Journal Review Assignment (10% of your final grade)
The ability to read and distill papers in the primary scientific literature into short scientific reviews in your
own words is a critical skill and common practice in both academia and industry. For this assignment,
please pick from one of the 30 journal articles from the recent scientific literature listed below (all in the
broad area of tissue engineering, but broken down into more specific categories to help you guide your
selection). Once you select your paper, find it online (via PubMed or Google Scholar), download it, read it,
and then critically evaluate it. Your assignment is to then write a concise review/critique of the paper
summarizing the key findings.
(Note: If you REALLY want to read and review another paper of your choosing, you are welcome to do so.
However, you MUST get it approved by me in advance.)
Here are some guidelines.
• Your review should be concise! Please, no longer than 4 typed pages (single-sided, single-spaced,
Arial 11 pt. font with 1-inch margins).
• Your review should summarize the key methods utilized by the authors that led to their findings and
conclusions. However, you DO NOT need to summarize EVERY SINGLE EXPERIMENT or figure in
the paper.
• Your review should include your interpretation of the significance of the findings, and place the paper’s
results in a larger context. In other words, your review should assess how the results from the paper
impact a particular field or fields. This may require you to read (or at least be familiar with) other papers
in the field (for example, some of those we discussed in class or you read for the class).
Format: 4 pages maximum, single spaced, single sided, Arial 11-pt font, 1-inch margins
Executive Summary, describing the paper in your own words (0.5 page)
Summarize the key materials and methods (~0.5-1 page)
Summarize the data/results presented in the figures (~1 page)
Discussion (~1-1.5 page):
• The significance of the findings in your own words, putting this work into larger context
• Any weaknesses or concerns you have about the paper, how you might improve the paper, or the next
steps you would take in a subsequent study.
References (not required, but please cite any other references if you used any)
Grading Rubric
The assignment will be graded on a 100-pt scale according to the following breakdown:
• Executive summary (10 points)
• Accurate assessment of the key methods (20 points)
• Accurate assessment of the key results (20 points)
• Discussion of the significance of the paper in your own words (20 points)
• Discussion of any weaknesses or concerns you have about the paper, how you might improve the
paper, or the next steps you would take in a subsequent study (20 points)
• Conciseness and adherence to format (10 points)
