to be accompanied by such things as rainbows and jumping frogs

This text is from Critical Thinking for Students: 3th edition (Roy van den Brink-Budgen) page 47:

For 20 years, children have been treated to all sorts of programmes on television which are supposed to help them become better at skills such as reading and maths. These programmes have presented the learning of skills such as counting and recognition of letters as nothing but fun, to be accompanied by such things as rainbows and jumping frogs. But no improvement in children's abilities in literacy and numeracy has been observed. These fun ways of teaching such skills obviously don't work.

I do not understand the meaning of the bold part. Please answer these two questions:

1. Is the bold section grammatically correct (in the context of the sentence)?
2. If the answer to #1 is "Yes", then what the author wants to convey?

1. Yes.
2. It's meant literally. The TV programmes typically include such fun things as rainbows and jumping frogs.
