The text states that the scientists involved in this research found that the number of young children who were able to learn the concepts of the study in a normal classroom setting was much lower than the number of students who were able to learn the concepts in a setting where they were provided with one-on-one assistance. This finding suggests that there is a benefit to providing one-on-one assistance to children, but it does not necessarily mean that all children would benefit from such assistance, nor does it mean that one-on-one assistance would be the most effective approach for all children. What does the text suggest is the most likely reason for the results of the study?
