How teachers shape student potential in diverse classrooms.

Pull up a chair, let's talk. I believe education can change the world — and that every child deserves equal opportunities to thrive. My doctoral work explores how teachers are linked to students' academic achievement and ethnic prejudice in ethnically diverse classrooms.

Hello, I'm Linh-Ha

A knowledge seeker, educator, and PhD researcher in the Center for Social and Cultural Psychology at KU Leuven, supervised by Prof. Dr. Jozefien De Leersnyder and Dr. Roy Konings. I joined the lab in April 2026, and my work sits at the intersection of educational psychology, intergroup relations, and teacher research.

My current PhD project is an attempt to arrive at an integrated understanding of what teachers do, why they do it, and under which conditions their diversity practices (School Diversity Models, SDMs) promote educational equity and reduce ethnic prejudice.

The road here

My path winds through three continents. I had my bachelor's degree at Foreign Trade University in Vietnam, then earned a Master's in Adult Education at the University of South Florida in the U.S., and most recently completed my Master's in Educational Studies at KU Leuven in Belgium, where my thesis on pluralism (i.e., schools and teachers value students' diversity — one type of School Diversity Models) and ethnic prejudice in secondary schools became my first first-author paper, currently submitted.

Why this project

As a Hmong woman myself, this research is deeply personal. In 2018, I founded Quy Van Hoa Mong (The Hmong Cultural Foundation) to promote indigenous Hmong cultural values and support students reconnecting with their quickly-eroding cultural roots. The same year, I started Morning Glory English — providing free English classes to high school students from disadvantaged and ethnic minority backgrounds in Vietnam. These experiences taught me, viscerally, that education can change the world — and that everyone deserves equal educational opportunities. And just as importantly, they showed me that the role of the teacher is profoundly important in shaping how students think and feel about their own learning.

Beyond the desk

When I'm not working on this project, I run a YouTube channel with 11.9k+ subscribers sharing educational and learning-related content. I've taught for 10 years across the US, South Korea, and Vietnam — from 5-year-old Spanish-speaking immigrants to university students. I care about making research findings accessible to the people they affect most: teachers, students, and families.

Chapter Two

The research

Academic achievement shapes future life chances, and knowledge economies depend on all youth realizing their potential. Yet, minoritized students do not have equal opportunity to thrive.

Three approaches to diversity — School Diversity Models (SDMs)

no. i

Pluralist SDMs

Actively values diversity as a resource for learning and connection.

↓ Prejudice · ↑ Achievement
no. ii

Color-blind SDMs

Ignores or downplays diversity in favor of treating everyone the same.

Mixed findings
no. iii

Assimilationist SDMs

Reduces diversity by expecting adaptation to the majority culture.

↑ Prejudice · ↓ Achievement

Three objectives

i

The first

Longitudinal effects

Examine longitudinal associations between teachers' SDMs and changes in students' outcomes over time.

ii

The second

Combinations & profiles

Identify how teachers combine diversity approaches (into distinct "teacher diversity profiles") and how these combinations predict changes in student outcomes.

iii

The third

Why teachers do what they do

Examine the individual, contextual, and narrative factors underlying teacher diversity profiles.

Brief entries from the long road of doctoral work — what I am reading, what I am writing, where I am stuck, and the small joys along the way.

22 May 2026 Conference week

Presenting at BAPS — my first conference as a PhD

Today I'm presenting my poster at the Belgian Association for Psychological Sciences. It feels surreal — I officially started my PhD just over three weeks ago, on 29 April. The poster lays out my full conceptual model: three objectives, two datasets, three work packages. The conversations with colleagues stopping by have been generous and challenging in the best ways.

The PhD officially begins

Today is my first official day as a PhD student at KU Leuven. After months of preparation, the proposal is approved and the work begins. Four years stretch ahead — three work packages, four planned papers, and an enormous amount to learn about Latent Profile Analysis, longitudinal multilevel modeling, and Kelchtermans' Personal Interpretative Framework. I am grateful, and I am ready.

February 2026 Workshop · Germany

Co-facilitating in Germany

Spent days in Germany co-facilitating a discussion at the workshop on ethnic-racial socialisation in minoritized European families. So many questions about how families and schools jointly shape children's understanding of who they are. The conversations are still echoing in my head.

November 2025 Fieldwork · Vietnam

Two weeks in the mountainous villages

Conducted semi-structured interviews with six teachers in rural village schools in Vietnam — over 95% of their students come from minoritized and disadvantaged backgrounds. I conducted field visits to rural village schools with a local guide, observing teachers' working contexts and community conditions in areas with developing infrastructure. Through this project, I have enhanced my skills in semi-structured interviews, fieldwork organization, and, most importantly, it has taught me how to conduct myself ethically and personally with the most vulnerable populations, where my research hopes to support.
