i think there are many critique form. it depend on what type of research study!
It entails writing about the strength and weakness of an article. Remember not to concentrate on the weaknesses.
For writing critique if you want to secure maximum marks your focus should be on both strength and weakness of the study.start by study statement,objectives,operational definition,hypothesis,research methodology,data collection (results nd findings)data analysis,conclusions, implications......each step should be clearly written with strength and weakness ..hope it will be helpful for you to attain maximum marks .....
I've always found that writing a force field analysis gives me a good roadmap of important facts to research and write about.
Do the critique based on substantive & theoretical, ethical, methodological, Interpretative and presentational dimension of both strength and weakness of the research study. It should identify gaps within the study’s research process as well possibilities for future research
