Scholaric Blog

At the Midwest Parent Educators Conference, Scholaric was put to the test.  A new user signed up, set up a course and wanted help entering a complex repeating lesson.  It is a useful case study to explain what Scholaric can do, and how to go about analyzing.

The facts have been changed to protect the innocent...

"My Math program has 25 lessons, each of which are divided into 6 parts, a, through f..."

Okay, no problem Scholaric handles that.

"...but we do 2 parts per day..."

Sure, Scholaric does that too.

"...AND we are on lesson 7, and have already done parts a and b of it..."

That's a lot to consume, but we want to generate

Lesson 7 parts c-d
Lesson 7 parts e-f
Lesson 8 parts a-b
Lesson 8 parts c-d
Lesson 8 parts e-f
Lesson 9 parts a-b
Lesson 9 parts c-d
Lesson 9 parts e-f
...

and so on.  

Breaking this down, it first is a nested sequence, an outer numeric sequence {7-25} and an inner alphabetic sequence {a-f}:

Lesson {7-25} parts {a-f}

But that would be one part per day.  To do 2 parts per day, we need to use the group operator * (increment it two times per day):

Lesson {7-25} parts {a-f*2}
