Specifically related to science instruction, research by Joyce Van Tassel-Baska suggests:
"Moreover, opportunities for earlier access to advanced content need to be available to gifted students in science. Cross and Coleman (1992) conducted a survey of gifted high school students, finding that their major complaint about science instruction was the frustration of being held back by the pace and content of courses. In a 6-year study of middle school age gifted learners taking biology, chemistry, or physics in a 3-week summer program, these younger learners outperformed high school students taking these courses for a full academic year (Lynch, 1992).
Follow-up studies documented continued success in science for these students, suggesting a need for academically advanced students to start high school science level courses earlier and be able to master them in less time. Evidence also suggests that advanced study in instructionally grouped settings based on science aptitudes promotes more learning for all students (Hacker & Rowe, 1993). Source:
