And since it is between two given points students can use the distance formula to find the length, so it does not have to be provided they would just need the given points and the ratio.

I don't think it is midpoint. My understanding is that we are looking for the two segments of the line that are in a specific ratio. If the total length is provided we can then locate the point that divides the line segment into the given ratio.

Has anybody started to write curriculum for the common core High School
courses?
Here is one standard for Geometry : G.GPE.6 Find the point on a
directed line segment between two given points that partitions the
segment in a given ratio.
Do you think this means find the midpoint? (that is what I found on one
website)
or they have to find a point between two given points such that the
ratio of the segments is 3:4 (for example) ? What do they expect the
students to do to find this out?
Anybody???
