Critically reviewing a research article is not just about summarising the article, but evaluating the strengths and weaknesses of the article. It also looks at the value of the research conducted in context of similar research.
The following guides show to structure and write a critical review:

The Sage Research Methods Online database (SRMO) is a good source of full text electronic Books, chapters, and articles on a range of research methodologies. It includes a wide range of items in relation to literature review processes, and importantly how to read critically.

While most databases offer a peer review limiter, Ulrichsweb is the best place to confirm the peer review status of a journal. This is because Ulrichsweb isn't like most databases - instead of collecting articles, Ulrichsweb is a specialised database that collects information about journals.
Ulrichsweb can be found by clicking on the database listings under the letter U on the Library's Journal Databases page.
Articles published in peer-reviewed or refereed journals have been through a formal approval process. An editor and one or more subject specialists review the article before it is accepted for publication. This process is intended to ensure that the article is accurate, well-researched, and contributes to the body of knowledge in the field.
The subject area of a journal is important because it will impact the way someone writes about an issue.
To check if an article comes from a peer reviewed journal:
If you searched by journal title, you may get more than one result for the same journal. This sometimes indicates that there is both a hard copy and an electronic copy of this journal.
If you are unsure, you can always go back to the article record from your original search and get the journal's ISSN number from there. The ISSN is a unique number that is delegated to each journal.
Journals can be compared to measure their level of influence within the research community. Note that this measure applies at journal level, and not at article level. A high ranked journal may indicate that a journal is well-regarded.
The SCImago Journal and Country Rank (SJR) database can be used to compare and rank journals. ;SCImago does not include every journal; SCImago contains only those journals indexed in the Scopus citation database.
SJR publishes a range of metrics including an h-index (the number of articles n, that have that number of citations, n), and a quartile chart for each category based on its SJR score. The quartile chart is represented in the following way green=top quartile, yellow=second quartile, orange=third quartile, red=last quartile.
