IB Spanish B · Writing and grammar

“I understand everything.” So why is the grade a 5?

It is the most honest sentence in language learning, and the most misleading.

I hear it in almost every first lesson: “I understand everything, I just cannot write it.” Often that is true. Many students listen well, read well and speak with a good accent. And still the written work comes back with the same errors, term after term.

The recognition illusion

Understanding is recognition: you see “estuvo” and your brain says “yes, that looks right”. Writing is production: you have to build “estuvo” from nothing, choose the tense, the verb and the ending, and spell it. Series, apps and holiday conversations train the first skill beautifully. The exam, mostly, tests the second.

Where the points leak

  • Tense choice: “Me gustaba mucho la fiesta” when the party was a single event (“Me gustó”).
  • Ser and estar: “toda la atención está en ella” versus “es”, depending on what you mean.
  • Agreement: “me gustaron los tacos”, not “me gustó los tacos”.
  • Small words and spelling: “para la fiesta”, not “por la fiesta”; “posible”, not “possible”.

None of this is a comprehension problem. It is a production problem, and it only improves when the student produces and gets corrected.

The cover-and-write test

Choose a short paragraph the student has read and “understood”. Hide it. Ask them to rewrite it in their own words, by hand, in ten minutes. The distance between what they understood and what they wrote is the real gap, and it is the thing to train.

Fluency in the ear does not automatically become accuracy on the page. The bridge is small, frequent writing with fast feedback.

For the adult who pays for the lessons

An app streak or a confident “yes, I get it” is not evidence of exam readiness. Better evidence: ask to see a handwritten paragraph written without notes, and ask your child to explain, in Spanish, why one verb is in the past tense and not another. If they can do both, the plan is working. If not, the plan needs changing, and that is useful to know in October rather than in April.

What actually closes the gap

  1. Short pieces of writing, often, instead of one long essay each month.
  2. Every error sorted by type, so the pattern becomes visible.
  3. The same structures rewritten correctly until they come out automatically.

If you want the pattern found and fixed, book an assessment lesson below and we will see exactly where the points are leaking.
