This guide focuses on the first presentation for LS100 students, not the written proposal, which is covered separately. It is intended for the 15-minute group talk you give at the very start of the semester. It assumes you have already worked through Research Methodologies: Converting the Problem to a Research Framework (Guide 00) in this module — this talk presents that framework rather than builds it.

In this talk, you do not need to show results as you have not run the study yet. It is rather intended to present your idea, the question or problem you want to solve, and the research plan in a coherent way, and getting feedback before you begin the research. Build the talk to invite questions, not avoid them. Keep it to a maximum of four slides — below is what each slide may cover, and how to present well.

Your four slides

SlideContent
1The overarching question — and why it matters
2Your specific aims and hypotheses / target
3Methodology and data — how each dataset answers an aim / serves the target
4Possible outcomes, and back to the bigger question

This structure mirrors how NIH grant applications begin: a one-page “Specific Aims” section that states the problem’s significance, lays out the aims and hypotheses, and closes by pointing to the expected impact (National Institute of Allergy and Infectious Diseases (NIAID), n.d.).

1. Defining and framing the problem

Slide 1

For the talk: Open with a short story — what’s known or agreed on (the “and”), the tension or gap (the “but”), and what you propose to do about it (the “therefore”). One well-crafted sentence like this can carry the whole slide (Olson, 2015).

2. Breaking down the problem: specific aims and hypotheses

Slide 2

For the talk: Keep this to two aims. Limiting the presentation to two aims makes the project feel focused rather than unfocused, even when the underlying research is ambitious. This is what NIH suggests to the grant writers as well (National Institute of Allergy and Infectious Diseases (NIAID), n.d.).

3. Focusing on one achievable goal: Methodology and data structure

Slide 3

For the talk: You may show this as a diagram or infographics - for example, a flow showing how each specific aim connects to the relevant dataset and method. A figure someone else could present without you standing there is doing its job; if it takes more than a few seconds to read, simplify it (Midway, 2020).

4. Possible outcomes and the bigger picture

Slide 4

For the talk: Close by answering the “who cares” question you opened with. Compressing a research question and its stakes for a general audience in a few minutes is a real, transferable skill that I would like you to gain from this exercise.

Delivering it well

Before you present: a quick self-check
