Enhancing the Effectiveness of Laboratory Reports: A Comprehensive Guide

1. Introduction to Laboratory Reports

The laboratory report is challenging to both the student and instructor. Traditional discussions about common student difficulties in writing scientific reports vary little; results tend to be written as a chronological account of what was done, lacking appropriate specificity about the scientific processes associated with the work. Protocol is often more seriously flawed, as students struggle with where the appropriate detail lies. Laboratory reports are challenging to students in two key ways. First, students have to learn scientific writing norms, which differ significantly from the norms they learned about papers elsewhere in high school and college writing. Topics that are considered vital and premature in a scientific paper are treated haphazardly in high school and college essays. Second, writing about lab experiments in science courses does more than reflect the norms of scientific writing, it acts as part of learning and understanding science and constitutes a valid mode for students to reflect back on the laboratory experience and extend it beyond data collection.

The laboratory report is a novel genre of writing that students must explore in their undergraduate and graduate careers. Thoughtful and thorough documentation of laboratory work is essential to any scientific endeavor, and students will initially experience writing for the laboratory as a mechanical, factual, and relatively uninformative experience. While there are professional benefits to this level of analysis, the ultimate goal of teaching laboratory reports is to provide students with a broader understanding of the scientific process. This understanding serves as the context for the course material, thereby enhancing student access to course content and their sensitivity regarding the relative importance of laboratory results.

2. Key Components of a Well-Structured Lab Report

Laboratory reports are important things that are written in biochemistry classes. They are measurements that allow the instructor to assess the student’s understanding of the class material in a hands-on, practical manner. In industry and graduate school, they will be called “professional” after writing about 100 of them. It is highly likely that for all professional activity a student new to industry or graduate school writes, the only reader will be the one who assigned the laboratory report. Note that at the undergraduate level, this is such an important writing skill and will count as such during a student’s career. With that reality, one can either just write reports or use the experience as training to become a professional writer. Hopefully, one becomes the latter.

Abstract: This module has been created to accompany foundational lab skills STM001 to enhance the students’ abilities to communicate through writing. In it, key structural writing components will be outlined. It provides guidelines for structuring papers, including discussions of the abstract, introduction, methods, results, and discussion sections. This section presents the guide for the laboratory reports that need to be completed by students to fulfill the course. Each of these sections is described here.

3. Best Practices for Data Analysis and Interpretation

Section 4: Data Sources. Paper sets the bar high for data sources. The best data source is convincing, comprehensive, and recent. Probably you shouldn’t (just) settle for what is available. Find the original data. A successful data source (DHW) will be documented, with a clear description of the sample and collection methodology. Consider visiting the data source; while there, look around and ask questions. What is the unit of observation or the unit of analysis? Collect and report your data (RD), explain subtleties, and recognize important outliers. Although the paper does not have an extensive prior literature, what work has been done before, often for related questions? Summarize the sources of, and methods underlying, the data collected, with some justification for using that data to answer the particular question of the paper. Follow a good data collection protocol and make sure data are collected in a consistent manner. Finally, openly discuss any unobservable features.

This chapter provides a detailed discussion of best practices regarding laboratory reports. Although the treatment is rigorous and detailed, we encourage focusing on selected parts. We want to provide guidance, not rules, and we recognize that approaches vary across fields and subfields. Aim for transparency and for convincing details and analyses. Strive to reflect our default assumption: the authors have considered many approaches and associated details and have finally reported good ones. Finally, get feedback: from peers, from the TAs, and from us. We say “Show, don’t tell,” so when feasible, put things in tables, calculations, or graphs. This approach can involve more work, but typically it also results in better papers.

4. Tips for Writing Clear and Concise Results

The word “results” also sometimes seems misleading to certain authors. To avoid this confusion, we encourage students to use words that better describe their findings, such as “the changes in enzyme activity”, “alterations in membrane permeability”, or “modifications in color”. Many beginning authors mislead readers by using misleading or passive verbs. The most effective and direct approach to writing a result section is to begin the section with a sentence that uses the most important findings. Then combine the most important visuals with this sentence. When combining data with the written word, use conservative wording. Mistaken interpretations often result when authors use emphatic terminology such as “dramatic”, “terribly”, “profound”, or “extreme”. Use these condemning words sparingly. Data tables and figures may also become more informative by incorporating clear, reusable data callouts with symbols, letters, and numbers. Callouts that include symbols, letters, and numbers strengthen the links between the findings and the result section. The presentation clarity and research quality almost always improve as a result.

We urge teaching assistants and faculty to do hands-on laboratory report training and to provide guidelines for clear, concise writing. Promote the understanding that readers may peruse your result section and immediately form a judgment about the importance of your findings. A clear, concise result section usually contains one or more of the following words: “demonstrated that”, “led to”, “show”, “indicate”, “imply”, “result in”, “enhance”, “exhibit”, “manifest”, “provide evidence”, and “resolved”.

5. Conclusion and Recommendations for Future Reports

Summary. Writing a laboratory report is a valuable chance to apply and consolidate the skills needed in many college and career fields. This step would be particularly easy if you know how to make it a pleasant, productive environment. Visitors can deliver a better system and spare comments when they have a straightforward procedure. In conclusion, the power of the audience is critical in considering what factors you need to do to prepare and compose a message. Build space for the whole plot and divide it into letters that the reader needs. If you do so, there is no doubt that your story will be easy to read.

The laboratory report is a record of the experiment you have completed and acts as the vehicle of measurement and communication. It is your ambassador for your roughest skills. It handles all the speaking and writing in language, graphics, and numbers. For hours, it is you, and you cannot have a discussion or a conversation along the way. You just provide the world with the final material. With this in mind, you can understand how critical the right arrangement and composition of the report are. This conclusion provides a chapter summary, followed by the recommended timeline for laboratory reports, inclusion of figures and tables, and novel approved data or references.
