Kako odabrati temu diplomskog rada

Choosing a topic seems like the first step, but it actually lays the foundation for everything that follows. A good topic determines how much you'll enjoy the process, how good the paper will be, and how motivated you'll feel the moment you get stuck on the 23rd source about some minor side effect. A poor topic choice means months of struggle; a good one means work that flows.

In this guide we walk through the approach that has proven most reliable in our practice: a combination of personal interest, academic feasibility, and research originality. All three criteria must be met — neglecting any one of them leads to problems later.

1. Start from interest, not the mentor's list

Many students approach choosing a topic by reading their mentor's list of suggested topics. This approach has one fundamental flaw — it picks a topic before you've thought about what interests you. The result: months of work on something objectively distant, boring, or entirely someone else's idea.

It's better to start in the opposite order. Ask yourself:

• Which topic within your field has always interested you — and what do you enjoy reading about in your free time?
• Which question from practice or everyday life genuinely intrigues you?
• What could you talk about with friends for 30 minutes without checking the clock?

This isn't a sentimental recommendation — it's a practical one. Writing a thesis takes months. If the topic isn't one that intrinsically interests you, you'll simply give up the moment it gets hard. And it always gets hard.

2. Check feasibility

A brilliant topic that requires access to archival materials in Vienna, interviewing 200 respondents from a specific population, or six months of fieldwork — probably isn't feasible within the scope of a thesis. Ask yourself:

• Do you have access to data? Will your faculty, institution, or company give you access to the information you need?
• Postoji li dovoljno literature? A topic that is too little researched is difficult for a thesis — without prior sources, it's hard to build your theoretical framework.
• Do you have the time? Realistically assess how many hours per week you can devote to the work and whether your topic's size fits that schedule.

"The best paper isn't the one that tackles the most complex topic, but the one that clearly answers a carefully posed question."

3. Find focus, narrow the topic

The most common student mistake is choosing too broad a topic. "The impact of social media on young people" sounds like a good topic, but it's too much. What exactly do you mean by "impact"? Which social media? What age? In what context?

An exercise we recommend: take your initial topic and ask yourself "who," "what," "when," "where," and "why":

• Initial topic: The impact of social media on young people
• Narrowed: The impact of Instagram on the self-confidence of girls aged 15-19 in Croatia
• Even more focused: The correlation between time spent on Instagram and self-assessment of body image among female high school students in Zagreb

The third version is research-clear — you know what to measure, whom to survey, and how to interpret the results.

4. Talk to your mentor — but come prepared

Before you go to your mentor, prepare three versions of your idea. Present them as a choice — don't ask them to pick a topic for you, but to react to your ideas. Your mentor will tell you which are feasible, which already exist, and which have potential.

Bring to the meeting:

• Three short topic outlines (3-4 sentences each)
• A list of the first 5-10 sources you found for each
• A clear research question for each topic
• Thoughts on methodology (how you would approach it)

This shows you're serious and saves your mentor's time — the fastest way to get quality feedback.

5. What to avoid

Some types of topics almost always lead to problems:

• Over-researched topics — if you find 200+ papers from the last 5 years on Google Scholar for your topic, it will be hard to find an original angle.
• Overly general topics — "Marketing in the 21st century" isn't a thesis, it's a textbook.
• Teme ovisne o jednom izvoru — if all knowledge of your topic comes from a single book, try to broaden it.
• Teme bez literature — extremely specific, new, or niche topics may not have enough academic sources for a solid theoretical framework.

In conclusion

Choosing a topic isn't a careless decision made at the last minute — it's a strategic step that shapes your entire upcoming period. Devote time to it. Think. Talk to your mentor, friends, and people in the field. Read a few abstracts of academic articles in the area that interests you.

And, most importantly — choose a topic that will make you want to return to your work, even when it gets hard. Because it will get hard. But if the topic is right, it will be worth it.
