Field vs. Laboratory Research

Research is the cornerstone of expanding our knowledge and understanding of the world around us.

Field research is the collection of raw data outside a laboratory, library, or workplace setting. It aims to capture the authenticity of real-world interactions, making it particularly suitable for studying social behaviors, ecological systems, and cultural dynamics. Researchers gather data through methods like observations, surveys, interviews, participant observation, and ethnography. This approach provides a holistic perspective on the studied phenomena, shedding light on various involved factors and enabling exploration within their natural settings.

On the other hand, lab research takes place within controlled laboratory environments. This controlled setting enables researchers to manipulate variables precisely and systematically, facilitating the establishment of cause-and-effect relationships. Controlled experiments, simulations, and controlled observations are commonly employed in lab research. This approach is well-suited for isolating specific variables, making precise measurements, and conducting experiments with a focus on internal validity.

The advantages of field research

Field research comes with notable advantages. It allows researchers to observe phenomena in their natural complexity, capturing interactions that might be difficult to replicate in a lab setting (ex. archaeology, sociology, any kind of cultural or social construct, etc.). The findings often possess high ecological validity, making them applicable to real-world situations. Yet field research has its own limitations. The lack of control over external factors can introduce confounding variables, and the process can be resource-intensive and time-consuming due to logistical challenges. It can be hard to isolate singular phenomena when there are dozens of other factors accounted for but not managed.

The advantages of lab research

The strength in lab research is in its ability to control variables and minimize external influences, resulting in enhanced internal validity. Replicating experiments is relatively straightforward, increasing the confidence in the findings. Factors are accounted for and controlled, allowing for the elimination of most confounding variables. Nonetheless, lab research has its own set of limitations. Controlled environments might oversimplify the complexities of real-world phenomena, potentially leading to demand characteristics or a lack of ecological validity. Sometimes these confounding variables are integral for the phenomena to happen, and without these variables at play, the experiment itself may be oversimplified. Moreover, some phenomena, particularly those deeply embedded in natural contexts, cannot be accurately studied in lab settings.

What kind of research am I doing for my project?

Determining the appropriate approach depends on the research objectives, the nature of the studied phenomena, available resources, and ethical considerations. Field research shines when exploring intricate social interactions, studying ecosystems, and investigating cultural phenomena. Meanwhile, lab research is valuable for establishing causal relationships and isolating variables under controlled conditions.

In practice, researchers often blend these approaches to maximize their insights. Field observations can inform the design of lab experiments, while lab findings can be tested and validated in real-world scenarios.

Considering cost and resources, field research often demands more due to travel, equipment, and logistical requirements. On the other hand, lab research can be cost-effective in terms of equipment and personnel, but it might involve significant initial setup.

Validity and reliability are key considerations. Field research prioritizes external validity and naturalistic settings, possibly at the expense of internal validity. In contrast, lab research emphasizes internal validity while potentially sacrificing ecological validity.

How to read a manuscript

Conducting a literature review is a critical aspect of any research project. It involves systematically gathering, evaluating, and synthesizing existing research and publications relevant to your study in order to build upon previous knowledge or gather evidence for/against your own paper or experiment. In this comprehensive guide, we will provide step-by-step instructions and essential tips for conducting a literature review.

The general outline for any manuscript is as follows, starting from the top:

Literature Review:

Step 1: Define the Scope and Research Questions: Clearly define the scope of your literature review and the specific research questions you aim to address. This will help you stay focused and avoid getting overwhelmed with irrelevant information.

Step 2: Identify Keywords and Search Databases: Develop a list of relevant keywords related to your research topic. Utilize academic databases such as PubMed, Google Scholar, Scopus, and Web of Science to conduct your literature search.

Step 3: Review Abstracts and Titles: Scan through the abstracts and titles of the retrieved articles to assess their relevance to your research questions. abstracts are essentially condensed summaries of the paper, allowing you to understand the basic purpose of the paper without needing to read the entire thing.

Step 4: Read Full-text Articles: Carefully read the full-text articles of the selected papers. Each person has their own way of reading and understanding papers, but we recommend this reading order:

  1. Abstract. This will allow you to understand the basic purpose of the paper first, so you know what you’re getting into.
  2. Results. Results are often at the end of the paper, but that doesn’t mean you should read them last. Knowing what the results are first will allow you to understand more thoroughly the methodology and discussion.
  3. Everything else. After the abstract and results, then go back to read the paper in order (methodology, results, discussion, etc.

