About me

A global educator with deep roots in every classroom

I am Hacer Uygun Aydogan — a TESOL-certified educator, teacher trainer, and aspiring leader with 15 years of experience across four countries. My journey began in 2010 and has taken me from Hungary to Venezuela, Iraq, and now Cleveland, Ohio, where I serve at HSA Denison Middle School.

"I have taught in four countries, spoken three languages in classrooms, and looked into the eyes of over 400 children. In every face I saw the same thing — a child who needed someone to believe in them. That is why I lead."

Leadership philosophy

What I believe about schools

Shaped by classrooms on four continents, my leadership is grounded in four beliefs that guide every decision I make.

Relationships first

Having taught across cultures and languages, I know that trust is universal. Before we can lead or teach — we must truly know the people we serve.

Equity in everything

I have seen what inequality looks like in classrooms around the world. Every child deserves the same fierce belief in their potential.

Lifelong learning

I am a lifelong learner and reader. I model what I ask of my students and teachers — curiosity, humility, and the courage to keep growing every single day.

Global perspective

My four countries and three languages have taught me that great teaching transcends borders. I bring that international lens to every school community.

Harvard course

Harvard Graduate School of Education

As part of the Concept Schools Aspiring Leaders Program Cohort II, I completed the Leading Learning: LCMSL course through Harvard Graduate School of Education. All 4 modules completed at 100% — every one submitted ahead of deadline.

Harvard Graduate School of Education  ·  100% Complete

Leading Learning: LCMSL

A rigorous, research-based course exploring what it means to build and lead high-performing schools — systems alignment, school culture, teacher development, and learning beyond the classroom.

Program: Aspiring Leaders Cohort II  ·  February – March 2026  ·  All 4 modules submitted early

🎓

The 4 modules

1
Systems-Wide Alignment for Excellent Teaching and Learning
Submitted Feb 23  ·  Deadline Feb 25  ·  2 days early
100% ✓

This module explored how school leaders create coherent, systems-wide conditions for excellent teaching and learning. I examined how alignment across curriculum, instruction, and assessment creates consistency — and how a principal's role is to build structures that allow every teacher and every student to succeed. I reflected on how my multilingual, multicultural background gives me a unique lens for understanding diverse needs within a school system.

2
Creating a Strong Instructional and Caring Culture
Submitted Feb 27  ·  Deadline Mar 4  ·  5 days early
100% ✓

This module deepened my understanding of what it means to build a school culture that is both academically rigorous and genuinely caring. Instructional culture and school climate are not separate — they are the same thing. When students feel safe, known, and valued, they learn better. When teachers feel supported and trusted, they teach better. I connected this deeply to my belief that relationships are the foundation of all effective leadership.

3
Developing Your Teachers and Teacher Leaders
Submitted Mar 2  ·  Deadline Mar 11  ·  9 days early
100% ✓

Having been a teacher trainer myself, this module resonated with me deeply. I explored frameworks for observing, coaching, and developing teachers at different stages of their careers — and how to identify and nurture teacher leaders within a school. I reflected on my experience coaching teachers across four countries and how those coaching conversations, done with respect and care, are the most powerful professional development a school can offer.

4
Teaching and Learning Beyond the Classroom
Submitted Mar 5  ·  Final Deadline Mar 18  ·  13 days early
100% ✓

The final module challenged me to think beyond the four walls of the classroom — exploring how schools connect to families, communities, and the broader world. As someone who has lived and taught across four countries, I know that learning happens everywhere, and that a school's impact extends far beyond its building. This module reinforced my commitment to family engagement, community partnerships, and schools that see themselves as the center of their communities.

What I am taking away

All four modules completed at 100% — all submitted ahead of deadline. The course deepened my conviction that great school leadership is about building systems, culture, and people simultaneously. I am a lifelong learner and this Harvard experience confirmed that the best leaders never stop growing.

How I am applying it

The LCMSL frameworks are already shaping how I think about teacher development, instructional culture, and family engagement at HSA Denison — a more structured, research-grounded approach to coaching conversations, observations, and building community connections.

Shadowing experiences

Learning by watching great leaders

Shadowing principals and instructional leaders has been one of the most powerful parts of this program. The program requires a minimum of 3 experiences across critical roles: Principal, APA, APSC, and APO.

Shadowing Experience 1 of 3 · April 2, 2026

Principal John Cameron — Horizon Science Academy Denison Middle School (K–8), Cleveland, Ohio

I spent a full day alongside Principal John Cameron observing how a principal manages the many responsibilities of school leadership. My focus areas were school culture & climate, teacher support & development, data-driven decision making, and leadership communication.

8:30 – 9:00  ·  Morning Announcement

Students led the morning announcement with Principal Cameron creating a positive, encouraging environment. He read a first grader's writing aloud to celebrate and motivate the whole school. I learned that recognizing student work publicly builds confidence and creates a strong school culture.

9:00 – 9:45  ·  Q&A Session with Principal

Principal Cameron openly shared how school leadership works — including which information is shared with teachers and what must remain confidential. He discussed plans for peer observations and using data to make decisions.

9:30 – 9:50  ·  Student Support Interaction

The principal worked with a student who did not want to complete a writing task — calmly trying to understand the reason and encouraging completion. Leadership involves direct interaction with students — encouragement and patience are just as important as any strategic decision.

10:00 – 10:45  ·  Teacher Interview (Grade 5 Math)

The principal followed a structured interview with prepared questions and was fully honest about the school's demographics and expectations. I learned that honesty and clarity during hiring ensures the right fit for the school community.

11:00 onwards  ·  Managing Communication

Principal Cameron continuously responded to calls and emails while managing all other responsibilities. The role requires exceptional multitasking, organization, and the ability to stay calm under constant pressure.

Reflection: What surprised me most was how busy and unpredictable the principal's day truly is. Many decisions are invisible to teachers and some must remain confidential. I will adopt building a positive school culture, peer collaboration, supporting teachers individually, and using data to make informed decisions. Growth areas identified: school culture & climate, data-driven decision making, leadership communication, and teacher support & development.

Shadowing Experience 2 of 3 · April 27, 2026

Principal Bilgehan Aslan — HSA Cleveland Elementary School

I spent a full day at HSA Cleveland Elementary shadowing Principal Bilgehan Aslan. This school has a very different demographic profile from my own — approximately 97% homogeneous — giving me insight into how leadership adapts based on student population, community needs, and cultural context.

7:30 – 8:00  ·  Teacher Contract & Department Head Appointment

The principal discussed a formal agreement with a teacher being appointed Head of Science, clearly communicating expectations and offering additional compensation — while also actively listening to an ongoing concern she had from a conference. A powerful balance of accountability and care.

8:30 – 10:30  ·  Q&A with Assistant Principal & Classroom Walkthroughs

The AP manages overlapping ELA, Math, and TBTA meetings by rotating — spending about 10 minutes in each. During a Grade 5 Math walkthrough, I observed a teacher using visuals, clear board questions, and independent worksheets. Collaborative leadership means sharing the load.

10:30 – 12:00  ·  Administrative Team Meeting

The team covered a structured agenda: attendance, Teacher Appreciation Week, Kindergarten graduation, 8th grade prom, a music concert with food truck, summer school for 3rd graders (June 1–15), and ISS policy revision. Decisions were collaborative, data-informed, and clearly assigned.

1:00 – 1:30  ·  Student Motivation Lunch & Speech

The principal gathered students in the gym for a motivational speech ahead of testing week using call-and-response: "Who is the best?" / "We are the best!" Students were treated to hotdogs and hamburgers. Celebrating students and framing tests as opportunities creates a positive, motivated culture.

1:40 – 2:40  ·  Meeting with Concept Schools Chief Operations Officer

Discussed enrollment (goal: 255, currently 10 short), PowerSchool and Schoology usage, safety measures including a new metal detector, building improvement needs, and the principal's parent advocacy group — monthly meetings, dinners, and a plan to build a natural garden with parents.

Reflection: I was moved by how the principal balanced being firm and accountable while remaining deeply empathetic. I will take away active listening before deciding, using data to guide improvement, building a parent advocacy group, and maintaining strong visibility through walkthroughs. This deepened my understanding of how leadership adapts to different school demographics.

Shadowing Experience 3 of 3 · May 5, 2026

Principal Sevket Simsek — HSA of Lorain (K–12), Lorain, Ohio

My third shadowing took me to HSA Lorain — a large K–12 school with 827 enrolled students and over 200 on the waiting list. A full administrative team of 7 people in clearly defined roles. Principal Simsek gave me a complete picture of distributed, structured leadership at scale.

8:00 – 9:00  ·  Morning Building Walk

We walked through every classroom in the K–12 building — greeting every student and staff member individually. Because there are 3 classes per grade level, this took a full hour. Visibility is not optional in leadership — it is a daily, deliberate commitment.

9:00 – 9:30  ·  Certification Celebration with 3rd Graders (APA K–5)

The APA personally served each child a donut, lined them up for a class photo, and made every student feel seen. When one child became upset because his favorite donut was unavailable, she responded with complete calm — a masterclass in emotional intelligence.

9:30 – 11:00  ·  Full Administrative Team Meeting (7 members)

The 7-person team — Principal, two APAs, two APSCs, APO, Student Services — each presented their section from a shared Excel file. Topics: enrollment at 827 with 200+ on the waiting list, middle school behavior, Meta glasses ban, Quizizz research approval, 112 SPED students, 140 ESL students, new security cameras, and a $400 leadership camp approved for the counselor.

11:00 – 12:30  ·  Time with the APA (K–5) — Behind-the-scenes Academic Management

In a single morning the APA managed the substitute schedule, monitored a visual plan period wall, tracked reading completion by walking the hallway chart, prepared raffle tickets for every class, emailed teachers about failing students, printed retention letters requiring parent signatures every quarter, and emailed summer school referrals. The quarterly retention letter system — requiring parent signatures — was a revelation in proactive communication and school protection.

1:00 – 2:30  ·  Principal's Office, Classroom Placement & Dismissal

A math teacher requested support attending a competition in Columbus. The principal asked directly: "Is this useful for you?" — approving only after she explained the genuine value. During dismissal, he walked every exit door one by one. He then explained teacher improvement plans, noting that cultural and language gaps in understanding formal processes are a leadership responsibility to address.

Reflection: This experience completely changed how I picture school leadership. What I saw at HSA Lorain was far more complex — a carefully structured team where every person had a role, every decision was intentional, and leadership showed up in small moments just as much as big ones. I will carry a commitment to celebrating students personally, asking whether decisions are truly useful before committing, staying calm in conflict, distributing leadership across a strong team, and building systems — not just making individual decisions.
