask questions, and engage in critical thinking. By leveraging the right tools and fostering a collaborative learning environment, I aim to prepare my students for a world that increasingly values innovation and adaptability.

To expand my PLN and gain new insights, I participated in an activity that involved creating an infographic about PLNs. This hands-on experience allowed me to visualize and organize the key benefits of a PLN while reinforcing its impact on professional growth.

Professional Growth: Expanding career opportunities through networking and ongoing development.

As I worked on this infographic, I realized how much my own PLN has shaped my teaching practices. From learning about interactive digital tools to incorporating student-led projects, my PLN has been an essential resource in my professional journey.

Deepening My PLN Through Research and Exploration

As I worked on the infographic, I also took the opportunity to delve into new research and online sources that highlight the significance of PLNs in education. I discovered several insightful resources that provided valuable perspectives on how educators can build, maintain, and benefit from a strong PLN. Some of the most impactful sources included:

Edutopia’s article on using social media to build a PLN, which emphasized how platforms like Twitter, LinkedIn, and Facebook allow educators to engage in meaningful discussions and share ideas.

TeachHUB’s step-by-step guide to developing a PLN, which highlighted practical ways to start connecting with fellow educators through blogs, online courses, and professional organizations.

SimpleK12’s “10 Reasons Teachers Need a PLN”, which reinforced why building a PLN is crucial for staying inspired and connected.

ASCD’s guide on creating a PLN, which provided six actionable steps to develop and maintain a strong network.

The U.S. Department of State’s insights on PLNs, which discussed how they enhance teacher collaboration and professional growth on a global scale.

Each of these sources reinforced that a PLN is more than just a network, it’s a community. It’s about support, growth, and continuous discovery, and it plays a key role in shaping modern, technology-driven education.

Applying My PLN Growth to My Classroom

Reflecting on this experience, I’ve identified several ways to apply what I’ve learned to my teaching practice. I plan to engage more in social media discussions by actively participating in #EdChat on Twitter/X and joining Facebook educator groups to exchange ideas with fellow teachers. Additionally, I want to explore more collaborative EdTech tools like Flipgrid, Google Classroom, and Wakelet, which allow students to engage in discussions and projects beyond the classroom. Incorporating these tools effectively will enhance student collaboration and learning. Another area of growth is attending more webinars and virtual professional development sessions offered by organizations such as ISTE, EdCamps, and Google Educator Groups (GEGs), which provide valuable insights into emerging educational trends and technologies. Lastly, I aim to encourage my students to develop their own Personal Learning Networks (PLNs) by introducing them to educational blogs, discussion forums, and collaborative tools that foster independent learning and engagement. By implementing these strategies, I hope to create a more connected, innovative, and student-driven learning environment.

Final Thoughts: The Power of a PLN

This activity has reaffirmed the immense value of having a strong PLN. Education is constantly evolving, and by staying connected with fellow educators, I can continuously grow, learn, and innovate. My PLN is not just a conglomerate of resources and professional development, it’s a community of like-minded educators who share a passion for improving student learning experiences. Moving forward, I am excited to keep expanding my PLN, integrating more discovery-based learning strategies, and leveraging technology to create engaging, collaborative classroom experiences. If you are an educator and haven’t yet explored the power of a PLN, I encourage you to start today! What are your favorite ways to grow your PLN? Let’s connect and share ideas!

EXPERIENCE

I am in my 21st year of teaching mathematics, with three years at the junior high level and eighteen at the high school level, all within Catholic education. As a product of Catholic schools myself and a parent of children attending a Catholic school, I strongly believe in the value, impact, and unique opportunities that Catholic education provides. I have taught a range of courses, including Pre-Algebra, Algebra, Geometry, Algebra 2, and Precalculus, at both the college prep and honors levels. Currently, I teach Honors Algebra and Honors Advanced Algebra Trigonometry.

Over my career, I have witnessed and adapted to the evolution of classroom technology, from chalkboards and overhead projectors to document cameras, graphing calculators, iPads, and digital learning platforms. Transitioning from a paper-and-pencil environment to a fully 1:1 iPad classroom has been both exciting and challenging, but it has reinforced my commitment to engaging, innovative, and effective instruction.

TECHNOLOGY AND SOCIAL MEDIA IN EDUCATION

As technology continues to shape the educational landscape, I am particularly interested in how emerging tools, including artificial intelligence (AI), learning management systems (LMS), and social media, can enhance both instruction and student engagement. Currently, our school uses Blackbaud as our LMS, which offers expanded features and improved functionality to better support our school community. In my classroom, I use Blackbaud to organize and disseminate information, including posting guided notes, homework assignments, screencasts, and videos. Additionally, I incorporate Notability for guided notes and homework, ALEKS for personalized learning and assessment, DeltaMath for targeted skill practice, and TI-SmartView for calculator applications.

Integrating technology into a Catholic high school setting presents unique challenges. Limited resources mean that we do not always have access to the latest tools, and professional development opportunities focused on ed tech are scarce. Additionally, the deeply rooted traditions of Catholic education can make change slow. However, I believe that progress requires adaptability, creativity, and a willingness to take risks. Tradition, after all, is simply innovation that worked. This perspective fuels my excitement for this course on social media and emerging technologies. I look forward to exploring new ideas, tools, and strategies that will shape the future of education.

I have always found social media to be an interesting and powerful tool for communication, connection, and learning. While I like social media and appreciate its many benefits, I don’t use it very much in my daily life. Currently, I have a Facebook, X/Twitter account, and a LinkedIn profile, but that’s about it.

That being said, I am not opposed to social media by any means. I recognize its value in networking, staying informed, and engaging with different communities. I am open to trying or starting on other platforms in the future, especially as I continue to explore its role in education and emerging technologies.
