The investigator completed a content analysis of the astronomy portion of science texts at three grade levels (4th, 5th, and 6th) that were produced by five different publishers. The analysis used an operant paradigm and compared the responses expected of students who used one science text to those expected of students using other science texts. The response comparisons were made both within and across grade levels. Using similarity of the responses expected of students as a basis of comparison, elementary school science texts produced by different publishers had more in common across grade levels than within grade levels. Less than 50% of the responses expected of students at one grade level were common to other science texts at the same or different grade levels.
