By mid-course, your Math Journal stops being only a diary and becomes something rarer: evidence. The person who wrote your week-one entries no longer quite exists — and because that person wrote honestly, you can prove it. Showing growth means putting your week-one self and your now-self side by side and letting the difference speak.
Growth is a claim plus evidence
“I got better at math” is a claim, worth what any claim is worth: nothing yet. Growth writing pairs every claim with evidence from your own record — and the strongest evidence is the gap between two entries:
In the first unit I wrote that transformations lost me the moment all four parameters changed at once, and that I graphed by plotting ten points and hoping. Last week in The Tide Problem I was the one saying “axis first, then amplitude, then period — leave the shift for last”, and I had the equation drafted before anyone reached for a table of values. The recipe stopped being a spell and became the actual tool.
The claim is the recipe became a tool. The evidence is two moments, months apart, both on the record — and nobody can argue with that, including the part of you that suspects you have not changed. It is the standard How Marks Work applies everywhere: what can you point to?
How to cite yourself
Treat your earlier entries the way an essay treats sources:
- Date it — “In my second-week entry…” — the distance matters.
- Quote a phrase, not a page. Your words from the time carry more truth than your summary of them now. “Obvious is apparently not a reason”, from Your First Entry, says more than “I used to skip justification.”
- Then show the now. A recent moment, just as specific, that the earlier self could not have managed — or would not have noticed.
Growth is not always getting more answers right
Some growth is speed traded for depth. Some is a new noticing: a graph whose period smells wrong on the sketch, a constant ratio in Visual Patterns that was invisible in the first week. New noticing is growth, and your early entries prove it was not always there.
