It depends on the type of text. If it's a conversational style text, it would certainly benefit a learner to read it aloud to practice pronunciation, natural intonation and so on. I can't see how it would harm a student's chances of passing reading tests to read aloud. It depends on the individual student's learning style. Some people are naturally more 'verbal', and reading aloud may help them understand the text. It's just rather time-consuming, and - in the case of more formal academic texts - it wouldn't be practising a worthwhile skill. Such texts aren't meant to be read aloud, so they would be better used to develop the student's 'eye to page' skills, skimming, scanning and so on.

Thank you, Neil. I appreciate your help. Can I replace "yourself" with themselves"?

Since you are asking about a "learner" (third person), the word "yourself" (second person) in the question is not appropriate. Here are some ways to finish the question: " ..... read aloud or to himself?" "... read aloud or to himself or herself?" Informal: "... to read aloud or to him or herself?" In the last variant, it is understood that the word "him" is also associated with the syllable "self" in the word "herself". That is, "him or herself" is an abbreviated, informal way of saying "himself or herself."
