Step 2: Article Analysis:

· Identify a “story” from the article. If the article is lengthy, you may opt to present only a portion of the paper.

· You will need to look at each portion of the paper and analyze it based on the guidelines below. The idea is not just to answer the following questions, but to think about what those answers actually mean. For example, if a study involved cell culture experiments, but they draw conclusions on human applications, is this flawed? Analysis does not mean “find all of the problems”. You will also need to think about what is done well as well as where it could be improved.

Article Analysis: What to consider for each section

Introduction/Objectives: Did the authors give a succinct statement of the problem, explaining why the research was conducted? What prompted them to do it? Briefly describe the “problem” and/or rationale for the study. What were the objectives? Did they have a hypothesis or overall re- search question? Were they clearly stated?

Methods: Describe the type of research design (this does not mean just repeat their methods) used for the study. Was it observational or experimental? What was the overall approach? (for example, did they first test in cells and then apply this to whole animals) Were criteria for well-controlled research utilized? If it was an experimental design, was the scientific method utilized? Were the research methods and/or study design care- fully described? (Did the authors provide enough information for you to replicate the study?) Were the methods and study design appropriate for meeting the objectives of the study? Were there any methodological flaws? Would there be confounding variables to consider? If so, what were they? Did they acknowledge these?

Results: What were the results of the study? Did they follow with the stated goals of the study? Were the findings reported without bias? Explain why or why not. How were the results reported? Could the tables/graphs, if used, “stand alone” without the written text? Can the study’s results be generalized to other populations? Why or why not? How does this work fit within the other research that has been conducted on this topic?

Discussion/Conclusion: Was the discussion pertinent to the objectives of the study? Did they overstate their conclusions? Have they considered alternative explanations? Was a critical evaluation made of the study, including methods and interpretation of data? Do they excessively speculate without data to back it up? Do they discuss working models and further studies? Were strengths and limitations noted? If so, what were some of the strengths and limitations? If not, what strengths and limitations would you note? Was the significance of the study discussed and what, if any, significance does it have? What applications do the findings have to the “real world”? What might the focus of future research in this area be? If you were conducting the study, what, if anything, would you do differently?

Overall Impressions: Is the writing clear? Did you feel like you understood what the basic goals and conclusions were? Did you have to read it over and over? Was the paper well organized or did you search for information? Was it interesting? Can you come up with questions based on the study? Do you think it was an important study?

Step 3: Article Analysis Write-Up

· Before the class period of your presentation, you will also submit a write-up of your analysis through Moodle. I am much more concerned with the quality of your analysis than the length of the paper, but if you have less than a single-spaced page, that is an indication that you are lacking detail. However, please do not exceed two single spaced pages (not including figures/data).

· Your write-up will likely not address every single question posed in the guidelines above as some will be more relevant to your chosen article than others. However, it should mostly cover the questions/issues addressed in each section of the analysis guidelines.

· You should have at least one paragraph for each section of the analysis (Intro/Methods/Results/Discussion/Overall Impressions).

· You may want to include figures/data in an appendix at the end if it is useful for following the points made in your analysis.

Step 4: Article Presentation

· Each student will present a summary of their analysis on their assigned day for approximately 10-15 minutes with an additional 5 or so minutes for questions. Most days will include presentations from more than one student. It is easy for presentations to go beyond the 15 minute limit, but professional presentations adhere to time limits! You will likely have more than 15 minutes’ worth of “share-worthy” information, so you will need to make sure that you have distilled your article down to what is really important. (The write-up will provide you with an opportunity to include more detail.)

· You are welcome to be creative and spark interest in class by sharing outside resources like visuals, handouts, etc. However, keep in mind that you will need to use the time wisely – don’t spend 8 minutes showing a video clip and two minutes rushing through your article information!

· The week before your presentation, provide the title of your paper and a copy of the abstract. This way, the rest of the class can quickly review it ahead of time to have an idea of what to expect from the presentation.

What to include in your presentation:

· Summary/Overview – what are you presenting? Why did you choose this article?

· Introduction/Background

· What is the big picture? Give enough background so that your audience understands why this study is relevant and why this field of research is important. You will want to define any important key terms that are needed to understand the paper. Make sure to include the goal/hypothesis of the study!

· Introductions usually begin broadly (the general field of research) and become more specific (ending with the particular research question addressed in the study)

· How does this study fit in to the larger body of research on this topic?

· Methods

· Briefly describe the overview of the study and methods (if applicable – sometimes it’s clearer if more detailed methods are included with the data instead)

· Diagrams and pictures are often very helpful here for clarity. For example, if your article is about a particular signal transduction pathway, a diagram of this pathway is crucial for understanding.

· Data

· Highlight a few key figures from the paper that really exemplify the main findings of the study; you likely won’t have time to cover them all.

· Walk the audience through the findings, using the figures. Don’t put anything on the slide that you aren’t prepared to discuss!

· Break down the major findings by answering: What? Why? How? What happened? Why do we care?

· Conclusions/Further Studies

· Present your impression of the article in support or contrast to the authors’ conclusions.

· You can also discuss the overall limitations or issues with the research design or conclusions.

· Describe the “real world” applications (social implications) of the study

· Make sure to end with a strong “take-home” message for the audience

· You should also include a references slide for any materials used in the background information or any images/outside resources incorporated into the presentation
