At beginning levels, except for the basics (subject, verb, present tense, etc.), the technical terms aren't really important. Students need to see the pattern of a particular language point, and drill the pattern until it becomes somewhat automatic. At that level, long grammar explanations don't benefit the students. Practice (and more practice) gets them using the language correctly.
This applies to intermediate students, too. However, if you've been introducing basic terms, then this greatly aids comprehension of more difficult terms with intermediate and advanced students.
