Question

There is an experiment. Amy wants to find out if reading a book that outlines teaching strategies helps one teach better. She will have all of the subjects read a book and then give a lecture to a class. The independent variable is the type of book read. The book is either a teaching guide or a visitor’s guide to Scotland. The dependent variable is how well the class does on a test given right after the lecture. It is a related samples design. Group A will read the teaching guide first, give a lecture, read the travel guide second, and give another lecture. Group B will read the travel guide first, give a lecture, read the teaching guide second, and give another lecture. Describe what the most likely carry-over effect would be for this experiment. Be precise in describing it and explaining what it would do (its ramifications).

Answer 1

>> A carryover effect is due to the treatment of same subjects which results in some experience of the subjects

>> For example in this research the carry-over effect is due to teaching. once the subject teaches it might make a subject better at giving lectures rather than reading a teaching guide.

>> So the sole purpose of this research design which was to measure the effect of reading teacher guide book to improve student test score is hampered

>> As the same person is now experience after giving the first lecture so he/she might get experience in teaching and become better. so the purpose of the research is disturbed. Therefore this the carryover effect here.
