How to turn Spanish grammar study into useful practice
You can understand a grammar explanation and still hesitate when you need the form in conversation. The explanation may be useful without being the whole of the practice you need.
Rather than choosing between rules and examples, connect them. Use a rule to understand a sentence, practise the choice and return to it when reading, listening or expressing something of your own.
Find out what is missing
For different mistakes you need different work. If you cannot explain the difference between fui and iba in a passage, you can learn it from a focused explanation. If you understand it but cannot recall the form fui, practise the form. If you can complete an exercise but hesitate in conversation, add practice using it in replies.
Do not infer a precise mental process from one error. Behind a wrong answer there can be misunderstanding, an unfamiliar word, a lapse in attention or difficulty producing a form under pressure.
Explanations can help learning
With explanations, people can learn to use grammar as well as describe it. In Spada and Tomita’s 2010 review of studies, explicit instruction in English grammatical features had benefits, including on measures of spontaneous use. That is evidence for giving an explanation a place alongside practice, and you can still choose the format that suits a particular difficulty.
Check a rule through several tasks. Recognise the pattern in a passage, complete a sentence with it, then write an example of your own.
Work through a small example
Suppose you confuse es aburrido and está aburrido. First check the meanings: with the former, people commonly describe someone or something as boring; with the latter, someone as bored.
Then compare situations. A film you have no interest in can be aburrido. A person waiting with nothing to do can be aburrido with estar. Produce complete sentences and check that they mean what you intended.
Later, notice the words in a text or recording. Try another sentence without consulting the first examples. That way you apply the explanation several times, and it is more than a rule you once read.
Use tables when they answer a question
In a conjugation table you find forms and compare patterns. You can see in it that hablo and hablamos share a verb while differing in person and number.
If you can recite a row but cannot find the form you need, practise forms in a different order and in meaningful sentences. You can retain the table as a reference. There is no need to treat it as either the entire method or a forbidden tool.
Ask for focused feedback
When a correction is unclear, ask what changed: the grammar, the intended meaning or the style. A natural alternative is not always evidence that the original was ungrammatical.
Keep a small number of recurring difficulties to work on. Check a reliable explanation, compare examples and practise the choice in another context. You can do that work with Vozelu’s grammar material and exercises; how the parts fit together is on the method page.
After a useful grammar session you can understand or say something more clearly. That is a better test of the session than whether there was a rule list, a table or an exercise with a blank in it.