Make sure to take comprehensive notes and identify key findings, methodologies, limitations, and gaps in the literature. Look up any words or concepts you don’t know!

Step 5: Analyze and Discuss Findings: Analyze the literature critically. Try to find gaps or limitations in their research, or compare and contrast with different studies.

Extra tips:

  • Stay updated with the latest research by setting up alerts for relevant keywords.
  • Consult with your mentors or peers to get insights and recommendations on relevant literature.
  • Be objective and avoid bias when evaluating and interpreting the findings of different studies.

How to: prepare for your first day in the lab + what to expect

So, you’ve got the position – congratulations!

Preparing for your first day in a research lab as a high school student can be both exciting and nerve-wracking: there will be a lot of questions and information thrown at you. Here’s a guide on how to prepare for your first day and what to expect coming in.

Before your first day

Your first day will most likely be agreed upon a few weeks after your PI’s agree to have you, so here’s what you can do in the time before you go in:

  1. Review basic science concepts. Brush up on fundamental science principles related to the lab’s field. For example, if you’re doing neuroscience, you’ll want to know basic brain function and anatomy. If you’re going into bioinformatics, you’ll want to know some basic biology and programming skills. This will help you understand discussions and experiments more easily without having to spend too much time catching up on basic ideas. But, don’t worry if you don’t understand everything! It’s important to note that your PI’s are not expecting you to know everything on the first day. You’re going into the lab to learn, not to review!
  2. Review the lab’s most recent publications. Their lab website will most likely have a link to all of their downloadable publications, so you’ll want to download them and review their most recent papers. You don’t have to understand every minute concept in the paper, but it’s good to get a general grasp on their latest projects and areas of interest. If they don’t have a link to their publications, you can email them and ask for any papers they think will be important to read beforehand.

Most labs will have a list of their publications, free to download!

  1. Plan your transportation. If you’re going to an area you’ve never gone before or the lab building is in an obscure location, make sure to plan your way there beforehand – you can use Google Maps, or even go there a day before to plan out your route. It’s best to know how to get there before you actually go in, just in case you get lost or get stuck in traffic.

On your first day

Today’s your first day! Here’s what you need to do right before you leave:

  1. Dress Appropriately: All labs require lab-safe clothing, so this means no open toed shoes and no overly loose clothing or jewelry/accessories. Wear appropriate clothing you’re comfortable in, as you’ll most likely be there for many hours. If you’re unsure about any specifics, don’t be afraid to ask once you get there!
  2. Pack essentials. Pack a small backpack with items you’ll most likely need:
    • notebook
    • laptop
    • pens + pencils
    • calculator
    • water (in a closed bottle) and a snack or lunch
    • USB drive (not necessary, but always good to have just in case)
    • any other materials your PI’s have specifically asked you to bring
  3. Leave your house early. It’s always best to give yourself some buffer time in case traffic gets bad, you get lost, or anything that might prevent you from arriving on time.

What to expect going in

Most labs will not have you starting anything complex on your first day. Don’t expect to be doing any crazy complex work right off the bat. You can most likely expect an orientation: they’ll give you a tour of the lab, introduce you to your now colleagues, give you a lecture on any important concepts, and update you on their current projects. Make sure to have a notebook/laptop handy to take notes.

You will most likely be shadowing someone in the lab. Even before you come in, your PI’s will have most likely paired you with someone working in the lab, either an undergraduate student, PhD student, or postdoctoral researcher. This is your direct mentor. After you’ve gotten orientated around the lab, they will take you to meet your direct mentor (or maybe they’re the one who gave you the tour) and they will explain their project to you. They will have experiments already running, so you’ll most likely be following them around and helping them out with different parts (ex. learning to pipetting their solutions, plate bacteria, incubate cells, etc.).

For the first few weeks, you’ll only be helping out. You’ll shadow your mentor for a few weeks until you get comfortable being independent around the lab and doing various aspects of an experiment, at which point you’ll transition into your own independent project. It will most likely be a subproject of your mentor’s, who’s probably working towards their PhD or any type of thesis project.

Remember, each lab has their own environment, culture, and rule set. If you’re unsure about anything, do not be afraid to ask questions! Your mentors will want to see that you’re not afraid to ask for help and that you’re intellectually curious. Always ask why!
