Command terms are key terms that are used in exam questions to ask questions. The following link takes you to a PowerPoint that helps explain the meaning for each, within the old syllabus – last exam 2015. [Check out the very useful sortable syllabus below the embedded PowerPoint on the website.]
I have graded many exam papers that have left me pulling out my hair as I read students demonstrate an understanding of the content tested, BUT due to a lack of understanding of the command term, have answered a question that was never asked and not answered the question that was.
One that is commonly mis-understood is Analyse –
Break down in order to bring out the essential elements or structure. (New definition – first exam 2016)
Interpret data to reach conclusions. (old definition – last exam 2015)
Another is Compare-
Give an account of similarities and differences between two (or more) items, referring to both (all) of them throughout. (old definition – last exam 2015)
For this blog I am not going to post the new definition for fear of confusion.
Commonly asked exam questions that use COMPARE as a command term include
Compare mitosis and Meiosis
Compare spermatogenesis and oogenesis.
To that end, I have posted videos on each topic and a video that compares each. Also, check out this website that is dedicated to comparing (but does not have a page on gametogenesis)
Go check out many other videos from the Amoeba sisters on Genetics if you like these etc
Explore the differences and comment on the following:
- The number of cell divisions
- the organisation of homologous chromosomes
- the number of cells produced
- variety / identical
- How variety is achieved / not achieved
Make notes the processes they have in common
To explore the differences comment on the following:
- the stage of life at which the process initiates.
- the stage of the process at which meiosis I and II progresses.
- the number of mature gametes produced from a primary germ cell.
- the number and timing of gametes released.
- the length of time the process takes,
