Fresh frog spawn looks like a rather tight well defined lump. As the eggs develop they do go to look mushy, and very quickly. A frost will kill any exposed frog spawn, and that goes white and breaks down very quickly, under the water there will still be developing eggs which if left alone will hatch into tadpoles. The tadpoles will feed on the dead spawn, tadpoles are cannibals.
I'd be patient, it's not pretty I grant you, but leave it. It's nature behaving the way it should behave and nature can be ugly at times.
They wont take too long to hatch, just watch and get the kids too look at as well.
It's all a good natural history lesson for them.
Mollis has got it right with the oxygenating plants and marginals, and the debris/pond life.
Even in a neglected pond there will be resident wildlife.
